1.Study sees fatalism behind some risky teen behavior (www.latimes.com)
Chicago -- Nearly 15% of teenagers think they are going to die young, leading many to drug use, suicide attempts and other unsafe behavior, new research suggests.
The study, based on a survey of more than 20,000 young people, challenges conventional wisdom that says teens engage in risky behavior because they think they are invulnerable to harm.
Instead, a sizable number of teens may take chances "because they feel hopeless and figure that not much is at stake," said study author Dr. Iris Borowsky, a researcher at the University of Minnesota.
That behavior threatens to turn their fatalism into a self-fulfilling prophecy.
Teens who thought they would die early were seven times more likely than optimistic teens to be subsequently diagnosed with AIDS. They also were more likely to attempt suicide and get in fights resulting in serious injuries.......

2.Click here to see this must see picture taken from space (apod.corank.com)
From 400 kilometers above planet Earth , the Expedition 20 Crew onboard the International Space Station ( ISS ) was able to witness a remarkable event from a remarkable vantage point -- the June 12 eruption of the Sarychev Peak Volcano . The active volcano is located in Russia's Kuril Island chain , stretching to the northeast of Japan. Emphasizing the orbital perspective, this stunning color stereo view was made by combining two images from the ISS and is intended to be viewed with red/blue glasses (red for the left eye). Punching upwards into the atmosphere at an early stage of the eruption, the volcanic plume features a brown column of ash topped with a smooth, bubble-like, white cloud that is likely water condensation. Below, a cloud of denser grey ash slides down the volcanic slope. About 1.5 kilometers of the island coastline is visible at ground level. The evolving ash plume posed no danger to the Expedition 20 crew, but commercial airline flights were diverted away from the region to minimize the danger of engine failures from ash intake.

3.Cells Use Import Machinery To Export Their Goods As Well (www.sciencedaily.com)
ScienceDaily (June 25, 2009) — In the bustling economy of the cell, little bubbles called vesicles serve as container ships, ferrying cargo to and from the port - the cell membrane. Some of these vesicles, called post-Golgi vesicles, export cargo made by the cell's protein factory. Scientists have long believed that other, similar vesicles handle the reverse function, importing life-supporting nutrients and proteins through an independent process........

4.Patriotic Music May Close Minds, Children's Music May Open Them (www.sciencedaily.com)
That's the focus of research by Kansas State University's Eduardo Alvarado, sophomore in pre-law, who is looking at the behaviors elicited from the musical lyrics of common songs.
Alvarado is working with Donald Saucier, associate professor of psychology at K-State to study the effects priming can have on behavior by looking at the positive and negative responses stimulated from music lyrics from a variety of song categories, including patriotic and Christmas songs. Priming, he said, is when someone is exposed to a certain environment and their subconscious is activated, and then they tend to act in accordance with that environment without deliberate intent. Priming can manipulate behavior; if someone witnesses violent behavior, they would likely behave more violently. -
5.Russian Scientists: H1N1 linked to Genetically Modified Food (www.prisonplanet.com)
Scientists from Russia’s Ministry of Health are warning in a secret report to Prime Minister Putin that they have discovered a ‘critical link’ between the H1N1 influenza (Swine Flu) virus and genetically modified amylopectin potatoes that are consumed in massive quantities nearly exclusively by Westerners and sold in fast food restaurants as French Fries........

6.Grains of Sand Reveal Possible Fifth State of Matter (www.wired.com)
In the formation of droplets in a stream of falling sand, scientists have witnessed a dynamic that points beyond the boundaries of traditional physics, and may represent one aspect of a fifth state of matter.
“Here we have a material right underneath our noses, that everybody grows up playing with in a sandbox, yet it’s full of surprises for scientists,” physicist said Heinrich Jaeger of the University of Chicago.
The droplets formed because of instabilities in the subtle atomic forces that attract sand grains to each other. Something similar happens to water falling from a faucet, but the forces acting on those molecules are 100,000 times stronger........

7.Spacefaring Bacteria (georgewashington2.blogspot.com)
In 2002, several scientists claimed that bacteria high in Earth's atmosphere came from space.
Last year, scientists said that bacteria in the upper atmosphere may actually make rain. Specifically, they said that bacteria can freeze at fairly warm temperatures, so that the "biological ice nuclei" form condensation nuclei which triggers rain.
Indeed, some scientists have speculated that bacteria cause rain as a means of transportation, so that they will "rain out" from the upper atmosphere to the surface of a planet........
