Ageing in Human Cells Successfully Reversed in the Lab

Posted by in categories: biotech/medical, life extension, neuroscience

The ability to reverse ageing is something many people would hope to see in their lifetime. This is still a long way from reality, but in our latest experiment, we have reversed the ageing of human cells, which could provide the basis for future anti-degeneration drugs.

Ageing can be viewed as the progressive decline in bodily function and is linked with most of the common chronic diseases that humans suffer from, such as cancer, diabetes and dementia. There are many reasons why our cells and tissues stop functioning, but a new focus in the biology of ageing is the accumulation of “senescent” cells in the tissues and organs.

Senescent cells are older deteriorated cells that do not function as they should, but also compromise the function of cells around them. Removal of these old dysfunctional cells has been shown to improve many features of ageing in animals such as the delayed onset of cataracts.

Scientists clone virus to help stop overwhelming grape disease

Posted by in category: biotech/medical

A new discovery by Washington State University scientists could help grape growers roll back a devastating virus that withers vines and shrivels harvests.

Named for how it curls the leaves of infected plants, grapevine leafroll disease costs growers millions of dollars in lost vines and productivity. Until now, no one has been able to replicate one of the main culprits behind the disease, a called grapevine leafroll-associated virus 3—leafroll 3, for short.

For the first time, researchers in WSU’s Department of Plant Pathology have found a way to clone leafroll 3, opening the door for experiments and treatments to protect valuable Washington vineyards.

Why Technology Favors Tyranny

Posted by in categories: biotech/medical, robotics/AI

The revolutions in information technology and biotechnology are still in their infancy, and the extent to which they are responsible for the current crisis of liberalism is debatable. Most people in Birmingham, Istanbul, St. Petersburg, and Mumbai are only dimly aware, if they are aware at all, of the rise of AI and its potential impact on their lives. It is undoubtable, however, that the technological revolutions now gathering momentum will in the next few decades confront humankind with the hardest trials it has yet encountered.


Artificial intelligence could erase many practical advantages of democracy, and erode the ideals of liberty and equality. It will further concentrate the power among a small elite if we don’t take steps to stop it.

Liver disease drug could help restore cells damaged

Posted by in categories: biotech/medical, neuroscience

A drug which has been used to treat liver disease for decades could help to restore cells damaged by Alzheimer’s, a new study from the University of Sheffield has found.

The pioneering study, funded by Alzheimer’s Research UK, discovered the drug ursodeoxycholic acid (UDCA) improves mitochondrial dysfunction – which is known to be a causative factor for both sporadic and familial Alzheimer’s disease.

Mitochondria play a pivotal role in both neuronal cell survival and death as they regulate energy metabolism and cell death pathways acting as a cell’s battery.

Scientists Have Found Secret Tunnels Between The Skull And The Brain

Posted by in categories: biotech/medical, neuroscience

Did you know you have tiny tunnels in your head? That’s OK, no one else did either until recently! But that’s exactly what a team of medical researchers have just found in mice and humans — tiny channels that connect skull bone marrow to the lining of the brain.

The research shows they may provide a direct route for immune cells to rush from the marrow into the brain in the event of damage.

Previously, scientists had thought immune cells were transported via the bloodstream from other parts of the body to deal with brain inflammation following a stroke, injury, or brain disorder.

A recipe for regenerating nerve fibers across complete spinal cord injury

Posted by in category: biotech/medical

Scientists have designed a three-stepped recipe for regenerating electro-physiologically active nerve fibers across complete spinal cord lesions in rodents. Rehabilitation is still required to make these new nerve fibers functional for walking.
