Hello again, fans of science,

GOOD NEWS

For the first time in 75 years, the population of the flightless New Zealand Kakapo (Maori: parrot of the night) is up to 325 birds thanks to huge conservation efforts and fruiting rimu trees. These 4 kg birds only mate during years when rimu berries are abundant.

The U.S. is currently experiencing “Very Low” incidences of acute respiratory illnesses.

21 minute video of Good News: Africa electrification, Amazon rain forest preservation, Earth’s fungal network, the Green Economy, Przewalski Horse rewilding, rebuilding Australian habitats, Central Arctic Ocean Fisheries Agreement, UNESCO Sites, HPV vaccination success, DNA wildlife survey, wildlife over- & under-pass construction, invasive rat removal, satellite detection of wildfires, & more. 

A ‘dark matter’ particle may have been detected. There is far more dark matter in the Universe than ‘regular’ matter, but attempts to detect dark matter have been fruitless – until now. The potential detection was found after reëxamining data from over 200 days of observations carried out with the LUX-ZEPLIN experiment 1.5 km underground in South Dakota. The event had been overlooked previously since the team was looking for a less energetic event. They are now reëxamining another 400+ days of data looking for a similarly energetic interaction.  Video – 13 mins

The BepiColombo probes are now approaching Mercury at the planned velocity and have jettisoned their ion thruster module. The BepiColumbo mission consists of two conjoined space probes:  the European Space Agency (ESA) Mercury Planetary Orbiter (MPO) and the Japan Aerospace Exploration Agency (JAXA) Mercury Magnetospheric Orbiter (Mio). The mission launched eight years ago from French Guiana. It would have whizzed past Mercury at 37 km/sec had it not used gravity assists to slow down.  It used the Earth once, Venus twice, and Mercury six times to scrub off speed. In December, Mio will detach from MPO and they will each go their own ways collecting data.

Vaccination rates in California exceed the National average across the board.

A “Correct the Map” resolution was introduced in the United Nations on Friday by Togo on behalf of the 54-nation African Group and subsequently passed. [The only “No” vote came from U.S. Representative Yaryna Ferencevych who stated that the resolution promoted an “ideological agenda.”] The resolution encourages the use of Equal Earth Projection maps. The Mercator Projection (by Gerardus Mercator in 1569) was a boon for early ocean navigation since a straight line between any two locations gave the compass heading needed to get there [after correcting for magnetic declinations]. As a ‘geographical map’, however, the Mercator Projection exaggerates areas closer to the poles (as shown by the animation above). Also, great circle routes are shorter than Mercator’s constant heading routes. Computers and GPS now make the Mercator Projection pointless. The Equal Earth Projection above indeed shows correct proportions of lands and seas, and it can be created to center on any line of longitude. 

Best of course is a world globe, unless you need it on page 42 of your report.

SPACE

A hand-me-down went to space Sunday morning.  The Nancy Grace Roman Telescope with a decades-old mirror donated by The National Reconnaissance Office (NRO) is on its way to Sun-Earth Lagrange Point 2.  The mirror is basically the same as the one in the Hubble Space Telescope, which also came from the NRO.  Those two mirrors were intended to be used in spy satellites developed by Boeing (with insane cost overruns, of course). Fittingly, Ms. Roman initiated the program to create the Large Space Telescope (later named the Hubble Space Telescope) and led the design of its mission and instruments.

¿What will the Roman Space Telescope be doing?  It has a large field of view which lends it to find thousands of exoplanets, study the nature (or infer the non-existence) of Dark Energy, and survey billions of galaxies for interesting stuff that JWST and Hubble could then study in greater detail.

Deadly floods have been a common feature throughout the history of life on Earth. However, avalanches and floods from melting glaciers are increasing in frequency – as expected due to global warming. Hopefully none will be as deadly as we witnessed this last week. [Last year i wrote about the destruction of the Swiss village of Blatten by a rock-ice avalanche.]

• NOAA (National Oceanic & Atmospheric Administration) pulled its support of the annual Arctic Report Card;
• The National Academies, the nation’s top scientific body, removed the chapter on climate science from its reference manual for judges;
• Although other factors are involved, political party affiliation continues as the strongest predictor of attitudes toward climate change.

Hello again Science fans!

August has been a month full of astronomical events, what with the total eclipse of the sun over much of Europe coinciding with the Persied meteor shower earlier this month. The fun continues with an almost total eclipse of the moon (96%) on Thursday evening, August 27 that will be visible here.

Eclipses occur when one astronomical body crosses in front of the sun with an alignment that blocks light to another body. For a solar eclipse, the Moon passes between us and the Sun at just the right distance to totally block sunlight from view, if you happen to be in the path of totality anyway.

For a lunar eclipse, Earth gets between the sun and moon such that the shadow cast by Earth blocks sunlight from reaching the moon. A lunar eclipse will always occur either before or after a solar one, but the opposite isn’t true, all due to orbital mechanics.

