What do you name a virus that is 1,000 times larger than the flu virus, has 200 times as many genes, and 93% of those genes are previously unknown to science? The mythical Pandora’s Box seemed an appropriate inspiration, and so the genus was dubbed Pandoravirus. These extra-large viruses may have been missed in the past because of their size, and were likely thought to be bacteria. Pandoraviruses do not behave typically, and may re-open the conversation regarding viruses as a life form. More info: http://bit.ly/1bwvYuY Image via Chantal Abergel and Jean-Michel Claverie

I received a new research project in my lab today on concurrent ehrlichia infections in dogs! All the happy feels!
Steering Stem Cells with Magnets
Magnets could be a tool for directing stem cells’ healing powers to treat conditions such as heart disease or vascular disease.
By feeding stem cells tiny particles made of iron oxide, scientists at Emory and Georgia Tech can use magnets to attract the cells to a particular location in the body after intravenous injection.
The results are published online in the journal Small and will appear in an upcoming issue.

This is why they have such a problem with plastic bags. It’s because the unique structure of their esophagus makes it so that they can’t get rid of them.

the himalayan monal is a large member of the pheasant family found in parts of asia. while during the breeding season they mainly stay in pairs, in winter they form small communities and roost together. they feed on grasses, insects, seeds and berries. they are known for their vivid iridescent plumage, particularly colorful for a pheasant. x
Deep in the mud of the Mediterranean Sea, scientists have caught microscopic protists dancing to a strange beat—the beat of Earth’s magnetic fields. Now, a new study reveals how these tiny clusters of cells orient themselves along those fields: by letting magneto-sensing bacteria hitch a ride on their outer membranes.
Researchers used microscopes to examine protist-packed sediment taken from the bottom of the Mediterranean Sea near Carry-le-Rouet, France. When they placed a magnet with its north pole facing a water droplet from the sediment, the hundreds of protists inside immediately began to swim toward the droplet’s edge. When the researchers reversed the magnet so its south pole was facing the droplet, the protists fled in the other direction (above).
Microbiologists have learned how a probiotic bacterium used to treat irritable bowel syndrome can soothe gut bacterial infections caused by salmonella, paving the way for potential relief from foodborne illnesses that affect millions of people annually.
The central nervous system (CNS) in most vertebrates forms initially as a flat sheet of cells, which subsequently rolls up and fuses shut to form the hollow neural tube, which is the precursor to the CNS. The enriched apical actin in the closing neural tube (shown in green in the image) is central to cell shape changes that contribute to the rolling up process.
