A University of Minnesota research team has made mind-reading possible through the use of electronics and AI.

Researchers at the University of Minnesota Twin Cities have created a system that enables amputees to operate a robotic arm using their brain impulses rather than their muscles. This new technology is more precise and less intrusive than previous methods.

Science and technology have advanced incredibly in the 21st Century. It’s easier now than ever to travel to or talk to people who live halfway across the world, and we now are more connected to advanced technology than anyone could have thought possible. Science fiction, in the 20th and 21st Centuries, has strived to anticipate just how far this technological advancement would go, and what the consequences of that would be.

Of course, a lot of old sci-fi movies included tropes about the 21st Century that proved to be wrong. Indeed, it was probably too optimistic, in hindsight, to assume we would get flying cars before the end of the 90s or that the 2000s would have lifelike androids running around. Despite these incorrect predictions, though, there are some movies that were eerily accurate, or even predicted we would have technology later than we eventually got access to. In some cases, sci-fi has even been the inspiration for invention, with people wanting to emulate what they saw on television. These are some predictions, made by older sci-fi movies, that turned out to be on the money.

Fourteen of the leaked recordings include conversations with or about a team of consultants from Booz Allen Hamilton. One of the consultants told TikTok employees that they were brought on in February 2021 to help manage the Project Texas data migration, and a TikTok director told other TikTok employees that the consultants reported to TikTok’s chief of US data defense. In recordings, the consultants investigate how data flows through TikTok and ByteDance’s internal tools, including those used for data visualization, content moderation, and monetization.

In September 2021, one consultant said to colleagues, “I feel like with these tools, there’s some backdoor to access user data in almost all of them, which is exhausting.”

New hope for therapy against retinitis pigmentosa.

Electrons are some of the most basic building components of matter that we are familiar with. They have several distinguishing characteristics, including a negative charge and the existence of an exact intrinsic angular momentum, often known as spin. Each electron, as a charged particle with spin, has a magnetic moment that aligns in a magnetic field as a compass needle does.

Quantum electrodynamics can forecast the strength of this magnetic moment, which is given by the so-called g-factor, with incredible accuracy. This computation agrees to within 12 digits with the empirically determined g-factor, making it one of the most precise theory-experiment matches in physics to date. The magnetic moment of the electron, on the other hand, changes when it is no longer a “free” particle, that is, when it is linked to an atomic nucleus, for example. QED, which defines the interaction between electrons and nucleus in photon exchange, can be used to determine minor changes in the g-factor. This notion can be sensitively tested thanks to high-precision measurements.

In a new study, scientists at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg successfully investigated QED predictions with unprecedented resolution. They used a newly developed technique to measure a very small difference in the magnetic properties of two isotopes of highly charged neon in an ion trap with previously inaccessible accuracy.

Scientists have created the first reference charts for the human brain, mapping its growth from infancy to 100 years old. Now, they have to grapple with difficult ethical questions about how they should — and perhaps shouldn’t — be used.

The reference charts are visualizations created from aggregating analyses of over 120,000 brain scans to show ranges in brain size, or gray matter volume, for each age. They also track the human brain’s rapid expansion early in life and its gradual shrinking over time. The researchers primarily developed the charts to provide a standardized measurement that other neuroscientists could use for brain imaging research, with the hope that maybe one day it could lead to a tool used in clinics.

“It’s an absolutely spectacular advancement in neuroscience and neuroimaging,” said Judy Illes, professor of neurology and neuroethics at the University of British Columbia.

A new approach to the organ transplant procedure devised by researchers at Stanford University and their collaborators minimizes the risk of organ rejection, ScienceAlert reported. Moreover, the technique does not require the organ recipient to remain immune-compromised after the procedure.

The first successful solid organ transplant was that of a kidney in 1954, and the world has not looked back. Modern medicine is now able to transplant eyes, liver, kidneys as well as heart, procedures which are saving lives the world over. To tide over the shortages of organs that are available for transplantation, companies are even rearing genetically modified pigs to be safely transplanted in the future.

A Google engineer who was suspended after he said the company’s artificial intelligence chatbot had became sentient says he based the claim on his Christian faith.

Blake Lemoine, 41, was placed on paid leave by Google earlier in June after he published excerpts of a conversation with the company’s LaMDA chatbot that he claimed showed the AI tool had become sentient.

Now, Lemoine says that his claims about LaMDA come from his experience as a “Christian priest” — and is accusing Google of religious discrimination.
