Scientists Reveal How Much Sleep You Need For ‘Successful Aging’

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

We all want to ‘age successfully’ with as few health issues as possible. A new study suggests getting more than seven hours of sleep a night could go a long way to achieving that goal.

The study involved 3,306 participants aged 45 and over, whose sleep habits were recorded in 2011, 2013, and 2015, followed by a health check five years later. The data, analyzed by a team from Wenzhou Medical University in China, showed that those who bank at least seven hours of sleep a night tend to have significantly better health later in life.

“Successful aging was evaluated in 2020 and was defined as being free of major chronic diseases, no physical impairment, high cognitive function, good mental health, and active engagement with life,” write the researchers in their published paper.

MIT Scientists Develop New Way To Treat the Brain — Without Invasive Implants or Genetic Tweaks

Posted by in categories: bioengineering, biotech/medical, genetics, nanotechnology, neuroscience

Novel magnetic nanodiscs could provide a much less invasive way of stimulating parts of the brain, paving the way for stimulation therapies without implants or genetic modification, MIT researchers report.

The scientists envision that the tiny discs, which are about 250 nanometers across (about 1/500 the width of a human hair), would be injected directly into the desired location in the brain. From there, they could be activated at any time simply by applying a magnetic field outside the body. The new particles could quickly find applications in biomedical research, and eventually, after sufficient testing, might be applied to clinical uses.

The development of these nanoparticles is described in the journal Nature Nanotechnology, in a paper by Polina Anikeeva, a professor in MIT’s departments of Materials Science and Engineering and Brain and Cognitive Sciences, graduate student Ye Ji Kim, and 17 others at MIT and in Germany.

Consciousness Might Hide in Our Brain’s Electric Fields

Posted by in category: neuroscience

A mysterious electromagnetic mechanism may be more important than the firing of neurons in our brains to explain our awareness.

By Tamlyn Hunt

The neuron, the specialized cell type that makes up much of our brains, is at the center of today’s neuroscience. Neuroscientists explain perception, memory, cognition and even consciousness itself as products of billions of these tiny neurons busily firing their tiny “spikes” of voltage inside our brain.

Fish oil supplements may protect against cancer

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

In addition to lowering your cholesterol, keeping your brain healthy and improving mental health, new research from the University of Georgia suggests omega-3 and omega-6 fatty acids may help ward off a variety of cancers.

The study relied on data from more than 250,000 people and found that higher…


But most Americans probably aren’t eating enough of these foods to reach the recommended amounts.

One Stage of Sleep Seems to Be Critical in Reducing Dementia Risk

Posted by in categories: biotech/medical, neuroscience

The risk of getting dementia may go up as you get older if you don’t get enough slow-wave sleep. Over-60s are 27 percent more likely to develop dementia if they lose just 1 percent of this deep sleep each year, a 2023 study found.

Slow-wave sleep is the third stage of a human 90-minute sleep cycle, lasting about 20–40 minutes. It’s the most restful stage, where brain waves and heart rate slow and blood pressure drops.

Deep sleep strengthens our muscles, bones, and immune system, and prepares our brains to absorb more information. Recently, research discovered that individuals with Alzheimer’s-related changes in their brain did better on memory tests when they got more slow-wave sleep.

A cellular basis for mapping behavioural structure

Posted by in categories: mapping, neuroscience

A published today https://nature.com/articles/s41586-024-08145-x reveals brain cells can form a coordinate system for our behaviours.


Mice generalize complex task structures by using neurons in the medial frontal cortex that encode progress to task goals and embed behavioural sequences.
