Senate Democrats question offshore drilling work amid shutdown

Yahoo Science News feed latest items - Wed, 01/23/2019 - 14:41

U.S. Senate Democrats are questioning the legal basis of the Trump administration's move to continue work on its five-year offshore drilling plan during the partial federal government shutdown. In a letter sent on Tuesday to David Bernhardt, the Department of Interior's acting secretary, and Walter Cruickshank, acting director of the Bureau of Ocean Energy Management (BOEM), the senators asked them to address why the BOEM's contingency plan was updated in January to allow 40 employees to work on the offshore leasing program.

Maduro rival claims Venezuela presidency amid protests, U.S. support

Yahoo Science News feed latest items - Wed, 01/23/2019 - 14:30

U.S. President Donald Trump formally recognized Guaido shortly after his announcement and praised his plan to hold elections. At a rally that brought hundreds of thousands of Venezuelans into the east of Caracas, Guaido said Maduro had usurped power and promised to create a transitional government that would help the country escape its hyperinflationary economic collapse. Guaido's declaration takes Venezuela into uncharted territory, with the possibility of the opposition now running a parallel government recognized abroad as legitimate but without control over state functions.

Boeing's flying car lifts off in race to revolutionize urban travel

Yahoo Science News feed latest items - Wed, 01/23/2019 - 14:20

Boeing Co said its flying car prototype hovered briefly in the air during an inaugural test flight on Wednesday, a small but significant step as the world's largest planemaker bids to revolutionize urban transportation and parcel delivery services. Boeing is competing with arch-rival Airbus SE and numerous other firms to introduce small self-flying vehicles capable of vertical takeoff and landing. Boeing's 30-foot-long (9 meter) aircraft - part helicopter, part drone and part fixed-wing plane - lifted a few feet off the ground and made a soft landing after less than a minute of being airborne at an airport in Manassas, Virginia, Boeing said.

This is what a star looks like when it dies

Yahoo Science News feed latest items - Wed, 01/23/2019 - 12:44

Our Sun is one of the reasons we're all here today and we simply couldn't exist without it, but it won't be around forever. At some point far in the future our Sun will die, and when it does it'll probably look a lot like this image captured by the European Southern Observatory's Very Large Telescope. What you're seeing here is a nebula labeled ESO 577-24, and it's what's left of what was once a red giant star and, before that, a main sequence star in the prime of its life. Now, it's a white-hot ball of matter a fraction of its original size, and the colossal blast of gas surrounding it is the star's "last breath." "This planetary nebula is the remains of a dead giant star that has thrown off its outer layers, leaving behind a small, intensely hot dwarf star," ESO explains. "This diminished remnant will gradually cool and fade, living out its days as the mere ghost of a once-vast red giant star." When a star becomes a red giant it can wreak havoc on anything that happens to be orbiting it. The star balloons in size, swallowing up nearby planets as it grows in size before eventually collapsing in on itself in a colossal explosion. That big boom is what we're seeing in the image of ESO 577-24, but it won't stick around for all that long. After about 10,000 years, the glowing gasses will have spread thin and faded from view. This particular dying star is around 1,400 light years from Earth and you'd never be able to see it with the naked eye. ESO's Very Large Telescope began surveying the sky over two decades ago, and since then it has produced some truly stunning glimpses of objects in deep space.

U.S. recognizes opposition leader as Venezuela president, weighs oil sanctions

Yahoo Science News feed latest items - Wed, 01/23/2019 - 12:13

With street protests against Maduro underway across Venezuela, Trump said the United States recognized Juan Guaido, head of the opposition-controlled Congress, as the country's leader and called socialist President Nicolas Maduro's government "illegitimate." "I will continue to use the full weight of United States economic and diplomatic power to press for the restoration of Venezuelan democracy," Trump said in a statement, encouraging other governments in the Western Hemisphere to also recognize Guaido. U.S. Secretary of State Mike Pompeo, in a statement, called on Maduro to step aside and urged the country's military to support efforts to restore democracy. Venezuelan opposition sympathizers had been urging Guaido to assume the presidency since Maduro was inaugurated to a second term on Jan. 10 following a widely boycotted election last year that the United States and many other foreign governments described as fraudulent.

BBC's George Alagiah returns to the News at Six for first time after year off air for treatment

