Surprising study shows reduced neuronal activity extends life

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

Say this about the kinds of molecular mayhem that we know underlie aging: Mechanisms like whether the ends of chromosomes fray (bad) and whether genes’ on-off status breaks down (really bad) at least sound like plausible ways to impair vital organs, from skin to brains and hearts, and produce the whole sorry mess known as aging.

On Wednesday, scientists reported a driver of aging that, in contrast, even the lead researcher diplomatically calls “counterintuitive”: neuronal activity. Aging, of course, affects the brain. But the brain seems to affect aging, too, they found: In creatures from worms to mice to people, high levels of neuronal firing spell a shorter life span. Lower levels — naturally, or due to drugs that dampen neurons’ activity — increase longevity.

The discovery4 was so surprising that it’s taken two years to be published (in Nature) because of how much additional data the outside scientists reviewing the study requested. Geneticist Bruce Yankner of Harvard Medical School, who led the research, understood their skepticism. “If you say you have a cat in your backyard, people believe you,” he said. “If you say you have a zebra, they want more evidence.”

Huda Suliman at Ending Age-Related Diseases 2019

Posted by in categories: biotech/medical, life extension

We’re continuing to release talks from Ending Age-Related Diseases 2019, our highly successful two-day conference that featured talks from leading researchers and investors, bringing them together to discuss the future of aging and rejuvenation biotechnology.

Huda Suliman of Icaria Life Sciences discussed her company’s role in the rejuvenation biotechnology ecosystem, including small molecule drug discovery and drug screening along with how her company deals with irreproducibility in the scientific literature. She explained how species differences are an issue, and she explained the differences between aging-focused and traditional medical research.

New drug forces flu virus into ‘error catastrophe,’ overwhelming it with mutations

Posted by in category: biotech/medical

Plemper says additional toxicity tests in animals have not thrown up any red flags, and the first trials of EIDD-2801 in humans are likely to start next spring. Pavia says the new drug could eventually be used in combination with other drugs to stave off resistance, a strategy already in use for HIV and hepatitis B treatments.

Poor toilet hygiene behind E. coli superbug spread

Posted by in categories: biotech/medical, food

People not washing their hands after going to the toilet, rather than undercooked meat, is behind the spread of a key strain of E. coli.

Experts looked at thousands of blood, faecal and food samples.

They found human-to-human transmission was responsible — “faecal particles from one person reaching the mouth of another”.

Heat camera at tourist attraction spots woman’s breast cancer

Posted by in categories: biotech/medical, electronics

A trip to a tourist attraction in Scotland turned out to be a life-changing moment for one woman after a thermal camera detected she had breast cancer.

Bal Gill, 41, was looking back over images from her trip to Camera Obscura and World of Illusions, in Edinburgh, when she noticed a heat patch over her breast.
