The definition of autism may have become so broad that it risks confusion and even misdiagnosis, according to a new editorial by UCL professor Dame Uta Frith, whose pioneering research in the 1960s and '70s laid the foundations ...
Phys.org / Marine microbes point to ancient seawater source beneath Antarctica's Blood Falls
Salty water flowing through Antarctica's Blood Falls contains a distinct community of marine-specific microorganisms, providing evidence that the brine system beneath the glacier has a marine origin, according to a paper ...
Phys.org / South Korea records its highest-ever temperature of 42.5 C
South Korea registered its highest temperature since records began more than a century ago on Sunday, as authorities warned people to "immediately" stop all outdoor activities in affected areas.
Phys.org / Geological evidence questions the role of Agulhas Leakage in Atlantic Ocean circulation
For decades, scientists have asserted that the leakage of warm, salty Indian Ocean water south of South Africa into the Atlantic is a major contributor to the Atlantic Meridional Overturning Circulation (AMOC), a component ...
Phys.org / Bringing it all into focus—computational microscope captures 25.2 billion pixels per second across a wide field of view
When designing microscopes, optical engineers have long faced a trade-off between speed, field of view and resolution. But improving one of these properties typically comes at the expense of another. Now, a UC Berkeley–led ...
Medical Xpress / How multinucleated cells help the brain reorganize after localized astrocyte loss
The human brain contains various types of cells that collectively support its functions. In addition to neurons, nerve cells that communicate via electrical and chemical signals, it also relies on star-shaped cells known ...
Phys.org / New museum find shows nature can't stop inventing seahorses
At first glance, it looks exactly like a seahorse. It has the same horse-shaped head tilted down from the body, the same curled, grasping tail and, in the males, a fully enclosed pouch for brooding the young.
Phys.org / Homo antecessor skull layers resemble modern humans and Neanderthals, fragments suggest
A new study provides quantitative data on cranial vault thickness in Homo antecessor, based on the analysis of three parietal fragments recovered from the Gran Dolina site in the Sierra de Atapuerca, Burgos, Spain.
Medical Xpress / Large-scale brain scan study reveals unexpected differences in motor and visual regions linked to depression

Phys.org / How simple amber lights could make nights safer for insects
Approximately 40% of insect species worldwide are thought to be in decline and under threat of extinction. Among the key causes are habitat loss, pollution and climate change. Another threat is artificial light from sources ...
Phys.org / Rising seas are inundating US coastal wetlands, putting many on track to become open water
Along the three coasts of the contiguous United States, a silent race unfolds. Fueled by climate change, sea levels rise faster than at any time in recent geologic history. Meanwhile, coastal wetlands cling to a slim lead, ...
Phys.org / Stomach stone hypothesis sheds light on the evolution of dinosaur digestive systems
An international research team led by Assistant Professor Ryuji Takasaki of the Faculty of Biosphere-Geosphere Science at Okayama University of Science has published a paper proposing a new hypothesis on the evolutionary ...
