Lead exposure plus high blood pressure may impair mental ability
Exposure to lead in early childhood and adolescence may contribute to hypertension-related decline that can impair a person's cognitive abilities, according to a new study presented at the 2005 American Heart Association's High Blood Pressure Research meeting. view more (2005-09-26)
Touching outlawed by hands-free monitor - Photon02
A Loughborough University research team, led by Professor Peter Smith and Vincent Crabtree, has developed a way of monitoring the blood flowing in human body tissue without actually touching the skin. This hands-free technique could one day be used to assess patients during surgery and monitor the healing of wounds or burns. Other applications... view more... (2002-08-30)

Maximum Comfort for Patients
A multiple-parameter medical network with wireless sensors for the measurement of vital body functions will be exhibited by Fraunhofer Institute for Integrated Circuits IIS at the CeBIT 2004. It is comfortable and convenient to wear - the wireless sensor wristband of Fraunhofer IIS for the measurement of the pulse waves and the oxygen saturation... view more... (2004-03-05)
X-CELLENT News For BP Management
New trial findings, presented at last week's European Society of Hypertension meeting in Paris, have provided a clearer perspective on optimum treatment of patients with isolated systolic hypertension (ISH). Results from the X-CELLENT study showed that the thiazide-like diuretic indapamide SR offers benefits over both the calcium channel blocker... view more... (2004-06-25)
Light is shed on new fibre's potential to change technology
Photonic crystal fibre's ability to create broad spectra of light, which will be the basis for important developments in technology, has been explained for the first time in an article in the leading science journal Nature-Photonics. view more (2007-12-11)
U of MN researchers use human embryonic stem cells to kill cancer cells
For the first time, stem cell researchers at the University of Minnesota have coaxed human embryonic stem cells to create cancer-killing cells in the laboratory, paving the way for future treatments for various types of cancers (or tumors). view more (2005-10-12)
Rising tides intensify non-volcanic tremor in Earth's crust
For more than a decade geoscientists have detected what amount to ultra-slow-motion earthquakes under Western Washington and British Columbia on a regular basis, about every 14 months. view more (2007-11-26)
Laser Blasts Viruses in Blood
A father-son research team working from separate laboratory benches across the country has discovered a new use for lasers - zapping viruses out of blood. The technique, which holds promise for disinfecting blood for transfusions, uses a low-power laser beam with a pulse lasting just fractions of a second. view more (2007-09-05)
New technique measures ultrashort laser pulses at focus
Lasers that emit ultrashort pulses of light are used for numerous applications including micromachining, microscopy, laser eye surgery, spectroscopy and controlling chemical reactions. But the quality of the results is limited by distortions caused by lenses and other optical components that are part of the experimental instrumentation. view more (2008-05-09)
Engineering all things bright and beautiful
The human and inspirational aspects of engineering are highlighted in a new series of posters being received this week by school science departments around the UK. The poster series, Shine, Sniff, Wave, Pulse, has been devised and funded by the School of Electronics and Computer Science (ECS) at the University of Southampton, and uses arresting... view more...

Hopes raised for effectiveness of multiple sclerosis drug
Discovery of the mechanism of a drug being tested for the treatment of multiple sclerosis (MS) has revealed that it's not only more effective than first thought, but might also help in the management of other autoimmune diseases, organ transplant rejection and even cancer. view more (2006-03-29)
New theory for mass extinctions
A new theory on just what causes Earth's worst mass extinctions may help settle the endless scientific dust-up on the matter. view more (2006-10-25)
Cellular pathway yields potential new weapon in vaccine arsenal
When a cell has to destroy any of its organelles or protein aggregates, it envelopes them in a membrane, forming an autophagosome, and then moves them to another compartment, the lysosome, for digestion. Two years ago, Rockefeller University assistant professor Christian Münz showed that this process, called autophagy, sensitizes cells for... view more... (2006-12-27)
Lasers Generate Underwater Sound
Scientists at the Naval Research Laboratory are developing a new technology for use in underwater acoustics. The new technology uses flashes of laser light to remotely create underwater sound. view more (2009-09-08)
Killer bees may increase food supplies for native bees
Aggressive African bees were accidentally released in Brazil in 1957. As "killer bees" spread northward, David Roubik, staff scientist at the Smithsonian Tropical Research Institute, began a 17-year study that revealed that Africanized bees caused less damage to native bees than changes in the weather and may have increased the... view more...

Traces of nanobubbles determine nanoboiling
Using a microscope and some extreme "snapshot" photography with shutter speeds only a few nanoseconds long, researchers from the National Institute of Standards and Technology (NIST) and Cornell University have uncovered the traces of ephemeral "nanobubbles" formed in boiling water on a microheater. view more (2007-04-02)
Research shows fat fuels inflammation killer
New research by the University of Warwick's Warwick Medical School shows that the biggest health threat to fat and obese people isn't the fat itself but the fact that the fat fuels a killer inflammation response in people. view more (2006-03-09)
Killer electrons in space are now less mysterious
A rare, timely conjunction of ground-based instrumentation and a dozen satellites has helped scientists better understand how electrons in space can turn into 'killers'. ESA's Cluster constellation has contributed crucially to the finding. view more (2007-07-27)
