Scientists are working to create yeast that operates with custom-made DNA. They have long been able to make specific changes in an organism's DNA. Now, they're pushing into the more radical step of starting over, and building redesigned versions from scratch. Their work is part of a bold and controversial pursuit aimed at creating custom-made DNA codes to be inserted into living cells to change how they function, or even provide treatments for diseases. It could also someday help give scientists the profound and unsettling ability to create entirely new organisms. The genetic code is like a book written with an alphabet of only four letters: A, C, G, and T. Chemical building blocks that correspond
President Donald Trump said today (July 26) that transgender individuals could not serve in the military. "After consultation with my Generals and military experts, please be advised that the United States Government will not accept or allow … transgender individuals to serve in any capacity in the U.S. Military," Trump tweeted. "Our military must be focused on decisive and overwhelming … victory and cannot be burdened with the tremendous medical costs and disruption that transgender in the military would entail," he continued in another tweet.
NEW YORK (AP) — "Pharma Bro" Martin Shkreli has kept up his trademark trolling on social media during his securities fraud trial — calling the case "bogus" — but the jury won't hear him defend himself in court. Closing arguments are set for Thursday, with deliberations expected to begin as early as Friday. Although not part of the case, the price-gouging scandal has hung over the trial and burdened Shkreli with a likability deficit that made it even more of a longshot that he would testify.
Bormes-les-Mimosas (France) (AFP) - Local residents joined firefighters in southern France Wednesday to battle blazes that have forced over 10,000 people to flee and left chunks of coastal forest a blackened mess. In some places, locals used spades, rakes and even tree branches in a desperate bid to beat back the flames until the firefighters arrived. Forest fires were also raging in parts of central Portugal, where several villages were evacuated and roads closed down.
Girl Scouts from Daisies to teen Ambassadors may earn 23 new badges focused on science, technology, engineering and math. It’s the largest addition of new badges in a decade for Girl Scouts of the USA. The effort takes a progressive approach to STEM and also nudges girls to become citizen scientists using the great outdoors as their laboratory. Among the new badges are those that introduce kindergarten and first-graders to the world of robots and engineering. Scouts can learn basic programming and build prototypes to solve everyday problems. Older Scouts will have the chance to enhance those skills, learning more about artificial intelligence, algorithms and how to formally present their work.
Elon Musk – of SpaceX and Tesla Motors fame – recently proposed the “Hyperloop,” a high-speed floating train that’s accelerated by magnets and coasts between destinations. Described by Musk himself as “the fifth mode of transport,” it’s intended to provide fast and safe transit, largely self-powered with electricity generated by its own solar panels. Musk recently announced his company would build a test track in California.
Not since Concorde was removed from service in October 2003 has a commercial airliner flown at beyond the speed of sound. Famously, a plane breaking the sound barrier provokes a "sonic boom" - a cacophonous whip-crack which, if it erupts close enough to the ground, can cause windows to break and complaints to be issued. Contrary to perception - and in spite of the popular consensus that the plane was generally a success in its 27 years of active service - supersonic flight over the US is banned, and has been since 1973.
The weather has always been an unpredictable element of agriculture, but climate change is expected to make matters significantly worse. The Met Office, the U.K.'s national weather service, used a novel approach to determine the probability of severe water stress in three major corn-producing regions that are responsible for 40 percent of global production . Instead of relying on observed historical data—which the researchers found to seriously underestimate the impact of climate change—the new study used a model focusing on water stress. The authors noted the limitations of the study, including its reliance on a single climate model, and they advise researchers to utilize multiple models in the future.
On Monday August 21, a solar eclipse will cut across the entire United States. And wherever you are, you will be able to see it. Even though the “totality” — the area where the sun is completely blocked out by the moon — is only 70 miles wide, the whole country (even Alaska and Hawaii) will experience a partial eclipse. This is what you’ll see, and the time you’ll see it, in your zip code. We recommend punching in a few different ones to see how the eclipse experience will vary across the country. Salem, Oregon (97301), is going to see a total eclipse. Downtown Los Angeles (90012) will see 62 percent of the sun blocked at the peak. In Lake Charles, Louisiana (70601), it’ll be 71 percent. The
Google has taken its cameras where few cameras have gone before, capturing images aboard the International Space Station.It's a first for Street View Imagery. With the help of French astronaut and aerospace engineer Thomas Pesquet, who returned to earth
A morning visual check by museum staff revealed that Snooty was missing, and he was later discovered caught in a duct behind the tank he shared with three young manatees, Jeff Rodgers, the museum's provost and chief operating officer, said at a news briefing in Bradenton yesterday (July 23).
A man accused of accidentally sparking a massive Utah wildfire that forced some 1,500 people from their homes last month and cost about $34 million to fight was charged Tuesday. Iron County prosecutor Scott Garrett told The Associated Press that his office charged Robert Ray Lyman, 60, with two misdemeanors. Garrett declined further comment, but authorities have said the fire started when a man set a pile of weeds on fire and it raged out of control near a cabin in the ski town of Brian Head on June 17.
