Alzheimer’s disease is a truly terrifying condition, one that is difficult to detect early and increasingly difficult to treat over time. It’s incurable, and there is no single test that can currently give an accurate diagnosis; the ability to identify the condition early would greatly assist physicians in learning how the disease begins and progresses. A new study published in Science hopes to do just that, by looking at the brain’s navigation network.
Scientists often discover disease-fighting compounds in all sorts of weird and wonderful places. Anti-cancer molecules have been found in corals and wasp venom of all places, and antibacterial agents have been sourced from the bright blue blood of horseshoe crabs. Now, to add to this bizarre list, it turns out that bananas might soon be added to our antiviral armamentarium.
Resveratrol, a compound produced by a range of plants, has been making headlines over the last year or so, with studies sharply divided on how beneficial said molecule may or may not be to human health. A group of researchers and bioengineers at the John Innes Centre have decided to fall firmly on one side of the fence, announcing that they have discovered a way to make resveratrol in industrial quantities by producing it in genetically modified tomatoes, along with other phenylpropanoids, a group of compounds resveratrol belongs to.
As we age, our brains naturally shrink and our risk of having a stroke, dementia or Alzheimer’s rise, and almost everyone experiences some kind of memory loss.Scientists know that people who exercise regularly, eat a healthy diet, avoid smoking and keep mentally stimulated generally have healthier brains than people who aren’t as careful about diet and exercise. This latest study from the journal Neurology shows how one easy-to-follow diet (which includes wine!) may make your brain about five years younger.
The World Health Organisation (WHO) released a report Monday which placed processed meats, including bacon and sausages, in the same category as smoking and asbestos for causing cancer.Processed meat causes cancer, says WHOThe report revealed that as little as two slices of bacon can increase the risk of colorectal (bowel) cancer by 18%.
Staphylococcus aureus is an intimidating and challenging bacterium. It is responsible for a wide variety of human maladies, from annoying skin pimples to deadly meningitis. It’s pervasive and numerous strains have evolved antibiotic resistance, but perhaps most famously the “superbug” MRSA (methicillin-resistant S. aureus). While the arms race to fight them off continues, an international team of scientists has found a potential way to reduce the damage from infection. This could improve survival chances of patients with serious infections like pneumonia or the potentially fatal toxic shock syndrome.
