Imagine if conditions that presently cause blindness could be treated by simply by fabricating new tissue, and using it to replace the defective part of the retina. We may not be at that point yet, but we've definitely taken a step closer, thanks to research being conducted at the University of Cambridge. Scientists there have successfully used an inkjet printer to "print" rats' retinal cells onto a substrate, paving the way for the creation of custom-made eye-repair material.  Read More

Anyone who has left youth behind them knows that bumps and scrapes don't heal as fast as they used to. But that could change with researchers at the Stem Cell Program at Boston Children's Hospital finding a way to regrow hair, cartilage, bone, skin and other soft tissues in a mouse by reactivating a dormant gene called Lin28a. The discovery could lead to new treatments that provide adults with the regenerative powers they possessed when very young.  Read More

The Nobel Prize medal is awarded to honor the highest contributions to the sciences (Photo...

The Nobel Prize in Physiology or Medicine for 2013 was awarded jointly today to James E. Rothman, Randy W. Schekman and Thomas C. Südhof "for their discoveries of machinery regulating vesicle traffic, a major transport system in our cells."  Read More

We report on the latest developments in biological research all the time here at Gizmag, but it's easy to forget just how beautiful biology can appear when observed at the cellular level. On this note, GE Healthcare’s Life Sciences Cell Imaging Competition has announced its winners for 2012, giving us the opportunity to appreciate the images which will soon light up New York’s Times Square.  Read More

Researchers have found that oxygen-containing free radicals aid rather than harm cell rege...

Researchers at the University of Manchester have found that Reactive Oxygen Species (ROS) – oxygen-containing free radicals that are commonly believed to be harmful to cells – actually play a vital role in the regeneration of the tails of tadpoles. The finding could have profound implications for the healing and regeneration of human tissue.  Read More

The latest development in the quest for eternal youth concerns that most visible sign of aging – the skin. Scientists at the University of Michigan (U-M) have found that it might be possible to slow the decline of aging tissue by focusing not on the cells but on the stuff that surrounds those cells. By adding more filler to the fiber-filled area around the cells, they were able to make the skin cells of senior citizens act like younger cells again.  Read More

Researchers at Pennsylvania State University have developed a new prototype cell-sorting device which uses sound waves to arrange cells far more efficiently than before. The advance in efficiency presents the possibility that future medical analytical devices could be scaled-down to a size much smaller than is currently the case.  Read More

The M13 bacteriophage can be used to deliver a DNA message in the “Bi-Fi” biological inter...

The internet has revolutionized global communications and now researchers at Standford University are looking to provide a similar boost to bioengineering with a new process dubbed “Bi-Fi.” The technology uses an innocuous virus called M13 to increase the complexity and amount of information that can be sent from cell to cell. The researchers say the Bi-Fi could help bioengineers create complex, multicellular communities that work together to carry out important biological functions.  Read More

A diagram of the tissue-producing device

Tissue engineering is definitely an exciting field – the ability to create living biological tissue in a lab could allow scientists to do things such as testing new drugs without the need for human subjects, or even to create patient-specific replacement organs or other body parts. While some previous efforts have yielded finished products that were very small, a microfluidic device being developed at the University of Toronto can reportedly produce sections of precisely-engineered tissue that measure within the centimeters.  Read More

Scientists have had success in tracking the passage of blood cells within the body, by lab...

Thanks to advances in stem cell therapy, it is now possible to use engineered white blood cells to fight diseases such as HIV within the human body. When such treatments are being developed, however, it can be difficult to track where the introduced cells travel within a patient’s system, and how many of them make it to their target. Now, thanks to research being carried out at the University of Edinburgh's Centre for Cardiovascular Science, those cells can be magnetically labeled.  Read More
