Modular acoustic filters simplify design of mufflers, musical instruments, audio tags
Designing acoustic filters that can block out a certain sound or produce a certain pitch can be hit or miss, but researchers have discovered a way to predict acoustic qualities 70,000 times faster than current algorithms, paving the way for new, computationally driven designs.

Oceanographers grow, sequence genome of ocean microbe important to climate change
A University of Washington team has shed new light on a common but poorly understood bacteria known to live in low-oxygen areas in the ocean. By culturing and sequencing the microbe's entire genome, the oceanographers found that it significantly contributes to the removal of life-supporting nitrogen from the water in new and surprising ways.

Scientists glimpse inner workings of atomically thin transistors
With an eye to the next generation of tech gadgetry, a team of physicists at The University of Texas at Austin has had the first-ever glimpse into what happens inside an atomically thin semiconductor device. In doing so, they discovered that an essential function for computing may be possible within a space so small that it's effectively one-dimensional.

Columbia Engineering researchers use acoustic voxels to embed sound with data
Columbia Engineering, Disney Research, and MIT researchers have developed a method to control sound waves, using a computational approach to inversely design acoustic filters that fit within an arbitrary 3-D shape while achieving target sound filtering properties. They designed acoustic voxels, small, hollow, cube-shaped chambers through which sound enters and exits, as a modular system. Like LEGOs, the voxels can be connected to form a complex structure and can modify the structure's acoustic filtering property.

Computational design tool transforms flat materials into 3-D shapes
A new computational design tool can turn a flat sheet of plastic or metal into a complex 3-D shape, such as a mask, a sculpture or even a lady's high-heel shoe. Researchers at Carnegie Mellon University and the Swiss Federal Institute of Technology in Lausanne, Switzerland, say the tool enables designers to fully and creatively exploit an unusual quality of certain materials -- the ability to expand uniformly in two dimensions.

Scientists cut 'Gordian knot' in the human genome
Females have two X chromosomes in each of their cells. Fully unfolded, each copy is two inches long. One of these two X chromosomes is inactive -- its genes are turned off. This copy folds into a structure called the Barr body, a mysterious configuration that was discovered in 1949. Recently, scientists have shown the Barr body contains massive superloops bringing DNA sequences at opposite ends of the chromosome together inside the nucleus of a cell.

Researchers create means to monitor anthropogenic global warming in real time
A research team simulated in a computer model, for the first time, the realistic evolution of global mean surface temperature since 1900. The researchers also created a new method by which scientists can measure and monitor the pace of anthropogenic global warming, finding that the contribution of human activities to warming in the surface waters of the Pacific Ocean can be distinguished from natural variability.

Lemur DNA paints a picture of Madagascar's forested past
While there's no question that human activities such as logging and slash-and-burn agriculture have dramatically altered Madagascar's forests since the first settlers arrived about 2,000 years ago, just how much of the island was forested before people got there remains a matter of debate. Now, a DNA study of tree-dwelling mouse lemurs suggests that humans did not arrive to find the island as blanketed by forests as frequently assumed.
