A recent study from Tokyo Medical and Dental University found that melatonin and two of its metabolites help memories stick around in the brain and can shield mice, and potentially people, from cognitive decline. One of the easiest ways to test memory in mice is to rely on their natural tendency to examine unfamiliar objects.
If you’re one of the billions of people who have posted pictures of themselves on social media over the past decade, it may be time to rethink that behavior. New AI image-generation technology allows anyone to save a handful of photos (or video frames) of you, then train AI to create realistic fake photos that show you doing embarrassing or illegal things. Not everyone may be at risk, but everyone should know about it.
Photographs have always been subject to falsifications—first in darkrooms with scissors and paste and then via Adobe Photoshop through pixels. But it took a great deal of skill to pull off convincingly. Today, creating convincing photorealistic fakes has become almost trivial.
Once an AI model learns how to render someone, their image becomes a software plaything. The AI can create images of them in infinite quantities. And the AI model can be shared, allowing other people to create images of that person as well.
Summary: Researchers have identified a protein that could be leveraged to help microglia in the brain stave off Alzheimer’s and other neurodegenerative diseases.

Many neurodegenerative diseases, or conditions that result from the loss of function or death of brain cells, remain largely untreatable. Most available treatments target just one of the multiple processes that can lead to neurodegeneration, which may not be effective in completely addressing disease symptoms or progress, if at all.
The drug, midazolam, is often used before surgery to make a patient feel more relaxed. According to a new study, it is associated with an increased risk of heart damage when surgeries are performed at night.
According to a study conducted by researchers at the University of Colorado Anschutz Medical Campus, a popular drug that makes patients sleepy and less anxious before surgery is associated with an increased risk of heart damage when surgeries are performed at night.
The results provide further proof that a drug’s effectiveness might vary depending on the time it is administered.
Furstenberg’s Proof
Szemerédi had been examining sets that contain a “positive fraction” of all the integers. Take, for example, the set containing all multiples of 5. As you look at bigger and bigger swaths of the number line, multiples of 5 continue to appear regularly. Mathematicians say that the set containing all multiples of 5 has the fraction of a fifth of all the integers.

Robots and AI are already real products and services. But will they take our jobs? Or even take over? In this video I discuss these questions in a pragmatic fashion, as well as how we may usefully define “artificial intelligence”. Also covered are cloud AI services, and the role AI in digital transformation.

After a few minor showers, this meteor shower is ready to put on a show. The Geminids are one of the highest-volume meteor showers of the year.
The Tokyo-based company will also achieve the first Japanese lunar landing.
Tokyo-based ispace is set to become the world’s first private company to land a lunar lander on the moon this December. “ispace, inc., a global lunar exploration company, released an updated launch schedule for its Mission 1 (M1) lunar lander, now scheduled to liftoff from SLC-40 from Cape Canaveral Space Force Station no earlier than Dec. 11, 2022. The M1 lander, part of the HAKUTO-R lunar exploration program, will launch on a SpaceX Falcon 9 rocket,” said a press statement on ispace’s website.
The mission was initially scheduled to launch on November 30, but the launch date was delayed.
