Children throwing tantrums should be given time to calm down on their own rather than distracted with tablets or smartphones, say researchers

What’s good for your body is good for your brain. That means eating a balanced diet with lots of fruits and veggies and not much sugar, saturated fat or alcohol, as well as getting enough exercise and sleeping about eight hours a night. But evidence is accumulating that a whole host of other activities can help keep our brains young even as we advance in chronological age. There is no one magic activity that you need to take on, but trying a handful of the following will help.

As your dog reaches old age, you might expect to contend with veterinary complaints like hip dysplasia or even cancer. But here’s one you aren’t as likely to expect: Alzheimer’s disease.
According to veterinarian Lee Harris, the condition is surprisingly common. At his veterinary practice in Southern California, he’s seen an increase in chronic conditions such as obesity, arthritis and dementia.
“Really, our brains are not that different from dogs’,” Harris wrote in The Washington Post. “The cellular changes of canine cognitive dysfunction would be recognizable under the microscope to any human brain pathologist: Plaques of beta amyloid — protein fragments believed to be the result of ‘oxidative stress’ — lead to distinctive ‘neurofibrillary tangles’ within the damaged nerve cells, and shrinkage of the brain appears in areas where memories are made and behaviors are shaped.”
The technical term for the condition, Cognitive Dysfunction Syndrome, has only more recently become recognized as a disease in dogs. Now, it is estimated that more than 50 percent of dogs over the age of 10 will exhibit symptoms of cognitive decline.
Of course, the symptoms will present themselves somewhat differently than they do in humans. Dementia may cause trained dog —> Read More Here
Have scientists discovered a new species of primitive human?
Two teams of researchers have been asking that very question after analyzing mysterious fossils found in China and Taiwan. The fossils don’t seem to fit with any known hominin species–including modern humans, Homo erectus or Neanderthals. Instead, they may be the result of interbreeding between known species, or perhaps even belong to an unknown human species.
“Classically, everything that inhabited Asia before the arrival of modern humans have been classified into a single taxon: H. erectus,” Dr. María Martinón-Torres, a dental anthropologist at Spain’s National Research Center on Human Evolution (CENIEH) and a researcher involved in one of the studies, told The Huffington Post in an email. “However, we now see that we may have put in the same box things that are different… It may be time to revise that.”

For the research, Martinón-Torres and her colleagues analyzed nine teeth from four individuals, which were unearthed in a cave at Northern China’s Xujiayao site in 1976. The teeth, which date back 60,000 to 120,000 years, were compared to more than 5,000 dental samples taken —> Read More Here

Scientists saying ‘ow’ and being vocal does help us tolerate pain.

First responders are often not able to pinpoint the location of victims when emergency calls are made from wireless devices due to defects in the US GPS satellite system, US Senator Chuck Schumer, said in a press release.
“First responders too-often can’t locate victims when 911 calls are made from cell phones,” Schumer said on Wednesday. “It is inconceivable that GPS flaws could mean the —> Read More Here
