Fear that uproar over gene-edited babies could block science
Scientists working on the frontiers of medicine fear the uproar over the reported births of gene-edited babies in China could jeopardize promising research into how to alter heredity to fend off a variety of disorders. Researchers are rapidly learning how to edit DNA to fight such conditions as Huntington's, Tay-Sachs and hereditary heart disease, conducting legally permissible experiments in lab animals and petri dishes without taking the ultimate step of actually creating babies. Now they worry about a backlash against their work, too.
NASA takes a tangible step back toward the Moon with commercial program
NASA announced Thursday that it has partnered with nine companies to enable the delivery of small scientific payloads to the lunar surface. No money was exchanged up front, but the space agency said these companies would now be eligible to "bid" for contracts to deliver select experiments to the Moon.
Scientists Model Costs of Geoengineering Effort to Dim the Sun
Geoengineering -- the deliberate effort to manipulate the Earth’s climate in an attempt to offset, delay, or slow global warming -- has slowly transformed from a pie-in-the-sky idea to a serious concept that may well be attempted one day. A wide variety of schemes have been proposed for how we might cool the Earth, but many of these would require the development of technologies far beyond our current capability.
Einstein's theory of general relativity just survived a massive crash in outer space
Gravity is big and weird and difficult to study. It moves through space as a wave, sort of like how light does. But these waves are subtle and difficult to detect. They occur in measurable amounts only after massive events, like the collision of black holes.
Stop China's Infiltration of US Railroads
A myriad of problems has led to a "surprising level of foreign dependence on competitor nations," according to the White House’s long-awaited report on the severe challenges facing our manufacturing and defense industrial base. A look at one field -- manufacturing the railroad cars that carry America’s commuters and freight -- reveals growing dangers that demand urgent action.
China's Air Force Wants to Make Sure It Can Beat America in a War
The Chinese air force aims not just to compete with the U.S. Air Force, but to defeat it. All in pursuit of a uniquely Chinese strategy. To do so, Beijing's air arm buys technology where it can, steals or copies or it where it must and innovates new tech where there's nothing available to buy or steal.
Could better technology in your car be making you a worse driver?
Better technology in your vehicle could be making you into a worse driver. Some people are relying too much on those fancy new bells and whistles."Technology supports us as humans, it doesn't replace us," says Martha Meade, the government affairs and public relations manager for AAA Mid-Atlantic.
President Moves Forward With Plans to Tighten US High-Tech Exports
The Trump administration has received backing from Congress in taking a harder line over protecting critical U.S. technology from foreign threats. In August, President Donald Trump signed a law to strengthen a panel that reviews investments from abroad for national security risks, which was widely viewed as a way to curtail Chinese investment in the U.S.
Here's What’s Next for NASA's InSight Mars Lander
NASA’s InSight mission has successfully landed on the red planet, making it the first Mars landing for the agency in six years. With the solar panels deployed, it’s time for the probe to start doing some science. Well, it’s going to do some science. InSight has to do several months of prep work before most of its instruments will be ready to relay data back to Earth.
