WASHINGTON — NASA postponed a spacewalk outside the International Space Station by two astronauts just hours before it was scheduled to start after getting a warning that debris would pass close to the station.

In a brief statement issued early Nov. 30, NASA said a “debris notification” it received on the evening of Nov. 29 led the agency to postpone the spacewalk by astronauts Tom Marshburn and Kayla Barron, which had been scheduled to start at about 7:10 a.m. Eastern. The two had planned to replace an S-band antenna on the station’s truss that recently lost the ability to transmit data.

“Due to the lack of opportunity to properly assess the risk it could pose to the astronauts, teams have decided to delay the spacewalk until more information is available,” NASA said in the statement. The agency did not identify the debris in question or the times and distances of closest approach to the station.

According to reports, Samsung will increase the proportion of Exynos chips used in its own models in 2022 to reduce its dependence on Qualcomm chips. Samsung’s use of Exynos chips in its own models will increase by about 2–3 times next year. At the same time, Samsung has set a sales target of 300 million mobile phones next year.

Industry insiders pointed out that Samsung is vigorously supporting Exynos chips. On the one hand, it will increase the proportion of Exynos chips in its own models. On the other hand, it is open to partners. Recall that the company co-developed the Exynos 1,080 chip with Vivo which the latter used in the Vivo X60 series.

Stethoscopes are among doctors’ most important instruments, yet there have not been any essential improvements to the device since the 1960s. Now, researchers at Aalto University have developed a device that analyzes a broad range of bodily functions and offers physicians a probable diagnosis as well as suggestions for appropriate further examinations. The researchers believe that the new device could eventually replace the stethoscope and enable quicker and more precise diagnoses.

A startup called Vital Signs is taking the device to the market. The researchers are currently testing the device in a clinical pilot trial. The intention is to launch the product to the most important European markets by the end of 2023.

“We have a well-functioning prototype, and the development path is clear,” says Alexis Kouros, the doctor leading the research team at Aalto.

Markets plunged on Friday, hope of taming the coronavirus dimmed and a new term entered the pandemic lexicon: Omicron.

The Covid-19 variant that emerged in South Africa was named after the 15th letter of the Greek alphabet.

The naming system, announced by the World Health Organization in May, makes public communication about variants easier and less confusing, the agency and experts said.
