The narrow groove theory was proposed in 1965 by J. H. Vohr and C. Y. Chow, two engineers at New York-based Mechanical Technology, Inc. The theory explains the working of herringbone grooved journal bearings, or HGJBs – a type of air-lubricated bearing that supports rotating parts in mechanical systems.

Many different types of bearings exist, but HGJBs hold the most promise for developing ultrahigh-speed rotating machines because the rotor is supported on a cushion of air generated by the rotating shaft.

Carbon locked in soils can be emitted by bacteria. Turning up the heat on them releases more carbon.

“We expect that [T Coronae Borealis] will erupt any night now, any month now,” Bradley Schaefer, a Louisiana State University astronomer, said.

CTSC-activated fluorescence probes enable rapid sorting of benign/malignant breast tumors.

Researchers categorized participants by whether or not they had experienced SCD, and by their antidepressant medication use — between 1 and 5 years, or 6 years and longer.

At the study’s conclusion, researchers found that participants who used antidepressants for a period of 1 to 5 years had a 56% increased risk of SCD.

Participants who used antidepressants for 6 or more years had a 2.2 times higher risk for SCD.

Our electrical infrastructure is built on copper, placing this metal at the core of the energy transition. But sluggish supply could compromise ambitions to decarbonize the energy sector.

The SpotBugs maintainer has since confirmed that the PAT that was used as a secret in the workflow was the same access token that was later used to invite “jurkaofavak” to the “spotbugs/spotbugs” repository. The maintainer has also rotated all of their tokens and PATs to revoke and prevent further access by the attackers.

One major unknown in all this is the three-month gap between when the attackers leaked the SpotBugs maintainer’s PAT and when they abused it. It’s suspected that the attackers were keeping an eye out on the projects that were dependent on “tj-actions/changed-files” and waited to strike a high-value target like Coinbase.

“Having invested months of effort and after achieving so much, why did the attackers print the secrets to logs, and in doing so, also reveal their attack?,” Unit 42 researchers pondered.