Astronomer Andrew Fraknoi has prepared an information sheet for the lunar eclipse that you can download here with times, diagrams, and viewing suggestions. Thanks to Andrew for providing this information!

We all live on Earth, a rocky planet with a rocky moon, orbiting a rather ordinary star, along with 7 other planets and assorted comets and asteroids. Our star exists near the end of one of the spiral arms of a galaxy we call the Milky Way, which contains billions more stars and planets.

Neither our Sun, nor the Milky Way itself look now like they did millions of years ago. The Milky Way has grown over time, forming new stars, as well as collecting stars, gas, and dark matter from other, smaller galaxies through mergers. We are still merging with the Sagittarius dwarf galaxy, and have been doing so for over 6 billion years. About 10 billion years ago, we merged with Gaia-Sausage-Enceladus, which significantly changed the structure of the Milky Way.

Using observations from the Hubble Space Telescope and the Gaia spacecraft, scientists now have determined we merged with a galaxy called LKH around 11.8 billions years ago, just 2 billion years after the Big Bang. How they discovered this is a tale!

Closer to home, the makeup of a rare meteorite provides history of an ancient planet that was once in our Solar system. It may have been as large as Mars. Again, the story of how astronomers determined this is fascinating.

A limited number of telescopes exist for astronomers to use to collect data. The existing telescopes look at different wavelengths of light, exist on different parts of the planet or in space, and have different resolutions. Up until now, astronomers have used a manual method to schedule who gets time on a particular scope, and how that time is used.

A couple of astronomers trained AI on the decisions astronomers made in determining where to point the telescope at any particular time. After many learning iterations, they now have an AI-driven model that can predict the best use of the telescope, and automatically aim it to the right spot in the sky.

Friday’s New York Times Science newsletter contained a picture of a poster hanging at the Jet Propulsion Laboratory near Pasadena which I’ve included above. It shows the distances various rovers have gone on both the Moon and Mars. Two are still active, Curiosity and Perseverance, both on Mars. While the poster itself dates to 2024, the numbers for these two rovers continue to be updated manually. Perseverance is expected to pass the distance record set by Opportunity, which ceased operation in 2018, within the next two weeks. It has about 590 feet to go to break the record.

A few months ago, we wrote about the Swift space telescope, which is in danger of reentering the atmosphere. NASA launched a crash program to develop a spacecraft to dock with Swift and push it into a higher orbit. Unfortunately, that mission failed and the rescue craft is spinning out of control. As a result, Swift will disintegrate during re-entry later this year.

Turning to AI, scientists trained a model on libraries of DNA and asked the model to create new, viral genomes. Of the hundreds or recipes created, 16 of them were viable. What could possibly go wrong?

Meanwhile, the FDA has approved Moderna’s new mRNA flu shot for adults 50 and over. It performs better than the existing standard-dose vaccine. Using mRNA technology should allow the flu vaccine to be adjusted to match dominant strains of the flu much faster.

What is the hardest substance in the human body? Tooth enamel. Its weakness is that it can’t regrow, unlike bones. Scientists have found a way to regrow enamel, and it could be available commercially next year! This could revolutionize dentistry.

Science communication is a topic we write about frequently here. UC Santa Cruz is offering two new introductory courses, both aimed at STEM professionals who want to learn about, or improve communications skills. The first course begins September 29. The second is planned for January, 2027. Both are online. Here’s more information on the courses, if you’re interested.

Have a great week in science!

A love letter to the wildest place in the Bay Area, written from inside a fog bank.

Greetings, science fans!

It is Fogust in San Francisco, and I have not seen the sun in what feels like several geological epochs. Karl has taken up permanent residence. Gray has been replaced by different shades of gray.

This weekend, I took a walk out by Ocean Beach, squinting through the mist, knowing that somewhere out there, the Farallon Islands are doing extraordinary things without me.

I have never been. Most people haven’t. The islands are closed to the public and accessible only to the small crew of researchers from Point Blue Conservation Science who have maintained a continuous presence on Southeast Farallon Island since 1968.

But I have spent an unreasonable amount of time reading and watching accounts from the lucky few who have made the boat trip out. Their stories tend to include the same things: the 2.5-hour crossing through notoriously rough seas, the moment the islands suddenly appear out of the fog, and, before anything else, the smell.

Elephant seals. Hundreds of thousands of seabirds. Decades of accumulated biological activity on a small rocky island with nowhere for any of it to go. People describe the smell with a kind of reverent horror. One journalist wrote that she smelled the seals before she saw them.

Then there are the sounds.

Western gulls shrieking from their nests. Hundreds of thousands of common murres making a strange, kazoo-like call that carries across the water. Sea lions grunting from the rocks in such numbers that the sound reverberates off the surrounding islands.

And then there is the sheer scale of the place. The Farallones are home to the largest seabird nesting colony in the contiguous United States, with roughly half a million birds representing 13 species. At the peak of spring breeding season, more than 300,000 common murres nest there alone.

