Scientists study the affects of nitrogen fertilizer applied to corn hybrids
Scientists at the USDA-ARS, Jamie Whitten, Delta States Research Center in Stoneville, MS, have found that Bt concentrations in young corn plants are directly influenced by the amount of nitrogen fertilizer applied at planting. The research is published in the January-February 2003 issue of Agronomy Journal.
Hybrid corn cultivars genetically modified to have the Bt-producing gene synthesize special proteins that can kill the larva of certain corn insect pests, such as fall armyworm and southwestern cornborer. The Bt corn hybrids provide farmers with an alternative to avoid costly damage from feeding by these pests without the use of pesticides.

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...
