Cooled by an electric pulse - Nature A material has been made that turns cold at the push of a button, a feature that could be harnessed by novel cooling systems for computers. This principle, called the electrocaloric effect, has been known since the 1960s, but it had seemed too weak an effect to be of much use. The Cambridge team has now found a ceramic material that shows what they call a giant electrocaloric effect; it's more than 100 times larger that seen previously. The material is actually a variant of a well-known one, called lead zirconate titanate, or PZT. This hard, crystalline solid is piezoelectric: squeezing it creates an electric field inside it. This makes PZT useful for inter-converting sound and electrical energy, as is done in some microphone and ultrasound technologies. |

Living traditions: An exhibition shows how western medicine is not the only choice - BBC Ever wondered what an African medicine man might carry in his bag in the 19th Century? For the record, it is thirty animal vertebrae, two pebbles, one hoof, two pieces of carved bone and one nut-shell. Or has the appearance of a Sri Lankan syringe in the 16th Century caused a few moments of contemplation? 'Western' medicine' is not the only widely used medical tradition. The exhibition discusses the traditions and explores the fact that they are still very much alive and continuing to grow. |

New satellite data show Antarctic ice loss - MSNBC Joining the growing list of places on this planet that are melting, Antarctica is losing about 36 cubic miles (150 cubic kilometers) of ice every year, scientists reported Thursday. The south polar region holds 90 percent of Earths ice and 70 percent of the total fresh water on the planet, so any significant pace of melting there is important and could contribute to an already rising sea. "This is the first study to indicate the total mass balance of the Antarctic ice sheet is in significant decline," said Isabella Velicogna of the University of Colorado at Boulder. Other studies have documented rapid melting, unprecedented in modern times. |
