Physicists have successfully played a mind-bending “quantum game” using a real-world quantum computer, in which lasers shuffle around ions on a chip to explore the strange behavior of qubits. By creating a special, knotted structure of entangled particles, the team demonstrated that today’s quant

These electrical pulses are communicated with other neurons through connections between them called synapses. Individual neurons have branching extensions known as dendrites that can receive thousands of electrical inputs from other cells. Dendrites transmit these inputs to the main body of the neuron, where it then integrates all these signals to generate its own electrical pulses.
It is the collective activity of these electrical pulses across specific groups of neurons that form the representations of different information and experiences within the brain.
For decades, neuroscientists have thought that the brain learns by changing how neurons are connected to one another. As new information and experiences alter how neurons communicate with each other and change their collective activity patterns, some synaptic connections are made stronger while others are made weaker. This process of synaptic plasticity is what produces representations of new information and experiences within your brain.
Dysregulation of the Kynurenine Pathway in Relapsing Remitting Multiple Sclerosis and Its Correlations With Progressive Neurodegeneration

Background and ObjectivesDespite the absence of acute lesion activity in multiple sclerosis (MS), chronic neurodegeneration continues to progress, and a potential underlying mechanism could be the kynurenine pathway (KP). Prolonged activation of the KP…
Dehydration can sneak up on you. Whether you’re out jogging or sitting at a desk, it’s easy to lose track of your fluid intake. But a new, tiny sweat sensor may soon solve this problem. Designed by UC Berkeley researchers, this wearable device can measure changes in your hydration status and help you decide when it’s time to take a break and get some water.
In a study recently published in Nature Electronics, researchers demonstrated how their sweat sensor measures electrodermal activity (EDA), an electrical property of the skin, to monitor hydration levels during physical activity. Until now, EDA, or skin conductance, has been thought to be effective at assessing only mental stress.
These findings could broaden EDA’s role in physiological monitoring and someday provide a simple way for people to also avoid dehydration.
Want To Live To 100? Experts Reveal 3 Anti-Aging & Longevity Secrets That Can ‘Repair Your Body’ And Prevent Aging: Prioritize Sleep, More

Living to 100 may sound like a dream, but thanks to advancements in anti-aging and longevity research, it’s becoming more of a realistic goal than ever before. While genetics play a role, experts say your daily habits have a major impact on how gracefully—and healthfully—you age. From diet and movement to mindset and skincare, there are key lifestyle shifts and science-backed secrets that can help slow the aging process, boost vitality, and support a longer, more vibrant life.
Robert Love, a neuroscientist, shared three anti-aging and longevity secrets you should know about if you want to “slow down aging” and “even help reverse aging.” According to him, prioritizing sleep, avoiding ultra-processed foods, and taking healthy supplements are some of the best options. Read on to learn more.
Prioritizing sleep is one of the most powerful (and underrated) anti-aging tools you have. During deep sleep, your body goes into repair mode—producing growth hormone, regenerating cells, and fixing damage caused by stress and environmental factors. This nightly “reset” helps keep your skin, organs, and even brain functioning optimally.

NAQI: Northeastern University scientists have discovered that a protein in the human brain could potentially be used to grow new neurons in the lab and enhance brain processes affected by aging or neurodegenerative diseases

In their study, published in Mechanobiology in Medicine, the researchers discovered that the protein responsible for binding neural stem cells in the human brain, neuro-cadherin, also plays a key role in stimulating their differentiation.
Neural stem cells are early-stage, unspecialized cells that have the ability to differentiate, or develop, into various types of neurons and non-neuronal cells of the central nervous system.
As the first generation that interacted with digital technology reaches an age where dementia risks emerge, scientists have asked the question: Is there a correlation between digital technology use and an increased risk of dementia? With the phrases “brain rot” and “brain drain” circulating on social media, it would appear that most people would assume the answer is yes.
However, a new study in Nature Human Behavior by neuroscientists at Baylor University and the University of Texas at Austin Dell Medical School reveals the opposite—digital technologies are actually associated with reduced cognitive decline.
The study, “A meta-analysis of technology use and cognitive aging,” was sparked by the ongoing concern about the passive activity of digital technologies and their relation to accelerating risks of dementia. Study co-authors are Jared F. Benge, Ph.D., clinical neuropsychologist and associate professor of neurology at Dell Medical School and UT Health Austin’s Comprehensive Memory Center within the Mulva Clinic for the Neurosciences, and Michael K. Scullin, Ph.D., associate professor of psychology and neuroscience at Baylor.
