Facial recognition technology is being tested by businesses and governments for everything from policing to employee timesheets. Even more granular results are on their way, promise the companies behind the technology: Automatic emotion recognition could soon help robots understand humans better, or detect road rage in car drivers.

But experts are warning that the facial-recognition algorithms that attempt to interpret facial expressions could be based on uncertain science. The claims are a part of AI Now Institute’s annual report, a nonprofit that studies the impact of AI on society. The report also includes recommendations for the regulation of AI and greater transparency in the industry.

“The problem is now AI is being applied in a lot of social contexts. Anthropology, psychology, and philosophy are all incredibly relevant, but this is not the training of people who come from a technical [computer science] background.” says Kate Crawford, co-founder of AI Now, distinguished research professor at NYU and principal researcher at Microsoft Research. “Essentially the narrowing of AI has produced a kind of guileless acceptance of particular strands of psychological literature that have been shown to be suspect.”

TMAO (trimethylamine N-oxide) — a gut bacteria byproduct formed during digestion—can lead to the development of cardiovascular disease, including heart attacks and strokes. TMAO is produced when gut bacteria digest choline, lecithin and carnitine, nutrients that are abundant in animal products such as red meat and liver and other animal products.


In concurrent studies, Cleveland Clinic researchers have uncovered new mechanisms that demonstrate why and how regularly eating red meat can increase the risk of heart disease, and the role gut bacteria play in that process.

The research, led by Stanley Hazen, M.D., Ph.D., builds upon showing TMAO (trimethylamine N-oxide) — a gut bacteria byproduct formed during digestion—can lead to the development of cardiovascular disease, including heart attacks and strokes. TMAO is produced when gut bacteria digest choline, lecithin and carnitine, nutrients that are abundant in animal products such as and liver and other animal products.

In a new dietary intervention study published today in the European Heart Journal, the researchers found that a rich in red meat as the primary protein source significantly increases circulating TMAO levels, compared to diets with white meat or non-meat as protein sources. The study showed chronic red meat consumption enhanced the production of TMAO by gut microbes and reduced the kidneys’ efficiency of expelling it. Both enhanced production and reduced elimination caused by a red meat diet contribute to elevation in TMAO levels, which has been linked to the development of atherosclerosis and heart disease complications.

Try to spot a dolphin swimming through a sea of Jovian clouds.

In a phenomenon called pareidolia, humans can find shapes in what is otherwise just random data. Is Flipper actually splashing across Jupiter’s atmosphere? Obviously not. But a new series of images that showcase a dolphin-shaped cloud moving across Jupiter’s southern belt is really enjoyable to look at.

Citizen-scientists Brian Swift and Sean Doran made the images using data from the JunoCam imager, an instrument on board NASA’s Juno spacecraft. On Oct. 29, the spacecraft performed its 16th close flyby of Jupiter.

If it’s quiet solitude and beauty you seek, there is no better place than the surface of Mars has earned its moniker as the red planet, but the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter (MRO) can transform the subtle differences of soils into a rainbow of colours.

For 10 years, HiRISE has recorded gorgeous – and scientifically valuable – images of Mars. Its photos are so detailed that scientists can examine the planet’s features at the scale of just a few feet, including the recent crash site of Europe’s Schiaparelli Mars lander.

We combed through 2,054 of the camera’s latest pictures, released in August, September, and October, to bring you some of the best – and hopefully help you temporarily escape Earth.

Of the 10 flavonoids tested, fisetin was the most potent senolytic. Acute or intermittent treatment of progeroid and old mice with fisetin reduced senescence markers in multiple tissues, consistent with a hit-and-run senolytic mechanism.


The natural product fisetin has senotherapeutic activity in mice and in human tissues. Late life intervention was sufficient to yield a potent health benefit. These characteristics suggest the feasibility to translation to human clinical studies.

Having separate neuronal correlates for appetitive and aversive behavior in our brain may explain why we are striving for ever-greater rewards while simultaneously minimizing threats and dangers. Such balanced behavior of approach-and-avoidance learning is surely helpful for surviving competition in a constantly changing environment.


Dopamine has a reputation as the key player in the brain’s reward circuits, making us seek out pleasurable experiences, but growing evidence points to a multipronged role for the neurotransmitter. In particular, dopamine may also reinforce avoidance of painful experiences. UC Berkeley researchers have now mapped dopamine neurons in the brain with fiber photometry and discovered two parallel dopamine circuits driving attractive and aversive reinforcement learning and motivation.

A number of therapies that directly target the aging processes are currently in human trials and could change medicine significantly in the next decade if the results are positive.

What is aging?

Aging is basically the accumulation of damage and errors caused by a collection of varied processes that harm the functions of the body through the accumulation of waste, imperfect repair, the deregulation of cellular processes, the dysfunction of the immune system, chronic inflammation, and other disorders.
