Comet Leonard streaks across the field of view of the SoloHI telescope aboard ESA/NASA’s Solar Orbiter spacecraft on Dec. 17–19, 2021. The comet’s apparent backward movement is due to the spacecraft’s relative motion.

WHEN OLIVER TSCHAUNER AND COLLEAGUES dusted off a sample of volcano-ejected diamond found in a South African mine, they had no idea that they were holding the first-ever natural sample of a new high-pressure mineral from deep within Earth.
While minuscule, researchers predict that this mineral is responsible for the movement of crucial components like rare earth metals and radioactive isotopes through the Earth’s mantle. To figure this out, the team turned to X-ray beams and lasers.
Using x-rays and lasers, scientists have analyzed the second-ever high-pressure mineral extracted from the earth’s lower mantle.
“If you’re working on something that involves people or engineering, it’s probably a good focus for your future,” Musk.
Elon Musk has made many predictions about the future of society and the role that his companies Tesla and SpaceX will play. The millionaire has very strong opinions and is not afraid to express them in interviews, conferences, and even on social networks. This time, he spoke about the impact that Artificial Intelligence will have on the jobs of the future and mentioned the careers that will be safe. to the tech mogul, the essentials will be engineering and human-interactive careers.
The James Webb Space Telescope, NASA’s premier observatory of the next decade, successfully launched to space Saturday morning. The telescope will study exoplanets in new ways and look deeper into the universe than we’ve ever been able to before.
Analysis of ancient DNA from one of the best-preserved Neolithic tombs in Britain by a team involving archaeologists from Newcastle University, UK, and geneticists at the University of the Basque Country, University of Vienna and Harvard University, has revealed that most of the people buried there were from five continuous generations of a single extended family.

Although the right to use the tomb ran through patrilineal ties, the choice of whether individuals were buried in the north or south chambered area initially depended on the first-generation woman from whom they were descended, suggesting that these first-generation women were socially significant in the memories of this community.
There are also indications that ‘stepsons’ were adopted into the lineage, the researchers say — males whose mother was buried in the tomb but not their biological father, and whose mother had also had children with a male from the patriline. Additionally, the team found no evidence that another eight individuals were biological relatives of those in the family tree, which might further suggest that biological relatedness was not the only criterion for inclusion. However, three of these were women and it is possible that they could have had a partner in the tomb but either did not have any children or had daughters who reached adulthood and left the community so are absent from the tomb.
CRISPR-based cures will soon help combat all kinds of disease, from UTIs to leukemia. But terrifying implications of gene editing are abound as well.

The results of a meta-analysis suggest that probiotic supplementation may improve cognitive function in people with mild cognitive impairment.
Security researchers have uncovered a malicious campaign that relies on a valid code-signing certificate to disguise malicious code as legitimate executables.
One of the payloads that the researchers called Blister, acts as a loader for other malware and appears to be a novel threat that enjoys a low detection rate.
The threat actor behind Blister has been relying on multiple techniques to keep their attacks under the radar, the use of code-signing certificates being only one of their tricks.
The hidden water was found at a site as large as the Netherlands.
The water likely exists as ice, making the region ripe for future exploration.
