Nano particles for healthy tissue

"Eat your vitamins" might be replaced with "ingest your ceramic nano-particles" in the future as space research is giving more weight to the idea that nanoscopic particles could help protect cells from common causes of damage.

Rodents and a rocket carried these researchers' dreams to space

The human body evolved within the constant force of Earth's gravity. To prevent bone and muscle atrophy during their stays in space, astronauts must exercise every day. For researchers studying bone or muscle loss that might ...

Learning from the bears

Grizzly bears spend many months in hibernation, but their muscles do not suffer from the lack of movement. In the journal Scientific Reports, a team led by Michael Gotthardt reports on how they manage to do this. The grizzly ...

Discovery of neutron star collision is 'breakthrough' of 2017

The world's first-ever detection of two faraway neutron stars colliding, causing a massive blast that rippled through the fabric of space and time, was judged the scientific breakthrough of 2017, the journal Science said ...

Cells in space

Laboratories on Earth hardly make the news, unless they come up with life-saving cures. So why would anyone care about a lab in space? The medicine you take on Earth begins with cell research, and the latest experiments on ...

Working out in artificial gravity

Astronauts on the International Space Station (ISS) have a number of exercise options, including a mechanical bicycle bolted to the floor, a weightlifting machine strapped to the wall, and a strap-down treadmill. They spend ...

Atrophy

Atrophy is the partial or complete wasting away of a part of the body. Causes of atrophy include poor nourishment, poor circulation, loss of hormonal support, loss of nerve supply to the target organ, disuse or lack of exercise or disease intrinsic to the tissue itself. Hormonal and nerve inputs that maintain an organ or body part are referred to as trophic.

Atrophy is a general physiological process of reabsorption and breakdown of tissues, involving apoptosis on a cellular level. When it occurs as a result of disease or loss of trophic support due to other disease, it is termed pathological atrophy, although it can be a part of normal body development and homeostasis as well.
