Chromosomal abnormalities play important role in autism

According to wikpiedia, Autism is a brain development disorder that impairs social interaction and communication, and causes restricted and repetitive behavior, all starting before a child is three years old. It is very heritable, although the genetics of autism are complex and it is generally unclear which genes are responsible. A study showed that previously unknown chromosomal abnormalities have a

Human Embryonic Stem Cell Lines Created Without The Destruction Of Embryos

The ethical and moral aspects of using stem cells have been discussed a lot and it seems there is no good answer; genetic practically has no limit and since the discovery of DNA things have evolved very quickly. But the thing is that the moral aspects concerning it could be left unsolved and yet everybody could be happy. How? Well

Generosity is probably somewhat genetic

We have just began to understand our genome yet there are still numerous things we fail to understand; there is a very big number of genes of which we know very little about. Just how much of what we do and think is influenced by our genes remains a mystery, but genetics research is going a long way to enabling

Flowering Plants Evolved Very Quickly Into Five Groups

So Charles Darwin called it the “abominable mystery” of early plant evolution. But the University of Florida and University of Texas at Austin scientists have shed light on what was and is a very intriguing thing. The scientists are reporting that the two largest groups of flowering plants are more closely related to each other than any of the other

Scientists Melt Million-year-old Ice In Search Of Ancient Microbes

Scientists from the University of Delaware and the University of California at Riverside have thawed ice estimated to be at least a million years old from above Lake Vostok (update – first samples taken from lake Vostok). This lake is hidden more than two miles beneath the frozen surface of Antarctica and has been This was published by the University

Domestic Cat Genome Sequenced

Not a long time ago scientists have sequenced chimpanzee, mouse, rat, dog, and cow DNA. This made it possible for them to understand numerous things including the hundreds of chromosomal rearrangements that have occurred among the different lineages of mammals since they diverged from a diminutive ancestor that roamed the earth among the dinosaurs some 100 million years ago.The cat

Biodegradable Nanoballs To Deliver Drugs Directly To Cancer Cells

Nanotech is a very young science. It reffers to a field of applied science and technology whose unifying theme is the control of matter on the atomic and molecular scale, normally 1 to 100 nanometers, and the fabrication of devices within that size range. A meter is 1 000 000 000 times bigger than a nanometer so it is easy

St. Bernard shows Evolution At Work

  This dog is famous in the world because it is very big but very gentle – also, thanks to a certain Beethoven movie. The ancestors of the St. Bernard are the herding dogs of Swiss farmers like the Greater Swiss Mountain Dog, as well as hunting dogs and watchdogs. Their history has also been connected with the hospice at

Understanding the Stem Cells

  There is a lot of interest around the problem of stem cells; a lot of practical discussions, and a lot of moral discussions as well. Whether it is good or it is not good to use them or whether it is religiously condemned is not going to be discussed here. This is meant to make you understand how stem

Genetically Engineered Poplar Plants Disarm Toxic Pollutants 100 Times Better Than Controls

  Scientists are working out different ways to improve air quality and clean up contaminated sites. In numerous cases the simplest, most natural solution is the most efficient. This could be the case here as they try to break certain kinds of pollutants into harmless byproducts, the key answer could be held by some plants. These plants are able to

System To Build Transplant Tissue Created

  Organ transplants are no longer a novelty, ┬ábut transplants could help save a lot of lives of people who need certain tissues to live. There is probably going to be a day when laboratories could be able to grow synthetically engineered tissues such as muscle or cartilage needed for transplants [later edit: Scientists create 3D tissue printer that prints

Thriving Hybrid Salamanders

  So a new study conducted by UC Davis research revealed interesting things from interbred salamanders, results that go against what was the dominant idea about interbread species. The salamander experts studied the survival rates and genetic makeup of three types of salamanders: native California tiger salamanders (Ambystoma californiense), which are protected under the U.S. Endangered Species Act; barred tiger

Surprise In The Organic Orchard — A Healthier Worm In The Apple

  Just like you can catch a cold from a virus so can other animals, as well as insects. But they can catch more than just a cold. Some viruses are dangerous for the pests but they are not of any danger to humans or other animals. The proverbial worm in the apple, the codling moth caterpillar, has been controlled

Getting to know your roots

The Genographic Project aims to map historical human migration patterns through collecting and analyzing DNA samples from many people all over the world. The project has already been around for almost two years, and perhaps its main attraction resides in that everybody can find out about their own personal lineage, if they purchase the genographic project public participation kit. After

What Is Genetic Engineering

  So according to Wikipedia, genetic engineering involves the isolation, manipulation and reintroduction of DNA into cells or model organisms, usually to express a protein to reach desired effects. The aim is to introduce new characteristics or attributes physiologically or physically, such as making a crop resistant to a herbicide, introducing a novel trait, enhancing existing ones, or producing a
