Tendon Stem Cells could Revolutionize Injury Recovery

This image shows the Patellar tendon 30 days after an injury. The red marks newly discovered tendon stem cells that have self-renewed and are layered over green marked, original tendon cells. During regeneration, some tendon stem cells differentiate to make newly regenerated tendon cells—a process during which they transition into a yellow-orange color. The blue indicates cellular nuclei.

Discovery of tendon stem cells could be a game-changer when it comes to treating tendon injuries, avoiding surgery. The buildup of scar tissue makes recovery from torn rotator cuffs, jumper’s knee, and other tendon injuries a painful, challenging process, often leading to secondary tendon ruptures...

Molecular Eraser enables better Data Storage and Computers for AI

Abstract Image
Detecting and Directing Single Molecule Binding Events on H-Si(100) with Application to Ultradense Data Storage

Scientists have added a crucial tool to the atomic-scale manufacturing toolkit with major implications for today’s data driven—carbon intensive—world, according to new research from the University of Alberta in Canada.

“Computers today are contributing one gigatonne of carbon emissions to the atmosphere, and we can eliminate that by enhancing the most power-hungry parts of conventional computers with our atomic-scale circuitry,” said Robert Wolkow, professor in the University of Alberta’s Department of Physics a Principal Research Officer at the National Research Council of Canada’s Nanotechnology Research Centre, and chief technical officer of Quantum Silicon Inc, a...

A new theory for how Black Holes and Neutron Stars Shine Bright

Here, a massive super-computer simulation shows the strong particle density fluctuations that occur in the extreme turbulent environments that host black holes and neutron stars. Dark blue regions are low particle density regions, while yellow regions are strongly over-dense regions. Particles are accelerated to extremely high speeds due to the interactions with strongly turbulence fluctuations in this environment. Credit: Image from published study

Astrophysicists employed massive super-computer simulations to calculate the mechanisms that accelerate charged particles in extreme environments. They concluded their energization is powered by the interplay of chaotic motion and reconnection of super-strong magnetic fields.

For decades, scientists have speculated about the origin of ...

It’s Never Too Late to Start Exercising, new study shows

Comparable Rates of Integrated Myofibrillar Protein Synthesis Between Endurance-Trained Master Athletes and Untrained Older IndividualsFrontiers in Physiology, 2019; 10 DOI: 10.3389/fphys.2019.01084

Older people who have never taken part in sustained exercise programmes have the same ability to build muscle mass as highly trained master athletes of a similar age, according to new research at the University of Birmingham. The research shows that even those who are entirely unaccustomed to exercise can benefit from resistance exercises such as weight training.

In the study, published in Frontiers in Physiology, researchers in the University of Birmingham’s School of Sport and Exercise Science compared muscle-building ability in two groups of older men...
