Thieves are now using AI deepfakes to trick companies into sending them money

Posted by in categories: economics, finance, law, robotics/AI

That might explain things…


There may soon be serious financial and legal ramifications to the proliferation of deepfake technology. The Wall Street Journal reported last week that a UK energy company’s chief executive was tricked into wiring €200,000 to a Hungarian supplier because he believed his boss was instructing him to do so. Instead, it was a thief using deepfake tech.

Researchers Teleport Information Between Two Computer Chips for the First Time

Posted by in categories: computing, internet, nanotechnology, particle physics, quantum physics

For the first time, researchers and scientists from the University of Bristol, in collaboration with the Technical University of Denmark (DTU), have achieved quantum teleportation between two computer chips. The team successfully developed chip-scale devices that are able to harness the applications of quantum physics by generating and manipulating single particles of light within programmable nano-scale circuits.

Unlike regular or science fiction teleportation which transfer particles from one place to another, with quantum teleportation, nothing physical is being transported. Rather, the information necessary to prepare a target system in the same quantum state as the source system is transmitted from one location to another, with the help of classical communication and previously shared quantum entanglement between the sending and receiving location.

In a feat that opens the door for quantum computers and quantum internet, the team managed to send information from one chip to another instantly without them being physically or electronically connected. Their work, published in the journal Nature Physics, contains a range of other quantum demonstrations. This chip-to-chip quantum teleportation was made possible by a phenomenon called quantum entanglement. The entanglement happens between two photons (two light particles) with the interaction taking place for a brief moment and the two photons sharing physical states. Quantum entanglement phenomenon is so strange that physicist Albert Einstein famously described it as ‘spooky action at a distance’.

The time paradox: How your brain creates the fourth dimension

We all feel the passing of time, but nothing in physics suggests it is a fundamental property of the universe. So where does our sense of time’s flow come from?

This Powder—Not Gas—Could Rescue Nuclear Fusion

Posted by in category: nuclear energy

Researchers at Princeton University have found a way to make a tokamak nuclear fusion reactor safer using insulating boron powder. The new research appears in the IAEA journal Nuclear Fusion and comes from Princeton’s U.S. Department of Energy-funded Princeton Plasma Physics Laboratory (PPPL).

A tokamak, like the huge one that will reach 200 million Celsius in China next year, is a nuclear fusion plasma reactor where extremely hot, charged plasma spins and generates virtually limitless energy. The Princeton research examines the way boron powder can prevent one of the fundamental flaws in existing plasma reactor technology.

Space Debris Is Now a Big Problem | VICE on HBO

Posted by in categories: military, satellites

More than half a million pieces of man-made space junk are orbiting the Earth at speeds up to 17,500 miles per hour. Even the tiniest pieces have the potential to destroy any of the 1,700 satellites circling the Earth.

Nuclear physicist Taylor Wilson joined the Air Force Space Command to see how a growing military and commercial space presence threatens the ubiquitous satellites, which are essential to humanity’s digital way of life.

Stangle: Impossible burgers are made of what?

Engineering Food: The Impossible Whopper.

“Now, let’s compare the estrogen hormone in an impossible whopper to the whopper made from hormone implanted beef. The impossible whopper has 44 mg of estrogen and the whopper has 2.5 ng of estrogen. Now let me refresh your metric system. There are 1 million nanograms (ng) in one milligram (mg). That means an impossible whopper has 18 million times as much estrogen as a regular whopper. Just six glasses of soy milk per day has enough estrogen to grow boobs on a male. That’s the equivalent of eating four impossible whoppers per day. You would have to eat 880 pounds of beef from an implanted steer to equal the amount of estrogen in one birth control pill.”


The impossible whopper is being advertised by Burger King as a plant based alternative to the whopper. When food manufacturers started talking about making artificial meat, I, too, thought it would be impossible to make a hamburger cheaply enough to make it competitive. You see, I assumed that they would have to buy the individual amino acids (the building blocks for protein) and chemically string them together in the proper order, then remove the reagents (chemicals needed to cause the chain reactions) and then add something to give it the right textures.

Injection of virus-delivered gene silencer blocks ALS degeneration, saves motor function

Posted by in categories: biotech/medical, life extension, neuroscience

Writing in Nature Medicine, an international team headed by researchers at University of California San Diego School of Medicine describe a new way to effectively deliver a gene-silencing vector to adult amyotrophic lateral sclerosis (ALS) mice, resulting in long-term suppression of the degenerative motor neuron disorder if treatment vector is delivered prior to disease onset, and blockage of disease progression in adult animals if treatment is initiated when symptoms have already appeared.

The findings are published in the December 23, 2019 online issue of the journal Nature Medicine. Martin Marsala, MD, professor in the Department of Anesthesiology at UC San Diego School of Medicine and a member of the Sanford Consortium for Regenerative Medicine, is senior author of the study.

ALS is a neurodegenerative that affects nerve cells in the brain and . Motor neurons responsible for communicating movement are specifically harmed, with subsequent, progressive loss of muscle control affecting the ability to speak, eat, move and breathe. More than 5,000 Americans are diagnosed with ALS each year, with an estimated 30,000 persons currently living with the disease. While there are symptomatic treatments for ALS, there is currently no cure. The majority of patients succumb to the disease two to five years after diagnosis.
