Astronomy Without A Telescope – Our Ageing Universe

It all started so full of promise. All at once, our universe burst upon the scene, but much of that initial burst quickly dissipated into background neutrinos and photons – and ever since, pretty much everything our universe has ever done has just dissipated more energy. So, despite the occasional enthusiastic outburst of supernovae and other celestial extravagances, it's becoming increasingly apparent that our universe is getting on a bit....

Could shaking batteries power gadgets?

What if you could recharge batteries simply by shaking them? Japan's Brother Industries thinks its prototype rechargeable batteries could shake up the gadget market.The juice is enough to power a remote control. By leaving the battery in a remote control and shaking it, the cell will be recharged. It's unclear how long (or vigorously) you'd have to shake it, but I doubt it would require shaking your fist at the TV for an entire episode of your most hated show.

June Global Temperatures Warmest on Record

Last month's combined global land and ocean surface temperature made it the warmest June on record, according to the National Oceanic and Atmospheric Administration, NOAA. The global temperature also broke the records for April-June and January-June time periods.
The monthly analysis from NOAA's National Climatic Data Center in Asheville is based on temperature records going back to 1880.
Each of the 10 warmest average global temperatures recorded since 1880 have occurred in the last 15 years. The warmest year-to-date on record, through June, was 1998, and 2010 is warmer so far, NOAA's climate scientists said.

Google Energy buys wind power in first deal

Google Energy has signed a deal to purchase 114 megawatts of energy from a wind farm in Iowa, marking the first deal done by Google's energy subsidiary. The deal is significant in that it's the first done by Google Energy, a subsidiary created in December last year. When news of Google Energy came out, there was a great deal of speculation as to why Google, which is active in renewable energy and efficiency, would want to operate a wholly-owned subsidiary.

Insulin Signaling Key to Caste Development in Bees

The study, which appeared in the June 30 online edition of Biology Letters, shows that a key protein in the insulin signaling pathway plays a strong role in caste development among bees.

A female bee can become either a worker or a queen. Queen bees are larger and live longer than workers. Queen bees are also fertile while workers are essentially sterile. A queen has only one role -- to lay eggs -- while workers tend the hive, care for the queen and larvae, and forage for food.

Deepwater Shark Diets Include Other Sharks

Deepwater sharks eat everything from commercial fishing vessel discards to other sharks.
Scavenging human discards can both benefit and hurt sharks, since some may become entangled in nets.One of the most extensive studies on the diets of deepwater sharks reveals these toothy animals may eat everything from discards tossed off commercial fishing vessels to other sharks.

The study, published in the journal Deep Sea Research, is the first such major investigation to utilize DNA sequencing and the Barcode of Life Database (BOLD) to identify prey found in the stomachs of deepwater sharks. Shark edibles are usually too digested or fragmented, but collected DNA can be matched to animals recorded in the database.

Solar Impulse completes first solar-powered night flight

A giant glider-like aircraft has completed the first night flight propelled only by solar energy.

Solar Impulse, whose wingspan is the same as an Airbus A340, flew 26 hours and 9 minutes, powered only by solar energy stored during the day. It was also the longest and highest flight in the history of solar aviation, organizers said.

Bertrand Piccard, the Swiss president of the project, best known for completing the first round-the-world flight in a hot air balloon in 1999, said the success of the flight showed the potential of renewable energies and clean technology.

Computer Simulations Show Oil Reaching Up the Atlantic Coastline and Toward Europe

The possible spread of the oil spill from the Deepwater Horizon rig over the course of one year was studied in a series of computer simulations by a team of researchers from the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaii at Manoa. The simulations suggest that the coastlines near the Carolinas, Georgia, and Northern Florida could see the effects of the oil spill as early as October 2010, while the main branch of the subtropical gyre is likely to transport the oil film towards Europe, although strongly diluted.

Dinosaurs Nestled Up to Geysers, Hot Springs to Incubate Eggs

In the Cretaceous period over a hundred million years ago, Argentina's Sanagasta Valley was alive with hydrothermal activity, much like Yellowstone National Park or Iceland are today. Tunnels of near-boiling, mineral-rich water crisscrossed the subsurface , and explosive geysers pockmarked the landscape. Doesn't seem like a very inviting place to raise a family.

But researchers found some 80 clutches of fossilized eggs in the area, many of them containing a dozen or more eggs each. Even more strange, the nests were almost exclusively found within 10 feet of a geyser or hot spring. It seems that far from avoiding the hydrothermal features, dinosaurs were purposefully laying eggs near them as a way to keep them incubated during their 1-2 month long gestation.
Gerald Grellet-Tinner of the Field Museum in Chicago and Lucas Fiorelli of CRILAR in Argentina published their findings in the journal Nature Communications

Coolest Stars:Brown Dwarfs

Astronomers have uncovered what appear to be 14 of the coldest stars known in our universe. These failed stars, called brown dwarfs, are so cold and faint that they'd be impossible to see with current visible-light telescopes. Spitzer's infrared vision was able to pick out their feeble glow, much as a firefighter uses infrared goggles to find hot spots buried underneath a dark forest floor.

New US satellite to monitor debris in Earth orbit

A new U.S. Air Force satellite,SBSS will provide the first full-time, space-based surveillance of hundreds of satellites and thousands of pieces of debris that could crash into American and allied assets circling the Earth.

If all goes as planned, the Space-Based Space Surveillance satellite, scheduled for a July 8 launch from Vandenberg Air Force Base, Calif., will have an unobstructed, around-the-clock view of the increasingly heavy traffic in Earth orbit — something the Air Force doesn't have now.

Currently, the Air Force relies on a ground-based network of radar and optical telescopes around the globe to monitor about 1,000 active satellites and 20,000 pieces of debris. The telescopes can be used only on clear nights, and not all radar stations are powerful enough to detect satellites in deep space orbit, about 22,000 miles from Earth.

Extinction of Woolly Mammoth May Have Been Caused by Human Predators

 A new analysis of the extinction of woolly mammoths and other large mammals more than 10,000 years ago suggests that they may have fallen victim to the same type of "trophic cascade" of ecosystem disruption that scientists say is being caused today by the global decline of predators such as wolves, cougars, and sharks. The cascading events were originally begun by human disruption of ecosystems, a new study concludes, but around 15,000 years ago the problem was not the loss of a key predator, but the addition of one -- human hunters with spears.
