Last August, Elon Musk announced that Tesla was working on a bipedal humanoid robot that could perform boring and/or dangerous tasks for humans. His company has now unveiled two prototypes, one of which can already walk on its own.

Last year, engineers at Purdue University used their expertise in materials science to produce the world’s whitest paint, and have now made some tweaks to the recipe and produced a version that is thinner and lighter.

Space startup SpinLaunch's kinetic launch system will require payloads to endure 10,000 g and speeds of 5,000 mph (8,000 km/h) and in this regard, the company may have just passed its biggest test yet.

New modeling from the CDC estimates Omicron subvariants BQ.1 and BQ.1.1 now account for over 10% of all infections in the US. Scientists predict these rapidly spreading variants will drive a new wave of infections in the country over the coming months.

Ordinarily, we associate mouthguards with sports such as boxing and football. An experimental new one, however, could allow people who lack the use of their hands to control electronic devices – and it would do so by tracking their bite patterns.

Two new studies in the journal Cell have reported on unexpected ways pain-sensing neurons in the gut can serve as more than just sensory alarm systems. The research suggests these neurons also can directly protect the gut from inflammatory damage.

The rise of drug-resistant bacteria calls for new approaches to how doctors protect against bone infection after joint replacements, and a potent new form of bone cement is poised to take up the fight.

The tiny Pacific mole crab (Emerita analoga) has a unique talent, in that it can burrow straight down into the sand using its flexible legs. An experimental new robot copies that capability, and it could actually have some practical applications.

Scientists have developed a new method of providing information on 3D-printed foods, by printing a QR code within the food itself. Doing so doesn't affect the taste or outward appearance of the food, nor does it require the use of any labels.

Compelling new research has homed in on a genetic variant that seems to play a significant role in how well people generate an immune response to COVID-19 vaccines and their chances of experiencing a breakthrough infection in the year after vaccination.

Aeromine says its unique "motionless" rooftop wind generators deliver up to 50% more energy than a solar array of the same price, while taking up just 10% of the roof space and operating more or less silently. In independent tests, they seem legit.

Brain cancer is one of the most insidious forms of the disease, but a new wireless device could help improve survival times. When implanted between the skin and skull, the device uses infrared to heat up gold nanoparticles to kill cancer from within.
