Scientists decipher mechanisms underlying the biology of aging

Posted by in categories: bioengineering, biotech/medical, computing, life extension

Understanding the factors that control aging has been one of humanity’s endless pursuits, from the mystical fountain of youth to practical healthful regimens to prolong life expectancy.

A team of scientists at the University of California San Diego has helped decipher the dynamics that control how our cells age, and with it implications for extending human longevity. As described in a study published in the Proceedings of the National Academy of Sciences, a group led by biologist Nan Hao employed a combination of technologies in engineering, computer science and biology to analyze molecular processes that influence aging.

As cells age, damage in their DNA accumulates over time, leading to decay in normal functioning and eventually resulting in death. A natural biochemical process known as “chromatin silencing” helps protect DNA from damage. The silencing process converts specific regions of DNA from a loose, open state into a closed one, thus shielding DNA regions. Among the molecules that promote silencing is a family of proteins—broadly conserved from bacteria to humans—known as sirtuins. In recent years, chemical activators of sirtuins have received much attention and are being marketed as nutraceuticals to aid chromatin silencing in the hopes of slowing the aging process.

Liquid metal discovery ushers in new wave of chemistry and electronics

Posted by in categories: chemistry, computing, particle physics

Researchers from RMIT University in Melbourne, Australia, have used liquid metal to create two-dimensional materials no thicker than a few atoms that have never before been seen in nature.

The incredible breakthrough will not only revolutionise the way we do chemistry but could be applied to enhance data storage and make faster electronics. The “once-in-a-decade” discovery has been published in Science.

The researchers dissolve metals in to create very thin oxide layers, which previously did not exist as layered structures and which are easily peeled away.

The Future May Owe Itself to Blockchain Technology. Here’s Why

Posted by in categories: bitcoin, computing, economics, internet, satellites

Sending satellites into space is going to continue to get cheaper since SpaceX proved it could reliably launch refurbished rockets. This is going to open up space exploration to more entities allowing for the continued democratization of space. Other technological advances could make a global space centered sharing economy a real possibility.

The rise of the internet and the ubiquity of mobile computing devices have changed everything from travel and shopping to politics – think Uber, Amazon, and Twitter.
