After working with wounded Israeli soldiers in the 1970s, he developed a holistic approach to helping patients regain some semblance of the life they had before.
A growing number of professional football players have been diagnosed with a neurodegenerative disease called chronic traumatic encephalopathy (CTE), likely the result of suffering repeated concussions or similar repetitive brain trauma over the course of their careers. It’s also common in other high-contact sports like boxing, Muay Thai, kickboxing, and ice hockey. We might find clues about the underlying physics by studying the deformation of egg yolks, according to a new paper published in The Physics of Fluids. This in turn could one day lead to better prevention of such trauma.
Egg yolk submerged in liquid egg white encased in a hard shell is an example of what physicists call “soft matter in a liquid environment.” Other examples include the red blood cells that flow through our circulatory systems and our brains, surrounded by cerebrospinal fluid (CBR) inside a hard skull. How much a type of soft matter deforms in response to external impacts is a key feature, according to Villanova University physicist Qianhong Wu and his co-authors on this latest study. They point to red blood cells as an example. It’s the ability of red blood cells to change shape under stress (“erythrocyte deformability“) that lets them squeeze through tiny capillaries, for instance, and also triggers the spleen to remove red blood cells whose size, shape, and overall deformability have been too greatly altered.
A.J. Edelman walked away from the hazards of sledding sports after he competed for Israel in the skeleton at the 2018 Winter Games. Now he is trying again in a bobsled.
If approved by a federal judge, the settlement agreement in a class-action lawsuit could result in thousands of veterans gaining access to the Department of Veterans Affairs’ full array of benefits.
In skeleton, the headfirst Olympic sledding sport, the opportunity for unlimited training on the track can be a huge advantage. But Canadian Olympians who had such access believe it was bad for their brains.
