Researchers found that, in areas with higher levels of pollution, there were more medications dispensed for psychiatric conditions in children and teens, compared with areas with lower levels of pollution. "The results can mean that a decreased concentration of air pollution — first and foremost, traffic-related air pollution — may reduce psychiatric disorders in children and adolescents," lead study author Anna Oudin, a public health researcher at Umeå University in Sweden, said in a statement.

Read More » Stegosaurus had bite like a sheep Professor Paul Barrett, dinosaur researcher at London's Natural History Museum, said advanced technology has given exciting new insights into dinosaur biology - something that would not have been possible several years ago. "Stegosaurus was actually an animal that could get up to 9 metres in length and weigh several tonnes," Barrett said while holding a Stegosaurus tooth. Lead author Dr Stephan Lautenschlager, a post-doctoral researcher at the University of Bristol, used engineering software to give the digital skulls the material properties to match as closely as possible to the real thing.

(Reuters) - An unmanned cargo ship pulled away from the International Space Station on Tuesday to stage the first of three planned NASA experiments on how big fires grow in space, an important test for astronaut safety. Previous experiments in space were limited to the incineration of samples no bigger than an index card, said David Urban, lead researcher for the Spacecraft Fire Experiment, or Saffire. "We tried for years to find a vehicle and a circumstance where this would work and initially we'd get a 'not on my spacecraft' reaction," Urban said during a NASA TV interview.

(Reuters) - Scientists for the first time have found a complex organic molecule in space that bears the same asymmetric structure as molecules that are key to life on Earth. The researchers said on Tuesday they detected the complex organic molecule called propylene oxide in a giant cloud of gas and dust near the center of the Milky Way galaxy. Akin to a pair of human hands, certain organic molecules including propylene oxide possess mirror-like versions of themselves, a chemical property called chirality.

	(Sponsor this newsletter) Scientists use climate, population changes to predict diseases By Kate Kelland LONDON (Reuters) - British scientists say they have developed a model that can predict outbreaks of zoonotic diseases – those such as Ebola and Zika that jump from animals to humans – based on changes in climate. "Our model can help decision-makers assess the likely impact (on zoonotic disease) of any interventions or change in national or international government policies, such as the conversion of grasslands to agricultural lands," said Kate Jones, a professor who co-led the study at University College London's genetics, evolution and environment department. Around 60 to 75 percent of emerging infectious diseases are so-called "zoonotic events", where animal diseases jump into people.

For Mensa, the exclusive international society comprising members of "high intelligence," someone who scores at or above the 98th percentile on an IQ or other standardized intelligence test could be considered genius. In his new science series "Genius" on PBS, Stephen Hawking is testing out the idea that anyone can "think like a genius." By posing big questions — for instance, "Can we travel through time?" — to people with average intelligence, the famed theoretical physicist aims to find the answers through the sheer power of the human mind. "It's a fun show that tries to find out if ordinary people are smart enough to think like the greatest minds who ever lived," Hawking said in a statement. Read More » Filling the Periodic Table: New Names for the Newest Elements The new names were announced Wednesday (June 8) by the International Union of Pure and Applied Chemistry (IUPAC), the organization that standardizes chemical element names. The endings of each of the proposed names (such as –ium) reflect the element's place in the periodic table. The rest of the name is specific to each element's discovery, according to a statement that IUPAC issued in recommending the new names. Read More » 'Smart' Blocks Turn Lego Creations into Web-Connected Toys The new devices, from Israel-based Brixo Smart Toys, use chrome-plated blocks that conduct electricity to connect batteries with electronics. "The human body resists electrical currents from passing though it — it has a high electrical resistance," said Brixo founder Boaz Almog, a quantum physicist at Tel Aviv University. Read More » Shock and Awe: Eels Leap to Deliver Electrifying Attacks In a "shocking" turn of events, a researcher has discovered that electric eels can intensify their electrical attacks by leaping from the water to make physical contact with animals that threaten them, according to a new study. The finding provides support for a famous but previously contested observation of a dramatic interaction between electric eels and horses dating back to 1800. When 19th-century naturalist Alexander von Humboldt set out to collect electric eels in South America, local fishermen introduced him to the concept of "fishing with horses" — herding 30 hapless horses into the eels' pool to sap their electrical charges so the eels could be gathered safely. Read More » Long-Term Marijuana Use Linked to Changes in Brain's Reward System People who use marijuana for many years respond differently to natural rewards than people who don't use the drug, according to a new study. Researchers found that people who had used marijuana for 12 years, on average, showed greater activity in the brain's reward system when they looked at pictures of objects used for smoking marijuana than when they looked at pictures of a natural reward — their favorite fruits. "This study shows that marijuana disrupts the natural reward circuitry of the brain, making marijuana highly salient to those who use it heavily," study author Dr. Francesca Filbey, an associate professor of behavioral and brain science at the University of Texas at Dallas, said in a statement.

	(Sponsor this newsletter) CO2 Gets Stoned: Method Turns Harmful Gas Into Solid Essentially, they relied on a sped-up version of natural processes to take the carbon dioxide (CO2) spewed from a power plant in Iceland and transform the gas into a solid. This ability to capture carbon dioxide and store it indefinitely may help curb the levels of heat-trapping gases in the atmosphere and stem global warming, the researchers noted. "We need to deal with rising carbon emissions," lead study author Juerg Matter, now an associate professor of geoengineering at the University of Southampton in the United Kingdom, said in a statement. Read More » Leading British scientists warn leaving EU will hurt funding A group of Britain's most eminent scientists have endorsed the campaign for the UK to remain in the European Union, saying that leaving could damage research. In a letter to The Daily Telegraph, published on Saturday, 13 Nobel Laureates including John Gurdon, Peter Higgs and Paul Nurse said the EU allows scientists to move freely and collaborate in ways that would be lost if Britain votes to quit the 28-member bloc. The scientists also say that European funding would be cut if Britain voted to pull out of the 28-member EU.

The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived at New York's John F. Kennedy International Airport at about 4 a.m. local time after it took off about five hours beforehand at Lehigh Valley International Airport in Pennsylvania, the team reported on the airplane's website. "Such a pleasure to land in #NYC! For the 14th time we celebrate sustainability," said the project's co-founder Andre Borschberg on Twitter after flying over the city and the Statue of Liberty during the 14th leg of the trip around the globe.
