    BOSTON, Mass. (CBS Local) – With many states dealing with record-high temperatures and massive heat waves, many people are probably sick of summer already. A new study says that your brain may hate the heat more than you do. Researchers at Harvard University have discovered that a person’s brain works 13 percent slower when it has to operate in extreme heat. According to their report in PLOS Medicine, scientists studied 44 college students living in Boston during a 2016 heat wave. That July heat wave was reportedly one of the hottest in the city’s history. 22 of the students lived...

    Canadians will soon be able to order marijuana through the mail as part of the nation’s new legalization of recreational pot. Lawmakers in the country passed the Cannabis Act earlier this week, setting the country up to regulate the market in the coming months. Prime Minister Justin Trudeau announced Wednesday that legalization will begin on Oct. 17. The country is the second to legalize the substance nationwide, after Uruguay. The federal minimum age for marijuana use in Canada will be 18, but some provinces are setting their own minimum age at 19, which is the drinking age in most areas....
  • Scientists Bring A Severed Brain Back To Life, Sparking Ethical Debate

    <p>NEW HAVEN, CT (CBS Local) – Has science gone too far? That’s the question some experts are asking after Yale University researchers announced that they have successfully reanimated a pig’s brain, which had been severed from its body.</p> <p>Yale neuroscientist Nenad Sestan revealed the breakthrough during a meeting at the National Institutes of Health (NIH) on March 28. Sestan’s team reportedly experimented on over 100 pig brains obtained from a slaughterhouse and restored their circulation using a system of pumps, heaters, and artificial blood. The researchers said they managed to reactivate the brains for up to 36 hours.</p>

    Last year, my husband and I purchased our first house. Lucky for us new homeowners, the house needed minimal work. [snip] Last month, in the middle of the night, I woke up startled. It felt like someone had placed a chip of ice in my left earhole—but it was something way worse. I shot up out of bed, disoriented, and stumbled to the bathroom. I could feel that my ear was not right. I grabbed a cotton swab and gently inserted it into my ear to see what was up and I felt something move. When I pulled the cotton...

    One of the things I fuss about a lot (especially at Buffer) are words—very simple words, in fact. Should it say “Hi” or “Hey?” Should it be “cheers” or “thanks?” How about “but” or “and?” There are many occasions when Joel and I sit over one line and change it multiple times, until we feel it really sits right. This is partly to improve our metrics for click rate and others. It is also to simply create the right emotion. The one key question we ask ourselves is: “How does this make you feel?” The question might sound very...

    SCIENTISTS have controversially yet successfully grown part of a human brain inside a mouse and the organ even managed to survive for months in a major scientific breakthrough. ____________________________________________________________________________________________________________ For the first ever time miniature human brains have grown in a new species and scientists have suggested the breakthrough could help with stem cell research. Scientists created the pin-sized human brains from stem cells and then placed them inside the skulls of mice, where a piece of tissue had been removed to make room for the new organ. Of the test mice, roughly 80 percent survived the operation, and within...
  • Marijuana's effects on young brains diminish 72 hours after use, research says

    (CNN)Marijuana is notorious for slowing certain cognitive functions such as learning, memory and attention span (maybe that's why they call it "dope"?). But new research in young people suggests that these cognitive effects, while significant, may not persist for very long, even among chronic users. The meta-analysis, published Wednesday in the journal JAMA Psychiatry, combines data from 69 previous studies that look at the effects of heavy cannabis use on cognitive functioning in adolescents and young adults. It found that those young people who identified as heavy marijuana users scored significantly lower than non-users in a variety of cognitive domains...

    President Trump earned a perfect score on a medical test that is used to detect early signs of dementia or Alzheimer's disease. The test, called the Montreal Cognitive Assessment, was conducted during his routine physical on Friday, at the insistence of the president, who wanted to tamp down rumors about his mental abilities that have surfaced from his critics. Dr. Ronny Jackson, the White House doctor who conducted the exam, said that he did not believe it was necessary because he hadn't noticed any issues with Trump's memory after spending the past year with him. The doctor's quarters are in...

