Now, after the lab team’s decade of close collaboration with scientists at Google, that data has turned into the most detailed map of a human brain sample ever created. The result is an interactive 3D model of the brain tissue, and the largest dataset ever made at this resolution of a human brain structure. And of course, it would reveal many more problems, things we hadn’t expected.”What about mapping an entire human brain? “Much of what we think we understand about the human brain is extrapolated from animals, but research like this is critical for revealing what truly makes us human. “Each human brain is a vast network of billions of nerve cells,” said Sporns, distinguished professor of psychological and brain sciences at Indiana University.

☆ Video gamers may be risking hearing loss or tinnitus, study finds
▼ + stars: | 2024-01-16 | by ( Kristen Rogers | ) edition.cnn.com time to read: +7 min

“One study showed that individuals who play video games for longer times are at higher risk of developing hearing loss or tinnitus.”Tinnitus refers to an internal sensation of a ringing, buzzing or roaring sound in one or both ears. That’s why the study’s authors wondered what the relationship with hearing loss and tinnitus might be — especially since many games also have loud sudden sounds such as gunshots or engines revving. “This can result in temporary hearing loss or ringing in the ears,” she added. But hearing damage is permanent, and exposure to high-intensity sounds when young could make kids more vulnerable to developing age-related hearing loss later, so the authors have urged the importance of prevention. “Key warning signs of hearing loss include experiencing tinnitus, difficulties hearing high-pitched sounds or difficulties following conversations,” Dillard said.

Yet even if you’re a rock star at snoring, you may not know you have obstructive sleep apnea unless someone tells you about your nocturnal roars. Here are five weird signs of obstructive sleep apnea to watch for, according to Dasgupta. But research has shown that about 30% of people with obstructive sleep apnea have reported night sweats, Dasgupta said. Teeth grindingGrinding or clenching teeth while sleeping is called bruxism, and it too may be a sign of obstructive sleep apnea, Dasgupta said. “Women especially have a tendency to underreport atypical symptoms such as insomnia, fatigue and depression.”If obstructive sleep apnea awakens you, it may be hard to go back to sleep.

The find is also the oldest fully aquatic whale found in Africa, according to a new study. Tutcetus rayanensis is a member of the extinct family of early whales known as basilosauridae — the first widespread group to become fully aquatic. The discovery of the whale fossil led to the establishment of a new genus within the basilosauridae family. The area is one of the world’s “most productive fossil whale sites,” according to the study. Tutcetus rayanensis is the second whale species, following Phiomicetus anubis, to be discovered, described, and named by Egyptian paleontologists,” Antar said via email.

☆ Is cortisol sabotaging your weight loss efforts? Experts sound off

CNN —You might believe cortisol is the culprit sabotaging your fitness and weight loss efforts if you’re getting your guidance from social media. And if you could just get your cortisol levels to where they need to be, everything else will fall into place — right? There are lab tests to determine if cortisol levels are where they should be, but they are usually only given to people who have a condition affecting cortisol levels, Vincent said. But some daily activities can also affect our cortisol levels. And if someone is looking to incorporate more exercise, the best workouts are the ones that keep them going, Hodges said.

☆ Red light therapy: How it affects sleep

CNN —Red light therapy has been found to be helpful for skin health, wound healing, hair growth among people with alopecia and pain management. “That’s why when we talk about blue light or red light, we’re not talking about a red-colored light bulb. A 2019 study led by Figueiro looked into whether delivering red light to closed eyes during sleep — using a red light mask — and to open eyes upon waking — via red light goggles — reduced sleep inertia among 30 adults. In other words, it might be that any benefits come from replacing the light you’re exposed to before sleep with red light, rather than adding the latter during sleep. The bottom line is that when it comes to sleep, “what’s better than red light is no light,” Dasgupta said.

“Laziness is like, ‘I have absolutely no desire to even think about this.’ Procrastination is, ‘It troubles me to think about this. “It can leave people feeling very defeated and feeling like there’s no point in trying.”Knowing why you procrastinate can make you self-aware, but you still need strategies to break the habit. The types of procrastinationA procrastinator is usually a perfectionist, Yip said. “Because the perfectionist needs things done perfectly — all Ts crossed and Is dotted — it takes an insurmountable amount of effort. “Defiers usually don’t feel equipped to have these conversations with who they see as authority figures, or they don’t believe that having the conversations would give them any benefit or positive outcome.

