One potential application: Enhancing the sensitivity of atomic magnetometers used to measure the alpha waves emitted by the human brain.

Scientists are increasingly seeking to discover more about quantum entanglement, which occurs when two or more systems are created or interact in such a manner that the quantum states of some cannot be described independently of the quantum states of the others. The systems are correlated, even when they are separated by a large distance. Interest in studying this kind of phenomenon is due to the significant potential for applications in encryption, communications, and quantum computing.

Performing computation using quantum-mechanical phenomena such as superposition and entanglement.

It’s an early step forward and needs way more testing. But the potential is high. Cancer vaccines aren’t a new idea. They use the same fundamentals that enable vaccines for infectious pathogens like viruses and bacteria: priming our immune system into recognizing and attacking something that’s harmful to our bodies.

If you’ve ever thought your children in elementary school were “smarter” than you, or at least quicker at taking up new skills and knowledge, new research published in the journal Current Biology confirms that you were correct. According to the new study, there are differences in the brain messenger GABA between kids and adults, which may explain why kids often seem to be more capable of learning and retaining new information.

“Our results show that children of elementary school age can learn more items within a given period of time than adults, making learning more efficient in children,” said Takeo Watanabe of Brown University.

According to the study, children experienced a rapid increase in GABA during visual training, which lasted even after the training ended. In contrast, GABA concentrations in adults remained constant during training. These findings suggest that children’s brains are more responsive to training, allowing them to quickly and efficiently consolidate new learning.

Nuclear physicists have found a new way to use the Relativistic Heavy Ion Collider (RHIC)—a particle collider at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory—to see the shape and details inside atomic nuclei. The method relies on particles of light that surround gold ions as they speed around the collider and a new type of quantum entanglement that’s never been seen before.

Through a series of quantum fluctuations, the particles of light (a.k.a. photons) interact with gluons—gluelike particles that hold quarks together within the protons and neutrons of nuclei. Those interactions produce an intermediate particle that quickly decays into two differently charged “pions” (π). By measuring the velocity and angles at which these π⁺ and π^- particles strike RHIC’s STAR detector, the scientists can backtrack to get crucial information about the photon—and use that to map out the arrangement of gluons within the nucleus with higher precision than ever before.

“This technique is similar to the way doctors use positron emission tomography (PET scans) to see what’s happening inside the brain and other body parts,” said former Brookhaven Lab physicist James Daniel Brandenburg, a member of the STAR collaboration who joined The Ohio State University as an assistant professor in January 2023. “But in this case, we’re talking about mapping out features on the scale of femtometers —quadrillionths of a meter—the size of an individual proton.”

Scientists at Imperial College London, UK have proved that a modern surgical knife dubbed iKnife can “smell tumours”, effectively detecting womb cancer within seconds. The breakthrough could enable thousands of women to get an earlier cancer diagnosis.

“The iKnife reliably diagnosed endometrial cancer in seconds, with a diagnostic accuracy of 89%, minimising the current delays for women whilst awaiting a histopathological diagnosis,” said the researchers in the finding published in the journal Cancers.

Notably, the iKnife is already being used to treat breast and brain cancers, reported the Guardian, and now it can also accurately detect the presence of endometrial cancer.

Retinal cells grown from stem cells can reach out and connect with neighbors, according to a new study, completing a “handshake” that may show the cells are ready for trials in humans with degenerative eye disorders.

Australian scientists have created the most detailed map ever of the communication links between the hippocampus, the brain’s memory control center, and the rest of the brain, potentially revolutionizing our understanding of human memory.

“We were surprised to find fewer connections between the hippocampus and frontal cortical areas, and more connections with early visual processing areas than we expected to see,” said Dr. Marshall Dalton, a Research Fellow in the School of Psychology at the University of Sydney. “Although, this makes sense considering the hippocampus plays an important role not only in memory but also imagination and our ability to construct mental images in our mind’s eye.”

New research published in the Annals of Clinical and Translational Neurology on December 7 has identified three genes and their expressed proteins that may be involved in the pathogenesis of multiple sclerosis.

By comparing information on the genes and proteins expressed in the brains of thousands of individuals with and without multiple sclerosis, investigators discovered different expression levels of the SHMT1, FAM120B, and ICA1L genes (and their proteins) in brain tissues of patients versus controls.

Studying the functions of these genes may uncover new information on the mechanisms involved in the development and progression of multiple sclerosis. “Our findings shed new light on the pathogenesis of MS and prioritized promising targets for future therapy research,” the authors wrote.
