Are Europeans Better than Americans at Forecasting Storms? Scientific American
As Hurricane Joaquin gained wind over the Atlantic today, meteorologists scrambled to figure out where it’s headed next, leaving the rest of us scratching our heads. Will this storm currently punishing the Bahamas turn west and make landfall along the East Coast, or will it turn east and leave us alone? Both of these forecasts aired today. The American Global Forecasting System (GFS) predicted the storm would make landfall on the U.S. while the European Center for Medium-Range Weather Forecast (ECMWF) expected Joaquin to skip the East Coast entirely. Meanwhile, the hurricane grew from Category 3 to Category 4 on the Saffir-Simpson scale, with winds clocked at around 125 mph. Click to read more
Melatonin Linked to Seasonal Relapses of Multiple Sclerosis, Scientific American
Multiple sclerosis (MS) relapses are known to swing with the seasons. Scientists have attributed these fluctuations to the rise and fall of vitamin D production, which is triggered by exposure to seasonal sunlight. Now a new study suggests that melatonin, a hormone that regulates your internal body clock and sleep cycles, could also play a protective role.
Evidence for Person-to-Person Transmission of Alzheimer's Pathology, Scientific American
Prions are the misshapen proteins that replicate by inducing normal proteins to misfold and aggregate in the brain, leading to rare diseases such as mad cow and kuru. In recent years, scientists have discovered that similar processes of protein misfolding are at work in many neurodegenerative disorders, including Alzheimer’s, Parkinson’s and Lou Gehrig’s disease. Now, a study in Nature reveals the first evidence for human-to-human transmission of the misfolded proteins that underlie the pathology of Alzheimer’s disease. Click to read more
There is an established notion of the "happy idiot" — someone who doesn’t know a lot, knows he doesn’t know a lot, and doesn’t care. Think about Joey Tribbiani from Friends or Fry from Futurama. Though simple-minded and rather oblivious to their surroundings, both characters tended to come out on top. New research suggests that there may be something to this frequently invoked trope. Not knowing a lot — and being aware of your own ignorance — can make decisions easier and, as a result, lead to greater happiness.
Antimatter is the stuff of science fiction. In the book and film Angels and Demons, Professor Langdon tries to save Vatican City from an antimatter bomb. Star Trek’s starship Enterprise uses matter-antimatter annihilation propulsion for faster-than-light travel. But antimatter is also the stuff of reality. Antimatter particles are almost identical to their matter counterparts except that they carry the opposite charge and spin. When antimatter meets matter, they immediately annihilate into energy. While antimatter bombs and antimatter-powered spaceships are far-fetched, there are still many facts about antimatter that will tickle your brain cells.