    An international team of scientists have confirmed the discovery of a major cause of dementia, with important implications for possible treatment and diagnosis. Professor Garth Cooper from The University of Manchester, who leads the Manchester team, says the build-up of urea in the brain to toxic levels can cause brain damage - and eventually dementia. The work follows on from Professor Cooper's earlier studies, which identified metabolic linkages between Huntington's, other neurodegenerative diseases and type-2 diabetes. The team consists of scientists from The University of Manchester, the University of Auckland, AgResearch New Zealand, the South Australian Research and Development Institute,...

    Loose dentures? More like loose screws. Donald Trump was slurring his words pretty good last week for a guy who fancied himself an expert when it came to Hillary Clinton's alleged brain damage. What would he make of his own slurred speech and bizarre behavior? Brain damage from inhaling too much hairspray? A brain tumor from the weight of that massive combover sitting on top of his head like a live farm animal? Simply slurred speech because his thoughts are so fantastic that his mouth can't keep up? Maybe it's a pesky case of dysphasia, the condition Trump's used-to-be-spokesperson Katrina...

    Doctors treating the U.S. embassy victims of suspected attacks in Cuba have discovered brain abnormalities as they search for clues to explain hearing, vision, balance and memory damage...It’s the most specific finding to date about physical damage, showing that whatever it was that harmed the Americans, it led to perceptible changes in their brains. The finding is also one of several factors fueling growing skepticism that some kind of sonic weapon was involved. Medical testing has revealed the embassy workers developed changes to the white matter tracts that let different parts of the brain communicate, several U.S. officials said, describing...

    I’m so old that I remember when Democrats were all about lower taxes for the working class and could care less about the national debt. Now - of a sudden - they are all concerned about the deficit and don’t want to lower taxes for the middle class? It’s enough to make me ask if I’m totally misremembering; to give me pause and wonder if I’m showing the first signs of dementia. Perhaps I should have my brain examined.The drawing above came to me courtesy of American Digest’s impresario, Gerard Vanderluen. He scours the corners of the innertubes for facts...

    The researchers, who examined the brains of 199 females and 110 males, found that individuals with better wiring of the anterior insula and the anterior cingulate cortex - two areas of the brain associated with the cognitive processing of task-relevant information - demonstrated better cognitive function. The university defined intelligence as the 'general mental capability that involves the ability to reason, to think abstractly, and to learn quickly from experiences,' and consulted graph theoretical network analysis methods to draw their conclusions. 'The different topological embedding of these regions into the brain network could make it easier for smarter persons to...

    It’s an open secret that Silicon Valley exploits our tendency to seek the neurological rewards delivered by the likes, comments and mentions that pop up on our internet-connected devices. As such, smartphone use can certainly feel like it’s habit-forming. But a desire to engage with technology — and even what could be seen as compulsive use — is not the same thing as addiction, despite what a new study claiming that smartphone addiction changes our brains claims.In the new paper, presented Thursday at the annual meeting of the Radiological Society of North America, a team of radiologists at Korea University...

    A “memory prosthesis” brain implant has enhanced human memory for the first time. The device is comprised of electrodes implanted in the brain, and is designed to mimic the way we naturally process memories, and can boost performance on memory tests by up to 30 per cent. A similar approach may work for enhancing other brain skills, such as vision or movement, says the team behind the work. “We are writing the neural code to enhance memory function,” says Dong Song of the University of Southern California, who presented the findings at the Society for Neuroscience meeting in Washington DC...

    Blocking TRF1 interrupts tumor growth and increases survival in various mouse models of glioblastoma. This is a potential therapeutic option for a disease for which there are no curative treatments. The Telomere and Telomerase Group at the Spanish National Cancer Research Centre (CNIO) has shown that it is possible to block the growth of human and murine glioblastoma in mouse models by blocking the TRF1 protein; an essential component of the telomere-protective complex known as shelterin. The study, published in Cancer Cell, describes a new and promising way to combat this type of brain tumour, considered one of the most...

    Houston is barely beginning to dry out from Hurricane Harvey, and Florida faces a massive rebuilding effort after the Irma catastrophe. So why isn’t the public heeding scientists and demanding climate action by politicians that could help deal with these destructive extremes? You can point fingers at the influence of fossil fuel companies, at misinformation from climate deniers and at political obstructionism, notably from a fragmented Republican party. But a much deeper force is also at work: the way our brains function. Humans aren’t well-wired to act on complex statistical risks. We put a lot more emphasis on the tangible...
