Biologists locate baby white sharks' hangout in North Atlantic

Biologists locate baby white sharks' hangout in North Atlantic

Science
July 18 (UPI) -- With the help of next-generation satellite and acoustic technology, marine biologists have identified the migration patterns and hangouts of baby white sharks in the North Atlantic. Researchers have long suspected that the New York Bight, a seafloor indentation running from New Jersey's Cape May Inlet to Montauk Point on the eastern tip of Long Island, serves as a nursery for newborn and juvenile white sharks. But a nursery must meet three specific criteria: it must host higher densities of young sharks; it must be used year after year, over years; and it must be used as a residency for extended periods. Until now, scientists have only been able to confirm the New York Bight's adherence to the first two criteria. However, the recent tagging and tracking of 10 baby white ...

Later, White House Press Secretary Sarah Sanders said Mr Trump was saying "no" to answering further questions.It comes amid a flurry of criticism over his recent comments about Russia. "The president and his administration are working very hard to make sure that Russia is unable to meddle in our elections as they have done in the past," Mrs Sanders said at a news briefing on Wednesday. What's the latest confusion? Ho...
Embryo breakthrough 'can save northern white rhino'

Embryo breakthrough 'can save northern white rhino'

Science
The seemingly "disastrous" story of the world's most endangered mammal - the northern white rhino - could be rewritten by IVF, scientists claim. They used the method to produce rhino embryos with sperm from two dead males.The embryos were made using eggs from a closely related sub-species, but the scientists say the method could save the northern white rhino. One of the team said he hoped a baby that's fully northern white rhino would be born "within three years". This could provide a way of "rescuing valuable genes" from a sub-species that is already functionally extinct; the last male northern white rhino, named Sudan, died earlier this year at the age of 45. Only two females now remain, but the researchers who carried out this...

Stress triggers white blood cells, boosts heart attack risk for diabetics

Stress triggers white blood cells, boosts heart attack risk for diabetics

Health
June 26 (UPI) -- Stress hormones and white blood cells can be good or bad -- they can join together to fight infection and heal injuries, but they also can lead to heart attacks. Researchers at the University of Pittsburgh School of Medicine studied how white blood cells can rupture and hemorrhage in people with diabetes, because they are overactive, and cause inflammation in plaques in blood vessels. Findings from the new study were published Tuesday in the journal Immunity. "If the rupture occurs in the coronary artery, the person has a heart attack. If the rupture occurs in the carotid artery, it causes a stroke," Dr. Partha Dutta, an assistant professor of medicine at Pitt's School of Medicine, said in a press release. There are more than 100 million adults in the United States livin...
