Scientists have confirmed the feasibility of using a new drug delivery system "” the basis for a battery-powered skin patch "” to administer medication that shows promise for treating peripheral artery disease (PAD) and healing stubborn skin ulcers and burns. The needle-free delivery of the medication, which cannot be given by mouth and can have side effects when injected, is reported in the ACS journal, Molecular Pharmaceutics. Yogeshvar Kalia and colleagues explain that the...

By Abby Vogel Robinson, Georgia Institute of Technology Researchers have developed a microfluidic device that automatically orients hundreds of fruit fly and other embryos to prepare them for research. The device could facilitate the study of such issues as how organisms develop their complex structures from single cells -- one of the most fascinating aspects of biology. Scientists know that among an embryo's first major developments is the establishment of its dorsoventral axis, which runs...

Using fruit flies as a model to study embryo formation, scientists report in Nature Cell Biology that molecular breakdown of a protein called Bicoid is vital to normal head-to-tail patterning of the insect's offspring. Published online by the journal Dec. 19, the study shows how Bicoid is targeted for molecular degradation by a newly identified protein the researchers named Fates-shifted (Fsd). Without the interaction between Bicoid and Fsd, fruit fly embryos are improperly formed and...

REYKJAVIK, Iceland, December 15, 2010 /PRNewswire/ -- Scientists in Iceland have developed a revolutionary skincare product after more than a decade of extensive research in plant biotechnology. The skin-rejuvenating phenomenon is called BIOEFFECT(TM) EGF Serum. Made by Sif Cosmetics, it is the world's first skincare product to contain cellular activators made in plants. Six months after its launch in Iceland, the serum is already being used by over 20% of Icelandic women. BIOEFFECT...

The vivid colors and designs animals use to interact with their environments have awed and inspired since before people learned to draw on the cave wall. But how different creatures in the animal kingdom "” from colorful birds and reef fish to butterflies and snakes "” make and deploy their artful designs is one of nature's deepest secrets. Now, however, a team of researchers from the Howard Hughes Medical Institute at the University of Wisconsin-Madison has exposed the fine...

Sonic hedgehog, a gene that plays a crucial rule in the positioning and growth of limbs, fingers and toes, has been confirmed in an unexpected place in the embryos of developing mice "” the layer of cells that creates the skin. Named for a video game character, Sonic hedgehog describes both a gene and the protein it produces in the body. Its study is important to increase understanding of human birth defects. It was thought to be exclusively present in the cell layer that builds bone...

Researchers at the California Institute of Technology (Caltech) have proposed a novel model that differs from a widely held hypothesis about the mechanisms by which developing animals pattern their tissues and structures. Cells in a developing animal require information about their position with respect to other cells so that they can adopt specific patterns of gene expression and function correctly. The most accepted paradigm is that this positional information comes in the form of chemical...

Rats given a cancer-fighting drug spontaneously consume less alcohol, U.S. researchers say. However, the rat's taste for another rewarding beverage -- sugar water -- is unaffected. The researchers say erlotinib -- a drug used to treat non-small cell lung cancer -- makes fruit flies and rats more sensitive to alcohol. This is a very powerful example of how simple model organisms -- and the little fruit fly in particular -- can be used to move quickly from an unknown gene to a potential...

A researcher of the University of Innsbruck elucidates an important developmental mechanism It is the concentration of a few signaling molecules that determines the fate of individual cells during the early development of organisms. In the renowned journal Current Biology, a team of molecular biologists led by Pia Aanstad of the University of Innsbruck reports that a variety of molecular mechanisms accounts for the interpretation of the concentration of the signaling molecule Hedgehog. The...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
