The largest, most advanced rover NASA has sent to another world touched down on Mars Thursday, after a 203-day journey traversing 293 million miles (472 million kilometers).

Odor-producing glands and tissues in bats may play a prominent role in mating behavior.

Researchers identified new therapeutic targets for gastrointestinal stromal tumors (GISTs) that could lead to new treatment options for patients.

Psychologists suggest a link between DNA and traits beneficial to bonding and satisfaction in first years of marriage.

Latest discovery could improve development of future stem cell therapies and cancer treatments.

In one species of ants, workers duel to establish new leadership after the death of their queen. While these sparring matches stretch for more than a month, changes in behavior and gene expression in the first three days of dueling can accurately predict who will triumph, according to a New York University study published in the journal Genes & Development.

Researchers show that levels of specific antibodies developed in the immune response may influence COVID-19 outcomes in both children and adults.

Researchers have developed advanced explainable artificial intelligence (AI) in a technical tour de force to decipher regulatory instructions encoded in DNA.

As climate change takes hold across the Americas, some areas will get wetter, and others will get hotter and drier. A new study of the yellow warbler, a widespread migratory songbird, shows that individuals have the same climatic preferences across their migratory range.

A technique for controlling the orientation of manufactured DNA shapes now removes one of the last barriers for the combination of molecular devices with conventional semiconductor chips.

A unique brain protein measured in the blood could be used to diagnose Alzheimer's disease decades before symptoms develop, according to new Edith Cowan University (ECU) research.

Eastern newt populations in the northeastern United States and southeastern Canada are at greatest risk of infection with a new skin-eating fungus, Batrachochytrium salamandrivorans (Bsal), according to a new study.

One day physicians may be able to look at an African American's skin color and, with the help of other determinants, know if prescribing vitamin D supplements would lower that person's risk of getting cancers of the prostate, colon, rectum or breast.

A child's first influenza infection shapes their immunity to future airborne flu viruses - including emerging pandemic strains. But not all flu strains spur the same initial immune defense, according to new findings published today. The results are relevant to the COVID-19 pandemic, according to the senior author, who says they may explain age-based distributions of SARS-CoV-2 disease severity and...

New observations of the first black hole ever detected have led astronomers to question what they know about the Universe's most mysterious objects. The research shows the system known as Cygnus X-1 contains the most massive stellar-mass black hole ever detected without the use of gravitational waves.

Scientists have created new proteins that adopt one of the most complex folds known to molecular biology. These pore-like barrel-shaped proteins spontaneously fold into their intended structures and embed into lipid membranes. Although the scientists drew inspiration from proteins found throughout the living world, they arrived at sequences that differ from any known before. The resulting compact...

Scientists uncover for the first time how the body's energy makers are made. An international team of researchers report an insight into the molecular mechanism of membrane-tethered protein synthesis in mitochondria. This is a fundamental new understanding of how the human mitoribosome functions and could explain how it is affected by mutations and deregulation leading to disorders like deafness...

Scientists have used a technique to grow bile duct organoids - often referred to as 'mini-organs' - in the lab and shown that these can be used to repair damaged human livers. This is the first time that the technique has been used on human organs.

The gut microbiome is an integral component of the body, but its importance in the human aging process is unclear. Researchers have identified distinct signatures in the gut microbiome that are associated with either healthy or unhealthy aging trajectories, which in turn predict survival in a population of older individuals.

Researchers have identified a new class of mutations that help bacteria develop antibiotic resistance. In a study of E. coli, they discovered that mutations to genes involved in metabolism can help bacteria to evade the toxic effects of several different antibiotics.

Viruses are the most numerous biological entities on the planet. Now researchers have identified over 140,000 viral species living in the human gut, more than half of which have never been seen before.

People tend to listen to big talkers, whether they are women or men. Still, more women prefer not to use assertive language, according to a new study. Participants in an experiment more often followed advice of people using assertive 'cheap talk,' statements that cannot be verified as true.

The temporary breakdown of Earth's magnetic field 42,000 years ago sparked major climate shifts that led to global environmental change and mass extinctions, a new international study shows.

Often depicted as colorful balloons or clouds, electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of electrons in chemical reactions, it is not only important to know their spatial distribution but also their motion in time. Scientists have now made huge progress in this direction: They successfully...
