When the FBI first conceived of DNA Technical Leaders as a requirement for CODIS eligibility, it sought to ensure that forensic DNA operations were overseen by individuals with sufficient training, education, and experience. It also knew that many current supervisors of forensic biology units did not have sufficient credentials. The emergence of technical leaders in forensic DNA units across the United States created one of the most challenging and complex HR problems in the history of forensic science. Many unit supervisors who did not qualify as technical leaders no longer had full…

800x600 Bimaximal Pattern Links Color Quark and Neutrino Mixing-Angle Approximations                               By Emmanuel Lipmanov In the SM weak interaction phenomenology, the leading approximation benchmark mixing patterns of neutrinos and quarks are different – bimaximal pattern and zero one, respectively. In contrast, we consider here the bimaximal pattern as the only basic primary mixing link between leptons and quarks. The difference in…

Basic Connection Between Neutrino Flavor and Geometry: Absolute Masses and CP-Violation Model The true physics approach means that independent of how clever you are and what known expert you are and how beautiful your theory is, it should be rejected if disagrees with experimental data. The opposite is also true. Supported by data solid semi-empirical research (beyond mainstream) of less known author must have the preference of full attention. In Standard Model the electroweak interactions are weak and treated by perturbation approach. And so, the clearly supported by data…

Black holes are hot. Well, thermodynamically these suckers are freaking cold, but they do attract more attention than hot supernovae. And with attention comes recognition. As announced last month, as much as 97% of the $ 6.3 mln 2016 Breakthrough Prize money for physics went to black hole research. More recognition is to be expected. That is to say: it is hard to imagine this year's Nobel Prize for physics not going to those who created microphones sensitive enough to listen to black holes waltzing and whirling in galaxies far away. The recordings are in stereo and rather modest in signal-to…

Leptospirosis is a serious but neglected emerging disease that infects humans through contaminated water. It is a major public health problem in South East Asia and South America, with over 500,000 severe cases every year. Between 5% and 20% of these cases are fatal. Rats and other mammals carry the disease-causing pathogen Leptospira interrogans in their kidneys and when they urinate, they contaminate surface water with the bacteria, which can survive in the environment for long periods. Now research published in the May issue of the journal Microbiology shows for the first time how…

Our biological rhythm controls many metabolic functions and is based on the circadian rhythm, which is a roughly 24-hour cycle that is important in determining sleeping and feeding patterns, cell regeneration, and other biological processes in mammals. A newly discovered rhythm discovered by NYU dental professor Dr. Timothy Bromage also originates in the hypothalamus, a region of the brain that functions as the main control center for the autonomic nervous system. Unlike the circadian rhythm, this clock varies from one organism to another, operating on shorter time intervals for small mammals…

Preliminary results from DNA analysis of wolverine scat samples collected on the Tahoe National Forest do not match those of historic California wolverine populations, according to U.S. Forest Service scientists. Geneticists with the agency’s Rocky Mountain Research Station recently began analyzing samples, when wildlife biologists with the Tahoe National Forest and California Department of Fish and Game began sending hair and scat samples they collected from wolverine detection sites on the national forest to a lab in Missoula, Mont. The interagency effort began in March after an Oregon…

These are great In-flight Photos of the F/A-22 as the first Aircraft Delivery was being made to Langley AFB in Va. . Langley is to be first Operational AFB for the F/A-22. It is a very beautiful AFB, located in a picturesque location, as you can see in these photos, near Norfolk and Hampton , Va. The Aircraft flying along with the F/A-22 in the last of these photos is the F-15, which will be replaced by the F/A-22 which is several times better than the F-15. In Actual In-flight (simulated) Combat Operations against the F-15, two F/A-22's were able to operate without detection while it went…

NUREMBERG, Germany, February 22 /PRNewswire/ -- - Eco-Experts Call for Clear Climate Concepts for Organic Farming All consumers and experts would agree that, whenever a person eats organic products, they are also doing something for the environment. But does an organic apple from Argentina protect the climate more or better than a conventional apple from a nearby orchard? This seems to be an area, in which the organic sector still has some catching up to do, if one is to believe the experts that came together last Thursday to discuss issues affecting the organic sector. At the traditional "…

Dark Matter and Dark Energy The Science and Technology Facilities Council has provided information that Science Daily has posted as an abstract of an article by Dr. Hong Sheng Zhao titled "Dark Fluid: Dark Matter And Dark Energy May Be Two Faces Of Same Coin." You can read this abstract at the web site below: http://www.sciencedaily.com/releases/2008/01/080131094056.htm Dr Hong Sheng Zhao, of the University of St. Andrews, School of Physics and Astronomy, has shown that dark matter and its counterpart dark energy may be more closely related than was previously thought. "Both dark matter and…
