Phys.org / Quick action needed as the world is set to get hotter than we hoped
Global temperature rise is set to cross 1.5°C, likely within the next few years, pushing climate risks and impacts to increasingly dangerous heights. But it is still possible to bring temperatures down and achieve the global ...
Phys.org / Weak sea-surface temperature gradients may fuel stronger tropical cyclones
The fact that the ocean gets colder as you go deeper is fairly intuitive, but a similar gradient exists along the surface of the ocean, even at scales of 1 kilometer to tens of kilometers. A new study, published in the Proceedings ...
Tech Xplore / Why did your robotaxi stop? New system helps predict self-driving car mistakes
Self-driving cars are often controlled by deep learning models that sometimes fail in unexpected situations. For instance, the car might inexplicably brake and block the path of an oncoming emergency vehicle. A human driver ...
Phys.org / New model explains how bacterial promoter elements set gene activity and regulation
Bacterial promoters are DNA sequences that recruit RNA polymerase to initiate transcription, primarily through two elements called −10 and −35. However, the contributions of these elements to promoter evolution and regulation ...
Phys.org / Rare train of Pacific cyclones fueled by historic El Niño
Two powerful hurricanes and a strengthening tropical storm on Wednesday were churning through the Pacific Ocean, where waters were being warmed by a historically strong El Niño climate episode.
Phys.org / US politics is not the world's template for polarization, experts warn
Common global narratives about political polarization are skewed because of an overreliance on literature about the U.S., leaving governments unprepared to tackle the problem at home. In new research led by King's College ...
Medical Xpress / DR Congo Ebola vaccine trials to begin by November: WHO
Trials for three potential vaccines against the Ebola strain that has killed thousands in the Democratic Republic of Congo should begin by October or November, the World Health Organization said Wednesday.
Phys.org / When biology inspires mathematics: Hidden symmetries explain why widely used evolutionary methods can give false answers
Why do some groups of organisms contain thousands of species while others have only a handful? Evolutionary biologists have spent decades trying to answer this question using mathematical models that estimate how biological ...
Phys.org / Iguanodon shinbone growth may be first evidence of an infected skin ulcer in a dinosaur
Fossilized bones can reveal a wealth of details about animals, including their size, appearance, what they ate and any injuries they may have suffered. In a paper published in the journal Royal Society Open Science, researchers ...
Tech Xplore / Two molecules work together to seal microscopic gaps in perovskite solar cells
A research team has developed a dual-molecule passivation technology that simultaneously improves the efficiency and stability of inverted perovskite solar cells. The research is published in the journal ACS Applied Materials ...
Tech Xplore / Uber says it is laying off 'about 10%' of its workforce worldwide
Ride-hailing giant Uber will lay off about 10% of its staff as part of "significant organizational changes," CEO Dara Khosrowshahi said in a message to employees released Wednesday.
Phys.org / Cluster's final reentry strengthens data for safer, more sustainable satellite design
The Cluster mission danced its final dance as Tango reentered the atmosphere Sept. 1 at 11:30:31 p.m. CEST. The end of the Cluster mission in 2024 marked the start of the reentry data-collection campaign. After four targeted ...
