Study provides new insights into how the human immune system protects against Ebola infections

Two types of human antibodies that target different parts of the Ebola virus synergize their antiviral effects by inhibiting different steps of infection, according to a study published August 23 in the open-access journal PLOS Pathogens by Philipp Ilinykh and colleagues from the University of Texas Medical Branch, Vanderbilt University, and Ragon Institute.

Scientists design biomaterial that stimulates growth of blood vessels in teeth after root canal

A root canal ranks high on most people's list of dreaded dental procedures. Although the lengthy and sometimes painful surgery relieves the agony of an infection, a root canal results in a dead tooth with no living soft tissue, or dental pulp, inside.

Microscopic insect odour detecting mechanisms discovered

Researchers at Rockefeller have used an ultra sensitive device to detect the olfactory systems of insects that help them smell out food and danger. The study titled, “Cryo-EM structure of the insect olfactory receptor Orco,” on the ion channels that form the basis of the odour detecting systems of insects was published in the latest issue of the journal Nature.

New discoveries show how protein droplets do more than keep cells’ interiors tidy

Inside cells, where DNA is packed tightly in the nucleus and rigid proteins keep intricate transport systems on track, some molecules have a simpler way of establishing order. They can self-organize, find one another in crowded spaces, and quickly coalesce into droplets - like oil in water.
