Growing cartilage: bioactive nanomaterial promotes growth of new cartilage
|
|
Researchers have designed a bioactive nanomaterial that promotes the growth of new cartilage in vivo and without the use of expensive growth factors. The therapy is minimally invasive, utilizes bone marrow stem cells and produces natural cartilage. Unlike bone, cartilage does not grow back, and it cannot effectively be replaced. Countless people learn this all too well when they bring their bad knees, shoulders and elbows to an orthopedic surgeon.

Second 'quantum logic clock' based on aluminum ion is now world's most precise clock
|
|
Physicists have built an enhanced version of an experimental atomic clock based on a single aluminum atom that is now the world's most precise clock, more than twice as precise as the previous pacesetter based on a mercury atom. The new aluminum clock would neither gain nor lose one second in about 3.7 billion years.

An Early Warning System for Cancer
|
|
Autoantibodies could alert doctors to cancer development.
A new screening tool developed by scientists in Denmark may help detect the earliest stages of cancer by taking advantage of the body's own defenses. The researchers constructed a microarray system that analyzes patients' blood for a specific class of immune agents called autoantibodies. These are agents that attack the body's own tissue, targeting what they perceive as "foreign" cells, such as specific molecules on the surface of tumors.

Method of the future uses single-cell imaging to identify gene interactions
|
|
(Cold Spring Harbor Laboratory) Cellular imaging offers a wealth of data about how cells respond to stimuli, but harnessing this technique to study biological systems is a daunting challenge. In a study published online in Genome Research, researchers have developed a novel method of interpreting data from single-cell images to identify genetic interactions within biological networks, offering a glimpse into the future of high-throughput cell imaging analysis.

Princeton scientist makes a leap in quantum computing
|
|
(Princeton University) Princeton University's Jason Petta has demonstrated a method that alters the properties of a lone electron without disturbing the trillions of electrons in its immediate surroundings. The feat is essential to the development of future varieties of superfast computers with near-limitless capacities for data.

UVa scientists: Use wastewater to solve biofuel limitations
|
|
As an environmentally sustainable alternative to current algae production methods, the researchers propose situating algae production ponds behind wastewater treatment facilities to capture phosphorous and nitrogen — essential nutrients for growing algae that would otherwise need to be produced from petroleum.

Civil engineer documents poor Haiti infrastructure
|
|
A Bay Area civil engineer who specializes in earthquake construction has just returned from inspecting many of the damaged buildings in Haiti. And what he saw in Haiti, he has never seen before -- not on this scale.
