First detection of sugars in meteorites gives clues to origin of life

An international team has found sugars essential to life in meteorites. The new discovery adds to the growing list of biologically important compounds that have been found in meteorites, supporting the hypothesis that chemical reactions in asteroids—the parent bodies of many meteorites—can make some of life’s ingredients. If correct, meteorite bombardment on ancient Earth may have assisted the origin of life with a supply of life’s .

The team discovered ribose and other bio-essential sugars including arabinose and xylose in two different meteorites that are rich in carbon, NWA 801 (type CR2) and Murchison (type cm2). Ribose is a crucial component of RNA (). In much of modern life, RNA serves as a messenger molecule, copying genetic instructions from the DNA molecule (deoxyribonucleic acid) and delivering them to molecular factories within the cell called ribosomes that read the RNA to build specific proteins needed to carry out life processes.

William Henry “Bill” Andrews, Ph.D. is an American molecular biologist and gerontologist whose career has centered on searching for a cure for human aging. Andrews is the founder and president of the biotechnology company Sierra Sciences. In 1997, he led the team at Geron Corporation that was the first to successfully identify human telomerase.

Artificial intelligence is ‘enhancing’ healthcare: IHDpay Group

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

Chun Yuan Chiang of IHDpay Group says artificial intelligence cannot completely replace the “high-touch” nature of medical care. However, technology can be helpful in diagnosis or in situations where patients have long, complicated medical histories, he says. Chiang was speaking on a panel with Jai Verma of Cigna International and Dai Ying of GE Healthcare.

China Killing Prisoners To Harvest Organs For Transplant: New Report Exposes Cover-Up

Posted by in category: biotech/medical

We must use the power of #Capitalism to destroy #Communist #China and their illegal organ harvesting that is killing millions of people and is a human rights violation because of #genocide. Free #HongKong, #Tibet, and #Taiwan.


China has been accused of the “state-run mass murder” of prisoners for their organs. Now the country is also accused of a systematic cover-up.

Scientists discover body’s protection shield

Posted by in categories: biotech/medical, chemistry

Scientists have discovered a way to manipulate the body’s own immune response to boost tissue repair. The findings, published in Current Biology today, reveal a new network of protective factors to shield cells against damage. This discovery, made by University of Bristol researchers, could significantly benefit patients undergoing surgery by speeding recovery times and lowering the risk of complication.

When a is damaged, (either accidentally or through surgery), the body quickly recruits to the injury site where they fight infection by engulfing and killing invading pathogens, through the release of toxic factors (such as unstable molecules containing oxygen known as “reactive oxygen species” e.g. peroxides). However, these bactericidal products are also highly toxic to the host tissue and can disrupt the repair process. To counteract these the repairing tissue activates powerful protective machinery to “shield” itself from the damage.

Now, researchers from Bristol’s School of Biochemistry studying , have mapped the exact identities of these protective pathways and identified how to stimulate this process in naïve tissues.

“Surprising” new insights into link between gut microbiome and aging

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

A new study is suggesting a metabolite produced by gut microbes could increase neuron production in the brain, improve intestinal function, and ultimately slow the aging process. Across several compelling mouse experiments the research found the negative effects of aging could be counteracted by enhanced microbial production of a molecule called butyrate.

Investigating the effect of the gut microbiome on aging, the new research first performed gut microbiome transplants between old and young mice. Using fecal transplants, young germ-free mice were colonized with the gut microbiota of older mice. The results were somewhat unexpected as the younger mice colonized with the older microbiomes displayed increased neurogenesis, a process whereby new neurons are produced in the brain.

“We’ve found that microbes collected from an old mouse have the capacity to support neural growth in a younger mouse,” explains Sven Pettersson, lead on the research team from Nanyang Technological University in Singapore. “This is a surprising and very interesting observation…”
