Chipmakers often place orders with contract manufacturers instead of fabricating chips in-house. It takes time to manufacture semiconductors while reconfiguring lines to accommodate varying specifications, making it difficult to turn out different chips at the same time.

TOKYO — The auto industry is facing a severe lack of semiconductors amid rising use of the chips in other products, like smartphones and communication base stations.

This has forced Germany’s Volkswagen as well as Japanese makers like Honda and Nissan to reduce production.

Sierra Nevada, the spaceship’s maker, is also building the LIFE space habitat.

Delays, many related to COVID, have pushed the first flight of the Dream Chaser space plane to 2022.

China has hinted before that it would like to send missions to the outer planets. Chinese scientists, working with European collaborators, are now solidifying plans for two distinct Jupiter mission concepts, one of which will likely move forward. Both seek to unravel mysteries behind the planet’s origins and workings using a main spacecraft and one or more smaller vehicles.

The competing missions are called the Jupiter Callisto Orbiter and the Jupiter System Observer, or JCO and JSO, respectively. Both would launch in 2029 and arrive in 2035 after one Venus flyby and two Earth flybys. JCO and JSO would study the size, mass, and composition of Jupiter’s irregular satellites—those captured by Jupiter rather than formed in orbit, and often in distant, elliptical and even retrograde orbits—complementing science conducted by NASA’s Europa Clipper and Lucy missions, as well as the European Space Agency’s JUICE mission.

Both JCO and JSO would possibly include CubeSats with particle and field detector payloads to perform the first multi-point study of Jupiter’s magnetic field.

What is dark energy? More is unknown than is known — we know how much there is, and we know some of its properties; other than that, dark energy is a mystery — but an important one. Roughly 70% of the Universe is made of dark energy. Dark matter makes up about 25%. The rest — everything on Earth, everything ever observed with all of our instruments, all normal matter adds up to less than 5% of the Universe. Then again, maybe it shouldn’t be called “normal” matter since it is a small fraction of the Universe!

Researchers have found a simple way to eliminate almost all sequencing errors produced by a widely used portable DNA sequencer, potentially enabling scientists working outside the lab to study and track microorganisms like the SARS-CoV-2 virus more efficiently.

Using special molecular tags, the team was able to reduce the five-to-15 percent error rate of Oxford Nanopore Technologies’ MinION device to less than 0.005 percent—even when sequencing many long stretches of DNA at a time.

“The MinION has revolutionized the field of genomics by freeing DNA sequencing from the confines of large laboratories,” says Ryan Ziels, an assistant professor of civil engineering at the University of British Columbia and the co-lead author of the study, which was published this week in Nature Methods. “But until now, researchers haven’t been able to rely on the device in many settings because of its fairly high out-of-the-box error rate.”

Invasive round goby fish have impacted fisheries in the Great Lakes and the Finger Lakes by competing with native species and eating the eggs of some species of game fish.

But the camouflaged bottom dwellers can be difficult to find and collect—especially when they first enter a new body of water and their numbers are low and they might be easier to remove.

In a proof-of-principle study, Cornell researchers describe a new technique in which they analyzed environmental DNA—or eDNA—from water samples in Cayuga Lake to gather nuanced information about the presence of these invasive fish.

February 18 — We revisit the red planet with a new rover.

(MS) has been announced by a collaboration including BioNTech, with a study in mice showing great promise for improving symptoms and stopping disease progression.
