Fossils Document the Hour After the Meteor Hit | Portside

The beginning of the end started with violent shaking that raised giant waves in the waters of an inland sea in what is now North Dakota. Then, tiny glass beads began to fall like birdshot from the heavens. The rain of glass was so heavy it may have set fire to much of the vegetation on land. In the water, fish struggled to breathe as the beads clogged their gills.

The giant jellyfish genome and the evolution of hunting – On Biology

Despite their seemingly simple appearance, jellyfish might help us understand how complex animal life evolved over hundreds of millions of years. In this blog, the authors of a new paper in BMC Biology explain what they found from the genome of the giant Nomura’s jellyfish.

Seeds inherit memories from their mother: Maternal and environmental control of seed dormancy is carried out through novel epigenetic mechanisms — ScienceDaily

Seeds remain in a dormant state as long as environmental conditions are not ideal for germination. The depth of this sleep is inherited from their mother. Researchers reveal how this maternal imprint is transmitted through fragments of ‘interfering’ RNAs, which inactivate genes, and that a similar mechanism enables to transmit another imprint, that of the temperatures present during the development of the seed. This mechanism allows the seed to optimize the timing of its germination.
