In the past few years we have learned to read the signals in other organic molecules that tend to survive longer than DNA and persist even in warm environments. Now, some think they could reveal how archaic humans like H. naledi evolved and interacted. Image: hape662
The Future of Lasers
There is now a new kind of scientific machine on the horizon: a trimmed down particle accelerator that is small enough to fit on a tabletop. Diminutive they may be, but these table-top accelerators are still bursting with the power and versatility. Image: milkisprotein
Bacteria: The miracle microbes that could fix planet
As unlikely as it might sound, our future health and happiness might be secured by humble bacteria that can pull carbon dioxide from the air, grow greener food and clean up pollution. Image: NIAID
