Imagine being so greedy that you’re willing to sue someone because they aren’t as greedy as you.

The Mu2e experiment at Fermilab will look for a never-before-seen subatomic phenomenon that, if observed, would transform our understanding of elementary particles: the direct conversion of a muon into an electron. An international collaboration of over 200 scientists is building the Mu2e precision particle detector that will hunt for new physics beyond the Standard Model.

A Korean research team has developed a soft, mechanically deformable, and stretchable lithium battery that can be used in the development of wearable devices, and examined the battery’s feasibility by printing them on clothing surfaces. The research team, led by Dr. Jeong Gon Son from the Soft Hybrid Materials Research Center at the Korea Institute of Science and Technology (KIST; President: Seok-Jin Yoon), announced that they had developed a lithium battery wherein all of the materials, including the anode, cathode, current collector, electrolytes, and encapsulant, are stretchable and printable. The lithium battery developed by the team possesses high capacity and free-form characteristics suitable for mechanical deformation.

Owing to the rapidly increasing demand for high-performance wearable devices—such as smart bands, implantable electronic devices such as pace-makers, and soft wearable devices for use in the realistic metaverse—the development of a battery that is soft and stretchable like the human skin and organs has been attracting interest.

The hard, inorganic electrode of a conventional battery comprises the majority of the battery’s volume, making it difficult to stretch. Other components, such as the separator and the current collector for drawing and transferring charges, must also be stretchable, and the liquid electrolyte leakage issue must also be resolved.

Li and his colleagues found that the animals’ social ranking in the group was closely linked to the results of competition, and by examining recordings from neurons in the brains of mice in real time, the team discovered that neurons in the anterior cingulate region of the brain store this social ranking information to inform upcoming decisions.

“Collectively, these neurons held remarkably detailed representations of the group’s behavior and their dynamics as the animals competed together for food, in addition to information about the resources available and the outcome of their past interactions,” explains senior author Ziv M. Williams, MD, a neurosurgical oncologist at MGH. “Together, these neurons could even predict the animal’s own future success well before competition onset, meaning that they likely drove the animals’ competitive behavior based on whom they interacted with.”

Manipulating the activity of these neurons, on the other hand, could artificially increase or decrease an animal’s competitive effort and therefore control their ability to successfully compete against others. “In other words, we could tune up and down the animal’s competitive drive and do so selectively without affecting other aspects of their behavior such as simple speed or motivation,” says Williams.

Nearly 50 years after it was collected, a lunar sample from the Apollo 17 mission has finally been opened at NASA’s Johnson Space Center in Houston. It’s one of the last unopened samples from the final Apollo mission to land humans on the moon.

“We have had an opportunity to open up this incredibly precious sample that’s been saved for 50 years under vacuum and we finally get to see what treasures are held within,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington, in a statement.

It was collected by NASA astronauts Eugene Cernan and Harrison “Jack” Schmitt in December 1972 when they hammered 14-inch (36-centimeter) cylindrical drive tubes into a landslide deposit in the Taurus-Littrow Valley. The two astronauts vacuum-sealed the tube while still on the lunar surface.

Boston medical researchers in a new groundbreaking study have discovered a “vicious cycle” between daytime napping and Alzheimer’s dementia.

The Brigham and Women’s Hospital researchers found a link between the two: Excessive daytime napping predicted an increased future risk of Alzheimer’s dementia, and a diagnosis of Alzheimer’s dementia sped up the increase in daytime napping during aging.

Daytime napping is common among older adults, but researchers have not known the relationship between daytime napping and cognitive aging.

Techniques from computer science may help explain the tendency in biology for structures to repeat themselves.

The study could provide hope for people who have locked-in syndrome. But the study author’s track record is mired with controversy.
