Return of the mammoth? Dolly scientist says beast should be cloned | Fox News - 0 views

  •  
    After the successful cloning of Dolly the sheep, scientists are hopeful to clone/bring back the mammoth from extinction. Notably well preserved blood in a recent finding of mammoth remains could lead to mammoth stem cells. With these stem cells and the use of elephant eggs to grow an embryo, a baby mammoth could be born. The stem cells could also form gametes, which, if from a female, could lead to both breeding and cloning mammoths. The method of cloning could be fairly similar to the process used to create Dolly the sheep. Although bringing back the mammoth would be beneficial for science, a debate exists arguing the issues.

Scientists grow teeth using stem cells from urine: study  - NY Daily News - 0 views

  •  
    Chinese researches have discovered an ability to transform the cells found in urine into stem cells. Driving these scientists was the remarkable ability that stem cells possess: the ability to transform into other cells. These scientists actually transformed the cells from urine into stem cells, and used those stem cells to create human teeth in mice jawbones. This experiment did suffer several flaws, however. These teeth-like structures did contain a number of components that real teeth are composed of: enamel, dentin, and pulp. Even so, these teeth were only one-third as hard as human teeth. Additionally, this experiment resulted in 70% of the mice absent of teeth-like structures. Despite the flaws through the experiment, this discovery comes close to the regrowth of human features and gives hope to a possible future of regenerated human teeth. Better methods of obtaining cells with the ability to become stem cells exist, further giving the world of science hope in human body repair and regrowth.

    A 50 year old man who previously went to a rock concert about a month before he started having very bad and persistent headaches. The doctors did lots of different tests and the patient never was a substance abuser and never experienced any head injuries, but did mention doing head banging at the concert. When they did a cranial Ct scan the man had received a blood clot. They doctors believed the blood clot was from the headbanging and they removed the blood clot and the patient was sent home with no more headaches.

Music: It's in your head, changing your brain - CNN.com - 0 views

  •  
    Music can have extraordinary affects on the human brain. Looking in on "ear worms" (meaning getting a song stuck in your head), research reveals that what's going on is neural circuits getting stuck in a repeating loop, playing the thing repeatedly in the head. It is also found that, in the process of human evolution, the structures that respond to music in the brain were first to evolve than the structures that respond to language. Further research also looked into the brain's response to musical pleasure, and animals' response to beats.

The stuff of dreams | Science News for Kids - 0 views

  •  
    Using a computer program, Neuroscientist Kamitani led an experiment to compare the brain's activity during sleep and during wake. This study involved 3 adult males, who were hooked up to a fMRI (used to measure brain activity). Being told to describe the things they saw in their dreams, the 3 adults were also asked to look at those objects in real life. Kamitani's study revealed that the brain responded similarly to objects dreamt about or seen awake.

    Proteus, a 0.14 inch tall motor using piezoelectricity  which puts electrical charge into motion. The whole idea of this motor is to send it into the brains blood to help treat the damaged tissue. The study plans on inserting the little motor into a robot with article blood and cells and see how it work and the reduce it to the size of 1/300 of a sprinkle.

Parents and Adult Children: Mutually Irritating | Popular Science - 0 views

  •  
    Parents and their children both aggravated each other at one time or another but it is said that at a younger age parent aggravate their children more when they are younger.

    When EBay first came out there tended to be a scare that there was a mass production of fake sells going on this site, but they found out that EBay helped find the people selling the fakes. In Peruvian, Mexican, Egyptian, Bulgarian and Chinese workshops they are creating fake antiques to go online and sells for the price of the real ones. Stanish, a researcher on this situation has discover over the past couple of years even he cannot figure out if the product are real or fake, about 5 percent of the product are real and 30 percent are obviously fake but the rest is inconclusive.

A Squirt of Stem Cell Gel Heals Brain Injuries | Popular Science - 0 views

  •  
    Dr. Zhang's has created a liquid gel to insert into damaged parts of the brain from traumatic brain injuries. There has been little success on humans, but testing has been done on rats and there has been very positive results. On humans there has also been other techniques such as inserting donor cells into the damaged area but the cells end up dying off. Human success in the experiment is estimated to take up to 3 years.
