Scientists have made a new theoretical advance in atomic behavior that could lead to sharper magnetic resonance imaging pictures. The discovery could one day help enable the development of portable MRI machines.
A 10-year-old Chicago girl born with an abnormally small bladder that made her incontinent has become the first patient to benefit from a new robotic-assisted bladder-reconstruction procedure. The surgeons have now performed the operation six times, with good results and no significant complications.

The world’s car park is growing. It has become so big that the impact of emissions from today’s road traffic on the global temperature in 2100 will be six times greater than that from today’s air traffic.

Females with cystic fibrosis have more severe disease than males with cystic fibrosis and have a shorter lifespan. Although many suggestions have been put forward to explain this sex-related difference, a concrete mechanism to explain it has remained elusive.
Airtight containers are not always so airtight. As any child will discover the day after a birthday party, even a tightly tied helium balloon will leak its gas out over the course of many hours. Now scientists have come up with a supremely efficient barrier that lets nothing in or out.
Children whose eyes are misaligned and point outward are at significantly increased risk of developing mental illness by early adulthood, according to findings published in Pediatrics.

Research into the development of invisibility devices has spurred two physicists’ thought on the behavior of light to overcome the seemingly intractable problem of optical singularities which could soon lead to the manufacturing of a perfect cat’s eye.

A new species of bacterium that causes leprosy has been identified through intensive genetic analysis of a pair of lethal infections, a research team reports.
The Galapagos Islands, which provided impetus and inspiration for Charles Darwin’s seminal work, “On the Origin of Species,” are home to unique populations of reptiles. Since the time of man’s first visit in the 16th century to this crucial incubator for evolutionary theory, the islands’ native plants and animals have faced grave challenges, including severe [...]

One of the most critical stages in establishing a pregnancy is the implantation of the embryo in the wall of the uterus. Although the accumulation of immune cells known as DCs has been observed in the uterus after fertilization and prior to implantation, their function was not known.
