DURHAM, N.C., April 19, 2011 /PRNewswire/ -- Lend Lease, through its legacy Bovis Lend Lease business, has been awarded Duke University's West Campus Steam Plant Renewal and Conversion project. The original West Campus Steam Plant was constructed in 1929, and has undergone various modifications. This project consists of removal of three existing coal-fired boilers and replacing with new boilers that will allow Duke to burn either natural gas or oil, along with controls, electrical and...

Using eyes made of a calcium carbonate crystal, a simple mollusk may have evolved enough vision to spot potential predators, scientists say. The three-inch-long mollusks, called chitons, have hundreds of eye-like structures with lenses made of aragonite, a type of rock. It's the first time scientists have found an animal that makes eye lenses from aragonite and not the rock's close cousin, calcite. "It's surprising how these creatures make their eyes from rocks," said Duke biologist...

The number of endangered leatherback sea turtle nests at 68 beaches in Florida has increased by 10.2 percent a year since 1979, according to a new Duke University-led study published in the current issue of the journal Ecological Applications.Some beaches posted annual increases of more than 16 percent, others as low as 3.1 percent.The population boom of turtle nests in the Sunshine State mirrors trends observed for other Atlantic leatherback sea turtle populations and is "very encouraging...

Study of 27,000 trees shows early spring warming, summer drought as major factorsAn 18-year study of 27,000 individual trees by National Science Foundation (NSF)-funded scientists finds that tree growth and fecundity--the ability to produce viable seeds--are more sensitive to climate change than previously thought.The results, published tomorrow in the journal Global Change Biology, identify earlier spring warming as one of several factors that affect tree reproduction and growth. They also...

A research team from Duke University in North Carolina has recreated autistic mice by mutating the gene which controls production of the protein, Shank3. The single protein may trigger autistic spectrum disorders by disrupting communication between brain cells, BBC News is reporting. Autism affects the ability of children and adults to communicate and interact socially and has varying degrees of severity. Hundreds of genes linked to the condition have been found. However the precise...

(Ivanhoe Newswire)"” From overworked professionals to over-extended students, everyone worries about how much sleep they're getting. A new study from Duke University has shown yet another consequence of not sleeping enough: sleep deprivation can lead to a more optimistic outlook, resulting in riskier decisions. Using a functional MRI, scientists showed that a lack of sleep increases brain activity in the brain regions that assess positive outcomes while decreasing activity in the...

The powers that be in Las Vegas figured out something long before neuroscientists at two Duke University medical schools confirmed their ideas this week: Trying to make decisions while sleep-deprived can lead to a case of optimism. The scientists showed, using a functional MRI, that a night of sleep deprivation leads to increased brain activity in brain regions that assess positive outcomes, while at the same time this deprivation leads to decreased activation in the brain areas that process...

Humans share 98.7 percent of our DNA with chimpanzees, but we share one important similarity with one species of chimp, the common chimpanzee, that we don't share with the other, the bonobo. That similarity is violence. While humans and the common chimpanzee wage war and kill each other, bonobos do not. "There has never been a recorded case in captivity or in the wild of a bonobo killing another bonobo," notes anthropologist Brian Hare. Hare is an assistant professor in evolutionary...

A Duke University team has seen for the first time how soft polymers, such as wire insulation, can break down under exposure to electrical current.Researchers have known for decades that polymers, such those insulating wires, may break down due to deformation of the polymers. But the process had never been seen.In a series of experiments, Duke University engineers have documented at the microscopic level how plastic deforms to breakdown as it is subjected to ever-increasing electric voltage....


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
