Obesity raises risk of breast cancers

Obesity raises risk of breast cancers Women who gain weight as adults face a higher lifetime risk of all types of breast cancer. A study of about 44,000 women found that the more weight a women gained, the greater the risk for all different types of breast cancer. A recent study has shown that women who have gained twenty pounds or less during their life as an adult, women who gain more than sixty pounds are almost twice as likely to have ductal type breast tumors and women are more 1.5 times more likely to have lobular types of cancers. Breast cancer is the second leading cause of cancer death among U.S. women, after lung cancer, of course all those stupid smokers. Over 200,000 people have breast cancer and an additional 40,000 die from it each year. Read it for yourself. Here.

Tumor Killing Bacteria

Two scientist at UCB and UCSF are trying to kill cancer with bacteria. however it is not only toxic to cancerous tissue but healthy as well, but bacteria can target cells. in order to make a cancer-killing bacteria, they must create organisms that perform complicated functions in the bloodstream.
The bacteria will only produce the tumor-killing toxin when in the cancerous cell. In order to make a bacteria that can sense a tumor they took an oxygen sensor from E.coli and linked it to invasin, which causes the organism to invade cancer cells.
They are now trying to make this system more specific. to be sure the bacteria only invades cancer cells, they are creating a genetic mechanism which allows the invasin proteins to be expressed. for more information go to: http://www.technologyreview.com/read_article.aspx?id=16949&ch=biotech

Potential cloning

Cloning of human embryos is something that researchers at Harvard hoped to accomplish. This work is aimed to cure human blood diseases such as leukemia, sickle-cell anemia, and other blood related diseases. This research, however, is very controversial work.

There are, so far, three main researchers on this project. Dr. George Daley, Douglas Melton, and Kevin Eggan. They each are investigating deep into different aspects of Stem cell research through cloning of human embryos. Daley would not said he specifically was doing or give any other information. On the other hand, Melton is working on Diabetes while Eggan is working on Lou Georgia disease.

The whole purpose for human embryo cloning is to produce a transplant material that would be genetically matched to a patient. This would make sure that the cells would not be rejected. This theory, to many people, is ethnically wrong.

Pick Your Poison

Recently biologist have noticed that poison ivy has been growing larger then it had been growing last year, but also in the toxic substance that causes a rash to occure on people by 20%. So what is the reason for common poison ivy to mutate into this "hell ivy" it seems that the culperit is none other carbon dioxide, it would seem that it causes it to grow more efficiantly than ivy that receved regular air.

"Big deal" some people might say when in reality it is a big deal, for it appears that not only poison ivy is affected by this but also other vine type plants this can result in a longer alergy season and can also steal away the nutrients plants need to grow thus choking our oxygen production, also the animals that eat these plants get fewer nutrients from them since the carbon dioxide throws off the balance in the plants.

When I first read this artical I thought that this would also cause other types of plants to grow better also when in reality they do not because the vines not only steal more of the plants sun light with its leaves but also more of the plants nutrients. If you like more information click here.

Do Strict Parents Have Fat Kids?

Studies show that families with stricter rules have a greater percentage of overweight children than families with flexible rules. The studies show that 17% of children with strict parents are overweight, but only 3.9% of children are overweight in families with flexible parents. This may be because children with strict parents are more stressed and use food as a way to feel better.

This also is true with academics and depression. Children of flexible rule-setting parents do better in school and are not as depressed. The study was of mothers and how they treated their children when they were 4, and the children’s weight was later measured when they got into first grade.

When I first read the title I was shocked, I couldn’t understand how this could happen. But now, it seems very logical. The research doesn’t seem to have been very thoroughly done, because the majority of those surveyed were white mothers and the mother’s weight wasn’t considered either to see if that might be a factor in their children’s weight.

Global Warming and Hawaii : (

There is a chain of small islands in Hawaii that may become that biggest marine sanctuary in the United States by next year. Because of global warming, though, the rare wildlife; including rare species of seals, sea turtles, and birds; could disappear. A group of Hawaii-based scientists have come to the conclusion that by 2100 two-thirds of some Northwestern Hawaiian Islands (NWHI) could be underwater.

Jason Baker led the team of scientists and found the threats to the islands. His team found that during the 20th century sea levels rose about 6 inches and levels are expected to increase even further and quicker this century.

To figure out the possible effects of the sea level rising, Baker's team created 3-D computer images of the islands. They used scenarios forecast by Intergovernmental Panel on Climate Change (IPCC). If by 2100 the sea level rose just 18.9 inches, about 65 percent of the islands would be submerged. here

Let's All Have A Siesta!!!!!!!

Scientists at The University of Manchester have uncovered how brain cells that keep us alert become turned off after we eat. Dr. Denis Burdakov, the lead researcher based in Manchester’s Faculty of Life Sciences says, "We have pinpointed how glucose - the sugar in food - can stop brain cells from producing signals that keep us awake."

His research shows exactly how glucose blocks brain cells that make orexins, tiny proteins that are vital for normal regulation of our state of consciousness. According to Dr. Burdakov they have identified the pore of in the membrane of orexin-producing cells that is responsible for the inhibiting effect of glucose. This mechanism is so sensitive it can detect minute changes in glucose levels - the type that occurs between meals for example.

Dr. Burdakov also says, "This research perhaps sheds light on why our European friends are so fond of their siestas." Now we know that a siesta after a hearty lunch is natural.
