Quantum Physics is Bringing Our Wildest Sci-Fi Dreams to Life
Posted by Shane Hinshaw in categories: biotech/medical, quantum physics
Quantum physics is one of the most exciting and innovative areas of scientific research. By funding further research and development in quantum physics, great technological advancements will be made.
Think of every amazing future technology you’ve seen or read about in science fiction, or imagined yourself. Big innovations that change the world and cure disease or end war, and littler ones too, things that help us “think” a quick message to a friend without saying a word or share an experience from a distance. Quantum physics is enabling the creation of all of these futuristic technologies and some that didn’t even occur to most of us, making our sci-fi dreams part of our reality.

Customized babies are closer than you think

The race is on to edit genes and prevent disease. But this technology is ripe for abuse.
Economic inequity already exists in the reproductive industry. IVF, for example, is not covered by insurance in most states (Massachusetts excepted), setting up a situation in which only infertile people with well-padded pockets can afford the treatment. And of course the well-off have easier access to good health care via quality private insurance — or their own bank accounts. Steve Jobs, for example, spent $100,000 in 2011 to sequence his genome and that of his pancreatic tumor — a bill not many could hope to afford.
“The beautiful thing about this [gene-editing] work is it offers an opportunity to intervene around the moment of birth,” says Katy Kozhimannil, an associate professor in the Division of Health Policy at University of Minnesota’s School of Public Health. “That said, as we pay attention to the opportunity of that moment, it’s important to bear in mind the value of liberty and justice for all.”

Scientists Hack a Human Cell and Reprogram It Like a Computer
Posted by Shailesh Prasad in categories: biotech/medical, computing
New research shows that cells understand and execute directions correctly, and scientists may be able to take advantage.
By hijacking the DNA of a human cell, they showed it’s possible to program it like a simple computer.

Neuroscientists Have Accidentally Discovered a Whole New Role for the Cerebellum
Posted by Shailesh Prasad in categories: biotech/medical, computing, neuroscience
One of the best-known regions of the brain, the cerebellum accounts for just 10 percent of the organ’s total volume, but contains more than 50 percent of its neurons.
Despite all that processing power, it’s been assumed that the cerebellum functions largely outside the realm of conscious awareness, instead coordinating physical activities like standing and breathing. But now neuroscientists have discovered that it plays an important role in the reward response — one of the main drives that motivate and shape human behaviour.
Not only does this open up new research possibilities for the little region that has for centuries been primarily linked motor skills and sensory input, but it suggests that the neurons that make up much of the cerebellum — called granule cells — are functioning in ways we never anticipated.

How to avoid the adverse reactions of senolytics through better design
Posted by Montie Adkins in categories: biotech/medical, life extension
Another biomarker of senescent cells could be p16, a protein whose levels increase when cells stop dividing if old and also a protein whose gene is turned off in many human cancers.
Coming back to our topic – designing senolytics that avoid the apoptosis of young, healthy cells – the ideal senolytic should accomplish two things: –turn on p53 at increased levels to determine stubborn, senescent cells to commit suicide –do that on senescent cells only.
And in order to accomplish the second part, such a drug should be ‘programmed’ to only act on those cells where it recognizes senescence-associated biomarkers. There is no single biomarker today that stains positive or negative on all types of senescence cells, but increased levels of beta-galactosidase and p16 proteins could be a welcome start to identify old cells in vivo when designing such a drug.
