Eight Years And 34 Million Miles On, Mars Rover Nears End Of Road -- The Independent

It travelled at an average speed of 60cm an hour and it has arrived a year late. But the Mars rover Opportunity is finally approaching its destination, the rim of the vast Endeavour crater.

Nasa hailed the six-wheel Opportunity's approach to the 22.5km-wide crater last night as a "tremendous scientific success".

The ageing robotic field geologist has logged more than 32km since it was first parachuted on to the planet's surface in 2003, along with its twin rover Spirit, for a planned three-month mission after their 34 million-mile journey from Earth. Spirit emitted its last signal a year ago after becoming trapped in sand. Opportunity crawled out from a crater in 2008 and headed south to the Endeavour, a two-year journey in theory, which has taken longer because Opportunity had to drive backwards to prevent its front wheel from wearing out.

Sun Unleashes Largest Solar Flare In Five Years

Sun Unleashes Largest Solar Flare In Five Years, Sending 10Billion Ton Storm Cloud Hurtling Through Space At 5Million MPH -- Daily Mail

The sun unleashed an unusually powerful solar flare yesterday, the largest in nearly five years.

The eruption launched a ten billion ton storm cloud hurtling through space at five million miles per hour.

Scientists said the event took place on the side of the sun that was not facing Earth, so there will be little impact to satellites and communication systems.

My Comment: 10 billion tons .... that certainly makes one feel very small.

Antimatter Belt Around Earth Discovered By Pamela Craft -- BBC

A thin band of antimatter particles called antiprotons enveloping the Earth has been spotted for the first time.

The find, described in Astrophysical Journal Letters, confirms theoretical work that predicted the Earth's magnetic field could trap antimatter.

The team says a small number of antiprotons lie between the Van Allen belts of trapped "normal" matter.

The researchers say there may be enough to implement a scheme using antimatter to fuel future spacecraft.

Working In An Office Is Bad For Your Brain -- The Telegraph

Working in an office is bad for your brain and can make you less productive, according to researchers.

A study has found that the hustle and bustle of modern offices can lead to a 32% drop in workers well being and reduce their productivity by 15%.

They have found that open plan offices create unwanted activity in the brains of workers that can get in the way of them doing the task at hand.

Open plan offices were first introduced in the 1950s and quickly became a popular as a way of laying out offices.

Having a clean and sterile desk can also leave employees with smaller brains, scientists claim.

My Comment: I have to agree .... I was always more productive when I was not faced with distractions .... which an open plan office will provide.

Is Music A Powerful Antidepressant?

Making Music Proves To Be Powerful Antidepressant -- Live Science

Making music might help lift more depressed people out of the dumps than common antidepressant medications do, the results of a new study suggest.

That's not to say the people with depression should toss out their meds and pick up a guitar. The music therapy administered to patients in the new study was in addition to regular therapy, and the patients continued their regular medication routines. But about one out of four depression sufferers is likely to respond to music therapy, Finnish researchers reported in August in the British Journal of Psychiatry. In comparison, a 2009 review of research published in the journal Cochrane Database Systemic Review found that doctors must treat between seven and 16 people with tricyclic antidepressant drugs for one person to see improvement.

Nigeria's Oil Pollution Will Take Decades To Clean-Up

Nigeria Ogoniland Oil Clean-Up 'Could Take 30 Years -- BBC

Nigeria's Ogoniland region could take 30 years to recover fully from the damage caused by years of oil spills, a long-awaited UN report says.

The study says complete restoration could entail the world's "most wide-ranging and long-term oil clean-up".

Communities faced a severe health risk, with some families drinking water with high levels of carcinogens, it said.

Oil giant Shell has accepted liability for two spills and said all oil spills were bad for Nigeria and the company.

Where Did Humans Learn To Walk? -- Cosmos/AFP

PARIS: Grasslands dominated the cradle of humanity in east Africa longer and more broadly than thought, a new study has said, bolstering the idea that the rise of such landscapes shaped human evolution.

According to the so-called 'savannah hypothesis', the gradual transition from dense forests into grasslands helped drive the shift toward bipedalism, increased brain size and other distinctively human traits.

Engineers Solve Longstanding Problem in Photonic Chip Technology: Findings Help Pave Way for Next Generation of Computer Chips -- Science Daily

ScienceDaily (Aug. 5, 2011) — Stretching for thousands of miles beneath oceans, optical fibers now connect every continent except for Antarctica. With less data loss and higher bandwidth, optical-fiber technology allows information to zip around the world, bringing pictures, video, and other data from every corner of the globe to your computer in a split second. But although optical fibers are increasingly replacing copper wires, carrying information via photons instead of electrons, today's computer technology still relies on electronic chips.

Warfare Started With The Creation Of Man's First Nation States

PLUNDER Ruins at Monte Alban in Oaxaca, Mexico. A wave of new research holds that early states arose from warring chiefdoms as populations grew. Beth Greenfield for The New York Times

Sign of Advancing Society? An Organized War Effort -- New York Times

Some archaeologists have painted primitive societies as relatively peaceful, implying that war is a reprehensible modern deviation. Others have seen war as the midwife of the first states that arose as human population increased and more complex social structures emerged to coordinate activities.

A wave of new research is supporting this second view. Charles Stanish and Abigail Levine, archaeologists at the University of California, Los Angeles, have traced the rise of the pristine states that preceded the Inca empire. The first villages in the region were formed some 3,500 years ago. Over the next 1,000 years, some developed into larger regional centers, spaced about 12 to 15 miles apart. Then, starting around 500 B.C., signs of warfare emerged in the form of trophy heads and depictions of warriors, the two archaeologists report in last week’s Proceedings of the National Academy of Sciences.

My Comment: Economic cooperation or warfare .... the two underlying mechanisms that has always dictated how nation states behaved. It seems we have not changed much in 5,000+ years.

Atlantic Cod Recovering

East Coast Cod Found To Be Recovering -- CBC

New evidence shows that Atlantic cod off Nova Scotia are recovering from their dramatic collapse two decades ago — and that the ecosystem is recovering with them.

That suggests major changes to marine ecosystems can be reversed with time, says a Canadian study published Wednesday in the scientific journal Nature.

It also "bodes well" for other cod populations further north along the East Coast that have yet to recover, says the study, led by researcher Kenneth Frank at the Bedford Institute of Oceanography in Dartmouth, N.S.

Boeing Chooses A Rocket, Looks For Astronauts To Fly On It -- MSNBC

Atlas 5 to be used for tests of new spaceship for NASA's use; pilots wanted.

Test flights of The Boeing Co.'s future crew-carrying spaceship would be conducted starting as early as 2015 on United Launch Alliance's Atlas 5 rocket, executives announced Thursday.

Whether Boeing's CST-100 capsule actually flies in that timeframe depends on whether NASA provides the necessary development funding, said John Elbon, the aerospace company's manager for the commercial crew project. But just in case, Boeing is already looking for pilots who could help with the design and testing of the craft.
