Regenerated Esophagus Transplanted in Rats

Tissue engineering has been used to construct natural oesophagi, which in combination with bone marrow stem cells have been safely and effectively transplanted in rats. The study, published in ...

Hair from infants gives clues about their life in the womb

Like rings of a tree, hair can reveal a lot of information about the past. It can tell if a person recently used drugs or an athlete was doping. It can...

Human Microbiome Project: a map of every bacterium in the body

As scientists catalog the trillions of bacteria found in every nook and cranny of the human body, a new look by the University of Michigan shows wide variation in the types...

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. Photo Credits: GOOGLE Personal portable information...

Synapses Learning

Synapses are the points of contact at which information is transmitted between neurons. Without them, we would not be able to form thoughts or remember things. For memories to endure, synapses...

Why your nose can be a pathfinder

Researchers at the Kavli Institute for Systems Neuroscience have recently discovered the process behind this phenomenon. The brain, it turns out, connects smells to memories through an associative process where neural...

HIV+ women respond well to HPV vaccine

A three-nation clinical trial found that a vaccine can safely help the vast majority of HIV-positive women produce antibodies against the cancer-causing human papillomavirus, even if their immune system is weak...

Reverse engineering to develop lung

How do embryos form the cells in our lungs, muscles, nerves and other tissues? A new process decodes the genetic instructions that enable the all-purpose cells of the embryo to multiply...

Brain activity may mark beginning of memories

By tracking brain activity when an animal stops to look around its environment, neuroscientists at the Johns Hopkins University believe they can mark the birth of a memory. The Zanvyl Krieger Mind/Brain...

Virus-fighting genes linked to mutations in cancer

Researchers have found a major piece of genetic evidence that confirms the role of a group of virus-fighting genes in cancer development. Dr Serena Nik-Zainal, first author from the Wellcome Trust...

Mechanical Forces Affect T-Cell Recognition and Signaling

T-cells are the body’s sentinels, patrolling every corner of the body in search of foreign threats such as bacteria and viruses. Receptor molecules on the T-cells identify invaders by recognizing their...

Brain cell discovery could open doors to targeted cancer therapies

Fresh insights into the processes that control brain cell production could pave the way for treatments for brain cancer and other brain-related disorders. University of Edinburgh Scientists have gained new understanding of the...

3D printing cancer cells to mimic tumours

A group of researchers in China and the US have successfully created a 3D model of a cancerous tumour using a 3D printer. The model, which consists of a scaffold of fibrous...

Scientists Grow Cartilage to Reconstruct Nose

Scientists at the University of Basel report first ever successful nose reconstruction surgery using cartilage grown in the laboratory. Cartilage cells were extracted from the patient’s nasal septum, multiplied and expanded...
