Genomics and lab studies reveal numerous new findings about Alzheimer’s disease, including a key role for Reelin amid neuronal vulnerability, and for choline and antioxidants in sustaining cognition.
I remember hearing about this in one of the programs in discovery science. The physicist claimed that the maximum possible information in the universe is $10^{10^{123}}$ whereas the maximum possible information that can be known by man is $10^{10^{90}}$. Can anyone explain to me how can we arrive at such a specific number, and also how can information be represented by only numbers?
Explore the mind-bending realms of the cosmos in our latest video! 🌌 From the Big Bang’s inception to the rapid expansion driven by dark energy, we’ll delve into how our universe grows endlessly.

OUTLINE:
Brain computer interface will have to be significantly more advanced before there’s an enhancement of cognitive abilities.
Devices that let people with paralysis walk and talk are rapidly improving. Some see a future in which we alter memories and download skills – but major challenges remain.
A mind-bending parasite may one day deliver drugs to the brain.
Toxoplasma gondii is a single-celled parasite that famously makes mice lose their fear of cats, but also can cause deadly foodborne illnesses (SN: 1/14/20).
Those with weakened immune systems have a higher risk of developing severe disease when exposed to T. gondii. Pregnant people run the risk of preterm birth and pregnancy loss. In addition, the parasite can cause a variety of problems for the baby including blindness, hearing loss, epilepsy and jaundice. More than 200,000 cases of toxoplasmosis are diagnosed each year in the United States, with about 5,000 requiring hospitalization. An estimated 750 people each year die from the disease.
Koshy’s own previous research indicates that brain cells the parasite injects a payload into eventually die.
If Mark Kelly, the Space Shuttle pilot who played a pivotal role in assembling the International Space Station, is catapulted into the White House as Vice President, he could quickly help reverse the death sentence that NASA’s current leaders have placed on the ISS.
Now a widely popular U.S. senator and potential running mate of Kamala Harris, Kelly spent the first decade of the new millennium ferrying European and Japanese modules to the Station — and guiding gigantic robotic builders to put the ISS together — all while the outpost was circling the planet at 17,000 miles per hour.
The space hero — recently inducted into the pantheon of the greatest American astronauts — is likely part of a contingent of ISS spacefarers who back saving the orbiting icon from NASA’s death decree by boosting it into a higher orbit and transforming it into an eternal monument to human ingenuity, says Rick Tumlinson, a torchbearer in the “Save Our Station,” or SOS movement.
Mathematics application to a new understanding thd world and life and information.
Dr. David Spivak introduces himself as a keynote speaker at the 17th Annual Artificial General Intelligence Conference in Seattle and shares his lifelong passion for math. He discusses his journey from feeling insecure about the world as a child, to grounding his understanding in mathematics.
Dr. Spivak is the Secretary of the Board at the Topos Institute and on the Topos staff as Senior Scientist and Institute Fellow, following an appointment as founding Chief Scientist. Since his PhD from UC Berkeley in 2007, he has worked to bring category-theoretic ideas into science, technology, and society, through novel mathematical research and collaboration with scientists from disciplines including Materials Science, Chemistry, Robotics, Aeronautics, and Computing. His mission at Topos is to help develop the ability for people, organizations, and societies to see more clearly—and hence to serve—the systems that sustain them.

Physicists say that they might have solved a long standing problem: How do supermassive black holes manage to merge to larger ones. Their idea: dark matter gets the job done. Or does it? I’ve had a look.
