(PhysOrg.com) — UQ neuroscientists have, for the first time, been able to demonstrate that moderate exercise significantly increases the number of neural stem cells in the ageing brain.
In research published in Stem Cells, Dr Daniel Blackmore and his colleagues at the Queensland Brain Institute (QBI) have shown that moderate exercise directly increases the number of stem cells in the ageing brain.
Despite the conventional wisdom that we only have a set number of neurons or brain cells, neuroscientists have known for some time that, in healthy brains, the creation of new neurons is an ongoing and lifelong mechanism.
However, it has also been known for more than a decade that the number of new neurons we produce slowly declines with age.
According to QBI neuroscientist Dr Blackmore, researchers are interested in finding ways to stimulate the production of neurons to negate any decline brought about by age or disease.
“Our findings suggest that moderate exercise, from early to late in life, can have a very positive effect,” Dr Blackmore said.
In controlled models of ageing, the number of neural stem cells produced by animals participating in voluntary exercise (running wheel) were significantly higher than in animals of the same age which did not exercise (no running wheel).
“Investigating the mechanism by which neural stem cell numbers are altered will undoubtedly increase our understanding of how the brain responds to its environment,” Dr Blackmore said.
“Ultimately, this should allow us to discover how to harness the brain’s regenerative capacity, and to bring about new and effective treatments for conditions caused by trauma, disease, or even normal ageing.”
“The brain’s ability, even at an advanced age, to respond in a positive manner is very exciting as it extends the time-frame in which manipulation is possible.”
QBI Director Professor Perry Bartlett FAA said the research represented another significant understanding of the why neural stem cells were so important to brain function.
“It is the first experimental data that shows how we can change the propensity of the brain to make new neurons through increasing the number of stem cells – even in the aged animal,” Professor Bartlett said.
“We can now show that exercise directly causes an increase in the number of stem cells in the brain.
“Stem cells develop into neurons and a good supply of neurons is essential for good mental health,” he said.
The research paper “Exercise increases neural stem cell number in a GH-dependent manner, augmenting the regenerative response in aged mice” by Dr Daniel Blackmore, Dr Mohammad Golmohammadi, Beatrice Large, Dr Michael Waters and Dr Rodney Rietze appeared in the 14 May online edition of Stem Cells.

We’re more than 262,031 members strong in California

Did You Know?

  • California is the leading producer of renewable energy in the United States. It ranks 1st in the nation for solar PV, solar thermal, geothermal, and bio-power capacity.It also ranks 3rd in the nation for installed wind capacity.
  • California is home to the largest single source of solar energy in the world: a 354 MW solar thermal facility in the Mojave Desert.The state will shatter its own record in 2011 when a 553 MW solar thermal facility built by Solel begins operation, also in the Mojave Desert.According to researchers at the National Renewable Energy Laboratory, California’s total solar thermal potential is equal to 12 times the state’s current electricity capacity.
  • California’s potential geothermal resources can power every home in the state.The state’s potential unconventional geothermal resources could power another 54 million homes.

Clean energy jobs in California

California is at the forefront of electricity generation from non-hydroelectric renewable energy sources, and its policies and investments encourage strong job growth in a clean energy economy. A few companies are already taking part in this new economy by providing ‘green’ jobs.

For example, FPL Group is set to operate its 250-megawatt solar thermal energy plant near Kern County, which will employ roughly 1,000 workers in its operation. And reports estimate that more jobs could be on the way. One study says that $12.7 billion investment on deploying renewable energy and energy efficiency in the Golden State can create 235,000 jobs over two years. And, this study only captures a portion of the service, construction, and technology jobs that will be created in the state by truly Repowering America.

(AP) — On a steep slope of the Rogue River-Siskiyou National Forest, a crew of young men with chain saws and hardhats worked their way through an old neglected clearcut, cutting brush and young trees and piling the remains to be burned later.

Freshly trained and closely supervised, the crew took care to leave behind volunteer sproutings of dogwood, madrone and huckleberry as well as the sugar pine and Douglas fir planted here 20 years ago. The pattern is designed to grow into a healthy forest less vulnerable to wildfire and better for fish and wildlife, rather than just turn out timber.

The House Hope Stewardship Project, taken off the shelf with $1.4 million from President Barack Obama’s , will thin and restore 890 acres.

It’s a tiny fraction of the 60 million to 80 million acres the U.S. Forest Service estimates need it nationwide, but people here feel as if this is a start – not only to grappling with the growing threat of wildfire in a warming climate, but in healing rifts between environmentalists, the timber industry and the Forest Service that have left the national forests in limbo.

“I wouldn’t go so far as to say there is peace in the valley, but we are closer than ever before,” said Shane Jimerfield, director of the Siskiyou Project, a local  group that grew out of the protests.

The national forests of the Northwest became a crucial national lumber source after World War II when the baby boom fueled a huge demand for new houses. But by the 1980s scientists began to worry that species like the northern spotted owl and some salmon were headed for extinction due to a loss of habitat.

Environmentalists won court orders stopping that logging, and the Clinton administration came up with the Northwest Forest Plan in 1994, which cut logging by more than 80 percent and set aside huge areas for fish and wildlife habitat. After President George W. Bush was elected in 2000 his administration tried to dismantle the Northwest Forest Plan and increase logging but was repeatedly blocked by more court rulings.

Please join Mendocino Area Parks Association’ s Carolyne Cathey and other park supporters and visitors 1:00PM today – Saturday June 20 – at 1:00PM beside the Ford House on Mendocino Headlands. The issues may not be clear to all of us, and this is your chance to hear what is going on with the state parks funding and how critical our voices are right now.
Enjoy some music and stop in the Ford House for a tour of this historic house on the headlands.

