These tropical trees breathe at night to survive drought

Plants have evolved several ways to use sunlight to turn water and carbon dioxide into energy-rich sugars and oxygen (photosynthesis). But when water becomes scarce, that process can become much more difficult. Researchers led by Wolfram Weckwerth at the University of Vienna have now uncovered how one especially water efficient…

First stellar stream beyond the Milky Way could reveal dark matter

A faint ribbon of stars can be seen stretching across the galaxy in the image above. Known as a globular cluster stellar stream, this type of structure preserves clues about its past motion and evolution. By studying these streams, astronomers can learn more about how galaxies developed and how dark…

Why Viking museums still can’t escape the warrior myth

If you visit Scandinavia you are likely to find yourself at an exhibition about Vikings. There are many to choose from. The National History Museum in Denmark’s capital, Copenhagen, houses a major permanent exhibition on Viking. The Swedish History Museum in Stockholm boasts the largest Viking Age exhibition in the…

Stonehenge’s 6-ton altar stone may have traveled from Scotland by glacier

Researchers studying the origins of Stonehenge’s Altar Stone have proposed a new possibility for how the enormous rock began its journey from Scotland to southern England. A team from Sheffield Hallam University and Curtin University, Australia, analyzed ancient ice movement and found that glaciers during Britain’s last ice age may…

The LHC just ruled out another hiding place for quantum black holes

Physicists at UC Santa Barbara have pushed the search for microscopic black holes at the Large Hadron Collider (LHC) at the European Center for Nuclear Research (CERN) into new territory. These hypothetical black holes would be extraordinarily small and short-lived. If they could be produced at the LHC, their existence…

The Solar System chose fire over ice from the very beginning

The earliest stages of planet formation may have been far more selective than scientists once realized. As the young Solar System began assembling solid objects such as planets, moons, and protoplanets, two major types of material were available. One was chondrules, millimeter-sized pieces of rock formed at high temperatures. The…

One of America’s largest reservoirs just hit a record low

Snow drought and unusually warm conditions across the Colorado Basin in 2026 sharply reduced water flowing into major reservoirs across the U.S. West. By summer, the effects of the weak 2025-2026 mountain snowpack in the Upper Colorado Basin had reached Lake Powell. With far less snowmelt than usual feeding the…

This new drug could break cancer’s resistance to treatment

Researchers at Baylor College of Medicine have developed an experimental drug called CS18 that may help cancer treatments work against tumors that have become resistant to therapy. The study, published in Science Advances, provides early evidence supporting further investigation of CS18 as a possible future cancer treatment. “Therapeutic resistance is…
