OU developing advanced radar for rapid updates and improved severe weather warnings
A team of engineers and meteorologists from the Advanced Radar Research Center located in the Radar Innovations Laboratory on the University of Oklahoma Research Campus will develop faster, more advanced imaging radar with a five-year, $3 million grant from the National Science Foundation. The C-band, mobile, polarimetric, imaging radar will provide simultaneous snapshots of a storm with unprecedented resolution and flexibility. The faster, more advanced imaging radar will lead to a better understanding of storms and provide improved severe weather warnings.

Intensity of desert storms may affect ocean phytoplankton
Scientists at MIT, Columbia University, and Florida State University have determined that once iron is deposited in the ocean, it has a very short residence time, spending only six months in surface waters before sinking into the deep ocean. This high turnover of iron signals that large seasonal changes in desert dust may have dramatic effects on surface phytoplankton that depend on iron.

A new technique to make drugs more soluble
Researchers from Harvard John A. Paulson School of Engineering and Applied Science have developed a new system that can produce stable, amorphous nanoparticles in large quantities that dissolve quickly. The system is so effective that it can produce amorphous nanoparticles from a wide range of materials, including for the first time, inorganic materials with a high propensity towards crystallization, such as table salt.

Political polarization on Twitter depends on the issue
Twitter offers a public platform for people to post and share all sorts of content, from the serious to the ridiculous. While people tend to share political information with those who have similar ideological preferences, new research from NYU's Social Media and Political Participation Lab demonstrates that Twitter is more than just an 'echo chamber.'

Evidence suggests subatomic particles could defy the standard model
A team of physicists working at CERN's Large Hadron Collider (LHC) has found new hints of particles -- leptons, to be more precise -- being treated in strange ways not predicted by the Standard Model. The discovery, scheduled for publication in the Sept. 4, 2015 issue of the journal Physical Review Letters, could prove to be a significant lead in the search for non-standard phenomena.

Historic 2013 Colorado Front Range storm accomplished up to 1,000 years of erosion
The historic September 2013 storm that triggered widespread flooding across Colorado's Front Range eroded the equivalent of hundreds, or even as much as 1,000 years worth of accumulated sediment from the foothills west of Boulder, researchers at the University of Colorado Boulder have discovered.

Stiffer breast tissue in obese women promotes tumors
Women who are obese have a higher risk and a worse prognosis for breast cancer, but the reasons why remain unclear. A Cornell study published this month in Science Translational Medicine explains how obesity changes the consistency of breast tissue in ways that are similar to tumors, thereby promoting disease.

The membranes of sediment-entombed archaea are an increasingly popular way to determine ocean surface temperatures back to the age of the dinosaurs. But new results show that changing oxygen can affect the reading by as much as 21 degrees C.

Home sweet microbe: Dust in your house can predict geographic region, gender of occupants
The humble dust collecting in the average American household harbors a teeming menagerie of bacteria and fungi, and as researchers from the University of Colorado Boulder and North Carolina State University have discovered, it may be able to predict not only the geographic region of a given home, but the gender ratio of the occupants and the presence of a pet as well.

These microscopic fish are 3-D-printed to do more than swim
Nanoengineers at the University of California, San Diego used an innovative 3-D printing technology they developed to manufacture multipurpose fish-shaped microrobots -- called microfish -- that swim around efficiently in liquids, are chemically powered by hydrogen peroxide and magnetically controlled. These proof-of-concept synthetic microfish will inspire a new generation of 'smart' microrobots that have diverse capabilities such as detoxification, sensing and directed drug delivery, researchers said.

Sequencing of barley genome achieves new milestone
Barley, a widely grown cereal grain commonly used to make beer and other alcoholic beverages, possesses a large and highly repetitive genome that is difficult to fully sequence. Now a team led by scientists at the University of California, Riverside has reached a new milestone in its work, begun in 2000, on sequencing the barley genome. The researchers have sequenced large portions of the genome that together contain nearly two-thirds of all barley genes.

Rare nautilus sighted for the first time in 3 decades
In early August, biologist Peter Ward returned from the South Pacific with news that he encountered an old friend, one he hadn't seen in over three decades. The University of Washington professor had seen what he considers one of the world's rarest animals, a remote encounter that may become even more infrequent if illegal fishing practices continue.

Foes can become friends on the coral reef
On the coral reef, knowing who's your friend and who's your enemy can sometimes be a little complicated. Take seaweed, for instance. Normally it's the enemy of coral, secreting toxic chemicals, blocking the sunlight, and damaging coral with its rough surfaces. But when hordes of hungry crown-of-thorns sea stars invade the reef, everything changes, reports a study published Aug. 25 in the journal Proceedings of the Royal Society B.

Researchers tackle issues surrounding security tools for software developers
For software programmers, security tools are analytic software that can scan or run their code to expose vulnerabilities long before the software goes to market. But these tools can have shortcomings, and programmers don't always use them. New research from National Science Foundation-funded computer science researcher Emerson Murphy-Hill and his colleagues tackles three different aspects of the issue.

NSF grant enables University of Akron polymer scientist to engineer noses, jaws and ears
Imagine an infantry solder with a gunshot wound that shattered his jaw, or a person born with a birth defect such as a missing nose. The absent bone is replaced by new bone, which grows on a polymer scaffold custom-designed via 3-D printing according to a patient's own MRI and CT scanned images. Applied under the skin by a reconstructive surgeon, the polymer scaffold breaks down into normal body metabolites when the new bone sets.

UMD-led study identifies the off switch for biofilm formation
When disease-causing bacteria establish a biofilm on hospital equipment, it can be impossible to sterilize the devices, raising infection rates and necessitating expensive replacements. Now, a University of Maryland-led team has found an enzyme that shuts down the signals bacteria use to form a biofilm. The findings, reported in the Aug. 24, 2015 Early Online Edition of the Proceedings of the National Academy of Sciences, could one day help make biofilm-related complications a distant memory.
