A study claims that the North Pole Dome crater in Western Australia was caused by an asteroid strike 3 billion years ago, but other researchers dispute the proposed age
When major infrastructure projects are built in rural areas, wildlife is often displaced and moved out of the way. This is called mitigation translocation, and it is a globally recognized method for moving animals. However, not everyone applies it the same way, or at all.

When many of us think about how drugs work in the body, we may first think about how a drug gets into the body, such as a pill versus an injection. In the Gellman Group at the UW–Madison Department of Chemistry, researchers are instead thinking about how a drug behaves after it
Pterosaurs, the first vertebrates to fly, would have had more diverse wing shapes than current scientific reconstructions suggest, according to new University of Bristol-led research. The study is published in the journal Paleobiology.
Which farming strategies can help agricultural operations better manage yield risks caused by climate change and fluctuating prices in the agricultural product market? A new study by ZALF published in the journal Agricultural Systems uses model calculations to show that farms
How could we noninvasively distinguish between healthy and cancerous tissue? And how could we increase the speed of wireless communications? These two seemingly unrelated questions may share the same answer: terahertz (THz) light. Spanning frequencies between 0.3 and 20 THz,
In a recent study, Manish Garg, independent group leader at Max Planck Institute for Solid State Research (MPI FKF), succeeded in probing the local properties of bright and dark excitons in the organic superconductor copper naphthalocyanine (CuNc). The findings are published in
A new algorithm could drive breakthroughs in understanding cancer, Alzheimer's disease and other potentially fatal conditions. Researchers from the University of Waterloo developed the machine-learning algorithm, called RNovA, to detect changes in the proteins in human cells.
In romantic relationships, touch is usually considered part of everyday life: a quick back rub while cooking dinner, a hug after a long day at work or a lingering kiss before falling asleep. It's a simple way to show support, express affection and communicate sexual desire.
Curtin University researchers have determined the most precise age yet for the oldest known impact crater on Earth, providing new insight into how meteorite strikes shaped the planet during its earliest history.

Cryo-electron microscopy (cryo-EM) can help scientists determine the three-dimensional structure of proteins in unprecedented detail. Jacques Dubochet, former group leader at EMBL, shared the 2017 Nobel Prize in chemistry with Joachim Frank and Richard Henderson for the
A delivery system that uses lipid nanoparticles to sneak proteins into cells can accomplish the same feat by smuggling therapeutic antibodies, new research has found.
Researchers at Northumbria University have produced new economic evidence demonstrating the significant and growing commercial value of alternatives to animal testing in the U.K., with findings already featuring in parliamentary debate on the issue.
Some insects and microbes develop symbiotic partnerships that become so interdependent they can no longer survive without each other. But how specific are these heritable symbioses? Is it possible for the same species of bacteria to flourish across different species of insect
A new study conducted by scientists at the University of Sheffield in collaboration with researchers from UT Southwestern Medical Center in the U.S. has found a protein that could help guide which cells chemotherapies target. The findings, published in Molecular Cell, open up a
Astronomers using NASA's Hubble Space Telescope have found something they never expected—ultraviolet light from a galaxy that existed just 1.4 billion years after the Big Bang. That galaxy contains tightly clustered young stars that produce ionizing light capable of
Heat is no longer a future climate risk. It is already here.
Researchers have discovered how certain photosynthetic bacteria use a sophisticated quantum mechanism to increase their efficiency when capturing sunlight. The study, published today in the journal Nature Chemistry and led by Professor Jenny Clark, reveals that nature has been

A new optical technique developed by researchers at the University of St Andrews and Adelaide University allows toxic methanol in alcoholic spirits to be detected without opening the bottle. Published in the Journal of Physics: Photonics, this new work offers a powerful new
A lot of things need to go right on a molecular level for immune cells to launch an adaptive response to an infection. B cells can produce different classes of antibodies tailored for specific infections through controlled DNA damage and repair that alter the genetic
Ice formation can damage biological samples, tissues and materials during freezing and thawing. In nature, specialized molecules known as ice-binding proteins prevent ice crystals from growing too large, helping organisms survive in extreme cold. Scientists have long tried to
A McGill University study suggests that diversifying crops and replacing annual wheat with a perennial grain could help protect soil health as climate change brings more variable rainfall. The research is published in the journal Applied Soil Ecology.
The modern Colorado moose is often considered just that: modern—brought to the state by wildlife officials in the late 1970s, preceded by very occasional reports of moose sightings in the 19th and early 20th centuries.
Medications can save lives, yet for some drugs, the concentration in a patient's bloodstream determines whether a treatment is effective or whether harmful side effects may occur. Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, have