The science coming out of this improbable place is pretty extraordinary, too. Because Point Blue has had researchers there continuously since 1968, the Farallones have produced one of the longest-running wildlife datasets in the American West, tracking population numbers, diet, and reproductive success across seabirds, seals, sea lions, and white sharks.

Each fall, somewhere between 15 and 50 great white sharks arrive after their annual migration across the Pacific. And they are there for a very specific reason: young northern elephant seals, arriving at the islands for the first time after their first summer at sea, fattened up and blissfully unaware of what is waiting below. Point Blue researchers typically see the first predation event in late August, with numbers increasing through September and peaking in October.

In 2023, global sea surface temperatures reached record highs, while a prolonged El Niño pushed temperatures around the Farallones a couple of degrees above the long-term average. Some seabirds responded by delaying breeding, laying fewer eggs, or abandoning nests altogether, essentially deciding to keep the resources for themselves rather than spend them raising chicks. As we brace for one of the strongest El Niño events ever seen, I wonder what that means for the future of the tiny islands.

On Wednesday evening at the San Mateo Public Library, Gerry McChesney, Refuge Manager with the U.S. Fish and Wildlife Service, will talk about the islands’ history, wildlife, and management. For most of us, it is about as close as we’re going to get to one of the most extraordinary wild places on Earth, sitting just over the horizon from our own backyard.

If you want to get a little closer, the Oceanic Society has been running full-day whale-watching trips to the Farallon Islands since 1972. They leave from San Francisco on weekends from April through December aboard their 60-foot vessel, the Salty Lady. Shark Stewards and Marin Audubon also run trips in the fall, timed to the return of the great whites.

You can’t set foot on the islands, but you can get close enough to see the murres, elephant seals, and, if you’re lucky, the sharks. And yes, you can smell it.

We generally don’t send out more than one newsletter a week, but occasionally omit something important and timely. So here’s a quick SciSchmooze extra to cover two astronomical happenings this week.

This Wednesday evening and Thursday morning one of the better meteor showers of the year, the Perseids, will be visible. The shower is caused by Earth’s passage through the debris trail of comet 109P/Swift-Tuttle each August. This year, the shower will occur at the same time as a new moon, so the night sky will be darker than usual, meaning more meteors should be visible.

Andrew Fraknoi has provided details and viewing instructions for the Perseids here.

Also, on August 12 a total solar eclipse will be visible over much of Europe. We won’t see anything here in the US, but NASA is providing online coverage from the path of totality, as well as from a plane chasing the shadow. You can watch the coverage here.

“The human foot is a masterpiece of engineering and a work of art.”
— Leonardo da Vinci

With another San Francisco Marathon officially in the books, thousands of runners are currently nursing sore calves, proudly displaying their finisher medals, and slowly regaining normal metabolic baseline. Winding through 26.2 miles of foggy coastlines, steep city gradients, and an iconic sunrise crossing over the Golden Gate Bridge, the SF Marathon is widely considered one of the most scenic—and biomechanically demanding—urban races in North America.

First run in 1977 with a humble field of fewer than 1,000 entrants, the event has expanded into a global spectacle drawing over 30,000 runners. And as we look ahead to next year’s historic 50th anniversary in 2027, it’s worth stepping back to examine the sheer physical reality of what happens when human physiology collides with classical mechanics on the streets of San Francisco.

Grab a high-electrolyte drink—it’s time to break down the science of the stride.

1. Bioenergetics & Thermodynamics: The Human Radiator

Every marathoner fears “The Wall” at Mile 20—a psychological and physical abyss where the legs feel filled with wet cement. But “The Wall” isn’t a mysterious mental barrier; it is a hard bioenergetic boundary.

Your body stores approximately 2,000 kcal of easily accessible glycogen in the liver and skeletal muscles. At a typical marathon pace, you burn roughly 100 kcal per mile. By Mile 20, your primary carbohydrate fuel tank is bone dry, forcing your metabolism to switch to fat oxidation. Because fat requires significantly more oxygen to break down, your energy output drops off a cliff.

However, fueling is only half the thermodynamic equation. The real boss fight of marathon running is heat dissipation.

Biophysically speaking, humans are magnificent radiators but terrible engines. Human skeletal muscle operates at only 20% to 25% mechanical efficiency when converting chemical energy into forward motion (Gaesser & Brooks, Journal of Applied Physiology). The remaining 75% to 80% is converted directly into pure waste heat. If your body’s physics can’t shed that thermal burden fast enough, your central nervous system triggers protective fatigue to prevent hyperthermia, forcing you to slow down or stop regardless of how much fuel remains in your tank (Nielsen et al., Pflügers Archi).

This physical reality aligns directly with evolutionary biomechanics (Bramble & Lieberman, Nature). As Harvard human evolutionary biologist Dr. Daniel Lieberman puts it:

“We are terrible sprinters compared to other mammals, but we are magnificent long-distance runners… Humans can dump heat faster than almost any other animal because of our hairless skin and millions of sweat glands. A human running in the heat is basically a specialized cooling tower on legs.”

