Cell Protein Discovery points to Healthier Aging

Researchers at The University of Queensland have found an anti-ageing function in a protein deep within human cells.

Associate Professor Steven Zuryn and Dr Michael Dai at the Queensland Brain Institute have discovered that a protein called ATSF-1 controls a fine balance between the creation of new mitochondria and the repair of damaged mitochondria.

Mitochondria, with their own DNA, produce energy within cells to power biological functions but the toxic by-products of this process contribute to the rate at which the cell ages.

“In conditions of stress, when mitochondrial DNA has been damaged, the ATSF-1 protein prioritises repair which promotes cellular health and longevity,” Dr Zuryn said.

As an analogy, Dr Zuryn likened the relationship to a race car needing...

Bot inspired by Baby Turtles can Swim Under the Sand

The robot is equipped with flipper-like appendages that allow it to move under the sand.
The robot is equipped with flipper-like appendages that allow it to move under the sand. 

This robot can swim under the sand and dig itself out too, thanks to two front limbs that mimic the oversized flippers of turtle hatchlings.

It’s the only robot that is able to travel in sand at a depth of 5 inches. It can also travel at a speed of 1.2 millimeters per second-roughly 4 meters, or 13 feet, per hour. This may seem slow but is comparable to other subterranean animals like worms and clams. The robot is equipped with force sensors at the end of its limbs that allow it to detect obstacles while in motion. It can operate untethered and be controlled via WiFi.

Robots that can move through sand face significant challenges like dealing with higher forces than robots that move in air or...

Researchers Operating Gamma-ray Burst Monitor Discover Brightest Gamma-ray Burst ever detected

Astronomers believe Gamma-Ray Burst 221009A represents the birth of a new black hole formed within the heart of a collapsing star. In this illustration, the black hole drives powerful jets of particles traveling near the speed of light. The jets pierce through the star, emitting X-rays and gamma rays as they stream into space. Gamma-ray bursts are the most powerful explosions in the universe. They emit most of their energy in gamma rays, light which is many times more energetic than the visible light we can see with our eyes. Courtesy NASA

The University of Alabama in Huntsville (UAH) has announced that three researchers associated with the UAH Center for Space Plasma and Aeronomic Research (CSPAR) have discovered a gamma-ray burst (GRB) approximately 2...

Magnetic activity plays key role in exoplanet habitability. Astronomers have found evidence that some stars boast unexpectedly strong surface magnetic fields, a discovery that challenges current models of how they evolve.

In stars like our sun, surface magnetism is linked to stellar spin, a process similar to the inner workings of a hand-cranked flashlight. Strong magnetic fields are seen in the hearts of magnetic sunspot regions, and cause a variety of space weather phenomena...
