Combining solar power production with agriculture can significantly boost crop yields, conserve water and generate low-carbon electricity for areas particularly vulnerable to climate change, a new study has shown.
UW oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring
Researchers produced 3D-printed, semiconductor-free logic gates, which perform computations in active electronic devices. As they don’t require semiconductor materials, they represent a step toward 3D printing an entire active electronic device.
A trio of Harvard researchers has developed a new 3-D pictorial language for mathematics with potential as a tool across a wide spectrum, from pure math to physics.
The NASA/ESA Hubble Space Telescope has captured the most detailed image yet of a close neighbour of the Milky Way — the Triangulum Galaxy, a spiral galaxy located at a distance of only three million light-years. This panoramic survey of the third-largest galaxy in our Local Group of galaxies provides a mesmerising…
DURHAM, N.C. -- Glioblastoma brain tumors can have an unusual effect on the body’s immune system, often causing a dramatic drop in the number of circulating T-cells that help drive the body’s defenses. Where the T-cells go has been unclear, even as immunotherapies are increasingly employed to stimulate the body’s…
A report, released today, states that ice loss from Greenland and Antarctica has increased fivefold since the 1990s, and now accounts for a quarter of sea-level rise.
[EDITOR'S NOTE: In marking this year's 25th anniversary of Edge , we are presenting original lectures from eminent scientists and other thinkers in the empirical world who are changing the way we think about science and our place in the world.]
Investigation to find a better rational approximation for pi. Can we get out more digits than we put in? Chance to win a prize if you can do bette
The first time Vayu Maini Rekdal manipulated microbes, he made a decent sourdough bread. At the time, young Maini Rekdal, and most people who head to the kitchen to whip up a salad dressing, pop popcorn, ferment vegetables, or caramelize onions, did not consider the crucial chemical reactions behind these concoctions.
Mitchell J. Feigenbaum , a mathematical physicist whose groundbreaking work on deterministic chaos influenced fields ranging from cardiology to cartography, died in New York City on June 30 at the age of 74. Feigenbaum was the Toyota Professor and director of the Center for Studies in Physics and Biology at…
President Joe Biden has announced that Ingrid Daubechies , James B. Duke Distinguished Professor Emerita of Mathematics , will receive the National Medal of Science in 2025. She is being honored for her pioneering work on signal processing.
In this topic page, we explore data on loneliness and social connections and review available evidence on the link between social connections and well-being.
Founded in 1920, the NBER is a private, non-profit, non-partisan organization dedicated to conducting economic research and to disseminating research findings among academics, public policy makers, and business professionals.
We are devastated to report that Big Basin, as we have known it, loved it, and cherished it for generations, is gone. Early reports are that the wildfire has consumed much of the park’s historic facilities. We do not yet know the fate of the park’s grandest old trees.
The “forever chemicals” found in the Cape Fear River were detected through a non-targeted testing method developed at UNC-Chapel Hill that broadens researchers’ abilities to identify the hazardous compounds.
Human neurons have a lower density of ion channels than expected, compared to neurons of other mammals, according to a new study. The researchers hypothesize that a lower channel density may have helped the human brain evolve to operate more efficiently.
Is it true that two pieces of metal will permanently join together if they touch in a vacuum? In theory, yes.
The ESA/JAXA BepiColombo mission has captured its first views of its destination planet Mercury as it swooped past in a close gravity assist flyby last night.
Human anatomy still has a few surprises in store for us: researchers at the University of Basel have discovered a previously overlooked section of our jaw muscles and described this layer in detail for the first time.
AUSTIN, Texas — Using generative artificial intelligence, a team of researchers at The University of Texas at Austin has converted sounds from audio
The NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 observed Saturn on 20 June 2019 as the planet made its closest approach to Earth this year, at approximately 1.36 billion kilometres away.
In an unusual trial, Stanford Medicine researchers found that a patient’s belief that they had received ketamine, even if they didn’t, could improve their depression.
Once we emit about 1000 gigatons of carbon, much of the massive ice sheet will melt irreversibly. We’ve emitted 500 gigatons so far.
Researchers offer first proof that Ultraviolet C light with a 222 nm wavelength — which is safer to use around humans — effectively kills the SARS-CoV-2 virus.
Myth of the Brown Recluse: Fact, Fear, and Loathing Rick Vetter Department of Entomology, University of California, Riverside, CA
Cellular (T cell) immunity against SARS-CoV-2 is likely to be present within most adults six months after primary infection, a new pre-print on bioRxiv suggests.
