Longer telomeres protect against diseases of aging: A tale of mice and men

Scientists at the Gladstone Institutes discovered a key mechanism that protects mice from developing a human disease of aging, and begins to explain the wide spectrum of disease severity often seen in humans. Both aspects center on the critical role of telomeres, protective caps on the ends of chromosomes that erode with age.


Scientists turn mammalian cells into complex biocomputers | Science

Computer hardware is getting a softer side. A research team has come up with a way of genetically engineering the DNA of mammalian cells to carry out complex computations, in effect turning the cells into biocomputers. The group hasn’t put those modified cells to work in useful ways yet, but down the road researchers hope the new programming techniques will help improve everything from cancer therapy to on-demand tissues that can replace worn-out body parts.


Scientists discover mechanism that causes cancer cells to self-destruct

Many cancer patients struggle with the adverse effects of chemotherapy, still the most prescribed cancer treatment. For patients with pancreatic cancer and other aggressive cancers, the forecast is more grim: there is no known effective therapy.


It's happening: Scientists can now reverse DNA ageing in mice

Researchers have identified a cellular mechanism that allows them to reverse ageing in mouse DNA and protect it from future damage.



They've shown that by giving a particular compound to older mice, they can activate the DNA repair process and not only protect against future damage, but repair the existing effects of ageing. And they're ready to start testing in humans within six months.


Scientists have turned spinach into beating human heart tissue

Researchers have successfully used spinach leaves to build functioning human heart tissue, complete with veins that can transport blood.



To tackle a chronic shortage of donor organs, scientists have been working on growing various tissues and even whole organs in the lab. But culturing a bunch of cells is only part of the solution - they simply won't thrive...

Strange life has been found trapped inside these giant cave crystals

Strange microbes have been found inside the massive, subterranean crystals of Mexico's Naica Mine, and researchers suspect they've been living there for up to 50,000 years.


Scientists have figured out how our brains sharpen our memories while we sleep

We all know that if we want what we've studied during the day to stick, it's best to get a good night's sleep. And while scientists have long understood that our memories rely on connections being built between neurons in our brains, it's not been clear how sleep actually helps to consolidate that information.



Now, two new studies have found biological evidence that expains the age-old wisdom that if we want to remember, we need to sleep to forget.


Bill Nye: Evolution Denial Hurts Innovation in Science and Technology - Video

Bill Nye:  Evolution is the fundamental idea in all of life science. So if we raise a generation of science students who don’t understand the main idea in biology they’re going to be incompletely educated students and this is going to be trouble for the United States because the United States keeps in the game economically by innovating – having new ideas, new products, new ways of doing things. That’s what the United States produces and brings to the world. And if we raise a significant fraction of our students who don’t understand...
