Astronomers Finally Explain How Molecules From Earth's Atmosphere Keep Winding Up On the Moon
An anonymous reader shared this report from CNN:
Particles from Earth's atmosphere have been carried into space by solar wind and have been landing on the moon for billions of years, mixing into the lunar soil, according to a new study [published in the journal Nature Communications Earth & Environment last month]. The research sheds new light on a puzzle that has endured for over half a century since the Apollo missions brought back lunar samples with traces of substances such as water, carbon dioxide, helium and nitrogen embedded in the regolith — the moon's dusty surface layer.
Early studies theorized that the sun was the source of some of these substances. But in 2005 researchers at the University of Tokyo suggested that they could have also originated from the atmosphere of a young Earth before it developed a magnetic field about 3.7 billion years ago. The authors suspected that the magnetic field, once in place, would have stopped the stream by trapping the particles and making it difficult or impossible for them to escape into space. Now, the new research upends that assumption by suggesting that Earth's magnetic field might have helped, rather than blocked, the transfer of atmospheric particles to the moon — which continues to this day.
"This means that the Earth has been supplying volatile gases like oxygen and nitrogen to the lunar soil over all this time," said Eric Blackman, coauthor of the new study and a professor in the department of physics and astronomy at the University of Rochester in New York.
Earth's magnetic field "somewhat inflates the atmosphere of Earth" when it's hit by solar winds, according to study coauthor Eric Blackman, a physics/astronomy professor at New York's University of Rochester. He told CNN the moon passes through this region for a few days each month, with particles landing on the lunar surface and embedding in the soil (because the moon lacks an atmosphere that would block them).
This also means the moon's soil could actually contain a chemical record of Earth's ancient atmosphere, according to the study — "spanning billions of years..."

Acer Sues Verizon, AT&T, and T-Mobile, Alleging Infringment on Acer's Cellular Networking Patents
Slashdot reader BrianFagioli writes: Acer has filed three separate patent infringement lawsuits against AT&T, Verizon, and T-Mobile, taking the unusual step of hauling the nation's largest wireless carriers into federal court. The suits, filed in the Eastern District of Texas, claim the companies are using Acer-developed cellular networking technology without paying for the privilege. Acer says it tried to negotiate licenses for years but reached a dead end, arguing it was left with no option except litigation. The case centers on six U.S. patents Acer asserts are core to modern wireless networks, rather than anything tied to PCs or laptops. The company describes itself as reluctant to pursue courtroom battles, but it has been quietly building a large global patent portfolio after pouring hundreds of millions of dollars into R&D. Acer also notes that some of its patents count as standard-essential, hinting the carriers may be required to license them. All three companies are expected to push back, and the dispute could become another long-running telecom patent saga. Consumers will not notice any immediate changes, but if Acer wins or settles, it may find a new revenue stream far beyond its traditional hardware business.

China Builds 'Hypergravity' Machine 2,000X Stronger Than Earth
Long-time Slashdot reader schwit1 shared this report from Futurism:
China has unveiled an extremely powerful "hypergravity machine" that can generate forces almost two thousand times stronger than Earth's regular gravity.
The futuristic-looking machine, called CHIEF1900, was constructed at China's Centrifugal Hypergravity and Interdisciplinary Experiment Facility (CHIEF) at Zheijang University in Eastern China, and allows researchers to study how extreme forces affect various materials, plants, cells, or other structures, as the South China Morning Post reports... [Once up and running, it will allow researchers to recreate "catastrophic events such as dam failures and earthquakes inside a laboratory, according to the university."] For instance, it can analyze the structural stability of an almost 1,000-feet-tall dam by spinning a ten-foot model at 100 Gs, meaning 100 times the Earth's regular gravity. It could also be used to study the resonance frequencies of high-speed rail tracks, or how pollutants seep into soil over thousands of years.
The machine officially dethroned its predecessor, CHIEF1300, which became the world's most powerful centrifuge a mere four months ago... It can generate 1,900 g-tonnes of force, or 1,900 times the Earth's gravity. To put that into perspective, a washing machine only reaches about two g-tonnes.
