New images from scientists at Cold Spring Harbor Laboratory (CSHL) reveal for the first time the three-dimensional structures of a set of molecules critical for healthy brain function.
The molecules are members of a family of proteins in the brain known as NMDA receptors, which mediate the passage of essential signals between neurons. The detailed pictures generated by the CSHL team will serve as a valuable blueprint for drug developers working on new treatments for schizophrenia, depression, and other neuropsychiatric conditions.
“This NMDA receptor is such an important drug target,” says Tsung-Han Chou, a postdoctoral researcher in CSHL Professor Hiro Furukawa’s lab. That’s because dysfunctional NMDA receptors are thought to contribute to a wide range of conditions, including not just depression and schizophrenia, but also Alzheimer’s disease, stroke, and seizures. “We hope our images, which visualize the receptor for the first time, will facilitate drug development across the field based on our structural information,” Chou says.
It’s important in sports and in interpersonal relationships—perfect timing. But how does our brain learn to estimate when events might occur and react accordingly? Scientists at MPI CBS in Leipzig together with colleagues from the Kavli Institute at the Norwegian University of Science and Technology in Trondheim were able to demonstrate in an MRI study that our brain learns best in connection with constructive feedback.
Imagine playing a game with friends, where they throw you a ball that you must catch. The first couple of throws you might miss the ball, but as you keep trying, you become better at estimating the time it takes to reach you and catch it more easily. How does your brain do this? “Fundamental to this process are your abilities to learn from past experiences and to extract time-related information from the environment,” explains Ignacio Polti, who conducted the study now published in the journal eLife together with Matthias Nau and Christian Doeller.
“Every throw of your friend will be slightly different from the previous one. Some balls arrive earlier, some arrive later. During the game, your brain learns the distribution of arrival times, and it uses this information to form expectations for future throws. By combining such prior knowledge with specific information of our friend’s current throw, we can thus improve the timing of our catch attempts.”
Research from a team of physicists at the University of New Hampshire is advancing the understanding of how protons, which comprise 95% of the mass of the visible universe, interact with each other. The results provide a benchmark for testing the strong force, one of the four fundamental forces in nature.
“There’s a lot still unanswered about both of those things, the proton and the strong force,” said David Ruth, Ph.D. candidate in physics and lead author. “This brings us a little bit closer to that understanding. It’s a necessary piece of two very fundamental things in the universe.”
The strong force governs how what’s internal to the atom’s nucleus—neutrons, protons and the quarks and gluons that make them up—bind together. It is the least understood of the four fundamental forces of nature, which include gravity, electromagnetism and the weak force.
New observations could explain why star formation declines over time.
And with the help of citizen scientists, a team of astronomers recently discovered a unique black hole in a galaxy roughly one billion light-years away that’s hurling a relativistic jet at another galaxy.
The research was conducted by a team led by Ananda Hota, a researcher with the UM-DAE Centre for Excellence in Basic Sciences. The paper that describes their findings was published on October 12th in the Monthly Notices of the Royal Astronomical Society Letters.

Researchers examining post-mortem brains confirm a long-held hypothesis explaining neurotransmitter’s connection to a debilitating disorder.
How does the brain chemical dopamine relate to schizophrenia? It is a question that vexed scientists for more than 70 years, and now researchers at the Lieber Institute for Brain Development (LIBD) believe they have solved the challenging riddle. This new understanding may lead to better treatment of schizophrenia, an often-devastating brain disorder characterized by delusional thinking, hallucinations, and other forms of psychosis.
Through their exploration of the expression of genes in the caudate nucleus – a region of the brain linked to emotional decision-making – the scientists uncovered physical evidence that neuronal cells are unable to precisely control levels of dopamine. They also identified the genetic mechanism that controls dopamine flow. Their findings were published today (November 1) in the journal Nature Neuroscience.

Tesla battery cell supplier Panasonic broke ground on a new lithium-ion battery manufacturing facility in De Soto, Kansas, contributing approximately 30 GWh of annual capacity in North America.
The facility is set to focus on rapidly ramping up the manufacture of 2,170 cylindrical cells to match surging domestic demand within the United States. Panasonic is planning to mass produce the battery cells by March 2025, and upon completion of the facility, it will add 30 GWh of capacity of battery supply to EV companies in the United States.
Quantum computers, which can perform calculations much faster than traditional computers, have a big problem: They are prone to data storage and processing errors caused by disturbances from the environment like vibrations and radiation from warm objects.
But a discovery by scientists led by Nanyang Technological University, Singapore (NTU Singapore), on how electrons can be controlled at very low temperatures, suggests a way for addressing this problem and developing more robust and accurate quantum computers.
The team’s findings, which were published online in the Nature Communications journal in October 2022, showed, for the first time, that electrons can have strong interactions between them under certain conditions.