Yahoo Science News feed latest items - Wed, 01/23/2019 - 12:10

BBC News anchor George Alagiah returned to the air last night for the first time in more than a year, following a battle with cancer. Sporting a new beard, the 63-year-old fronted the News at Six programme after earlier revealing his illness was now in “a holding pattern”. He was first diagnosed with bowel cancer in 2014 and has since made intermittent returns to the broadcaster, where he has worked since 1989. Fellow presenter Sophie Raworth confirmed the comeback yesterday morning by posting a picture on Twitter of Alagiah smiling and suited in the newsroom. Back with a beard...1st time on air since December 2017. Join @BBCAlagiah on @BBCOne for tonight’s #BBCNewsSixpic.twitter.com/3TmuCdQjqE— sophieraworth (@sophieraworth) January 23, 2019 Her post prompted him to quip in response: “There goes my hope of slipping back into the studio unnoticed!” He added: “Thanks to all for good wishes. We’ve got the cancer in a holding pattern so it’s back to work with colleagues I respect and the viewers who make it worthwhile.” @sophieraworth there goes my hopes of slipping back into the studio unnoticed! Thanks to all for good wishes. We’ve got the cancer in a holding pattern so it’s back to work with colleagues I respect and the viewers who make it worthwhile. #BBCNewsSix— George Alagiah (@BBCAlagiah) January 23, 2019 Politicians and BBC personalities were among those to welcome news of Alagiah’s return, including Labour MP David Lammy, who hailed him as “one of the best in the business”. Alagiah was told that his stage four bowel cancer had returned just before Christmas 2017, leading him to take further time away from the screen to seek treatment. After the initial diagnosis in 2014, the disease spread to his liver and lymph nodes, but the presenter returned to work a year later after undergoing several rounds of chemotherapy and three major operations, one of which included the removal of most of his liver.

U.S. sanctions on Venezuela would reroute crude, leave refiners short

Yahoo Science News feed latest items - Wed, 01/23/2019 - 12:05

U.S. refineries that depend on Venezuela's heavy crude would have even more trouble securing supplies as Canadian and Mexican crudes are often not as discounted and are limited in availability. The United States is considering moves to cripple Venezuela's oil shipments, which account for nearly all of the country's exports, in response to the reelection of President Nicolas Maduro that was widely viewed as a sham. Washington has recognized opposition leader Juan Guaido as Venezuela's president as protests against Maduro erupt across the country.

Gum disease may be central to Alzheimer's development, say scientists

Yahoo Science News feed latest items - Wed, 01/23/2019 - 12:00

Gum disease may play a pivotal role in the development of Alzheimer’s disease, scientists believe, leading to hopes that good dental care or drugs could stave off or halt dementia. Researchers said they now had ‘solid evidence’ that the bacteria which causes periodontitis produces an enzyme which destroys neurons leading to memory loss. The bacteria Porphyromonas gingivalis ( P. gingivalis) is one of the chief causes of gum disease and tooth loss in humans, and has previously been associated with heart problems. In a series of experiments, an international team of researchers tested the brains of 53 people with Alzheimer’s and found the bacteria enzyme in 96 per cent. DNA evidence of the bacteria was also found in spinal fluid from seven out of 10 living patients diagnosed with Alzheimer's, and it was also present in the saliva of each one. In animal studies the bug was also found to spread from the mouths of mice to their brains, where the enzyme destroyed neurons. The researchers believe that the bacteria may be responsible for the tell-tale tangles of tau proteins seen in the brains of Alzheimer’s patients which contribute to the death of brain cells. Writing in the journal Science Advances, they said: “After entering the brain, we suggest that P. gingivalis may spread slowly over many years from neuron to neuron along anatomically connected pathways. “We propose that tau pathology seen in Alzheimer’s disease brains may be due to the spread of P. gingivalis.” Gum disease affects an estimated 45 per cent of the UK population, according to the British Dental Association (BDA), and nearly 10 per cent suffer from the more severe form of periodontitis. The scientists also tested drugs which blocked the enzyme produced by bacteria and found they were able to half brain degeneration in mice. One drug, given to mice in food, effectively treated P. gingivalis brain infections and prevented the loss of memory neurons. It also reduced inflammation and levels of beta-amyloid, a brain molecule strongly linked to Alzheimer's. The team has now developed a new drug, COR388, that better penetrates the central nervous system and could form the basis of a human Alzheimer's treatment. A large-scale clinical trial that will involve giving the drug to patients with mild to moderate Alzheimer's is planned for later this year. Dr Stephen Dominy, one of the study authors and co-founder of the US company Cortexyme, which developed COR388, said: “Infectious agents have been implicated in the development and progression of Alzheimer's disease before, but the evidence of causation hasn't been convincing. “Now, for the first time, we have solid evidence connecting the intracellular gram-negative pathogen Pg (P. gingivalis) and Alzheimer's pathogenisis, while also demonstrating the potential for a class of small molecule therapies to change the trajectory of the disease.” Dr David Reynolds, chief scientific officer at charity Alzheimer's Research UK, said that Alzheimer's was likely to have multiple causes, one of which may be gum disease bacteria. He added: “Maintaining good dental health is an important part of a healthy lifestyle, and while we don't yet fully know the extent to which it can affect our dementia risk, the presence of a single type of bacteria is extremely unlikely to be the only cause of the condition." BDA scientific adviser Professor Damien Walmsley said: “This study offers a welcome reminder that oral health can't remain an optional extra in our health service. “Everyone's life can be improved by regular appointments and good oral hygiene, reducing the bacterial load that's ever present in our mouths to a level that's unlikely to cause tooth decay, gum disease or tooth loss.” Dr James Pickett, Head of Research at Alzheimer’s Society, added: “Success of this new drug depends on whether the infection really does play an important role in Alzheimer’s disease – it’s important to pursue that as there hasn’t been a new drug for dementia in 15 years. “The upcoming clinical trial will be a crucial test to see if this can be a potential treatment for Alzheimer’s.”
