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.

(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.

Read More » 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. Read More » 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. Read More » Vital to food output, bees and other pollinators at risk Pesticides, loss of habitats to farms and cities, disease and climate change were among threats to about 20,000 species of bees as well as creatures such as birds, butterflies, beetles and bats that fertilize flowers by spreading pollen, it said. "Pollinators are critical to the global economy and human health," Zakri Abdul Hamid, chair of the 124-nation report, told Reuters of a finding that between $235 billion and $577 billion of world food output at market prices depended on pollinators. Ever more species of pollinators are threatened, according to the study, the first by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) since it was founded in 2012.

NASA's 2,230 pound (1,052 kilogram) Kepler Space Telescope has discovered thousands of potential planets around other stars. Now, some scientists want to go smaller: They propose searching for new worlds using miniaturized satellites that can fit in the palm of your hand. Read More » Gravitational Waves: Did Merging Black Holes Form from Single Star? Could a single, dying star give birth to not one, but two black holes? Scientists have long held different ideas about how black holes of this size get close enough to collide, but another proposal has just entered the ring: that the black holes were created, shortly before their collision, from one, massive star as it was collapsing in on itself. This new hypothesis posits that the merger of these two black holes would produce light — including, possibly, a burst of gamma-rays, the highest-energy form of light.

Researchers asked parents to remember times when they didn't feel great, but put on a "happy face" anyway when talking with their kids. Overall, parents felt that putting on a fake happy face decreased their sense of well-being and the quality of the bond they had with their kids, the researchers found.

	(Sponsor this newsletter) Bird brain? Dodos were not so dumb after all By Will Dunham WASHINGTON (Reuters) - The dodo is an extinct flightless bird whose name has become synonymous with stupidity. Scientists said on Wednesday they figured out the dodo's brain size and structure based on an analysis of a well-preserved skull from a museum collection. The research suggests the dodo, rather than being stupid, boasted at least the same intelligence as its fellow members of the pigeon and dove family. Read More » This Sugar May Be New Weapon Against Fructose This could be the implication of a new study on mice revealing that a natural sugar called trehalose prevents a diet high in fructose, or fruit sugar, from causing fatty liver disease. "In general, if you feed a mouse a high-sugar diet, it gets a fatty liver," said Dr. Brian DeBosch, a pediatric gastroenterologist at the Washington University School of Medicine in St. Louis, who led the study. The mice given the trehalose also had lower body weights at the end of the study and lower levels of circulating cholesterol, fatty acids and triglycerides, than the control mice not give the water, DeBosch added. Read More » The Science Behind Hitler's Possible Micropenis  History buffs know that Adolf Hitler had an undescended testicle, but a new review of his medical records suggests that der Führer also had other genital problems, including a condition called a micropenis. In fact, Hitler had a slew of below-the-belt problems, according to the new book, "Hitler's Last Day: Minute by Minute," (Short Books Ltd, 2015), by historians Jonathan Mayo and Emma Craigie. After reading Hitler's medical records, they said they found evidence that Hitler had a condition called penile hypospadias, in which the opening to the urethra is not at the tip of the penis, but either somewhere along the shaft or at its base, according to news reports. Read More » Kalamazoo Shooting: When Is a Person Brain Dead? But based upon the possibility that Kopf could die from her injuries, at the request of and with the permission of her parents, the team treating Kopf contacted an organ donation organization, Dr. Aaron Lane-Davies, the medical director of Bronson Children's Hospital in Kalamazoo, where Kopf is being treated, said in a statement. In the statement emailed from a hospital spokeswoman to Live Science today, Lane-Davies said that the treatment team had not yet begun to conduct a series of exams that is used to determine whether a person is brain dead. Kopf was not declared brain dead, he said.

Crew members Eugene Cernan and John Young discuss the odd whistling sound in the tape that was confidential in 1969 at the height of the space race with the Soviet Union. NASA said the tape, which was featured on the U.S. Science cable network earlier this week, was made publicly available since 1973. A NASA engineer said the unusual sound was interference between the module and the mission command center's radios.

(Reuters) - SpaceX on Wednesday postponed for at least 24 hours the scheduled Florida launch of a Falcon 9 rocket on a satellite-delivery mission and attempted return-landing at sea because of poor weather conditions, a company official said. Blast-off of the 23-story-tall booster and its payload, a SES-9 communications satellite, was rescheduled for 6:46 p.m. EST/2346 GMT on Thursday from Cape Canaveral Air Force Station, SpaceX said. The flight would be the second of more than 12 planned this year by Space Exploration Technologies, the private rocket launch service owned and operated by high-tech entrepreneur Elon Musk. Read More » Unexpected Stop for Marijuana Tourists? The Emergency Room A phenomenon called "marijuana tourism" may be leading to an uptick in marijuana-related emergency-room visits in Colorado, one of the few states where recreational use of the drug is legal, a new report finds. Since it became legal to sell marijuana in Colorado in 2014, the number of emergency-room visits possibly related to marijuana has increased more among out-of-state residents, compared with Colorado residents, according to the report. The data match what doctors have been reporting seeing, anecdotally, in emergency rooms, said Dr. Howard Kim, an emergency medicine physician at Northwestern Medicine in Chicago, and an author of the report.

The worms would swim next to one another in parallel and form little "flotillas," Franks said. Read More » 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. Read More » Boston Dynamics' New Atlas Robot Can't Be Pushed Around (Video) Robotics company Boston Dynamics released a new video yesterday (Feb. 23) showcasing its upgraded Atlas robot, and the footage features a slew of impressive (and somewhat unsettling) new capabilities. The humanoid Atlas robot, which has been overhauled with a sleeker design, can be seen at the beginning of the video walking around untethered before it opens the front door to Boston Dynamics' office and steps outside. The new-and-improved robot is "designed to operate outdoors and inside buildings," Boston Dynamics wrote in a description of the video posted on YouTube. Read More » 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. Read More » 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.
