Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.

A team of researchers has identified a promising new approach that may one day help to restore vision in people affected by macular degeneration and other retinal disorders.

A new study has found important clues about the roles age, sex, hormonal changes and genetics play in how certain biomarkers for dementia are expressed in the blood, according to a new study.

Scientists have implicated the FOXR2 gene in previously unassociated brain tumor types, with implications for diagnosis, prognosis and treatment.

Using advanced DNA sequence analysis, a research team has discovered that tiny organisms in Brooklyn's highly contaminated Gowanus Canal have developed a comprehensive collection of pollution-fighting genes. This finding suggests the potential of a cheaper, more sustainable, and less disruptive method for cleaning contaminated waterways than the current oft-used dredging operations.

Researchers report an association between urinary incontinence and cardiovascular disease risk in women. The researcher recommend women should be checked regularly for urinary incontinence.

Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? Researchers show that this is not due to the random pull of the planets, but rather the kick they receive from a moving Sun.

A new study suggests the universe may rotate -- just extremely slowly. The finding could help solve one of astronomy's biggest puzzles.

Researchers developed a machine-learning-guided technique to solve complex, long-horizon planning problems more efficiently than some traditional approaches, while arriving at an optimal solution that better meets a user's goals.

A recently created RoboBee is now outfitted with its most reliable landing gear to date, inspired by one of nature's most graceful landers: the crane fly. The team has given their flying robot a set of long, jointed legs that help ease its transition from air to ground. The robot has also received an updated controller that helps it decelerate on approach, resulting in a gentle plop-down.

A study suggests that Homo sapiens may have benefited from the use of ochre and tailored clothing during a period of increased UV light 41,000 years ago, during the Laschamps excursion.

Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these 'polar planets' orbiting a stellar pair.

A new study analyzing data from NASA's Perseverance rover has uncovered compelling evidence of multiple mineral-forming events just beneath the Martian surface -- findings that bring scientists one step closer to answering the profound question: Did life ever exist on Mars?

'Do we see colors the same way?' is a fundamentally human question and one of great importance in research into the human mind. While impossible to answer at present, researchers take steps to answering it using a method that can map the experiences of colors between individuals, including those with colorblindness.

Mycobacteria are the world's most deadly bacteria --c ausing infectious diseases including tuberculosis (TB), which alone kills more than one million people each year. New drugs to fight these infections are desperately needed, as the number of cases of antibiotic-resistant mycobacteria is on the rise. Scientists have now used advanced imaging techniques to provide a detailed look at how a tiny virus, known as a phage, invades Mycobacteria.

Researchers have helped overturn the popular theory that water on Earth originated from asteroids bombarding its surface; Scientists have analyzed a meteorite analogous to the early Earth to understand the origin of hydrogen on our planet. The research team demonstrated that the material which built our planet was far richer in hydrogen than previously thought. The findings support the theory that the formation of habitable conditions on Earth did not rely on asteroids hitting the Earth.

Why does dementia affect more women than men? To help solve this mystery, researchers uncovered a new risk factor: age of menopause onset.

Researchers examined teeth and skulls of 99 extinct crocodylomorph species and 20 living crocodylian species to reconstruct their dietary ecology and identify characteristics that helped some groups persist through two mass extinctions. They discovered that one secret tocrocodylian longevity is their remarkably flexible lifestyles, both in what they eat and the habitat in which they get it.

Researchers have isolated a giant virus, which was named Jyvaskylavirus. The discovery shows that giant viruses are more common in northern regions than researchers have thought. It also illustrates that there are still many structures whose origins and functions have not been properly studied.

A researcher has developed an autonomous driving algorithm for agricultural robots used for greenhouse cultivation and other farm work.