Ever since Environmental Protection Agency (EPA) administrator Scott Pruitt and other Trump administration officials raised the idea of putting climate science up for debate, it's been an open question as to where the participants who doubt mainstream
The growth of dark algae on the Greenland ice sheet may cause it melt “faster and faster”, scientists have warned. Warmer weather has caused algae to appear on the sheet’s surface, changing the very complexion of the country’s landscape. Unlike white ice, dark algae absorbs the sun’s heat, accelerating the melting process.
Girl Scouts from tiny Daisies to teen Ambassadors may earn 23 new badges focused on science, technology, engineering and math. The effort takes a progressive approach to STEM and also nudges girls to become citizen scientists using the great outdoors as their laboratory. Among the new badges are those that introduce kindergarten and first graders to the world of robots and engineering.
“The likelihood of a door being ripped open by a human being is very low,” said Dennis Tajer, a pilot who’s been working for American Airlines for 25 years. “The higher interior pressurization actually seals the door to the frame,” said Douglas Moss, a pilot for United Airlines for 20 years.
Researchers have records of messages sent to "the farmer," asking when he wanted "the king" to be killed, Schaefer said. One exception is a case from 1850 B.C. in which "the farmer" died and the criminal retained the crown. The fact that ancient people were willing to go through such a process reveals how much fear they had about eclipses. Today, fear has been replaced by excitement. People look forward to total solar eclipses for years and hope for good weather so they don't miss the spectacle. But when did fear transition to excitement, and why? "Fear is broken intellectually," Schaefer said. When day turns to night In fifth-century B.C. Greece, the philosopher Anaxagoras sought to understand
For decades, scientists have thought the moon was a dry, dusty place, but it may be time to re-write the astronomy books. New findings are upending decades of understanding about our closest neighbor in space; an analysis of satellite data suggests the moon's interior may actually be pretty wet, which could help make it easier to fly to the moon and back, or even stay there awhile, reports CBS News' Jan Crawford. Using a recent picture of the moon's surface, and measuring the reflecting light, researchers at Brown University were able to detect water molecules in the colored areas. Red and yellow indicates a high concentration. The researchers say there could be as much water there as what is
Lemons were the acai bowls of the ancient Romans — prized by the privileged because they were rare, and treasured for their healing powers. In fact, this coveted fruit, as well as the citron, were the only citrus fruits known in the ancient Mediterranean — it took centuries for other fruits, such as oranges, limes and pomelos to spread westward from their native Southeast Asia, a new study finds. However, the citrus fruits that followed in later years weren't as exclusive as lemons and citrons, said the study's lead researcher, Dafna Langgut, an archaeobotanist at Tel Aviv University in Israel.
It was once nothing more than a Kickstarter dream, but earlier this year, Anova cemented its success after being acquired for an impressive $250 million. On Tuesday, the appliance maker announced a partnership with Field Company, yet another Kickstarter success story, whose cast-iron skillet raised over $1.6 million last year. Thanks to this new collaboration, Anova will be offering an exclusive limited batch of the Field Skillet before it’s made available to the general public.
Red imported fire ants are regarded as pests throughout the Southern US, where they’ve thrived since they were inadvertently introduced from South America in the 1930s or ’40s. But at a Georgia Tech laboratory, the question at hand is not how to get rid of fire ants, but rather what we can learn from them. These ants build large structures with their bodies without a leader directing the colony. Those ant aggregations display some interesting material properties, which is why they’ve attracted the attention of mechanical engineers. Check out the video above to learn more, or watch on our YouTube channel.
Gov. Jerry Brown and his predecessor, Arnold Schwarzenegger, stood side by side Tuesday to cheer the extension of one of the most ambitious programs in the U.S. to reduce fossil fuel pollution, while condemning President Donald Trump's failure to see climate change as a deadly threat. Schwarzenegger, a Republican, joined Brown, a Democrat, for a sunny outdoor ceremony overlooking San Francisco where the governor signed legislation to extend a program limiting emissions of climate-changing carbons that both have urged the world to emulate. Within view of the city's skyscrapers on Treasure Island, a man-made low-lying island threatened by rising seas from climate change, the signing was full of open rebukes for President Donald Trump, who withdrew the United States from the global Paris accord to cut carbon emissions.
The one thing these two disciplines have in common is the night sky. Since then, advances in astronomy have helped the stars shed some of their mystery, leaving us with pretty little things that light up the night sky.
Elon Musk has slammed Facebook CEO Mark Zuckerberg’s “limited” understanding of artificial intelligence. Musk was responding to Twitter user Darren Cunningham, who shared an article with recent comments from Zuckerberg.
