Summary: A new study didn’t find much of a difference between healthy low-carb and low-fat diets. The people on both diets lost about the same amount of excess weight. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

Is cutting carbs or cutting fat is better? A new study published in the Journal of the American Medical Association, suggest that it may not matter much.

A team of researchers led by Christopher Gardner, a professor of medicine at the Stanford University School of Medicine, followed 609 overweight adults ages 18 to 50. The researchers put the study participants, consisting of equal numbers of men and women, on either a low-carb diet or low-fat diet for 12 months.

Summary: UCSF scientists discover a protein in young blood that rejuvenates an aging brain. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

Scientists have long been searching for the factors in young blood that give it its rejuvenating powers to drug form for widespread public use.

A team of researchers led by Saul Villeda, Ph.D., an assistant professor of anatomy at UC San Francisco discovered a brain-rejuvenating enzyme that improved memory in adult mice when restored to youthful levels. The researchers say the new protein could lead to new therapies for maintaining the healthy brain function of humans.

Parents have been stocking up on bulletproof backpacks, tracking devices and doorstops… to give children a fighting chance at surviving a gunman’s attack at school,” the N.Y. Post reports:

“BulletBlocker, a company that sells bulletproof backpacks ranging in price from $199 for a girly pink one to $490, has seen sales jump 300 percent since the Florida shooting.”

A $95 metal device called “JustinKase,” which is placed under a door and latches to the door’s jamb to prevent entry, was invented by a 17-year-old Wisconsin high school student, Justin Rivard.


Parents are taking safety from school shooters into their own hands.

Plurals are known to value compromise, he said, a byproduct of their diversity and comfort with working with peers from different backgrounds. They are also in line to be an “adaptive” generation. These cohorts tend to come right after disruptive generations that change society in significant ways, such as millennials. When adaptive groups come of age, they take the problems that were brought to light by their predecessors and try to work them out.


In their organized calls for action, the students of Marjory Stoneman Douglas High School could be defining the nation’s newest generation.

To better protect against the rise of ill-intended AI, policymakers ought to be working closely with technical specialists to be aware of potential applications of machine intelligence. Also, technical developers ought to be proactively reaching out to appropriate leaders when they understand the technology they are developing can have negative applications, the report says.


New report from 26 technology experts issues dire warning about the potential of malicious artificial intelligence.

Elon Musk has revealed his personal cryptocurrency holdings.

The billionaire CEO of SpaceX and Tesla told Twitter followers that he in fact has never purchased cryptocurrency, and only holds a small amount of Bitcoin gifted by a friend.

Not sure. I let @jack know, but it’s still going. I literally own zero cryptocurrency, apart from .25 BTC that a friend sent me many years ago.

Physicists have confirmed the existence of a new form of atomic nuclei, and the fact that it’s not symmetrical challenges the fundamental theories of physics that explain our Universe.

But that’s not as bad as it sounds, because the 2016 discovery could help scientists solve one of the biggest mysteries in theoretical physics — where is all the dark matter? — and could also explain why travelling backwards in time might actually be impossible.

“We’ve found these nuclei literally point towards a direction in space. This relates to a direction in time, proving there’s a well-defined direction in time and we will always travel from past to present,” Marcus Scheck from the University of the West of Scotland told Kenneth MacDonald at BBC News at the time.

Researchers at the University of Chicago have developed light-activated nanowires that can stimulate neurons to fire when they are exposed to light. The researchers hope that the nanowires could help in understanding complex brain circuitry, and they may also be useful in treating brain disorders.

Optogenetics, which involves genetically modifying neurons so that they are sensitive to a light stimulus, has attracted a lot of attention as a research tool and potential therapeutic approach. However, some researchers have misgivings about optogenetics, as it involves inserting a gene into cells, potentially opening the door to unforeseen effects and possibly permanently altering treated cells.

In an effort to develop an alternative, a research team at the University of Chicago has devised a new modality that can enable light activation of neurons without the need for genetic modification. Their technique involves nanowires that are so small that if they were laid side-by-side, hundreds of them would fit on the edge of a sheet of paper. Although initially designed for use in solar cells, their small size also makes them well suited to interacting with cells.
