New Technology For Purifying Exhaust Gas From Diesel Engines
An increasing proportion of the Danish vehicle fleet consists of diesel vehicles. In urban areas diesel vehicles are causing air pollution (from carbon particles, nitrogen oxides (NOX)) and unburned hydrocarbons). As the European legislation tightens the rules for emissions, it will become more difficult and expensive to meet the requirements for particulate filters and DeNOx [...]
Rot’s Unique Wood Degrading Machinery To Be Harnessed For Better Biofuels Production
An international team led by scientists from the U.S. Department of Energy (DOE) Joint Genome Institute (JGI) and the U.S. Department of Agriculture Forest Service, Forest Products Laboratory (FPL) have translated the genetic code that explains the complex biochemical machinery making brown-rot fungi uniquely destructive to wood. The same processes that provide easier access to [...]

You have learned about Mitosis—-Now we are about to study Meiosis–Mitosis deals with the division of body cells and meiosis is the division of gametes. Compare and contrast the two. Have a great weekend!!!!!!!!!Mrs. D.

It is well believed that recessive traits are rare, but dominant or recessive traits may be more common in a population. For example, blonde hair is a recessive trait, yet blonde hair is common in parts of Scandinavia. Conversely, dominant traits are not always the most common. For example, having 6 fingers on one hand [...]

Although mendel was brilliant, he had difficulty learning from scientific texts. In the monastery gardens, Mendel explored the scientific ideas he had trouble with in school. While trying to grow better peas, he discovered genetics, an entirely new field of science. What do you think would help you be more successful in science?

You have probably noticed that different people have different traits, such as eye color, hair color, and ear lobes that don’t directly attach to their head. Where do people get these different traits?
New Catalyst Paves The Path For Ethanol-powered Fuel Cells
A team of scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, in collaboration with researchers from the University of Delaware and Yeshiva University, has developed a new catalyst that could make ethanol-powered fuel cells feasible. The highly efficient catalyst performs two crucial, and previously unreachable steps needed to oxidize ethanol and produce [...]
Single Gene Lets Bacteria Jump From Host To Host
All life — plants, animals, people — depends on peaceful coexistence with a swarm of microbial life that performs vital services from helping to convert food to energy to protection from disease.
Now, with the help of a squid that uses a luminescent bacterium to create a predator-fooling light organ and a fish that uses a [...]
