New method used to detect antibiotics in honey
'The method we have developed means we can simultaneously detect various kinds of antibiotic residues (macrolides, tetracyclines, quinolones and sulfonamides) in honey,' Antonia Garrido, lead author of the study and...
Some Sharks, Barracuda Completely Gone in Caribbean
The big fish of the Caribbean reefs are disappearing due to unchecked overfishing, though programs to work with small-scale fishers are underway, experts say.
Researchers develop whole genome sequencing approach for mutation discovery
The Stowers Institute's Hawley Lab and Molecular Biology Facility have developed a 'whole-genome sequencing approach' to mapping mutations in fruit flies. The novel methodology promises to reduce the time and...
Gene may 'bypass' disease-linked mitochondrial defects, fly study suggests
By lending them a gene normally reserved for other classes of animals, researchers have shown they can rescue flies from their Parkinson's-like symptoms, including movement defects and excess free radicals...
Researchers find snippet of RNA that helps make individuals remarkably alike
'No two people are alike.' Yet when we consider the thousands of genes with frequent differences in genetic composition among different people, it is remarkable how much alike we are...
Scientists discover specific small RNA pathways protect germ line from transposons
Cells of higher organisms are in a constant struggle against some of their own DNA - repeated bits of DNA sequence called transposons that have infiltrated host genomes over the...
Extreme makeover: Stanford scientists explore new way to change cell's identity
Even cells aren't immune to peer pressure. Scientists at the Stanford University School of Medicine have now shown that skin cells can be coaxed to behave like muscle cells -...
Oestrogen controls how the brain processes sound
Scientists at the University of Rochester have discovered that the hormone oestrogen plays a pivotal role in how the brain processes sounds...
Illinois gathering up small rattlesnakes
CHICAGO, May 6 (UPI) -- Illinois wildlife officials are holding a rattlesnake roundup, this one aimed at saving the local population of eastern massasauga snakes.
Yeast Cells Are Set to Fly for Space Experiment
Previous experiments indicate that some organisms become hardier and more virulent in outer space and more resistant to drugs.
Ancestor Of HIV In Primates May Be Surprisingly Young
The ancestors of the simian immunodeficiency viruses (SIVs) that jumped from chimpanzees and monkeys, and ignited the HIV/AIDS pandemic in humans, have been dated to just a few centuries ago....
Preserving Eggs For Reproduction: Drugs Needed To Be Given In Stages To Improve Chances For Later Fertilization
Cryoprotectants needed to preserve eggs for reproduction need to be given in stages, albeit rapid ones, say scientists who have developed a mathematical model that predicts optimal time for loading...
Tiny Plant Virus May Be Useful As Drug Deliver Agent
We typically view viruses as scourges. But scientists are hoping to enlist the help of one particular virus to treat disease. Their discovery that the tiny plant virus, cowpea mosaic...
Snippet Of RNA Helps Make Individuals Remarkably Alike
Uniformity, or singleness of form, is a general property of life. Biologists have long pondered how this feature is produced in the face of such great variation in genetics and...
Tea for the treatment of type-2 diabetes
The researchers have harvested the ingredients for the tea in Africa, totalling approximately fifty kilos of leaves and three hundred kilos of fruit from the wild nature of Nigeria. Afterwards...
Experts: Mild swine flu could quickly turn deadly
(AP) -- A flu virus is a powerhouse of evolution, mutating at the maximum speed nature allows. A mild virus can morph into a killer and vice versa.
