Scientists have been rejuvenating old mice with infusions of not just the blood of younger mice, but even blood from teenage human beings — and we finally have our first clues on why this strange technique works.

Researchers have discovered an enzyme that helps rescue ageing brains from cognitive decline. So far it’s only been shown in mice, but if the same mechanisms are found in humans, it could lead to a new class of anti-ageing therapies.

Four years ago, a team of researchers led by neurobiologist Saul Villeda from the University of California, San Francisco, discovered that giving older mice infusions of blood from younger mice improved their memory and learning by improving connections in the hippocampus.

A startup working to better understand the relationship our gut has with our brain has raised another $66 million.

New York-based Kallyope raised its series B round from new investors Two Sigma Ventures and Euclidean Capital. They were joined by Polaris Partners, Illumina Ventures, Lux Capital and others that had invested in Kallyope’s $44 million series A round in 2015.

Kallyope is trying to figure out how exactly the brain interacts with the gut by mapping it out. By collecting sequencing information about cells in the gut, for example, Kallyope can better figure out how they’re connected to neurons in the brain in a series of circuits. Understanding that relationship could lead to pills that could interact with the gut’s signals and in turn pass that message along to the brain.

Neuroscientists have devised a new method of “mind-reading” technology that recreates images perceived by the human brain based on EEG readings.

A study of the unusual digestive system of an ancient group of insects has provided new insights into future biofuel production.

Caloric restriction has long been known to increase the lifespan and healthspan of most studied animals. Research also shows that animals given a calorie-restricted diet are also generally more able to regenerate tissue damage following injury.

Caloric restriction improves tissue regeneration

A new study by the Lengner lab at the University of Pennsylvania has identified the actual cells responsible for this increased regenerative capacity in intestinal tissue[1]. The researchers found that when a mouse given a calorie-restricted diet is exposed to radiation, a specialized type of stem cell known as a reserve stem cell is able to survive and rapidly repair intestinal tissues.

I’m excited to share a new article of mine via The Daily Dot on the future of so-called “gun control,” one that promises freedom and protects people from criminals and mass shooters. As usual, the answer is in technology to improve the world—and not in Congress changing or creating laws. This is a policy article of mine, and this is the technology you could expect to see in California if I was elected Governor:

High-tech drones and surveillance technology can offer a radically new type of gun control, helping detect possible the presence of guns and intervene in mass shootings.

ASTEROID mining may sound like science fiction – but one astronomer believes it is getting closer to becoming a reality.
