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 ..

(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 ..

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 ..

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 ..

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 ..

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) ..
