Black Silicon: This electron micrograph shows the pattern of cones left by SiOnyx’s femtosecond laser pulse. Shining an exceptionally powerful laser light — briefly matching the energy produced by the sun falling on the surface of the entire earth — on a regular silicon wafer (that is used for manufacturing semiconductors), also applying sulfur hexafluoride, a gas used by the semiconductor industry to make etchings for circuits, results in a silicon wafer that looks black to the naked eye. But when Dr. Mazur (the originator of this idea) and his researchers examined the material with an electron microscope, they discovered that the surface was covered with a forest of ultra-tiny spikes.

This is because the particles - and those within them - are so smooth: they are artificial and have virtually no texture. The image really shows what technology can do in targeting drugs to specific purposes. This system is designed to delay the release of the drug that is contained in the smaller particles until it reaches the large intestine, where it will treat inflammatory bowel disease. The synthetic polymers used to coat a drug, either to target the release of the drug in a specific part of the digestive tract or to allow the drug to be released slowly. Polymers play an important role in reducing side-effects of drugs, as well as the number of times a patient needs to take a medication. Scanning electron micrograph images are taken in black and white and are coloured later. The orange spheres contain the drug and the encapsulating co-polymers are coloured blue.

This image shows sperm and an egg (or ovum) at the moment of conception by in vitro fertilisation (IVF). The egg is surrounded by protective cumulus cells around the outside surface, coloured yellow. The sperm need to penetrate the membrane surrounding the egg, called the zona pellucida, if successful fertilisation is to occur. Light micrograph.

This image shows capillaries, or small blood vessels, which act as the connective network between arteries and veins. They are often found as large networks supplying organs with oxygen and other nutrients, and removing carbon dioxide. Light micrograph.

Oldest preserved spider and web trapped in amber, discovered on a beach in Sussex, England. […]found the rare amber fossil in December, and have now confirmed that it contains remnants of spider silk spun roughly 140 million years ago by an ancestor of modern orb-weaving spiders. After slicing the amber into thin sections and examining each piece under a high-powered microscope, the researchers discovered that the ancient silk threads share several features common to modern spider webs, including droplets of sticky glue used to hold the web together and capture prey. - Arunn

Ice spikes are an example of the differential freezing phenomenon and form much like volcano lava ejected out and froze on the way. Since ice expands as it freezes, the ice freezing below the surface starts to push water up through the hole in the surface ice (see diagram). If the conditions are just right, then water will be forced out of the hole in the ice and it will freeze into an ice spike, a bit like lava pouring out of a hole in the ground to makes a volcano. But water does not flow down the sides of a thin spike, so in that way it is different from a volcano. Rather, the water freezes around the rim of the tube, and thus adds to its length. The spike can continue growing taller until all the water freezes, cutting off the supply, or until the tube freezes shut. The tallest spike we’ve seen growing in an ordinary ice cube tray was 56mm (2.2in) long. - Arunn
