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.
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.
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.
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.
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.
“This whale had the most plastic we have ever seen in a whale. It’s disgusting,” museum biologists wrote in a Facebook update. “Action must be taken by the government against those who continue to treat the waterways and ocean as dumpsters.”
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 ripples may be the neural substrates through which the human brain 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 brain processes the details of our past waking experiences or episodic memories.”
The study was led by Alex P. Vaz, B.S., an M.D., Ph.D. student at Duke University, Durham, North Carolina, who was completing his dissertation work with Dr. Zaghloul. For years, Dr. Zaghloul’s team has been using grids of surgically implanted electrodes to record the electrical brain activity of drug resistant epilepsy patients enrolled in a trial at the NIH’s Clinical Center. The recordings have helped identify the source of a patient’s epileptic seizures as well as provide an opportunity to study how the brain encodes memories.
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.
Last year, the Japan Transhumanist Association, a general incorporated group that aims to promote transhumanism in Japan, used Twitter to solicit volunteers for free chip implants. More than 20,000 people applied, and 20 are currently being prepared for the procedure.
With microchip implants, humankind has taken a step toward what future-minded experts predict will be a world filled with cyborgs, but Japan lags behind other countries in this regard.
The microchips inserted under the skin are currently limited to such tasks as opening doors and paying for small items, like drinks.
However, Yuichiro Okamoto, a professor of philosophy at Tamagawa University who is well-versed on the ideological background of science and technology, says the implants are just the beginning of “transhumanism,” the theory that science can allow humans to evolve beyond their current physical and mental limitations.
