Some U.S. colleges are converting empty dorms into temporary housing for coronavirus patients.

That could prove crucial if hospitals nationwide are swamped with a surge of coronavirus cases that push them beyond their capacity, the Associated Press reported.

On Wednesday, Tufts University in Massachusetts said it's making hundreds of vacant dorm rooms available in coming weeks to help relieve "unprecedented stress" on the health care system.

The school's president called on other U.S. universities to do the same, saying they have a civic duty to help in times of crisis, the AP reported.

Middlebury College in Vermont is offering some of its buildings, and New York University is asking students who live near campus clear out their dorm rooms in case they're needed to house coronavirus patientsEver get a paper cut or nick yourself while shaving? When that happens, a blood clot saves the day. It quickly stops the bleeding, and when it's done its job, it usually breaks up. Sometimes, though, things can go wrong.

When blood clots don't fall apart, they can be dangerous and lead to serious medical conditions. You can get them in blood vessels in just about any part of your body. They’re most likely to affect a leg, especially if you sit for long periods of time.

You might get a clot in your arteries, which carry oxygen in your blood from your heart to all the cells of your body. The result can be really serious. It can keep oxygen from getting to your heart, lungs, or brain, and cause a life-threatening emergency, like a heart attack or stroke.

You could also get a clot in the veins that carry blood back to your heart. When that happens, symptoms usually come on more gradually, but can still mean trouble.

If you learn the warning signs, you'll know when to get quick medical help that can make a huge difference in keeping you out of the danger zone.

When a blood clot forms in one of the deep veins in your arm or leg, way beneath your skin's surface, it could be something called a deep vein thrombosis (DVT). That's dangerous because the clot could travel to your heart or lungs.

You're more likely to get a DVT if you've haven't moved around for a long time, say after surgery or during a long plane trip. Get medical help right away if you notice any of these symptoms:

Body temperature: What is the new normal?

Many researchers have argued that the accumulation of toxic beta-amyloid in the brain causes Alzheimer’s. However, a new study offers some evidence contradicting this sequence. New research is questioning the predominant hypothesis that a buildup of beta-amyloid causes Alzheimer’s disease. Alzheimer’s disease affects over 5.5 million people in the United States and millions more around the globe. Yet, researchers are still at a loss as to why this condition — which is characterized by memory impairment and many other cognitive problems — occurs in the first place. And until they fully understand the cause, investigators will remain unable to devise a cure. So far, the prevailing hypothesis among experts has been that the excessive accumulation of a potentially toxic protein — beta-amyloid — in the brain causes Alzheimer’s. Researchers have argued that beta-amyloid plaques disrupt the communication between brain cells, potentially leading to cognitive function problems. Now,...

Pharmaceutical industry affected In fact, it is to successful private pharmaceutical companies such as Cipla, Sun Pharma and Dr. Reddy’s that the Indian authorities immediately turned to ensure the availability of certain products needed in the event of a major outbreak. The government has restricted exports of about 20 products including protective equipment and some medical ingredients, such as Lopinavir and Ritonavir. These antiretrovirals are currently being used together against HIV and are being touted by Indian doctors, like their Chinese counterparts, as useful to treat the symptoms of COVID-19. Despite assurances from large India pharmaceutical companies about the strength of their stockpiles, however, fears which prompted the government to restrict exports are not unfounded. Between 80-85% of the active ingredients used in drugs assembled in India come from China, 25% of which are from the Hubei region, the epicentre of the epidemic. To cope with the disruption of the...
