Magic Carpet Could Help Prevent Falls in Elderly

Posted:

A 'magic carpet' developed by scientists could prevent elderly from falling. Plastic optical fibres, laid on the underlay of the carpet, can bend when anyone treads on it and map, in real-time, their walking patterns. Tiny electronics at the edges act as sensors and relay signals to a computer. These signals can then be analysed to show the image of the footprint and identify gradual changes in walking behaviour or a sudden incident such as a fall or trip. ...

South Asian Women at Greater Risk of Stillbirths

Posted:

A recent research carried out at three Melbourne public hospitals, has pointed out that women born in South Asian countries, carry a huge risk of stillbirth as compared to Australian-born women. The reason behind this inequality is not fully clear, despite considering the usual risk factors for stillbirth. One of the important reasons for this disparity could be due to the low birth weight of babies born to women from South Asia. The risk of stillbirth in South ...

Heavy Drinking Leads to Changes in Brain Circuitry, Increasing Risk of Anxiety Problems

Posted:

A new study has found that heavy drinking of alcohol not only increases the number of traumatic events, such as domestic violence or car accidents, but also rewires the brain activity to make it harder for the drinker to recover psychologically from such events. "There's a whole spectrum to how people react to a traumatic event," said study author Thomas Kash, PhD, assistant professor of pharmacology at the University of North Carolina School of Medicine. "It's ...

Sense of Smell in Mice Restored by NIH-Funded Researcher Via Genetic Technique

Posted:

The ability to smell in a mouse model of a human genetic disorder that causes congenital anosmia has been restored by scientists funded by the National Institutes of Health. Anosmia is the inability to smell from birth. The approach uses gene therapy to regrow cilia, cell structures that are essential for olfactory function. The study was funded by four parts of NIH: the National Institute on Deafness and Other Communications Disorders (NIDCD), the National Institute ...

New Simulation That Accurately Explains Effects of HIV Drugs Developed

Posted:

Researchers at Johns Hopkins and Harvard University have revealed that they have used data from thousands of tests of more than 20 commonly used HIV drugs to develop a new computer simulation that accurately explains the effects of HIV drugs. Already, the model clarifies how and why some treatment regimens fail in some patients who lack evidence of drug resistance. Researchers say their model is based on specific drugs, precise doses prescribed, and on "real-world ...

Banned PIP Breast Implants Contain Unidentifiable Chemicals
