When mice choose mates, experience counts
Choosing a mate is a big decision. And, at least for mice, it's one that is best made with input from one's peers. In a series of experiments designed help scientists understand the brain chemicals that guide mate selection, Pfaff and his colleagues exposed female mice to odors of either a male mouse alone or a male mouse with a female. The females consistently preferred the scent of males...Female pronghorns choose mate based on substance as well as show
When a female animal compares males to choose a mate, she can't order a laboratory genetic screen for each suitor. Instead, she has to rely on external cues that may indicate genetic quality. Until now, biologists have focused on elaborate ornaments, such as the peacock's tail, as cues that females might use. The thorny problem has been to explain how the correlation between male genetic q...T for two: Scientists show how immune system chooses best way to fight infection
A new study has suggested a novel way of combating diseases related to the immune system, including cancer and autoimmune diseases such as type I diabetes and arthritis. The study, funded by the Wellcome Trust, appears online in the journal Nature. T cells are produced by the body to fight infection. Scientists previously identified two types of T cell, both produced in the thymus: "effect...Many couples choose to donate surplus embryos for stem cell research
Nearly 50% of couples who were interviewed at least 3 years after undergoing in vitro fertilization (IVF) chose to donate their surplus, stored embryos for stem cell research, according to a report by the Spanish Stem Cell Bank in an April 26, 2007, advanced online publication of Cell Stem Cell, a new publication of Cell Press in affiliation with the International Society for Stem Cell Research....Genes and biomarkers that allow doctors to choose the right therapy for the right patient
Genetic and epigenetic variations ensure that no two people are exactly alike, and the same holds true for any two cancers. Now, researchers have the tools and the knowledge to help predict how individuals will respond to cancer therapies, enabling them to create more effective therapies for individual cancers ?personalized medicine.

The explosion of specific markets suchas genome projects and drug discovery has further increased the use ofthe microplate. Because mic...Choose the Right Transfection Agent for Your RNAi Experiment
The success of any RNA interference experiment depends on the efficient delivery of siRNA or siRNA expression vehicles (plasmids, PCR fragments) into cells. Many researchers use cationic liposomal and polyamine based reagents to deliver these molecules into cultured mammalian c...Top Retailers Choose RedPrairie

Hypertensive or blood pressure medication should always ensure the best outcome for the patient. This should be taken care by the doctors in order to avoid the side effects relating to these drugs. Several different drugs lower blood pressure effectively.// According to researchers at Texas University it is necessary to find out which to prescribe.Recent trials show that there are striking differ...Choose the apple wisely to keep the doctor away
If you think that consuming any type of apple to keep the doctor away will work, then// do a rethink as a study confirms that not all apples have the same health benefits. The study reveals that Red Delicious, Northern Spy and Ida Red are more beneficial as they have greater antioxidant activity than others. Agriculture and Agri-Food Canada in Guelph, Ontario undertook the study. It wa...Worms Learn To Choose Their Diet
A study done by a researcher Yun Zhang at the Rockefeller University revealed that good taste is not an inherent trait of worms. // The research was mainly conducted on C.elagans which is a very simple nematode. It lives in the soil and feeds on various bacteria (both harmless and pathogenic ones).It has 302 neurons totally which can be mapped to individual behaviors. The genes...Choose Foods That Keep Bad Cholesterol at Bay
Diet plays a major role in reducing the bad cholesterol. For example food like oat bran is known to lower bad cholesterol//. Canadian researchers said that by combining these food substances one can get the maximum benefit. People should go in for such diet as they are at a higher risk of getting a heart attack or a stroke. These diets reduce the bad cholesterol (LDL) as effectively as a commonly...
