Climate change: The rice genome to the rescue

...crops less productive with increasing temperatures decreasing yields. "Clearly, climate change is going to have a major impact on our ability to grow rice," Robert S. Zeigler, IRRI director general, said. "We can't afford to sit back and be complacent about this because rice production feeds almost half the wo...

Amazonian terra preta can transform poor soil into fertile

...agement also can reduce environmental pollution by decreasing the amount of fertilizer needed, because the bio-char helps retain nitrogen in the soil as well as higher levels of plant-available phosphorus, calcium, sulfur and organic matter. The black soil also does not get depleted, as do other soils, after re...

Mice studies illustrate potential of chimp/human antibodies to protect against smallpox

... minimum effective dose. Groups of mice were given decreasing doses--90, 45 and 22.5 micrograms per mouse--of 8AH8AL or a single 5-mg dose of human VIG (two and a half times the recommended human dose on a weight basis) as a point of comparison. All five mice in the control group died or were sacrificed when th...

Pittsburgh researchers discover that certain chemicals in the blood may indicate brain injury

Spring migration of pink-footed geese under threat

...hanged environment. We are already seeing signs of decreasing annual breeding success and decreased summer survival as a result of poor body condition when the geese depart from the spring staging areas. Our model shows that naïve geese have much lower fitness than experienced geese, which are able to anticipat...

Forsyth scientists gain greater understanding of how embryos differentiate left from right

...alizing the asymmetry in H+ flux, by increasing or decreasing it on both sides equally, both randomized the location of the viscera without causing any other defects. To understand the mechanism of action of H+-V-ATPase, researchers isolated its two physiological functions, cytoplasmic pH and membrane voltage g...

Leave it to salmon to leave no stone unturned

...nges in rivers and lakes far from the nests. From decreasing the amount of algae there is to eat to possibly influencing when aquatic insects emerge, spawning salmon can be extraordinary "environmental engineers," says Jonathan Moore, a UW graduate student in aquatic and fishery sciences. Ignoring this role c...

Scientist warns of threat to last stronghold of endangered turtle

...ca, the focus of this study. With fishing yields decreasing in European seas the EU has struck up a number of agreements with African nations to fish their waters. Amazingly, most EU fishing concessions don't even incorporate compulsory bycatch monitoring programmes. Scientists from the University of Exeter...

Cancers that quickly become resistant to therapy, such as melanoma and ovarian tumors, do so because they have found ways to prevent mitochondria from releasing ...
