Artwork of a satellite destroying space junk

Space junk demolition. Conceptual artwork of a satellite using a laser to destroy space junk. Space junk is an assortment of used rocket stages, old, dead hardware and other orbiting detritus which has been left in orbit by the hundreds of space missions since the 1950s. Destroying the junk by laser is just one idea about how to clear it. It has been estimated that there are over 20, 000 man-made objects in orbit, of which only a tiny minority are operational satellites. These objects pose a serious threat to further missions, as a collision with a delicate piece of space hardware could damage it severely. A collision with an inhabited craft could even prove fatal

Angina treatment: calcium antagonist mechanism Featured 4 Feb 2004 Print

Angina treatment: calcium antagonist mechanism

Angina treatment by calcium channel blockers. Artwork showing a calcium antagonist drug blocking membrane calcium channels in smooth muscle. This drug treats angina, hypertension and certain kinds of cardiac arrhythmia. Calcium channel blockers (green) interfere with the entry of calcium ions (orange) into smooth muscle cells via calcium channels (mauve). This impairs contraction of muscle fibres (bottom) inside the cells and causes relaxation of muscle in blood vessel walls. This improves the circulation of blood through the heart and reduces the blood pressure. The passage of nerve impulses through the heart are slowed, which helps correct certain arrhythmias
