]]>NASA Spitzer Telescope celebrates 10 years in space!
Ten years ago the Spitzer Space Telescope was launched about a Delta II rocket from Canaveral, Florida. Spitzer is an infrared telescope and is the fourth of the NASA’s four Great Observatories in space, Hubble, Chandra, Compton and Spitzer.
Precision atomic clock sets new record
The most precise clocks in the world have been built in the US. Two clocks made from ytterbium (serioulsy I’ve not heard of this element before!) and could be used for technological advancements beyond timekeeping, such as navigation systems, magnetic fields and temperature. Apparently the clocks’ ticking rate varies less than two parts in one quintillion, or 10 times better than any other atomic clock. Sounds great! But does it stop me being late for work?
NASA prepares for LADEE launch
The Lunar Atmosphere and Dust Environment Explorer (LADEE) is a robotic mission that will orbit the moon to gather detailed information about the structure and composition of the thin lunar atmosphere and determine whether dust is being lofted into the lunar sky. LADEE will help us better understand the moon, and other objects including asteroids and other planetary moons.
Want to boost your testosterone level? Try chopping wood…
A new study by the Institute of Social, Behavioural and Economic Research at the University of California, Santa Barbara has found that chopping wood to clear land and feed the family produces more testosterone in men than competitive activities like sport.
Plankton may spread oyster herpes virus
Plankton may be spreading a herpes-like virus that has been devastating Pacific oyster farms in countries ranging from France, UK, Spain and the US.
Bacteria can cause pain on their own
Bacteria can directly trigger the nerves that sense pain, suggesting that the body’s own immune reaction is not always to blame for the extra tenderness of an infected wound.
Map tracks path of dust plume from Russian Chelyabinsk meteor
Watch this video that shows the dust path left behind the 11,000-metric-ton meteor as it ripped through Earth’s atmosphere on February 15, 2013.

]]>Welcome to this edition of Weekly Science Picks.
What a busy news week – with the markets up, the transportation incidents with planes and trains, major flooding in China…well, there’s been a lot going on. And there were numerous stories of scientific importance reported on as well. So I’ve listed the stories I’ve found significant this week. Topics include climate change, space, physics, public health, girls in education, and dogs watching TV. Yes, dogs watching TV. There’s a little something for everyone. So kick back, with your favorite beverage in hand and soak up some knowledge.
TOP STORIES
Distant quakes ‘can trigger wastewater-site temblors’ by Jason Palmer
The notion of natural earthquake triggering is not new; in hydrothermal and volcanic areas, tremors can be triggered by large, distant earthquakes. But the new study suggests what is in effect a new category: natural triggering of seismic events primed by human activity.
If you’d like to read the full paper, you can check it out on Science: Injection-Induced Earthquakes by William L. Ellsworth
NASA Warned to Go Slow On Asteroid Capture Project by Richard A. Kerr
NASA’s plan to retrieve a tiny asteroid as a steppingstone for astronauts on the way to Mars in the 2030s could be just the exciting project that the space agency needs to garner public support in these severe budgetary times, speakers at a workshop held yesterday in Washington, D.C., said.
Climate Change Will Cause More Energy Breakdowns, U.S. Warns by John M. Broder
Every corner of the country’s energy infrastructure — oil wells, hydroelectric dams, nuclear power plants — will be stressed in coming years by more intense storms, rising seas, higher temperatures and more frequent droughts.
NEWS TO BE AWARE OF
ScienceShot: Sterilizing Human Waste, No Electricity Required by Lizzie Wade
Thanks to a new invention, all you need is some sunshine, a little water, and a dash of gold nanoparticles.
Optical lattice atomic clock could ‘redefine the second’ by Rebecca Morelle
The devices, called optical lattice clocks, lost just one second every 300 million years – making them three times as accurate as current atomic clocks.
At UN, Malala Yousafzai rallies youth to stand up for universal education by UN News Centre
“Let us pick up our books and our pens. They are our most powerful weapons. One teacher, one book, one pen, can change the world,
