US researchers have observed a phenomenon known as ‘quantum superchemistry,’ in which ultracold atoms undergo chemical reactions at a faster rate than usual. The effect was predicted theoretically more than 20 years ago, but this is one of the first times the phenomenon been seen.

4 Billion Years Old – Earth’s Oldest-Known Rocks Provide Clues About Early Tectonics
new geochemical evidence obtained from Earth’s oldest-known rocks—found in remote lake regions of northern Canada—paints a starkly different picture of Earth’s earliest history.
“Our oldest samples show no sign of surficial material recycling at 4.0 Ga

Space dust has more organic contamination than the average US home
Levels of potentially harmful organic compounds in the dust aboard the International Space Station (ISS) are higher than those found in US and western European homes. It is the first time persistent organic chemicals have been detected in a non-terrestrial environment, and the team that carried out the analysis says that the findings will inform future material choices for manned spacecraft.

Europeans’ support for refugees of varying background is stable over time
We find that public preferences for asylum seekers with specific attributes have remained remarkably stable and general support has, if anything, increased slightly over time.

One woman's Orwellian experience with disinformation
After Nina Jankowicz's appointment to the Disinformation Governance Board was announced, she became a lightning rod and found herself on the receiving end of a very specific kind of online abuse: the kind that seems to be reserved for women. The attacks against her were as much about the idea of disinformation itself as they were about her qualifications

Scientists Uncover a Surprising Link Between Pure Mathematics and Genetics
The team found the maximal robustness of mutations—mutations that can occur without changing an organism’s characteristics—is proportional to the logarithm of all possible sequences that map to a phenotype, with a correction provided by the sums-of-digits function from number theory.

Genetic reasons behind Raynaud's phenomenon discovered
Around 2-5% of the population are affected by Raynaud's. Despite it being a common condition, it's under-investigated and little is understood about the genetic cause of the condition.

Mapped: Unemployed Workers vs. Job Openings, by U.S. State
In the United States, there were about 75 workers available for every 100 job openings as of July 2023. This means there is a significant gap between labor and jobs available, but also many opportunities present in some states for potential job seekers.

Microsoft resolves vulnerability following criticism from Tenable CEO
Microsoft has resolved a vulnerability that allows threat actors to gain access to information managed by Azure AD, a cloud offering used by large companies for managing user authentication.
Concerns about the issue burst into public view this week when Amit Yoran, the CEO of cybersecurity firm Tenable, published a scathing LinkedIn post bashing the tech giant for its handling of the vulnerability.
