When cold and flu season comes around, we take steps like getting our flu shots and taking immune supplements to strengthen our bodies' defenses against pathogens. Plants face pathogenic threats, too. Plant pathogens can ...

When researchers at Lund University investigated how UM171, a molecule used to make blood stem cells multiply, works, they made an unexpected connection. The results provide new insights into how one of the most common malignant ...

Soybean is a critical element of the global food supply: Between its use for animal feed and human consumption, it accounts for roughly two-thirds of plant-based protein meal output worldwide. Canada is a global leader in ...

Just a few minutes of freezing and thawing can have a decisive impact on how ferrihydrite, the most reactive iron mineral in cold soils, permafrost and glaciers, transforms, according to researchers at Umeå University. As ...

Subterranean clover's ability to bury its seed supports pasture persistence but makes commercial seed harvesting difficult. The industry relies on aging Horwood-Bagshaw (HB) suction harvesters, which collect seed from fully ...

How has offspring dependence on parents evolved over the course of evolution? Researchers at the University of Bayreuth, in collaboration with Kyoto University, Japan, have investigated one possible mechanism by studying ...
