Scientists have found that microglia, a type of nervous system cell suspected to cause retinal damage, surprisingly had no damaging role during prion disease in mice. In contrast, the study findings indicated that microglia might delay disease progression. »
In the Atlantic Ocean, a giant ‘conveyor belt’ carries warm waters from the tropics into the North Atlantic, where they cool and sink and then return southwards in the deep ocean. This circulation pattern is known as the Atlantic Meridional Overturning Circulation and it’s an important player in the global climate, regulating weather patterns in the Arctic, Europe, and around the world. »
An infectious fungal disease has driven mass amphibian die-offs worldwide and is responsible for the greatest loss of biodiversity attributable to a single pathogen ever recorded. »

Research may lead to improved treatments for those with impaired hearing, improved sound interpretation by machines. »
Honey bees aren’t the only pollinators of apple flowers: bumble bees, sweat bees, mason bees and many other species do, too—and the more the better, according to findings of a study. »
Cognitive frailty is a heterogeneous clinical manifestation characterized by the simultaneous presence of both physical frailty and cognitive impairment, in the absence of dementia, and it seems to entail a greater death risk than physical frailty or cognitive impairment separately. »
Marine organisms in the Southern Ocean may find themselves between a rock and a hard place by the end of the century as ocean acidification creates a shallower zone for life. »
Researchers have found that persistently poor sleep causes the brain to clear a significant amount of neurons and synaptic connections, and recovering sleep might not be able to reverse the damage. »
Some 1.8–4.1 billion people living in the developing countries of South Asia, South-East Asia, Sub-Saharan Africa and Latin America are vulnerable to heat-related stress, and lack access to technology to cool their living spaces. »
A team of scientists used liquid metal and a liquid electrolyte to convert gaseous CO2 into a solid, coal-like substance, a breakthrough that could change the ways carbon is removed from the atmosphere and permanently stored. »
Teenagers who reach for objects, such as food or makeup, while driving increase their risk of crashing nearly seven times. »
The world's forests are increasingly taking up more carbon, partially offsetting the carbon being released by the burning of fossil fuels and by deforestation in the tropics. »
A research team led by the University of Granada is the first one in the world in describing a novel reproductive mechanism in plants, which they have called ‘anther rubbing’. »
Scientists from the University of Bristol and UC Davis say zebras may have gotten their stripes to confuse ectoparasites, such as flies. »
There is not enough evidence related to the effects of noncaloric sweeteners on appetite, short‑term intake, and risk of suffering from cancer or diabetes. »
Rising temperatures will cause at least a third of the ice in the Himalayas to vanish by the end of the century, endangering the lives and livelihoods of nearly two billion people who are dependent on glacier-fed rivers for their water resources. »
Researchers have proposed a design solution that could improve leaf, which would use carbon dioxide from the air, and convert CO2 to fuel at least 10 times more efficient than natural leaves. »
Researchers have shown that a type of magnetic resonance imaging — called neuromelanin-sensitive MRI (NM-MRI) — is a potential biomarker for psychosis. »
When the great white shark disappeared from a specific area off the coast of South Africa, a Jurassic-era predator called the sevengill shark moved in. »
The filling and draining of meltwater lakes has been found to cause a floating Antarctic ice shelf to flex, potentially threatening its stability. »
A dinosaur that wore its "heart" on its tail is providing new clues to how ecosystems evolved on the African continent during the Cretaceous Period some 100 million years ago, according to researchers at Ohio University. »
Most people will at some point in their life experience one of many the downsides of excess drinking: the hangover. Importantly, hangovers can lead to reduced productivity, impaired performance and even risk to daily tasks such driving or operating heavy machinery. »
Male butterflies have genes which give them a sexual preference for a partner with a similar appearance to themselves, according to new research. »
The newly-created and most accurate 3D map of galaxy reveals that it’s warped and twisted, and even more fascinating. »
Researchers have found that treating psoriasis, a chronic inflammatory skin disease, with biologic drugs that target immune system activity can reduce the early plaque buildup that clogs arteries, restricts blood flow, and leads to heart attacks and stroke. »
A gigantic cavity - two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall - growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier. »

A novel technology was developed by Indian-origin researchers that can clean water twice as fast as commercially available ultrafiltration membranes. »
In the largest study of its kind to date, Cambridge researchers have looked at why some people manage to stay thin while others gain weight easily. They have found that the genetic dice are loaded in favour of thin people and against those at the obese end of the spectrum. »
A new study in rodents has shown that the brain’s cerebellum—known to play a role in motor coordination—also helps control the brain’s reward circuitry. »
Greenland's ice is melting faster than previously thought, according to a new study. »
Using a novel patient-specific stem cell-based therapy, researchers at the National Eye Institute prevented blindness in animal models of geographic atrophy, the advanced "dry" form of age-related macular degeneration. »

Planetary scientist Vlada Stamenković of the NASA Jet Propulsion Laboratory and colleagues have developed a new chemical model of how oxygen dissolves in Martian conditions, which raises the possibility of oxygen-rich brines; enough, the work suggests, to support simple animals such as sponges. »
As much of the ocean responds to the rising temperatures of today’s world, the deep, dark waters at the bottom of the Pacific Ocean appear to be doing the exact opposite. »
