Ever since the 1966 Hollywood movie "Fantastic Voyage",  written by Harry Kleiner (with what is actually a pretty good novelization by Isaac Asimov afterward) and starring Raquel Welch as the most convincing portrayal of a scientist ever , doctors have sought a day when they could have access to the real thing – a medical vehicle shrunk small enough to "submarine" in and fix faulty cells in the body.  According to new research by Tel Aviv University scientists, that may be only three years away. 

Blasting biofuels for significantly contributing to greenhouse gas emissions is sooooo 2006, according to a new Michigan State University analysis.   Much like the environmental hype in the 1990s about how much better we would be with ethanol, the scorn heaped on biofuels has been exaggerated as well, calling into question the benefits of making fuel from plant material.

The scorn comes from assumptions that may not be correct, write Bruce Dale, Distinguished Professor of chemical engineering and materials science, and co-authors in Environmental Science&Technology.

The downside to new antibiotics is that bacteria think of new ways to become resistant to them.    While resistant bacteria continue to increase, scientists keep searching for new sources of drugs in this week's Journal of Biological Chemistry, one potential new bactericide has been found in the tiny freshwater animal Hydra.

The protein identified by Joachim Grötzinger, Thomas Bosch and colleagues at the University of Kiel, hydramacin-1, is unusual,  and clinically valuable, as it shares virtually no similarity with any other known antibacterial proteins except for two antimicrobials found in another ancient animal, the leech.


Not this Hydra.

In our 'studies you don't need to read' category is this bit of economic insight from the February edition of Addiction;  the more alcoholic beverages cost, the less likely people are to drink. And when they do drink, they drink less.

After analyzing 112 studies spanning nearly four decades, researchers documented a concrete association between the amount of alcohol people drink and its cost. 

Yes, it was unclear before that we should make alcohol something only rich people can have, thus widening the social and cultural gap before have's and have not's even further.

HUMANS have actively changed the coats of domestic animals by cherry-picking rare genetic mutations, causing variations such as different colours, bands and spots, according to a new study. 

Although the study was carried out on pigs, the results can explain the evolution in the coat colors of all domesticated animals as they all express the same melanocortin-1 receptor (MC1R) gene, one of the genes that controls coat colour in animals. 

The study also explains for the first time why there is a stark contrast between the coat colors of wild and domestic animals and gives further insight into the process of evolution, particularly since animals were first domesticated about 10,000 years ago. 

An ounce of prevention is worth a pound of cure, according to Ben Franklin. But what if the prevention causes more harm than benefit? And what if the prevention doesn't prevent much of anything at all?

Pain clinics and physiotherapists have been using large, complex pieces of equipment with cables to relieve back or joint pain but a company says they have developed a breakthrough in anti-pain treatments. They claim people suffering from headaches will soon be able to use this technique to treat them at home rather than depend on drugs with numerous side-effects.

The technique is called CEFALY(R) and was demonstrated for the first time at the international medical fair MEDICA in Düsseldorf last November. A polish company (Medic-Mar http://www.medicmar.com.pl) has made Poland the first country where Cefaly is available for patients suffering from headaches.

They say their technological breakthrough is two-fold, involving miniaturization and perfect precision.

The pharmaceutical industry is currently facing some key challenges, like an increase in drug development costs, a decrease in the number of drugs being approved and scrutiny from regulatory authorities. Patients themselves are also demanding more effective and safer drugs.

Pharmacogenomics says they can help to guide drug development and therapy by correlating gene expression with a drug's efficacy.

A researcher from the University of Leicester has identified what looks to be the oldest archaeological evidence for chemical warfare--from Roman times.  At the meeting of the Archaeological Institute of America, Simon James presented CSI-style arguments that about twenty Roman soldiers, found in a siege-mine at the city of Dura-Europos, Syria, met their deaths not as a result of sword or spear, but through asphyxiation.

Adelaide researchers say they have made a world breakthrough in treating premature babies at risk of developmental disorders.  A six-year study led by Dr Maria Makrides from the Women's and Children's Health Research Institute and Professor Bob Gibson from the University of Adelaide has demonstrated that high doses of fatty acids administered to pre-term infants via their mother's breast milk or infant formula can help their mental development.

The findings were published today in the Journal of the American Medical Association (JAMA).
