Study shows extra virgin olive oil staves off multiple forms of dementia in mice

Posted by in categories: biotech/medical, life extension, neuroscience

Boosting brain function is key to staving off the effects of aging. And if there was one thing every person should consider doing right now to keep their brain young, it is to add extra virgin olive oil (EVOO) to their diet, according to research by scientists at the Lewis Katz School of Medicine at Temple University (LKSOM). EVOO is a superfood, rich in cell-protecting antioxidants and known for its multiple health benefits, including helping put the brakes on diseases linked to aging, most notably cardiovascular disease. Previous LKSOM research on mice also showed that EVOO preserves memory and protects the brain against Alzheimer’s disease.

In a new study in mice published online in the journal Aging Cell, LKSOM scientists show that yet another group of aging-related diseases can be added to that list—tauopathies, which are characterized by the gradual buildup of an abnormal form of a protein called tau in the . This process leads to a decline in mental function, or dementia. The findings are the first to suggest that EVOO can defend against a specific type of mental decline linked to tauopathy known as frontotemporal dementia.

Alzheimer’s disease is itself one form of dementia. It primarily affects the hippocampus—the memory storage center in the brain. Frontotemporal dementia affects the areas of the brain near the forehead and ears. Symptoms typically emerge between ages 40 and 65 and include changes in personality and behavior, difficulties with language and writing, and eventual deterioration of memory and ability to learn from prior experience.

No, CBD isn’t right for everyone: CBD myths Canadians need to know

Posted by in category: biotech/medical

According to the World Health Organization, CBD “is generally well-tolerated with a good safety profile,” but it’s not for everyone. CBD or cannabis-derived medicines can have contraindications with other drugs and can have side effects. A 2017 review of CBD studies said the most commonly reported are fatigue, diarrhea, and appetite or weight changes.


CBD is often touted as a cure-all, but that’s not the whole story. Learn everything you need to know about how CBD works—and how it doesn’t—here.

Ralph Merkle on Space Cryonics & Nanotechnology

Posted by in categories: biotech/medical, cryonics, nanotechnology, space travel

Alcor calls them “patients”, and right now, over 150 of these frozen souls are waiting for the future in vats of liquid nitrogen stored in Scottsdale, Arizona. We interview Dr. Ralph Merkle, a director at the Alcor Foundation and a respected pioneer in nanotechnology, to learn how recent advances in cryonics just may enable long-haul interstellar spaceflight sooner than you’d guess…

US Military scientists create plan for future ‘cyborg super soldier’

Posted by in categories: cyborgs, military

Future armies could be made up of half-human half-machine cyborgs with infrared sight, ultrasonic hearing and super strength, equipped with mind-controlled weapons.

In a US Army report, experts from Devcom — the Combat Capabilities Development Command — outlined a number of possible future technologies that could be used to enhance soldiers on the battlefield by 2050.

This is how Facebook’s AI looks for bad stuff

Posted by in categories: robotics/AI, terrorism

The context: The vast majority of Facebook’s moderation is now done automatically by the company’s machine-learning systems, reducing the amount of harrowing content its moderators have to review. In its latest community standards enforcement report, published earlier this month, the company claimed that 98% of terrorist videos and photos are removed before anyone has the chance to see them, let alone report them.

So, what are we seeing here?: The company has been training its machine-learning systems to identify and label objects in videos—from the mundane, such as vases or people—to the dangerous, such as guns or knives. Facebook’s AI uses two main approaches to look for dangerous content. One is to employ neural networks that look for features and behaviors of known objects and label them with varying percentages of confidence (as we can see in the video, above.)

Training in progress: These neural networks are trained on a combination of pre-labelled videos from its human reviewers, reports from users, and soon, from videos taken by London’s Metropolitan Police. The neural nets are able to use this information to guess what the entire scene might be showing, and whether it contains any behavior or images that should be flagged. It gave more details on how its systems work at a press briefing this week.

Ecology for Insiders

Posted by in category: materials

The view from the HazeCam, which is situated just west of the Jackson Street Bridge in Newark, New Jersey, usually extends for about eight miles. To the east, the skyline of New York City rises and falls along the horizon like a bar graph, buffered by a blue haze of humidity and particulate emissions and ozone. The towers are planted into the rock of Manhattan, and the island of steel-and-concrete canyons covers 59 square kilometers and accommodates 1.5 million people. Techni…


The indoor biome covers as much as six percent of the world’s landmass—and we know almost nothing about it.

The tone of voice varies when cells communicate

Posted by in category: futurism

How cells communicate is the focus of a new thesis from the University of Gothenburg.

“By studying mammalian , as well as fruit fly nerve cells, we’ve improved our understanding of how cells communicate,” says thesis author Anna Larsson.

In order to survive, the cells in our body need to be able to communicate with each other. One way for them to “talk to each other” is to send a from one cell to another by secreting molecules. The recipient cell interprets the message and can adapt depending on the meaning of the signal.
