Slippery technology prevents harmful bacterial slime from forming on surfaces

Biofilms may no longer have any solid ground upon which to stand. A team of Harvard scientists has developed a slick way to prevent the troublesome bacterial communities from ever forming on a surface. Biofilms stick to just about everything, from copper pipes to steel ship hulls to glass catheters. The slimy coatings are more than just a nuisance, resulting in decreased energy efficiency, contamination of water and food supplies, and-especially in medical settings-persistent infections. Even cavities in teeth are the unwelcome result of bacterial colonies.

Researchers turn inanimate silicone and living cardiac muscle cells into a jellyfish

Using recent advances in marine biomechanics, materials science, and tissue engineering, a team of researchers at Harvard University and the California Institute of Technology (Caltech) have turned inanimate silicone and living cardiac muscle cells into a freely swimming "jellyfish."

2-D models may often give researchers misleading results

Imagine millions of cancer cells organized in thousands of small divots. Hit these cells with drugs and when some cells die, you have a candidate for a cancer drug. But a review published this week in the journal Expert Opinion on Drug Discovery argues that these 2D models in fact offer very little information about a potential drug's effects in the body and may often give researchers misleading results.

New microscopy technique can improve understanding of human tissues, biomaterials

Research from North Carolina State University demonstrates that a relatively new microscopy technique can be used to improve our understanding of human tissues and other biomedical materials. The study focused specifically on eye tissues, which are damaged by scarring in diabetic patients.

Scientists develop new low-dose CT-scan technique

Scientists have developed an X-ray imaging method that could drastically improve the contrast of computed tomography (CT) scans whilst reducing the radiation dose deposited during the scan. The new method is based on the combination of the high contrast obtained by an X-ray technique known as grating interferometry with the three-dimensional capabilities of CT.

Energy-efficient LED devices use UV light to kill pathogens

Research from North Carolina State University will allow the development of energy-efficient LED devices that use ultraviolet (UV) light to kill pathogens such as bacteria and viruses. The technology has a wide array of applications ranging from drinking-water treatment to sterilizing surgical tools.

New approach to advance quality of pregnancy monitoring

The University of California, San Diego Jacobs School of Engineering announced today that it is a Grand Challenges Explorations winner, an initiative funded by the Bill & Melinda Gates Foundation. Bioengineering Professor Todd Coleman, in collaboration with Materials Science and Engineering Professor John A. Rogers at the University of Illinois at Urbana-Champaign, will pursue an innovative global health and development research project, titled "Epidermal Electronics for Continuous Pregnancy Monitoring."

New system assesses and records mobility of bedridden patients

Healthy people move an average of two to four times per hour in their sleep. The movements are triggered by pain that occurs when tissue has an insufficient blood supply. The sleeping person changes position involuntarily, relieves the pressure point and therefore prevents bedsores, which are known in professional jargon as "decubitus ulcers".

Study explores resilin-like materials for vocal fold disorders

A one-inch long grasshopper can leap a distance of about 20 inches. Cicadas can produce sound at about the same frequency as radio waves. Fleas measuring only millimeters can jump an astonishing 100 times their height in microseconds. How do they do it? They make use of a naturally occurring protein called resilin.

Honeycomb biodegradable implant may help nerve regeneration: Study

Patients with severely injured limbs often suffer a devastating loss of sensation. The implants, called “nerve guidance conduits” or NGCs were produced by British and German engineers with a laser technique normally used to write complex electrical circuits. Made from a form of biodegradable plastic, they guide regrowing nerve fibres through individual channels to aid recovery. Once the nerves are fully regrown and reconnected, the device dissolves away.

New device can correct bone deformities in children

Another day, another four turns of the screw. That's just a part of life for people, primarily children, undergoing the long and difficult process of distraction osteogenesis, a method to correct bone deformities that leave one limb shorter than the other.
