Menstrual blood a good source of stem cells?

Researchers are always seeking more and more ways that are viable and safe for gathering stem cells. Now it seems they’ve finally identified a potentially unlimited, noncontroversial, easily collectable, and inexpensive source – menstrual blood. Stromal stem cells – cells that are present in connective tissues – have recently been identified in endometrial tissues of the uterus. What that means

‘Ruthlessness gene’ discovered

Recently, it seems there’s a gene for everything, from generosity to ruthlesness. That still doesn’t mean that you can blame everything on your genes, but it may go to show the fact that even some of the world’s most cruelest dictators may owe their behaviour partly to their genes, at least according to a study that claims to have found

Evolution slows down as number of competitors increases

According to a new research, published in PLoS, as the total number of different species in a certain group grows, the chance of the rate of new species apprearing decreases greatly. The research team believes these findings suggest that new species appear less and less as the number of species in a region approaches the maximum number that it can

Human skin cells ordered to be embryonic stem cells

As expected, genetics evolves everyday and finds more new and unexpected solutions to some of the most puzzling problems we have faced yet. Such a problem was the ethical side of using embrionic stem cells. But now, it seems it won’t be necessary to figure out whether it’s ethical or not, because we can bypass it. This is because UCLA

‘Holy Grail’ Of Nanoscience achieved ?!

Researchers at at the U.S. Department of Energy’s Brookhaven National Laboratory have achieved something that many people call the Holy Grail of Nanoscience; this in fact reffers to the fact that they have used for the first time DNA to guide the creation of three-dimensional, ordered, crystalline structures of nanoparticles (particles with dimensions measured in billionths of a meter). What

First Detailed Map Of Nuclear Pore Complex Made

Understanding the mechanisms which take place is something scientists are have been trying to figure out for ages; because of it’s small size, maping it and understanding some things seems almost impossible, but this is a very important step in solving some molecullar puzzles. This would in fact speed up significantly the process of discovering and understanding of cells. A

Switching genes off and on

Working with genes is something very delicate and dangerous at the same time. If scientists were able to, say, turn a gene off when it is not needed or harmful and then turn it on at a certain point then that would be a huge breakthrough, with a list of benefits that could go on for miles. It seems that

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,  but 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
