Nice.
This summer, more than a million tons of chardonnay grapes are plumping on manicured vineyards around the world. The grapes make one of the most popular white wines, but their juicy fruit and luscious leaves are also targets for diseases such as downy mildew, a stubborn fungus-like parasite.
The main goal of a tumour cell is, above all, to survive, even at the cost of damaging the health of the organism to which it belongs.
To do this, it is equipped with skills that healthy cells do not have, including the ability to continue surviving when glucose levels are very low.
This could be one of the reasons why widely-used anti-angiogenic agents often fail to eliminate cancer, no matter how much they starve it by hindering the development of the blood vessels that provide nutrients in general and glucose in particular.

Nice — another step forward for all things connected.
Scientists can now talk to and even command living cells–to a limited degree at the moment, but with massive implications for the future. MIT biological engineers have created a computer code that allows them to basically hijack living cells and control them. It works similarly to a translation service, using a programming language to create a function for a cell in the form of a DNA sequence. Once it’s scalable, the invention has major ramifications. Future applications could include designing cells that produce a cancer drug when a tumor is detected or creating yeast cells that halt their own fermentation if too many toxic byproducts build up.

Indeed, if we set ethical and safety objections aside, genetic enhancement has the potential to bring about significant national advantages. Even marginal increases in intelligence via gene editing could have significant effects on a nation’s economic growth. Certain genes could give some athletes an edge in intense international competitions. Other genes may have an effect on violent tendencies, suggesting genetic engineering could reduce crime rates.
We may soon be able to edit people’s DNA to cure diseases like cancer, but will this lead to designer babies? If so, bioethicist G Owen Schaefer argues that China will lead the way.

“An ultimate goal of stem cell research is to turn on the regenerative potential of one’s own stem cells for tissue and organ repair and disease therapy,” said Dr. Kang Zhang of the UC San Diego School of Medicine.
You’ll soon be able to see the future with eyes grown in petri dishes. Scientists in Japan’s Osaka University have found a new way to turn stem cells into a human eyeball in what is (needless to say) a remarkable breakthrough for the medical community. According to lead biologist Kohji Nishida, a small sample of adult skin is all that would be required in order to grow retinas, corneas, lenses, and other key components of the eye.

As reported today in the journal Nature Nanotechnology*, the IBM team’s results show size-based separation of bioparticles down to 20 nanometers (nm) in diameter, a scale that gives access to important particles such as DNA, viruses and exosomes. Once separated, these particles can be analyzed by physicians to potentially reveal signs of disease even before patients experience any physical symptoms and when the outcome from treatment is most positive. Until now, the smallest bioparticle that could be separated by size with on-chip technologies was about 50 times or larger, for example, separation of circulating tumor cells from other biological components.
IBM is collaborating with a team from the Icahn School of Medicine at Mount Sinai to continue development of this lab-on-a-chip technology and plans to test it on prostate cancer, the most common cancer in men in the U.S.
Dr. Aubrey de Grey of the of the SENS Research Foundation explains the OncoSENS approach to curing ALT-Cancer, the corresponding crowdunding campaign (https://www.lifespan.io/campaigns/sens-control-alt-delete-cancer/), and how this is a vital part of overcoming the ill-effects of aging.
This presentation is part of the Designing New Advances conference held by the Institute of Exponential Sciences in the Netherlands, orchestrated by Demian Hoed, and Lotte Van Norte.