This is where San Francisco’s famous microclimate gives runners a distinct physical advantage. The cold marine layer rolling in off the Pacific Ocean provides an optimal external heat sink. Through convective and evaporative cooling, the low ambient temperature allows the body to reject waste heat far more effectively than in warm-weather marathons, keeping the central nervous system from pulling the emergency thermal brake on performance.

2. The Physics of Motion: Vectors, Overstriding, and Super-Shoes

If thermodynamics governs your internal engine, classical mechanics dictates how efficiently that engine moves across space.

The Vector Penalty of Overstriding

When fatigue sets in around Golden Gate Park, many runners naturally lengthen their stride in an attempt to maintain speed. From a physics perspective, this is a major tactical error.

Every footstrike generates a Ground Reaction Force (GRF) vector. If your foot lands directly beneath your hips (your center of mass), that force vector is almost purely vertical, supporting your body weight against gravity. But when you overstride—landing with your heel far in front of your body—you create a horizontal braking force vector (F_x) pointing backward.

In essence, overstriding means tapping your biological brakes with every single step, expending precious metabolic energy just to re-accelerate your mass back up to speed (Heiderscheit et al., Medicine & Science in Sports & Exercise).

Materials Science in the Midsole

To combat impact stress and mechanical energy loss, modern runners have turned to high-performance polymer engineering: the “super shoe.”

Traditional running shoes used standard Ethylene-Vinyl Acetate (EVA) foam, which absorbs impact but only returns about 60% of stored mechanical energy. Today’s elite marathon shoes utilize Polyether Block Amide (PEBA) foam—a lightweight, highly resilient thermoplastic elastomer that yields an extraordinary energy return of 85% to 87% (Hoogkamer et al., Sports Medicine).

When paired with a curved, rigid carbon-fiber plate, these shoes don’t act like springboards pushing you forward. Instead, the rigid plate acts as a mechanical lever at the ball of the foot (the metatarsophalangeal joint), preventing excessive toe bending and allowing the calf-Achilles complex to work at a far more biomechanically efficient angle.

3. Data-Augmented Running & California’s Endurance Heritage

We are living in the era of the quantified runner. Beyond simple GPS watches tracking split times and elevation profiles, today’s athletes rely on real-time physiological telemetry:

• Continuous Glucose Monitors (CGMs): Providing live estimates of blood glucose trends to optimize carbohydrate gel timing before hitting the bioenergetic wall.
• Microfluidic Sweat Patches: Analyzing electrolyte concentrations (specifically sodium and potassium loss) to prevent cramping and hyponatremia.
• Integrated Accelerometers: Measuring ground contact time, vertical oscillation, and stride symmetry to alert runners when their form begins to degrade into braking vectors.

Yet, long before wearable sensors and PEBA foam existed, California was the birthplace of raw ultra-endurance running.

Consider Ann Trason, a legendary Bay Area local, former science instructor, and widely regarded as one of the greatest trail runners in human history. Trason famously won the grueling Western States 100-Mile Endurance Run an astounding 14 times. Long before algorithms optimized race execution, Trason applied a rigorous, almost scientific mind to ultra-endurance—treating pacing, metabolic intake, and terrain strategy like a precise laboratory experiment while outrunning both women and men across the Sierra Nevada mountains.

“Running an ultra is really just a 100-mile science project. You are the test subject, and your job is to constantly solve the physiological puzzle as the variables change around you.”
— Ann Trason, 14-Time Western States 100 Champion

The SciSchmooze Skeptical Twist

As microfluidic sweat patches and real-time CGMs turn runners into walking telemetry stations, we have to ask a foundational question: is data-augmented running sharpening our physical insight, or blunting it?Evolution spent millions of years fine-tuning human interoception—the complex network of neurochemical feedback loops that tell us when our core temperature is spiking or our glycogen is depleted. When we outsource that self-awareness to an algorithm on a wrist display, do we risk losing touch with the raw biological signals that athletes like Ann Trason used to conquer 100-mile wildernesses? Real-time data can inform the strategy, but it can never replace the art of listening to the machine from the inside.

May your friction coefficients remain high, your ground reaction forces stay vertical, and your thermodynamic systems find steady-state equilibrium.

Structurally yours,
Lili

Hello again appreciator of science,
Ahoj znova, milovník vedy,
[Over 300 million people speak a slavic language]

BIOLOGY / ETHOLOGY

Let me share what i recently learned about some extremes of human perception. One to two percent of people are ‘super-recognizers’. They easily recognize people years after a brief encounter. [Definitely NOT me.] People with prosopagnosia have difficulty recognizing anyone; even their spouse or their own reflection in a mirror.  Also there are people with aphantasia – they cannot bring to mind the appearance of anything. They simply cannot create a ‘mental picture’ of a person, a top hat, a fire extinguisher, a camel, anything.

