US Secretary of State John Kerry on Friday urged signatories of an international ozone pact to back the phasing-out of hydrofluorocarbons (HFCs) -- toxic greenhouse gases thousands of times more potent than carbon dioxide. "Climate change is happening – and it is happening quicker than most of us ever anticipated," Kerry said. "Week after week, month after month, year after year, we continue to see new evidence, tangible evidence, of the danger climate change poses to our planet.
“There is no argument, on current evidence, for a safe level of drinking with respect to cancer,” Jennie Connor, the author and a professor of epidemiology at Otago University in New Zealand, wrote in the analysis, published Thursday in the scientific journal Addiction. Connor’s report found there is strong evidence that alcohol causes cancer of the liver, colon, rectum, esophagus, larynx, pharynx and female breast. “Alcohol consumption is one of the most important known risk factors for human cancer and potentially one of the most avoidable factors, but it is increasing worldwide,” the authors of that study wrote.
A 65-year-old Russian adventurer reached the Australian coast on Saturday and was within a few hours of setting a new record for flying solo nonstop around the world, an official said. Fedor Konyukhov's 56-meter (184-foot) -tall helium and hot-air balloon was descending as it crossed the southwest coast directly over the city of Perth at 95 kilometers (60 miles) per hour and at an altitude of less than 7,000 meters (23,000 feet), support crew member Steve Griffin said. When he drifts across 117 degrees longitude east of Perth, he will have shaved two days off the record of 13 days and eight hours set by American businessman Steve Fossett in 2002.
07/22/2016 01:35 pm 13:35:18 | Updated 1 hour ago The past few weeks have been full of several unfortunate violent events: the massacre in Orlando, the killing of black men by police officers, the sniper attack in Dallas, the Bastille Day attack in France, the violent coup attempt in Turkey and the shooting in Baton Rouge, Louisiana. While many of us may not have been directly affected by these events, we watched the news as it unfolded on broadcast and social media. Witnessing such violence on media can take a severe toll on us even when our near and dear ones are not directly affected. Surprisingly, what research is beginning to uncover is that impact on young children - especially young gifted
By Lila Hassan CAIRO (Reuters) - An aircraft powered by solar energy left Egypt on Sunday on the last leg of the first ever fuel-free flight around the globe. Solar Impulse 2, a spindly single-seat plane, took off from Cairo in darkness en route to Abu Dhabi, its final destination, with a flight expected to take between 48 and 72 hours. The plane, which began its journey in Abu Dhabi in March 2015, has been piloted in turns by Swiss aviators Andre Borschberg and Bertrand Piccard in a campaign to build support for clean energy technologies.
No matter how long it lasts, jet lag is never fun, and researchers still haven't found a "cure" for the bothersome side-effect. It turns out that our internal clocks are a bit laggy — they run a tad longer than 24 hours.
Around 10 million years ago, a population of African apes diverged down two paths. One lineage gave rise to gorillas. The other eventually split again, producing one branch that led to humans and another that forked into chimpanzees and bonobos. This is the story of our recent evolutionary past. It’s also the story of some of the microbes in our guts. We have tens of trillions of bacteria and other microbes in our guts—at least one for each of our own human cells. Some species within this microbiome are passers-by, which we pick up from our food and our environments. But others are much older companions. Andrew Moeller from the University of California, Berkeley, has found that there are a few
The idea that Star Trek has changed the world might sound as farfetched as some of the USS Enterprise’s spacefaring missions, but the truth is that the science fiction series has directly or indirectly impacted both our present and future. It seems like an absurd statement — when creator Gene Roddenberry was first kicking around the idea in 1964, he probably never imagined that Star Trek would still be around in 2016 with reboots in the pipeline. Here are seven ways that Star Trek changed the world. 1.
A detailed new map of the human brain's outer layer identifies nearly 100 brain areas that have not been previously reported, according to a new study. The new map may ultimately help brain surgeons plan operations. It will also help scientists better understand differences between the brains of typical people and the brains of people with disorders related to brain functioning, such as autism, schizophrenia and dementia, researchers who were not affiliated with the new study said. In the study, researchers identified a total of 180 areas of the cerebral cortex — the outermost layer of the brain — in each brain hemisphere, said lead study author Matthew Glasser, a neuroscience researcher at Washington University in Saint Louis.
The European Commission on Friday approved imports of Monsanto's Roundup Ready 2 Xtend genetically modified soybean variety, after months of delays that had derailed the U.S. seed giant's product launch this spring. Rivals Cargill Inc, Bunge Ltd and CHS Inc, which had also refused to accept the variety without EU import approval, could not be immediately reached for comment. The EU is the second largest importer of soybeans and its approval is not expected to have a major impact on merger talks by German suitor Bayer AG, whose sweetened $64-billion buyout offer of Monsanto was rejected last week, as it had been widely anticipated, analysts said on Friday.
Her computer, Karin Strauss says, contains her "digital attic" — a place where she stores that published math paper she wrote in high school, and computer science schoolwork from college. Strauss, who works at Microsoft Research in Redmond, Washington, is working to make that sci-fi fantasy a reality. Rather, they aim to help companies and institutions archive huge amounts of data for decades or centuries, at a time when the world is generating digital data faster than it can store it.
The Philippines is reviewing its "crazy" commitment to severely cut greenhouse-gas emissions in the Paris climate deal, new President Rodrigo Duterte has warned. The government of predecessor Benigno Aquino had pledged to the United Nations to cut the Asian country's emissions by 70 percent by 2030 from 2000 levels if it got support from developed nations to convert to clean technologies. "I have misgivings about this Paris (climate deal).... The problem is these industrialised countries have reached their destination," Duterte said in a series of speeches during a visit to the southern island of Mindanao on Friday.
