Physicists reverse time using quantum computer

Posted by in categories: computing, law, quantum physics, space travel

Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past. They also calculated the probability that an electron in empty interstellar space will spontaneously travel back into its recent past. The study is published in Scientific Reports.

“This is one in a series of papers on the possibility of violating the . That law is closely related to the notion of the arrow of time that posits the one-way direction of time from the past to the future,” said the study’s lead author Gordey Lesovik, who heads the Laboratory of the Physics of Quantum Information Technology at MIPT.

“We began by describing a so-called local perpetual motion machine of the second kind. Then, in December, we published a paper that discusses the violation of the second law via a device called a Maxwell’s demon,” Lesovik said. “The most recent paper approaches the same problem from a third angle: We have artificially created a state that evolves in a direction opposite to that of the thermodynamic arrow of time.”

Scientists ‘Clear’ Alzheimer’s Plaque From Mice Using Only Light And Sound

Posted by in categories: biotech/medical, neuroscience

Clumps of harmful proteins that interfere with brain functions have been partially cleared in mice using nothing but light and sound.

Research led by MIT has found strobe lights and a low pitched buzz can be used to recreate brain waves lost in the disease, which in turn remove plaque and improve cognitive function in mice engineered to display Alzheimer’s-like behaviour.

It’s a little like using light and sound to trigger their own brain waves to help fight the disease.

Stanford University launches the Institute for Human-Centered Artificial Intelligence

Posted by in category: robotics/AI

Three fundamental beliefs guide Stanford’s new Institute for Human-Centered Artificial Intelligence, co-directed by John Etchemendy and Fei-Fei Li : #AI technology should be inspired by human intelligence; the development of AI must be guided by its human impact; and applications of AI should enhance and augment humans, not replace them.

The new institute will focus on guiding artificial intelligence to benefit humanity.

Water-resistant electronic skin with self-healing abilities created

Posted by in categories: biological, robotics/AI

Another step towards organic ships?

Inspired by jellyfish, researchers have created an electronic skin that is transparent, stretchable, touch-sensitive, and repairs itself in both wet and dry conditions. The novel material has wide-ranging uses, from water-resistant touch screens to soft robots aimed at mimicking biological tissues.

A Restorative Skin Cream May Reduce Inflammaging

Posted by in categories: biotech/medical, life extension

The skin is our first line of defense against invading pathogens, and scientists at UC San Francisco and the San Francisco Veterans Administration (VA) Health Care System believe that it may be a cause of inflammaging, the age-related chronic inflammation that encourages a number of age-related diseases to develop.

As we age, we generally experience a rise in this low-grade chronic inflammation, thus increasing our risk for developing a variety of age-related diseases. There are a number of proposed sources of inflammaging, including senescent cell accumulation, cell debris, immunosenescence, and increasing bacterial burden.

In a previous article, we talked about the potential role of bacterial burden in relation to the microbiota of the gut and the age-related failure of the gut membrane, which allows bacterial contamination to invade the body and increase bacterial burden and inflammation. The gut microbiota has been proposed to be an origin point of inflammaging, and researchers suggest that the skin could be another.

Dead whale found with 88 pounds of plastic in stomach in the Philippines

Posted by in categories: government, materials

Messed up is the right phrasing for it, I figure.

March 18 (UPI) — After a dead whale washed ashore in the Philippines, scientists pulled 88 pounds of plastic debris from the mammal’s intestines. The young Cuvier’s beaked whale died from gastric shock, according to biologists.

The necropsy was conducted by scientists at the D’ Bone Collector Museum. They were assigned by biologists with the Philippines Bureau of Fisheries and Aquatic Resources.

Our brains may ripple before remembering

Posted by in categories: biotech/medical, health, neuroscience

As many labs have established, Dr. Zaghloul’s team knew that our episodic memories are controlled by neurons in at least two different parts of the brain, but they did not know exactly how the cells worked together to retrieve memories. Based on a growing of body of evidence, they suspected that the short, high frequency electrical waves seen in ripples may somehow be involved. For instance, two earlier patient studies suggested that ripples may be important for solidifying memories during sleep.

A sound, a smell, a word can all flood our minds with memories of past experiences. In a study of epilepsy patients, researchers at the National Institutes of Health found that split seconds before we recall these events tiny electrical waves, called ripples, may flow through key parts of our brains that help store our memories, setting the stage for successful retrieval.

“We showed for the first time that may be the neural substrates through which the successfully recalls memories,” said Kareem Zaghloul, M.D., Ph.D., a neurosurgeon-researcher at the NIH’s National Institute of Neurological Disorders and Stroke (NINDS) and senior author of the study published in Science. “These results help us understand how the processes the details of our past waking experiences or episodic memories.”

Humans could regrow limbs as scientists uncover a ‘DNA switch’

Posted by in category: biotech/medical

It is decades away but a team in Germany did use a regenerative method on an amputees finger stumps with positive results in 2003.

Scientists from Harvard University in Massachusetts have discovered a ‘DNA switch’ that we could use to grow back parts of our bodies like animals who can regenerate, like jellyfish.
