Study finds patients overestimate cancer screening history
A new American Cancer Society study finds female African American patients tend to overestimate their level of cancer screening, indicating that current estimates of screening based on self-reported data may be lower than reported.   view more (2008-04-18)

Marijuana use on the rise among Ontario adults, CAMH reports
While this CAMH Monitor eReport reveals some promising substance use trends among Ontario adults, its revelation of a substantial increase in cannabis use raises a significant public health flag.   view more (2008-04-15)

Getting wired for terahertz computing
University of Utah engineers took an early step toward building superfast computers that run on far-infrared light instead of electricity: They made the equivalent of wires that carried and bent this form of light, also known as terahertz radiation, which is the last unexploited portion of the... view more (2008-04-15)

Cycling more intelligently
Cycling is fun - if you can find the right tread. But those who tire themselves out quickly lose the desire to conquer the world on two wheels.   view more (2008-04-14)

Cognitive tests are the best way to select medical students
Cognitive ability tests are the best way for medical schools to select their entrants, rather than interviews and psychological tests, says an editorial in this week's BMJ.   view more (2008-04-11)

Researchers pilot new electronic system for infectious illness
Researchers at Harvard Pilgrim Health Care, Harvard Medical School, Atrius Health, and the Massachusetts Department of Public Health have created and tested a set of computer programs that use electronic medical records to help clinicians detect contagious illness and automatically report them to... view more (2008-04-10)

Geisinger study: Use of digital health records improve health of the elderly
Use of medications that are linked to increased risk of falls in the elderly can be reduced through careful review of patient files in the Electronic Health Record, new Geisinger research shows.   view more (2008-04-08)

The Not-So-Digital Future of Digital Signal Processing
Fungi processing audio signals. E. Coli storing images. DNA acting as logic circuits. It's possible, and in some cases, it's already happened. In any event, performing digital signal processing using organic and chemical materials without electrical currents could be the wave of the future.   view more (2008-04-08)

National Institute of Standards and Technology (NIST)
Electronic commands passed from machine to machine over data networks increasingly drive today's precisely timed and sequenced manufacturing production lines.   view more (2008-04-03)

Music File Compressed 1,000 Times Smaller than MP3
Researchers at the University of Rochester have digitally reproduced music in a file nearly 1,000 times smaller than a regular MP3 file.   view more (2008-04-02)

Study finds improvement in the care of children with cancer at the end of life
Expanded use of palliative care services is associated with enhanced communications between families and caregivers, improved symptoms management, and better quality of life for children dying from cancer, according to study by researchers at Dana-Farber Cancer Institute and Children's Hospital... view more (2008-03-31)

Neurons hard wired to tell left from right
It's well known that the left and right sides of the brain differ in many animal species and this is thought to influence cognitive performance and social behaviour. For instance, in humans, the left half of the brain is concerned with language processing whereas the right side is better at... view more (2008-03-31)

Foldable and stretchable, silicon circuits conform to many shapes
Scientists have developed a new form of stretchable silicon integrated circuit that can wrap around complex shapes such as spheres, body parts and aircraft wings, and can operate during stretching, compressing, folding and other types of extreme mechanical deformations, without a reduction in... view more (2008-03-28)

SUNY researcher issued patent for virtual telemicroscope
After nearly ten years of research and development, scientists at SUNY Downstate Medical Center in Brooklyn and Peking University in Beijing were awarded a United States patent for their virtual telemicroscope. This patented software permits off-site pathologists to diagnose cancer or other... view more (2008-03-28)

Good luck indeed: 53 million-year-old rabbit's foot bones found
One day last spring, fossil hunter and anatomy professor Kenneth Rose, Ph.D. was displaying the bones of a jackrabbit's foot as part of a seminar at the Johns Hopkins University School of Medicine when something about the shape of the bones looked oddly familiar.   view more (2008-03-20)

UC San Diego Scientists Develop Sensor for Homemade Bombs
A team of chemists and physicists at the University of California, San Diego has developed a tiny, inexpensive sensor chip capable of detecting trace amounts of hydrogen peroxide, a chemical used in the most common form of homemade explosives.   view more (2008-03-19)

NIST team proves bridge from conventional to molecular electronics possible
Researchers at the National Institute of Standards and Technology (NIST) have set the stage for building the "evolutionary link" between the microelectronics of today built from semiconductor compounds and future generations of devices made largely from complex organic molecules.   view more (2008-03-19)

Researchers study new drug and indications for heated chemotherapy treatment
Studies have shown that surgery combined with Intraperitoneal Hyperthermic Chemotherapy (IPHC) can improve survival rates for select patients with peritoneal carcinoma (cancer of the lining of the abdominal cavity) that has spread from colorectal or appendix cancer.   view more (2008-03-17)

Single-Crystal Semiconductor Wire Built into an Optical Fiber
An international science team from Penn State University in the United States and the University of Southampton in the United Kingdom has developed a process for growing a single-crystal semiconductor inside the tunnel of a hollow optical fiber. The device adds new electronic capabilities to... view more (2008-03-13)

Implantable medical devices may expose patients to security, privacy risks; solutions suggested
Some medical devices such as implantable cardiac defibrillators and pacemakers are now equipped with wireless technology, allowing for remote device checks and freeing patients from repeated doctor visits. But this convenience may come with unanticipated risks.   view more (2008-03-13)

A new finding in liver transplantation and antifibrinolytics?
Orthotopic liver transplantation (OLT) is associated with severe bleeding and considerable transfusion requirements. There are several reasons for this severe bleeding in OLT. Hemostatic abnormalities remain a major cause.   view more (2008-03-13)

New NIST detector can 'see' single neutrons over broad range
Researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland have developed a new optical method that can detect individual neutrons and record them over a range of intensities at least a hundred times greater than existing detectors.   view more (2008-03-11)
