'Incredibly rare' white baby sea turtle pops out of the sand on South Carolina beach
An “extremely rare” white baby sea turtle was found Sunday on a beach 25 miles south of Charleston, South Carolina, according to Kiawah Island town officials.“You can imagine the excited ‘oohs’ and the ‘aahs’ from the guests, including some College of Charleston students, when the (beach) patroller found a lone, leucistic hatchling in the nest,” town officials wrote on Facebook. “It was a first for everyone.”Leucism is a condition that decreases color pigmentation, experts say, often making an animal appear white or spotted.“Leucism is different from albinism, as albino animals have a complete...

Coronavirus reinfections are real. Here's what that means for controlling the pandemic.
The first confirmed case of an American who got COVID-19 twice adds to scant but mounting evidence that people can be reinfected with the coronavirus — and get sicker than during the initial bout.The 25-year-old Nevada man, who had no known immune problems, got a mild case of COVID-19 in April. About a month later, he was diagnosed again and needed hospitalization and oxygen, according to the report published Monday in Lancet Infectious Diseases.The authors say at least three other confirmed cases have been published worldwide, including the first in Hong Kong barely two months ago. But the CO...

Zoo scientists revive cells from 40-year deep freeze to clone endangered horse
SAN DIEGO — Kurt looks and acts like any other young horse. He scampers and strides on springy legs, testing their strength. When it’s time to recharge, he nuzzles up to his mother for some nourishing milk.But Kurt is no ordinary horse. Kurt is a clone.The 2-month-old colt is a Przewalski’s horse, a species native to central Asia that once went extinct in the wild and is still critically endangered, with only about 2,000 remaining.San Diego Zoo Global researchers have high hopes that Kurt can help turn things around for his species. He was cloned from skin cells taken from a stallion in 1980 a...

Miami-Dade is one storm away from a housing catastrophe. Nearly 1 million people are at risk
MIAMI — As the tail end of one of the most active hurricane seasons in history nears, Miami-Dade County appears once again poised to emerge unscathed. The region dodged hurricanes and tropical storms that posed a potential threat to South Florida. But what will happen when that luck runs out?Housing advocates have long feared that the city is one storm away from disaster; nearly a third of all housing structures in Miami-Dade County built before 1990 are at risk of wind damage, mold contamination and even complete devastation from a hurricane.According to U.S. Census Bureau figures, nearly 1 m...
From community college to COVID research, he followed a nontraditional path to fighting the virus
PHILADELPHIA — When Yaya Dia comes home from a long day at work, hungry for a steaming plate of his mother’s fish with rice, his little brothers don’t let him sit down without a big hug.“Are you a doctor yet?” the youngest, 10-year-old Abou, will often ask.“I’m getting there,” replies Dia, 29.He is on a longer journey than most. He spoke no English when he immigrated at age 9 from the West African nation of Burkina Faso, and at first, was indifferent about school amid the unfamiliar tumult of Philadelphia. He went to an automotive vocational school, considered a career in the military, then wa...

Rising waters threaten Great Lakes communities
Along a shoreline that stretches farther than the combined length of the Atlantic and Pacific coasts, waters driven by climate change have risen as much as 6 feet in less than a decade, washing away houses, destroying roads and threatening critical infrastructure such as water treatment plants in towns large and small.The ongoing disaster striking the coastal communities of the Great Lakes hasn’t captured national attention like hurricanes and wildfires in other parts of the country. But from Duluth to Chicago to Cleveland to Buffalo, leaders are reeling from untold billions in damage — and th...
Healthy corals in Biscayne Bay surprised scientists. They may help reefs survive
MIAMI — During a scouting mission to check on coral colonies in inshore Biscayne Bay last year, Caroline Dennison and a few other marine biology graduate students found something astounding: healthy populations of brain corals.There were no signs of white spots or bleaching and the vivid yellowish brown colors indicated that the corals were untouched by yet another mysterious disease that’s ravaging reefs along the Florida coast. Even more extraordinary was that these corals were thriving in shallow and warm water right off the seawall at Bill Baggs Cape Florida State Park, near a bustling sea...
How to conduct an engaging lab experiment in the time of COVID: Brew beer
PHILADELPHIA — The 22 students in the La Salle University microbiology class had been brewing their first batch of beer for the last two weeks, and it was time to taste it.Senior Austin Taylor, participating on the class Zoom call, took a swig from his jar and grimaced.“Oh, oh, that’s gross,” the senior biology major from Woodbridge, New Jersey, said, putting his hand over his mouth as if he wasn’t sure he could swallow it. “That was nasty. I don’t recommend that.”His teacher, assistant professor Brian DeHaven, laughed and told him not to worry. “So was mine,” DeHaven said.Brewing the perfect ...

Airlines say flying is safe in COVID-19 era, but study reveals potential for superspreader disaster
SAN JOSE, Calif. — How risky is it to fly during the coronavirus pandemic?For clues, consider the travel histories of two of the country’s top infectious disease experts, each with parents on the other side of the country. One hasn’t flown since January when the new coronavirus was just emerging as a global threat.The other just flew back to San Francisco after visiting his 90-year-old father in Florida last month — wearing a face shield and removing his medical-grade N-95 respirator mask for just 30 seconds to chug some water and pretzels — and “felt pretty safe” to see everyone else wearing ...
