In a study published Jan. 1 in Nature, researchers from Google Health, and from universities in the U.S. and U.K., report on an AI model that reads mammograms with fewer false positives and false negatives than human experts. The algorithm, based on mammograms taken from more than 76,000 women in the U.K. and more than 15,000 in the U.S., reduced false positive rates by nearly 6% in the U.S., where women are screened every one to two years, and by 1.2% in the U.K., where women are screened every three years. The AI model also lowered false negatives by more than 9% in the U.S. and by nearly 3% in the U.K.


Working with medical experts, engineers at Google Health have created an AI model that lowers false positive and false negative rates for mammogram breast cancer screening.

There may be as many as 80,000 American prisoners currently locked-up in a SHU, or segregated housing unit. Solitary confinement in a SHU can cause irreversible psychological effects in as little as 15 days. Here’s what social isolation does to your brain, and why it should be considered torture.

There’s no universal definition for solitary confinement, but the United Nations describes it as any regime where an inmate is held in isolation from others, except guards, for at least 22 hours a day. Some jurisdictions allow prisoners out of their cells for one hour of solitary exercise each day. But meaningful contact with others is typically reduced to a bare minimum. Prisoners are also intentionally deprived of stimulus; available stimuli and the fleetingly rare social contacts are rarely chosen by the prisoners, and are are typically monotonous and inconsiderate of their needs.

“A hormone that is released during exercise may improve brain health and lessen the damage and memory loss that occur during dementia, a new study finds. The study, which was published this month in Nature Medicine, involved mice, but its findings could help to explain how, at a molecular level, exercise protects our brains and possibly preserves memory and thinking skills, even in people whose pasts are fading.”


Exercise doesn’t just strengthen your muscles, it can also be good for your mind and memory. Fitness advice from the year in Well.

When it comes to kefir benefits, there are more than you can shake a well populated gut microbiome at. Because the drink – typically made from cow, goat or sheep milk, that gets the funky, fermented treatment – is resplendent in potential wins for your health.

But it can be a bit of a, erm, challenging concept. Why? Well, the texture can wind up somewhat lumpy, and the taste is distinctly sour. It’s fermented by adding kefir grains, which are colonies of yeast and lactic acid bacteria that look like tiny gel-like beads, similar to those used for sourdough, to milk and leaving for 24 hours, allowing the microorganisms to multiply and ferment the lactose to lactic acid. Bang: you’ve got DIY kefir.

Though — shocker — is isn’t vegan, it is possible to make from non-dairy milks or drinks, like coconut water, but the benefits proven in the same way. It is however low in lactose (the natural sugar in the milk), as the process of making kefir turns the lactose into lactic acid, so often lactose intolerant people can drink it.

Has anybody else notice the light spectrum in new imaging. Color equals light frequency. This should be a major study. This vid is just for the color imagings reference.


In this informative talk about brain health, Dr. Daniel G. Amen makes a powerful case for preventative living through healthy habits. In a time where bodies are expanding and brains are shrinking, he calls this game-changing lifestyle The Brain Warrior’s Way.

The plan focuses on diet and exercise and delivers results in not only physical but also scientific proof. In a series of images, Amen shows several shrunken brains that with a proper lifestyle, expand to a healthier mass in a matter of months.

This is the fourth instalment in a four-part series examining the brewing US-China war over the development and deployment of artificial intelligence technology.

China has had success with AI and surveillance, but when it comes to social issues such as education, health care and agriculture, there is still a ways to go.


China has had success with private sector AI, but when it comes to social issues such as education, health care and agriculture, there is still some way to go to reach its goals.

Mice fed a plant-rich diet are less susceptible to gastrointestinal (GI) infection from a pathogen such as the one currently under investigation for a widespread E. coli outbreak tied to romaine lettuce, UT Southwestern researchers report. A strain of E. coli known as EHEC, which causes debilitating and potentially deadly inflammation in the colon with symptoms such as bloody diarrhea and vomiting, is implicated in several foodborne outbreaks worldwide each year.

“There has been a lot of hearsay about whether a plant-based diet is better for intestinal health than a typical Western diet, which is higher in oils and protein but relatively low in fruits and vegetables,” says Vanessa Sperandio, Ph.D., professor of microbiology and biochemistry at UT Southwestern. “So we decided to test it.”

Her study on a mouse model of EHEC is published this week in Nature Microbiology.
