Novel 3-D manufacturing leads to highly complex, bio-like materials
Washington State University researchers have developed a unique, 3-D manufacturing method that for the first time rapidly creates and precisely controls a material's architecture from the nanoscale to centimeters -- with results that closely mimic the intricate architecture of natural materials like wood and bone.

Brake dust may cause more problems than blackened wheel covers
Metals from brakes and other automotive systems are emitted into the air as fine particles, lingering over busy roadways. Now, researchers at Georgia Institute of Technology have shown how that cloud of tiny metal particles could wreak havoc on respiratory health.

Nanoengineers 3-D print biomimetic blood vessel networks
Nanoengineers at the University of California San Diego have 3-D printed a lifelike, functional blood vessel network that could pave the way toward artificial organs and regenerative therapies. The new research addresses one of the biggest challenges in tissue engineering: creating lifelike tissues and organs with functioning vasculature -- networks of blood vessels that can transport blood, nutrients, waste and other biological materials -- and do so safely when implanted inside the body.

Taking earth's inner temperature
A new study led by Woods Hole Oceanographic Institution (WHOI) suggests the mantle--the mostly solid, rocky part of Earth's interior that lies between its super-heated core and its outer crustal layer -- may be hotter than previously believed. The new finding, published March 3 in the journal Science, could change how scientists think about many issues in Earth science including how ocean basins form.

JILA team discovers many new twists in protein folding
Biophysicists at JILA have measured protein folding in more detail than ever before, revealing behavior that is surprisingly more complex than previously known. The results suggest that, until now, much about protein behavior has been hidden to science -- happening on faster timescales and with finer changes in structure than conventional methods could detect.

Understanding and predicting snow behavior
Engineers from the University of Luxembourg are developing a computer model that can help solving typical snow-related engineering problems. The model could, for example, be used to anticipate avalanches, to determine the load on buildings caused by snow or calculate the traction of vehicles on snow-covered surfaces by predicting the behavior of snow.

Ninety percent of predatory fish gone from Caribbean coral reefs due to overfishing
Researchers at the University of North Carolina at Chapel Hill have found that up to 90 percent of predatory fish are gone from Caribbean coral reefs, straining the ocean ecosystem and coastal economy. The good news? They identified reefs, known as supersites, which can support large numbers of predator fishes that if reintroduced, can help restore the environmental and economic setback inflicted by overfishing.

A better way to measure the stiffness of cancer cells
Biomedical engineers at Duke have discovered a way to detect signs of cancer on a cell-by-cell basis using two lasers and a camera. An increase in cell stiffness is an indicator of cancerous tissue, but current technology cannot gauge cells individually. In a study appearing online Feb. 28 in the Biophysical Journal, researchers describe a technique for assessing an individual cell's stiffness using patterns that appear within its internal structure.
