Simple microparticles can beat rhythmically together, generating an oscillating electrical current that could be used to power micro-robotic devices.
MIT is an acronym for the Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; engineering; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances. Their stated goal is to make a better world through education, research, and innovation.
What is limb regeneration and what species possess it? How is it achieved? What does this tell us about intelligence in biological systems and how could this information be exploited to develop human therapeutics? Well, in this video, we discuss many of these topics with Dr Michael Levin, Principal Investigator at Tufts University, whose lab studies anatomical and behavioural decision-making at multiple scales of biological, artificial, and hybrid systems.

Algorithms have helped mathematicians perform fundamental operations for thousands of years. The ancient Egyptians created an algorithm to multiply two numbers without requiring a multiplication table, and Greek mathematician Euclid described an algorithm to compute the greatest common divisor, which is still in use today.
During the Islamic Golden Age, Persian mathematician Muhammad ibn Musa al-Khwarizmi designed new algorithms to solve linear and quadratic equations. In fact, al-Khwarizmi’s name, translated into Latin as Algoritmi, led to the term algorithm. But, despite the familiarity with algorithms today – used throughout society from classroom algebra to cutting edge scientific research – the process of discovering new algorithms is incredibly difficult, and an example of the amazing reasoning abilities of the human mind.
In our paper, published today in Nature, we introduce AlphaTensor, the first artificial intelligence (AI) system for discovering novel, efficient, and provably correct algorithms for fundamental tasks such as matrix multiplication. This sheds light on a 50-year-old open question in mathematics about finding the fastest way to multiply two matrices.
“The idea was to build a society like we have for all the other disciplines in medicine,” says Evelyne Bischof, a professor of medicine at Shanghai University of Medicine and Health Sciences and the inaugural vice president of the society. She has previously spearheaded educational efforts with Zhavoronkov and others, co-developing a formal course on longevity medicine for doctors. At the ARDD meeting, Bischof announced their course had just received continuing medical education (CME) accreditation from the American Medical Association.
“Longevity medicine is crystallizing as a discipline,” says Andrea Maier, an internal medicine specialist and geriatrician at National University of Singapore who is serving as the society’s inaugural president. One thing that’s not yet clear, several experts told me, is whether longevity will come to be established as a sub-discipline of geriatrics or internal medicine or whether it will become a separate medical specialty unto itself.
“Whichever way it goes,” Maier says, “it’s happening.”
This metaverse meme video is about wojak who grows old in a metaverse. From the moment he is still a child and has his first school day, he already lives through his vr glasses. His school is in the metaverse, as well as his friends. Years later, he starts doubting about how “normal” living meta actually is. Didn’t people maybe have a better life back when there was no metaverse? When you did stuff offline? Who knows…

You may not realize it, but each time you recall a memory—like your first time riding a bike or walking into your high school prom—your brain changes the memory ever so slightly. It’s almost like adding an Instagram filter, with details being filled in and information being updated or lost with each recall.
“We’re inadvertently applying filters to our past experiences,” says Steve Ramirez, a Boston University neuroscientist. Even though a filtered memory is different from the original, you can tell what that basic picture is, for the most part, he says.
“Memory is less of a video recording of the past, and more reconstructive,” says Ramirez, a BU College of Arts & Sciences assistant professor of psychological and brain sciences. The malleable nature of memory is both a blessing and curse: It’s bad if we remember false details, but it’s good that our brains have the natural ability to mold and update memories to make them less potent, especially if it is something scary or traumatic.
If there is one thing science fiction movies and comics have taught us, it’s that humans have no. limitations, and we will one day be able to open a portal that transverses into another dimension. What if I tell you that day is closer to us than ever? This is the latest discovery made. by scientists and is by far the biggest of the century. Will we finally get to find out if we are the only beings in the cosmos? What technology have. scientists designed capable of making interstellar teleportation possible? How and where will. the portals take us? Join us as we explore how scientists have finally found a way to open a portal to another. dimension.

Set to be one of the largest, if not the largest, investment opportunity in the decades to come, longevity is a rapidly accelerating field; the Longevity Investors Conference targets the global investor community, bringing together institutional investors and top class experts for networking and exploration of relevant insights into the field, as well as expert education and investment opportunities.
Strenuous cognitive work leads to an accumulation of glutamate in the prefrontal cortex, according to new research published in the journal Current Biology. The new findings suggest that mental fatigue is a neuropsychological mechanism that helps to avert the build up of potentially toxic byproducts of prolonged cognitive activity.
“Nobody knows what mental fatigue is, how it is generated and why we feel it,” said study author Antonius Wiehler, a member of the Motivation, Brain and Behavior Lab at Pitié Salpêtrière Hospital in Paris. “It has remained a mystery despite more than a century of scientific research. Machines can do cognitive tasks continuously without fatigue, the brain is different and we wanted to understand how and why. Mental fatigue has important consequences: for economic decisions, for management at work, for education at school, for clinical cure, etc.”
The researchers were particularly interested in the role of glutamate, an excitatory neurotransmitter that is involved in a variety of cognitive functions, including learning and memory. In addition, glutamate plays a role in controlling the strength of synaptic connections. Too much or too little glutamate can lead to neuronal dysfunction, so it is critical that this neurotransmitter is tightly regulated.
