Study sheds light on damage linked to aging

Some of the damaging cell effects linked to ageing could be prevented by manipulating tiny parts of cells, a study shows. Scientists have shed light on how the harm caused by senescence – a vital cell process that plays a key role in diseases of ageing – could be controlled or even stopped. Researchers say ..

Romance: Deal makers and breakers

(HealthDay)—A global study about what men and women want in a mate seems to confirm—to a point—long-established stereotypes. Men still go for looks—in general they said their preference is for a partner who is younger and physically attractive. Women said they’d prefer an older partner who’s ambitious and has good financial prospects. The researchers, from ..

Aspartame and artificial sweeteners – helping or hindering weight loss?

With our appetite for low or zero sugar products increasing, artificial sweeteners are big business. Food or drinks containing artificial sweeteners are often marketed as a healthier option, and it’s understandable why. Because artificial sweeteners are significantly sweeter than sugar, they can be used in very small amounts and contribute little to no calories. There ..

Electrical activity early in fruit flies’ brain development could shed light on how neurons wire the brain

The UCLA scientists observed consistent bursts of electrical activity in the developing brain of fruit flies. T4 and T5 indicate individual neurons firing.  Neurons somehow know which of their neighbors to connect with and which to avoid in the crowded environment of the central nervous system. But how? Using fruit flies, neuroscientists from the David ..

Study recommends reconsidering hepatitis A vaccination protocol to prevent a vaccine-resistant virus

Researchers of the University of Barcelona (UB) have used massive sequencing techniques with samples from patients to determine the evolution of the hepatitis A virus. The results, published in the journal EBioMedicine, show the presence of variants of the virus that could escape the effects of the vaccine. The study, led by the Research Group ..

RNAs play key role in protein aggregation and in neurodegenerative disease, according to new research

New research reveals RNAs, which are crucial for cells to produce proteins, are also involved in protein aggregation, where proteins do not fold properly and ‘clump’ together into aggregates. If cells cannot clear these away, they become toxic and prevent cells working properly. This discovery, led by scientists at the Centre for Genomic Regulation (CRG) ..

Researchers answer decades-old question about protein found in Alzheimer’s brain plaques

Credit: CC0 Public Domain Alzheimer’s-affected brains are riddled with amyloid plaques, protein aggregates consisting mainly of amyloid-β. However, amyloid-β is a fragment produced from a precursor protein whose normal function has remained enigmatic for decades. A team of scientists at VIB and KU Leuven led by professors Joris de Wit and Bart De Strooper has ..

Researchers map previously unknown disease in children

Credit: CC0 Public Domain Two children from Europe and one from Canada, aged four, six and 10, suffer from a previously unknown disease that causes epileptic seizures, loss of magnesium and reduced intelligence. There is currently no way to treat or alleviate their symptoms. But researchers in an international consortium have now discovered the cause ..
