Farmer-led irrigation schemes could alter food security in sub-Saharan Africa, South Asia
As food prices escalate globally due to the failed monsoon season in Asia and the "super drought" in the US, a new study finds that small-scale irrigation schemes can protect millions of farmers from food insecurity and climate risks in sub-Saharan Africa and South Asia. The International Water Management Institute (IWMI), a CGIAR consortium research center, released the paper ahead of Stockholm World Water Week.

Wind concentrates pollutants with unexpected order in an urban environment
Cities â€" with their concrete canyons, isolated greenery, and congested traffic â€" create seemingly chaotic and often powerful wind patterns known as urban flows. Carried on these winds are a variety of environmental hazards, including exhaust particles, diesel fumes, chemical residues, ozone, and the simple dust and dander produced by dense populations.

Seismometer tested for use on the Moon and Mars
(Phys.org)â€"Time and again, local quakes occur on the moon. Knowledge of their origin and intensity is required for the safe construction of moon bases for astronauts or for drawing conclusions with respect to the inner structure of the moon. To study moonquakes and the effects of gravitation accelerations, a set of several seismometers is planned to be installed on the surface of the moon during the SELENE2 Japanese moon mission.

SpaceX's next cargo run to space station in October
SpaceX is scheduled to launch the first of its 12 contracted cargo flights to the International Space Station in October, 2012. NASA Administrator Charles Bolden announced Thursday at Kennedy Space Center that SpaceX is now fully certified to ferry cargo to the space station. While the company's Dragon capsule did bring cargo to the ISS during its initial flight in May, that was considered just a test flight. Now comes a series of 'real' cargo runs.

How planetary resource's asteroid search could help find exoplanets
Planetary Resources is the private company that wants to eventually mine asteroids for profit. But initially, the group will focus on developing Earth orbiting telescopes to scan for the best asteroids, and then later, create low-cost robotic spacecraft for surveying missions and then actual spacecraft to do the mining.

The Webb Telescope's 'Golden Spider'
What looks like a giant golden spider weaving a web of cables and cords, is actually ground support equipment, including the Optical Telescope Simulator (OSIM), for the James Webb Space Telescope. OSIM's job is to generate a beam of light just like the one that the real telescope optics will feed into the actual flight instruments. Because the real flight instruments will be used to test the real flight telescope, their alignment and performance first have to be verified by using the OSIM. Engineers are thoroughly checking out OSIM now in preparation for using it to test the flight science instruments later.

Epic struggle between birds and pigs goes on with a Martian twist
NASA is helping pigs and birds explore the Martian terrain and shed light on the agency's missions to the Red Planet in the latest update to the game Angry Birds Space. Rovio Entertainment, creator of Angry Birds, announced the update Thursday, complete with a cast of agency rovers and landers.

New study maps Himalayan glacier behaviour
Glaciers are one of the largest reservoirs of freshwater on our planet, and their melting or growing is one of the best indicators of climate change. However, knowledge of glacier change has been hampered by lack of data, especially for understanding regional behaviour.   Measurements from satellites have recently provided the first overview mapping of thickness changes of Himalayan glaciers. In a study published in Nature today, scientists assembled new datasets from Earth-observing satellites and found that glaciers in the Hindu Kushâ€"Karakoramâ€"Himalaya region (HKKH) lost 12 gigatonnes per year over the period 2003â€"08, much faster than previously reported.

Good news from the bad drought: Gulf 'Dead Zone' smallest in years

Scientists explain scale of Japanese tsunami
Scientists at Cambridge University have developed a model that may show why some tsunamisâ€"including the one that devastated Japan in March 2011arâ€"e so much larger than expected.

ChemCam laser first analyses yield beautiful results
Members of the Mars Science Laboratory Curiosity rover ChemCam team, including Los Alamos National Laboratory scientists, squeezed in a little extra target practice after zapping the first fist-sized rock that was placed in the laser's crosshairs last weekend.

New satellite data on melting of Himalayan glaciers
(Phys.org)â€"There is consensus among scientists that the glaciers in the Himalayas and Tibet are shrinking, but there is disagreement on the extent of the shrinkage because of the difficulty in interpreting satellite data. In 2010 satellite data from the Gravity Recovery and Climate Experiment (GRACE) satellite was analyzed and the researchers concluded the glaciers were losing around 50 billion tonnes of ice each year, but the same data was interpreted earlier this year by another team of researchers who concluded the annual loss of ice was around five billion tonnes.

Repairing cartilage with fat: Problems and potential solutions
Stem cells isolated from fat are being considered as an option for treating tissue damage and diseases because of their accessibility and lack of rejection. New research published in BioMed Central's open access journal Stem Cell Research & Therapy shows that this is not as straightforward as previously believed, and that fat-derived stem cells secrete VEGF and other factors, which can inhibit cartilage regeneration. However pre-treating the cells with antibodies against VEGF and growing them in nutrients specifically designed to promote chondrocytes can neutralize these effects.

A Mediterranean diet rich in olive oil may protect your bones
New research suggests that a key ingredient to keeping osteoporosis in check may be found in the traditional Mediterranean dietâ€"olive oil.

This disease is considered to be one of the most common, debilitating and costly chronic diseases in Europe. This is why the results of the Spanish research group are important. The results of their study are to be published in the Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM), in which they show that consumption of a Mediterranean diet enriched with olive oil for two years is associated with increased serum osteocalcin concentrations, suggesting a protective effect on bone.

Biology news

The end of an era? Branding horses does not enable them to be identified
There are many reasons why it is important to be able to identify farm animals, horses and small companion animals. Unique identification marks are essential for ensuring the correctness of breeding programmes, for preventing the spread of disease and for eliminating the possibility of deceit in competitions or when animals are sold. The traditional method of marking larger farm animals relies on branding with hot irons or on ear-tagging but this is deemed inappropriate for use on dogs and cats, which are identified by the implant of a microchip transponder. Until recently, horses were generally branded but following concerns that the practice is unnecessarily cruel there has been a gradual switch towards the use of microchips. Branding has essentially been discontinued in the European Union, although several countries still accept it and breed registries claim that this traditional method is perfectly satisfactory and obviates the need for costly equipment.

For juvenile moose, momma's boys and girls fare best
Based on ten years of fieldwork in the Tetons of Wyoming, WCS Conservation Biologist, University of Montana Professor and study author Dr. Joel Berger looked at whether body size of juvenile moose and maternal presence were related to survival of the young animals. In animals from elk to lizards and fish, size matters, and larger individuals enjoy a survival advantage. However, results of Berger's study showed that for juvenile moose, body mass had no significant effect on overwinter survival. Maternal presence did.

New model gives hands-on help for learning the secrets of molecules
For biology researchers, the complex world of molecular proteins â€" where tens of thousands of atoms can comprise a single protein â€" may be getting clearer with the help of a new soft, transparent, and squishy silicone model they can hold in their hands. Its advantage over traditional computer and solid models is that it is mostly transparent and easy to manipulate, which will help researchers more intuitively understand protein structures, positions, and interactions.
