Harnessing the Brain’s Immune Cells to Stave off Alzheimer’s and Other Neurodegenerative Diseases
Posted by Jose Ruben Rodriguez Fuentes in categories: biotech/medical, neuroscience
Summary: Researchers have identified a protein that could be leveraged to help microglia in the brain stave off Alzheimer’s and other neurodegenerative diseases.
Source: The Conversation.
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.

Don’t Use at Night — Common Sedative Can Increase the Risk of Heart Damage
Posted by Genevieve Klien in category: biotech/medical
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.

Infinite Patterns Appear In Numbers Described as Moving Systems

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.

The Mathematics of Consciousness (Integrated Information Theory)
Posted by Dan Breeden in categories: mathematics, neuroscience
Entry for the #3Blue1Brown Summer of Math Exposition 2022 (#SoME2)byRodrigo Coin Curvo& Alexander Maier.
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.

Japan’s ispace set to become the first private firm to launch a lunar lander on the moon
Posted by Gemechu Taye in category: space
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.

Airbus now aims to use superconductivity to decarbonize its aircraft
Posted by Gemechu Taye in categories: particle physics, transportation
It is working with CERN to push the boundaries of clean aerospace.
Airbus and CERN, the European Laboratory for Particle Physics, have joined forces to launch Airbus UpNext, a project whose aim is to evaluate how superconductivity can contribute to the decarbonization of future aircraft systems, according to a press release by the aircraft manufacturer published last week.

Men are losing their Y chromosome, and rats could show our future
Posted by Gemechu Taye in categories: existential risks, sex
What alternative sex-determining system will we adapt?
The sex of human and other mammal babies is decided by a male-determining gene on the Y chromosome. But the human Y chromosome is degenerating and may disappear in a few million years, leading to our extinction unless we evolve a new sex gene.
A new paper in Proceedings of the National Academy of Science shows how the spiny rat has evolved a new male-determining gene.
