Gionbelli, Marcelo G. Machado Background Beef cows herd accounts for 70% of the total energy used in the beef production system. However, there are still…
Supernovae, neutron star collisions and active galactic nuclei are among the most energetic phenomena in the known universe. These violent explosions produce high-energy gamma rays and cosmic rays, which can easily travel large distances—making it possible to see objects and events far outside our own galaxy.

A new facility should help advance understanding of black holes, supernovae and the origins of our universe. Today, the U.S. National Science Foundation (NSF), the U.S. Department of Energy and Mexico’s Consejo Nacional de Ciencia y Tecnología (CONACYT) inaugurated a new gamma ray astrophysics facility known as the High Altitude Read Full Article Here For…
By Melissa C. Lott Where does it comes from? Where does it go? These two questions were asked last summer here on Plugged In with respect to the energy use in the United States. Now, let’s take a look at energy… — Read more on ScientificAmerican.com Read Full Article Here For more great articles: Scientific…

By Alexandra Boltasseva Recent years have seen dramatic growth in the field of nanoscale optics. The advantages of nanophotonics—wide bandwidth, no cross-talk, high speed, and compactness—are key factors enabling optical technologies that have an impact on many areas of society, including information and communications, imaging and sensing, health care, energy, manufacturing, and national Read Full…
By Mary Mohrin Deterioration of adult stem cells accounts for much of aging-associated compromised tissue maintenance. How stem cells maintain metabolic homeostasis remains elusive. Here, we identified a regulatory branch of the mitochondrial unfolded protein response (UPRmt), which is mediated by the interplay of SIRT7 and NRF1 and is coupled to cellular energy Read Full…
