The day LISA Pathfinder hung in the balance
At the core of ESA's LISA Pathfinder mission sit two small hearts. Each is a cube, just 5 centimetres across. Together they will allow LISA Pathfinder to lay the foundations for future space-based measurements that investigate the very core of Einstein's General Relativity. view more (2006-10-12)
Go Speed Racer! Revving up the world's fastest nanomotors
In a "major step" toward a practical energy source for powering tomorrow's nanomachines, researchers in Arizona report development of a new generation of sub-microscopic nanomotors that are up to 10 times more powerful than existing motors. Their study is scheduled for the May 27 issue of ACS Nano, a monthly journal. view more (2008-05-01)
Making Purer Rings For Pure Lovers
By using powdered metals, produced by passing molten gold, silver or platinum through a high powered jet, manufacturers will be able reduce the amount of impurities found in the ring. These impurities are picked up in conventionally produced rings as they are punched from a sheet of metal and extensively rolled into shape. The new technique also... view more... (1999-02-10)
Pushing the limits of hard disk storage
Just how much data can we cram onto a hard disk? In a paper appearing online today in Physical Review Letters, EPFL (Ecole Polytechnique Federale de Lausanne) Professor Harald Brune and his colleagues report what they believe to be the ultimate density limit of magnetic recording. view more (2005-10-10)
New Technology Could Improve Breast Cancer Detection
Teams of radiologists, scientists and radiographers from The University of Aberdeen, The University of Manchester and The South Manchester University Hospitals Trust will be using the R2 Technology ImageChecker to help detect potentially cancerous areas on mammograms. The ImageChecker helps radiologists & radiographers in a similar manner to a... view more... (2003-09-16)
Letter published in Lancet re-confirms levodopa as 'gold standard' therapy for Parkinson's Disease
Letter published in Lancet re-confirms levodopa as 'gold standard' therapy for Parkinson's Disease Use of entacapone with levodopa significantly enhances symptom control Basel, August 19 2002 - Since the late 1960s levodopa has remained the most widely used treatment for Parkinson's disease. While originally hailed as a 'miracle' drug, questions... view more... (2002-08-19)
A New Family of Molecules for Self-Assembly: The Carboranes
To be useful in real-world applications, a self-assembled monolayer (SAM) of molecules on a surface must have a stable and controllable geometry. Researchers at Penn State and the Sigma-Aldrich company have found a way to control geometry and stability by making SAMs out of different carboranethiol isomers, which are cage-like molecules. view more (2009-03-26)
Experts debate role of stenting, bypass surgery in left main coronary artery disease
Coronary artery bypass surgery has been the preferred treatment for patients with a blockage in the left main coronary artery, the conduit that supplies blood to about two-thirds of the heart. view more (2007-05-14)
PSA screening may be biased against obese men, leading to more aggressive cancers
Testing men for elevated levels of prostate-specific antigen (PSA) in the blood -- the gold standard screening test for prostate cancer -- may be biased against obese men, whose PSA levels tend to be deceptively low. view more (2008-08-11)
NIST membrane model may unlock secrets of early-stage Alzheimer's
Researchers at the National Institute of Standards and Technology (NIST) and three collaborating institutions are using a new laboratory model of the membrane surrounding neurons in the brain to study how a protein long suspected of a role in early-stage Alzheimer's disease actually impairs a neuron's structure and function. view more (2008-07-24)
Taxol bristle ball: a wrench in the works for cancer
Rice University chemists have discovered a way to load dozens of molecules of the anti-cancer drug paclitaxel onto tiny gold spheres. The result is a tiny ball, many times smaller than a living cell that literally bristles with the drug. view more (2007-09-13)
Ultrasensitive detector promises improved treatment of viral respiratory infections
A Vanderbilt chemist and a biomedical engineer have teamed up to develop a respiratory virus detector that is sensitive enough to detect an infection at an early stage, takes only a few minutes to return a result and is simple enough to be performed in a pediatrician's office. view more (2009-06-29)
Inside a quantum dot: Tracking electrons at trillionths of a second
Researchers at the EPFL (Ecole Polytechnique Federale de Lausanne) have developed a new machine that can reveal how electrons behave inside a single nano-object. view more (2005-11-28)
COPD rates, higher than expected in China, will continue to grow
In China, chronic obstructive pulmonary disease (COPD) in people over the age of 40 is much more prevalent than previously thought, according to researchers in Guangdong. view more (2007-10-12)
Researchers effectively treat tumors with use of nanotubes
By injecting man-made, microscopic tubes into tumors and heating them with a quick, 30-second zap of a laser, scientists have discovered a way to effectively kill kidney tumors in nearly 80 percent of mice. view more (2009-08-04)
Karolinska researcher named fellow of AAAS
Professor Lars Hammarström of the Karolinska Institutet, Sweden, has been awarded the honorary title of Fellow of the American Association for the Advancement of Science, AAAS. As a member of the Section for Odontology, Professor Lars Hammarström has been elected a Fellow of the AAAS for his valuable contributions to education and... view more... (2002-12-12)
Gold bowties may shed light on molecules and other nano-sized objects
One of the great challenges in the field of nanotechnology is optical imaging-specifically, how to design a microscope that produces high-resolution images of the nano-sized objects that researchers are trying to study. view more (2005-08-31)
Freezing kidney cancer: Hot treatment should be new gold standard for destroying small tumors
Freezing kidney tumors-using a safe minimally invasive interventional radiology treatment that kills the cancer 100 percent effectively without surgery-should be the gold standard or first treatment option for all individuals with tumors that are 4 centimeters in size or smaller. And, this treatment-interventional cryoablation-is a viable option... view more... (2009-03-09)
4,000 Year Old Archer With Golden Earrings
The richest Early Bronze Age burial in Britain has been found by astonished archaeologists. The grave of a mature man was found near Amesbury, Wiltshire and contains far more objects than any other burial of this date, about 2,300 BC. He has been identified as an archer on the basis of stone arrow heads and stone wristguards that protected the arm... view more... (2002-05-15)
Early Bronze Age mortuary complex discovered in Syria
An ancient, untouched Syrian tomb that wowed the archaeological world on its discovery by Johns Hopkins University researchers nearly six years ago has revealed another secret: It is not alone. view more (2006-10-25)
