Beyond our oceans: Microplastics pollute rivers and lakes too [The Conversation]

When you think of microplastic pollution, plastic debris less than five millimetres in size, you likely envision the ocean — probably because ocean gyres gained notoriety for being a microplastic soup.
But what about our lakes, rivers, forests and fields? They can be just as contaminated with microplastic debris as the oceans.

Les i-motifs : cette nouvelle forme d’ADN enfin observée dans des cellules vivantes [Sciences & Avenir - Biologie cellulaire]

Formant une sorte de "nœud" au sein de la fameuse double hélice, les "i-motifs" sont une nouvelle forme d’ADN observée pour la première fois dans des cellules humaines vivantes, d’après une publication australienne. Ils jouent un rôle crucial dans le cycle de vie de la cellule.

Ants found to use trapping technique to capture much larger prey [Phys]

Two researchers, one with Biofaction in Austria, the other with Université de Toulouse in France, report an example of ants (Azteca brevis) in Costa Rica who have developed a truly unique way of capturing prey that are much larger than they are. As Markus Schmidt and Alain Dejean describe in their paper published in the Biological Journal of the Linnean Society, the ants have found a way to take advantage of the impact a type of fungus has on trees to help them capture prey.

Fungus senses gravity using gene borrowed from bacteria [Phys]

The pin mold fungus Phycomyces blakesleeanus forms a dense forest of vertically growing fruiting bodies, but how does it know which way is "up"? New research publishing 24 April in the open access journal PLOS Biology, from Gregory Jedd’s group at the Temasek Life Sciences Laboratory, National University of Singapore, reveals that the fungi have acquired and re-modelled a gene from bacteria to help them make large gravity-sensing crystals.

Land use and pollution shift female-to-male ratios in snapping turtles [Phys]

Most of us know that our biological sex is decided by the pairing of X and Y chromosomes during conception.
However, for many wildlife species, sex of offspring is determined after fertilization and often influenced by environmental factors, such as temperature. The sex of reptiles, for example, is based on temperatures in the nest while eggs incubate.
