NRL scientists study cracks in brittle materials

Researchers used computer modeling and experimentation to investigate how cracks grow at low speeds in silicon, finding rearrangements of atoms associated with ductile materials can occur near the crack tip. This instability can lead to macroscopic changes in the path of the crack, leaving behind ridges on the crack surface.

Mystery behind the strongest creature in the world

Researchers studied the beetle's shell using advanced imaging techniques to understand its color-changing property. The study found that the light interferes with the structure to produce the green color, and when water penetrates, it destroys the interference phenomenon leading to a black coloration.

Nanotechnology provides 'green' path to environmentally sustainable economy

A new report from the Project on Emerging Nanotechnologies explores the potential of nanotechnology to build an environmentally sustainable society. The report highlights several promising applications, including the use of nanoparticles to clean up toxic waste sites and reduce lead emissions in electronics manufacturing.

Erotic images elicit strong response from brain

Researchers found that women's brains responded with stronger electrical activity when viewing erotic images than non-erotic content, regardless of its pleasantness or disturbance level. The study suggests that the brain processes erotic material differently, potentially due to evolutionary factors.

Printable silicon for ultrahigh performance flexible electronic systems

Researchers at University of Illinois have developed a technique to print single-crystal silicon objects onto flexible plastics, enabling high-performance thin-film transistors. This approach separates silicon processing from component fabrication, allowing for integration with various materials and large-area formats.

Sandia/UNM self-assembly process forms durable nanocrystal arrays and independent nanocrystals

Researchers at Sandia National Laboratories and the University of New Mexico developed a simple method to form durable nanocrystal arrays using a self-assembly process. The arrays can be used for biological labeling, laser light, catalysts, memory storage, and relief for physicists. The technique also enables the creation of independen...

New scheduling method raises efficiency of electronics recycling

Researchers at Purdue University have developed a new scheduling method for electronics recycling that optimizes the flow of incoming products from storage to disassembly. By prioritizing large products with quick disassembly times, recyclers can reduce storage space needs by up to half and increase productivity.

Appreciation of humor doesn't change with age

A Canadian study found that appreciation and emotional reactiveness to humor doesn't change with age. However, the ability to comprehend more complex forms of humor diminishes in later years due to decreased cognitive abilities. Older adults still enjoy a good laugh but struggle with understanding nuanced humor.

A rare find

Scott Oliver has been awarded a $500,000 NSF career grant to develop a new class of cationic microporous inorganic materials with unprecedented potential applications. These materials can trap anionic pollutants and are stable under high temperatures or acidic/basic conditions.

Diamond in the rough...and on the chip

Researchers at the University of Wisconsin-Madison have developed a stable, DNA-modified diamond film that can detect biological molecules with high accuracy. The sensor, which is about the size of a postage stamp, has the potential to be used in early warning systems for defense against biological weapons.
