Dietary arginine reduces tumor formation and viral load in mice by boosting key immune proteins.
The Hiroshima blast on Aug. 6, 1945, was one of the most devastating events in human history. Like all nuclear detonations, it created fleeting moments of extreme heat, pressure, mixing and cooling. These conditions can briefly produce materials that could never form under
Drylands soils are being degraded by human activities and climate change, threatening the thin living layers covering their surface, called biocrusts, according to the U.S. Geological Survey. Composed of cyanobacteria, lichens, mosses, algae, fungi and bacteria, biocrusts play
For years, social media companies have faced pressure from users and government watchdogs to stop misinformation from distorting elections, deepening political divisions and undermining Americans' trust in institutions. But what if dramatically reducing people's exposure to
Full-color displays normally require separate red, green and blue light emitters. A team from the University of Osaka and Ritsumeikan University has demonstrated another approach: a single light-emitting layer that produces several colors when electrically powered at room
Our DNA is under constant threat. Chemicals, radiation and the everyday errors of cell division all damage it, and if left unrepaired, this can lead to diseases such as cancer. Cells invest heavily in finding and fixing these errors. A new study from EMBL Heidelberg's Pepperkok
In 1989, the Voyager 2 mission discovered six new moons orbiting Neptune, including five tiny ones that orbit just outside the planet's main rings. Because of their small sizes and locations, these satellites have been difficult to study from Earth. Now, using NASA's James Webb
A collaborative research group led by Hiroshi Daimon, a specially appointed research fellow at the Institute for Molecular Science, National Institutes of Natural Sciences, has developed an "atom-holography microscope" capable of directly observing three-dimensional atomic
Everyday shower habits, such as applying shampoo or pausing the water while washing, are driving up water waste, argues a new study from the University of Surrey.
It’s what’s on the inside that counts The post Earth Is Lumpy as Hell appeared first on Nautilus .
Christof Koch is taking on one of science’s deepest mysteries: how the brain creates conscious experience, or whether it creates it at all. He argues that materialism has yet to solve this “hard problem” and will explore puzzling phenomena such as near-death experiences and
Record-breaking heat waves in May and June led to an estimated 2,877 excess deaths in England, the UK Health Security Agency said Wednesday.
As Mohenjo-daro prospered, the gap between its richest and poorest households actually shrank. Its shared infrastructure, fair trade systems, and lack of powerful royal elites suggest that equality may have helped fuel the ancient city’s success.
As biodiversity declines and many of the UK's most important habitats become smaller and more fragmented, conservation organizations need accurate, up-to-date maps to protect wildlife and restore nature. However, creating these maps by surveying every site on foot is
Evolution, the process through which animals and other living organisms change their inherited traits over time, typically unfolds slowly over thousands or even millions of years. Some species, however, can adapt at a faster pace, particularly when they are isolated from other
A canopy call, a partial photo and DNA revealed a new primate species — one that may already be at risk of extinction.
A compound in rice bran may help calm an overactive gut by reducing the calcium signals that cause intestinal muscles to contract. Ferulic acid suppressed contractions triggered by several chemical messengers in laboratory experiments. The discovery could eventually support new
The University of Glasgow's Small Animal Hospital is the first in the UK to use a treatment for dogs suffering from serious allergic reactions to bee and wasp stings. The treatment, Hymenoptera Venom Immunotherapy (VIT), has now been successfully used on a number of patients,
How much of what you see on social media comes from sources that repeatedly post falsehoods? And if that content quietly vanished from your feed, would you believe anything different months later?
Kauri dieback is one of the most serious threats facing Aotearoa New Zealand's kauri forests. The disease is caused by a soil-dwelling microbe, Phytophthora agathidicida, which infects kauri roots and eventually kills the tree. There is no cure, so finding infected trees early
More than 150 years after Darwin’s finches helped reshape biology, Galápagos plants are exposing another evolutionary surprise. Giant daisies repeatedly developed similar heat-tolerant leaf shapes, but each lineage used a different combination of genes. Researchers also found
