The first era of genomics started with the publication of Watson and Crick’s notable work on the description of the DNA double helix in 1953. This era lasted 50 years, until the publication of the human genome in April 2003. The second era is associated with the period between the completion of the human genome and the present day.

FeatureGraphenePress releases rarely miss an opportunity to trumpet graphene’s strength. But where does the claim that it is “200 times stronger than steel” come from? Back in 2008, a team led by James Hone at Columbia University came up with a clever way to measure graphene’s strength. Researchers draped monolayer graphene flakes extracted with Scotch tape over tiny holes in silicon, and then pressed down with the tip of an atomic force microscope until the graphene ruptured.

Editor’s summaryThe prenyl group is a hydrophobic five-carbon fragment common across a wide range of contexts in biochemistry and natural product chemistry. One extensive class of natural products of pharmaceutical interest, polycyclic polyprenylated acylphloroglucinols (PPAPs), has been the target of multiple synthetic studies, but the introduction of the prenyl groups asymmetrically has proven to be an enduring challenge. Ng et al.

AbstractPhytoplankton produce organic matter in the sunlit upper ocean, which forms particles of “marine snow” that sink and transfer carbon from the surface to the deep ocean. These particles sustain a vast carbon reservoir and are consumed to provide energy to ecosystems in the deep sea (1). Deciphering what controls carbon transfer by marine snow has been a central question in oceanography since the 1980s.
