New findings from a NASA-funded instrument have resolved a decades-old puzzle about a fog of low-energy x-rays observed over the entire sky. Thanks to refurbished detectors first flown on a NASA sounding rocket in the 1970s, astronomers have now confirmed the long-held suspicion that much of this glow stems from a region of million-degree interstellar plasma known as the local hot bubble, or LHB.

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.
DNA–protein conjugates can be used in diagnostic techniques, nanotechnology and other disciplines, but controlling the conjugation of these macromolecules can be a challenge. Scientists in Denmark have pioneered an easier method that makes it possible to direct the tagging of proteins with DNA to a particular site on the protein without genetically modifying the protein beforehand.
In 2006, DARPA launched a long-term project called CORONET, which sought to develop a cloud-based technology that could enable affordable, fast bandwidth and ensure the survival of cloud networks in the event of system-wide failures. After years of work, scientists from AT&T, IBM and Applied Communication Sciences have announced a proof-of-concept technology that reduces setup times for cloud-to-cloud connectivity from days to seconds.
A new stem cell discovery might one day lead to a more streamlined process for obtaining stem cells, which in turn could be used in the development of replacement tissue for failing body parts, according to Univ. of California, San Francisco scientists who reported the findings in Cell.
Reactions among minerals and organic compounds in hydrothermal environments are critical components of the Earth’s deep carbon cycle. They provide energy for the deep biosphere, and may have implications for the origins of life. However, very little is known about how minerals influence organic reactions. A team of researchers has demonstrated how a common mineral acts as a catalyst for specific hydrothermal organic reactions.
A powerful new tool that can help advance the genetic engineering of “fuel” crops for clean, green and renewable bioenergy, has been developed by researchers at the Joint BioEnergy Institute, a multi-institutional partnership led by Lawrence Berkeley National Laboratory. The researchers have developed an assay that enables scientists to identify and characterize the function of nucleotide sugar transporters.
Fifteen years ago, Massachusetts Institute of Technology professor John Essigmann and colleagues from the Univ. of Washington had a novel idea for an HIV drug. They thought if they could induce the virus to mutate uncontrollably, they could force it to weaken and eventually die out—a strategy that our immune system uses against many viruses.
A $1,000-per-pill drug that insurers are reluctant to pay for has quickly become the treatment of choice for a liver-wasting viral disease that affects more than three million Americans. In less than six months, prescriptions for Sovaldi have eclipsed all other hepatitis C pills combined, according to new data from IMS Health.
A powerful new tool that could help advance the genetic engineering of “fuel” crops bioenergy, has been developed by researchers with the Joint BioEnergy Institute. Their new, unique assay enabled them to analyze nucleotide sugar transporter activities in Arabidopsis, a promising source of plant biomass, and characterize a family of six nucleotide sugar transporters that has never before been described.
Big data can mean big headaches for scientists. A new library of software tools from Howard Hughes Medical Institute’s Janelia Research Campus speeds analysis of data sets so large and complex they would take days or weeks to analyze on a single workstation, even if a single workstation could do it at all. The new tool, Thunder, should help interpret data that holds new insights into how the brain works.
Physicists have identified the “quantum glue” that underlies a promising type of superconductivity—a crucial step towards the creation of energy superhighways that conduct electricity without current loss. The research, published online in the Proceedings of the National Academy of Sciences, is a collaboration between the Univ. of Illinois at Chicago, Cornell Univ. and Brookhaven National Laboratory.
Some chemical conversions are harder than others. Refining natural gas into an easy-to-transport, easy-to-store liquid alcohol has so far been a logistic and economic challenge.
