[Note that this article is a transcript of the video embedded above.] In June of 2022, the level in Lake Mead, the largest water reservoir in the United States formed by the Hoover Dam, reached yet another all-time low of 175 feet or 53 meters below full, a level that hasn’t been seen since the la
Oxygen candles are used as a backup source of breathable air inside refuge chambers, making them ideal for emergency situations underground.

The soleus muscle in the calf can do big things to improve the metabolic health in the rest of your body if activated correctly. Now UH researchers are pioneering the “soleus pushup” which elevates muscle metabolism for hours, even while sitting.

Researchers are hoping that a new, low-cost battery which holds four times the energy capacity of lithium-ion batteries and is far cheaper to produce will significantly reduce the cost of transitioning to a decarbonised economy.
An insidious category of carcinogenic pollutants known as “forever chemicals” may not be so permanent after all. University of California, Riverside, chemical engineering and environmental scientists recently published new methods to chemically break up these harmful substances found in drinking water into smaller…
The ultimate Trip To The Seaside Where Everything Went Wrong.
Psilocybin can be safely administered at doses of either 10mg or 25mg to up to six participants simultaneously.
To grow copper acetate crystals, first prepare a saturated solution by reacting 10 g of scrap copper with 400 mL of white vinegar.
The world produces more food than ever, but the amount of land we use is now falling. This means we can feed more people while restoring wild habitat.
I’ve been talking a lot recently about how quantum algorithms don’t work. But last week JR Minkel, an editor at Scientific American, asked me to write a brief essay about how quantum al…
The replication crisis is a major problem in medicine and social science; we know that a huge fraction of the published literature is outright wrong. But in math we don't seem to have a similar crisis, despite reasonably frequent minor errors in published papers. Why not, and what can this tell us about the fields…
Hunting and habitat loss drove many large mammals in Europe close to extinction. New data shows us that many of the continent’s mammal populations are flourishing again.
Make a square, split each side into two halves, producing four cells. Put a circle into each cell such that it fills it completely. There is a small gap right in the middle of the square. Put a circle there again such that it touches the other four circles. The central circle is obviously inside the square, right?…

In a discovery that has repercussions for everything from domestic agricultural policy to global food security and the plans to mitigate climate change, researchers at UMass Amherst recently announced that the rate of soil erosion in the Midwestern US is 10 to 1,000 times greater than pre-agricultural erosion rates.
Explore the diversity of wildlife across the planet. What are species threatened with? What can we do to prevent biodiversity loss?
false memory implantation in adults is easy (bonus: here's one way to do it)
Stanford Medicine researchers and their collaborators have identified a molecule that staves off hunger post-exercise.
The winner of the 2022 MIT $100K Entrepreneurship Competition was Nona Desalination, which is developing a low-cost, portable water desalination and purification device.
In a proof-of-concept study, researchers from the School of Dental Medicine and School of Engineering and Applied Science shows that a hands-free system could effectively automate the treatment and removal of tooth-decay-causing bacteria and dental plaque.
Researchers from the University of Illinois developed GPU-accelerated software to simulate a cell that metabolizes and grows like a living cell.
Bidding farewell to classic experiments.
Spend enough time in the tech world and you will sooner or later find that itis a common article of faith that comput...
Some claims that test scores don’t predict college success don’t add up.
A study of archival images from Zwicky Transient Facility shows an increase in satellite streaks.
I've started learning about spectrum analysis a long time ago at university, but failed to gain a true insight in how it works under the hood. For me, it was just some magical math formulas I had to memorize and know about. I knew the theory but it didn't really click .
