A new biological mechanism to regenerate and repair myelin

Posted by in categories: biological, neuroscience

A neonatal hypoxic-injury animal model revealed that CK2α mediated Daam2 phosphorylation, which plays a protective role in developmental and behavioral recovery after neonatal hypoxia, a form of brain injury seen in cerebral palsy and other conditions. Additionally, it facilitates remyelination after white matter injury in adult animals.

Together, these findings have identified a novel regulatory node connecting CK2α and Daam2 in the Wnt pathway that regulates stage-specific oligodendrocyte development and offers insights into a new biological mechanism to regenerate myelin.

“This study opens exciting therapeutic avenues we could develop in the future to repair and restore myelin, which has the potential to alleviate and treat several neurological issues that are currently untreatable,” Lee said.

Scientists Have Made a Discovery That Could Change Our Understanding of the Universe

Posted by in categories: biological, chemistry, physics, space

Researchers from Queen Mary University of London have made a discovery that could change our understanding of the universe. In their study published on August 23 in the journal Science Advances.

<em>Science Advances</em> is a peer-reviewed, open-access scientific journal that is published by the American Association for the Advancement of Science (AAAS). It was launched in 2015 and covers a wide range of topics in the natural sciences, including biology, chemistry, earth and environmental sciences, materials science, and physics.

New experimental research measures the speed of molecular charge migration for the first time

Posted by in categories: biological, chemistry, quantum physics

To discover how light interacts with molecules, the first step is to follow electron dynamics, which evolve at the attosecond timescale. The dynamics of this first step have been called charge migration (CM). CM plays a fundamental role in chemical reactions and biological functions associated with light–matter interaction. For years, visualizing CM at the natural timescale of electrons has been a formidable challenge in ultrafast science due to the ultrafine spatial (angstrom) and ultrafast temporal (attosecond) resolution required.

Experimentally, the sensitive dependence of CM on and orientations has made the CM dynamics complex and difficult to trace. There are still some open questions about molecular CM that remain unclear. One of the most fundamental questions: how fast does the charge migrate in molecules? Although molecular CM has been extensively studied theoretically in the last decade by using time-dependent quantum chemistry packages, a real measurement of the CM has remained unattainable, due to the extreme challenge.

As reported in Advanced Photonics, a research team from Huazhong University of Science and Technology (HUST), in cooperation with theoretical teams from Kansas State University and University of Connecticut, recently proposed a high harmonic spectroscopy (HHS) method for measuring the CM speed in a carbon-chain molecule, butadiyne (C4H2).

Future computers could be built using proteins that make up cells

Posted by in categories: biological, computing

Future computers could be built smaller than ever before using the tiny biological skeletons that hold our cells together.

That’s according to one team of scientists, who have devised a way to make computer chips using cytoskeletons — protein scaffolds that give cells their shape.

Soft robotics research offers new route for weaving soft materials into 3D spatial structures

Posted by in categories: biological, robotics/AI

Ever wonder why the most advanced robots always seem to have hard bodies? Why not more pliable ones, like humans have?

Researchers working on so-called “soft robotics” attempt to incorporate the feel of living organisms into their creations. But the field hasn’t taken off because the softer components haven’t been easy enough to mass-produce and incorporate into the designs—until now.

University of Virginia researchers have invented a for weaving such as fabrics, rubbers and gels so that they can be compatible with gadgets, which may lead to a soft robotics revolution.

An Incredible New Crystal Can Transform Light Into Mechanical Work

Posted by in categories: biological, chemistry, engineering

Almost all forms of modern consumer technology are powered by electrochemical energy, otherwise known as batteries. Lithium-ion batteries, for example, transform chemical reactions into direct current energy while also producing a few side effects (mainly heat). But what if there was another way to power gadgets—say, lasers?

That’s the idea behind new research from the Department of Chemical and Biological Engineering and CU-Boulder. In a new study published this month in the journal Nature Materials, the team—led by chemical and electrical engineering professor Ryan Hayward—explored ways to leverage tiny crystals and directly transform light into mechanical work. At scale, such a breakthrough could remove the need for bulky batteries and all of the thermal management that comes with it.

Facing Our Transhuman Future

Posted by in categories: biological, evolution, singularity, transhumanism

Does our increasing dependency on technology diminish our human potential? In this episode, visionary scientist Gregg Braden discusses the current transhuman movement – the merging of technology and human biology, often referred to as the singularity. He describes three levels of tech integration where the final level replaces our natural biology. In a time of rapid evolution, reflection and discernment are key. Braden highlights what we can do to release the conditioning of a technology-dependent society and how to follow the natural rhythms within ourselves.
