The conventional line of thinking says that women can produce only a finite number of egg cells over their lifetimes. Some researchers dispute this, but a new study suggests that it might not matter. Researchers at Massachusetts General Hospital claim they have isolated stem cells from human ovaries and used them to generate egg cells [...]

Our earliest evolutionary ancestor may have been found in the form of microscopic sponge-like organisms recently discovered inside extremely ancient African rocks. If that turns out to be so, it would displace animal life’s previous earliest known ancestor (unremarkably, another sponge-like “metazoan”) by predating it by perhaps 100 million years. Otavia antiqua could be the [...]

Bleeding out on the battlefield–far from the trauma wards and triage units that might save their lives–is a scenario that soldiers simply have to live with (and try like hell to avoid). But thanks to ananoscale breakthrough at MIT, the chances of it happening could be significantly reduced. Researchers there have created a nanoscale coating [...]

The future technology depicted in the various Star Trek TV series and films certainly holds a lot of appeal for many of us – who wouldn’t want to teleport to Hawaii, live out their fantasies on a holodeck, or enjoy some instant gourmet chow straight out of a replicator? It looks like the Star Trek [...]
Antibiotics may be permanently altering the guts of humanity

If you’re one of those people worried that the over-prescription of antibiotics is leading us toward biological calamity, you’re not going to like this. Writing in the journal Nature this week, Martin Blaser of NYU’s Langone Medical Center makes the case that antibiotics aren’t just leading to highly resistant superbugs, but that they are permanently [...]
