Cancer is a disease driven by mutations that alter the way biochemical signals control cell growth, division and migration. Scientists found out that, like Goldilocks, cancer is very picky about getting rapid growth just right. from Top Health News -- ScienceDaily https://ift.tt/35QMqbz via IFTTT

Researchers think they've found a 'fountain of youth' in a rare genetic marker -- but it's unique to a few French-Canadian families. Called PCSK9Q152H, the mutation of the PCSK9 gene was initially thought to protect against cardiovascular diseases. Recent studies reveal that it may protect against other human illnesses, mainly liver diseases. from Top Health News -- ScienceDaily https://ift.tt/333DNIL via IFTTT

More than half of bacterial species in the core of the human gut microbiome are potentially sensitive to glyphosate, shows new research. Researchers introduced the first bioinformatics resource to determine and test the potential sensitivity of organisms to glyphosate. from Top Health News -- ScienceDaily https://ift.tt/3nHIxeT via IFTTT

Cells move constantly throughout our bodies, performing myriad operations critical to tissue development, immune responses and general wellbeing. This bustle is guided by chemical cues long studied by scientists interested in cellular migration. from Top Health News -- ScienceDaily https://ift.tt/390maNL via IFTTT

International development projects that target the education of the world's very poorest children also significantly improve other young people's attainment, research indicates. The findings are based on a study of a program targeting marginalized girls in Tanzania, which showed the attainment of other boys and girls at these pupils' schools significantly improved through 'spill-over' effects. For every $100 spent per girl, all students made the equivalent of two years of learning gains. from Top Health News -- ScienceDaily https://ift.tt/2KgOEIH via IFTTT

By combing the ocean for antimicrobials, scientists have discovered a new antifungal compound that efficiently targets multi-drug-resistant strains of deadly fungi without toxic side effects in mice. from Top Health News -- ScienceDaily https://ift.tt/3pM8Fr2 via IFTTT

Researchers have developed an ultrathin pressure sensor that can be attached directly to the skin. It can measure how fingers interact with objects to produce useful data for medical and technological applications. The sensor has minimal effect on the users' sensitivity and ability to grip objects, and it is resistant to disruption from rubbing. The team also hopes their sensor can be used for the novel task of digitally archiving the skills of craft workers. from Top Health News -- ScienceDaily https://ift.tt/36MmhK8 via IFTTT
