Life may really have been created by a spark, one that came as a bolt from the deep blue.
Hydrothermal vents on the deep ocean floor are believed by many to be the cradle for early life. Now a team led by Ryuhei Nakamura at the University of Tokyo in Japan have uncovered evidence that such ve... Read More
The National Science Foundation has awarded $101.9 million for a range of research projects that dive into the genomes of plants to make discoveries that could be valuable for developing more sustainable and disease-resistant crops.
The Plant Genome Research Program (PGRP) grants this year ha... Read More
Could it be another nail in the coffin for the term “prokaryotes”? Patterns of inheritance are complicated, and the microbial world is no exception. Take the Archaea: since they’re small, we often assume they have more in common with bacteria than with eukaryotes. We even lump archaea and bac... Read More
It could be a breakthrough in the hunt for an "elixir of life". Organic molecules containing a heavy isotope of hydrogen seem to resist the kind of cell damage that happens with ageing. But hang on to your moisturiser for now: the effects have been demonstrated only in yeast cells.
