DNA strands can act as a glue to hold together 3-D-printed materials that could someday be used to grow tissues and organs in the lab, a new study has found. Researchers from the University of Texas at Austin said that although scientists have used nucleic acids such as DNA to assemble objects, most of these are nanosized - so tiny that humans can’t see them with the naked eye.
Men are less likely to quit smoking when looking at attractive women, according to a new study which asked men to rate how appealing pictures of different women were. In an experiment, scientists from Taiwan asked 76 men to rate pictures of various women.
Parents, take note! Daytime naps of 30 minutes or more help babies retain and remember new behaviours, a first of its kind study has found. Researchers from the University of Sheffield, UK, and Ruhr University Bochum, Germany explored whether daytime sleep after learning helped babies to remember new behaviour.
Researchers have for the first time grown human skeletal muscle in the lab which contracts and responds just like native tissue to external stimuli such as electrical pulses, biochemical signals and pharmaceuticals. The lab-grown tissue will allow researchers to test new drugs and study diseases in functioning human muscle outside of the human body to provide personalised medicine to patients.
The deadly Ebola epidemic in Liberia could likely be eliminated by June if the current high rate of hospitalisation and vigilance can be maintained, according to a new model developed by scientists.
Women crave cigarettes more strongly during their periods, according to a new study which suggests taking the menstrual cycle into consideration can help women smokers quit. The study was conducted by Adrianna Mendrek of the University of Montreal and its affiliated Institut universitaire en sante mentale de Montreal.
Researchers have designed a new app that can help kids growing up with autism develop basic social skills. The app, called Look At Me, aims to train autistic children to maintain eye contact and convey basic emotions.
Researchers have patented a drug that could produce some of ecstasy's euphoric effects and at the same time limit the amount of alcohol people drink.
A new study has found that high levels of arsenic in drinking water were associated with an "astonishing" 50 per cent drop in breast cancer deaths in Chile. The study presents results of breast cancer mortality data from a region in Chile where residents were inadvertently exposed to high levels of arsenic, a naturally occurring element found in many minerals.
A research consortium headed by Professor Hossam Haick of the Technion-Israel Institute of Technology is developing a product that, when coupled with a smartphone, will be able to screen the user’s breath for early detection of life-threatening diseases.
