Magnetic Fields Encourage Cellular Reprogramming

Posted by in categories: bioengineering, biotech/medical, genetics, health

Could be used in a portable device to genetically reprogram ones body.


Environmental conditions, such as heat, acidity, and mechanical forces, can affect the behavior of cells. Some biologists have even shown that magnetic fields can influence them. Now, for the first time, an international team reports that low-strength magnetic fields may foster the reprogramming of cellular development, aiding in the transformation of adult cells into pluripotent stem cells (ACS Nano 2014, DOI: 10.1021/nn502923s). If confirmed, the phenomenon could lead to new tools for bioengineers to control cell fates and help researchers understand the potential health effects of changing magnetic fields on astronauts.

Biologists have been building up evidence that magnetic fields affect living things, says Michael Levin, director of Tufts University’s Center for Regenerative & Developmental Biology, who was not involved in the new study. For example, plants and amphibian embryos develop abnormally when shielded from Earth’s geomagnetic field. And there’s some clinical evidence that particular electromagnetic frequencies promote bone fracture healing and wound repair (Eur. Cytokine Network 2013, DOI: 10.1684/ecn.2013.0332).

Optimal quantum computation linked to gravity

Posted by in categories: computing, quantum physics

Information and gravity may seem like completely different things, but one thing they have in common is that they can both be described in the framework of geometry. Building on this connection, a new paper suggests that the rules for optimal quantum computation are set by gravity.

Physicists Paweł Caputa at Kyoto University and Javier Magan at the Instituto Balseiro, Centro Atómico de Bariloche in Argentina have published their paper on the link between and gravity in a recent issue of Physical Review Letters.

In the field of , one of the main ideas is minimizing the cost (in terms of computational resources) to solve a problem. In 2006, Michael Nielsen demonstrated that, when viewed in the context of differential geometry, computational costs can be estimated by distances. This means that minimizing computational costs is equivalent to finding minimal “geodesics,” which are the shortest possible distances between two points on a curved surface.

New Turbulence Models Could Predict Galaxy Formation

Posted by in categories: information science, space

Scientists found a way to make sense of particularly chaotic events in nature.

Thanks to a new set of equations for modeling turbulence, scientists can now better predict things like how galaxies form in distant space, complex weather patterns here on Earth, and nuclear fusion. According to the research, published this Spring in the journal Physical Review Letters, turbulence may start out chaotic but then falls into a more uniform pattern that scientists can readily model and understand.

Artificially Created Tiny Human Brains Show Signs of Neural Activity

Posted by in category: neuroscience

All human experience is rooted in the brain, but we just barely understand how it works. That’s partially because it’s hard to study: Scientists can’t just run experiments on living brains, and experiments on animal brains don’t always translate to humans. That’s why researchers developed the brain organoid, an artificially grown, three-dimensional cluster of human neurons that faithfully mimics brain development — and, as Japanese scientists reported Wednesday in Cell Stem Cell, the neural activity of a living brain as well.

Neurons in a living brain respond to stimuli by “firing” off electrical impulses, which they use to communicate with one another and with other parts of the body. The scientists behind the new paper discovered that the brain organoids they grew from scratch in their lab also started to exhibit synchronized activity, just like neurons in an actual brain. That team included first and co-corresponding author Hideya Sakaguchi, Ph.D., a postdoctoral fellow at Kyoto University currently at the Salk Institute.

“I was very excited to see some of the neurons activated at the same time robustly at first,” Sakaguchi, who did the first of his experiments in December 2016, tells Inverse. “Neurons first show individual activities, but as they form networks and connections between other neurons, they start to show synchronized activities.”

‘Mystical’ psychedelic compound found in normal brains

the trouble comes when UBI is used as a way of merely making techno-capitalism more tolerable for…

Posted by in categories: business, economics, Elon Musk

So, if something is universal, doesn’t it mean that it will apply to everybody? If so, why are individual countries racing to experiment with UBI? (Sam Altman, chairman of Y Combinator and co-chairman of OpenAI, may be the exception to date but he is attempting that in a silo).

To truly address the root causes of exploitation and inequality, why isn’t the paradigm of ‘I win, you lose’ Nonsense surfaced? Is that because you are so preoccupied with surviving/getting ahead for yourself, you are not aware Business-as-usual is the water we swim in?

Most countries don’t even have a minimum wage but Silicon Valley technocrats like Bill Gate, Mark Zuckerberg, Elon Musk and others globally are universal basic income (UBI) advocates. To expedite the latest Business-as-usual gold rush, UBI could be an initial bait.

Material Could Help Storm-Proof Future Buildings

Posted by in categories: climatology, materials

A formerly little-known molecule created in labs by scientists could help future buildings withstand even the most ferocious of storms, tornadoes, and hurricanes by making walls that are virtually indestructible, according to new research from a team of British scientists at the University of Exeter.

The substance is known to researchers and construction experts as graphene, a combination of the prefix graphite and the suffix –ene, coined by the German scientist who pioneered it. The product has a wide array of potential applications including anti-corrosive coatings, lubricants, and motor oils. But in the last two decades, a radical new application has become apparent to those who study this innovative new product. The application of graphene in construction became apparent when researchers established that the inclusion of graphene oxide significantly increases both tensile and compressive strength in concrete composites—in other words, the world’s most common construction material can be fortified to become a kind of “super-concrete.”
