A completely passive solar-powered desalination system developed by researchers at MIT and in China could provide more than 1.5 gallons of fresh drinking water per hour for every square meter of solar collecting area. Such systems could potentially serve off-grid arid coastal areas to provide an efficient, low-cost…
Harvard researchers at Massachusetts General Hospital find that participating in an eight-week mindfulness meditation program appears to make measurable changes in brain regions associated with memory, sense of self, empathy, and stress.
Dolphin researchers are using Gemma and Google Pixel phones to try to decipher how dolphins talk to one another.
Learn to improve the brightness and clarity of images in your mind's eye. Image Streaming is an easy technique to learn. Is it a cure for aphantasia?
Physicist Francis Perrin sat at a nuclearfuel-processing plant down in the south of France, thinking to himself: “This cannot be possible.” It was 1972.
In our study published in Nature, we demonstrate how artificial intelligence research can drive and accelerate new scientific discoveries. We’ve built a dedicated, interdisciplinary team in hopes of using AI to push basic research forward: bringing together experts from the fields of structural biology, physics, and…
Rickover's famous speech about the distinction between academic (paper) reactors and practical reactors.
Two of the experimental coronavirus drugs, chloroquine, and hydroxychloroquine are a breeze to synthesize. But remdesivir, possibly the most promising candidate, is anything but. It's a royal pain. Here's why.

The good educator insists on exercise, play, and plentiful sleep: "the great cordial of nature."
We’re excited to announce YC Research’s newest project: the Human Advancement Research Community (HARC). This came out of a conversation that started between Alan Kay and me more than a year ago about how to invent future computing technologies; I’m delighted to finally be officially working with him and his group. He…
We share the discovery of 2.2 million new crystals – equivalent to nearly 800 years’ worth of knowledge. We introduce Graph Networks for Materials Exploration (GNoME), our new deep learning tool that dramatically increases the speed and efficiency of discovery by predicting the stability of new materials.
The planetary boundaries framework highlights the rising risks from human pressure on nine critical global processes that regulate the stability and resilience of the Earth
Microsoft and Warner Brothers collaborate to store and retrieve the 1978 'Superman' movie on a piece of glass roughly the size of a drink coaster.
A team led by researchers at UW Tacoma, UW and Washington State University Puyallup has discovered a chemical that kills coho salmon in urban streams before the
Some people claim nuclear fuel is inexhaustible and circular, others say we'll run out soon. We do the math. Turns out, it's roughly as inexhaustible as sunlight.
Very few think the world is making progress. In this article, we look at the history of global living conditions and show that the world has made immense progress in important aspects.
The 2000-year-old scroll discusses music, food, and how to enjoy life’s pleasures.
arXiv’s goal is equitable access to scientific research for all – and to achieve this, we have been working to make research papers more accessible for arXiv…

MIT engineers have flown the first silent, fuel-free “ion plane.” The light aircraft is the first plane to fly with no propellers, turbine blades, or other moving parts.
Solving a longstanding mystery, MIT experiments reveal two forms of turbulence interacting. The new finding may explain heat loss in nuclear fusion reactors.
Something central, very central, is missing in historical accounts of scientific and technological discovery. The discourse and controversies focus on the role of luck as opposed to teleological programs (from telos, "aim"), that is, ones that rely on pre-set direction from formal science. This is a faux-debate: luck…

Stanford researchers have determined that average human body temperature in the United States has decreased since the 1800s.
Our new quantum chip demonstrates error correction and performance that paves the way to a useful, large-scale quantum computer.
