    Arsenic contamination in rice poses a serious health risk in many parts of the world. But an international study has shown that husking rice before parboiling reduces arsenic content, potentially lowering the risk of cancer. »
    An international team of scientists has found part of the world’s largest ice shelf is melting 10 times faster than the overall ice shelf average due to solar heating of the surrounding ocean surface. »

    A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope. »
    Stalagmites in a remote cave in northeast India hold climate secrets that can help predict rainfall patterns, floods and droughts in the sub-continent. »
    Researchers have found that certain organic semiconducting materials can transport spin faster than they conduct charge, a phenomenon which could eventually power faster, more energy-efficient computers. »
    What looks like a red butterfly in space is in reality a nursery for hundreds of baby stars. »
    A new research says that the dietary cholesterol in eggs is associated with a heightened risk of cardiovascular disease and early death — even though plenty of nutrition experts, consider eggs part of a healthy diet. »
    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. »
    Scientists see four-fold increase in ocean’s annual carbon uptake. »
    Eating a calcium-rich diet or taking calcium supplements does not appear to increase the risk of age-related macular degeneration (AMD), according to the findings of a study. »
    Researchers at NASA's Jet Propulsion Laboratory in Pasadena, California, are cooking up an alien atmosphere right here on Earth. »
    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. »
