Launcher says one-piece manufacture lowers the cost of its part, compared with those printed in pieces and joined. To do this, the Brooklyn-based startup teamed with 3D printer companies to build a space large enough for its entire copper-alloy part, which itself is a huge investment.
Process is initially intended to save lives on Earth, rather than to send astronauts on long haul flights.
The fast-moving development of brain-machine interfaces got a boost when Elon Musk announced the work for Neuralink, his new company devoted to implantable devices to enhance cognition and better marry our brains with super-computing. His competitor, fellow tech entrepreneur Bryan Johnson of Kernel, weighs in on why he thinks advancing cognition can solve all the other problems in the world. But tech ethicist Tristan Harris says not so fast — we haven’t properly accounted for what existing tech has already done to us. Think things through with this brainy episode of Future You with Elise Hu.

Data from ESA’s Cluster mission has provided a recording of the eerie “song” that Earth sings when it is hit by a solar storm.
The song comes from waves that are generated in the Earth’s magnetic field by the collision of the storm. The storm itself is the eruption of electrically charged particles from the sun’s atmosphere.
A team led by Lucile Turc, a former ESA research fellow who is now based at the University of Helsinki, Finland, made the discovery after analyzing data from the Cluster Science Archive. The archive provides access to all data obtained during Cluster’s ongoing mission over almost two decades.
Synthetic protocells can be made to move toward and away from chemical signals, an important step for the development of new drug-delivery systems that could target specific locations in the body. By coating the surface of the protocells with enzymes—proteins that catalyze chemical reactions—a team of researchers at Penn State was able to control the direction of the protocell’s movement in a chemical gradient in a microfluidic device. A paper describing the research appears November 18, 2019 in the journal Nature Nanotechnology.
“The futuristic vision is to have drugs delivered by tiny ‘bots’ that can transport the drug to the specific location where it is needed,” said Ayusman Sen, the Verne M. Willaman Professor of Chemistry at Penn State and the leader of the research team. “Currently, if you take an antibiotic for an infection in your leg, it diffuses throughout your entire body. So, you have to take a higher dose in order to get enough of the antibiotic to your leg where it is needed. If we can control the directional movement of a drug-delivery system, we not only reduce the amount of the drug required but also can increase its speed of delivery.”
One way to address controlling direction is for the drug-delivery system to recognize and move towards specific chemical signals emanating from the infection site, a phenomenon called chemotaxis. Many organisms use chemotaxis as a survival strategy, to find food or escape toxins. Previous work had shown that enzymes undergo chemotactic movement because the reactions they catalyze produce energy that can be harnessed. However, most of that work had focused on positive chemotaxis, movement towards a chemical. Until now, little work had been done looking at negative chemotaxis. “Tunable” chemotaxis—the ability to control movement direction, towards and away from different chemical signals—had never been demonstrated.
At the start of this decade, the federal government called out consumer DNA testing as a burgeoning scam industry. Little did we know how it would explode in popularity.
In 2010, the U.S. Government Accountability Office (GAO) published an investigative report that bashed consumer DNA test companies for misleading the public. It accused them of deceptively claiming their products could predict the odds of developing more than a dozen medical conditions; some even went as far to offer equally dubious dietary supplements. The report had followed a similar lambasting of the industry by the GAO in 2006.
Google Earth launched creation tools that allow users to produce personalized narrative stories with custom maps and virtual tours.
The movie, which was set in November 2019, got a lot right about Los Angeles and the future–even the things it got wrong.
