Ants, not evil spirits, create devil's gardens in the Amazon rainforest, study finds

...th as many as 3 million workers and 15,000 queens, adding that the presence of multiple queens "undoubtedly contributes to colony longevity." Niche construction "The cultivation of devil's gardens by ants is an excellent example of niche construction," Frederickson says. "By killing plants of other spec...

Research suggests fitness of Florida panthers improved by limited breeding with Texas animals

...species is rare, and its range is restricted, just adding individuals from the outside is not going to work. Some thought it would be a waste of time, a waste of money." Pimm was himself skeptical about the success of such a rescue attempt in his 1991 book, "The Balance of Nature? Ecological issues in the ...

Lands surface change on Alaska tundra creating longer, warmer summers in Arctic

...zen for thousands of years is exposed, potentially adding more carbon dioxide to the atmosphere. The result is a positive feedback loop that could continue to raise temperatures in the region and further lengthen the snow-free period each year. Since the early 1960s, scientists have identified "hotspots...

Nanowires can detect molecular signs of cancer, scientists find

...cules with near-perfect selectivity," Lieber says, adding that the risk of false readings is minimized by the incorporation of various control nanowires. The scientists also fitted some nanowires in the arrays with nucleic acid receptors for telomerase, an enzyme inactive in most of the body's somatic cell...

Seaweed could make junk food healthier

Junk food could be made healthier by adding an extract of an exotic type of seaweed, say British scientists. The highly-fibrous seaweed extract, alginate, could be used to increase the fibre content of cakes, burgers and other types of food which usually contain large amounts of fat and a lo...

Gene discovery sheds light on causes of rare disease, cancer

...when InlB interacts with Met, the cell responds by adding a chemical tag to Met that flags it for protein recycling or degradation. Since Met is on the outside surface of the cell and the recycling and degradation machineries are inside, the cell must bring Met inside through endocytosis in order to dispose...

Study casts doubt on 'Snowball Earth' theory

...g the one anomalous spot would be quite unlikely," adding that the drill core came from an extensive formation of rocks with similar characteristics. "At what point does an enormous refugium become open ocean?" she asked. Skeptics also may argue that the rocks do not necessarily date to a glacial era, Olc...

Bacteria are key to 'green' plastics, drugs

...ated a second pathway and stimulated production by adding genes from lactococcus bacteria and sorghum. Each genetic pathway metabolizes glucose and produces succinate via dissimilar chemical reactions. That means the two don't compete or interfere with one another. In fact, Bennett and San designed the pat...
