Scientists in China claim to have built a hypersonic jet engine—called “sodramjet”—that can fly at 16 times the speed of sound. This means that an aircraft kitted out with such engines could fly anywhere in the world in two hours, according to the scientists. The test flight of a prototype was carried out in a wind tunnel in Beijing, China, and displayed excellent thrust, fuel efficiency, and operational stability. Led by Professor Zonglin Jiang of the Chinese Academy of Sciences’ Institute of Mechanics, the team’s findings were published in Chinese Journal of Aeronautics on Saturday.

Scientists in China have tested a prototype sodramjet engine in a hypersonic wind tunnel at nine times the speed of sound. Check it out here!

Federal officials are disappointed to find that the monoclonal antibody drugs they’ve shipped across the country aren’t being used rapidly.

These drugs are designed to prevent people recently diagnosed with COVID-19 from ending up in the hospital. But hospitals are finding it cumbersome to use these medicines, which must be given by IV infusion. And some patients and doctors are lukewarm about drugs that have an uncertain benefit.

Doctors hope that as word gets out, more people will end up trying these drugs. They are provided to health systems free by the federal government, but it costs money to administer the medication. At first, Medicare set a price that would require many patients to pay a $60 copay, but the Centers for Medicare and Medicaid Services later found a way to waive that fee.

Monoclonal antibodies to prevent severe COVID-19 aren’t being used as widely as expected. Medical staff shortages and patient transportation problems are two of the reasons.

When it comes to the semiconductor industry, silicon has reigned as king in the electronics field, but it is coming to the end of its physical limits.

To more effectively power the , locomotives and even , Lawrence Livermore National Laboratory (LLNL) scientists are turning to diamond as an ultra-wide bandgap semiconductor.

Diamond has been shown to have superior carrier mobility, break down electric field and thermal conductivity, the most important properties to power . It became especially desirable after the development of a chemical vapor deposition (CVD) process for growth of high-quality single crystals.

There they go again. Just a few months ago the US Department of Energy tapped a startup called Group14 Technologies for a multi-million dollar R&D grant to usher in a new generation of high performance EV batteries, and now here comes Group14 with another $17 million in series B funding spearheaded by the South Korean battery expert SK Materials. If you guessed that means scaling up production for the mass market, you’re right on the money. The bigger question is why the Energy Department is determined to support the US electric vehicle industry, considering that White House policy has been aimed at supporting the US oil industry. Any guesses?

Even Apple wants to get into the automobile business it seems.

(Reuters) — Apple Inc is moving forward with self-driving car technology and is targeting 2024 to produce a passenger vehicle that could include its own breakthrough battery technology, people familiar with the matter told Reuters.

The iPhone maker’s automotive efforts, known as Project Titan, have proceeded unevenly since 2014 when it first started to design its own vehicle from scratch. At one point, Apple drew back the effort to focus on software and reassessed its goals. Doug Field, an Apple veteran who had worked at Tesla Inc, returned to oversee the project in 2018 and laid off 190 people from the team in 2019.

Since then, Apple has progressed enough that it now aims to build a vehicle for consumers, two people familiar with the effort said, asking not to be named because Apple’s plans are not public. Apple’s goal of building a personal vehicle for the mass market contrasts with rivals such as Alphabet Inc’s Waymo, which has built robo-taxis to carry passengers for a driverless ride-hailing service.
