People have been talking about terraforming and colonizing Mars since the beginning of space travel, and in the past few years that ambition seems to have gone mainstream. But if we want to conquer the “final frontier” of space, we must first confront that other final frontier. Because, as it turns out, the problem with…

The researchers bound the kind of siRNA found in Huntington’s disease with a complementary strand from another degenerative disorder, myotonic dystrophy, to create a hybrid duplex, then put this inside nanoparticles that were quickly gobbled up by cancer cells in culture. All varieties of cancer tested–ovarian, lung, liver, melanoma, and several more–stopped growing within a…

(Continued from part I) Most people who’ve meet cancer on the battlefield of treatment, doctors or patients, come away with the impression of a robust and formidable foe that can only be defeated with the most terrible weapons. But this impression is somewhat misleading. The cancers that come to our attention are selected for being…

A menacing shadow looms large over the body. Lessons we’ve learned from the eternal struggle of organism against cell are etched into the farthest corners of the genome, patches on top of patches, shoring up our weaknesses for the next time the conflict erupts. And yet, even with a standing army dedicated to repairing DNA,…

What good is a longer life if you have to spend half of it keeping up with the news? Ditch those endlessly scrolling feeds, and instead join us every other week for a concentrated dose of the most exciting developments in the field of geroscience. Here’s the recap: Naked mole rats really do age better,…

Someday soon we may be able to replace tissues or entire organs with those grown from a patients’ own stem cells… but just how soon? What challenges do stem cell therapies face on the path of development, as they progress from the lab to the commercial world? James Peyer, investor and former stem cell biologist, answers below…

We know you want to keep up with the relentless march of progress, but sometimes it’s just too relentless. So why not forget all those endlessly scrolling feeds, and instead join us for a bi-weekly concentrated dose of all the most exciting developments in the field of geroscience? Here’s what’s happened in the last two weeks:…

Imagine a physiological love triangle: in one corner, a force with the weight of millions of years of evolutionary programming trained on preventing runaway replication; in the other, the set of epigenetic regulators that must maintain the ability of stem cells to churn out whatever kind of cell they need to. At first glance, the…

It’s looking increasingly likely that our little bacterial buddies have a major influence on neurodegenerative disease, from producing extra amyloid, to regulating inflammation, to generating free radicals. In mouse models of Alzheimer’s disease, a protein complex that forms part of the nervous system’s innate immune system binds to toxic amyloid-beta, promoting the formation of plaques.

At its most dramatic, oxidative stress can rend DNA in two and predispose cells to mutations that ultimately result in cancer. But the less bombastic effects of reactive oxygen molecules are no less damaging, as they likely play a central role in the world’s number one killer, vascular disease, causing stroke and heart attack among
