Producing a large scale, multi-venue, televised event is a huge challenge and certainly not an exact science. Flexibility, quality, dependability and diligence are necessary to pull it off. Brown United, an LA, CA based company specializing in temporary and permanent event construction, has a proven track record with companies such as AEG (Coachella/Stagecoach), for whom they are counted on year after year. Los Angeles, CA (PRWEB) January 25, 2012 It takes several days and thousands of man...

New Research Shows Feathered Dinosaur Could Fly
2012-01-25 06:22:05

[ Watch the Video ] An international team of researchers led by Brown University has shed some new light on whether the winged dinosaur Archaeopteryx could fly. The team has determined that a well-preserved feather on the raven-sized dinosaur's wing was black, which is evidence that the feathers had traits that could help Archaeopteryx fly. Also, the researchers determined that the fossilized feather's structure is identical to living birds, according to the research published in the...

Device Measures Glucose In Saliva

Engineers at Brown University have designed a biological device that can measure glucose concentrations in human saliva. The technique could eliminate the need for diabetics to draw blood to check their glucose levels. The biochip uses plasmonic interferometers and could be used to measure a range of biological and environmental substances. Results are published in Nano Letters. For the 26 million Americans with diabetes, drawing blood is the most prevalent way to check glucose levels. It...

Many High-risk Americans Don’t Get Hepatitis B Vaccine
2012-01-20 04:41:15

A recently published study investigating hepatitis B vaccination rates in the United States found that more than half of adults at risk for hepatitis B virus remain unvaccinated. With many of these individuals making contact with the healthcare system, including HIV testing, this statistic reflects many missed opportunities to vaccinate this population. Although there is an effective vaccine for hepatitis B and public health officials have a strong sense of who is at highest risk for the...

Mammalian Evolution Mirrors Climate Change
2011-12-27 05:39:51

A recent study by an international group of evolutionary biologists has pointed to six broad yet distinct ℠waves´ of climate-induced mammalian diversity in the last 65 million years of evolution. Researchers say that extended periods of warming and cooling appear to signal the shift from one dominant grouping of mammals to the next. In the online version of the journal The Proceedings of the National Academy of Sciences (PNAS), Professor Christine Janis of Brown University and a...

Primates learn from feedback that surprises them, and in a recent investigation of how that happens, neurosurgeons have learned something new. The insight they gleaned from examining the response of specific brain tissues during a learning task may inform future rehabilitative therapies after stroke or traumatic brain injury. "It's been known for a long time that it's unexpected events in particular that drive learning," said Wael Asaad, assistant professor of neurosurgery in the Warren...

Understanding mechanism may aid in development of infection-fighting drugs In the human world of manufacturing, many companies are now applying an on-demand, just-in-time strategy to conserve resources, reduce costs and promote production of goods precisely when and where they are most needed. A recent study from Indiana University Bloomington scientists reveals that bacteria have evolved a similar just-in-time strategy to constrain production of an extremely sticky cement to exactly the...

Chemists at Brown University have synthesized a new compound that makes drug-resistant bacteria susceptible again to antibiotics. The compound – BU-005 – blocks pumps that a bacterium employs to expel an antibacterial agent called chloramphenicol. The team used a new and highly efficient method for the synthesis of BU-005 and other C-capped dipeptides. Results appear in Bioorganic and Medicinal Chemistry. It´s no wonder that medicine´s effort to combat bacterial...

Physicists Set Strongest Limit On Mass Of Dark Matter
2011-11-25 04:21:29

Brown University physicists have set the strongest limit for the mass of dark matter, the mysterious particles believed to make up nearly a quarter of the universe. The researchers report in Physical Review Letters that dark matter must have a mass greater than 40 giga-electron volts. The distinction is important because it casts doubt on recent results from underground experiments that have reported detecting dark matter. If dark matter exists in the universe, scientists now have set the...

Wrinkles and folds are ubiquitous. They occur in furrowed brows, planetary topology, the surface of the human brain, even the bottom of a gecko's foot. In many cases, they are nature's ingenious way of packing more surface area into a limited space. Scientists, mimicking nature, have long sought to manipulate surfaces to create wrinkles and folds to make smaller, more flexible electronic devices, fluid-carrying nanochannels or even printable cell phones and computers. But to attain those...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
