Future of Virtual Reality Series Launches Today

Posted by in categories: neuroscience, space, space travel, virtual reality

If you’ve ever watched someone experience virtual reality for the first time, you know it can involve screaming, flapping arms, and occasional falls.

On one level people know their bodies are safe on the stable chair, but as their minds are catapulted through outer space on a spaceship to Mars or beamed into a refugee camp in Syria —they can’t help but lose their grip on reality and go along for the ride.

In fact, our brains don’t even require photorealism for suspension of disbelief in VR. A choppy CGI rendition will cause our heart rates to increase and our palms to get sweaty when we’re riding a virtual roller coaster or standing on the edge of a virtual building looking at the ground 30 stories below.

A Possible Way to Cure Baldness

Posted by in category: biotech/medical

Meanwhile there is something important going on in the fight against baldness.

As in the majority of tissues, the hair follicle has stem cells. There are two types of stem cells that are responsible for the continuous renewal of the follicles. The first type is called active stem cells and they start dividing quite easily. Stem cells of the second type are called quiescent and in case of the new hair growth they don’t start dividing as easily. At the same time, the new hair is based primarily on quiescent cells, which attracted close attention of researchers to these cells. At first people thought that baldness was due to this type of cells.

However, recent studies showed that bald men did have those quiescent cells in their follicles. The problem was that they didn’t divide at all and didn’t contribute to forming new hairs.

Mystery Deepens: Matter and Antimatter Are Mirror Images

Posted by in category: particle physics

Matter and antimatter appear to be perfect mirror images of each other as far as anyone can see, scientists have discovered with unprecedented precision, foiling hope of solving the mystery as to why there is far more matter than antimatter in the universe.

Everyday matter is made up of protons, neutrons or electrons. These particles have counterparts known as antiparticles — antiprotons, antineutrons and positrons, respectively — that have the same mass but the opposite electric charge. (Although neutrons and antineutrons are both neutrally charged, they are each made of particles known as quarks that possess fractional electrical charges, and the charges of these quarks are equal and opposite to one another in neutrons and antineutrons.)

The known universe is composed of everyday matter. The profound mystery is, why the universe is not made up of equal parts antimatter, since the Big Bang that is thought to have created the universe 13.7 billion years ago produced equal amounts of both. And if matter and antimatter appear to be mirror images of each other in every respect save their electrical charge, there might not be much any of either type of matter left — matter and antimatter annihilate when they encounter each other.

Apple’s electric car is real, and it’s almost ready for testing

Posted by in category: transportation

Apple is definitely working on a self-driving car project, and according to some new documents, Project Titan appears to be further along than anyone thought.

Rumors of Apple’s car project first starting surfacing at the beginning of this year, with an announcement not expected until 2020 at the earliest, but the Guardian reports that Apple is already trying to secure a super-secret Bay Area test facility for the electric car.

Antioxidants: Separating Myth From Reality

Posted by in categories: health, life extension

Ever since the free radical theory of aging was conceived in the 1950s, antioxidants have been a buzzword in health — saturating the cosmetic industry and contributing to a smoothie blending, supplement popping boom.


Ever since the free radical theory of aging was conceived in the 1950s, antioxidants have been a buzz word in health — saturating the cosmetic industry and contributing to a smoothie blending, supplement popping boom. While antioxidants can certainly play an essential role in health, there is growing evidence that additional supplementation has limited benefit and can actually be harmful in some cases.

Aging has yet to be ascribed to one, singular cause and the free radical theory has struggled to prove itself. While in some organisms reducing oxidative stress can prove beneficial and increasing mitochondria targeted catalase (an important antioxidant enzyme) production in mice showed a modest increase in lifespan, when important enzymes were knocked out in C. elegans (a model organism) there was curiously no reduction and reducing expression of various antioxidant mechanisms in mice also failed to reduce lifespan. While a certain amount of vitamins and antioxidant intake is necessary, as many are co-factors in essential reactions, it seems that aside from nutritional value there is little consensus regarding additional benefits.
