New research into muscle contraction will give scientists a better understanding of bladder problems and pain during childbirth.

Research may provide new link between soft drinks and weight gain
A University of Cincinnati (UC) study provides new evidence that drinking large amounts of beverages containing fructose adds body fat, and might explain why sweetening with fructose could be even worse than using other sweeteners.

Hey doc, do I still need this catheter?
Millions of hospital patients could be spared the humiliation and infection risk that come with a urine-collecting catheter, a new study finds, if hospitals used a simple reminder system to prompt doctors to remove the devices after two days.

Penn researchers take a big step forward in making smaller circuits
In the race to take advantage of the amazing electric properties of nanotubes, researchers at the University of Pennsylvania developed a new method to create functional nanotube circuits.

Census of Marine Life explorers surprised by diversity, density of Arctic creatures
A historic expedition of Census of Marine Life explorers to the planet's most northern reaches has revealed a surprising density and diversity of Arctic Ocean creatures, some believed new to science.

Milk genomics and human health symposium
International experts in nutrition, genomics, bioinformatics and milk will gather to discuss genomic research related to milk during the second International Symposium on Milk Genomics and Human Health.

New software can help people make better decisions in time-stressed situations
Human teams aided by a software system can make decisions more accurately and quickly in time-stressed situations than teams of just people, according to the Penn State researchers who developed the new software.

Experts on global nursing shortage provide recommendations to stem crisis
International nurse migration experts convened on July 9, 2005 at the Rockefeller Foundation Conference Center in Bellagio, Italy to examine the causes and consequences of the global nurse shortage and to consider strategies to mitigate its negative impact on the health of people around the world.

Researchers reveal secret of key protein in brain and heart function
Brown University researchers have solved the structure of a critical piece of SAP97, a protein used to keep hearts beating and brains learning.

New understanding of cell movement may yield ways to brake cancer's spread
A Burnham Institute study has identified a fragment of a protein that senses chemicals that induce a cell to move into the right direction.

Single molecule is in driver's seat of molecular machine
The downsides of conventional molecular machines are that they are driven as an ensemble, by external light or chemistry, for example, and they are big -- made up of many molecules.

Detecting the traces of mystery matter
Using high-speed collisions between gold atoms, scientists think they have re-created one of the most mysterious forms of matter in the universe -- quark-gluon plasma.

Oceanographers work a quarter of the world away from ship they're 'on'
Being seasick is not a problem for scientists on a major expedition now under way in the middle of the Atlantic Ocean.
