New horizons in the creation of synthetic enzymes

Mankind triumphed in a recent "competition" against nature when scientists succeeded in creating a new type of enzyme for a reaction for which no naturally occurring enzyme has evolved.

Luna discovers nanomedicine prototype aids in the growth of new hair follicles

Scientists at Luna's nanoWorks Division in Danville, VA, have been developing a portfolio of new candidates based on antioxidant nanomaterials which could lead to a platform technology for treating a wide range of diseases. “One of our new nanomedicine prototypes, after only two weeks of treatment, was found to increase the number of hair follicles fourfold in mice which are born genetically hairless,” said Robert Lenk, President of Luna's nanoWorks Division.

Deadly genetic disease prevented before birth in zebrafish with genetic patch

By injecting a customized "genetic patch" into early stage fish embryos, researchers at Washington University School of Medicine in St. Louis were able to correct a genetic mutation so the embryos developed normally.

Natural biomedicines from the ocean

With the number of terrestrial sources that yield novel treatments for human disease decreasing year by year, the oceans have been tapped as a promising resource for discovering new natural biomedicines.

New method to determine the “selective signature” of a gene

Scientists at MIT have come up with a mathematical approach for analyzing a protein simultaneously in a set of ecologically distinct species to identify occurrences of natural selection in an organism's evolution.

Silencing gene in tobacco plants reduces harmful carcinogens

In large-scale field trials, scientists from North Carolina State University have shown that silencing a specific gene in burley tobacco plants significantly reduces harmful carcinogens in cured tobacco leaves.

Scientists have revealed what may well be the first pervasive 'rule' of evolution

In a study published in the Proceedings of the National Academy of Sciences researchers have found evidence which suggests that evolution drives animals to become increasingly more complex.

Bird brains suggest how vocal learning evolved

Though they perch far apart on the avian family tree, birds with the ability to learn songs use similar brain structures to sing their tunes.

Small-bodied humans from island of Palau

Since the reporting of the so-called "hobbit" fossil from the island of Flores in Indonesia, debate has raged as to whether these remains are of modern humans (Homo sapiens), reduced, for some reason, in stature, or whether they represent a new species, Homo floresiensis.

MIT develop inexpensive cell-sorting method

Capitalizing on a cell's ability to roll along a surface, MIT researchers have developed a simple, inexpensive system to sort different kinds of cells - a process that could result in low-cost tools to test for diseases such as cancer, even in remote locations.

New insights into what happens on a molecular level during photosynthesis

In a technical advance that could allow researchers to watch cells as they act during the process of photosynthesis, scientists have developed a method that extends the power of fluorescence-mediated bio-imaging to see discrete pigments inside live cells of bacteria.

Biologists discover parochial bacterial viruses

Biologists examining ecosystems similar to those that existed on Earth more than 3 billion years ago have made a surprising discovery: Viruses that infect bacteria are sometimes parochial and unrelated to their counterparts in other regions of the globe.
