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 ...
Blue Jays start series with Rays after sweeping Orioles

Blue Jays start series with Rays after sweeping Orioles

Sports
The Tampa Bay Rays and the Toronto Blue Jays are now within a half game of each other in the American League East standings, though they've come from wildly different directions. The Rays (29-35) have lost nine of 10 games, including three of four in a weekend series with the Seattle Mariners. The Blue Jays (30-35) come into Tropicana Field with the momentum of a four-game sweep against the last-place Baltimore Orioles, who are a full 10 games back of both teams. The schedule is oddly stacked, such that the two division rivals have only played three times in the opening third of the season. They'll meet 12 times in August and September to make up for it, so this series can set the tone as both teams fight to get back to .500. The Rays lead the majors with 17 one-run losses, including ...
Study confirms link between gamma rays, lightning strikes

Study confirms link between gamma rays, lightning strikes

Science
May 17 (UPI) -- A new survey of downward terrestrial gamma ray flashes suggests the rare electromagnetic phenomena is linked with cloud-to-ground lightning. The Telescope Array is an observatory consisting of 507 scintillation surface detectors spread out across a massive expanse of the Utah desert. Between 2014 and 2016, the array detected 10 downward terrestrial gamma ray flashes, or TGFs. The array's observations -- published this week in the Journal of Geophysical Research -- are the first to link TGFs with the beginning of lightning strikes and the first to locate the origin of a TGF inside a thundercloud. TGFs are the highest-energy light waves on the electromagnetic spectrum, and thanks to the Telescope Array, scientists are closer to understanding them. "What's really cool is tha...

Tampa Bay Rays halt Chicago Cubs' seven-game win streak

ST. PETERSBURG, Fla -- For almost half the season, Tampa Bay Rays starter Blake Snell couldn't find a way to earn a victory. Now he can't lose. Snell threw seven innings of two-hit shutout baseball, and Tampa Bay ended the Chicago Cubs' seven-game win streak, bouncing back with an 8-1 win on Wednesday night at Tropicana Field. Snell, who didn't earn a win in any of his first 15 starts this season, has now won four straight decisions and hasn't taken a loss in his last 10 starts. "I just learned I have to keep going -- you have to adapt, keep learning and keep making the adjustments you need to," Snell said after Wednesday's win. "I like the confidence that I had and kept believing in myself." The Rays (74-78) kept alive their slim hopes of an American League wild card, moving within four g...

Global food markets further threaten endangered sharks, rays

Science
Aug. 25 (UPI) -- Researchers at the University of Guelph found that the majority of shark fins and manta ray gills sold at markets around the world for traditional medicines come from endangered species.Roughly half of the world's 1,200 species of sharks and manta rays are listed as threatened by the International Union for Conservation of Nature including 20 that may not be traded internationally.The study, published today in Scientific Reports, used DNA barcoding technology and found 71 percent of dried fins and gills collected from markets and stores came from species listed as at-risk and banned from international trade. Shark finning, which is removing fins from live sharks, is illegal in Canada."Despite the controversy around shark fin soup and the fact that many of these species are...
