Artificial Bones

Engineers at Georgia Tech have used skin cells to create artificial bones that mimic the ability of natural bone to blend into other tissues, such as tendons or ligaments. The artificial bones display a gradual change from bone to softer tissue rather than the sudden shift of previously developed artificial tissue, allowing them...

Hubble Solves Mystery

NASA's Hubble Space Telescope has found an answer to a long-standing puzzle by resolving giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275. One of the closest giant elliptical galaxies, NGC 1275 hosts a supermassive black hole. Energetic activity of gas swirling near the black...

Less Corny Ethanol

A yeast geneticist on the campus of Indiana University-Purdue University Indianapolis (IUPUI) is close to developing mutant yeast for ethanol production that would reduce or eliminate the need to use corn to make the alternative fuel. When corn is used to make ethanol, corn kernels are ground to produce starch and the starch...

X-Ray Eyes

The advantage of using two eyes to see the world around us has long been associated with our capacity to see in 3-D. Now, Rensselaer Polytechnic Institute scientist Mark Changizi has uncovered an eye-opening advantage to binocular vision: our ability to see through things. An assistant professor of cognitive science at Rensselaer,...

Gold Power

Gold's ability to catalyze the conversion of toxic carbon monoxide (CO) into more benign carbon dioxide (CO2) at room temperature lay hidden until the 1980s. Since the discovery, scientists have sought to determine exactly how gold nanoparticles function as catalysts. Now researchers from Lehigh University, Cardiff University, and the...

Breast Cancer Detection

Scientists from Finland, Germany, and the European Synchrotron Radiation Facility (ESRF) have developed a new X-ray technique for the early detection of breast cancer. Current X-ray mammography fails to identify about 10 to 20% of palpable breast cancers because glandular tissues can mask cancer lesions. Better results...
