A lightweight, comfortable jacket that can generate the power to light up a jogger at night may sound futuristic, but materials scientist Trisha Andrew at UMass Amherst could make one today. In a new paper this month, she and colleagues outline a way to apply breathable, pliable, metal-free electrodes to fabric and off-the-shelf clothing so it feels good to the touch and also transports enough electricity to power small electronics.
Researchers have succeeded in permanently rewriting flatworms' regenerative body shape by resetting their internal bioelectric pattern memory, causing even normal-appearing flatworms to harbor the 'code' to regenerate as two-headed worms.
Significant commercial investment in wearable vision systems for personal communications and entertainment is driving rapid advances in miniature optoelectronics components and consumer-driven applications. A special section in this month's issue of Optical Engineering, published by SPIE, the international society for optics and photonics, aims to help boost progress across development in automotive, industrial, and military applications.
Northwestern University scientists have built a structurally complex material from two simple building blocks that is the lowest-density metal-organic framework ever made. Directed by design rules developed by the scientists, uranium atoms and organic linkers self-assemble into a beautiful crystal -- a large, airy 3-D net of very roomy and useful pores. The pores are so roomy, in fact, that the scientists have nestled a large enzyme inside a pore -- no small feat.
Researchers at the Wyss Institute have engineered a model of human pulmonary thrombosis using its Organ-on-a-Chip platform that mimics in vivo blood clot formation and confirms the transmission of inflammatory signals from the pulmonary epithelium to the vascular endothelium, providing a new model for investigation and treatment/prevention of pulmonary blood clots.
Researchers from Princeton University's Department of Molecular Biology have identified a small RNA molecule that helps maintain the activity of stem cells in both healthy and cancerous breast tissue. The study, which will be published in the June issue of Nature Cell Biology, suggests that this 'microRNA' promotes particularly deadly forms of breast cancer and that inhibiting the effects of this molecule could improve the efficacy of existing breast cancer therapies.
A team of plant biologists and biochemists has produced a gold mine of data by sequencing the genome of a tiny, single-celled green alga that could be used as a source of sustainable biofuel and has health implications.
Some NASA missions fundamentally change the world of science or help win Nobel prizes, but only one saves thousands of lives worldwide every year.
An international research team has found a 3.3 million Australopithecus afarensis fossilized skeleton, possessing the most complete spinal column of any early fossil human relative. The vertebral bones, neck and rib cage are mainly intact. This new research, published today in the Proceedings of the National Academy of Science demonstrates that portions of the human skeletal structure were established millions of years earlier than previously thought.
First launched in 1977 as as means to quickly disseminate the latest in optics research and provide the optics and photonics community with a true Letters-style publication, Optics Letters has, over the course of its long history, published influential papers in nonlinear optics, ultrafast spectroscopy, fiber optics, optical communication, and biomedical optics among other areas. This year the Journal celebrates its 40th anniversary and The Optical Society (OSA) has launched a special website to highlight this milestone.