Imagine what life for these two extremes of people might be. Some – if not most – birds are super-recognizers. Penguins distinguish which of hundreds of chicks is their own. The International Bird Rescue Center  was rehabilitating an injured Brown Pelican who aggressively threatened the executive Director regardless of what she wore, but regarded everyone else with calmness.

What most of us do countless times a day we simply take for granted, but we are constantly relying on a brain that has been honed by evolution for nearly a billion years. Brains are incredibly complex – likely the most complex organ in this sector of our Galaxy. Use it joyfully and use it wisely.

The moon will get smacked by a 14 meter-long section of a SpaceX rocket Tuesday night at 23:35 [11:35pm] Pacific Time moving 8,800 km/hr [5,500 mph]. It is the second stage of a rocket that propelled two lunar landers in January 2025. It won’t be visible, however, except with a strong telescope.

RAFFLE

This cap is one of dozens of  science-themed caps that the winner will choose from for this SciSchmooze Raffle prize.  Just send an email before noon Friday to david<dot>almandsmith@gmail<dot>com with your guess of an integer from 1 to 1,000. In our previous Raffle, the eOracle offered up 199.  Of the 19 entrants, Taylor was closest with her guess of 222, winning a 450ml borosilicate coffee beaker/mug. 

A “Thank You” goes out to our many readers who submitted comments on the OMB’s proposed rule that would give political appointees total discretion over federal funding of scientific research.  Nationally, over 300,000 comments were submitted.

CLIMATE

¿Gradually evacuate New Orleans?  That is the recommendation of a scientific paper published in Nature.  This idea was widely circulated after Hurricane Katrina 21 years ago that resulted in over 1,300 drownings and $200 billion in damages. Most of New Orleans is already below sea level, it continues to sink, and our oceans continue to rise. 

¿Is the world threatened by a ‘suicidal’ model of capitalism?  “Yes,” says Colombia’s president Gustavo Petro.  At April’s Climate Summit in Colombia – the world’s first international conference on transitioning away from fossil fuels – he identified the fossil fuel industry as a cause of global problems.

Our federal government is required to issue a “National Climate Assessment” every 4 years. The Internet portal to all five previous assessments has been shut down.  A climate science denier, Matthew Wielicki, has been selected to oversee production of the sixth National Climate Assessment.

ENVIRONMENT

Most of the heat gained by our Earth since the Industrial Revolution resides not in the atmosphere, but in the oceans. The oceans have many circulatory systems going in many directions with considerable differences in temperature and depth. Those systems intimately affect the weather. ¿How best do we study ocean circulations and their temperatures? Answer: with expensive expeditions using ships and undersea scientific submersibles – or with sharks. Researchers capture sharks that naturally move between the surface and the depths, attach electronic modules to their fins, and let them free.  When a shark breaks the surface, the module transmits recorded information on depth, temperature, and location to satellites. Cool!

While at the National Center for Science Education, i worked alongside Peter Hess. Since then, one of his sons [with others] developed a smartphone app that tracks fires and floods called “Watch Duty”.  Their app just got coverage in the New York Times. Kudos!

Bad Idea of the Week Department:  Hey, wouldn’t it be great to have giant mirrors orbiting Earth to reflect sunlight to construction sites at night – or power solar farms at night – or light up agricultural harvesting in the cool of the night?  On the negative side: interfering with astronomy (including burning the eyes of astronomers), affecting diurnal rhythms of plants and animals (& humans?), raising the probability of the Kessler Syndrome, diminishing the beauty of the night sky, and likely more ill sequelae. The federal administration has given the go-ahead to test this idea.

Empathy requires highly sophisticated brain functions in multiple regions. [Anterior Insula, Anterior Cingulate Cortex, Amygdala, and the Mirror Neuron System] Not everyone is capable of feeling empathy toward others, but most humans and many other mammals are indeed capable. Humans, however, also have the ability to limit empathy towards other people on the basis of religion, political attitudes, nationality, sexuality, etc.

Hello again fans of Science!

I’ve just returned from a long road trip. Maybe I’m outside the norm about this, but I enjoy long drives. I always have. I rarely listen to music, or audio books. I enjoy the quiet reflection such time can give.

The scenery doesn’t change much from year to year, but it does change over the course of hundreds miles…from lush, green forests to farmland, then grasslands, then dry desert, from flat lowlands to mountains and everything in between.

One other thing that can change is roadside hotels, both existing ones being remodeled and new ones being added. Both bring the science of design to bear on what should be fairly straightforward…a quiet, comfortable place to rest overnight. Little details can make a big difference, and some things I saw this year make me wonder if the designers (or the people that approved the designs) ever spent a night in a hotel! As perhaps you can tell, I had a lot of time to reflect on this during the trip.

I stayed in a Hampton Inn (a Hilton chain) that was undergoing a refresh in the rooms and common areas. I can’t say I liked the new room design, but it wasn’t awful either. There seemed to be less in this new design than in previous iterations…less storage, less convenience. For example, no towels reachable from the shower, and no place to hang one nearby if you noticed that before you got wet.

