Old red dye shows promise as new cancer foe

By Bill Berkrot NEW YORK (Reuters) - Modern cancer drugs supercharge immune systems, target specific gene mutations and pack modified viruses into vaccines. Rose Bengal, a cheap industrial chemical that turns yarn and food bright red, has been used as a diagnostic staining agent for some time. Now, some scientists are looking at its potential to fight various forms of cancer.

Gas from thawing permafrost could add further to global warming, study says

By Ellen Wulfhorst NEW YORK (Thomson Reuters Foundation) - Arctic permafrost that is thawing due to global warming is releasing greenhouse gases, further compounding the problem of climate change, according to a study released on Thursday. As the permafrost thaws, changes in the way its soil microbes function and the soil carbon decomposes add to the emissions of carbon dioxide and methane into the atmosphere, according to the study by U.S. and Chinese scientists.

California methane leak was biggest ever in U.S., scientists say

By Steve Gorman LOS ANGELES (Reuters) - The months-long natural gas leak that forced thousands of Los Angeles residents from their homes ranks as the largest known accidental methane release in U.S. history, equal to the annual greenhouse gas emissions of nearly 600,000 cars, scientists reported on Thursday. At its peak, 60 tons per hour of natural gas was spewing from a ruptured underground pipeline at the Aliso Canyon storage field, effectively doubling the methane emissions of the entire Los Angeles metropolitan area, the researchers said.

Astronaut heading home next week after record-long U.S. spaceflight

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - NASA astronaut Scott Kelly, who returns next week after nearly a year aboard the International Space Station, said on Thursday the secret to enduring the longest U.S. spaceflight is marking individual milestones, not ticking days off the calendar. Since arriving at the space station on March, 27, 2015, Kelly and Russian cosmonaut Mikhail Korneinko have served with eight different crewmates, unpacked six cargo ships, weathered two botched supply runs and participated in dozens of science experiments. Kelly also made three spacewalks outside the $100 billion station, which flies about 250 miles (400 km) above Earth, and Kornienko made one.

At its peak, 60 tons per hour of natural gas was spewing from a ruptured underground pipeline at the Aliso Canyon storage field, effectively doubling the methane emissions of the entire Los Angeles metropolitan area, the researchers said. The stench of fumes from the site sickened scores of people and prompted the temporary relocation of more than 6,600 households from the northern Los Angeles community of Porter Ranch at the edge of the gas field.

Food for Thought: Human Teeth Likely Shrank Due to Tool Use

Wisdom teeth may have shrunk during human evolution as part of changes that started with human tool use, according to a new study. The research behind this finding could lead to a new way of figuring out how closely related fossil species are to modern humans, scientists added. Although modern humans are the only surviving members of the human family tree, other species once lived on Earth.

Baby Gorilla Thriving After Rare C-Section Delivery

A baby gorilla was recently delivered by a rare emergency caesarean procedure, after her mother developed a potentially life-threatening condition, according to officials at the Bristol Zoo Gardens in the United Kingdom. The baby western lowland gorilla was born on Feb. 12, weighing in at 2 pounds and 10 ounces (just over 1 kilogram), and zoo officials said she initially needed help breathing on her own. Animal keepers are now hand-rearing the baby gorilla and report that she is doing well, though the animal will not yet be on view to the public, according to the Bristol Zoo.

Bizarre Solar-Powered Worms Are Social Sunbathers

A serendipitous observation and a new series of computer simulations reveal that the mint-sauce worm is a social animal. The worms would swim next to one another in parallel and form little "flotillas," Franks said.

Dinosaur Was Giving 'the Finger' Due to Bone Deformity

The beast set a record for most upper-body injuries ever seen on a theropod dinosaur (a group of bipedal, mostly meat-eating dinosaurs), the researchers said. The previous record-holder is Sue, the famous Tyrannosaurus rex on display at the Field Museum of Natural History in Chicago, who has a total of four bone injuries on its shoulder and forelimbs. "We not only exceeded the record [for theropod injuries], we doubled it," said study co-author Phil Senter, a professor of biology at Fayetteville State University in North Carolina.
