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

What training exercise boosts brain power best? New research finds out – One of the two brain-training methods most scientists use in research is significantly better in improving memory and attention, Johns Hopkins University researchers found. It also results in more significant changes in brain activity. Science Daily

Brain waves reflect different types of learning – Figuring out how to pedal a bike and memorizing the rules of chess require two different types of learning, and now for the first time, researchers have been able to distinguish each type of learning by the brain-wave patterns it produces.

A universal flu shot may be nearing reality – One of the planet’s deadliest viruses makes an annual pass through the United States with little fanfare. It rarely generates flashy headlines or news footage of health workers in hazmat suits. There’s no sudden panic when a sick person shows up coughing and feverish in an emergency room. Yet before next spring, this season’s lethal germ will probably have infected millions of Americans, killing tens of thousands. Still, it’s often referred to as just the flu. Science News

Your eyes make waste. Without it, you could go blind – One man’s trash is another man’s treasure, even at the level of the cell. That’s where—according to new research—a waste product of the retina fuels part of the eye that powers the rods and cones that help us sense light. Without this waste, that part of the eye “steals” glucose from the retina, leading to the death of retinal cells and likely vision loss. The finding could help explain why eyesight degenerates with age—and in diseases such as macular degeneration and diabetes. Science

Was this ancient person from China the offspring of modern humans and Neandertals? – When scientists excavated a 40,000-year-old skeleton in China in 2003, they thought they had discovered the offspring of a Neandertal and a modern human. But ancient DNA now reveals that the “Tianyuan Man” has only traces of Neandertal DNA and none detectable from another type of extinct human known as a Denisovan. Instead, he was a full-fledged member of our species, Homo sapiens, and a distant relative of people who today live in East Asia and South America. The work could help scientists retrace some of the earliest steps of human migration. Science

Blood Transfusions From Some Women Can Be More Dangerous For Men, Says Study – Providing a detailed medical history when donating blood could be more important than we know – and not just when it comes to screening for disease. Science Alert

An Alzheimer’s Drug Has Been Found to Help Teeth Repair Themselves in Just 6 Weeks – Dental fillings may soon be left in the ash heap of history, thanks to a recent discovery about a drug called Tideglusib. Developed for and trialled to treat Alzheimer’s disease, the drug also happens to promote the natural tooth regrowth mechanism in mice, allowing the tooth to repair cavities. Science Alert

In many places around the world, obesity in kids is on the rise – Over the last 40 years, the number of kids and teens with obesity has skyrocketed worldwide. In 1975, an estimated 5 million girls and 6 million boys were obese. By 2016, those numbers had risen to an estimated 50 million girls and 74 million boys, according to a report published online October 10 in the Lancet. While the increase in childhood obesity has slowed or leveled off in many high-income countries, it continues to grow in other parts of the world, especially in Asia. Science News

Having A High IQ Puts You More At Risk Of Mental Illness, Study Finds – If you look at television shows featuring a genius you very quickly see a pattern emerge. Hugh Laurie’s TV-doctor, House, is a medical genius but struggles with severe depression as well as a messiah complex. Sherlock Holmes can solve any case, but has many addictions and may just be a sociopath. Countless TV shows, films, and books all peddle the idea that highly intelligent people are prone to mental illness. IFLScience

Nine Year Study Finally Explains The Relationship Between Sugar And Cancer – Scientists have discovered the exact relationship between sugar and cancer by revealing that the way in which cancer cells break down sugar is linked to the stimulation of tumor growth. Cancer cells tend to produce energy differently from normal cells – they use a process that involves fermentation of glucose into lactate, rather than ordinary respiration. IFLScience