The only hope we have left to keep the parks open is to encourage all the voters in the state to contact their Senators, Representatives, and the Governor and ask for their “Yes” vote on a new funding stream to support our state parks — a $15/year per vehicle State Park Access Pass added to our car registrations. The Republican Caucus in both the Senate and the House, and the Governor, oppose this concept. With a SPAP, any of us with a California registered vehicle will have free day use, no matter how many times we entered the Parks.

To her credit, Assemblywoman Patty Wiggins not only supports funding for state parks, but she had already taken a salary cut, and reduced her per diem reimbursement for living expenses in Sacramento. Senator Wes Chesbro is also a strong support of parks.

Without some funding mechanism in this budget round, Parks will close. Businesses will be hurt when visitors stop coming because the campgrounds are closed, the restrooms are locked, the litter piles up and the roads are barricaded. Park properties will suffer right here where we live
and all over the state.

Please come and listen, and lend your support to help keeps our
parks open.

I am only a member of one MCN community list, Fort Bragg. If you would be so kind, we would appreciate it if you would send this message to the other local community lists as well.

Thank you,

'Milking' microscopic algae could yield massive amounts of oilEnlarge

Scientists in Canada and India are proposing a surprising new solution to the global energy crisis —“milking” oil from the tiny, single-cell algae known as diatoms, renowned for their intricate, beautifully sculpted shells that resemble fine lacework. Their report appears online in the current issue of the ACS’ bi-monthly journal Industrial Engineering & Chemical Research.

Richard Gordon, T. V. Ramachandra, Durga Madhab Mahapatra, and Karthick Band note that some geologists believe that much of the world’s crude oil originated in diatoms, which produce an oily substance in their bodies. Barely one-third of a strand of hair in diameter, diatoms flourish in enormous numbers in oceans and other water sources. They die, drift to the seafloor, and deposit their shells and oil into the sediments. Estimates suggest that live diatoms could make 10−200 times as much oil per acre of cultivated area compared to oil seeds, Gordon says.

“We propose ways of harvesting oil from diatoms, using biochemical engineering and also a new solar panel approach that utilizes genetically modifiable aspects of biology, offering the prospect of “milking” diatoms for sustainable energy by altering them to actively secrete oil products,” the scientists say. “Secretion by and milking of diatoms may provide a way around the puzzle of how to make that both grow quickly and have a very high content.”

From Foreign Policy Magazine an interesting look at the implications and historical contest of our current econ0mic situation;

“AS NIKOLAI KONDRATIEV SHIVERED before his executioners on a wintry Siberian morning in 1938, he could scarcely have imagined that, 71 years later, his name would be resurrected by a new generation of business theorists and management gurus seeking to understand the first Great Recession of the 21st century.

A prime mover behind Lenin’s 1921 New Economic Policy, which briefly rehabilitated capitalism in order to save a young Soviet Union from imminent collapse, Kondratiev was an intellectual insurgent in a time and place where heresy could get one killed. Kondratiev theorized that economic activity took place in long waves: 50- or 60-year periods of creativity and growth followed by briefer contractions, after which the cycle would begin anew.

So taken was Joseph Schumpeter, the Harvard University economist best known for coining the term “creative destruction,” with the idea of long waves that he named the concept for Kondratiev. Schumpeter’s view was that innovation tends to arrive in clumps: “discrete rushes which are separated from each other by spans of comparative quiet.” These bursts of creativity, he wrote, “periodically reshape the existing structure of industry by introducing new methods” of production, organization, and supply. As for the negative effects of depressions—unemployment, the loss of wealth, economic dislocation—they were just creative destruction at work.”

Fire Mitigation Work In Western US Misplaced, Says New Study

ScienceDaily (June 15, 2009) — Only 11 percent of wildfire mitigation efforts undertaken as a result of a long-term federal fuels-reduction program to cut down catastrophic wildfire risk to communities have been undertaken near people’s homes or offices in the past five years, says a new study led by the University of Colorado at Boulder.

The analysis of the U.S. National Fire Plan shows that as more Americans live in or near fire-prone forests and more wildfires burn, most federally funded activities to reduce fuels and wildfire hazard have occurred far from the “wildland-urban interface,” the area prioritized by federal wildfire policies. The result suggests that federal wildfire treatments are minimally effective at mitigating the threat of wildfire to homes and people in the western United States.

The study also suggests that future fire mitigation strategies should emphasize constructing and maintaining “firewise” homes, restricting the abundance and configuration of residential housing units near wildlands susceptible to fire, and improving cooperation among private and public landowners in implementing fire mitigation treatments and in paying for fire suppression.

“Our comprehensive analysis suggests that fire mitigation treatments do not effectively target the wildland-urban interface,” said Tania Schoennagel, a research scientist in CU-Boulder’s geography department.

Schoennagel led a team of researchers who examined 44,000 federally funded wildfire mitigation projects in 11 western states between 2004 and 2008.

Schoennagel’s team is the first to evaluate the U.S. National Fire Plan’s management activities across the West, and to compare the location of fire-mitigation treatments to the wildland-urban interface and its nearby surroundings. The team’s findings will be published in the June 8 edition of the Proceedings of the National Academy of Sciences.

Co-authors on the study included CU-Boulder graduate student Teresa Chapman, the University of Montana’s Cara Nelson and Gunner Carnwath and Colorado State University’s David Theobald. The study was funded by the National Science Foundation and the Wilburforce Foundation.

The team found that only 11 percent of fuel-reduction activities took place within about 1.5 miles of the wildland-urban interface, where fires pose the greatest risk to homes and people. At the same time, most of the treated land was more than 6 miles from this high-risk zone.
