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.

Check out this week’s episode of Singularity Hub’s video series, Tech-x-planations, to learn more about what a quantum computer really is.

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.

The NASA/ESA Hubble Space Telescope caught sight of a soft, diffuse-looking galaxy that is probably the aftermath of a long-ago galactic collision. Two spiral galaxies, each perhaps much like the Milky Way, swirled together for millions of years.

In such mergers, the original galaxies are often stretched and pulled apart as they wrap around a common center of gravity. After a few back-and-forths, this starry tempest settles down into a new, round object. The now subdued celestial body, cataloged as SDSS J162702.56+432833.9, is technically known as an elliptical galaxy.

When galaxies collide—a common event in the universe—a fresh burst of star formation typically takes place as gas clouds mash together. At this point, the galaxy has a blue hue, but the color does not mean it is cold: it is a result of the intense heat of newly formed blue–white stars. Those stars do not last long, and after a few billion years the reddish hues of aging, smaller stars dominate an elliptical galaxy’s spectrum. Hubble has helped astronomers learn of this sequence by observing galaxy mergers at all stages of the process.
