Viewing cancer on the move: New device yields close-up look at metastasis

Posted: 31 Oct 2014 09:04 AM PDT

Rngineers have invented a lab device to give cancer researchers an unprecedented microscopic look at metastasis, the complex way that tumor cells spread through the body, causing more than 90 percent of cancer-related deaths.

Computer game could help visually impaired children live independently

Posted: 31 Oct 2014 05:20 AM PDT

A new computer game is being test that researchers hope could hold the key to helping visually-impaired children lead independent lives. Developed by a team of neuroscientists and video game designers, the Eyelander game features exploding volcanoes, a travelling avatar and animated landscapes. The idea is to improve the functional vision of children who have sight issues due to a brain injury rather than damage to the eye itself.

Horse racing position cuts drag up to 66 per cent

Researchers have revealed precisely how much different slipstreaming tactics reduce drag on a horse during a race.  

Digital Therapist: Computer program analyzes speech, mental health

Posted: 31 Oct 2014 05:19 AM PDT

A program that analyzes your speech and uses it to gain information about your mental health could soon be feasible, thanks in part to new research showing that certain vocal features change as patients' feelings of depression worsen.

Doubt cast over air pollution link between childhood leukemia, power lines

Posted: 30 Oct 2014 06:37 PM PDT

Researchers from the UK have called into question a theory suggesting that a previously reported risk of leukemia among children born close to overhead power lines could be caused by an alteration to surrounding air pollution.

High-intensity sound waves may aid regenerative medicine

Posted: 30 Oct 2014 11:19 AM PDT

Researchers have developed a way to use sound to create cellular scaffolding for tissue engineering, a unique approach that could help overcome one of regenerative medicine's significant obstacles.

Making lab-grown tissues stronger

Posted: 30 Oct 2014 10:35 AM PDT

Lab-grown tissues could one day provide new treatments for injuries and damage to the joints, including articular cartilage, tendons and ligaments. Cartilage, for example, is a hard material that caps the ends of bones and allows joints to work smoothly. Biomedical engineers are exploring ways to toughen up engineered cartilage and keep natural tissues strong outside the body.

One hormone, Two roles: Sugars differentiate seasonality, metabolism

Posted: 30 Oct 2014 10:33 AM PDT

The mechanism on how a single hormone manages to trigger two different functions, i.e. seasonal sensing and metabolism, without any cross activity has been identified by researchers.

The geometry of RNA and its 3D structure

Posted: 30 Oct 2014 07:12 AM PDT

To understand the function of an RNA molecule, similar to the better-known DNA and vital for cell metabolism, we need to know its three-dimensional structure. Unfortunately, establishing the shape of an RNA strand is anything but easy and often requires a combination of experimental techniques and computer-based simulations. Many computing methods are used but these are often complex and slow, and vary depending on the problem at hand. A team of scientists has devised a simple and versatile method, based on the geometry of the RNA molecule.

New molecular imaging technology could improve bladder-cancer detection

Posted: 29 Oct 2014 11:54 AM PDT

A new strategy has been developed that researchers say could detect bladder cancer with more accuracy and sensitivity than standard endoscopy methods. Endoscopy refers to a procedure in which surgeons use an instrument equipped with a lens to see inside the patient.
