Infection by the Zika virus diverts a key protein necessary for neural cell division in the developing human fetus, thereby causing the birth defect microcephaly, a team of Yale scientists reported Aug. 24 in the journal Cell Reports.

96 percent of marine species, and 70 percent of terrestrial life died off in the Permian-Triassic extinction event, as geologists know it. It is also known as The Great Dying Event for obvious reasons.

Atomic resolution studies of two common calcium channel blockers, one that treats irregular heart beats, and another that controls high blood pressure and angina
An atomic level analysis has revealed how two classes of calcium channel blockers, widely prescribed for heart disease patients, produce separate therapeutic effects through their actions at different sites on the calcium channel molecule.

This is an illustration of warbler.
For decades, conservationists have considered blue-winged warblers to be a threat to golden-winged warblers, a species being considered for federal Endangered Species protection. Blue-winged warbler populations have declined 66 percent since 1968, according to the North American Breeding Bird Survey.

This is a fossil ptilodactyline beetle found in amber from Mexico. The black arrow points to pollinia attached to the beetle's mouthparts.
When most people hear the word "pollinator," they think of bees and butterflies. However, certain beetles are known to pollinate plants as well, and new fossil evidence indicates that they were doing so 20 million years ago.

Squinting won't help you spot the fish in this photo. These snub-nosed darts blend seamlessly into their watery surroundings with help from their silvery reflective skin.
In a matchup of animal superpowers, a clever form of camouflage might beat super sight -- at least in the ocean.

A single thymic epithelial cell (red) in contact with developing T cells (white).
Researchers at the universities of Basel and Oxford have for the first time identified all genes regulated by the protein Foxn1. The results show that Foxn1 not only plays a crucial role in development of the thymus in the embryo, but it also regulates vital functions in the developed, postnatal organ. The decryption of the protein's functions is important in the understanding and treatment of autoimmune diseases, vaccination responses in old age and defense against tumor cells. The study was published in the journal Nature Immunology.

The just-discovered disease is a rare and sometimes lethal inflammatory disease that causes fever, skin rashes, diarrhea and joint pain in young children.
National Institutes of Health researchers have discovered a rare and sometimes lethal inflammatory disease - otulipenia - that primarily affects young children. They have also identified anti-inflammatory treatments that ease some of the patients' symptoms: fever, skin rashes, diarrhea, joint pain and overall failure to grow or thrive.

In a new study, Yale researchers demonstrate Zika virus infection of cells derived from human placentas. The research provides insight into how Zika virus may be transmitted from expectant mother to fetus, resulting in infection of the fetal brain.

Protective telomeres are augmented by freely diffusing telomerase.
As the rope of a chromosomes replicates, it frays at the ends. No problem: A chromosome's ends have extra twine so that fraying doesn't reach into the body of the rope where the important information resides. This extra twine is called a "telomere". Over time and across replications, this telomere twine breaks down until the chromosome loses its protective ends and this "fraying" reaches into the rope, wrecking the chromosome and resulting in the death of the cell.
