Prions picked up by tuning fork detector

Prions (or proteinaceous infectious particle; on comes from analogy to virion) are the nasty little buggers responsable for disorders such as mad cow disease and other neurodegenerative diseases. They’re dangerous especially as they’re really hard to detect before symptoms appear.Now, according to Nature, scientists are trying to develop sensors that can detect prions by having them bind to a tiny

Frog Could Offer Diabetes Treatment Hope

About 2.3 million diagnosed with diabetes just in the UK, and it’s estimated that some 750.000 people have it but don’t know yet. Most of them have diabetes type 2, which is caused mostly by obesity and usually develops in middle age. Type 1, or insulin-dependent diabetes, is a less common autoimmune disease that results in the complete destruction of

3D Virus Image Taken At Highest Resolution Ever

Viruses are sub-microscopic infectious agents that need other cells in order to reproduce. In fact, some scientists claim that viruses are not living beings, as they do not meet the criteria of the definition of life, because they don’t have cells; but they do have genes and evolve by natural selection. Still, they can be very harmful to us, so

Researchers ID Promising New Cancer Drug

Researchers have long searched for a novel cancer drug that activates a certain protein to kill tumor cells. But finding a drug that kills the cancer without causing damage to normal cells has been trully a challenging task. But now, things seem to be better and better; progress is being made every single day. Now, researchers at the University of

Clothes that monitor heart beat and other vital signs

The science of clothing has evolved greatly: we have light skiing suits that keep us warm at -20 (and more) Celsius degrees, we have clothes that allow transpiration from the inside to get out but don’t allow water from the outside to come in, and also a whole lot of other inventions which aid our lives, more or less.So it

Novel Anticancer drug from the sea identified

Everyday you hear about something that cures (or almost cures) cancer; some stand out and are quite effective, some are not. This drug appears to be in the first category, as it is highly potent compound with a unique structure, and scientists are thrilled to have found it. It was discovered by a collaborative team of researchers led by Dennis

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

Things are moving towards alternatives to animal testing

Traditionally, drugs, cures, chemicals and medical devices are tested on animals to give some insight on how these would react on humans, but more and more people are trying to find an alternative to this, including scientists involved in ICCVAM. So they have made a plan to further reduce, refine and replace the use of animals in research and regulatory

‘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

Big Pharma Spends More On Advertising Than Research

A drug company is a commercial business whose focus is to research, develop, market and/or distribute drugs, most commonly in the context of healthcare; from wikipedia. But according to a study by two York University researchers estimates the U.S. pharmaceutical industry spends almost twice as much on promotion as it does on research and development, contrary to the industry’s claim.

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

Brain Matures A Few Years Late In ADHD, But Follows Normal Pattern

Attention-Deficit Hyperactivity Disorder (ADHD), or Hyperkinetic Disorder affects about 5% of the world’s population. It is hard to cure it and in it is currently considered to be a persistent and chronic condition and medicine does not have any cure. This is because we fail to understand it as numerous studies have showed contrary results. What we do know are

The 10% of the brain myth

The media seems to be repeating the idea that we use just 10% of our brains and taking it as a given. Scientists have tried for years to change this misconception and they have clearly stated that there is no scientific evidence to suggest that we use only 10% of our brains. In fact it is very hard to say

Red Wine, Fruits And Vegetables May Stop Cancer

But it has to be the good quantity. Eating fruits and vegetables and drinking red wine could just be what gives the edge against cancer or what play a beneficial role for those with diseased hearts and circulatory systems. The cure could be at the grocery.The research conducted was published in the November 2007 issue of The FASEB Journal. What
