NK-cell function appears to be impaired during spaceflights over long durations according to a new study published this week. This means that immune systems could be broken down somewhat during the long trips NASA hopes to take with astronauts in the distant future. The research here was done by a team of researchers at the University of Arizona, the University of Houston, Louisiana State University, and NASA-Johnson Space Center.

Artificial intelligence, or AI is something we hear a lot about today. In this interview with Life.

Extension’s Michael A. Smith, MD, Kristen Willeumier, PhD, provides some insight into AI technology and its relationship with psychiatry which, along with neurology, studies and treats diseases of the brain. Dr. Smith predicts that AI will soon be an important part of how we understand and treat disease. According to Dr. Willeumier, some of that technology is now “ready for prime time.” Download this Live Foreverish podcast episode for FREE on iTunes!

Artificial intelligence is, simply, the intelligence of machines as opposed to human or animal intelligence. According to the New World Encyclopedia™, “Artificial intelligence (AI) is a branch of computer science and engineering that deals with intelligent behavior, learning, and adaptation in machines. John McCarthy coined the term to mean ‘the science and engineering of making intelligent machines.’”.

Today (Jan. 24), experts with the Bulletin of the Atomic Scientists (BAS) updated the imaginary timepiece, which measures the proximity of humanity’s destruction based on the position of the clock’s hands relative to midnight — the hour of the impending apocalypse.


The hands on the hypothetical Doomsday Clock suggest the world is still in dire risk of apocalypse.

© Getty Harvard scientists will attempt to replicate the climate-cooling effect of volcanic eruptions with a world-first solar geoengineering experiment set for early 2019.

The Stratospheric Controlled Perturbation Experiment (SCoPEx) will inject calcium carbonate particles high above the earth in an attempt to reflect some of the sun’s rays back into space.

It will likely mark the first time the controversial concept of dimming the sun — more scientifically known as stratospheric aerosol injection (SAI) — will be tested in the real world.

Ophthalmology company Kejako (Geneva, Switzerland) has developed what it calls a noninvasive “Phakorestoration” process, whereby a laser patterns the lens of the eye of a presbyopia patient to restore clear vision just at the level needed for the patient to avoid wearing eyeglasses. This Phakorestoration process is repeated at intervals spanning several years over a patient’s lifetime, prolonging glasses-free vision for as long as 20 years.


By modeling the complete optical parameters of the human eye using COMSOL Multiphysics software, a prescription for a series of noninvasive laser procedures for presbyopia patients can provide glasses-free vision for more than 20 years.
