Phys.org / Satellite record shows boreal forests expanded 12% and shifted north since 1985
The boreal forest—the world's largest terrestrial biome—is warming faster than any other forest type. To understand the changing dynamics of boreal forests, Min Feng and colleagues analyzed the biome from 1985 to 2020, ...
Phys.org / Cell division spindles self-organize like active liquid crystals—a theory that holds up
When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells. The spindle is the machinery behind that process: It latches onto chromosomes (where DNA is stored) ...
Phys.org / Mira A ejects seven Earth masses, forming a heart-shaped cloud 300 light-years away
Just in time for Valentine's Day, space offers a heart-shaped greeting. The star Mira A, about 300 light-years from Earth, has released material into an expanding cloud of gas and dust resembling a heart. Both the amount ...
Medical Xpress / What telehealth changes for adult survivors of childhood cancers: More genetic testing, earlier screening options
Adult survivors of childhood cancers are at higher risk for another cancer—such as breast, colorectal, sarcomas and thyroid cancer—that is not a relapse of their original illness. Previous cancer therapies are largely ...
Medical Xpress / Can lifestyle changes reverse poor heart health?
We've all heard that making simple lifestyle changes today can help prevent heart disease down the line. But what if you already have key risk factors for heart disease, or even a diagnosis of heart disease itself? Is it ...
Medical Xpress / Unraveling the mystery of why some cancer treatments stop working
Cancer researchers working on immunotherapies have made a big discovery: SLAMF6, a molecule on the surface of immune cells that prevents T cells from effectively attacking tumors—and, in mice, they've found a way to neutralize ...
Medical Xpress / Light-based sensor detects early molecular signs of cancer in the blood
Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to spot early signs of cancer ...
Medical Xpress / 3D imaging traces vascular amyloid spread in the human brain, from surface arteries to deeper vessels
Researchers at Niigata University have used advanced three-dimensional (3D) imaging to reveal how amyloid β (Aβ) deposits spread along blood vessels in the human brain in cerebral amyloid angiopathy (CAA). By analyzing ...
Medical Xpress / Cancer cell study sheds light on cachexia's origins
New research from the University of Oklahoma, published today in Cancer Cell, describes for the first time a "triangle regulation theory" of cancer-induced cachexia and anorexia. Cachexia is a muscle-wasting and fat-loss ...
Phys.org / Extinct Hawaiian ibis with strangely small eyes suggests a shift to nocturnal life
Islands are famous for producing some of the world's strangest creatures, and now a new international study shows that the evolution of bird species on Hawaiian islands includes an ibis with unusually small eyes and limited ...
Phys.org / Unseen planet or brown dwarf may have hidden 'rare' fading star
One of the longest stellar dimming events ever observed was likely caused by the gigantic saucer-like rings of either an unseen brown dwarf or "super-Jupiter" blocking its host star's light, astronomers say. For decades, ...
Phys.org / Bio-based coating reveals harmful UV exposure by shifting color
Researchers at the Technical University of Munich (TUM) have developed a coating using proteins and bacteria that could enable the development of T-shirts that warn of excessive sun exposure or labels that reveal damage to ...
