NASA's Webb Space Telescope is finding bright, early galaxies that until now were hidden from view, including one that may have formed a mere 350 million years after the cosmic-creating Big Bang.
Bats have lived with coronaviruses for millennia. Details are still hazy about how one of these viruses evolved into SARS-CoV-2, which causes COVID in humans. Did it go directly from bats to humans or via another animal species? When? And why? If we can't answer these questions for this now-infamous virus, we have little hope of preventing the next pandemic.
The James Webb Space Telescope unveiled its latest image of celestial majesty on Wednesday, an ethereal hourglass of orange and blue dust being shot out from a newly forming star at its center.
‘One size fits all’ guidance could lead to 20m litres of drinking water being wasted each day in UK, scientists sayA recommendation to drink eight glasses of water a day is likely to be excessive for most people, according to scientists.The suggestion has become accepted wisdom and often appears in health guidance. The latest work, however, the most rigorous study to date on water turnover,...
A new study published in Science reports results from the first-ever global field assessment of the ecological impacts of grazing in drylands. An international research team has found that grazing can have positive effects on ecosystem services, particularly in species-rich rangelands, but these effects turn to negative under a warmer climate.
Rice University researchers have engineered a key light-activated nanomaterial for the hydrogen economy. Using only inexpensive raw materials, a team from Rice's Laboratory for Nanophotonics, Syzygy Plasmonics Inc. and Princeton University's Andlinger Center for Energy and the Environment created a scalable catalyst that needs only the power of light to convert ammonia into clean-burning hydrogen...
A team of researchers at the University of Agder's, Center for Coastal Research, working with a colleague at the Institute of Marine Research, both in Norway, has found that when protected areas for lobsters are established in overfished parts of the sea, the lobsters tend to grow bigger. In their paper published in Proceedings of the Royal Society B, the group describes their study of lobsters...
New research led by a team of scientists from The University of Manchester has shown that intensive grassland management impairs the capacity of soils to buffer extreme droughts, which are becoming more frequent and intense.
A study published in Science analyses multiple rocks found at the bottom of Jezero Crater on Mars, where the Perseverance rover landed in 2020, revealing significant interaction between the rocks and liquid water. Those rocks also contain evidence consistent with the presence of organic compounds.
