    Kerry urges phasing-out of toxic greenhouse gases

    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.

    Russian balloonist circling globe crosses Australian coast

    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.

    Alcohol's cancer risks outweigh any health benefits, study shows

    “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.

    New brain map unearths 97 new areas

    A new map of the brain based on scans of 420 people has defined 97 new functional parts of the cortex – the wrinkled grey outer shell – more than doubling previous tallies. The atlas and software, produced by researchers in the US and the Netherlands, combines different imaging and measurement techniques to assign each cortex area a "fingerprint" based on architecture, cell type and function. The work was published in Nature. Mapping the human brain is a centuries-old exercise. The problem is everyone's brain is unique. Until recently, the best scientists could do was assign brain regions by, for instance, cell type. They dissected brains were examined under a microscope and saw different areas

    The Most Impossible Technology From 'Star Trek'

    Fifty years ago, a new vision of humanity’s future first graced the world’s consciousness: the vision of Star Trek. The brainchild of creator Gene Roddenberry , it ran contrary to the dominant ethos of its time of a world filled with the pollution and destruction of humans, overrun with selfish, unethical behavior, war, strife and conflict. Instead of a dystopian future where humanity brought about our own destruction, this was a future where technology existed to further the peaceful goals and ideals common to all humans. This was a future where the dream of the United Nations was extended to not just all of Earth, but to a myriad of planets beyond our Solar System: a United Federation of Planets.

    Plants have a microbiome just like humans — and it could transform how our food is produced

    Over the past several years, scientists have realized that the human microbiome — the catch-all term for the micro-organisms living inside us and on our skin — plays a key role in maintaining health. Our microbes, it turns out, can impact everything from weight to whether a person gets diabetes or cancer.  A startup called Indigo is now offering microbe-enhanced crops to farmers. First up: cotton coated with a microbe that can improve yield in drought conditions. Indigo started selling to customers during the spring as they were planting cotton seed; the product is now planted on over 50,000 acres in Texas and four surrounding states. In earlier trials, coated seeds improved yields by 10% compared

    EU approves Monsanto, Bayer genetically modified soybeans

    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.

    Are gifted kids more sensitive to screen violence?

    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

    Removing Wylfa nuclear plant's radioactive fuel 'priority'

    The push to recover used radioactive fuel from the last nuclear power station of its kind is under way. Wylfa nuclear plant's last reactor was turned off after 44 years at an outage ceremony on Anglesey in December. Workers have spent the past six months putting decommissioning plans into action, including a new safety regime. Removing 800 tonnes of spent Magnox fuel will now be the "dominant" focus over the next three years, officials have said. "Once we are fuel free, over 99% of all the radioactivity on the site will have left," said Gordon Malcolm, deputy site director at Wylfa. "Then the whole site moves on to the next phase of work, preparations for care and maintenance... which will last

    Brazil scientists find Zika traces in Culex mosquitoes in wild

    Brazilian researchers on Thursday said they found signs of the Zika virus in a common mosquito that is a separate species from the insect known to be the primary means of transmission. They warned, however, that further tests are needed to determine whether the species, known as Culex quinquefasciatus, is in fact responsible for transmitting the virus to humans and, if so, to what extent. The scientists, from a leading Brazilian research institute known as the Oswaldo Cruz Foundation, discovered the Zika traces in Culex mosquitoes captured in and around the northeastern Brazilian city of Recife, capital of the state that was hit hardest by the Zika outbreak since last year. In March, the same

    US land capacity for feeding people could expand with dietary changes

    A new "food-print" model that measures the per-person land requirements of different diets suggests that, with dietary changes, the U.S. could feed significantly more people from existing agricultural land. Using ten different scenarios ranging from the average American diet to a purely vegan one, a team led by scientists from the Friedman School of Nutrition Science and Policy at Tufts University estimated that agricultural land in the contiguous U.S. could have the capacity to feed up to 800 million people—twice what can be supported based on current average diets. The researchers found that a vegetarian diet that includes dairy products could feed the most people from the area of land available.

    LUX: World's most sensitive detector finds no dark matter. What's next?

    The findings, presented at the Identification of Dark Matter conference in Sheffield, England, were not unexpected — though they do highlight the challenge of finding the elusive stuff known as dark matter. “I couldn’t say with a straight face that I was expecting to find dark matter with this particular data set,” said Simon Fiorucci, an experimental physicist at Lawrence Berkeley National Laboratory and science coordination manager for LUX. Dark matter can’t be seen, heard or felt – but scientists know something must be there because they watch how its enormous mass turbocharges the spin of galaxies. Everything we can detect in the universe, from Earth to the stars, black holes and distant galaxies – all of it makes up less than 5% of the mass and energy in the universe.

    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.

    The world's first graphene car is unveiled in Manchester

    The world's first car made with graphene in its bodywork has been unveiled in Manchester. The vehicle, with graphene in its panels, was made by Briggs Automotive Company in Speke, Liverpool. The BAC Mono spearheads an exhibition to highlight the future technology of graphene, which is 200 times stronger than steel. It was developed by scientists at the University of Manchester in 2004 who won the Nobel Prize for it. Graphene is made of sheets of carbon just one atom thick. The BAC Mono has been road-tested and is being displayed at the National Graphene Institute in Manchester as part of the Science in the City festival from July 22-29.

    Chinese team to pioneer first human CRISPR trial

    (Medical Xpress)—A team of researchers at Sichuan University's West China Hospital has announced plans to begin a clinical trial where cells modified using the CRISPR gene editing technique will be used on human beings for the very first time. They plan to edit genes in such a way as to turn off a gene that encodes for a protein that has been shown by prior research to slow an immune response and by so doing treat patients with lung cancer. The CRISPR gene editing technique has been in the news a lot of late as scientists creep ever closer to using it as a means to treat diseases or to change the very nature of biological beings. China has been a leader in promoting such research on human beings—they

    Philippines reviewing 'crazy' climate pledges: Duterte

    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.

    Ants Started Farming Millions of Years Before Humans Did

    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
