Nuclear explosions and radioactive atoms generate these rays. Gamma rays can kill living cells, and medical professionals sometimes use them to destroy cancerous cells. In deep space, gamma ray bursts occur daily, but their origins are still a mystery. Read on to find out the difference ...
Nuclear SymmetricityA nuclear structure model of "ring plus extra nucleon" is proposed. For nuclei larger than He, protons (P) and neutrons (N) are basically bound alternatively to form a P + N ring. The ring folds with a "bond angle" of 90掳 for every 3 continuous nucleons to make...
Nuclear materials get used in everything from PET scans to chemotherapy. JohnnyGreig / Getty Images In hospitals or on TV, you've probably seen patients undergoing radiation therapy for cancer, and doctors ordering PET scans to diagnose patients. These are part of the medical specialty cal...
Cellular IRESs tend to integrate or interact with RNA chaperones, upstream open reading frames and/or G-quadruplex structures for function. The initiation factor eIF3 can have a specialized function in translation by directly binding to structured or chemically modified 5′ UTRs in target mRNAs to ...
The UK is responsible for energy security overall, key aspects of that security such as the production and regulation of nuclear energy and the regulation of electricity supply, and access to the minerals (coal, oil, gas) to produce energy. In that context, the devolved (and local government...
Although the FKBPs directly contact GR, they do not appear to isomerize GR prolines or engage GRNLS1 (nuclear localization signal 1) (GR467–505) (ref. 60) to regulate GR activity, as previously hypothesized8,61,62,63. While FKBP51 binds GR:Hsp90 similarly to FKBP52, we find that,...
In nuclear power plants, the chain reactions are very carefully controlled so they proceed at a relatively slow rate, just enough to sustain themselves, releasing energy very steadily over a period of many years or decades. There is no runaway, uncontrolled chain reaction in a nuclear power ...

They've evolved to thrive on all sorts of things, from oil spills and nuclear byproducts to human waste and decaying matter. But bacteria's penchant for a particular food source can benefit society. For instance, art experts in Italy turned to bacteria to chow down on excess layers of ...
