Genetic basis for multi-tasking?
Genetic basis for multi-tasking?
Psychologists have found that 2.5 percent of the American population has a special multi-tasking ability that allows them to do such things as safely drive and talk on the phone at the same time. The neural basis behind this effect is not known, but there are still some interesting questions that emerge. Should proven supertaskers be exempt from laws banning phone use while driving?

A miracle salve or another stem cell fraud?
This article talks about stem cell-derived ingredients being put into makeup and skin products and being sold on the market in Korea.

Some of the ingredients include stem cell culture fluids. This not only sounds nasty, it has the potential to spread HIV or hepatitis viruses.

I believe the use of stem-cell culture fluids has many negative bioethical implication

Looking to create life?
Two of the world’s premier geneticists, Craig Venter and Hamilton Smith have proposed a new approach to genetics. They are looking to create a simple microbe by mix and matching gene segments from previously known bugs and “drop them” into another bug and see if the new genetic makeup will bring the microbe to life.

heyy! I am doing a science lab report and my problem is this:
1.   Are corn seeds of type I (no treatment) and type II (heat treatment) viable?
2.   Does the heat exposure affect corn seed viability?

is this hypothesis a good one?
If the seed was accidentally boiled then the seed won’t grow because the heat will kill the seed.

Researchers have found an antigen, AnAPN1 that triggers humans to create antibodies that prevent transmission of malaria by mosquitoes. If a mosquito takes in enough of these anitbodies the disease can be 'locked' into it and become untransmissable. Though this is promising, the problem lies in getting it into the mosquitoes.

My thought was that the higher, the more damage. Although, I am not sure if I am correct. Can someone please explain? It will help me alot in my report.
