15 generations of untrained jocks, couch potatoes show big physiological adaptations
So, you don't like to exercise? Maybe you could blame it on your great-great-grandparents. Similarly, if you're a practiced and proud couch potato who suddenly woke up to the fact that you're a "natural" athlete, the credit could also belong to your genes. Exercise research traditionally has focused on the effects of training, rather than underlying genetic mechanisms. But physiologists wo...Fighting malaria by manipulating mosquitoes' sense of smell
Combating the spread of malaria by manipulating the mosquitoes' sense of smell is the object of an ambitious research project, led by Vanderbilt University, that has been selected to receive $8.5 million as part of the Grand Challenges to Global Health. The initiative, which was launched by the Bill and Melinda Gates Foundation, has just announced the selection of 43 "groundbreaking" resea...Mosquitoes are more attracted to individuals infected with malaria
Malaria remains a devastating problem in Africa and understanding the factors affecting its transmission remains a crucial part of the effort to combat the disease. A new study published in the premier open access journal PLoS Biology conducted in Western Kenya by Jacob Koella and colleagues now reveals that mosquitoes are more attracted to children with the infectious stages of malaria than to t...Gene that helps mosquitoes fight off malaria parasite identified
Researchers have identified a gene in mosquitoes that helps the insects to fight off infection by the Plasmodium parasite, which causes malaria in humans. Anopheles mosquitoes transmit the malaria parasite to nearly 550 million people worldwide each year with these cases resulting in more than 2 million deaths annually. The protective gene was identified in a study conducted by a team of investig...Finding rewrites the evolutionary history of the origin of potatoes
Humans have cultivated potatoes for millennia, but there has been great controversy about the ubiquitous vegetable's origins. This week, writing in the Proceedings of the National Academies of Sciences, a team led by a USDA potato taxonomist stationed at the University of Wisconsin-Madison has for the first time demonstrated a single origin in southern Peru for the cultivated potato. The s...Midgard Prec Current Source from Stoelting Co.
Description:The latest generation of the popular precision current source, designed at M.I.T. for the iontophoresis of neural transport tracers such as horseradish peroxidase (HRP) or tritiated amino acids into neural tissue, is now available from Stoelting. It may also be used to make small lesions, and in applications requiring precise current control through high impedance....Quixell Cell Transfer System from Stoelting Co.
Description:Quixell, manufactured by Stoelting, selects single cells, or clusters, with rapid, smooth, precise control. In no time at all, a single cell can be targeted, then click-click on the keypad...the cell is collected into the pipette, and automatically transferred to the individual wells of a microtiter plate. Quixells unique aspiration and expulsion system allows transfer of 1-5 cells at a time, int...Bush vetoes stem cell research bill

Diets rich in tomato products, such as tomato sauce and ketchup, have long been associated with a reduced risk of various cancers, especially prostate cancer, but the reason for such an action is yet to be found. Clinical trials have suggested that lycopene, which is found in tomato products and other natural plant nutrients may be effective in preventing prostate cancer and treating t...Raspberries Are Richer In Anti-Oxidants Than Tomatoes Or Broccoli
Raspberries are said to possess ten times more anti-oxidants than in any other products like tomatoes or broccoli, according to Dutch researchers.// According to foodconsumer.org, researchers from Plant Research International in Wageningen, the Netherlands, said flash freezing raspberries in liquid nitrogen and storing them at minus 20 degrees Celsius destroys much of the vitamin C, but...Tomatoes Might Inhibit the Development Of Prostate Cancer
A new study finds that lycopene is not the only compound in tomatoes that could prevent prostate cancer.Lycopene is a carotenoid in tomatoes that gives //them that familiar red color. Research has suggested lycopene could reduce the risk of prostate cancer. But it is unclear if lycopene itself is responsible for the risk reduction. Researchers from the University of Illinois studied th...Swanson Titanium Great Toe Implant
