I wanted to focus on the animal testing portion of the Show and Tell. Neuralink representatives showed us videos of a pig that has a cortex and spinal chip in its body. It also has pin points on joints in its leg that are sending data to the Neuralink scientist. When the scientist stimulates a joint it creates an uncontrolled movement. The pig moves its leg without wanting too, but because someone else wanted it too, the pig did not want to move. That’s the focus of this video.

As the hardest tissue in the human body, enamel is not an easy material for engineers to mimic, but doing so could mean big things in materials science and regenerative medicine. Researchers are now reporting a breakthrough in this area, by tweaking the composition of a naturally occurring mineral to emulate the microstructure of natural enamel in a new type of dental coating, and do so in a way that offers even greater strength.

Carried out by scientists in Russia and Egypt, the newly developed dental coating uses hydroxyapatite as a starting point. This compound is the primary component in bone tissue and mineralized tissues in humans and animals.

The researchers doped the hydroxyapatite with a complex of amino acids that naturally aid in the repair of bone and muscle structures, such as lysine and arginine, resulting in a mineralized layer with properties resembling the main component of natural enamel. The material was then applied to healthy teeth, so the team could observe its ability to bind to real dental tissue.

The radiation from small amplitude waves on straight strings is calculated. The result is applied to a string with colliding kinks, and the power spectrum and total power obtained. The rate of rounding of the kinks due to gravitational damping is found, which enables one to show that the backreaction causes the average separation between kinks on infinite strings to scale with the horizon in an expanding universe.

Dec 26 (Reuters) — SpaceX Chief Executive Elon Musk said on Monday that the company is now close to having 100 active Starlinks, the firm’s satellite internet service, in Iran, three months after he tweeted he would activate the service there amid protests around the Islamic country.

Musk said, “approaching 100 starlinks active in Iran”, in a tweet on Monday.

The billionaire had said in September that he would activate Starlink in Iran as part of a U.S.-backed effort “to advance internet freedom and the free flow of information” to Iranians.

Trans-light speed vessels should give off gravitational waves.

This discovery confirmed a prediction made a century before by Einstein and his Theory of General Relativity and opened the door to a whole new field of astrophysical research.

A rogue company has started putting aerosols into the stratosphere because it believes it will cool the planet.

The company justifies its actions as necessary to begin to cool the planet’s atmosphere. The scientific community is in disagreement.

We all lead busy lives, and it can be hard to remember to eat healthy. Sometimes, it’s easier to just grab food off the shelf, thinking only of the convenience and not of the nutritional value. Processed foods are always on-hand, and they’ve saved us time and energy in the past. But, at what cost?

Many of the products on this list are staples of our daily diet. However, if not eaten in strict moderation (or avoided completely) they can lead to long-term health problems. Some of these products are clearly harmful, but others seem like healthy foods, only to be proven unhealthy when it’s too late. After looking at this list, you might want to reconsider what you put on your shopping list.

Jeff Lichtman is Jeremy R. Knowles Professor of Molecular and Cellular Biology at Harvard. He received an A.B. from Bowdoin (1973), and an M.D. and Ph.D. from Washington University in St. Louis (1980) where he worked for 30 years before moving to Cambridge (2004). He is a member of Harvard’s newly established Center for Brain Science. Jeff’s research interests revolve around the question of how mammalian brain circuits are physically altered by experiences, especially in early life. He has focused on the dramatic re-wiring of neural connections in early postnatal development. More recently his research has focused on developing new electron microscopy methods to map the entire wiring diagram of the developing and adult brain. One of the principal aims of this “connectomics” approach is to uncover the ways information is stored in neural networks.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
