Scientists at Consiglio Nazionale delle Ricerche in Italy have discovered particles of cocaine and marijuana in the air around Rome, they revealed today.
Rome's atmosphere contained 0.1 nanograms per cubic meter of cocaine at its height during their analysis. Not a substantial impact but still a cause for concern. This was in addition to benzopyrene C20H12 and other types of emissions.
Evidence for an awesome upheaval in a massive galaxy cluster was discovered in an image made by NASA’s Chandra X-ray Observatory. The origin of a bright arc of ferociously hot gas extending over two million light years requires one of the most energetic events ever detected.
The cluster of galaxies is filled with tenuous gas at 170 million degree Celsius that is bound by the mass equivalent of a quadrillion, or 1,000 trillion, suns. The temperature and mass make this cluster a giant among giants.
In a night sky filled with hungry bats, good-tasting moths increase their chances of survival by mimicking the sounds of their bad-tasting cousins, according to a new Wake Forest University study.
The study is the first to definitively show how an animal species uses acoustic mimicry as a defensive strategy. The research was conducted by Jesse Barber, a doctoral student in biology at Wake Forest. William E. Conner, professor of biology at Wake Forest, co-authored the study.
It seems almost certain that San Francisco Giants slugger Barry Bonds will pass Hank Aaron as baseball’s all-time home-run king sometime this summer, but his pursuit has generated little public interest.
There may be several reasons for this, ranging from Bonds’ prickly personality to the suspicion that he may have used performance-enhancing drugs later in his career, say two Duke University professors.

A fascinating new paper from the June issue of Current Anthropology explores ancient multiple graves and raises the possibility that hunter gatherers in what is now Europe may have practiced ritual human sacrifice.
This practice – well-known in large, stratified societies – supports data emerging from different lines of research that the level of social complexity reached in the distant past by groups of hunter gatherers was well beyond that of many more recent small bands of modern foragers.
Sound waves escaping the sun's interior create fountains of hot gas that shape and power a thin region of the sun's atmosphere which appears as a ruby red "ring of fire" around the moon during a total solar eclipse, according to new research.
McDonald's new advertising campaign to promote high-level career opportunities within the company is a great way to fight the connotation of dead-end drudgery and low wages that comes with "McJobs," according to Jerry M. Newman, SUNY Distinguished Teaching Professor in the University at Buffalo School of Management.
Having worked undercover at seven fast-food restaurants across the United States, including McDonald's, Burger King and Wendy's, Newman, author of "My Secret Life on the McJob," says that McDonald's has the right idea in its newest television commercial.
While heavy drinking has consistently been linked to an increased risk of intimate partner violence (IPV), a new study has found that both drinking patterns and neighborhood characteristics can contribute in different ways to mutual IPV among married/cohabiting adults in the general population.
Results are published in the June issue of Alcoholism: Clinical & Experimental Research.
Certain army ants in the rainforests of Central and South America conduct spectacular predatory raids containing up to 200,000 foraging ants. Remarkably, some ants use their bodies to plug potholes in the trail leading back to the nest, making a flatter surface so that prey can be delivered to the developing young at maximum speed.Specialization by a minority can help the greater good.

Plasma astrophysicists at the University of Warwick have found that key information about the Sun’s 'storm season’ is being broadcast across the solar system in a fractal snapshot imprinted in the solar wind. This research opens up new ways of looking at both space weather and the unstable behaviour that affects the operation of fusion powered power plants.
When the movie Spider-Man 3 swung into theaters a few weeks ago, it found University physics professor James Kakalios waiting. A diehard fan of superhero comics, he takes a double interest in Spidey foe Sandman, who can transform all or part of his body into living sand.
The use of 12 tone intervals in the music of many human cultures is rooted in the physics of how our vocal anatomy produces speech, according to researchers at the Duke University Center for Cognitive Neuroscience.
An extraordinary underwater trackway with 12 consecutive prints provides the most compelling evidence to-date that some dinosaurs were swimmers. The 15-meter-long trackway, located in La Virgen del Campo track site in Spain's Cameros Basin, contains the first long and continuous record of swimming by a non-avian therapod dinosaur.
When Dutch astronomer Willem de Sitter proposed a static model of the universe in the early 1900s, he was some 3 trillion years ahead of his time.
Researchers have found that bricks made from fly ash--fine ash particles captured as waste by coal-fired power plants--may be even safer than predicted. Instead of leaching minute amounts of mercury as some researchers had predicted, the bricks apparently do the reverse, pulling minute amounts of the toxic metal out of ambient air.
