Green light: a signal to slow down or stop.
Light has a profound effect on plant growth and development. Red and blue light best drive photosynthetic metabolism, so it is no surprise that these light qualities are particularly efficient in advancing the developmental characteristics associated with autotrophic growth habits. Photosynthetically inefficient light qualities also impart important environmental information to a developing pla...
متن کاملA green light for new research.
water on culture medium, let it incubate, and see if any bacterial colonies develop. But that technique demands lots of waiting, and you might prefer a quicker technique-say, one that allows you to watch the bacteria grow in real time. Laura Leff of the department of biological sciences at Kent State University in Ohio does just that-watches bacteria grow right before her eyes-by labeling them ...
متن کاملA Light Stop and Electroweak Baryogenesis
The possibility of creating baryon asymmetry at the electroweak phase transition in the minimal supersymmetric standard model is considered for the case when right-handed squarks are much lighter than left-handed ones. It is shown that the usual requirement v(T c)=T c > 1 for baryogenesis can be satissed in a range of the parameters of the model, consistent with present experimental bounds.
متن کاملGreen light for selected baby
Zain Hashmi is a three-year-old little boy from northern England with big brown eyes and a fatal disease, beta thalassaemia major. As his bone marrow is unable to produce sufficient numbers of red blood cells, he needs regular transfusions and is unlikely to survive for long unless transplanted with suitable stem cells. These could come from the bone marrow of a donor with matching tissue type,...
متن کاملGreen light for gene targeting in plants.
P recision engineering of eukaryotic organisms requires efficient techniques for homology-based replacement of an endogenous gene by an introduced gene, a process termed gene targeting (GT). Because foreign DNA is preferentially integrated by nonhomologous recombination in plants and animals, special strategies are needed to increase the frequency and facilitate the detection of GT. Developing ...
