Here are 10 science news that I find interesting and important to take note.

First brain training exercise positively linked to dementia prevention identified – Aging research specialists have identified, for the first time, a form of mental exercise that can reduce the risk of dementia. Science Daily

Heavy drinking, smoking linked to visible signs of aging – Heavy drinking and smoking are linked to visible signs of physical aging, and looking older than one’s years, suggests research published online in the Journal of Epidemiology & Community Health. Science Daily

The brain’s helper cells have a hand in learning fear – Helper cells in the brain just got tagged with a new job — forming traumatic memories. When rats experience trauma, cells in the hippocampus — an area important for learning — produce signals for inflammation, helping to create a potent memory. But most of those signals aren’t coming from the nerve cells, researchers reported November 15 at the Society for Neuroscience meeting. Science News

Scientists Have Confirmed We Had Our First Ever Insterstellar Visitor Last Month – Astronomers have released the first results from an in-depth study on the suspected interstellar object that flew into our Solar System last month – and the findings are fascinating. IFLScience

Here’s What You Need to Know About That Mysterious Radiation Cloud Over Europe – After weeks of silence and denials, Russia has confirmed that it too has detected evidence of a mysterious radiation cloud floating above much of Europe, observing a dramatic radiation spike above Russia’s Ural Mountains.

Deep in The Ocean, There’s a ‘Shadow Zone’ Where The Water Is 2,000 Years Old – The oldest water in the ocean didn’t reach its advanced years by accident. Science Alert

Earth Is Getting Hit by Too Much Anti-Matter, And Nobody Knows Why – Amid the high speed cosmic rays raining down on us from the depths of space are a handful of antimatter particles called positrons. Science Alert

Simple electrocardiogram can determine whether a patient has major depression or bipolar disorder, study finds – A groundbreaking Loyola Medicine study suggests that a simple 15-minute electrocardiogram could help a physician determine whether a patient has major depression or bipolar disorder. Science Daily

How Asian nomadic herders built new Bronze Age cultures – Nomadic herders living on western Asia’s hilly grasslands made a couple of big moves east and west around 5,000 years ago. These were not typical, back-and-forth treks from one seasonal grazing spot to another. These people blazed new trails. Science News

New Study Reveals Stress Can Affect Sperm – Stress is never good for anyone, especially if it is ongoing. It affects various parts of our lives and can eventually become unhealthy. Signs of stress can include symptoms such as sweating, sleepless nights, and even nervous twitching, and can prevent us to from getting on with day-to-day tasks. IFLScience

Here are 10 science news that I find interesting and important to take note.

Potential new autism drug shows promise in mice – Scientists have performed a successful test of a possible new drug in a mouse model of an autism disorder. The candidate drug, called NitroSynapsin, largely corrected electrical, behavioral and brain abnormalities in the mice. Science Daily

Low dose, constant drip: Pharmaceutical, personal care pollution impacts aquatic life – Traditional toxicity testing underestimates the risk that pharmaceutical and personal care product pollution poses to freshwater ecosystems. Criteria that account for ecological disruption — not just organism death — are needed to protect surface waters, which are under pressure from a growing population and escalating synthetic chemical use. So reports a new study published this week in Elementa. Science Daily

Screen time might boost depression, suicide behaviors in teens – Increased time spent in front of a screen — in the form of computers, cell phones and tablets — might have contributed to an uptick in symptoms of depression and suicide-related behaviors and thoughts in American young people, especially girls, according to a new study by San Diego State University professor of psychology Jean Twenge. The findings point to the need for parents to monitor how much time their children are spending in front of media screens. Science Daily

Ancient spiral galaxy is 11 billion years old – Astronomers have spotted a spiral galaxy more ancient than any seen before. The galaxy, called A1689B11, emitted its light 11 billion years ago, just 2.6 billion years after the Big Bang. Researchers had previously reported a spiral galaxy that dates to 10.7 billion years ago. Science News

Simulating the universe using Einstein’s theory of gravity may solve cosmic puzzles – If the universe were a soup, it would be more of a chunky minestrone than a silky-smooth tomato bisque. Sprinkled with matter that clumps together due to the insatiable pull of gravity, the universe is a network of dense galaxy clusters and filaments — the hearty beans and vegetables of the cosmic stew. Meanwhile, relatively desolate pockets of the cosmos, known as voids, make up a thin, watery broth in between. Science News

“Gluten Sensitivity” May Not Actually Be Caused By Gluten – A recent study claims that people who are gluten-sensitive may not actually be as sensitive as they think they are. Instead, something else may be the culprit, and it’s not gluten. IFL Science

Favorite Planetary Cooling Plan Is Riskier Than We Knew – Faced with the immense threat of global warming, and the refusal of world leadership to act sufficiently, many people have wondered if it is possible to keep the planet habitable through deliberate cooling. Many versions of this idea, known as geoengineering, have been proposed, but a study of the most widely discussed idea has found a nasty side-effect.

People With Certain Blood Types Appear to Be More at Risk From Air Pollution – The kind of blood you have could increase or decrease your risk of having a heart attack in response to high levels of air pollution, new research suggests. A variant ABO gene – which can only be found in A, B, and AB blood types – has been linked with elevated risk of heart attack during periods of significant air pollution, whereas people with blood type O show lower risk.

Scientists Will Look For Signs of Life on This Newly Discovered Earth-Size Planet – At just 11 light-years from our Solar System, a newly discovered exoplanet is the second-closest we’ve ever found that’s temperate enough to potentially host and sustain life. Science Alert

For The First Time Ever Scientists Have Boosted Human Memory With a Brain Implant – With everyone from Elon Musk to MIT to the US Department of Defense researching brain implants, it seems only a matter of time before such devices are ready to help humans extend their natural capabilities.
