As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water that is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell. A Univ. of Washington researcher made the first study of waves in the middle of the Arctic Ocean, and detected house-sized waves during a September 2012 storm.
Media and marketing experts have long sought a reliable method of forecasting responses from the general population to future products and messages. According to a study conducted at the City College of New York in partnership with Georgia Tech, it appears that the brain responses of just a few individuals are a remarkably strong predictor.
The best way to cure most cases of cancer is to surgically remove the tumor. The Achilles heel of this approach, however, is that the surgeon may fail to extract the entire tumor, leading to a local recurrence. With a new technique based on injectable dye and infrared light, researchers in Pennsylvania have established a new strategy to help surgeons see the entire tumor in the patient, increasing the likelihood of a positive outcome.
A hidden hazard lurks beneath many of the roughly 156,000 gas stations across the U.S. The hazard is corrosion in parts of underground gas storage tanks. In recent years, field inspectors in nine states have reported many rapidly corroding gas storage tank components such as sump pumps.
Stop sunbathing and using indoor tanning beds, the acting U.S. surgeon general warned in a report released Tuesday that cites an alarming 200% jump in deadly melanoma cases since 1973. The report blames a generation of sun worshipping for the $8 billion spent to treat all forms of skin cancer each year.
Some people can handle stressful situations better than others, and it’s not all in their genes: Even identical twins show differences in how they respond. Researchers have identified a specific electrical pattern in the brains of genetically identical mice that predicts how well individual animals will fare in stressful situations. The findings may eventually help researchers prevent potential consequences of chronic stress.
Tough, ultra-light foam of atom-thick sheets can be made to any size and shape through a chemical process invented at Rice Univ. In microscopic images, the foam dubbed “GO-0.5BN” looks like a nanoscale building, with floors and walls that reinforce each other. The structure consists of a pair of 2-D materials: floors and walls of graphene oxide that self-assemble with the assistance of hexagonal boron nitride platelets.
A team of researchers has created a new way of manufacturing microstructured surfaces that have novel 3-D textures. These surfaces, made by self-assembly of carbon nanotubes, could exhibit a variety of useful properties—including controllable mechanical stiffness and strength, or the ability to repel water in a certain direction.
Corning Inc. has donated $1.8 million in high-tech components for a telescope a private group wants to launch into space. The not-for-profit BoldlyGo Institute wants to put its ASTRO-1 telescope in orbit by the mid-2020s. The group says obtaining the components for a roughly 6-ft telescope primary mirror marks a major step toward the ambitious goal.
A new study has investigated the effects of small but finite inertia on the propulsion of micro- and nano-scale swimming machines. Scientists have found that the direction of propulsion made possible by such inertia is opposite to that induced by a viscoelastic fluid. The findings could help to optimize the design of swimming machines to improve their mobility in medical applications.
An affordable digital reading system invented by researchers in Australia now allows people who are blind to read more than just words. The device works by using pattern recognition technology and other methods on any document to identify images, graphs, maths or text. From here it is then converted to audio format with navigation markup.
Bruker has announced that it has acquired Vutara Inc., a technology leader in high-speed, 3-D, super-resolution fluorescence microscopy for life science applications. Transaction details were not disclosed. Vutara’s estimated revenue for the full year 2014 is expected to be approximately $2 million.
TE Connectivity has announced the launch of its new Deutsch Autosport Heavy Duty (ASHD) 3-Way Connector. The new connector was designed for the growing hybrid market in motorsports, in which racecars use three-phase motor/generator systems.
Ophir Photonics Group has announced the USB option for StarLite, the company's low cost, handheld laser power/energy meter. The USB option allows StarLite to communicate directly with a PC via USB and allows the meter to display all measurements on StarLab 3.0 laser measurement software.
Norwegian explorer Roald Amundsen became the first man to reach the South Pole in December 1911. More than 100 years later, an international team of scientists that includes a NASA researcher has proven that air pollution from industrial activities arrived to the planet’s southern pole long before any human.
