Knee ’scaffold’ study offers new hope for injury victims

Scientists from the University of Leicester are taking revolutionary research further with the potential to offer new hope for knee-injury victims.

They are following up international research that aims to improve knee cartilage repair techniques, termed ‘chrondrocyte implantation’. The procedure, developed in Sweden ten years ago, involves growing a patient’s knee cartilage cells in a laboratory, which are then implanted through open knee surgery. Recent exciting developments revolve

Genetic "Signature" Linked to Severe Lupus Symptoms

A team of scientists supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) and other parts of the National Institutes of Health (NIH) and the private sector, have discovered a genetic “signature” present in some patients with systemic lupus erythematosus (SLE) who develop such life-threatening complications as blood disorders, central nervous system damage and kidney failure.

A decade later, gene discovered by Temple researchers found to be multi-functional

A gene discovered by Temple University researchers a decade ago has proved to be multi-functional, with the discovery of its important roles in cell differentiation, HIV transcription, and tumorigenesis.

Cdk9 (cyclin-dependent kinases) and cdk10 were originally isolated by Antonio Giordano, M.D., Ph.D., then a researcher in Temple’s Fels Cancer Institute, and his team in 1992. They are members of a family of kinases originally referred to as a PITALRE, which is the name of the amino aci

Falling prey to machines

Can sentient machines evolve?

It’s coming, but when? From Garry Kasparov to Michael Crichton, both fact and fiction are converging on a showdown between man and machine. But what does a leading artificial intelligence expert–the world’s first computer science PhD–think about the future of machine intelligence? Will computers ever gain consciousness and take over the world?

“Computer sentience is possible,” said John Holland, professor of electrical engineering an

NCAR observing system finds high-level moisture with global implications

Hard-to-detect clouds and water vapor, hidden until now from most atmospheric sensors, could be helping to shape global climate. An instrument package developed by the National Center for Atmospheric Research (NCAR) has detected layers of moisture, indicative of high-level cirrus clouds, that were missed by standard weather balloons and other instruments. The findings are being presented by NCAR scientist Junhong Wang on Tuesday, February 11, in Long Beach, California, at the annual meeting of the Am
