There is currently no drug treatment for sleep apnea, a sleep breathing disorder affecting about 30 million individuals in the United States.

Researchers report that an investigational Zika vaccine was well-tolerated and stimulated potentially protective immune responses in three Phase 1 clinical trials,

Using a FIRE spectrometer, a team of astronomers have detected the most distant supermassive black hole ever observed. The black hole sits in the center of an ultrabright quasar, the light of which was emitted just 690 million years after the Big Bang. That light has taken about 13 billion years to reach us — a span of time that is nearly equal to the age of the universe.

Commonly prescribed painkillers need to be given for shorter periods of time to reduce the risk of obesity and sleep deprivation, a new study has revealed.

A team of scientists using a state-of-the-art instrument reports the discovery of a planetary-scale “tug-of-war” of life, deep Earth and the upper atmosphere that is expressed in atmospheric nitrogen.

Exposure to air pollution on city streets is enough to counter the beneficial health effects of exercise in older adults, according to new research. The findings show that short term exposure to air pollution in built up areas like London’s busy Oxford Street can prevent the positive effects on the heart and lungs that can be gained from walking.

A research team from Kiel University has now not only managed to successfully place a new class of spin-crossover molecules onto a surface, but they have also used interactions which were previously regarded as obstructive to improve the molecule's storage capacity.

Scientists recently found that bacteria that carry the colistin resistance gene mcr-1 commonly exist in human and various types of food and environmental samples collected from Hong Kong and the Chinese mainland. The prevalence of mcr-1 in our ecosystem challenges the role of colistin as the last resort antibiotic.

Cells are crowded with macromolecules, which limits the diffusion of proteins, especially in prokaryotic cells without active transport in the cytoplasm. While investigating the relationship between crowding, ionic strength and protein diffusion, biochemists made a fascinating discovery: positively charged proteins stick to the surface of ribosome complexes. This explains why most water-soluble proteins carry an overall negative charge.

One of the most revered Christian saints, St. Nicholas’ remains are held in the Basilica di San Nicola, Bari, Southern Puglia, since 1087, where they are buried in a crypt beneath a marble altar. Using a micro-sample of bone fragment, have for the first time tested one of these bones. The radiocarbon dating results pinpoint the relic’s age to the 4th century AD - the time that some historians allege that St. Nicholas died (around 343 AD). The results suggest that the bones could in principle be authentic and belong to the saint.
