Trump cancels Poland visit as hurricane heads for Florida

US President Donald Trump on Thursday cancelled a trip to Poland as Hurricane Dorian bore down on Florida, where it could make landfall as a dangerous Category 4 storm. Trump, who had been scheduled to attend World War II anniversary commemorations in Poland this weekend, said he would focus instead on preparations for the approaching hurricane. Vice President Mike Pence would go to Poland in...

Trump declares new Space Command key to American defense

Space Force, which has become a reliable applause line for Trump at his campaign rallies, has yet to win final approval by Congress. The role of the new Space Command is to conduct operations such as enabling satellite-based navigation and communications for troops and commanders in the field and providing warning of missile launches...

Billionaires Jack Ma and Elon Musk debate good, evil and AI at conference in China

In the debate over artificial intelligence, whose side is Elon Musk on? Musk, who's in charge of SpaceX, Tesla and the Neuralink brain interface venture, sized up the odds with AliBaba founder Jack Ma today during a widely watched one-on-one session at the World Artificial Intelligence Conference in Shanghai. The way Musk sees it, the prospects aren't great for humans if future AI agents...

Atmospheric battle will determine where Dorian hits Florida

It's a battle of mammoth meteorological forces, and at stake is where Hurricane Dorian strikes the United States. Four days before the system is expected to come ashore, Dorian could hit practically anywhere in Florida because the weather forces that will determine its path have not yet had their showdown, meteorologists said. As of Thursday, the National Hurricane Center had practically all of...

US rolls back regulations on industrial methane leaks

The US Environmental Protection Agency announced Thursday plans to roll back regulations that limit leaks of potent greenhouse gas methane from pipelines and wells, even as some industry players opposed the move. It is the latest in President Donald Trump's long battle against environmental protection rules, coming weeks after his administration made fundamental changes to a widely popular...

Venice Film Review: Brad Pitt in ‘Ad Astra’

In the opening sequence of "Ad Astra," Roy McBride (Brad Pitt), a veteran U.S. astronaut, is doing what he does at the top of a space antenna, an elaborate piece of technological scaffolding so tall that it juts right up from the earth into the outer void. (It’s enough to make that famous 1932 photograph...

Concerns arise over Hawaii prosecutor son's job

The man responsible for prosecuting the mostly Native Hawaiian elders arrested for protesting construction of a giant telescope said there is no conflict of interest, even though his son works for one of the embattled project's partners. Hawaii County Prosecuting Attorney Mitch Roth's 22-year-old son Aaron works at NASA's federally funded Jet Propulsion Laboratory, which is managed by the...

No single 'gay gene,' according to largest ever DNA analysis

Like size or intelligence, sexual attraction isn't defined by one gene alone, but is instead the result of the complex interplay between multiple regions of the genome and hard to pin environmental factors. Its authors hope to bury the notion, popularized in the 1990s, of the existence of an all powerful "gay gene" that determines sexuality in the way eye color is defined. "We... found that it's...

Idaho artefacts show human presence in Americas 16,600 years ago

Artefacts including stone tools and animal bone fragments found in Idaho dating back about 16,600 years represent what may be the oldest evidence of humans in the Americas and offer insight into the routes people took as they spread into the New World. Scientists on Thursday said they used a technique called radiocarbon dating to determine the age of artefacts unearthed at an archaeological site...

New genetic links to same-sex sexuality found in huge study

The largest study of its kind found new evidence that genes contribute to same-sex sexual behavior, but it echoes research that says there are no specific genes that make people gay. The genome-wide research on DNA from nearly half a million U.S. and U.K. adults identified five genetic variants not previously linked with gay or lesbian sexuality. The researchers said thousands more genetic...

Climate crisis: Trump to roll back Obama-era pollution regulations for oil and gas drilling designed to reduce methane emissions

The Trump administration plans to revoke Obama-era regulations designed to prevent hazardous methane leaks from oil and gas drilling operations, in a move which has even surprised those in fossil fuel industries.The head of the Environmental Protection Agency, Andrew Wheeler said the proposed rule change was to follow Donald Trump’s directions to remove “unnecessary and duplicative regulatory...

No 'gay gene', but study finds genetic links to sexual behaviour

A large scientific study into the biological basis of sexual behaviour has confirmed there is no single "gay gene" but that a complex mix of genetics and environment affects whether a person has same-sex sexual partners. The research, which analysed data on DNA and sexual experiences from almost half a million people, found there are thousands of genetic variants linked to same-sex sexual...

Idaho artifacts suggest Pacific entry for first Americans

Scientists say they've found artifacts in Idaho that indicate people were living there around 16,000 years ago, providing new evidence that the first Americans entered their new home by following the Pacific coast. The discovery also points to Japan as a possible origin or influence for the migration, said study leader Loren Davis of Oregon State...

Sanders brings climate discussion to South Carolina coast

The gathering is being held in Myrtle Beach, a focal point of South Carolina's $20 billion tourism industry. It comes on the heels of the Vermont senator's release last week of a $16.3 trillion climate change plan that calls for the United States to move to renewable energy across the economy by 2050 and declare climate change a national...

Major Companies Pledge to Shut Down for Global Climate Strike

Four of the most socially-conscious companies around will shut down on September 20th, and are encouraging their employees to take part in the Global Climate Strike. Green Day Ben & Jerry's, Lush Cosmetics, Patagonia, and Seventh Generation have all pledged support for the strike, which will take place as part of a week of action before the UN Climate Summit. The Global Climate Strike will see...

‘They’re so inspiring’: Jeff Bezos touts Blue Origin’s space postcard campaign for kids

When Amazon CEO Jeff Bezos unveiled a mockup of Blue Origin's Blue Moon lunar lander in May, he also unveiled a more down-to-earth enterprise: the Club for the Future, a nonprofit effort aimed at promoting science education through fun space-oriented projects. Its first project? A campaign to solicit postcards that would be flown into space aboard Blue Origin's suborbital New Shepard...

Human-like neural activity detected in lab grown mini brains

Scientists reported Thursday they had picked up human-like electrical activity in lab-grown brains for the first time, paving the way to model neurological conditions and answer fundamental questions on how our gray matter develops. "If you had asked me five years ago 'Would you think that a brain organoid would ever have a sophisticated network able to generate a brain oscillation?' I would say...
