Reinforced vertebrae allow plunge-diving seabirds to survive high-speed impact

A northern gannet scans the sea for fish from 100 feet (30 meters) in the air. Upon seeing a school, it pitches its body into a nosedive, somehow breaking the surface at 70 miles per hour (113 kilometers per hour) without breaking its neck. This daring maneuver seems to defy the laws of nature, but it's standard hunting behavior for plunge-diving seabirds.

Scientists uncover the 2.3-billion-year-old secret that helped keep Earth habitable

Scientists may have solved a 2.3-billion-year-old mystery about how Earth maintained enough oxygen to support life. Ancient rocks reveal that phosphorus recycling in the oceans created a self-sustaining cycle that helped keep oxygen levels high, even as the planet underwent dramatic environmental changes. The discovery challenges assumptions about Earth's early atmosphere and raises new questions about why complex life took so long to emerge.

Global satellite data reveal widening recovery gap between urban and rural vegetation

A global study has revealed a striking divergence in how urban and rural vegetation respond to climate stress. The study was led by Jin Wu from the School of Biological Sciences, Faculty of Science, and professor Yuyu Zhou from the Department of Geography, Faculty of Social Sciences, at The University of Hong Kong (HKU), with Dr. Zhengfei Guo as the first author.

Measuring wildfire plumes to predict extreme fire behavior

Predicting the unpredictable starts with understanding how extreme wildfires develop and under what conditions. This knowledge is essential to better anticipate and respond to them. To achieve this, firefighter and researcher Marc Castellnou and the GRAF/Bombers Catalonia team measure the atmosphere both inside and outside wildfire plumes.

Vapor-based method creates ultralight aerogels without conventional liquid-based chemistry

Researchers at National Taiwan University (NTU), working across the College of Engineering, College of Medicine and National Taiwan University Hospital (NTUH), have developed a new method for producing aerogels, introducing what they describe as the world's first purely gaseous-born aerogel fabrication platform. The study is published in Nature Communications.

Major cities worldwide are sinking, satellite data reveal

Land subsidence is the gradual sinking of the ground, which can damage buildings, foundations, and drainage and sewage systems, and may increase flood risks. However, information on land subsidence dynamics remains limited, which makes it difficult for policymakers to identify where risks are intensifying and where urgent intervention may be needed. Previous assessments have often used different methods or time periods, or focused only on small numbers of cities, which has made global comparisons difficult.

New light-emitting organic materials could enable deep-tissue bioimaging

Researchers at the University of St Andrews have identified the first examples of a new class of advanced organic semiconductor materials that could one day be used as bioimaging agents, opening up new possibilities for deep-tissue imaging. The study, published in Nature Communications, was led by the Zysman-Colman group in the School of Chemistry at the University of St Andrews in collaboration with the Pal group at Durham University.

New study finds the staffing structure of an audit office improves outcomes

Audit firms rely on partners to oversee audits and client relationships; managers to supervise teams and projects; and staff to perform much of the day-to-day work. The more audit partners and managers are involved in supervising and reviewing audit engagements, the better the audits tend to be, according to new research from the University at Buffalo School of Management.

Primordial helium further confirms our understanding of the Big Bang

In the early moments of the big bang, two elements were forged: hydrogen and helium. Technically, the tiniest traces of light elements such as lithium were produced as well, but nothing of consequence. The early universe was about three parts hydrogen to one part helium. All the heavier elements, from the oxygen in your lungs to the iron in your blood, were created through astrophysical processesβ€”fused in stars, formed in supernovae or scattered by the collisions of neutron stars. Even in the present cosmos, heavier elements are so cosmically rare that astronomers group them all as metals.

'Autonomy always begins with something a human hands it': Who's responsible when an AI agent goes rogue?

An OpenAI agent was supposed to be researching public healthcare spending, but it broke into an Australian government website instead. The June 18 hack, which saw the bot gain authorized entry into Australia's Medicare Statistics Reporting Service and access three other government systems, occurred after the AI agent encountered blocks while looking for information but "didn't accept 'no' for an answer," Australian Prime Minister Anthony Albanese said during a September 24 news conference in New York.The incident has ignited a media firestorm around OpenAI and the launch of an intensifying parliamentary inquiry. The portal contains aggregate Medicare and pharmaceutical statistics and is sepa...
