The Brain Has a ‘Low-Power Mode’ That Blunts Our Senses

Posted by in categories: computing, food, mobile phones, neuroscience

When our phones and computers run out of power, their glowing screens go dark and they die a sort of digital death. But switch them to low-power mode to conserve energy, and they cut expendable operations to keep basic processes humming along until their batteries can be recharged.

Our energy-intensive brain needs to keep its lights on too. Brain cells depend primarily on steady deliveries of the sugar glucose, which they convert to adenosine triphosphate (ATP) to fuel their information processing. When we’re a little hungry, our brain usually doesn’t change its energy consumption much. But given that humans and other animals have historically faced the threat of long periods of starvation, sometimes seasonally, scientists have wondered whether brains might have their own kind of low-power mode for emergencies.

Now, in a paper published in Neuron in January, neuroscientists in Nathalie Rochefort’s lab at the University of Edinburgh have revealed an energy-saving strategy in the visual systems of mice. They found that when mice were deprived of sufficient food for weeks at a time — long enough for them to lose 15%-20% of their typical healthy weight — neurons in the visual cortex reduced the amount of ATP used at their synapses by a sizable 29%.

Gut microbiome acts on the brain to control appetite

Posted by in categories: biotech/medical, food, neuroscience

The brain is the central information center and constantly monitors the state of every organ present in a body. Previous research has shown that the brain also receives signals from the gut microbiota.

In a new Immunity journal study, researchers discuss the work of Gabanyi et al. (2022), published in a recent issue of Science, which reveals that hypothalamic gamma-aminobutyric acid (GABAergic) neurons recognize microbial muropeptides through the cytosolic receptor NOD2, which regulates food intake and body temperature.

Microsoft Lasers Music into Glass for 1000 Years of Storage

Posted by in categories: food, information science, media & arts, nanotechnology, robotics/AI, security

Philip Glass to release a short silence on the matter.

The music vault is a parallel project to the Global Seed Vault (opens in new tab), which keeps the seeds of today’s trees and plants safe for the future, just in case we need to rebuild agriculture for any reason. The vault is located on the island of Spitsbergen, Norwegian territory, within the Arctic circle. It lacks tectonic activity, is permanently frozen, is high enough above sea level to stay dry even if the polar caps melt, and even if the worst happens, it won’t thaw out fully for 200 years. Just to be on the safe side, the main vault is built 120m into a sandstone mountain, and its security systems are said to be robust. As of June 2021, the seed vault had conserved 1,081,026 different crop samples.

The music is to be stored in a dedicated vault in the same mountain used by the seed vault. The glass used is an inert material, shaped into platters 75mm (3 inches) across and 2mm (less than 1/8th of an inch) thick. A laser encodes data in the glass by creating layers of three-dimensional nanoscale gratings and deformations. Machine learning algorithms read the data back by decoding images and patterns created as polarized light shines through the glass. The silica glass platters are fully resistant to electromagnetic pulses and the most challenging of environmental conditions. It can be baked, boiled, scoured and flooded without degradation of the data written into the glass. Tests to see if it really does last many thousands of years, however, can be assumed to be ongoing.

AI enters archaeology, scientists use algorithms to discover evidence of human use of fire nearly 1 million years ago

Posted by in categories: food, information science, robotics/AI

The use of fire was a key factor in the evolution of Homo sapiens, not only for the creation of more sophisticated tools but also for making food safer, which in turn aided brain development.

To date, only five sites with fire evidence dating back 500,000 years have been found worldwide, including Wonderwerk Caves and Swartkrans in South Africa, Chesowanja in Kenya, Gesher Benot Ya’aqov in Israel, and Cueva Negra in Spain.

Now, a n Israeli research team has used artificial intelligence algorithms to discover a sixth site that shows traces of human fire! The study revealed evidence of human use of fire at a late Paleolithic site in Israel. The research results have been published in the journal PNAS.

Exercise pill could curb food cravings for people who lack physical activity

Posted by in categories: biotech/medical, food, health

STANFORD, Calif. — An “anti-hunger” pill could be on the horizon, according to a new study. Researchers from Stanford Medicine and Baylor University have identified a molecule that keeps people from getting hungry after exercising.

In experiments, the compound dramatically reduced food intake and obesity in mice. Study authors hope to turn it into a medication that may even replace the need to go to the gym.

The Future Of | Official Trailer | Netflix

Posted by in categories: augmented reality, food, internet, wearables

What if we could look into the future to see how every aspect of our daily lives – from raising pets and house plants to what we eat and how we date – will be impacted by technology? We can, and should, expect more from the future than the dystopia promised in current science fiction. The Future Of… will reveal surprising and personal predictions about the rest of our lives — and the lives of generations to come.
