Planets form from disks of gas and dust around young stars, but the gas needed for growth does not last forever. New observations from NASA's James Webb Space Telescope (JWST) now offer a new view of how this gas escapes ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a promising new way to protect fragile quantum information using nothing but mechanical vibrations—essentially ...

Scientists have recently reconstructed the ancestral karyotype of the banana family, revealing how chromosome numbers decreased stepwise from 17 to 9–11 over evolutionary time.

With the invasive emerald ash borer beetle decimating black ash across North America, according to the U.S. Forest Service, a team led by researchers at Penn State conducted an expansive study of genetic diversity in black ...

Researchers at the University of St Andrews have gained unprecedented insight into marine mammal behavior when they become tangled in fishing nets. In a paper published Aug. 26 in Royal Society Open Science, researchers from ...

Tall trees are generally associated with high-biomass forests. This is particularly true for forests dominated by Sequoia sempervirens (hereafter redwood), the world's tallest tree species. Extreme decay resistance, the ability ...

In a study recently published in Nature Communications, researchers from Berlin, Potsdam, and Jena present a new method for analyzing the epigenome. The machine-learning method identifies differentially methylated DNA regions ...

Astronomers can't see dark matter directly, but they know it's there: Its gravity shapes galaxies and the large-scale structure of the cosmos. In an effort to uncover the composition of this hidden mass, a team at Lawrence ...

The most common scientific approach for thinking about how condensation, freezing and other phase transitions begin is based in classical nucleation theory, which was developed about a century ago. Thousands of experiments ...

Pure water freezes only at around -38°C (-36°F). Tiny mineral dust particles act as so-called ice nucleators—crystallization seeds on which ice crystals form. A research team at Bielefeld University and the University of ...

Weill Cornell Medicine investigators have developed a set of molecular tools to regulate the activity of specific genes in one of the most common classes of intestinal bacteria. The ability to genetically manipulate these ...

A team of scientists from Caltech and Yale University has shown for the first time how to accurately quantify an important quantum phenomenon in metals, called the Kondo effect, for specific real materials. Unlike previous ...
