Facebook funds AI mind-reading experiment
Facebook has announced a breakthrough in its plan to create a device that allows people to type just by thinking.
It has funded a study that developed machine-learning algorithms capable of turning brain activity into speech
It worked on epilepsy patients who had already had recording electrodes placed on their brains to asses the origins of their seizures, ahead of surgery.
Amputee can feel objects again with prosthetic arm inspired by Luke Skywalker
About 17 years ago, Keven Walgamott lost his left hand and part of his forearm in an electrical accident. Now, Walgamott can use his thoughts to tell the fingers of his bionic hand to pick up eggs and grapes. The prosthetic arm he tested also allowed Walgamott to feel the objects he grasped.
A biomedical engineering team at the University of Utah created the “LUKE Arm,” named in honor of the robotic hand Luke Skywalker obtains in “Star Wars: The Empire Strikes Back” after Darth Vader slices off his hand with a lightsaber.
A new study published Wednesday in the journal Science Robotics explained how the arm revived the sensation of touch for Walgamott. The University of Chicago and the Cleveland Clinic were also involved in the study.
Jeffrey Epstein Hoped to Seed Human Race With His DNA
Mr. Epstein’s vision reflected his longstanding fascination with what has become known as transhumanism: the science of improving the human population through technologies like genetic engineering and artificial intelligence. Critics have likened transhumanism to a modern-day version of eugenics, the discredited field of improving the human race through controlled breeding.
Mr. Epstein, the accused sex trafficker, was fascinated by eugenics. He told scientists and others of his vision of using his New Mexico ranch to impregnate women.

New ‘don’t eat me’ signal may provide basis for cancer therapies
Researchers at the Stanford University School of Medicine have discovered a new signal that cancers seem to use to evade detection and destruction by the immune system.
The scientists have shown that blocking this signal in mice implanted with human cancers allows immune cells to attack the cancers. Blocking other “don’t eat me” signals has become the basis for other possible anti–cancer therapies.
Normally, immune cells called macrophages will detect cancer cells, then engulf and devour them. In recent years, researchers have discovered that proteins on the cell surface can tell macrophages not to eat and destroy them. This can be useful to help normal cells keep the immune system from attacking them, but cancer cells use these “don’t eat me” signals to hide from the immune system.
Glowing cholesterol helps scientists fight heart disease
A newly developed technique that shows artery clogging fat-and-protein complexes in live fish gave investigators from Carnegie, Johns Hopkins University, and the Mayo Clinic a glimpse of how to study heart disease in action. Their research, which is currently being used to find new drugs to fight cardiovascular disease, is now published in Nature Communications.
Fat molecules, also called lipids, such as cholesterol and triglycerides are shuttled around the circulatory system by a protein called Apolipoprotein-B, or ApoB for short. These complexes of lipid and protein are called lipoproteins but may be more commonly known as “bad cholesterol.”
Sometimes this fat-and-cholesterol ferrying apparatus stops in its tracks and embeds itself in the sides of blood vessels, forming a dangerous buildup. Called plaque, these deposits stiffen the wall of an artery and makes it more difficult for the heart to pump blood, which can eventually lead to a heart attack.
