chips. Although the mechanism by which acrylamide exerts its carcinogenic effect is unclear, acrylamide and its primary metabolite glycidamide are mutagenic. A new study reports a possible mechanism by which acrylamide mutates DNA and causes cancers....
Mice with hyperactive Wnt10b gene eat all they want, but have half the body fat of normal mice
...animals with too little fat. But don't stock up on potato
chips and ice cream just yet. The genetically altered mice are leaner than normal mice, but they also have some less-than-desirable characteristics such as underdeveloped mammary glands, an inability to generate body heat and skin that's twice as th...

tubers and the dormancy of buds in trees. The first breakthrough in explaining the mechanism of photoperiodism was proposed in the 1930s by Erwin Bnning (1906 - 1990), who worked in Jena, Koenigsberg, and since 1946 Tuebingen. Many aspects of plant ...
Tips from the Journals of the American Society for Microbiology

Potato-related plant species exhaust potato cyst nematode
Dutch plant ecologists have investigated how the potato
cyst nematode can be controlled using Solanum sisymbriifolium, a member of the potato
family. The plant produces a hatching agent which causes the nematode's eggs to hatch. However, the ...
Researchers developing 'sentinel plants' to warn of bioterrorism