Then there was the Tru by Hilton I stayed in. This was my first Tru stay, and I really have to wonder what they were thinking. There were no lights on the night tables, which weren’t really tables in the true sense, but shelves by the bedside. There were two LED can lights in the ceiling over the head of the bed, and one standing lamp in the corner. I was traveling alone, but imagine if you were with someone else and had to get up in the middle of the night. You would want some light, but the only option from bedside is a switch that turns on the overhead cans, which are BRIGHT, along with the standing lamp. Your bedmate would not be amused! That light switch was only on one side of the bed. If your partner got up, they had to do so in the dark.

Then there was the desk…which didn’t exist! Instead, there was a small rolling table sitting under a narrow shelf along the wall where you would expect to find the dresser/desk furniture. To use it, you had to sit on the bed. There was a desk-style chair, but it was in the corner of the room, and wouldn’t fit between where the table was and the bed. There wasn’t much in the way of storage area for your clothes either. The Hampton Inn didn’t have a desk, but at least it had a small table, more like a cafe table you might find at a coffee shop than a desk, and a chair to go with it. There was also an lounge chair with a smallish computer table that you could move over your lap to work from, or eat from.

There’s a concept called User Centered Design, wherein attempts are made to create designs that center around the way a user would interact with the product. This often involves focus groups looking at the design, or even visiting a mock up, and giving their opinions on what they see. This isn’t limited to hotel rooms, but can (and should) be used in any type of device or product that will be used by the public.

An example from my previous life…I chaired a series of meetings between some large customers and a computer company wherein the customers were introduced to a new cartridge tape drive that was revolutionary. I expected the customers to be thrilled when they saw the product. But they weren’t. The individual units were 1 meter in height, roughtly tabletop height. The customers pointed out that computer operators would put stuff on a surface that height. The engineers who designed these devices only put one thing on that surface…the power button. How long do you think it would have taken before someone accidentally powered off a drive while it was being used? I should point out that I had not seen the actual drive myself before this set of meetings, so can’t say if I would have thought of this problem, but I’d like to think I would have. Anyway, as a result of these meetings, the power button was moved prior to general availability of the drive. Several other design elements were changed too.

Anyway, I thought I’d share these observations with you all since I had a lot of time to think about them. If what I observed helps you avoid a room with bad design, all the better. And I hope you got a chuckle out of all this.

Now, on to the news.

Government and Science

NPR reports that one of the many cuts made by the Department of Government Efficiency (DOGE) was the removal of the climate.gov website. This contained extensive records on climate, which inconveniently showed proof of climate change. Since the current administration has called climate change a “hoax”, such data would undermine the message they wanted to send. The people who worked on this site were laid off, being deemed unnecessary since the website was going away.

Well, some of those people recreated the climate.gov website, now called climate.us. Most of the data on the original site is still available, but is buried on a variety of government servers. All it took to rebuild this site was around $280,000 in crowd-sourced funds and a small team of researchers. Among other things, this proves the closure of the climate.gov site wasn’t about cost or efficiency, but about removing easy access to information that was contrary to the message the administration wanted to send.

Thanks to Herb for bringing this to my attention, and to Denise Middleton who posted about this on the Slack platform.

In a similar vein, the Administration is upset about a chapter about climate science in an educational guide for judges. The guide was developed by the National Academies of Sciences and covers many aspects of science. Such a guide is available to judges to provide them guidance on scientific topics they might not be familiar with when cases come before them that require some scientific background. Again, the attack isn’t based on science contradicting climate change, but on idealogical issues.

All these attacks on science are having a toll, on many levels. Neil deGrasse Tyson has some thoughts on the unintended consequences of the Administration’s massive cuts to science funding. Recovering from these cuts won’t be as simple as restoring funding. Researchers have gone to other countries. PhD candidates are no longer coming to US institutions to do their research. The government seems to think private industry will take up the slack, but they need to make a profit to survive. Any funding provided by the government will most likely require results that meet the agenda of the current administration. This damage has already been done. Sobering.

Several states, including California, have looked at making Daylight Savings Time permanent. California voters approved a referendum on this several years ago. However, federal approval is required for any state to change their Daylight Saving Time rules.

Earlier this month, the House of Representatives passed a bill which would make daylight savings time permanent. It must till get through the Senate. Is this really a scientifically backed improvement? Would year-round standard time be better? The answer isn’t all that simple.

Climate

The big news for California over the past few weeks/months has been the development of a strong El Nino. What will this mean for the coming months? More rain? Less? The general media has coined the term “Super El Nino”, but this hasn’t been adopted by the scientific community. It makes for catchy weather promos (“tune in at 11:00 to see what to fear next!”) but isn’t an official category. Here are the answers to these questions, and more.

