Monitoring Broken Bones Without Using Electronics: Wireless Bone Monitor

The novel sensor is intended one day to help doctors monitor broken bones as they grow back together. Depending on the values of the forces measured by the sensor, they can decide whether the healing process is progressing normally or whether there is a danger that the fracture or implants might be overloaded. Until now doctors have used expensive and complicated electronic devices which sent the...

New Molecules With Many Branches Will Help Unleash Potential Of Nanotechnology

Materials science and the pharmaceutical industry could soon be revolutionized by emerging nanotechnologies based on designer molecules with long complex tree-and branch structures. Such molecules offer almost limitless scope for design of bespoke compounds for specific applications in disease therapy, for novel materials such as resins, as well as electronic displays, and energy storage. Almost...

New test promises quicker, more accurate evaluation for cystic fibrosis patients

Researchers at National Jewish Health have identified a simple gene-based blood test that more accurately and quickly measures cystic fibrosis patients' response to therapy than current tests. The test, a measure of inflammatory gene expression, could improve patient care and help clear a backlog of promising medications now hung up in clinical trials.

Operate a piano pedal with the mouth

The Heidelberg researcher Dr.-Ing. Rüdiger Rupp has developed a method with which a pianist can operate the right pedal of a concert grand wirelessly -- a first in the world. A paraplegic pianist can thus overcome the handicap of being able to play the piano using only his arms and hands.

Phony Friends? Rejected People Better Able To Spot Fake Smiles

All of us have "faked a smile" at some point. Now, a new study might make us think twice about sending out a phony grin. It has been shown that individuals who are experiencing rejection are better at picking up subtle social cues and according to a recent study published in Psychological Science, socially rejected people are particularly good at discerning fake smiles from real...

Phony friends? Rejected people better able to spot fake smiles

All of us have "faked a smile" at some point. Now, a new study might make us think twice about sending out a phony grin. It has been shown that individuals who are experiencing rejection are better at picking up subtle social cues and according to a recent study published in Psychological Science, socially rejected people are particularly good at discerning fake smiles from real ones.

Sensitive Ultrasound To Spot Early-stage Cancer

Researchers have developed highly sensitive ultrasound equipment that can detect tiny quantities of reflective microbubbles engineered to stick to specific tumor cells. The technique should pick up tumors early and improve patients' chances of survival.

Study will examine how children with Down syndrome learn

Researchers at the University of Denver Morgridge College of Education are conducting a groundbreaking study that will compare two early literacy intervention approaches to educating young children with Down syndrome. The Rocky Mountain Down Syndrome Educational Fund is funding the study, which hopes to improve teaching methods for children with the condition.

Toxic bile damages the liver

Researchers at the Heidelberg University Hospital have discovered a new genetic disease that can lead to severe liver damage. Because a protective component of the bile is missing, the liver cells are exposed to the toxic components of the bile, resulting in cirrhosis of liver. This could explain some of the cases of liver cirrhosis of unknown origin and open up a new approach for treatment. The...

University of Western Ontario cameras capture 'fireball'

For the second time this year, the University of Western Ontario Meteor Group has captured incredibly rare video footage of a meteor falling to Earth. Astronomers suspect the fireball dropped meteorites in a region north of Guelph, Ontario, Canada, that may total as much as a few hundred grams in mass. The Physics and Astronomy Department at Western has a network of all-sky cameras in southern...

Youth from poor neighborhoods 4 times more likely to attempt suicide

Youth in their late teens who live in poor neighborhoods are four times more likely to attempt suicide than peers who live in more affluent neighborhoods, according to a new study from Canada's Universite de Montreal and Sainte-Justine Hospital Research Center, as well as Tufts University in the US. The researchers also found youth from poor neighborhoods are twice as likely to report suicidal...
