Blue Light from LEDs Can Rot the Brains of Fruit Flies, Study Finds

The blue light that emanates from every smartphone and fluorescent bulb isn’t thought to be great for our health, particularly the health of our eyes. But a new study in fruit flies suggests that blue light can even be harmful to brains and speed up aging – again, in fruit flies. There’s a very long way to go before we could assume the same is true for people. Read More >>

Toxic Algae Blooms Really Have Become More Intense, Study Finds

A new study out Monday seems to confirm an unpleasant reality: Potentially toxic algae blooms in the world’s freshwater lakes have become more intense over the last 30 years. And while climate change may not be the only reason why blooms have gotten worse, rising temperatures are likely making it harder for lakes to recover from them. Read More >>

A Study That Linked Shorter Lifespans to CRISPR Baby Mutation Has Been Retracted

An alarming study that added fuel to the fire over a recent controversial genetic experiment in China has now been invalidated. The study, which suggested that a mutation induced by Chinese scientist He Jiankui in human babies could shorten their lives, was retracted late last week, after other scientists failed to find similar results and the study’s authors admitted to a flaw in its design.

Viagra Might Someday Enhance Bone Marrow Transplants

The long story of sildenafil citrate, best known by the brand name Viagra, may have another chapter to it. Researchers at the University of California Santa Cruz think the drug can improve how we perform bone marrow transplants, as part of a combination therapy that allows doctors to harvest stem cells from patients quicker and safer than the traditional method. So far, though, it’s only been tested in mice. Read More >>

Over 33,000 Brits Have Rare DNA Fluke and Don’t Know It, Study of 23andMe Data Finds

A supposedly rare genetic quirk might be more common than we think, according to new research out Thursday. The study, based largely on 23andMe data, suggests that one in every 2,000 people are born with two copies of a gene from only a single parent, often with no serious health consequences.

Scientists Invent LED Device to Quickly Treat Carbon Monoxide Poisoning, Though It’s Not Ready for Humans Yet

Doctors at Harvard think they’ve found a new way to stop a silent killer by literally shining a light on it. In experiments with rats, their light-based device was able to quickly clear away carbon monoxide stuck to blood cells. The nifty invention may someday help doctors and EMTs treat life-threatening cases of carbon monoxide poisoning in humans. Read More >>

E-Cigarette Vapour Linked to Lung Cancer in Mice

A new study out Monday is yet more evidence that vaping isn’t the safe alternative to smoking it was once thought to be. The researchers claims to have found evidence, in mice, that e-cigarette vapour is capable of causing certain kinds of cancer. But of course, there’s still a long way to go before we can know if the same is true in people and how large of a cancer risk it could pose. Read More >>

2019 Nobel Prize in Medicine Goes to Researchers Who Unravelled How Cells Sense Oxygen

A trio of researchers from the US and the UK has won the 2019 Nobel Prize in Medicine, the first of five prizes to be announced this week. Today in Sweden, the Nobel committee announced that Americans William Kaelin Jr. and Gregg Semenza, along with Peter Ratcliffe, would split the nearly million-dollar prize for their work in unravelling a fundamental aspect of life: how our cells keep track of and respond to fluctuating oxygen levels.

Prospective Fathers Should Avoid Binge Drinking, Study Finds

Prospective parents – but especially dads – might be wise to avoid too much alcohol, according to a new study out this week. It suggests that women and men who binge drink in the months before conception are more likely to have children with congenital heart defects, with the father’s alcohol consumption surprisingly having a greater impact on the future child’s heart health.

A 1964 Earthquake Might Have Unleashed a Deadly Fungus on the Pacific Northwest

Two decades ago, a rare but deadly fungal infection began killing animals and people in the US and Canada. To this day, no one has figured out how it arrived there in the first place. Now a pair of scientists have put forth their own theory: Tsunamis, sparked by a massive earthquake in 1964, soaked the forests of the Pacific Northwest with water containing the fungus.

Human Foetuses Develop Lizard-Like Body Parts That Disappear Before Birth

New research this week seems to show that human foetuses develop several muscles in their legs and arms that disappear by the time they’re born. And some of these muscles were last seen in our adult ancestors over 250 million years ago. Read More >>

A Brain-Infecting Virus Carried by Mosquitoes Is Spreading Far and Wide Across the US This Year

Last weekend, health officials in several US states reported more cases and deaths linked to the Eastern Equine Encephalitis (EEE) virus. The number of cases, while still small, is set to make 2019 the worst recorded year for EEE in recent history – and it may be a sign of things to come in an ever-warming climate. Read More >>
