Wednesday Science News Roundup #25

Below are 10 science news that I found interesting and are related to topics I care about.

New CRISPR method efficiently corrects Duchenne muscular dystrophy defect in heart tissue – Scientists have developed a CRISPR gene-editing technique that can potentially correct a majority of the 3,000 mutations that cause Duchenne muscular dystrophy (DMD) by making a single cut at strategic points along the patient’s DNA, according to a new study. Science Daily

Magnetic brain stimulation alters negative emotion perception – A new study reports that processing of negative emotion can be strengthened or weakened by tuning the excitability of the right frontal part of the brain. Science Daily

Brain pacemaker study shows promise in slowing decline of Alzheimer’s – Researchers have studied how using an implant — likened to a pacemaker for the brain — could help Alzheimer’s patients to retain cognitive, behavioral and functional abilities longer while also improving quality of life. Science Daily

It’s a bad idea for a toad to swallow a bombardier beetle – Toad versus bombardier beetle is almost a fair fight. Toads are hugely bigger, can tongue-strike in an eyeblink and swallow all kinds of nasty stuff. But bombardier beetles can shoot hot steam and noxious chemicals from their back ends. Science News

A blood test could predict the risk of Alzheimer’s disease – A new blood test might reveal whether someone is at risk of getting Alzheimer’s disease. Science News

Insane Numbers of Viruses Are Constantly Falling on Us From The Sky, Study Shows – If there are viruses on the ground and viruses in the water, one might expect there are viruses in the sky as well. Science Alert

Ingredient In McDonalds Fries Key To Curing Baldness, Researchers Find – You wouldn’t expect a McDonald’s Happy Meal to be a cure for anything, unless you’re chronically underweight. However, a new study has found that a key ingredient in making the meals might be better used to cure baldness. IFLScience

Woodpeckers Seemingly Avoid Brain Damage Despite The Build Up Of Abnormal Tau Proteins – As an animal that spends much of its time hammering its head against trees at a force of 1,200 g’s, it’s unsurprising that many sports companies have looked to the woodpecker’s biology to design better safety equipment and helmets for football players, in order to protect them against brain damage. IFLScience

New Data Shows TRAPPIST-1 Planets Are More Habitable Than We Ever Thought – You’ve probably been on the edge of your seat wondering what the TRAPPIST-1 planetary system has been up to. Now we have four new studies that have probed the planets and its star, and found that they definitely bear further investigation in our search for extraterrestrial life. Science Alert

For The First Time Ever, Astronomers Have Detected Planets Outside Our Galaxy – In an incredible world first, astrophysicists have detected multiple planets in another galaxy, ranging from masses as small as the Moon to ones as great as Jupiter. Science Alert

Wednesday Science News Roundup #21

Below are 10 science news that I found interesting and are related to topics I care about.

Alzheimer’s drug turns back clock in powerhouse of cell – The experimental drug J147 is something of a modern elixir of life; it’s been shown to treat Alzheimer’s disease and reverse aging in mice and is almost ready for clinical trials in humans. Now, Salk scientists have solved the puzzle of what, exactly, J147 does. In a paper published January 7, 2018, in the journal Aging Cell, they report that the drug binds to a protein found in mitochondria, the energy-generating powerhouses of cells. In turn, they showed, it makes aging cells, mice and flies appear more youthful. Science Daily

At least 3 out of 5 people who try a cigarette become daily smokers – At least 61 per cent of people who try their first cigarette become, at least temporarily, daily smokers, suggests an analysis of survey data by Queen Mary University of London. Science Daily

This Common Painkiller Could Be Negatively Affecting Male Fertility – Male fertility could be at a tipping point. Last year, scientists discovered sperm counts in western countries had plummeted by 50 percent in 40 years, and while the reasons behind the decline are complex, many researchers say the phenomenon is due to men’s hormones being disrupted. Science Alert

Britain Now Generates Twice as Much Electricity From Wind as Coal, And That’s a Big Deal – Just six years ago, more than 40 percent of Britain’s electricity was generated by burning coal. Today, that figure is just 7 percent. Science Alert

These Birds of Prey Are Deliberately Setting Forests on Fire – It’s pretty hot in Australia right now. A brutal heatwave that’s incinerated temperature records threatens devastating bushfires – and to make matters worse, authorities have to contend with an ancient breed of flying arsonists that may as well be miniature dragons. Science Alert

Magic Mushrooms Could Treat Depression Without The Emotional Numbing Caused By Traditional Antidepressants – Magic mushrooms could hold the key to alleviating symptoms of depression, particularly in those who have not benefited from more traditional treatments, new research finds. IFLScience

Pharmaceutical Giant Pfizer Pulls Plug On Alzheimer’s And Parkinson’s Drug Research – Pfizer, one of the world’s biggest pharmaceutical giants, is going to ditch their research efforts into new drugs to fight against Alzheimer’s disease and Parkinson’s disease. IFLScience

Protein Linked To Alzheimer’s Seen Spreading Like An Infection – For the first time, researchers have observed tau proteins, one of the presumed causes of Alzheimer’s disease, spreading from neuron to neuron in a manner similar to how an infection might advance in tissue. IFLScience

White dwarf’s inner makeup is mapped for the first time – Astronomers have probed the inner life of a dead star. Tiny changes in a white dwarf’s brightness reveal that the stellar corpse has more oxygen in its core than expected, researchers report online January 8 in Nature. The finding could challenge theories of how stars live and die, and may have implications for measuring the expansion of the universe. Science News

CRISPR gene editor could spark immune reaction in people – Immune reactions against proteins commonly used as molecular scissors might make CRISPR/Cas9 gene editing ineffective in people, a new study suggests. Science News
