When the Atlantic creeps closer: Study helps vulnerable Massachusetts peninsula prepare for rising sea levels‎

On many days, Apple Street looks like a picture postcard of New England. Oaks shade a time-worn stone wall, boat sheds loll behind granite outcrops. But during storms, this pretty lane only a few feet above sea level can turn into a moat, cutting off an emergency shortcut that ambulances count on when Essex's main street floods several times per year.

Mission for ancient climate clues beneath Antarctic ice gets underway‎

If it were to melt completely, the vast West Antarctic Ice Sheet (WAIS) holds enough ice to raise the global sea levels by 4 to 5 meters (13 to 16 feet).

The Ivies can weather the Trump administration's research cuts. Public universities that have the most to lose‎

Most of the media coverage of the federal government's recent cuts in federal research money for universities has focused on its effects on a handful of elite Ivy League universities, such as Harvard, Columbia and Cornell.

Dual substitution induces room-temperature ferromagnetism and negative thermal expansion in BiFeO₃‎

Using a dual-cation substitution approach, researchers at Science Tokyo introduced ferromagnetism into bismuth ferrite, a well-known and promising multiferroic material for next-generation memory technologies. By replacing ions at both the bismuth and iron sites with calcium ions and heavier elements, they modified the spin structure and achieved ferromagnetism at room temperature. Additionally, negative thermal expansion was observed. This ability to engineer magnetism and thermal expansion in a multiferroic material aids in realizing future memory devices.

Examining trends and factors of urban shrinkage in medium-sized cities‎

Cities do not always grow in a straight line. Like living organisms, they experience growth, maturity, and sometimes decline. This decline, known as urban shrinkage, is a natural phase in the urban life cycle. It is common in industrialized cities, marked by aging social infrastructure resulting from population decline.

With feathers into the afterlife: New results on the Bad Dürrenberg shaman burial‎

The approximately 9,000-year-old grave of the shaman from Bad Dürrenberg (Saalekreis district) is one of the most spectacular finds in Central European archaeology. Excavated under considerable time pressure in 1934, subsequent investigations at the site from 2019 onwards allowed for the recovery of remains of the burial pit, which were then removed as a block and examined under laboratory conditions. These investigations revealed a series of new insights. Microscopic evidence has now been obtained of feathers that likely belonged to an elaborate headdress.
