For The First Time, Scientists Have Captured Video of Brains Clearing Out Dead Neurons

by DAVID NIELD We already know that our brains have a waste disposal system that keeps dead and toxic neurons from clogging up our biological pathways. Now, scientists have managed to capture a video of the process for the first time, in laboratory tests on mice. There’s still a lot we don’t know about howContinue reading “For The First Time, Scientists Have Captured Video of Brains Clearing Out Dead Neurons”

Fascinating Study Finds That Stressed Out Baby Worms Tend to Live Longer

by David Nield Scientists researching a key aspect of biochemistry in living creatures have been taking a very close look at the tiny Caenorhabditis elegans roundworm. Their latest results show that when these nematodes get put under more biochemical stress early in their lives, they somehow tend to live longer. This type of stress, calledContinue reading “Fascinating Study Finds That Stressed Out Baby Worms Tend to Live Longer”

These 6 Specific Exercises Can Cut Body Weight, Even if You’re Predisposed to Obesity

by DAVID NIELD We know that a range of factors influence weight, including those related to lifestyle and genetics, but researchers have now identified six specific exercises that seem to offer the best chance of keeping your weight down – even if your genes don’t want you to. Based on an analysis of 18,424 HanContinue reading “These 6 Specific Exercises Can Cut Body Weight, Even if You’re Predisposed to Obesity”

Gut microbes can impact the efficacy of Parkinson’s disease medications

by DAVID NIELD Dosing medicines can be a tricky process: How much of a medication actually ends up hitting its target can vary a lot between patients, sometimes for mysterious reasons. As it turns out, even the things living in our bodies could be gobbling up our drugs. In a series of experiments with levodopaContinue reading “Gut microbes can impact the efficacy of Parkinson’s disease medications”

Scientists Identify The Location of ‘Taste’ in Your Head, And It’s Not The Tongue

by David Nield How exactly do our brains sort between the five taste groups: sweet, sour, salty, bitter and umami? We’ve now got a much better idea, thanks to research that has pinned down where in the brain this taste processing happens. Step forward: the insular cortex. Already thought to be responsible for everything fromContinue reading “Scientists Identify The Location of ‘Taste’ in Your Head, And It’s Not The Tongue”

The World Just Got Closer to a Controversial Mosquito ‘Wipe Out’ Experiment

by David Nield Scientists are genetically modifying mosquitoes in a high-security lab – and they’re hoping the insects will help wipe out some of the mosquito-borne diseases that continue to plague communities worldwide. It’s known as a gene drive: where mosquitoes modified to be incapable of passing on a particular virus are used to replaceContinue reading “The World Just Got Closer to a Controversial Mosquito ‘Wipe Out’ Experiment”

The reason that sonar makes whales beach themselves

by David Nield Since the 1980s scientists have spotted a link between naval sonar systems and beaked whales seemingly killing themselves – by deliberately getting stranded on beaches. Now, researchers might have revealed the horrifying reason why. In short, the sound pulses appear to scare the whales to death, acting like a shot of adrenalineContinue reading “The reason that sonar makes whales beach themselves”

Scientists Have Detected an Entirely New Visual Phenomenon in The Human Eye

by DAVID NIELD New research suggests the human eye and brain are capable of seeing ghosted images, a new type of visual phenomenon that scientists previously thought could only be detected by a computer. It turns out our eyes are more powerful than we thought. The discovery could teach us more about the inner workingsContinue reading “Scientists Have Detected an Entirely New Visual Phenomenon in The Human Eye”

Scientists Say They’ve Found The Driver of False Beliefs, And It’s Not a Lack of Intelligence

by DAVID NIELD Why is it sometimes so hard to convince someone that the world is indeed a globe, or that climate change is actually caused by human activity, despite the overwhelming evidence? Scientists think they might have the answer, and it’s less to do with lack of understanding, and more to do with theContinue reading “Scientists Say They’ve Found The Driver of False Beliefs, And It’s Not a Lack of Intelligence”

Scientists Think They’ve Found The Part of The Brain That Makes People Pessimistic

\ by DAVID NIELD A specific part of the brain called the caudate nucleus could control pessimistic responses, according to animal tests, a finding which might help us unlock better treatments for mental disorders like anxiety and depression. These disorders often come with negative moods triggered by a pessimistic reaction, and if scientists can figureContinue reading “Scientists Think They’ve Found The Part of The Brain That Makes People Pessimistic”
