JWST hunts for an 'Earth-moon' twin in a habitable zone, but the star has other plans
The moon has played a huge role in the development of Earth. It stabilizes the planet, tempers dramatic climate swings, and possibly even provides the tidal heating that might have led to the first life forms. So it's natural we would want to find a similar Earth/Luna system
An unprecedented Antarctic heat wave hit in the dead of winter—what it signals for the decades ahead
In the middle of the Antarctic winter, during months of darkness when temperatures often dip below −30°C, the continent warmed dramatically. In July and August 2024, temperatures in parts of East Antarctica rose by up to 28°C above average and stayed high for more than two

Beyond city limits: New ecology framework links urban, rural and wild landscapes
As cities sprawl into suburbs and exurbs, the distinction between urban areas and the countryside has become increasingly blurry. A new paper published in npj Urban Sustainability proposes that many modern landscapes can be managed more holistically when they are understood as
Machine learning offers faster, more reliable analysis of Fermi surfaces in search of spintronic materials
The search for next-generation electronic materials often starts with studying the Fermi surface, which serves as a map of a material's electronic structure. Its shape varies with crystal structure, composition, and electronic band arrangement, directly impacting properties
Specially designed material combines light and electricity to remove PFAS from water without harmful byproducts
Researchers at Clarkson University have reported a breakthrough in tackling per- and polyfluoroalkyl substances (PFAS), a group of widely used "forever chemicals" that are difficult to remove from water and have raised growing environmental and public health concerns. The

Why stars spin down, or up, before they die
From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they "spin down." The sun's total angular momentum has declined as material is gradually blown off at the surface as solar wind. By observing this, astronomers have
Scrapped inheritance tax linked to stronger growth in private firms with heirs, shows study in Sweden
After Sweden removed inheritance and gift taxes in 2005, private firms with potential family successors grew faster, invested more, and paid higher corporate taxes than firms without natural heirs, according to a new white paper from the Stockholm School of Economics. The study
Detailed DNA repair snapshots reveal how BRCA-linked cancer cells may survive
Scientists have captured the most detailed structural images to date of a specific type of protein's DNA repair process, a finding that could reveal ways to inhibit the effects of BRCA1 and BRCA2 mutations that heighten the risk for breast, ovarian and other cancers.
Informal educators get a powerful new way to speak their mind and boost their skills
Few elements of our culture are as firmly established in the 21st-century Western zeitgeist as the fact that teachers are underappreciated and poorly paid. That goes double for informal educators—those who work outside the confines of diploma- or degree-granting institutions.
Small differences in cell structures called microtubules determine how well cancer drug performs
