Birds do it and bees do it as celebration of life. Science Daily explains how bacteria can do it – and make themselves antibiotic-resistant – by using dead cells to reproduce:

Bacteria don’t have sex as such, but they can mix their genetic material by pulling in DNA from dead bacterial cells and inserting [...]

New Scientist is not (we hope) introducing a 1950s-style horror film with their story on the giant, prehistoric virus THAT LIVES AGAIN:

Rheumatoid arthritis has long been a medical mystery – an autoimmune disease that’s triggered by who-knows-what, but that suddenly starts attacking the joints and causing chronic pain and fatigue. Well, Laboratory Equipment says some NYU researchers might just have found the culprit lurking in patients’ digestive tracts:

That’s the argument Laboratory Equipment describes some mathematical taxonomists (there’s a discipline for you) are making – claiming that some kinds of plankton are individually so small and so *weird*, they’re impossible to divide into different species:

A new mathematical theory from the Univ. of Bath is challenging one of the most basic ideas of [...]

Science, Space & Robots brings the paralysis of inhuman knowledge, as creatures tiny and writhing cast their malevolent gazes up at the electron scanning microscope.

One step closer to androids. That’s where scilogs is bringing us. Making a blood supply for bioengineered organs from scratch:

Starting off with fibroblasts…, widespread cells that provide structure and support in every organ, the team supplied four lots of DNA-targeted instructions designed to reset the cells to a more primitive state. This prompted [...]

Nature celebrates the discovery of ancient life… not from the much-ballyhooed Lake Vostok project, but a smaller lake. Still frozen for a long, long time. And definitely home to life under the Antarctic ice:

Scientists drilling into the lake have found abundant and diverse bacteria. “Lake Vida is not a nice place to [...]
