Phys.org / Leaf forces help steer stomata as young plants grow, experiments reveal
Scientists have uncovered how the interplay between cell shape and mechanical stress influences the orientation of stomata (microscopic pores on the leaf surface) during early plant development.
Phys.org / Record wildfire losses rocked 2025 even as global burned area neared all-time lows
A new analysis of global wildfire activity in 2025 reveals the world experienced some of the most destructive and deadly fire events in recent history, despite the second lowest area burned since 2002. It highlights a continued ...
Phys.org / Bacteria uncover distinct strategy to import rare sugar polymers, crystal structures show
Even though sugars are often framed as simple sources of energy, they also serve as structurally complex and functionally diverse molecules that mediate interactions between organisms. Among these, β-1,2-glucans, which are ...
Phys.org / Inside Europe's largest Copper Age tomb, children's bones expose an ancient health crisis hidden for 5,000 years
Nearly 5,000 years ago, respiratory infections, possibly including tuberculosis, were ravaging the children buried at Camino del Molino (CMOL), Spain. The massive circular burial cave carved into rock is Europe's largest ...
Phys.org / Quantum light gives a 20-fold boost to ultrafast laser processes
Nonlinear interactions between light and matter are at the heart of some of the most powerful tools in modern optics, but pushing these processes to their limits has long been hampered by a fundamental constraint: the stronger ...
Phys.org / Evidence of cosmic-ray acceleration from a nearby supernova remnant
Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football (soccer ball) being kicked ...
Phys.org / Pulsar wind nebula inside supernova remnant explored with Chandra
Astronomers from the George Washington University (GWU) in Washington, DC, and elsewhere have employed NASA's Chandra X-ray spacecraft to observe a pulsar wind nebula inside a supernova remnant known as CTA 1. Results of ...
Phys.org / Rainfall near 700 mm marks turning point in ecosystem nitrogen retention
In a study published in Nature Geoscience, a research team led by Prof. Liu Lingli from the Institute of Botany of the Chinese Academy of Sciences (IBCAS) has identified a mean annual precipitation (MAP) threshold of approximately ...
Phys.org / Nanofiber implant delivers three drugs, doubles survival in glioblastoma mice
Researchers with the University of Cincinnati and Johns Hopkins Medicine developed a potential treatment for brain cancer that uses nanofibers embedded with a combination of drugs that work in concert to target tumors. The ...
Phys.org / A trip to the United Arab Emirates' darkest spot reveals a rare view of the Milky Way
The gleaming skyscrapers and bright lights of the United Arab Emirates draw the eyes of all who travel there, a sign of the Arabian Peninsula nation's rapid, oil-fueled development over the last decades into a major hub for ...
Phys.org / Ohio wall lizards overcame genetic bottleneck through rapid population boom, genomes reveal
Non-native wall lizards living in Cincinnati, Ohio, have thrived against the odds thanks to an ability to expand their population more quickly than any inbreeding-amplified harmful genes could weaken their chances for survival, ...
Phys.org / Saturday Citations: Failure to launch; cellular mortality; heavy weather
Highlights from the last week of May, 2026: A key climate tipping point is disrupting the Arctic Ocean food chain (more of a lowlight, I guess). Scuba-diving tourism may not be the benefit to coral reef systems that we once ...