In Europe, wildfires have caused over 250,000 people to be evacuated in France and Spain. NASA’s Deep Space Communications Complex, which is near Madrid, was affected by one of these fires. It is too early to tell how much damage was caused. This center is one of three that are used to communicate with probes, including Voyager 1. Workload has been transfered to the other two, so no ongoing missions are directly affected.

Technology

Where better than Silicon Valley for a museum dedicated to technolgy than the place where much of it has been invented. The Computer History Museum in Mountain View attempts to chronicle this technology, and they just received a huge donation towards that end.

Artificial Intelligence

This week, OpenAI said a test model of theirs had “escaped” its test environment, broken into a real, outside company’s servers, all in an effort to “ace” an internal cybersecurity evaluation. In other words, it cheated on a test, looking for answers outside its sandbox. This wasn’t a single step effort either. It was a complex series of actions taken by the model to find flaws in the security of its own environment. How did this happen? Read the article.

Space and Astronomy

This article is a few years old, but I learned of it while on my trip back east. I stayed with a friend who happens to know the CEO of Near Space Corporation and she told me of this article about the company and their involvement in a small corner of the very complex project of getting to Mars. I always wonder about the reasons some people form the niche companies they start and how their success contributes to a much larger project. This is such a story.

We often link to Phil Plait, the Bad Astronomer, who discusses current topics from astronomy. Here, he talks about the Vera C. Rubin Observatory which just came online, and what it will mean to the search for asteroids, comets, and many other types of objects in the Universe.

Citizen science projects are pretty neat. They offer the general public a chance to help with data analysis. Such a project has resulted in the finding of more than 3,000 brown dwarfs near to us. That’s a lot!

There are two rocky planet discoveries near to earth in the news this week. The first one, GJ3378b, orbits a red dwarf just 25 light years from us. For comparison, the Milky Way is around 100,000 light years across. It isn’t clear if GJ3378b has an atmosphere, but it is rocky and will be studied further.

The other one, LHS1140b does have an atmosphere, orbits its star in the habitable zone (also called the Goldilocks Zone) and is also rocky. It is cooler than Earth, but larger in size and mass. It seems to have a helium-rich atmosphere.

Finding earth-sized planets at the right distance from their stars is not easy, given their small size and the distances between us. Most of the exoplanets found so far are gas giants, like Jupiter, which are easier to detect.

Have a great week in Science!

Greetings science fans!

I was visiting friends in Seattle over the weekend and had the good fortune to get an impromptu tour of the Nuclear Physics Laboratory at the University of Washington, home to two of the most ambitious experiments to study dark matter.

The first is ADMX, the Axion Dark Matter Experiment. The QCD axion, originally proposed in the late 1970s to solve a problem in particle physics, was quickly identified as a promising dark matter candidate. ADMX searches for axions the way you might search for a radio station: using a strong magnetic field and a cold, precisely tuned microwave cavity, it scans across frequency bands that correspond to the possible masses of the particle, waiting for axions to convert into detectable photons. It is patient, methodical work, looking for a whisper from a particle that makes up most of the mass of the universe, but has never been directly detected.

The second is the LEGEND project, which is hunting for something equally profound: neutrinoless double-beta decay, a process that would occur only if neutrinos are their own antiparticles. If observed, this would demonstrate that the neutrino is its own antiparticle and could be the key to understanding how our universe formed, transforming how scientists understand matter, mass, and the evolution of everything we can see around us. LEGEND-200 is currently taking data at the Gran Sasso National Laboratory in Italy, while the next stage, LEGEND-1000, with a total detector mass of one ton of enriched germanium, is under preparation. The scale of these collaborations is genuinely humbling – hundreds of researchers across dozens of institutions, all chasing a signal that may take decades to find, if it exists at all. Seeing it up close is a reminder of what big team science looks like when the question is big enough.

And July 20, is itself a good day to think about humanity’s long patience with the cosmos. Fifty years ago, NASA’s Viking 1 touched down safely on Mars at 7:53 a.m. EDT, giving humanity our first ground-level view of the Red Planet. The twin robotic spacecraft conducted experiments to detect life and, although they didn’t provide conclusive answers, sparked a revolution in space study. This week is a great opportunity to learn about some amazing spacefaring exploits that are only possible through persistent exploration. Wednesday’s Astronomy on Tap, Thursday’s After Dark at the Exploratorium, and Saturday’s gravitational wave talk at the San Jose Astronomical Society each offer a different window into that same spirit of slow, cumulative discovery.

Science at its best is an act of extraordinary patience.

Lili Galilean
13 July 2025

Greetings, fellow observers of the physical world!

As we cross the halfway mark of July 2026, the global temperature isn’t the only thing hitting a fever pitch. With the 2026 World Cup barreling through its high-stakes knockout rounds, the high-intensity drama on our screens is matched only by the invisible, brutal engineering tournament happening directly beneath the players’ cleats.