Although it has been common knowledge that Da Vinci conducted the first systematic study of friction (which underpins the modern science of tribology, or the study of friction, lubrication, and wear), we didn't know how and when he came up with these ideas. Hutchings was able to put together a detailed chronology, pinpointing Da Vinci's "aha" moment to a single page of scribbles penned in red chalk in 1493. Almost a century later, Hutchings thought this page was worth a second look.
China has completed production of the world's largest amphibious aircraft after seven years of work, which it plans to use to perform marine rescue missions and fight forest fires, the Xinhua news agency reported. The AG600, which is about the size of a Boeing 737 and was developed by state aircraft maker Aviation Industry Corporation of China (AVIC), rolled off a production line in the southern city of Zhuhai on Saturday, Xinhua said quoting the firm. AVIC deputy general manager, Geng Rugang, said the plane was "the latest breakthrough in China's aviation industry." A plan for the development and production of the AG600 received government approval in 2009.
Stand in a field of wheat — amid the undulating stalks of grain, the blue dome of the sky overhead — and it’s hard not to be moved by the landscape, like you’ve stumbled into a patriotic song, which of course you have. When you’re the farmer, the stanza runs a little differently. You still have the beauty and the mountains, but the equation is also the very basic one of bread and water. And if that sounds more like a survivalist’s manual than the national anthem, it probably should. At Weiser Family Farms in Tehachapi, about 100 miles north of Los Angeles, Alex Weiser is harvesting his fields of Sonora and Red Fife wheat, as well as those of Abruzzi rye and French Black oats, as part of what
Guardians of the Galaxy: Vol 2 has been generating a lot of buzz during the lead-up to and including San Diego Comic Con 2016 where tomorrow it’ll have a panel during the Marvel Studios Hall H presentation. The sequel to the outer-space superhero ensemble won’t be hitting theaters till summer 2017, but that hasn’t stopped fans getting excited about what little we have seen so far. Directed by James Gunn, the followup to Guardians of the Galaxy features the original cast alongside some new faces from the comic books, and this year’s SDCC has already shown us a new portrait of Yondu along with a concept art poster featuring the new, and larger team roster. Now NASA is even getting in on the Guardians
A new study led by the Smithsonian Institution and the University of Copenhagen found that a species of ants in South America known as attini were cultivating fungi 55 to 60 million years ago, just after the age of the dinosaurs. By analyzing the genes of today's fungus-farming ants, the scientists pieced together the history of ant farmers and the fungi species they harvested. "Industrial-scale farming, comparable to that in humans, has evolved in only two non-human organisms, the fungus-growing ants and termites," says the study, published yesterday in the journal Nature Communications.
Yoldine Nicoleau stuffed a strawberry into a Ziploc bag and smashed it to a pulp. As about 20 other girls joined in, the science lab quickly filled with the sweet smell of fresh fruit and the sound of fists pounding on tables. This is what it takes to extract DNA from grocery store items. It’s also what getting girls interested in science looks, smells and sounds like. “This is fun for me,” said Nicoleau, a rising junior at Miami-Dade’s School for Advanced Studies. “I feel comfortable. I enjoy it. I’m around people who understand me.” For a week this summer, a group of young women from across Miami-Dade County got a hands-on introduction to working in STEM — Science, Technology, Engineering and
Currently, 21 percent of these emissions come from deforestation and land use changes that are a result of agriculture. The authors estimate that if land clearing for food production continues at its current pace, emissions from land use changes alone could increase by at least 30 percent in 2050.
A trove of ancient Roman treasure has been discovered on Spain's Costa Brava by a team of archaeology students. Two hundred silver denarii coins were found in an elaborate ceramic vase at the 2,500-year-old Empuries site. The ruins of Empuries stand were an ancient town overlooking the sea, on Catalonia's coast, used to stand. The city was founded around 575BC by Greek settlers from Phocaea and was later occupied by Roman forces. However, in the early Middle Ages, it was abandoned because its coastal position made it too vulnerable to attacks. The ancient site has been excavated since 1908 and has yielded a range of discoveries over the years, but as this treasure shows, it might still hide many
Individual honey bees aren’t very smart, yet honey bee hives, which may contain tens of thousands of individual bees, show remarkable intelligence. Scientists who study this type of swarm intelligence point out a key ingredient: no one is in charge. The hive functions just fine with no management, just countless interactions between individual bees with each following simple rules of thumb. A system like this is called self-organizing. Life itself is self-organizing. That’s how swarm intelligence works: simple creatures following simple rules, each one acting on local information. No bee sees the big picture. No bee tells any other bee what to do. No fearless leader is required or desired. In
TüBINGEN, Germany, July 22 (UPI) -- Despite its technological importance to early hunter-gatherers, archaeologists know relatively little about the production and use of rope and twine during the Paleolithic Era. Artifacts recently unearthed in Germany suggest some early humans used specialized ivory tools to make rope. Researchers from the University of Tübingen and the University of Liège recovered a neatly preserved piece of mammoth ivory with intricate carvings. Researchers determined the tool was made 40,000 years ago, around the time the first humans arrived in Europe. Analysis of the ivory suggests the carved notches weren't simply for decoration but were for the explicit purpose of weaving
Hyundai announced this year the start of Project Ioniq, its attempt at figuring out what the world of 2030 will be like. Of course the project would also use that information to determine how that world will affect the transportation industry. And it happens to share its name with the company's newest eco-friendly model. The first part of Project Ioniq is under way with the Ioniq Lab. This lab will be run by Dr. Soon Jong Lee, a professor at Seoul National University. Lee is also in charge of the Korea Future Design and Research Institute, and ten researchers and ten consultant experts will assist him on the project. Phase one has now yielded what Hyundai sees as 12 "megatrends" that will affect
