Giants joust in the cold

A new giant was born recently in the coastal waters of Antarctica. A series of images captured from May through the beginning of this month by ESA`s Envisat satellite shows the subsequent duel between the new iceberg and another as it breaks free of the Ross Ice Shelf and tries to move north.

Christened C-19 by the US National Ice Centre in Maryland, the new iceberg measured 200 x 32 km, and about 200 m thick.

As seen in the accompanying animation of images acquired by Envi

Folic acid deficit increased risk of miscarriage in early pregnancy

Low levels of folic acid in plasma have been associated with an increased risk of miscarriage in a study published in Journal of the American Medical Association lately. On the other hand, no connection was found between high levels of folic acid and increased risk of miscarriage.

In the US folic acid is added to flour to prevent pregnant women from developing a deficit of folic acid. Previous studies have shown that both deficits and surpluses of folic acid can heighten the risk of miscarri

Taxol based chemotherapy increases survival by 31% in women with metastatic breast cancer

First line chemotherapy containing Taxol is an independent predictive factor for survival

New data presented for the first time today adds to existing evidence that Taxol? offers women with metastatic breast cancer (MBC) a 31% improvement in overall survival compared to standard treatment and a 33% chance of improved progression free survival, the largest improvements ever seen. The data collected from 640 patients treated in a consecutive series of studies between 1994 and 2001 als

Through a light, darkly

A British physicist has come up with a way to reveal the shifting and shining colours that form in the dark spots where light waves interfere with each other. The patterns await experimental demonstration but computer-generated images are already illuminating new aspects of light that had until now remained in the shadows.
When two waves meet their peaks and troughs interfere. If the peaks are in phase you get a higher peak as the energies of each wave add together, two troughs take away from eac

Tokamak fusion test reactor removal successfully completed

One of the world’s largest and most successful experimental fusion machines has been safely disassembled and cleared away. In September, staff at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) completed the dismantling and removal of the Tokamak Fusion Test Reactor (TFTR), which shut down in 1997 following 15 years of operation. During its experimental life, TFTR set records for fusion performance and made major contributions to the development of fusion as

Swallowing a tiny imaging capsule aids in diagnosis of obscure gastrointestinal bleeding

The use of a small wireless capsule video device to detect bleeding in the small intestine is safe, well-tolerated, and more accurate than another common diagnostic approach according to a study presented at the 67th Annual Scientific Meeting of the American College of Gastroenterology.

“The investigation of obscure gastrointestinal bleeding is often difficult due to limitations of conventional endoscopic studies in the detection of disorders in the small intestine,” said Ramona M. Lim, M.D
