Low levels of a simple sugar — A new biomarker for severe MS? — ScienceDaily


Multiple sclerosis, or MS for short, manifests itself slightly differently in each person — which is why some call it “the disease of a thousand faces.” Arguably the worst manifestation of MS is its chronic progressive form. Unlike the more common relapsing-remitting variant (RRMS), in which sufferers are often symptom-free for months or even years, […]

new research offers hope for Alzheimer’s disease — ScienceDaily


Since the discovery of Alzheimer’s disease over a century ago, two hallmarks of the devastating illness have taken center stage. The first, known as amyloid plaques, are dense accumulations of misfolded amyloid protein, occurring in the spaces between nerve cells. Most efforts to halt the advance of Alzheimer’s disease have targeted amyloid protein plaques. To […]

A once-in-a-lifetime jab may treat back pain. In a new trial, injections of lactic acid — a syrup-like substance formed in sour milk and found naturally in our bodies — are being given to 120 patients with lower back pain caused by disc problems. The researchers say that the jab will make the discs, which […]

Baby girl is spared a lifetime of paralysis after operation inside the WOMB


A baby girl has been spared a lifetime of disability after receiving pioneering spinal surgery — while still in the womb. Emily Malkie, from Pennsylvania, was diagnosed with spina bifida following an ultrasound when her mother was just 16 weeks pregnant. A follow-up MRI showed the youngster was at risk of developing brain damage due to a […]

Process for eliminating unneeded cells may also protect against cancer — ScienceDaily


For all animals, eliminating some cells is a necessary part of embryonic development. Living cells are also naturally sloughed off in mature tissues; for example, the lining of the intestine turns over every few days. One way that organisms get rid of unneeded cells is through a process called extrusion, which allows cells to be […]

Nearly half of older millennials already have chronic health conditions, a new survey suggests.  Some 44 percent of people born between 1981 and 1988 have already been diagnosed with at least one chronic medical condition, according to the CNBC/Harris poll.  The most common conditions among the group were migraines, depression and asthma, diabetes type 2 […]

A Mediterranean diet might protect against memory loss and dementia — ScienceDaily


In Alzheimer’s disease, neurons in the brain die. Largely responsible for the death of neurons are certain protein deposits in the brains of affected individuals: So-called beta-amyloid proteins, which form clumps (plaques) between neurons, and tau proteins, which stick together the inside of neurons. The causes of these deposits are as yet unclear. In addition, […]

Epilepsy research reveals why sleep increases risk of sudden death — ScienceDaily


New research from the University of Virginia School of Medicine reveals why sleep can put people with epilepsy at increased risk of sudden death. Both sleep and seizures work together to slow the heart rate, the researchers found. Seizures also disrupt the body’s natural regulation of sleep-related changes. Together, in some instances, this can prove […]

Exercise aids the cognitive development of children born preterm — ScienceDaily


A premature start in life can cause problems even into teenage years.

Why do some neurons degenerate and die in Alzheimer’s disease, but not others? — ScienceDaily


In the brain of a person with Alzheimer’s disease, neurons degenerate and die, slowly eliminating memories and cognitive skills. However, not all neurons are impacted equally. Some types of neurons in certain brain regions are more susceptible, and even among those subtypes — mysteriously — some perish and some do not. Researchers at Gladstone Institutes […]

Damage to white matter is linked to worse cognitive outcomes after brain injury — ScienceDaily


A new University of Iowa study challenges the idea that gray matter (the neurons that form the cerebral cortex) is more important than white matter (the myelin covered axons that physically connect neuronal regions) when it comes to cognitive health and function. The findings may help neurologists better predict the long-term effects of strokes and […]

Cancer-linked mutation accelerates growth of abnormal stroke-causing brain blood vessels — ScienceDaily


Researchers have discovered an explanation for why cerebral cavernous malformations (CCMs) — clusters of dilated blood vessels in the brain — can suddenly grow to cause seizures or stroke.

DR MICHAEL MOSLEY: Can eating too much be a sign your body lacks nutrients?


For most people, the past 12 months have been really tough, but some businesses have thrived — it seems 2020 was a fantastic year for supplement manufacturers, with nearly £500 million in UK sales, up a record 14 per cent compared with 2019. We swallowed their products in record numbers partly because we’re all more […]

Hippocampal maps predict context-dependent behavior — ScienceDaily


Successful navigation requires the ability to separate memories in a context-dependent manner. For example, to find lost keys, one must first remember whether the keys were left in the kitchen or the office. How does the human brain retrieve the contextual memories that drive behavior? J.B. Julian of the Princeton Neuroscience Institute at Princeton University, […]

Hooked on the ANXIETY pills experts are calling the new VALIUM


Sharon Davies has a simple message for anyone whose GP recommends they start taking the drug pregabalin to deal with anxiety. ‘Don’t,’ she says. ‘Please, just don’t.’ During the two years she spent on the drug, Sharon experienced a range of ‘unbearable’ side-effects, including dizzy spells, mental ‘fuzziness’ and extreme weight gain. Then, in July […]

Should you ignore the food traffic lights?


You see them on food packets — red, amber and green colours that are supposed to depict whether the food you are putting in your basket is healthy — or not. Introduced in 2013 by the Food Standards Agency, the traffic light colours are assigned for levels of fat, saturated fat, sugar and salt. The […]

A new perspective on the genomes of archaic humans — ScienceDaily


A genome by itself is like a recipe without a chef — full of important information, but in need of interpretation.
