No Clear Connection Between Mobile Phone Use And Brain Cancer, Interna
According to a study conducted in five Northern European countries, there is no clear connection between mobile phone use and malignant brain tumours. The results of the study were published in the web version of the International Journal of Cancer on 19th January.

Molecule Walks Like A Human -- Potential Applications In Molecular Com
A research team, led by UC Riverside's Ludwig Bartels, is the first to design a molecule that can move in a straight line on a flat surface. It achieves this by closely mimicking human walking. The "nano-walker"offers a new approach for storing large amounts of information on a tiny chip and demonstrates that concepts from the world we live in can be duplicated at the nanometer scale -- the scale of atoms and molecules.

U-M Scientists Find Genes That Control Growth Of Common Skin Cancer
Scientists at the University of Michigan's Comprehensive Cancer Center and the National Cancer Institute have identified genes that promote the growth and recurrence of skin cancer.

Discovery Could Help In The Development Of Sensors Against Chemical Th
Single-walled carbon nanotubes (SWNTs), which could play an important role in developing sensors against chemical threats, have enhanced interaction with ammonia because of the presence of oxygen groups on the nanotubes, researchers at Temple University have discovered.

I’m not sure whether I should admit the following, but this morning I found little scatterings of murine faeces and could detect a musky yet ammoniacal odour in the storage area where we keep our dog and cat food. Not nice. In case you haven’t guessed, we got mice.Odd that these little critters should be [...]

Advance In 'Nano-Agriculture:' Tiny Stuff Has Huge Effect On Plant Gro
With potential adverse health and environmental effects often in the news about nanotechnology, scientists are reporting that carbon nanotubes could have beneficial effects in agriculture. Their study found that tomato seeds exposed to CNTs germinated faster and grew into larger, heavier seedlings than other seeds. That growth-enhancing effect could be a boon for biomass production for plant-based biofuels and other agricultural products, they suggest.

Common herbicides and fibrates block nutrient-sensing receptor found i
Certain common herbicides and lipid-lowering fibrate drugs act in humans to block T1R3, a nutrient-sensing taste receptor also present in intestine and pancreas. These compounds were not previously known to act on the receptor, which influences glucose homeostasis and energy metabolism. The effect is specific to humans and not revealed during animal testing.

Researchers Gather Data In Tsunamis' Wake
Researchers from the University of Delaware's Disaster Research Center (DRC) have returned from South Asia after a social science reconnaissance mission mounted in the wake of the devastating tsunamis that struck in December.
