Boeing 737 sized aircraft can “ski” on water.

China is set to test the latest prototype of its amphibious aircraft, the AG600, that will increase its maritime coverage to the entire South China Sea. The previous iterations of the aircraft have conducted separate trials on the land and sea in 2017 and 2020 respectively, South China Morning Post (SCMP) reported.

The South China Sea has become a contentious issue after China has claimed sovereignty over the region. Apart from untapped reserves of oil and natural gas, the region is also home to a third of the world’s maritime trade routes and fisheries that could impact the food security of millions in the region. The U.S. and its allies are keen on protecting the rights of other island nations even as China flexes its muscle in the region. sovereignty over the South China Sea, China needs to strengthen its maritime reach in the region and the AG600 will give it just that.

Half-Life: Alyx (2020) has been in the wild for a little under two years now, and modders have been busy using it to make cool stuff—just like they did with the original Half-Life (1998). Enter ‘Gunman Contracts’, a multi-chapter mod that scores some serious style points while smartly leveraging Valve’s Source 2 for some John Wick-style action.

Gunman Contracts is set of free mods for Half-Life: Alyx created by Germany-based graphics designer ‘ANB_Seth’.

There’s already two individual chapters available on the Steam, ‘Chapter 1 – The Extraction’, which came out last September, and now ‘Chapter 2 – Art of War’, which released late last month.

A comprehensive investigation by KAUST researchers sets the record straight on the formation of hydrogen peroxide in micrometer-sized water droplets, or microdroplets, and shows that ozone is the key to this transformation1,2.

The is a crucial site for numerous natural, domestic and such as ocean-atmosphere exchange, cloud and dew formation, aerated beverages and bioreactors. Yet, probing chemical transformations at the air– interface is challenging due to the lack of surface-specific techniques or computational models.

Recent research revealed that water spontaneously transforms into 30–110 micromolar hydrogen peroxide (H2O2) in microdroplets, obtained by condensing vapor or spraying water using pressurized nitrogen gas. The textbook understanding of water is thus challenged by how the mild temperature and pressure conditions, together with the absence of catalysts, co-solvents and significant applied energy, could break covalent O–H bonds. It was hypothesized that this unusual phenomenon resulted from an ultrahigh electric field at the air-water interface that assists OH radical formation, but no direct evidence has been reported.

The ExplOrigins early career group invites you to join the 2022 Exploration and Origins Colloquium on February 17th–18th, 2022! The live broadcast portion of this colloquium will begin at 10am ET on February 18th.

We are thrilled to have Dr. Amy Mainzer as our plenary speaker. Dr. Mainzer is a professor of planetary science at the University of Arizona, principal investigator of NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission, and lead of NASA’s Near-Earth Object (NEO) Surveyor mission. She also has achieved excellence in science communication, serving as the science curriculum consultant, on-camera host, and executive producer of the PBS Kids series Ready Jet Go! and as the science consultant for the Netflix movie Don’t Look Up.

Our program also highlights current astrobiology, origins, and space science projects presented by a cast of early career researchers from the Atlanta area.

Tesla Inc. Chief Executive Elon Musk donated more than 5 million Tesla shares in November, days after the U.N. World Food Program outlined a plan to potentially use a $6 billion donation from the world’s richest man.

A filing with the Securities and Exchange Commission made public Monday showed the donation, but not the recipient. The Tesla TSLA, +4.48% shares were transferred in batches between Nov. 19 and Nov. 29, as Musk was also selling Tesla stock in preparation for a large tax bill.

Tesla CEO Elon Musk donated over 5 million TSLA shares to an undisclosed charity, according to a SEC Form 5 filed on Monday, February 14, 2022.

The filing reveals that Elon Musk donated approximately 5,044,000 TSLA shares worth about $4.42 billion, considering that Tesla stock is priced at $875.76 as of this writing. Based on the SEC filing, Elon Musk started donating the stocks on November 19, 2021, a time when over 5 million TSLA shares were worth roughly $5.74 billion.

The transaction code for the stock was filed under “G,” which stands for “Gift of securities by or to the insider” or “Bonafide gift.” Under “Explanation of Responses,” the filing reads: “Represent a bona fide gift of the Issuer’s common stock by the Reporting Person to charity.” The charity Elon Musk donated to was not revealed.
