New Paint-on, See-through bandage Emits Phosphorescent Glow for Healing Below

Credit: Li/Wellman Center for Photomedicine.

An interdisciplinary  team of researchers has created a paint-on, see-through, “smart” bandage that glows to indicate a wound’s tissue oxygenation concentration. Oxygenation plays a crucial role in healing, so mapping it in severe wounds and burns can help to significantly improve the success of surgeries to restore limbs and physical functions. “Information about tissue oxygenation is clinically relevant but is often…

A field researcher from America has transplanted fecal microbiome from a Tanzanian tribesman to his own gut. Why? Well… to see what happens, basically. “AS THE SUN set over Lake Eyasi in Tanzania, nearly thirty minutes had passed since I had inserted a turkey baster into my bum and injected the feces of a Hadza man – a member of one of…

Heart rate variability keeps the body in optimal shape

heartrate

The heart regularly speeds up or down its beating frequency to adjust to the body’s needs. Even in stable conditions (when you’re not particularly active or your active for a constant time), the amount of time between heart beats is variable. A team of doctors and engineers at Caltech’s Division of Engineering and Applied Science have now found a better way to assess…

Gut bacteria may control your mind by influencing your dietary choices

gut_bacteria_food_craving

Our gut hosts an enormous population of bacteria, each species with its own niche (they feed on certain foods), which outnumbers our own cells 100-fold. Most of these bacteria are good bacteria, though. In fact, you couldn’t survive without most of them! They’re among the best decomposers, breaking down dead and organic matter otherwise impossible by the gut alone. But…

Japanese woman is first recipient of next-generation stem cells

Researchers were able to grow sheets of retinal tissue from induced pluripotent stem cells, and have now implanted them for the first time in a patient.

A Japanese woman in her 70s is the world’s first recipient of cells derived from induced pluripotent stem cells, a technology that promises to work wonders and has the scientific community excited about the perspectives. Surgeons working on the case created the retinal tissue after reverting the patient’s own cells to ‘pluripotent’ state. If you’d like to benefit from stem cells, but…

These rocks in your head keep you balanced

calcium_carbonate_ear

The beautiful colored image above might look like beach pebbles, yet in reality it shows a glimpse from an even tinnier world – it’s a colored scanning electron micrograph (SEM) of calcium carbonate deposited on the surface of an otolith, found in the Acoustic Macula. These tiny debris also fit a purpose, helping the body stay in equilibrium, whether in static (position of the head) or dynamic equilibrium (relative position function of linear acceleration)…

Boy born without ears has a pair made from his ribs

Kieran-Sorkin-from-Watfor-011

Nine-year-old Kieran Sorkin was born without ears, but now, doctors made him a pair of ears from his own ribs. Kieran suffered from a rare condition in which his ears didn’t fully form – he had just small lobes where his ears should have been. He was almost deaf, but thanks to several previous procedures, his hearing slowly started to…

Better, simple way to regrow damaged corneas shines hope for blind patients

restored_cornea

A novel and highly effective technique was found to enhance regrowth of human corneal tissue to restore vision, using a newly identified molecule that acts as a marker for limbal cells – stem cells that are paramount to retinal regeneration. The findings could greatly improve the vision of patients suffering from severe burns, victims of chemical injury, and others with…

You could be sitting alone and still be completely outnumbered for your body is home to trillions upon trillions of tiny passengers – bacteria. In fact, there as ten times more bacteria living inside you then cells in the body. Don’t get scared, though. The vast majority of these co-redident organisms are our friends. They help us digest food, provide…
