Trump S Immigration Policies Will Make The Coronavirus Pandemic Worse

Pandemics have a way of testing us. Throughout history, societies have responded to plagues by blaming immigration and minority populations. Such approaches usually make matters worse. If pandemics reveal anything, it is that our health depends in no small measure on how we treat the most vulnerable among us. The Covid-19 outbreak is now testing the U.S. Some recent and not-so-recent immigration policies do not put us in a good position to combat it....

Turn Me On Dead Man

In September 1969, as I began ninth grade, a rumor circulated that the Beatles’ Paul McCartney was dead, killed in a 1966 automobile accident and replaced by a look-alike. The clues were there in the albums, if you knew where to look. Sgt. Pepper’s Lonely Hearts Club Band’s “A Day in the Life,” for one, recounts the accident: He blew his mind out in a car / He didn’t notice that the lights had changed / A crowd of people stood and stared / They’d seen his face before / Nobody was really sure if he was from the House of Lords....

Viral Gene Appears Crucial To Mammalian Reproduction

A viral gene embedded in the sheep genome plays an essential role in the growth of the animal’s placenta, according to a study of impregnated sheep. The result strengthens the case that similar viral genes play the same role in mice and people. Up to 10 percent of a mammal’s genome is made up of DNA captured from retroviruses, which insert their DNA into the host genome and sometimes lose the ability to get back out of the cell....

Watching World Series Causes Drop In Hospital Visits

What factors determine whether a medical emergency is truly an emergency? According to a new study, the answer depends on how well your favorite baseball team is doing. A report published in the October issue of the Annals of Emergency Medicine reveals that the number of visits to emergency rooms in Boston-area hospitals was inversely related to how well the Red Sox performed in the 2004 World Series. Previous studies had suggested a relationship between important sporting events such as the Super Bowl and hospital visits....

When Peanut Allergy Comes From A Blood Transfusion

The origin of a food allergy usually remains a mystery. Not so for an eight-year-old boy who received a blood transfusion unexpectedly brimming with antibodies against salmon and peanuts—two foods he had routinely consumed in the past. A few weeks after receiving transfusions, when he had a serious allergic reaction within 10 minutes of eating salmon and another after he ate a chocolate peanut butter cup, his doctors soon identified the source of the problem....

Wrens Teach Eggs To Sing

Mothers usually set about teaching their offspring the moment they’re born. But the females of one Australian bird can’t wait that long. Superb fairy-wren (Malurus cyaneus) mothers sing to their unhatched eggs to teach the embryo inside a ‘password’ — a single unique note — which the nestlings must later incorporate into their begging calls if they want to get fed. The trick allows fairy-wren parents to distinguish between their own offspring and those of the two cuckoo species that frequently invade their nests....

A Friend Like Me When Given More Choices People Pick Friends Similar To Themselves

Whether it’s deciding what to eat or where to live, we like to have options. And the more options we have, the more varied our choices will be—right? When it comes to picking our friends, perhaps not. A new study published September 21 in Group Processes & Intergroup Relations suggests that when people are able to choose friends from a larger, more diverse group, they pick pals who are most similar to themselves....

A Proposed Storm Surge Barrier Could Protect Texas From Storms Like Laura

If Hurricane Laura shifts west and lands squarely on the Texas coast, it will be the fifth deadly hurricane to strike the Lone Star State since 2000. That’s far too soon for Texas and federal partners to complete a storm surge protection system designed to shield the Lone Star State from major hurricanes. But they’re hoping the multibillion-dollar project might be done in time for a sixth major hurricane. Or maybe a seventh....

A Sense Of Time Requires A Sense Of Space

We often think of the abstract idea of time in the concrete terms of space, saying we are “looking forward to the weekend” or “putting the past behind us.” These adages may be more than just metaphors. A study published in January in Psychological Science suggests that thinking of space may be a necessity to conceptualize time. When people’s minds are not able to accurately understand space, researchers found, they have difficulty with time as well....

Bad Habits May Cause Older Drivers Mistakes

MR. MAGOO, a cartoon regular of early television, was notorious for his hazardous driving. He was a retiree, befuddled and extremely nearsighted, yet he continued to drive despite these obvious failings. In the opening sequence to his long-running show, he had run-ins with a railroad train, a haystack and several barn animals, a roller coaster, a fire hydrant, a mud hole and a high voltage line—all while honking his horn and shouting, “Road hog!...

Brain Makeover

Practice makes perfect—and it rewires the brain, as many studies have shown. But sometimes hours of practice can take these brain changes too far, as happens in musician’s dystonia, when the boundaries between muscles blur in the brain and precise movements are no longer possible. In pianists, for example, the fingers might clutch inward involuntarily every time they attempt to strike a key. This condition takes years to develop, but new research suggests a treatment that takes only 15 minutes can reorganize the brain and allow musicians to play again....

Forecasts Of Epilepsy Seizures Could Become A Reality

Seizures are like storms in the brain—sudden bursts of abnormal electrical activity that can cause disturbances in movement, behavior, feelings and awareness. For people with epilepsy, not knowing when their next seizure will hit can be psychologically debilitating. Clinicians have no way of telling people with epilepsy whether a seizure will likely happen five minutes from now, five weeks from now or five months from now, says Vikram Rao, a neurologist at the University of California, San Francisco....

Mental Health Care Should Be Available For All Not A Luxury

For more than 25 years, Richard Youins struggled to find help with his drug addiction. Youins is from New Haven, Conn., home to both Yale University and a number of less affluent neighborhoods—his community has been shaken by murders and drug-related crimes during the pandemic. Substance use clinics and treatment sites were available, but he felt the care they provided overlooked who he was as a person. The needs “of our community weren’t being addressed,” says Youins, who is Black....

New Highly Radioactive Leak At Japan S Fukushima Plant

By Mari Saito TOKYO (Reuters) - The operator of Japan’s Fukushima nuclear plant said on Thursday that 100 metric tons of highly contaminated water had leaked out of a tank, the worst incident since last August, when a series of radioactive water leaks sparked international alarm. Tokyo Electric Power Co told reporters the latest leak was unlikely to have reached the ocean. But news of the leak at the site, devastated by a 2011 earthquake and tsunami, further undercut public trust in a utility rocked by a string of mishaps and disclosure issues....

Quick Action Slowed Spread Of 1918 Flu

U.S. cities slowed the spread of the 1918 pandemic flu by measures such as closing schools and churches and banning mass gatherings, thereby reducing the severity of outbreaks in certain locations, according to a pair of new studies. A few cities appear to have reduced flu transmission so well that they lifted the control measures too early and allowed the virus to spread rapidly again. Researchers say that such practices could, in principle, limit the death toll of a future pandemic, but authorities would have to implement them early and long enough....
