Phys.org / Webb reveals warped structure in nearby TW Hydrae's protoplanetary disk
Using the James Webb Space Telescope (JWST), astronomers obtained high-contrast coronagraphic images of the protoplanetary disk around the young, nearby star TW Hydrae. Results of the observational campaign, published July ...
Phys.org / This summer isn't breaking heat records—yet. Wait until El Nino kicks in, scientists say
Wildfires are burning in North America and Europe. Deadly heat waves have parked over cities and the world's oceans are the hottest ever recorded for this time of year. A strengthening El Niño is forecast to be off-the-charts, ...
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 ...
Medical Xpress / Like Zika, Oropouche virus can also affect the brains of unborn babies
Discovered in 1955, the Oropouche virus has circulated mainly in the Amazon, causing a febrile illness virtually indistinguishable from those caused by dengue, Zika and chikungunya, viruses also transmitted by biting mosquitoes.
Medical Xpress / Evolutionary history may help explain why some people develop more severe COVID-19 than others
Every time a virus invades a person, it collides with thousands of years of human history. A study led by researchers at the USC Dornsife College of Letters, Arts and Sciences and Howard University suggests that some of the ...
Phys.org / In Atlantic Forest restoration, connection between fragments is more important than fragment size
Seed dispersal through wind, water or animals is a crucial process for forest renewal and biodiversity preservation. In the Atlantic Forest, a new study showed that the amount of forest in the landscape surrounding an area ...
Medical Xpress / Turning a common oncogene's metabolic grip on cancer cells into a fatal weakness
For all its persistence as an adversary, aggressive breast cancer carries a weakness of its own making. A University of Helsinki research group has been investigating where this weakness comes from and how it can be exploited. ...
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 / Scientists build 'cell villages' to map the genetics of brain cell fitness
How readily a cell divides and how well it survives are fundamental to life, shaping everything from organ size to the body's ability to withstand disease. That combination, known as cell fitness, isn't the same for everyone. ...
Phys.org / Unexpected bond-breaking order reveals a new path to bioluminescence
The dancing lights of fireflies and the eerie blue sparkle in crashing waves get their glow when a molecular square of carbon and oxygen atoms breaks. New research from Stanford University has shown that mechanical force ...
Medical Xpress / Has the definition of autism become too broad to be useful?
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 / 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.
