Soybeans with resistance to soybean cyst nematodes seem to have a yield advantage compared to susceptible varieties when SCN is present. Until now, scientists did not know what level of SCN infestation is needed to achieve the yield advantage. A new study shows that SCN resistance from the soybean accession PI 88788 offers yield advantages even at very low infestation rates.
Astronomers have found an enormous, glowing blob of gas in the distant universe, with no obvious source of power for the light it is emitting. Called an ‘enormous Lyman-alpha nebula’ (ELAN), it is the brightest and among the largest of these rare objects, only a handful of which have been observed.
Sexual reproduction and viral infections both rely on a functionally identical protein, according to new research. The protein enables the fusion of two cells, such as a sperm cell and egg cell, or the fusion of a virus with a cell membrane. The discovery suggests that the protein evolved early in the history of life on Earth, and new details about the protein’s function could help fight parasitic diseases such as malaria.
Why are pancreatic tumors so resistant to treatment? One reason is that the ‘wound’-like tissue that surrounds the tumors, called stroma, is so dense, likely preventing cancer-killing drugs from reaching the tumor. A team has now discovered heterogeneity in the fibroblast portion of the stroma, opening up the possibility of targeted treatment.
