"Scientists have discovered a virus that is a tiny bit human, carrying a gene it stole from our ancestors about 100,000 years ago," writes the New York Times. "And this virus may be using our own gene to infect us."

Phys.org explains that it's "both an important gene for brain function and a jumping gene capable of moving and inserting itself into genomes."


BC200 is found only in humans and related primates and was discovered in the late 1980s as an abundant noncoding RNA in human neurons. Although BC200's physiological function is poorly understood, evidence suggests it may be involved in regulating the translation of neuronal messenger RNAs into proteins... The researchers also suspect that BC200 jumped in skin cells because these are the only cells known to be infected by molluscum contagiosum virus (MCV). The gene is also abnormally expressed in some tumors and overexpressed in the brains of patients with Alzheimer's disease, suggesting its jumping ability could play roles in these diseases.
[Cedric Feschotte, a senior author of the study] said he and his colleagues would like to explore whether the molluscum contagiosum virus uses BC200 to manipulate human host cells. They are also interested in better understanding the gene's role in disease, including breast and other types of tumors in which it is abnormally expressed, and whether it jumps in cancer cells and causes mutations.

While most magnets have two poles (north and south, or positive and negative), recent advances in quantum mechanics have revealed an "octupolar order," writes Phys.org, where a pattern of particles in a crystalline structure "behaves as if it has eight magnetic poles rather than the familiar two."

Now, a team led by quantum physicists at the University of Toronto has established a new method for observing quantum magnetic states using light to probe the atomic vibrations produced as electrons spin. The work is a critical first step toward harnessing multipolar magnetism for practical technologies, including next-generation data storage and computing devices.
"We identified new signatures of a hidden type of magnetic state which cannot be detected using ordinary probes," says Arun Paramekanti, a professor in the Department of Physics and the Center for Quantum Information & Quantum Control in the Faculty of Arts & Science at the University of Toronto, and senior author of a study published in Physical Review Letters that describes the findings.
"Our research opens up the possibility for using higher-order magnets in several applications including controllable read-write memory elements found in everyday computers...."

By directing a special type of rotating light at magnetic materials, the team observed a clear optical fingerprint of the otherwise hidden magnetic order.... The findings offer a new tool for uncovering and manipulating previously inaccessible forms of magnetism, opening new avenues for quantum technology development.

404 Media reports:


"We will not add facial recognition to our devices," Flock CEO Garrett Langley said in a recent video. But other, third-party companies are telling cops that they are willing to add facial recognition to data gathered by Flock cameras in order to "close that gap." A company called VIDIZMO is advertising the capability to export footage from FlockOS to its own platforms that do facial recognition, behavior prediction, and racial and gender analysis on live camera feeds. VIDIZMO is a several decades-old video analysis and database company that has started offering facial recognition technology to cops within the last six months. In a May email to Johnson City, Tennessee, deputy police chief Michael Adams, a salesperson from VIDIZMO wrote that the company's product could do facial recognition on both Flock and Axon [body-worn camera] data in "one searchable platform...."

VIDIZMO's CEO, Nadeem Khan, told 404 Media on a video call that the company has not yet started running facial recognition tech on footage from Flock cameras, and that it has not actually built the specific tool that would export data from Flock's system to its own platform (though the company advertises this capability online, and the company already sells other facial recognition products). But Khan said VIDIZMO "would love to do the integration," and that he believes facial recognition "is the way the world is going, the way the world will have to be," and that he thinks Flock should offer the capability itself in a way that "balances privacy, security, and the freedom that we enjoy in this country."



The article notes that VIDIZMO says on its website, "You can identify individuals from seven races: White, Black, Indian, East Asian, Southeast Asian, Middle Eastern, and Latino Hispanic." VIDIZMO adds that stores or cities can also then do "demographic analysis" for marketing purposes by determining the races or ages of people showing up....