This week, we are pulling our focus out of the clouds to examine two very different kinds of competitive arenas: a physical tournament of highly engineered grass, and Big Tech’s brand-new multi-agent “idea tournaments” designed to automate hard science. Grab a cold drink—it’s time to break down the mechanics of the game.

1. World Cup Turfs: Engineering a Unified Pitch

If you’ve been watching the World Cup matches over the last few weeks, you aren’t just looking at elite athleticism—you’re looking at a masterclass in composite materials science.

The logistical nightmare of a 48-team tournament spread across sixteen stadiums means playing in radically different environments. How do you make a pitch in the high altitude of Mexico City perform identically to one in the heavy humidity of Miami? You stop treating grass like a plant, and start treating it like a reinforced industrial composite.

To survive the intense shear stress of world-class athletes sliding, pivoting, and carving into the earth, turfgrass scientists had to completely re-engineer the field. First, uniform sod is grown on giant sheets of plastic so the root structures remain entirely intact during rapid transit and immediate stadium installation. Once laid down over a 14-inch bed of sand and modular plastic drainage cells, the natural grass is literally stitched together with 2.5 inches of synthetic fibers.

This hybrid root matrix acts exactly like rebar in concrete. Under normal circumstances, an elite athlete making a sharp, sudden turn would rip up a massive divot of earth. In this composite matrix, the synthetic threads catch and anchor the natural roots, preventing the pitch from tearing apart and ensuring uniform ball-bounce physics regardless of the local weather. It is a literal physical tournament of tensile strength and root-binding kinetics.

2. The AI Faculty: Co-Scientist and the Multi-Agent tournament

Meanwhile, in the digital realm, Google DeepMind has brought a very different kind of tournament structure out of the lab. Formally graduating from a research project to a full peer-reviewed Nature paper, DeepMind officially introduced Co-Scientist.

Instead of relying on a human to feed a single prompt to a chatbot, the framework operates like a hyper-accelerated academic department populated by a collaborative coalition of specialized AI agents:

• The Generation Agent: Pitches literature-grounded hypotheses and research focus areas.
• The Reflection Agent: Acts as a piece-by-piece peer-reviewer, tearing ideas apart for correctness and novelty.
• The Ranking Agent: Runs an automated “idea tournament,” scoring surviving theories Elo-style using AlphaGo-inspired logic.

The system is already showing real-world promise; in lab-validated trials published in its Nature debut, Co-Scientist successfully identified novel therapeutic targets for liver fibrosis and discovered unprompted combination therapies to combat acute myeloid leukemia.

3. The SciSchmooze Skeptical Twist: Putting AI on a Math Leash

This all sounds incredibly revolutionary—until you look at the compute budget. DeepMind acknowledges that Co-Scientist’s energy is spent largely on verification, ruthlessly cross-checking its own agents against structured databases like ChEMBL and UniProt to prevent confident hallucinations. As a recent Labcritics analysis points out, candidate generation is getting cheap, but verifying physical reality remains expensive.

The tech industry is running into a sharp architectural wall: Large Language Models (LLMs) excel at processing scientific text, but face steep structural limitations when acting as the primary calculator for physical or chemical properties.

A prominent viewpoint of Yann LeCun (a Turing Award-winning AI pioneer and Executive Chairman of AMI Labs) is that text is too thin a signal for true intelligence. Because LLMs merely predict the next word, they possess no causal world model; they excel at mapping statistical correlations in language, but lack an internal physics engine to understand the underlying mechanics of cause and effect. As LeCun bluntly puts it, “they do not understand the physical world.” Their linguistic fluency simply masks an inability to compute first-principles math or balance chemical reactions.

This absence of physical grounding is also central to a critique by UCL physical chemistry professor Peter Coveney and Science Museum Group director Roger Highfield in Frontiers in Physics. In their paper, “AI needs physics more than physics needs AI,” they warn that modern frontier architectures rely on trillions of parameters but lack uncertainty quantification, provide no mechanistic insights, and fail to capture basic scientific laws.

This reality check explains the industry’s rapid pivot from pure chatbots toward Large Quantitative Models (LQMs), highlighted by Google Cloud’s recent rollout of scientific tools from SandboxAQ—an independent Alphabet spinout that claims to operate at the intersection of AI, quantum mechanics, and physical science.

Unlike text-trained LLMs, LQMs are explicitly engineered directly on physical equations and laboratory data. The new enterprise paradigm splits the labor: a frontier LLM handles the natural language interface and literature synthesis, but it completely offloads the rigorous physics—such as calculating exact molecular adsorption energies on a metal catalyst surface—to a rigid, deterministic engine like Sandbox’s AQCat.

Here lies our healthy dose of SciSchmooze skepticism: When an AI tournament crowns a top-ranked hypothesis, does it expand human insight—or just scale up an automated checklist? Just like the high-stakes engineering playing out on the grass, the ultimate test for this quantitative league is simple. Can it deliver a truly paradigm-shifting material in the physical world, or will it just churn out faster, automated spreadsheets?

Structurally yours,
Lili
