Axolotls Can Regenerate Their Own Brains: New research maps out the different cell types hoping to pave the way to regenerative medicine!

Several antiviral drugs kill viruses by inducing lots of mutations, but a computer model suggests this could have unpredictable consequences.
A team of researchers at the University of Illinois Chicago has discovered a way to restore memory loss from Alzheimer’s disease in mice by boosting the production of neurons, the basic cells of the brain.

According to recent research, the protein CHIP can control the insulin receptor more effectively while acting alone than when in a paired state. In cellular stress situations, CHIP often appears as a homodimer – an association of two identical proteins – and mainly functions to destroy misfolded and defective proteins. CHIP thus cleanses the cell. In order to do this, CHIP works with helper proteins to bind a chain of the small protein ubiquitin to misfolded proteins.
As a result, the cell detects and gets rid of defective proteins. Furthermore, CHIP controls insulin receptor signal transduction. CHIP binds to the receptor and degrades it, preventing the activation of life-extending gene products.
Researchers from the University of Cologne have now shown via tests using human cells and the nematode Caenorhabditis elegans that CHIP can also label itself with ubiquitin, preventing the formation of its dimer. The CHIP monomer regulates insulin signaling more effectively than the CHIP dimer. The research was conducted by the University of Cologne’s Cluster of Excellence for Cellular Stress Responses in Aging-Associated Diseases (CECAD) and was recently published in the journal Molecular Cell.
After two decades of research, scientists at Technion-Israel Institute of Technology have found a way of rejuvenating human skin and organs.

Using gene modification techniques, a team of researchers have come up with a new treatment for balding, Wired reports — a condition experienced to varying degrees by two-thirds of American men by age 35.
The team, associated with the University of California, Irvine and a biotech company called Amplifica, believes they’ve identified the signaling pathway that drive hair growth to find new ways to stop stem cells from giving up on producing hair follicles.
Experiments with mice, as detailed in a new paper published in the journal Developmental Cell last month, have been promising. The mice were genetically modified to have the hair growth signaling pathway turned on permanently.
Artificial Intelligence (AI) can perform preventive healthcare activities such as health screening, routine check-up and vaccination with expert-level accuracy that can turn out to be cost-effective in the long run. Yet, a new research found that individuals show less trust in preventive care interventions suggested by AI than when the same interventions are prompted by human health experts.
The researchers at Nanyang Technological University (NTU) Singapore studied 15,000 users of a health mobile application and found that emphasising the involvement of a human health expert in an AI-suggested intervention could improve its acceptance and effectiveness.
These findings suggest that the human element remains important even as the healthcare sector increasingly adopts AI to screen, diagnose and treat patients more efficiently. The findings could also contribute to the design of more effective AI-prompted preventive care interventions, said the researchers.

SINGAPORE — A new longevity clinic where the doctor will diagnose a healthy person’s biological age and then provide a customised plan to slow ageing is being set up at Alexandra Hospital and is expected to open by early next year.
It will be the first publicly funded outpatient clinic in longevity medicine in Singapore and possibly in the world, Professor Andrea Maier, the co-director of the National University Health System (NUHS) Centre for Healthy Longevity told The Straits Times at the sidelines of the centre’s opening on Wednesday.
The clinic will be manned by internal medicine specialists like Prof Maier, who is also the founding president of the International Longevity Medicine Society that was set up last month.
