Study Finds Shrews Have Bizarre Undiscovered Ability

They shrink their brains, skulls for the winter and regrow them for the summer

(Newser) - Shrews have a bonkers and heretofore undiscovered ability that Gizmodo states sounds like "some cruel, recurring witch's curse" but that scientists say is most likely a survival mechanism. According to a study published Monday in Current Biology , the wild common shrew shrinks its skull—by up to 20%—...

Doctors Find Way to Halt Deadly Child Brain Disease

Gene therapy is 'curative' for ALD, says doctor

(Newser) - Without a risky bone-marrow transplant before symptoms appear, children with brain disease ALD can expect to live no longer than five years as nerve cells in the brain die off and erase one's ability to walk, talk, and think. Even a successful transplant can result in permanent disabilities, reports...

Women's Brains More Active Than Men's in 2 Key Areas

Those managing self-control and focus, as well as mood disorders

111 Dead NFL Players' Brains Were Studied; 110 Had CTE

But report based on a sample of players who might not represent all players

(Newser) - Research on 202 former football players found evidence of brain disease in nearly all of them, from athletes in the NFL, college, and even high school. It's the largest update on chronic traumatic encephalopathy, or CTE , a brain disease linked with repeated head blows. CTE was diagnosed in 177...

To Keep Your Brain 10 Years Younger, Do a Crossword

Daily puzzling is linked to better memory and reasoning

(Newser) - Use it or lose it, right? Researchers may not be ready to claim that word puzzles can help stave off age-related neurological diseases like Alzheimer's, but a major new study shows that there does appear to be a link between word puzzle play and improved cognition. Analyzing data from...

The Brains in Spain Are Small Because of Rain

45 shrunken, naturally preserved brains found in mass grave

(Newser) - "Naturally preserved brains are very rare," Fernando Serrulla tells Reuters . "There are only around 100 documented cases in the world." So imagine the forensic scientist's surprise when 45 naturally preserved brains—shrunken to 20% to 30% their original size but with ridges still visible—were...

Even Moderate Drinking Could Hurt Your Brain

Eight to 12 drinks a week tied to increased risk of hippocampal atrophy

(Newser) - A variety of studies have linked heavy drinking to brain damage and dementia, but a new one suggests moderate drinking might also hurt the brain and perhaps lead to memory loss. Contrary to studies suggesting drinking in moderation might actually be good for you, the latest in the British Medical ...

Lack of Sleep Juices Brain's Repair Mechanisms

But that's not actually a good thing

(Newser) - A new study on mice published May 24 in the Journal of Neuroscience shows that missing out on sleep may cause parts of our brains to start eating other parts. And the Telegraph reports that's not necessarily something you want to be happening. The study revolves around two types...

'Real Detective Work' Leads to Theory on Goya's Mystery Illness

The Spanish painter was profoundly ill for months but went on to live a long life

(Newser) - In 1793, when acclaimed Spanish painter Francisco Goya was 46, he was bedridden for months with a mysterious illness that brought on headaches, dizziness, hallucinations, and even vision and hearing problems. He eventually recovered and went on to live just past his 82nd birthday, but the illness took his hearing...

Fruit May Be the Key to Primates' Big Brains

Study finds link between brain size in primates and those who eat fruit

(Newser) - An apple a day can keep the doctor away, but that's nothing compared to what it can do for primates, at least according to a study published Monday in Nature Ecology & Evolution . Scientists have long hypothesized that primates evolved large brains because they needed them for complex social...

Our Brains May Be Suffering Thanks to GPS

Without exercise, hippocampus could begin to change

(Newser) - Maybe this helps explain why people drive into lakes because of their GPS. A study in Nature suggests that parts of our brain switch off when navigating with it. Indeed, as more and more people rely on GPS, the human ability to navigate as a whole could suffer, researchers at...

There's More Good News About Eating Mediterranean

The diet (perhaps not the fish) prevents brain shrinkage: study

(Newser) - A healthy diet isn't just good for your waistline, but also your brain, say scientists in a study in Neurology —the latest to tout the benefits of the Mediterranean diet . About 400 healthy Scottish volunteers kept a food diary at age 70, then underwent MRI scans of their...

Scientists Believe They've Found Fossilized Dino Brain

It would be a major first

(Newser) - Are we one step closer to Jurassic Park? Probably not, but researchers do believe they've found the first ever example of fossilized brain tissue from a dinosaur, National Geographic reports. The fossil was found on an English beach in 2004, but its unique trait—mineralized pieces of brain tissue—...

Brains of Kids as Young as 8 Altered After One Football Season

Players don't even need a full-blown concussion to suffer adverse effects: study

(Newser) - Grade-school football players may not ever experience a concussion, but just one season of "sub-concussive head impacts"—blows to the head that aren't quite severe enough to cause a full-blown concussion—could be enough to alter young athletes' brains, ABC News reports. Per a study in the...

Study Finds Long Yawns Are Sign of Big Brain

That's because yawns are actually a cooling mechanism for the brain

(Newser) - Yawning doesn't mean you're bored, it just means you've got one big, hot brain in your head, according to a study published Tuesday in Biology Letters . The Atlantic reports researcher Andrew Gallup had his students go online to collect videos of animals yawning (not a hard task...

Exercise Is Good for Your Brain, Just Don't Skip Workouts

Beneficial blood flow to the brain from exercise doesn't last

(Newser) - Think it's OK to take a week off from working out? Think again ... if you even can. A study published last month in Frontiers in Aging Neuroscience finds the benefits of exercise on the brain can fade after just 10 days. Previous studies have shown that exercise increases blood...

Study Suggests Link Between Air Pollution, Alzheimer's

Magnetite a 'plausible risk factor' for disease, says author

(Newser) - Air pollution has been linked to strokes, heart attacks , autism , and raised blood pressure . Now, scientists say it might also be responsible for Alzheimer's disease.
