The UC Berkeley researchers are hopeful that the smart bandage will do more than prevent n...

Bedsores are more than a pain in the backside for bedridden folk, they can develop into dangerous infections and heighten the chances of a patient dying. While swollen ulcers on the skin are a pretty sure sign of their presence, by this point it is often too late for some of their effects to be reversed. But a team of researchers have developed what could function as an early warning system, a smart bandage containing flexible electronics that detects tissue damage before it becomes visible on the surface of the skin.  Read More

Leader cells, shown here in fluorescent green, rush to the site of a wound with the follow...

When you cut on your finger or scrape your knee, cells rush to the wound and repair or replace the damaged tissue. But how exactly this works – in particular how certain cells become "leaders" in the process – has long been a mystery. Now researchers at the University of Arizona (UA) have identified the mechanisms that cause and regulate this collective cell migration. Armed with this knowledge, biomedical engineers will be able to design new tissue regeneration treatments for diabetes and heart disease as well as for slowing or stopping the spread of cancer.  Read More

We've already heard about swallowable capsules that can transmit video from within the digestive tract. Pictures will only tell you so much, though. That's why researchers from Australia's RMIT and Monash universities have now developed a capsule that measures concentrations of intestinal gases, and sends that data to a smartphone or other device.  Read More

Alzheimer's disease is a chronic neurodegenerative disease that most often begins in people over 65 years of age. Usually it starts slowly and continues to worsen over time until the sufferer succumbs to an increasing loss of memory, bodily functions and, eventually, death. Research has shown that there is an association with Alzheimer's and the accumulation of plaques that affect the neuronal connections in the brain. Now researchers at the University of Queensland have discovered a new way to remove these toxic plaques using a non-invasive form of ultrasound therapy.  Read More

With uncontrolled bleeding the major cause of deaths on the battlefield, researchers at the University of Washington have developed an injectable polymer that could stem bleeding and provide extra time to get the injured to medical care. Called PolySTAT, the new polymer stems blood loss by strengthening blood clots.  Read More

The heart-on-a-chip consists of a series of living cells molded into a structure that is a...

The growing number of biological structures being grown on chips in various laboratories around the world is rapidly replicating the entire gamut of major human organs. Now one of the most important of all – a viable functioning heart – has been added to that list by researchers at the University of California at Berkeley (UC Berkeley) who have taken adult stem cells and grown a lattice of pulsing human heart tissue on a silicon device.  Read More

Researchers from the Medical University of Vienna have developed a technique that allows amputees to control a robotic prosthesis with their mind when there's no neural connection left to exploit between the brain and the part of the hand that remains. Called "bionic reconstruction," the procedure was applied to three patients who were able to successfully use the prosthesis to undertake routine activities, thereby improving their quality of life.  Read More

A new nanoparticle is capable of carrying cancer-fighting drugs to a tumor site in the lun...

Scientists have developed drug-carrying nanoparticles capable of targeting cancer tissue in the lungs. By engineering the devices to release their payloads only once they reach the site of the tumor, the researchers hope to reduce the size of dosages required and also limit the side effects of conventional treatments.  Read More

Brain plaques (seen in blue) and other debris are normally swept away by cells called micr...

Researchers have identified a promising new target in the battle against certain neurological diseases. A protein known as TREM2 has been proven effective in clearing away unwanted debris in the brain, the unchecked buildup of which can lead to both Alzheimer's disease and multiple sclerosis (MS).  Read More

Nanometer-sized “drones” that deliver drugs to heal and stabilize fat deposits in arteries...

Scientists have developed targeted, biodegradable nano "drones" to deliver anti-inflammatory drugs that heal and stabilize arterial plaque in mice. Their work could pave the way for more effective prevention of heart attack and stroke in humans caused by atherosclerosis, in which artery walls thicken and suffer reduced plasticity due to an accumulation of white blood cells.  Read More
