Biomechanical interactions, rather than neurons, control the movements of one of the simplest animals. The discovery offers a glimpse into how animal behavior worked before neurons evolved.
Tesla has unveiled its latest version of its Dojo supercomputer and it’s apparently so powerful that it tripped the power grid in Palo Alto.
Dojo is Tesla’s own custom supercomputer platform built from the ground up for AI machine learning and more specifically for video training using the video data coming from its fleet of vehicles.
The automaker already has a large NVIDIA GPU-based supercomputer that is one of the most powerful in the world, but the new Dojo custom-built computer is using chips and an entire infrastructure designed by Tesla.
Breakthrough opens up new possibilities for the creation of next-generation materials.
A new way to self-assemble particles has been created by a team of physicists. This advance offers new promise for building complex and innovative materials at the microscopic level.
Self-assembly, introduced in the early 2000s, gives scientists a means to “pre-program” particles, which allows for the construction of materials without further human intervention. This is basically the microscopic equivalent of Ikea furniture that can assemble itself.
Hydrogen generation using abundant solar energy together with semiconductor photocatalysts holds significant potential to produce clean and sustainable energy carriers.
ETH Zurich researchers have developed a new photocatalyst made from an aerogel that could enable more efficient hydrogen production. The aerogel increases the efficiency of converting light into hydrogen energy, producing up to 70 times more hydrogen than rival methods.
Aerogels are extraordinary materials that have set Guinness World Records more than a dozen times, including the honorary position of becoming one of the world’s lightest solids. Professor Markus Niederberger from the Laboratory for Multifunctional Materials at ETH Zurich has been working with these special materials for some time.
Scientists managed to start the same chemical process that powers the Sun on August 8, 2021, by putting more electricity into a tiny gold capsule than the entire US electric system could handle.
It is extremely astonishing how the power of 192 laser beams sparked the same thermonuclear fire that fuels the Sun for a nanosecond.
The Sun produces energy by hurling hydrogen atoms together, generating helium in the process. We are now closer than ever to being able to harness chemical reactions with enough force to power the Sun. This is possible because fusion power technology has advanced.
More than 50 cases have been identified so far in an outbreak linked to the Sudan variant of Ebola virus, which has no approved treatment or vaccine.
Putin has previously threatened to resort to nuclear weapons if Russia’s goals in Ukraine continue to be thwarted. The annexation brings the use of a nuclear weapon a step closer by giving Putin a potential justification on the grounds that “the territorial integrity of our country is threatened,” as he put it in his speech last week.
He renewed the threat on Friday with an ominous comment that the U.S. atomic bombing of Hiroshima and Nagasaki created a “precedent” for the use of nuclear weapons, echoing references he has made in the past to the U.S. invasion of Iraq as setting a precedent for Russia’s invasion of Ukraine.
Summary: Neurons in the memory-associated entorhinal cortex of super-agers are significantly larger than their cognitively average peers, those with MCI, and even in people up to 30 years younger. Additionally, these neurons contained no signs of Tau, a hallmark of Alzheimer’s disease.

Neurons in an area of the brain responsible for memory (known as the entorhinal cortex) were significantly larger in SuperAgers compared to cognitively average peers, individuals with early-stage Alzheimer’s disease and even individuals 20 to 30 years younger than SuperAgers — who are aged 80 years and older, reports a new Northwestern Medicine study.
Based on an analysis of just under half a million records in the UK Biobank, people who drink two to three cups of coffee each day tend to live longer and exhibit less cardiovascular disease compared with those who abstain from the beverage.
While the research doesn’t claim drinking more coffee adds years to your life, it’s nevertheless an intriguing association that scientists are keen to investigate further. It’s also important to weigh the findings against previous studies linking brain shrinkage and an increased risk of dementia with a daily habit of six or more cups of coffee.
“In this large, observational study, ground, instant and decaffeinated coffee were associated with equivalent reductions in the incidence of cardiovascular disease and death from cardiovascular disease or any cause,” says electrophysiologist Peter Kistler, from the Baker Heart and Diabetes Institute in Australia.
All humans are believers

Science and religion both flirt with the unknown. Belief is not just about God or ghosts but is an essential need for all humans.
