Sand grains from Maui, Hawaii. These were the first grains of sand that I examined through the microscope. I was amazed by the array of spectacular bits and pieces. The "Y" shaped glassy structure at the top is a sponge spicule, which functions as the internal skeleton of most sponges. Just to the left and down are two perfectly formed microscopic shells. Just to the right and down from the sponge spicule is a bit of brown sea urchin spine, with its intricate structural design

Staphylococcus bacteria. Most common of the 1 trillion bacteria that live on our skin. Only a few strains of this bacteria are harmful and cause staph infections or toxic shock syndrome.  Most are harmless.

Leishmaniasis is a serious parasitic disease that affects 12 million people worldwide. Like for many neglected tropical diseases that disproportionately affect poor populations, existing drugs have serious side-effects and face increasing parasite resistance. A study identifies a new drug target, and supports the conclusion that iron-dependent signals generated in the mitochondria are essential for the development of parasite stages that cause disease in humans.

✯ Blood cells, coloured scanning electron micrograph (SEM). Seen here are two red blood cells (erythrocytes, red), platelets (orange), macrophages (green), a lymphocyte (blue) and a neutrophil (yellow). Magnification: x4000 when printed at 10 centimetres wide.✯

Human red blood cells (erythrocytes) trapped in a fibrin blood clot. Platelets (not seen) are cell fragments in the blood that play an essential role in blood clotting and wound repair. Platelets serve as the body's first line of defense to prevent excessive blood loss. When an injury such as a cut is sustained, platelets change their shape (now known as activated platelets), become sticky, and build up on a vessel wall to form a plug.

Fallopian tube. Colored (SEM) of the lining of a fallopian tube (oviduct). The secretory cells (pink) secrete mucus, which protects the lining. The ciliated cells are covered in microscopic hair-like cilia (purple). These beat in wave-like motions and move the egg along the tube. Credit: Steve Gschmeissner/ Science Photo Library
