Electron cryo-microscopy has been used to determine the structure of Chikungunya virus-like particles and to provide new insights into their interactions with four different antibodies.

The ability of an enzyme called XPD helicase to unwind the double helix is influenced by the DNA sequence and the availability of energy.

The eye produces a protein that inhibits the growth of blood vessels in the deep retina, which includes the photoreceptor layer, and disruption of this process can lead to blindness.

Quantification of all the major on- and off-pathway kinetic parameters in the transcription elongation cycle reveals that RNA polymerase II translocates slowly in a linear, non-branched Brownian ratchet mechanism.

Melainabacteria, a candidate phylum related to Cyanobacteria, has been identified in gut and sediment samples by genomic analysis.

Lipids with a propensity to form nonbilayer structures must be present for the last step of membrane fusion to take place.

Cooperation enables burying beetles to outcompete flies and adapt to a wider range of temperatures as thermal generalists.

Novel virus-host systems yield insights into how Lepidopterans (moths and butterflies) combat RNA virus infection and reveal that poxvirus A51R proteins can suppress the host's immune system and stabilize microtubules in host cells.

Eukaryotic translation elongation factor 1A1 controls the process of heat shock response, from transcriptional activation of the HSP70 gene, to HSP70 mRNA stabilization, nuclear export, and translation.

Understanding where future Ebola virus outbreaks may start and the changing nature of the populations living in these places is of critical importance in helping to prepare for future outbreaks.
