Gut Bacteria are Important in Cancer Risk

Changes to the microbiome in the gut may explain why related conditions are linked to different risk levels and types of gastric tumors, according to a new study.

What are the microbiota and microbiome?

The microbiota is an “ecological community of commensal, symbiotic and pathogenic microorganisms” found in and on all multicellular organisms. A microbiota includes various bacteria, archaea, protists, fungi, and viruses. The microbiota has been found to be crucial for the immunologic, hormonal and metabolic balance (homeostasis) of its host.

‘Chemical surgery’ can correct genetic mutations behind many diseases – study

“Scientists are hopeful that the approach could offer new ways to understand – and even one day tackle – certain human genetic diseases by correcting mutations in a patient’s body.”

Fresh DNA base editing breakthrough brings hope of potential treatment for huge number of diseases that arise as a result of a single genetic ‘misspelling’.

Cyborgs Among Us

This film “Cyborgs Among Us” that has a segment on my #transhumanism work (as well as many others in our community) has its #Dutch premier on Nov 10 in a major international science film festival. Go see it if you can!

Imagine having a sixth sense! These are the first cyborgs that transcend the boundaries of human possibility and spark the debate about the technological evolution of mankind. Cyborgs Among Us offers insight into how technology can become part of us and the social and ethical implications associated with it.

Professor Wouter Serdijn from Delft University of Technology explains technology and the human body from the perspective of bioelectronics.

Trodusquemine Reverses Heart Disease in Mouse Study

Atherosclerosis is the number one killer in the world, and science is working on solutions to combat this age-related disease. A new mouse study has shown that the drug trodusquemine can melt away the accumulated arterial plaques that lead to heart attacks and strokes.

What is Atherosclerosis?

Atherosclerosis is an age-related disease in which toxic, oxidized cholesterol deposits in the bloodstream produce inflammation in arterial walls. This causes macrophages to swarm to these fatty deposits to clear up this toxic waste.

Ozone hole over Antarctica shrinks to smallest peak since 1988

Ozone is a colorless combination of three oxygen atoms. High in the atmosphere, about 7 to 25 miles above the Earth, ozone shields Earth from ultraviolet rays that cause skin cancer, crop damage and other problems.

Scientists at the United Nation a few years ago determined that without the 1987 treaty there would have been an extra 2 million skin cancer cases by 2030. They said overall the ozone layer is beginning to recover because of the phase-out of chemicals used in refrigerants and aerosol cans.

Kurzgesagt – It’s Time to Talk about Bringing Aging Under Medical Control

The folks at Kurzgesagt have created another great video about aging and thanks to them for giving us the opportunity to work with them in creating this video. If you would like to support our work check out (https://www.lifespan.io/campaigns/join-us-become-a-lifespan-hero/).

The video today discusses the near future technologies that are changing how we treat aging and could potentially bring it under medical control soon. It is important to discuss this topic now and its great to see popular channels like Kurzgesagt are keen to get involved in that dialogue.

Gene editing and beyond

The CRISPR-Cas9 system has revolutionised gene-editing, but cutting DNA isn’t all it can do. From turning gene expression on and off to fluorescently tagging particular sequences, this animation explores some of the exciting possibilities of CRISPR.

Researchers develop a gel for growing large quantities of neural stem cells

In many ways, stem cells are the divas of the biological world. On the one hand, these natural shapeshifters can transform themselves into virtually any type of cell in the body. In that regard, they hold the promise of being able to cure ills ranging from spinal cord injuries to cancers.

On the other hand, said associate professor of materials science and engineering Sarah Heilshorn, , like divas, are also mercurial and difficult to work with.

“We just don’t know how to efficiently and effectively grow massive numbers of stem and keep them in their regenerative state,” Heilshorn said. “This has prevented us from making more progress in creating therapies.”
