Study links lightning with gamma rays inside clouds

Study links lightning with gamma rays inside clouds

Science
June 25 (UPI) -- Weak gamma-ray glows appear to precede lightning strikes and accompanying gamma-ray flashes under certain conditions. Over the last several years, researchers at the University of Tokyo worked with schools and businesses in Kanazawa, Ishikawa Prefecture, in central Japan, to install a network of radiation monitors for studying lightning. "Forever, people have seen lightning and heard thunder. These were the ways we could experience this power of nature," University of Tokyo graduate student Yuuki Wada said in a news release. "With the discovery of electromagnetism, scientists learned to see lightning with radio receivers. But now we can observe lightning in gamma rays -- ionizing radiation. It's like having four eyes to study the phenomena." Scientists used observations ...
Study links low-dose aspirin to bleeding inside the skull

Study links low-dose aspirin to bleeding inside the skull

Health
May 13 (UPI) -- People without a history of heart disease and stroke who took low-dose aspirin were more likely to experience bleeding inside the skull, according to a new study. Historically, the use of low-dose aspirin has been recommended for older adults as a way to reduce the risk of stroke or heart attack. The over-the-counter pain medication can prevent blood clots from forming. When fatty deposits called atherosclerotic plaques form in arteries, pieces of plaque can break off and trigger clotting, preventing adequate blood flow to the brain or heart. The use of low-dose aspirin has garnered criticism in recent years. Several recent studies have shown the drug increases the risk of heavy bleeding. The latest research, published this week in the journal JAMA Neurology, suggests reg...
Getting inside the head of the man who was Frank Sidebottom

Getting inside the head of the man who was Frank Sidebottom

Entertainment
In the 1980s and '90s, Frank Sidebottom was a giant-headed, cartoon-eyed, cult comedy hero - but few knew who was behind the mask. A documentary is now telling his full story for the first time.When his head was on, the man behind Frank Sidebottom would never answer to his "real" name."If he was wearing the head, you couldn't talk to him as Chris," says older brother Martin. "Even me.""It was like method acting really," reflects BBC Radio 2 and 6 Music DJ Mark Radcliffe, who was in Sidebottom's band. With his absurd, anarchic humour and childlike innocence, Sidebottom was a hit with Saturday morning TV audiences and late-night pub crowds alike.He and the world he created...
Fat inside body worse for health, study says

Fat inside body worse for health, study says

Health
Feb. 1 (UPI) -- The fat that poses the biggest danger to a person's health isn't visible outside of the body, but inside of it, a new study says. Exercise and medicine are the most helpful for getting rid of visceral fat, according to a study published Friday in Mayo Clinic Proceedings. "Visceral fat can affect local organs or the entire body system. Systemically it can affect your heart and liver, as well as abdominal organs," said Ian J. Neeland, assistant professor of internal medicine University of Texas Southwestern Medical Center and study senior author, in a press release. "When studies use weight or body mass index as a metric, we don't know if the interventions are reducing fat everywhere in the body, or just near the surface." Visceral fats are also known as an "active organ," w...
Possible building block of life detected inside distant star

Possible building block of life detected inside distant star

Science
Jan. 23 (UPI) -- Scientists have detected the prebiotic molecule glycolonitrile inside a distant star for the first time. Researchers think the molecule may have played a role in the emergence of life on Earth. Glycolonitrile is considered an important precursor to adenine, one of the nucleobases that forms both DNA and RNA. Astronomers detected the organic chemical's signature inside a solar-type protostar named IRAS16293-2422 B. By studying the chemical makeup of infant stars, still enveloped by a thick blanket of gas and dust, scientists can gain a better understanding of how the chemical ingredients necessary for life come to exist inside a young stellar system. Researchers in Europe and the United States were able to locate glycolonitrile among the spectral signature recorded by the ...
