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 / Supermassive black holes could be the universe's biggest planet nurseries
Supermassive black holes are the largest known black holes in the universe, sitting at the center of most large galaxies. They are sometimes described as cosmic monsters because they feed on surrounding gas and dust when ...
Phys.org / JWST finds a stellar bar in the early universe that breaks all rules
Astronomers using the James Webb Space Telescope (JWST) have discovered a stellar bar in GN20, a massive galaxy seen just 1.5 billion years after the Big Bang. The new paper was submitted to the preprint server arXiv on May ...
Phys.org / A kohl bottle from York may hint at an ancient Egyptian in Roman-Britain
Ancient Egyptians are often depicted wearing black eyeliner, known as kohl, which was stored in small containers. While kohl containers are typically found throughout Egypt and Sudan (Nubia), their presence beyond these areas ...
Phys.org / AI crosses catalyst boundaries to uncover new route for green hydrogen
Discovering new catalysts is one of the central challenges in developing clean-energy technologies such as green hydrogen production. Yet catalyst discovery has traditionally remained confined within individual material families, ...
Phys.org / Researchers teach brain cells to play 'Doom'
Australian researchers have trained lab-grown brain cells on a silicon computer chip to play the nineties shooter game "Doom" and say they are just scratching the surface of what the neurons could be capable of doing.
Phys.org / Hidden tick saliva protein may help stop disease spread at source
Few creatures inspire as much universal dislike as ticks. Though small, these parasites have an enormous impact on human and animal health. Each year, ticks spread viruses and bacteria that infect people, livestock, wildlife, ...
Phys.org / Why many fungicide-treated soybean seeds may boost harvests but not farm profits
Many soybean farmers use seeds treated with fungicides to ward off disease, but the profits from these increased yields might not offset the cost of the treatment in most cases, according to a study published in Scientific ...
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 / 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 / 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 ...
