The otherworldly beauty of microscopic organisms
Marine diatoms are one of the smallest creatures on Earth. UK-based biologist Klaus Kemp and filmographer Matthew Killip teamed up to showcase these minuscule organisms’ diverse beauty.
Diatoms are single-celled organisms found in oceans all over the world. There are estimated to be 100,000 species of these micron-sized creatures in existence, and they play a crucial role as one of the main food sources for marine organisms, including fish, molluscs and tunicates, such as sea squirts.
Once you get them under the microscope, the diatoms will reveal the incredible glass shells that contain their tiny bodies. During the Victorian era - the second half of the 19th century - scientists would pop them under their microscopes and lay them out in complex and beautiful arrangements, and UK-based biologist Klaus Kemp is one of the last remaining scientists on Earth to keep the practice alive.
Filmographer Matthew Killip made a documentary about Kemp, as the master of diatom art, and these stunning images were the result. Killip explains how the film came to be over at Neatorama:

Strong Solar Flares This Weekend A Big Double Wammy
by Laura Geggel
Two powerful solar storms arriving at Earth today have captured the public’s attention for their potential to spark amazing auroras, but scientists say there’s another reason to watch. The solar double whammy is actually somewhat rare.
The particles from the two flares could interact as they head toward Earth, and researchers at the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center said they are monitoring the situation.
The sun unleashed a medium-sized flare on Monday (Sept. 8) followed by a second, larger flare, called an Earth-directed X-class flare, on Wednesday (Sept. 10). Both are from the same active sunspot region (Active Region 2158) and are directed at Earth, said Thomas Berger, director of the Space Weather Prediction Center, during a news conference yesterday (Sept. 11, 2014)…

From Daily Anatomy"Incredibly beautiful micrograph of blood clotting""This awesome picture is a coloured scanning electron micrograph of human red blood cells (erythrocytes, red) and platelets (thrombocyte, white) forming a blood clot. Clots are formed in response to cardiovascular disease or injuries to blood vessels. Platelets secrete chemicals that promote the accumulation of fibrin (not seen) and other blood components required for clot formation."

This year’s Longitude Prize is focused on the growing problem of antibiotic resistant bacteria. They’ve put together a nice image, shown here, which showcases what they term ‘the ten most dangerous antibiotic resistant bacteria’. You can read more detail on each of them here:http://www.nesta.org.uk/news/antibiotic-resistant-bacteria
The prize offers a £10 million prize fund for the development of a cheap, accurate, and easy to use bacterial infection test kit, which will allow doctors to prescribe the correct antibiotics at the correct time for patients, to try to help minimise the development of antibiotic resistance.

Today’s graphic takes a look at some of the different classes of antibiotics, and how they act to combat bacterial infections.

Synthetic Cells Move On Their Own
What look like animated illustrations that could easily spring from a child’s imagination are actually newly unveiled artificial cells under a microscope.
Biophysicists at Germany’s Technical University of Munich along with an international team developed simple self-propelled biomachines in a quest to create cell models that display biomechanical functions.
The researchers say their work represents the first time a movable cytoskeleton membrane has been fabricated.
lightning illuminates an ash cloud that extends ten kilometres high in this june 5, 2011 eruption of puyehue volcano, near osorno in southern chile. known as a dirty thunderstorm, this phenomenon is yet to be explained by science, as the source of the lightning (or the specific mechanism by which particles of differing charges are separated in the ash cloud) continues to be debated.
Behold a few wonders of the cosmos: From top to bottom are galaxies M101, M81, Centaurus A, and M51. The images are a collaboration combining data from amateur astronomers and NASA mission archives. X-rays from Chandra are purple, infrared data from Spitzer are red, and the optical data are red, green, and blue. (Chandra X-ray Observatory)
