Mad Cow Breakthrough? Genetically Modified Cattle Are Prion Free
The U.S. Department of Agriculture's Agricultural Research Service have announced initial results of a research project involving prion-free cattle. ARS scientists evaluated cattle that have been genetically modified so they do not produce prions, and determined that there were no observable adverse effects on the animals' health. Stomach Ache? It May Be Newly Recognized Inflammatory Reaction
As many as one in four people in westernized countries experience pain or discomfort in their upper abdomen, and physicians have almost nothing to offer except antacid medicines, which usually don't work. Now, in a small but novel study, researchers have found evidence that an abnormal amount of inflammatory cells populates the upper intestine of affected individuals, which suggests a fresh way of understanding the common complaint. MicroRNA Helps Prevent Tumors
Researchers have found that when a single mircoRNA molecule is unable to regulate a specific cancer-related gene, tumors result. Engineering Lab Helping Ensure Safety Of Minibuses
Minibuses are a fairly common sight on the roads of many American communities. Public transit and social service agencies, among others, often use the 16- to 20-seat vehicles in order to provide access to public transportation to people with disabilities, as required by the Americans with Disabilities Act of 1990. It may come as something of a surprise, then, that minibuses buses in the United States are exempt from Federal Motor Vehicle Safety Standards, the rules developed to ensure occupants'safety during vehicular accidents and to minimize the severity of their injuries. Great Plains'Historical Stability Vulnerable To Future Changes
A survey of long-term trends in population, farm income and crop production in the agricultural Great Plains finds that technological advances, such as improved crop varieties, irrigation and fertilizer use, have greatly increased production of major crops and allowed rural populations to remain stable over the past 50 years even as metropolitan populations have soared. Yet substantial environmental impacts have resulted, including loss of soil carbon and high nitrate runoff, especially in irrigated areas. Lighter Higgs Particle? Physicists Make New Precise Measurement Of Mas
Scientists at Fermilab announced the world's most precise measurement by a single experiment of the mass of the W-boson, the carrier of the weak nuclear force and a key parameter of the Standard Model of particles and forces. The new W-mass value leads to an estimate for the mass of the yet-undiscovered Higgs boson that is lighter than previously predicted, in principle making observation of this elusive particle more likely by experiments at the Tevatron particle collider at Fermilab. Document of the Pontifical Council for the Pastoral Care of Migrants a
This June 2007 document features at paragraph 61 a "Drivers' 'Ten Commandments'"that is designed to promote courteous and safe behavior while on the road. Includes background about how the commandments were developed, such as on the moral aspects of driving and Christian virtues related to driving. Also includes material about "street women"(prostitutes), street children, and homeless people. Available in several languages. From the Vatican. Study Finds Connection Between Sound And Meaning In Words
A new Cornell study describes a series of linguistic experiments showing that the sounds (phonology) of a word can indicate whether it is a noun or a verb. An article on the subject will appear in the Proceedings of the National Academy of Sciences. Off-label Use Often Not Evidence-Based: Physicians Lack Knowledge Of O
In a recent national survey, a substantial minority of physicians erroneously believed that certain off-label uses of prescription drugs were FDA approved. This mistaken belief encourages them to prescribe these drugs, despite the lack of scientific evidence supporting such use. Overall, physicians were able to correctly identify the FDA-approval status of just over half of the 22 drug-indication pairs (i.e., a particular drug prescribed for a particular condition) included in the survey. [Ironic] An Italian pensioner committed suicide after his wife fell in
