Forever Young: Scientists Reveal the Secret to a Strange Animal’s Eternal Youth

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

Sea anemones are seemingly immortal animals. They seem to be immune to aging and the negative impacts that humans experience over time. However, the exact reasons for their eternal youth are not completely understood.

The genetic fingerprint of the sea anemone Nematostella vectensis reveals that members of this incredibly ancient animal phylum employ the same gene cascades for neural cell differentiation as more complex organisms. These genes are also in charge of maintaining the balance of all cells in the organism during the anemone’s lifetime. These findings were recently published in the journal Cell Reports by a group of developmental biologists headed by Ulrich Technau of the University of Vienna.

Almost all animal organisms are made up of millions, if not billions, of cells that join together in intricate ways to create specific tissues and organs, which are made up of a range of cell types, such as a variety of neurons and gland cells. However, it is unclear how this critical balance of diverse cell types emerges, how it is regulated, and if the different cell types of different animal organisms have a common origin.

Long COVID study suggests lost connections between neurons may explain cognitive symptoms

Posted by in categories: biotech/medical, neuroscience

For a portion of people who get COVID, symptoms continue for months or even years after the initial infection. This is commonly referred to as “long COVID”.

Some people with long COVID complain of “brain fog”, which includes a wide variety of cognitive symptoms affecting memory, concentration, sleep and speech. There’s also growing concern about findings that people who have had COVID are at increased risk of developing brain disorders, such as dementia.

Scientists are working to understand how exactly a COVID infection affects the human brain. But this is difficult to study, because we can’t experiment on living people’s brains. One way around this is to create organoids, which are miniature organs grown from stem cells.

Warning: Popular Vitamin Supplement Causes Cancer Risk and Brain Metastasis

Posted by in categories: biotech/medical, life extension, neuroscience

University of Missouri researchers made the discovery while using bioluminescent imaging technology to study how nicotinamide riboside supplements work inside the body.

Commercial dietary supplements like nicotinamide riboside (NR), a form of vitamin B3, were linked to benefits related to cardiovascular, metabolic, and neurological health in previous studies. However, new research from the University of Missouri (MU) has found NR could actually increase the risk of serious disease, including developing cancer.

Supplements containing nicotinamide riboside are often marketed as NAD+ boosters claimed benefits including increased energy, anti-aging/longevity/healthy aging, improved cellular energy metabolism and repair, increased vitality, and improved heart health.

A discussion with Dr. Nir Barzaili on Age Later

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

Ever wonder why some 90-year olds don’t seem to slow down and seem. to retain the mental and physical capacity of someone half their age?
Do they have good genes? Or is there a way that all of us can get older without getting old?

That’s what Dr. Nir Barzilai, founder of the Institute for Aging Research at the Albert Einstein College of Medicine, set out to answer in his book, Age Later.

Scientists found a way for people with paralysis to walk again

Posted by in categories: biotech/medical, neuroscience

Scientists have managed to do what many might have thought impossible. According to new research published in the journal Nature, a group of researchers from the Swiss research group NeuroRestore was able to identify neurons that could restore the ability to walk in paralyzed individuals. The researchers published their findings back in September.

Qatar 2022 FIFA World Cup: Technologically advanced stadiums will cater to the needs of specially-abled

Posted by in category: neuroscience

The stadiums include a quiet room for those with cognitive disabilities.

The FIFA World Cup to be held in Qatar this year is leading the way in accessibility for specially-abled people, according to a report by Euronews.

The technologically advanced stadiums aren’t only wheelchair accessible, other amenities have also been included, such as a quiet room for those suffering from autism and other cognitive disabilities. The room is meant to give a safe haven for those overwhelmed by the World Cup’s loud crowds.

Clever Machines Learn How to Be Curious

Posted by in categories: computing, information science, neuroscience

“You can think of curiosity as a kind of reward which the agent generates internally on its own, so that it can go explore more about its world,” Agrawal said. This internally generated reward signal is known in cognitive psychology as “intrinsic motivation.” The feeling you may have vicariously experienced while reading the game-play description above — an urge to reveal more of whatever’s waiting just out of sight, or just beyond your reach, just to see what happens — that’s intrinsic motivation.

Humans also respond to extrinsic motivations, which originate in the environment. Examples of these include everything from the salary you receive at work to a demand delivered at gunpoint. Computer scientists apply a similar approach called reinforcement learning to train their algorithms: The software gets “points” when it performs a desired task, while penalties follow unwanted behavior.

Rats bopping to the beat in video demonstrate innate beat synchronization in animals for the first time

Posted by in categories: media & arts, neuroscience

Rats love to dance 🕺:3


The team had two alternate hypotheses: The first was that the optimal music tempo for beat synchronicity would be determined by the time constant of the body. This is different between species and much faster for compared to humans (think of how quickly a rat can scuttle). The second was that the optimal tempo would instead be determined by the time constant of the brain, which is surprisingly similar across species.

“After conducting our research with 20 human participants and 10 rats, our results suggest that the optimal tempo for beat synchronization depends on the time constant in the brain,” said Takahashi. “This demonstrates that the animal brain can be useful in elucidating the perceptual mechanisms of music.”
