NASA Demands Return of Moon Dust Pooped Out by Cockroaches
No Takebacks Moon dust that was digested and recovered from cockroach carcasses probably isn't going to a new home, after all. Back in May, news broke that a private collector was selling a small amount of lunar dirt left from the Apollo 11 mission that astronauts brought back in 1969. In a series of experiments involving fish and other animals, the private collector got their hands on dirt that

We're in Awe of this Absolutely Deranged "Nuclear-Powered Sky Hotel"
Howl's Nuclear Castle It's definitely not a bird, but it is sort of a plane. Specifically, it's a non-existent but admittedly very cool concept called the Sky Cruise, a fantastical nuclear-powered sky hotel. The impressively-detailed video rendering visualizes a hulking airborne vessel, allegedly designed to house over 5,000 guests in nearly nonstop flight. Alongside magnificent views of nature —

Stranded Oil Tanker That Could Start Leaking Any Time Now, Experts Warn
Time Bomb In some of the week's worst environmental news, a stranded oil tanker off the coast of Yemen could make the 1989 Exxon Valdez oil spill "look like a beach party," according to a Bloomberg op-ed published yesterday. The tanker holds 1.1 million barrels of oil and is pretty much a done-in rust bucket doing its best to stay afloat. In May, Al Jazeera reported that the tanker's "structural

Mmm-k scale climate models
Ocean eddy visualization ( Karsten Schnieder ) Two opinion pieces ( Slingo et al. , and Hewitt et al. ) and a supportive Nature Climate Change editorial were published this week, extolling the prospects for what they call "k-scale" climate modeling.

COVID-19 disease severity in US Veterans infected during Omicron and Delta variant predominant periods
Nature Communications, Published online: 25 June 2022; doi:10.1038/s41467-022-31402-4 Infection with the SARS-CoV-2 Omicron variant appears to cause milder disease in the general population than infection with Delta.

Detection of SARS-CoV-2 intra-host recombination during superinfection with Alpha and Epsilon variants in New York City
Nature Communications, Published online: 25 June 2022; doi:10.1038/s41467-022-31247-x Here, the authors characterize a case of SARS-CoV-2 superinfection with Alpha and Epsilon variants, in which, via full genome sequencing analyses, they identify recombinant haplotypes in the spike, nucleocapsid, and ORF 8 coding regions, suggesting recombination could play a role in SARS-CoV-2 genetic diversity.

FANCM promotes class I interfering crossovers and suppresses class II non-interfering crossovers in wheat meiosis
Nature Communications, Published online: 25 June 2022; doi:10.1038/s41467-022-31438-6 The FANCM helicase functions in limiting crossovers (COs) by unwinding inter-homolog repair intermediates. Here, the authors generate null mutants of fancm in tetraploid and hexaploid wheat and show that FANCM promotes class I interfering COs and suppresses class II noninterfering COs in wheat meiosis.

Investigating the dynamics that reshape permafrost environments
When permafrost thaws, water can flow more quickly through the ground, creating a complex subsurface flow system. Researchers at the Barrow Environmental Observatory in Alaska gained insight into this process by taking daily measurements of the electrical resistivity of the ground. The results show that vegetation and the snowpack that accumulates on the vegetation in winter control the temperatur
