In the 150 years since the publication of Charles Darwin's 'Origin of Species',  despite consistent patterns of biodiversity identified over space, time, organism type and geographical region, there still remain two views of the process of 'speciation', the evolutionary process by which new biological species arise.

The first requires a physical barrier;  a glacier, mountain or body of water that separates organisms,  enabling groups to diverge until they become separate species. In the second scenario, an environment favors specific characteristics within a species, which encourages divergence as members fill different roles in an ecosystem. 

A lunar geochemist at Washington University in St. Louis says that there are still many answers to be found in moon rocks brought back by the Apollo 11 astronauts nearly 40 years ago.   And he's been studying them since then, so he should know.

Randy L. Korotev, Ph.D., a research professor in the Department of Earth and Planetary Sciences in Arts&Sciences, has studied lunar samples and their chemical compositions since he was an undergraduate at the University of Wisconsin and "was in the right place at the right time" in 1969 to be a part of a team to study some of the first lunar samples.

Synthetic Genomics Inc. (SGI), a privately held company co-founded by Craig Ventner in the business of applying genomic-driven commercial solutions to challenges like energy and the environment, announced a multi-year research and development agreement with ExxonMobil Research and Engineering Company (EMRE) to develop next generation biofuels using photosynthetic algae. 

SGI will receive milestone payments for achievements in developing biofuel products. Total funding for SGI in research and development activities and milestone payments could amount to more than US$300 million with the potential for additional income from licensing to third parties. 

Scientists in Atlantic Canada say they have found a gene that may play a role in skin aging. Researchers were investigating the genetic cause of a rare disorder known as cutis laxa type 2 (CL2), which causes skin on the hands, feet and face to be loose and older looking, as well as growth and developmental delays including effects on the brain. In the process, researchers found some interesting correlations with the synthesis of proline, a chemical associated with skin and joint health.

Several maritime Canadian families with CL2 were identified by clinicians at the IWK Health Centre’s Maritime Medical Genetics service.

You want to live healthier and probably look better; that's a good start.  Diet popularity can either be a sign that something works or an indication that people believe in crazy stuff.   Either way, it can't hurt to spend 5 minutes reading an article on the Internet before you commit.

A site called Realbuzz.com says it has put popular dieting approaches to the test - giving you the pros, the cons and each one has been rated on how they satisfy hunger, their ease to follow, expense and most importantly - the impact they can have on your overall health.

Accera, Inc., a biotechnology company delivering therapies in central nervous system diseases, today announced further evidence for genetic interactions impacting the efficacy of the ketogenic compound AC-1202 (Axona(TM)) in Alzheimer’s disease.

New data from the company’s previously completed double-blind, placebo-controlled trial in patients with mild-to-moderate Alzheimer’s disease demonstrates an interaction between two genetic markers that strongly influence the therapeutic response in patients. Dr. Samuel Henderson, Executive Director of Research, will present these results at the 2009 International Conference on Alzheimer’s Disease (ICAD) sponsored by the Alzheimer’s Association.