Develop a sleep debt from those worries, and you’ll pay a price in your ability to think, plan and manage your emotions. “Sleep debt, also called a sleep deficit, is the difference between the amount of sleep someone needs and the amount they actually get,” said sleep specialist Dr. Raj Dasgupta, an associate professor of clinical medicine at the University of Southern California’s Keck School of Medicine. Research has found many people have little idea how much poor sleep has affected their mood and coping skills, said Dr. Bhanu Prakash Kolla, a sleep medicine specialist in the Center for Sleep Medicine at the Mayo Clinic in Rochester, Minnesota. Loss of sleep can directly affect your ability to control emotions and manage expectations, said Dr. Bhanu Prakash Kolla of the Mayo Clinic. “Sleep medications are seldom the solution for chronically poor sleep and impaired daytime functioning,” he said.

☆ Rare success for Alzheimer's research unlocks hope for future therapies

Eisai and Biogen are scheduled to present full data from their lecanemab study on Tuesday at the Clinical Trials on Alzheimer's Disease conference in San Francisco. Lecanemab’s success rests on years of research into the causes of Alzheimer’s as well as advances in measuring amyloid deposits through brain scans and spinal fluids. At least 16 treatments are being tested in clinical trials, with results expected over the next three years, according to a Reuters review of the clinicaltrials.gov registry. The drugmaker has been largely absent from the Alzheimer's space after the high-profile failure of its drug verubecestat five years ago. But several antibody therapies from Lilly, Biogen and AbbVie(ABBV.N) that were designed to slow the rate of tau accumulations failed outright last year.

The US Department of Agriculture recommends planning for one pound of turkey meat per person when preparing a holiday meal. “Tryptophan from turkey is unlikely to enter the brain and make enough serotonin to make us sleepy,” Malin said. “Turkey doesn’t really make us sleepy,” Knutson said. “Remember all the delicious side dishes surrounding the center piece of turkey, such as sweet potato pie, casseroles and yummy desserts,” he said. “Alcohol slows down your brain and relaxes your muscles so after a few drinks you’ll likely feel sleepy.”

Why we feel sleepy after a big Thanksgiving mealSerotonin is one of the “feel-good” hormones, which can calm and relax the body. The US Department of Agriculture recommends planning for 1 pound of turkey meat per person when preparing a holiday meal. “Tryptophan from turkey is unlikely to enter the brain and make enough serotonin to make us sleepy,” Malin said. “These tasty dishes contain a high amount of carbohydrates, which also contribute to post-meal sleepiness.”Another reason you feel sleepy after a meal is a change in blood flow from the head to the digestive system. “Alcohol slows down your brain and relaxes your muscles, so after a few drinks you’ll likely feel sleepy.”

The analysis also found over 30% of adults reported an hour of sleep debt -— when you sleep less than your body needs — while nearly 1 in 10 adults had a sleep debt of two hours or more. “This is a well done study examining a very large and representative sample,” said Dr. Bhanu Prakash Kolla, a sleep medicine specialist in the Center for Sleep Medicine at the Mayo Clinic in Rochester, Minnesota. Social jet lagIn addition, nearly half of the adults in the study reported social jet lag – a bad fit between the sleep timing preferred by a person’s inner biological clock and the one dictated by society. Over 46% of the survey participants reported at least 1 hour of social jet lag, while 19.3% experienced at least 2 hours. Untreated social jet lag can have serious consequences, including insomnia, early waking or excessive sleepiness, daytime fatigue, difficulty concentrating, constipation or diarrhea and increased cortisol levels.

☆ Fact Check-Video of doctor saying world is flat on CBS is missing context

A video of a doctor saying “the world is flat” has been taken out of context on social media. The book does not claim that the Earth is flat; Friedman uses the term “the world is flat” as a metaphor to talk about the impacts of globalization. The video clip posted on Instagram with text that says, “Doctor on CBS News Mentions Flat Earth Twice Out Of Nowhere,” was liked over 1,500 times at the time of writing (here). In a 2016 CBS interview, David Agus is not claiming that the Earth is flat. He is using the term “the world is flat” as a reference to describe how globalization makes viruses spread more quickly.
