Pink prosthetic arm ‘printed’ for teen girl by university students

Pink prosthetic arm ‘printed’ for teen girl by university students

Thirteen-year-old Sydney Kendall had one request for the Washington University in St. Louis students building her a robotic prosthetic arm: Make it pink. Kendall Gretsch, Henry Lather and Kranti Peddada, seniors studying biomedical engineering in the School of Engineering & Applied Science, accomplished that and more. Continue reading

Luminescent nanocrystal tags enable rapid detection of multiple pathogens in a single test

Luminescent nanocrystal tags enable rapid detection of multiple pathogens in a single test

A research team using tunable luminescent nanocrystals as tags to advance medical and security imaging have successfully applied them to high-speed scanning technology and detected multiple viruses within minutes. The research, led by Macquarie University in Sydney, Australia and Purdue University, builds on the team’s earlier success in developing a way to control the length of time light from a luminescent nanocrystal lingers, which introduced the dimension of time in addition to color and brightness in optical detection technology Continue reading

Faster dental treatment with new photoactive molecule

Faster dental treatment with new photoactive molecule

In modern dentistry, amalgam fillings have become unpopular. Instead, white composite materials are more commonly used, which at first glance can hardly be distinguished from the tooth Continue reading

Seeking causes of hyperactivity

Seeking causes of hyperactivity

The 60 trillion cells that comprise our bodies communicate constantly. Information travels when chemical compounds released by some cells are received by receptors in the membrane of another cell. In a paper published in the Journal of Neuroscience, the OIST Cell Signal Unit, led by Professor Tadashi Yamamoto, reported that mice lacking an intracellular trafficking protein called LMTK3, are hyperactive.

ADHD: Scientists discover brain’s anti-distraction system

ADHD: Scientists discover brain’s anti-distraction system

Two Simon Fraser University psychologists have made a brain-related discovery that could revolutionize doctors’ perception and treatment of attention-deficit disorders. This discovery opens up the possibility that environmental and/or genetic factors may hinder or suppress a specific brain activity that the researchers have identified as helping us prevent distraction. The Journal of Neuroscience has just published a paper about the discovery by John McDonald, an associate professor of psychology and his doctoral student John Gaspar, who made the discovery during his master’s thesis research.

Novel stapled peptide nanoparticle combination prevents RSV infection, study finds

Novel stapled peptide nanoparticle combination prevents RSV infection, study finds

New therapies are needed to prevent and treat respiratory syncytial virus (RSV) — a potentially lethal respiratory infection that can severely affect infants, young children and the elderly. Despite a wide range of anti-RSV efforts, there are no vaccines or drugs on the market to effectively prevent or treat the infection. Now researchers at the Dana-Farber/Boston Children’s Cancer and Blood Disorders Center and Harvard Medical School in Boston, MA, and the James A. Continue reading

How smells stick to your memories: Your nose can be a pathfinder

Waves in your brain make smells stick to your memories and inner maps: When I was a child I used to sit in my grandfather’s workshop, playing with wood shavings. Continue reading

Potential use of Google Glass in surgical settings

An article recently published in the International Journal of Surgery shows the potential applications for Google Glass in the surgical setting, particularly in relation to training. Personal portable information technology is advancing at a breathtaking speed. Continue reading

Intelligent prosthetic liners could ease pain for lower limb amputees

Intelligent prosthetic liners could ease pain for lower limb amputees

A new device could help to relieve the pain and discomfort experienced by thousands of amputees as a result of poorly fitting replacement lower limbs. Researchers are developing a prototype of the world’s first prosthetic ‘intelligent’ liner with integrated pressure sensors, which could be available to NHS patients in as little as three years. The sensors for the device, invented by Dr Liudi Jiang and an interdisciplinary team at the University of Southampton, measure the pressure and pulling forces at the interface between a patient’s stump and socket of their prosthesis Continue reading
