You probably don't think of ice cream as a pain-inducing substance, but enjoying those first few spoonfuls of the frozen treat too quickly might bring on a sudden, stabbing pain in the forehead known as "brain freeze." The pain of brain freeze can begin within seconds of being exposed to cold temperatures, and the intensity of the pain peaks very quickly, often within seconds, said Dr. Stephanie Goldberg, a neurologist and headache specialist at Tufts Medical Center in Boston. Why do you get it? Brain freeze, also called an "ice-cream headache," is known in medical terms as a "cold-stimulus headache," Goldberg said. It's a common phenomenon that affects people of all ages, but doctors aren't quite sure why it happens. [Ouch: 10 Odd Causes of Headaches] For this type of headache, the main trigger is any kind of exposure to a significantly cold temperature, Goldberg said. It's not only caused by an internal trigger, like eating frozen treats too quickly; it can also be caused by an … [Read more...] about What Is Brain Freeze?

source Charlotte Hu / Business Insider An inventor’s treasure trove lies tucked away in a remote part of Brooklyn. New Lab, in the Brooklyn Navy Yard, is an oasis for artists, engineers and entrepreneurs, serving as a hub where they can quickly concept, build and test products and ideas. The two-year-old New Lab, which is the home to over 130 NYC startups today, was once Building 128, a machine shop that created parts for ships used in both World Wars, and had since fallen into disrepair. New Lab’s creators, David Belt and Scott Cohen, turned the 84,000 square-foot facility into a space that would help the entrepreneurs translate their ideas into physical products. Today, the site houses a 3D printing lab, laser cutters, wood and metal shops, a fabrication shop, an electronics shop, and casting and finishing equipment. This full set of equipment, worth $5 million total, gives creators everything they need to develop a working prototype. The shops … [Read more...] about Take a look inside a gorgeous inventor’s paradise in a remote part of Brooklyn that used to be a deserted, rotted-out machine shop
Feelings of sadness or anxiety might be linked to increased "chitchat" between two areas of the brain, a new study suggests. In the study, published today (Nov. 8) in the journal Cell, a group of researchers listened in on electrical conversations in the brain — in other words, the signals that brain regions send to one another. When a person is feeling down, they found, the communication increased between brain cells in two specific regions of the brain involved in memory and emotion. It's unclear whether this increased brain communication is a cause or an effect of a bad mood, the researchers noted. However, the findings allowed them to home in on the part of the brain where the action is. [5 Ways Your Emotions Influence Your World (and Vice Versa)] What is clear, however, is that anxiety, depression and mood have physical manifestations in the brain. "For many patients, it is very important to know that when they are feeling depressed, it is due to something measurable and … [Read more...] about What Does Sadness Look Like in the Brain?
A rapidly progressing “polio-like” illness is leaving children in numerous states paralyzed – and experts aren’t sure what’s causing the kids to fall ill.The rare disease, called Acute Flaccid Myelitis (AFM), causes an “inflammation of spinal cord” that resembles cases of polio from the 20th century, Johns Hopkins associate professor of neurology and pathology Dr. Carlos A. Pardo told the Daily News.Cases of AFM have recently been reported in at least five states: Minnesota, Washington, Illinois, Colorado and Pennsylvania.The exact cause of AFM is unknown — it may be a new virus that some children do not have enough immunity to combat and therefore have a bad reaction where the nervous system fails, or the virus attacks the spinal cord directly.“The CDC found evidence of enterovirus D68 in respiratory samples in approximately 20% of patients affected, and other viruses in another 20%, though in the majority of cases a trigger was … [Read more...] about Everything you need to know about the ‘polio-like’ illness popping up around the U.S.
