2021 BABY LETS GO

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

Hitchhiking bacteria might help their host navigate via magnetic fields

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).

My favorite Female Scientist by Drziggystardust

Mathematician, philosopher, astronomer- Mostly known for her work in mathematics because she is the first well documented woman in the field. Her life and work were so important that many scholars agree that her brutal murder by religious zealots marks the end of the Classical Antiquity era, at the very least her death marked the downfall of intellectual life in Alexandria.

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 false-coloured scanning electron micrograph shows connective tissue removed from a human knee during arthroscopic surgery. Individual fibres of collagen can be distinguished and have been highlighted by the creator using a variety of colours. The horizontal field width of the image is 16 microns.
