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...
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,...
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...
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...
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,...
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...
Laboratory-grown vaginas implanted in patients
Scientists reported today the first human recipients of laboratory-grown vaginal organs. A research team led by Anthony Atala, M.D., director of Wake Forest Baptist Medical...
DNA nanobots deliver drugs in living cockroaches
It's a computer – inside a cockroach. Nano-sized entities made of DNA that are able to perform the same kind of logic operations as a...
Recycling astronaut urine for energy and drinking water
On the less glamorous side of space exploration, there’s the more practical problem of waste — in particular, what to do with astronaut pee. But...

DNA modifications measured in blood signal related changes in the brain
Johns Hopkins researchers say they have confirmed suspicions that DNA modifications found in the blood of mice exposed to high levels of stress hormone—and showing...
Living organ regenerated for first time
A team of scientists at the University of Edinburgh has succeeded in regenerating a living organ for the first time. The team rebuilt the thymus...
Researchers explain how our immune system kills abnormal blood cells
A team of researchers at the IRCM, led by André Veillette, MD, explains how our immune system kills abnormal blood cells. Their discovery, recently published...
Synthetic gene circuits pump up cell signals
Synthetic genetic circuitry created by researchers at Rice University is helping them see, for the first time, how to regulate cell mechanisms that degrade the...
