Phys.org / The cost of memory: How organisms balance thinking and sensing
Remembering the past can help living organisms make better decisions, but memory comes at a cost. Whether it is an animal searching for food or a single cell responding to its surroundings, storing and using information requires ...
Phys.org / First electrically pumped perovskite polariton laser diode solves a decades-long challenge
Resolving a long-standing problem in semiconductor physics and optoelectronics, a team of researchers from Skoltech—a VEB.RF group institution—and their colleagues from ITMO University and HSE University have for the first ...
Medical Xpress / Early surgery for bacterial eye infection offers hope to patients
Early vitrectomy surgery for acute endophthalmitis, a rare eye condition, may potentially benefit patients' vision more than the current antibiotic-first approach, according to a study led by researchers at University College ...
Medical Xpress / Brain fluid structure may flag future dementia risk years before diagnosis
Dementia, a progressive loss of memory and decline in mental function that can be caused by various neurological conditions, is estimated to affect more than 57 million people worldwide. Identifying specific biological and ...
Phys.org / One LED produces four stable colors at room temperature
Full-color displays normally require separate red, green and blue light emitters. A team from the University of Osaka and Ritsumeikan University has demonstrated another approach: a single light-emitting layer that produces ...
Tech Xplore / Why making lighter and better batteries takes time
Lithium-ion batteries have revolutionized our lives since they first came onto the market in the early 1990s. They are now used in all sorts of devices, such as cellphones, laptops and electric vehicles.
Medical Xpress / Gut microbe's protective coating links intestinal colonization to lower inflammation
The human gut harbors more than 40 trillion bacteria assembled into complex communities collectively known as the gut microbiota, which is closely linked to human health and disease. Mediterraneibacter gnavus (formerly Ruminococcus ...
Phys.org / Antarctic storms are becoming more frequent and intense, affecting sea ice
Winters in Antarctica's Ross Sea have become stormier in recent decades, affecting sea-ice conditions and field operations, new University of Otago—Ōtākou Whakaihu Waka research shows.
Medical Xpress / Scientists decipher how T cells sense enemies—such as cancer—at point of contact
Every encounter between a T cell and a potential target—especially when that target is a developing tumor—begins with a rapid series of molecular decisions. Within seconds, the immune cell must determine whether to launch ...
Medical Xpress / Gut bacteria leave intestinal 'memory,' protecting against inflammation
New Northwestern Medicine research published in Nature Communications suggests that a metabolite produced by gut bacteria when they digest dietary fiber can leave a lasting molecular imprint on intestinal cells, promoting ...
Phys.org / Meet WOMBATlite, the model helping researchers follow the ocean's carbon
The ocean absorbs roughly a quarter of humanity's carbon dioxide emissions each year. Understanding how that happens, and how it might change, is essential for predicting our climate's future. To do that, scientists need ...
Phys.org / Study investigates how seven different Central European tree species respond to metal-contaminated soils
For centuries, artisanal and industrial activities have left many soils polluted with excessive levels of heavy metals such as zinc, cadmium, copper and lead, posing a threat to the environment and human health. Cleaning ...
