To be able to detect gravitation waves in space, physicist have to measure truly minimal displacements: ten billion times smaller than the size of an atom. An improved superconducting sensor is a suitable candidate for this job, Martin Podt of the University of Twente now states in his PhD thesis. He has improved the sensitivity of a so-called ‘SQUID’ in way that it can be combined with a large ball-shaped gravitation detector. Podt succeeds in this by improving the sensitivity. He integrates the sen

A dramatic increase in deformed frogs and other amphibians is being caused by a range of environmental factors, all of which ultimately can be linked to human impacts on habitat, but the primary cause of many of the deformities is an epidemic of a key parasite.

These findings are the results of eight years of research by scientists around the world, and are presented in the February issue of Scientific American by researchers from Oregon State University and the University of Wisconsin.

A rare dolphin species known for assisting fishermen by driving fish into their nets may soon disappear from the great Asian river for which the animals are named. According to a recent scientific survey by the Wildlife Conservation Society (WCS) and its partners, the Irrawaddy dolphin may vanish from the Ayeyarwady River (formerly Irrawaddy) without efforts to protect these aquatic mammals from human activities along the river.

A research team with members from WCS, WDCS (the Whale and Dol

Simple communication technique may improve health outcomes among diabetes patients, but is underused by physicians

Diabetes management may improve when physicians use an interactive communication technique with patients. Unfortunately, physicians underuse this simple strategy, according to a new study, which appears in the January 13, 2003 issue of The Archives of Internal Medicine.

Prior research has shown that patients fail to recall or comprehend as much as half of what t

Scientists who built and will control the instruments to investigate plasma changes around a comet describe their contribution to the ten year long mission at a pre-launch press briefing in London.

While the actual launch date for the European Space Agency’s Rosetta mission has yet to be confirmed, the scientists, engineers and technicians behind the plasma-detecting instruments on board the spacecraft are all ready to begin the journey to comet Wirtanen they hope will return a r

Expanding the genetic code: the world’s first truly unnatural organism
From time immemorial, every living thing has shared the same basic set of building blocks – 20 amino acids from which all proteins are made.

That is, until now: A group of scientists say they have, for the first time, created an organism that can produce a 21st amino acid and incorporate it into proteins completely on its own. The research should help probe some of the central questions of evolutionary theory.
