Astronomers have caught their first glimpse of the invisible magnetic fields that sculpt solar systems. Looking at a bright, nearby baby star and the dust swirling in its cradle, astronomers from the Univ. of Illinois and six collaborating institutions were able to make out the shape of the magnetic field surrounding the star.
As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption. With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation.
Given today’s widespread use of Raman spectroscopy, it can be hard to believe Raman was a highly specialized analytical technique for most of its history. The technique’s potential was recognized from the beginning: When Raman scattering was first observed in 1928, it was widely believed to be one of the most important scientific discoveries of the 20th century to date.
An unmanned commercial supply rocket bound for the International Space Station exploded moments after liftoff Tuesday evening, with debris falling in flames over the launch site in Virginia. No injuries were reported following the first catastrophic launch in NASA's commercial spaceflight effort.
In the on-going effort to develop advanced biofuels as a clean, green and sustainable source of liquid transportation fuels, researchers at the U.S. Dept. of Energy’s Joint BioEnergy Institute have identified microbial genes that can improve both the tolerance and the production of biogasoline in engineered strains of Escherichia coli.
Rice Univ. researchers have delivered a scientific one-two punch with a pair of papers that detail how synthetic collagen fibers self-assemble via their sticky ends. Collagen is the most common protein in mammals, a major component of bone and the fibrous tissues that support cells and hold organs together. Discovering its secrets may lead to better synthetic collagen for tissue engineering and cosmetic and reconstructive medicine.
If the majority of light-duty vehicles in the U.S. ran on higher-octane gasoline, the automotive industry as a whole would reduce its carbon dioxide emissions by 35 million tons per year, saving up to $6 billion in fuel costs, according to a new analysis by Massachusetts Institute of Technology researchers.
U.S. health officials are recommending that people who are at highest risk for coming down with Ebola avoid commercial travel or attending large public gatherings, even if they have no symptoms. The Centers for Disease Control and Prevention issued the updated advice to state and local officials on Monday.
As a laboratory technician or director, knowing the current status of your instrument or sample runs is critical for your laboratory’s operations and productivity. Through the rapid increase in machine-to-machine connectivity, real-time instrument monitoring services designed to offer visibility and remote control of these instruments has become an enabler in cost savings, efficiency gains, revenue opportunities and competitive advantage.
Like a slumbering dragon, HIV can lay dormant in a person’s cells for years, evading medical treatments only to wake up and strike at a later time, quickly replicating itself and destroying the immune system. Scientists at the Salk Institute have uncovered a new protein that participates in active HIV replication. The new protein, called Ssu72, is part of a switch used to awaken HIV-1 from its slumber.
In early drug discovery, you need a starting point. In a new research paper published in PLOS-Neglected Tropical Diseases, a team of researchers present hundreds of such starting points for potentially treating Human African trypanosomiasis, or sleeping sickness, a deadly disease that affects thousands of people annually.
Lasers are so deeply integrated into modern technology that their basic operations would seem well understood. CD players, medical diagnostics and military surveillance all depend on lasers. Re-examining longstanding beliefs about the physics of these devices, Princeton Univ. engineers have now shown that carefully restricting the delivery of power to certain areas within a laser could boost its output by many orders of magnitude.
The governors of New York and New Jersey are at odds with scientists over Ebola as they back 21-day quarantines for medical workers returning from West Africa, while the nation's top infectious-disease expert warns that such restrictions are unnecessary and could discourage volunteers from aiding disease-ravaged countries.
Traditional forms of temperature measurement, such as thermocouples and spot pyrometers, often don’t offer the resolution or speed required to fully characterize high-speed thermal applications. This article explores the advantages of high-speed thermal measurement with infrared cameras.
In many areas of the developing world, there’s limited access to electricity, and many places have never had any type of power infrastructure. This presents a challenge for aid workers and doctors. In the recent past, vaccines that needed to be stored at cold, relatively constant temperatures couldn’t be taken into the remote areas where they were needed most.
Certain quantum physical phenomena in matter can only be clearly visualized in the presence of extreme magnetic fields. Physicists in Germany are developing a new high field magnet based on a hybrid design conceived in the U.S. On Oct. 16, 2014, scientists with the High Field Magnet project reported consistent magnetic fields of 26 T, higher than 25-T goal originally conceived.
Sandia National Laboratories has begun laboratory-based characterization of TransPower’s GridSaver, the largest grid energy storage system analyzed at Sandia’s Energy Storage Test Pad in Albuquerque. Sandia will evaluate the 1 MW, lithium-ion grid energy storage system for capacity, power, safety and reliability. The laboratory also will investigate the system’s frequency regulation.
When a solid material is immersed in a liquid, the liquid immediately next to its surface differs from that of the bulk liquid at the molecular level. This interfacial layer is critical to our understanding of a diverse set of phenomena. When the solid surface is charged, it can drive further changes in the interfacial liquid. However, elucidating the molecular structure at the solid-liquid interface under these conditions is difficult.
New achievements in synthetic biology, which will allow complex cellular recognition reactions to proceed outside of living cells, will dare scientists to dream big: There could one day be inexpensive, shippable and accurate test kits that use saliva or a drop of blood to identify specific disease or infection.
The AN/AAR-57 Common Missile Warning System (CMWS) helps protect Army aircraft from attack by shoulder-launched missiles and other threats. To keep this defensive system operating at maximum effectiveness, the Army periodically updates the software on the more than 1,000 AN/AAR-57 units in use around the world.
Though it garners few headlines, carbonic acid, the hydrated form of carbon dioxide, is critical to both the health of the atmosphere and the human body. However, because it exists for only a fraction of a second before changing into a mix of hydrogen and bicarbonate ions, carbonic acid has remained an enigma. A new study has yielded new information about carbonic acid with important implications for geological and biological concerns.
When studying extremely fast reactions in ultra-thin materials, two measurements are better than one. A new research tool invented by researchers at Lawrence Livermore National Laboratory (LLNL), Johns Hopkins Univ. and NIST captures information about both temperature and crystal structure during extremely fast reactions in thin-film materials.
Nature has developed a wide variety of methods for guiding particular cells, enzymes and molecules to specific structures inside the body: White blood cells can find their way to the site of an infection, while scar-forming cells migrate to the site of a wound. But finding ways of guiding artificial materials within the body has proven more difficult.
Developing invisible implantable medical sensor arrays, a team of Univ. of Wisconsin-Madison engineers has overcome a major technological hurdle in researchers’ efforts to understand the brain. The team described its technology, which has applications in fields ranging from neuroscience to cardiac care and even contact lenses, in Nature Communications.
Measuring oil content in wastes is nothing new to the petrochemical industry. Whether it’s produced water from onshore or offshore sites, effluents from refineriers or drill cuttings and drilling mud, limits on hydrocarbon levels need to be met. With the increase of hydraulic fracturing in the U.S., more public attention has been focused on the need for regulations and limits.
