Delivering right on the spot … in the brain
Posted by Roman Mednitzer in categories: biotech/medical, robotics/AI
We are making good progress in identifying neural circuits in our brain, small areas responsible for the execution of specific tasks. It is not always the case, actually several tasks are involving many areas in different regions of the brain. Also in this case, however, specific regions host neural circuits whose activity spread around influencing other neural networks. The malfunctioning of these “networks” results in disabilities and the good news is that researchers are starting to find ways to restore (in some cases) the correct working of these neural circuits using drugs.
The problem, however, is that these drugs cannot be delivered through the blood vessels since they would reach “the whole brain” and what is good for a “faulty” circuit may be bad for a “good” circuit. Besides, many drugs cannot flow across the membrane separating the arteries and veins from the brain (the so called blood-brain barrier). This obstacle is exploited by new technologies based on ultrasound beams that can be focussed in a specific place of the brain resulting in the opening of the blood vessels membrane in that area thus letting the drug reach the neurones. This is great but in mot cases it is not enough because the area “flooded” by the drug is still quite large (on a neuronal scale).

Most Americans See Artificial Intelligence as a Threat to Jobs (Just Not Theirs)
Posted by Derick Lee in categories: employment, robotics/AI
The vast majority of Americans expect artificial intelligence to lead to job losses in the coming decade, but few see it coming for their own position.
The other findings, released in January, show that more than three in four Americans believe that artificial intelligence will fundamentally change how the public works and lives in the coming decade.
A new study reveals how widely Americans use and welcome technologies featuring artificial intelligence.

Australia Is Set to Become The First Country to Completely Eliminate One Type of Cancer
Posted by Shane Hinshaw in category: biotech/medical
The International Papillomavirus Society has announced that Australia could become the first country to eliminate cervical cancer entirely.
According to a new study, Australia’s efforts to distribute a human papillomavirus (HPV) vaccine for free in schools have been a resounding success.
The sexually transmitted infection causes 99.9 percent of cases of cervical cancer.

Air Force Tech Can Hit With the Impact of a Nuclear Weapon With No Fallout
Posted by Shane Hinshaw in category: military
Unlike traditional chemical explosives, kinetic weapons need only speed and mass to do damage. These weapons have evolved significantly since the 1950s.

Engineers develop eco-friendly smart glass panels that switch from transparent to opaque
Posted by Shane Hinshaw in category: innovation
Someday we won’t need curtains or blinds on our windows, and we will be able to block out light—or let it in—with just the press of a button. At least that’s what Keith Goossen, associate professor of electrical and computer engineering at the University of Delaware, hopes.
Goossen and Daniel Wolfe, who earned a doctoral degree from UD last year, developed panels that can switch between allowing light in and blocking it out. This “smart glass” technology could be utilized in eco-friendly windows, windshields, roof panes and building envelopes, absorbing light and heat in the winter and reflecting it away in the summer.
Although Goossen isn’t the first scientist to make smart glass, his team’s invention is about one-tenth the price of other versions. It is also more transparent in its transparent state and more reflective in its reflective state than competitors, he said.

Suicide Gene Therapy Works to Kill Cancer Cells
Posted by Steve Hill in categories: biotech/medical, genetics, life extension
Some cancer cells express some of the same genes that senescent cells do, so it makes sense that drugs that destroy senescent cells may also destroy cancer cells. This was what the researchers in this new study set out to test.
However, in this experiment, the researchers discovered that the chosen senolytic drugs were not effective at destroying cancer cells with senescence-associated gene expression. While cancer cells and senescent cells do share some common properties, they are also quite different at an epigenetic level.
The researchers did, however, demonstrate that a so-called “suicide gene therapy” that causes both senescent cells and cancer cells to kill themselves worked by targeting senescence-associated p16Ink4a. This approach is similar to that of SENS spin-off company Oisin Biotechnologies, which is using a suicide gene therapy to eliminate senescent cells.

Can humans live to be 1,000 years old?
Posted by Montie Adkins in categories: futurism, life extension
And what the media and scientists think of it.
Aubrey de Grey, Ph.D., Vice President of New Technology Discovery at AgeX Therapeutics, discusses the “Methuselarity” — the point at which technology enables humans to live to more than 1,000 years of age. Dr. de Grey believes this could happen within the coming decades and posits that some people born today may live to be 1,000 years of age. He further states that people who are 30 years old today have a 50/50 chance to live to be 1,000 years old. Dr. de Grey bases his assumptions on the research into aging that companies like Agex Therapeutics are pursuing. This video is the third in a series from AgeX about the future of aging and its impact on humanity. For more information on the company, please visit www.agexinc.com.
