Narrated by actor Edward James Olmos, this video describes one of the body’s critical anti-cancer defences – the telomeres. These caps on the ends of our chromosomes shorten each time a cell divides and, when they become too short, trigger the cell to self-destruct. When a cell grows too rapidly, it and all of its descendants normally suffer this fate. Such growths are sometimes called “pre-cancer”. Since our stem cells need to be able to divide without this constraint in order to replace cells lost across the body, they produce the enzyme telomerase to re-extend their telomeres. Unfortunately, a small number of pre-cancerous cells manage to activate their own copies of the telomerase gene, escaping the limit on their growth. SENS Research Foundation is developing therapies to completely block telomere extension in pre-cancerous cells, ensuring the body’s existing defences can function as intended.
One of the biggest things driverless vehicles is going to do to the average person is to take away the semi driver jobs.
It’s an unfortunate fact and one that will continue to spread to other facets of the workforce, but for now we won’t have to worry, that’s a while off. Either way there’s still the first in what will hopefully be a long line of elegant driverless semi’s, and the two you’re about to see come straight from the geniuses at Audi. The first of these beautiful trucks is the street truck, designed for active use on the road. The second is their show truck, and looks to be much less practical but much cooler to be in!
Genetically modified organisms and foods are a safe way to meet the demands of a ballooning global population, the 109 laureates wrote in a letter posted online and officially unveiled at a news conference on Thursday in Washington, D.C.
The world’s top scientists say opponents of genetically modified foods are standing in the way of nutrition for people around the world.
A startup called Starry is shaking things up, attempting to provide a faster internet service that’s cheaper and hassle-free (and remarkably fast). Testing is set to begin in Boston.
Say goodbye to expensive internet coming in at slow speeds.
