Extra-virgin olive oil prevents dementia by clearing brain of debris

Extra-virgin olive oil prevents dementia by prompting the brain to clear out harmful debris, reveal scientists as they hail ‘exciting’ breakthrough

  • Oil is a key ingredient of a Mediterranean diet, which has many health benefits
  • Study found olive oil prompts the brain to remove harmful clutter in the brain
  • Olive oil reduces the amount of amyloid-beta plaques and neurofibrillary tangles
  • These structures increase a person’s likelihood of getting Alzheimer’s disease

DNA Replication Has Been Filmed For The First Time, And It’s Not What We Expected

“It undermines a great deal of what’s in the textbooks.”

Here’s proof of how far we’ve come in science – in a world-first, researchers have recorded up-close footage of a single DNA molecule replicating itself, and it’s raising questions about how we assumed the process played out.

The real-time footage has revealed that this fundamental part of life incorporates an unexpected amount of ‘randomness’, and it could force a major rethink into how genetic replication occurs without mutations.

Playing with the fire of inflammation

Inflammation is like a fire in your body you cannot see or feel. “It’s a smoldering process that injures your tissues, joints, and blood vessels, and you often do not notice it until significant damage is done,” says Dr. Andrew Luster, of the Center for Immunology and Inflammatory Diseases at Harvard-affiliated Massachusetts General Hospital. The damage might show up as arthritis, heart disease, stroke, and even Alzheimer’s disease.

A New Study Examines The Deep Benefits Of Meditation, Yoga And Tai Chi

Mind-body interventions (MBIs) such as meditation, yoga and Tai Chi don’t simply relax us; they can ‘reverse’ the molecular reactions in our DNA which cause ill-health and depression, according to a study by the Universities of Coventry and Radboud.

The research, published in the journal Frontiers in Immunology, reviews over a decade of studies analysing how the behaviour of our genes is affected by different MBIs including mindfulness and yoga.

Experts from the universities conclude that, when examined together, the 18 studies — featuring 846 participants over 11 years — reveal a pattern in the molecular changes which happen to the body as a result of MBIs, and how those changes benefit our mental and physical health.

The researchers focus on how gene expression is affected; in other words, the way that genes activate to produce proteins which influence the biological make-up of the body, the brain and the immune system.

Omega-3 and Omega-6 Fatty Acids May Help Healthy Brain Aging

Omega-3 and Omega-6 Fatty Acids May Help Healthy Brain Aging

Two new studies link patterns of polyunsaturated fatty acids in the blood to the integrity of brain structures and cognitive abilities that are known to decline early in aging.

The studies add to the evidence that dietary intake of omega-3 and omega-6 fatty acids can promote healthy aging, the researchers said. Further research is needed to test this hypothesis, they said.

The brain is a collection of interconnected parts, each of which ages at its own pace. Some brain structures, and the abilities they promote, start to deteriorate before others, said University of Illinois M.D./Ph.D student Marta Zamroziewicz, who led the new research with psychology professor Aron Barbey.

Here is how to focus and use more of your brain

It’s a myth that humans only use 10% of their brains. “That idea is not only inaccurate, it doesn’t make any sense,” says Earl Miller, a professor of Neuroscience at the Picower Institute for Learning and Memory at the Massachusetts Institute of Technology. “Even the simplest behaviours engage much of our brain.”

But while that old 10% dictum is bogus, it’s true that many of us have some untapped reserves of mental acuity that, if harnessed, could sharpen our powers of insight and analysis. The key to accessing those reserves, Miller says, is to stay focused. “The main thing that impedes our cognition is distraction.”

Distractions are powerful drains on the brain’s ability to focus, and one of the best ways to get more from your mind is to give yourself the gift of uninterrupted stretches of time.

Exercising for just an hour a week lowers risk of diabetes

 

  • Increasing the amount or intensity of weight training did not lower risk further
  • Resistance exercise combined with aerobic exercise saw greatest benefit
  • Whether you do cardio or not, weight training is recommended, say experts
  • Two 30-minute sessions per week of resistance exercise has the best effect
  • 1 in 4 UK adults has diabetes, high blood pressure and obesity combined 
  • This was the first study to look at resistance exercise and metabolic syndrome
