Chemical engineers discover new way to control particle motion potentially aiding micro- and nano-fluid systems for drug delivery, sensors, more
Chemical engineers at The University of Texas at Austin have discovered a new way to control the motion of fluid particles through tiny channels, potentially aiding the development of micro- and nano-scale technologies such as drug delivery devices, chemical and biological sensors, and components... view more (2008-03-18)

Preliminary Study Suggests Endomitriosis Could Contribute To Infertility
Authors of a research letter in this week's issue of THE LANCET provide preliminary evidence which suggests that the peritoneal fluid of women with endometriosis may play a significant role in reducing fertility. Endometriosis and infertility are known to be associated, but it is not known whether... view more (2002-10-16)

Fluid Dynamics Works on Nanoscale in Real World
In 2000, Georgia Tech researchers showed that fluid dynamics theory could be modified to work on the nanoscale, albeit in a vacuum. Now, seven years later they've shown that it can be modified to work in the real world, too - that is, outside of a vacuum. The results appear in the February 9 issue... view more (2007-02-26)

Using contrast enhanced sonography improves diagnosis of liver and spleen injuries
Contrast-enhanced sonography shows liver and spleen injuries better than non-contrast enhanced sonography.   view more (2006-10-02)

Carbon nanotube membranes allow super-fast fluid flow
Membranes composed of manmade carbon nanotubes permit a fluid flow nearly 10,000 to 100,000 times faster than conventional fluid flow theory would predict because of the nanotubes' nearly friction-free surface.   view more (2005-11-04)

Medicalising sex damages relationships
Overly medical approaches to sex ignore the social and interpersonal dynamics of relationships, argue researchers in this week's BMJ. The medicalisation of sex has resulted in surgery and drugs being used to enhance sexual pleasure, write Graham Hart and Kaye Wellings. Viagra (sildenafil citrate)... view more (2002-04-10)

Engineering the world's fastest swimsuit
A highly specialised computer modelling technique developed at The University of Nottingham has been instrumental in the design of a revolutionary new swimsuit which is now being hailed as the fastest in the world.   view more (2008-02-29)

Microtubule protein interactions visualized en masse
In a new study published online in the open access journal PLoS Biology, Philipp Niethammer, Eric Karsenti, and colleagues investigate the regulation of microtubule dynamics via application of their new method, called visual immunoprecipitation (VIP), which enables simultaneous visualization of... view more (2007-01-16)

MRS shows promise as noninvasive means to determine fetal lung maturity
MR spectroscopy (MRS) of choline levels shows promise as a marker of fetal lung maturity, according to a recent study conducted by researchers at the University of California-San Francisco.   view more (2007-05-07)

New proteomic method to detect inflammation in amniotic fluid
A score that measures the proteomic profile of amniotic fluid may predict inflammation before delivery. Researchers from Yale University, led by Catalin Buhimschi, have previously identified a set of four protein markers that were closely associated with inflammation in the amniotic fluid.   view more (2007-01-16)

The Mediterranean connection: ecological effects of El Ni'±o in the Northern hemisphere
The North Atlantic Oscillation (NAO) and the El Ni'±o/Southern Oscillation (ENSO) are being increasingly acknowledged as major climatic sources of ecological variability. However, studies linking ecological processes to those oscillations have been conducted in geographic regions close to their... view more (2004-06-10)

New developments in assessing fluid flows
Scientists at Oxford University are developing a new Doppler Global Velocimetry (DGV) technique that will enable three-dimensional fluid velocity fields to be imaged reliably and accurately. Over the last twenty years, a number of techniques have been explored to enable clear imaging of fluid... view more (2002-07-03)

Sporty Sperm: A Stiff One Gets the Job Done More Quickly
A scientist who studies the phsyics of sperm "as a hobby" is challenging the current understanding of how sperm swim towards an egg. At the Society for Experimental Biology conference today Dr Christopher Lowe will present the results of his modelling of a sperm`s tail, suggesting we may need to... view more (2002-04-10)

Discovery sheds new light on cause of earthquakes
Research at the University of Liverpool into a large fault zone in the Atacama Desert in northern Chile has produced new insight into how fluid pressure can cause earthquakes.   view more (2006-12-14)

Preterm birth risk quickly and accurately detected with proteomic profiling
By profiling specific proteins in amniotic fluid for inflammation, researchers at Yale School of Medicine can quickly and accurately detect potentially dangerous infections in pregnant women, and also predict the possibility of premature birth.   view more (2006-02-03)

Scientists discover basic defect in cystic fibrosis airway glands
Scientists at Stanford University have determined that the buildup of sticky mucus found in cystic fibrosis is caused by a loss in the epithelial cell's ability to secrete fluid.   view more (2006-03-20)

'Virtual autopsy' helps identify drowning as cause of death
"Virtual autopsy" performed with multidetector computed tomography (MDCT) can aid forensics teams in determining if a person has drowned, according to a study published in the June issue of Radiology.   view more (2007-05-29)

Telling axons where to go - and grow
In a recent study, Dr. Ingolf Bach and colleagues from the University of Massachusetts Medical School, Worcester and the University of Hamburg (Germany) describe a novel role for the ubiquitin/proteosome protein degradation pathway in the regulation of local actin dynamics in neurons.   view more (2005-10-03)

Fluid displacement from legs to neck can lead to obstructive sleep apnea
When a person lies down, a small amount of fluid displaced from the legs to the base of the neck can narrow soft tissue around the throat and increase airflow resistance in the pharynx by more than 100 percent, predisposing the person to obstructive sleep apnea.   view more (2006-12-18)

Floating lovers count too — in the health of eagle populations
In a paper from the November issue of The American Naturalist, Vincenzo Penteriani, Fermín Otalora, and Miguel Ferrer, researchers at the Estación Biológica de Doñana (Consejo Superior de Investigaciones Científicas, Spain), focus on the forgotten and invisible side of animal populations-the... view more (2006-11-02)

Scientists find potential stem cells in amniotic fluid - a new source?
Research by Austrian geneticists has raised the possibility that stem cells[1] could be isolated from amniotic fluid - the protective 'bath water' that surrounds the unborn baby. Geneticist Professor Markus Hengstschl'¤ger and his team at the University of Vienna have isolated a subgroup of cells... view more (2003-06-27)

Prematurity more accurately predicted by advances in proteomic technology

EARLY PROMISE OF NEW TECHNIQUE TO IDENTIFY BREAST CANCER
The analysis of breast-duct fluid, collected through ductal lavage (washing), could be a novel method for detecting breast-cancer cells when used in conjunction with mammography screening, conclude authors of a fast-track research letter in this week's issue of THE LANCET. If detected early, breast... view more (2001-04-25)

Local interventions have little effect on metapopulation stability
