Gravitational waves could be key to answering why more matter was left over after Big Bang
If researchers can detect Q-balls in gravitational waves, it could help explain why more matter than anti-matter was left over after the Big Bang.
New findings about cluster headaches
Debilitating cluster headaches commonly begin in childhood, but patients are not typically diagnosed until they are adults, according to new research.
Study outlines ways to help children learn forgiveness
A recent study suggests that teaching children to understand other people’s perspectives could make it easier for them to learn how to forgive other people. The study also found that teaching children to make sincere apologies can help them receive for…

A new study finds that older people taking a drug used to treat anxiety and insomnia — nitrazepam — as well as those on antidepressants, are twice as likely to suffer postoperative delirium after hip and knee surgery.
Physical features boost the efficiency of quantum simulations
Recent theoretical breakthroughs have settled two long-standing questions about the viability of simulating quantum systems on future quantum computers, overcoming challenges from complexity analyses to enable more advanced algorithms.
Natural infection and vaccination together provide maximum protection against COVID variants
A combination of vaccination and naturally acquired infection appears to boost the production of maximally potent antibodies against the COVID-19 virus, new research finds.
Devising new meat alternatives with 3D printing — and cocoa butter
No longer just a dream of vegetarians and vegans, fake meat is becoming more widely available in grocery stores and restaurants. And more options are almost certainly on the way. One team has now developed a new combination of plant-based ingredients t…
Early warning signals could help monitor disease outbreaks
New research suggests early warning signals (EWSs) could help in the monitoring of disease outbreaks, such as COVID-19. The study found warnings could be detected weeks earlier than any rapid increase in cases. The findings could help governments and p…
Guidelines may promote over-diagnosis of cow’s milk allergy in infants, study finds
International guidelines developed to help doctors diagnose cow’s milk allergy may lead to over-diagnosis, according to new research. The study found that three-quarters of infants have two or more symptoms at some point in the first year of life which…
MRI’s may be initial window into CTE diagnosis in living; approach may shave years off diagnosis
While chronic traumatic encephalopathy (CTE) cannot yet be diagnosed during life, a new study provides the best evidence to date that a commonly used brain imaging technique, magnetic resonance imaging (MRI), may expedite the ability to diagnose CTE wi…
Impaired-driver sensor could pave the way for safer vehicles
The bipartisan infrastructure bill recently signed into law by President Joe Biden includes a requirement for automakers to install driver monitoring systems that detect intoxicated or impaired drivers. Current systems rely on cameras, which have limit…
Newly discovered fish songs demonstrate reef restoration success
Whoops, croaks, growls, raspberries and foghorns are among the sounds that demonstrate the success of a coral reef restoration project.
Streetwise bees cut corners to find food
Bumblebees waste no time enjoying the beauty of flowers — instead learning the bare minimum about where to land and find food, new research shows.
Fleshing out the bones of Quetzalcoatlus, Earth’s largest flier ever
Though discovered more than 45 years ago, fossils of Earth’s largest flying animal, Quetzalcoatlus, were never thoroughly analyzed. Now, a scientific team provides the most complete picture yet of this dinosaur relative, its environment and behavior. T…
2,700-year-old leather armor proves technology transfer happened in antiquity
Researchers have investigated a unique leather scale armor found in the tomb of a horse rider in Northwest China. Design and construction details of the armor indicate that it originated in the Neo-Assyrian Empire between the 6th and 8th century BCE be…
