The physics behind antimatter is one of the world’s greatest mysteries. Looking as far back as The Big Bang, physics has predicted that when we create matter, we also create antimatter.
Insects react sensitively when temperature and precipitation deviate from the long-term average. In an unusually dry and warm winter, their survival probabilities are reduced; in a wet and cold spring, hatching success is impaired.
His mind might have been set on finding water or on perfecting a song he learned as a chick from his dad. But all of that gets pushed down the to-do list for an adult male zebra finch when he notices a female has drawn nigh.
Stanford Medicine investigators and their colleagues sifted through a jumble of genes implicated in neurodevelopmental disorders and identified dozens of disparate troublemakers with similar effects.
Protecting large swaths of Earth’s land can help stem the tide of biodiversity loss—including for vertebrates like amphibians, reptiles, mammals and birds, according to a new study published in Nature Sept. 27.
A study reveals genetic subtypes, biomarkers, gene and pathway targets for the development of new treatments for this liver disease
Researchers tracked the brain’s dopamine reward system and found – for the first time – this system flexibly retunes toward the most important goal when faced with multiple competing needs.
Researchers discover that heart cells in developing zebrafish start beating suddenly and all at once
Patterns of chemical interactions are thought to create patterns in nature such as stripes and spots. This new study shows that the mathematical basis of these patterns also governs how sperm tail moves.
Our cells have a fleet of 300 molecular machines, called cullin-RING ligases, or "CRLs" for short, that each is capable of triggering destruction of specific proteins for the well-being of our cells.
People who have experienced brain fog, confusion, pain, and extreme fatigue for months or longer after being infected with the COVID-19 virus exhibit different immune and hormonal responses to the virus than those not diagnosed with long COVID.
New research, reported in Nature Ecology & Evolution, (25 September 2023) has for the first time validated at scale, one of the theories that has underpinned ecology for over half a century.
Researchers at the Francis Crick Institute, the University of Cambridge, Imperial College London, the University of Liverpool, the University of Cape Town and UKHSA have uncovered a link between an antiviral drug for COVID-19 infections called molnupiravir and a pattern of mutations in the SARS-CoV-2 virus.
The genetic code of a rare form of kidney cancer, called reninoma, has been studied for the first time.
A team led by researchers at Johns Hopkins Bloomberg School of Public Health and the National Cancer Institute has developed a new algorithm for genetic risk-scoring for major diseases across diverse ancestry populations that holds promise for reducing health care disparities.
Research conducted at Mount Sinai and Yale confirms long COVID is a biological disease by showing blood biomarkers that can predict who has it
A new study shows unprecedented heat is likely to lead to the next mass extinction since the dinosaurs died out, eliminating nearly all mammals in some 250 million years time.
Researchers have unravelled for the first time a fundamental shift in the way American politicians communicate on social media, which helps explain the proliferation of compelling misinformation.
A new objective examination of almost a quarter-of-a-century of ocean acidification research shows that, despite challenges, experts in the field can have confidence in their research.
One result of climate change is that spring is arriving earlier. However, migratory birds are not keeping up with these developments and arrive too late for the peak in food availability when it is time for breeding.

Researchers have identified the threat greenwashing poses to a ‘nature positive’ world, one where environmental decline halts and biodiversity outcomes improve.
MicroRNAs are small molecules that regulate gene activity by binding to and destroying RNAs produced by the genes. More than 60% of all human genes are estimated to be regulated by microRNAs, therefore it is not surprising that these small molecules are involved in many biological processes including diseases such as cancer.
