Human neurons have fewer ion channels, which might have allowed the human brain to divert energy to other neural processes.

Neurons communicate with each other via electrical impulses, which are produced by ion channels that control the flow of ions such as potassium and sodium. In a surprising new finding, MIT neuroscientists have shown that human neurons have a much smaller number of these channels than expected, compared to the neurons of other mammals.

The researchers hypothesize that this reduction in channel density may have helped the human brain evolve to operate more efficiently, allowing it to divert resources to other energy-intensive processes that are required to perform complex cognitive tasks.

More entanglements in the material help polymer chains slip without breaking.

We have also accumulated a very large collection of ritual objects, statues, thangkas, painting and drawings. Steve Nichols was initiated into the Kagyu tradition (Whispered Succession) although this collection (1,000’s of items) covers Bonpo and the other schools. exhibition

The path that led Jennifer Doudna, PhD, and her colleagues to the development of CRISPR, the gene-editing tool that has revolutionized science and earned her a Nobel Prize, started with their deep curiosity and drive to understand how the most basic building blocks of life function.

When Doudna first decided to investigate precisely what systems bacteria use to adapt their immune systems to fight off viral infections, she had little expectation that the findings would ultimately provide the key to technology that could be used to safely alter genetic code.

“All of us [on the research team] realized that what had started as a fundamental research question was morphing into a very different kind of project; namely, one with enormous technical potential and also risks and opportunities that we had not appreciated when we started the work,” Doudna explained during a conversation with J. Larry Jameson, MD, PhD, chair of the AAMC Board of Directors and executive vice president of the University of Pennsylvania Health System, at the opening plenary of Learn Serve Lead 2021: The Virtual Experience, on Monday, Nov. 8.

A CNS 2021 provided an incredible opportunity to learn more how the anatomy and integrity of brain networks impact higher-level cognition.

In the 19th and 20th century, cases of individuals with brain injury, such as Phineas Gage or Henry Molaison, have advanced our understanding of the relationship between the anatomy of the brain and its function. Back then, methods were limited to investigate whole-brain structure and function. Now, cognitive neuroscientists have some ability to visualize and measure activity of the whole brain at once, as well as the computational tools to investigate complex network-level relationships between brain structure, brain function, and behavior.

As a doctoral student working on stroke recovery, attending the CNS 2021 symposium led by Danielle Bassett was an incredible opportunity to learn more about some of the most recent methods that have been developed to understand how the anatomy and integrity of brain networks impact higher-level cognition. Strokes highly disrupt anatomical and functional connectivity, leading to cognitive and motor impairments. In individuals with post-stroke language impairments, namely aphasia, evidence shows that the more functional brain networks recover an organization similar to healthy individuals the better the recovery (Kiran et al., 2019). Understanding the relationship between brain structure and function in health and disease is therefore essential to develop appropriate treatments.

A new phase of matter, thought to be understandable only using quantum physics, can be studied with far simpler classical methods.

Researchers from the University of Cambridge used computer modeling to study potential new phases of matter known as prethermal discrete time crystals (DTCs). It was thought that the properties of prethermal DTCs were reliant on quantum physics: the strange laws ruling particles at the subatomic scale. However, the researchers found that a simpler approach, based on classical physics, can be used to understand these mysterious phenomena.

Understanding these new phases of matter is a step forward towards the control of complex many-body systems, a long-standing goal with various potential applications, such as simulations of complex quantum networks. The results are reported in two joint papers in Physical Review Letters and Physical Review B.

The study opens new avenues for the development of next-generation, highly sensitive X-ray detectors.
