Tsunami + 1 year: Reviving exhausted fisheries should trump replacing boats, gear, experts say

...cation programs are much needed to revive severely exhausted fisheries and steer survivors into more sustainable livelihoods than fishing. According to new analyses by the Malaysia-based WorldFish Centre (see ? Rebuilding Boats May Not Equal Rebuilding Livelihoods and ? Rehabilitating Livelihoods in Tsunami-A...

Sahara's edge studied from ground, air and space to improve water management

...s levels, but its deep-level fossil water has been exhausted in many places. A Dornier Do-228 aircraft flown by the German Aerospace Center (DLR) was the platform for two airborne sensors operating simultaneously: the Experimental Synthetic Aperture Radar (E-SAR) built by DLR, which can acquire imagery at dif...

A more powerful and efficient engine for rice: the C3-C4 challenge

... of the world's poor. "Frankly, we have almost exhausted the traditional methods of increasing rice production, especially considering the environmental challenges we face such as climate change," IRRI Director General Robert Zeigler said. "This generation must work to assure food security not only for our...

How HIV 'exhausts' killer T cells

...ing the PD-1 pathway could restore the function of exhausted killer T cells. "We wanted to determine whether these T cells had been irreparably damaged or misprogrammed," he said. "And we found that they are capable of functioning; they've just been turned off." Similarly, the researchers also found that...

Protowings may have helped bird ancestors cover rough terrain

...preference to flying to gain elevated terrain, and exhausted birds always resort to WAIR. Dial and colleagues describe experiments showing that if the surface area of chukar wings is reduced by plucking or trimming the feathers, WAIR becomes less effective for climbing slopes. Dial and colleagues propose that...

Chronic jet-lag conditions hasten death in aged mice

.... The findings may not come as a great surprise to exhausted globe-trotting business travelers, but the research nonetheless provides, in rather stark terms, new insight into how the disruption of circadian rhythms can impact well-being and physiology, and how those impacts might change with age. The mouse stu...

Switching genes to overdrive improves muscular dystrophy symptoms in mice

...ily on both days, while untreated MDX rodents were exhausted halfway through each run. The MDX mice with increased PGC-1alpha activity performed almost as well as normal mice on the first day; their performances decreased on the second day, but they still did better than the untreated MDX mice on both runs. ...
