Giant plankton-eating fishes roamed the prehistoric seas for over 100 million years before they were wiped out in the same event that killed off the dinosaurs, new fossil evidence has shown.
A non-pathogenic bacterium is capable to trigger an autoimmune disease similar to the multiple sclerosis in the mouse, the model animal which helps to explain how human diseases work. This is an unprecedented mechanism which could explain how this terrible central nervous system disease starts up in humans.
As spring approaches and people return to outdoor activities, caution should be taken in areas of the country that are home to Loxosceles reclusa, also called the brown recluse spider. A new study found that when patients present with sudden anemia, but the cause is elusive, the brown recluse spider should be part of the differential diagnosis, at least in parts of the nation where the spider is regularly found.
A new study shows mice infected with the bacteria salmonella develop clinical signs consistent with a deadly and poorly understood human inflammatory disease, a finding that may lead to new therapies.
In a world first, the researchers have used ordinary cotton thread and sewing needles to literally stitch together the uniquely low-cost microfluidic analytical device, which is the size of a postage stamp and allows scientists to carry out chemical analyses of minute fluid samples, such as blood and urine.
The anxiety that often accompanies a chronic illness can chip away at quality of life and make patients less likely to follow their treatment plan. But regular exercise can significantly reduce symptoms of anxiety, a new study shows.
Even premature babies at 33 weeks post-conceptional age, about 2 months before term (40 gestational weeks), are capable of recognizing and distinguishing two objects of different shapes (a prism and a cylinder) with their right or left hands.
A novel compound is highly effective against the pathogenic H5N1 avian influenza virus, including some drug-resistant strains, according to new research.
Call them oil droplets with a brain or even “chemo-rats.” Scientists have developed a way to make simple oil droplets “smart” enough to navigate through a complex maze almost like a trained lab rat. The finding could have a wide range of practical implications, including helping cancer drugs to reach their target and controlling the movement of futuristic nano-machines, the scientists say.
The CREST trial that compared traditional surgery with less-invasive stenting to clear dangerously clogged carotid arteries in the neck is being called “seminal and robust.”
