One trick is to

Ferroelectrics are pretty remarkable materials At the heart of computing are tiny crystals that transmit and store digital information’s ones and zeroes. Today these are hard and brittle materials. But cheap, flexible, nontoxic organic molecules may play a role in the future of hardware. A team led by the University of Washington in Seattle and

In some cases, radio frequency signals may be more useful for caregivers than cameras or other data-collection methods. We live in a world of wireless signals flowing around us and bouncing off our bodies. MIT researchers are now leveraging those signal reflections to provide scientists and caregivers with valuable insights into people’s behavior and health.

In many parts of the world, shark attacks are a very real possibility for anyone entering the ocean. While suspended nets do help keep the toothsome fish separated from swimmers, they’re far from from 100 percent reliable, plus sharks (along with other marine animals) regularly get caught in them and perish – as sharks are

Space vehicles like SpaceX’s Falcon 9 are designed to be reusable. But this means that, like Olympic gymnasts hoping for a gold medal, they have to stick their landings. Landing is stressful on a rocket’s legs because they must handle the force from the impact with the landing pad. One way to combat this is to build

Politicians and companies — including telcos, tech companies, service providers and more — are all quite worried We’ve been covering how the UN’s International Telecommunications Union (ITU) has been moving forward with its plans next month to consider a number of proposals to takeover aspects of internet regulation and governance. There are, of course, a number of

A new circuit layout makes it robust against cuts, damage, and removed areas. If a pair of long pants is too long, it is cut to length. A board that does not fit into a bookcase is sawed to the right length. People often customize the size and shape of materials like textiles and wood

The two companies essentially committed suicide. The shutdown of two small e-mail providers on Thursday illustrates why it is so hard for Internet companies to challenge secret government surveillance: to protect their customers’ data from federal authorities, the two companies essentially committed suicide. Lavabit, a Texas-based service that was reportedly used by Edward J. Snowden,

Pioneering technology makes OPEC countries prime regions to produce synthetic fuels. This could be a key asset in phasing out fossil fuels after the Paris Agreement, while also keeping some of the existing oil industry value chain intact The Organization of the Petroleum Exporting Countries (OPEC) holds its 172nd meeting in Vienna on Thursday, May
