Shuntros writes “BBC News is reporting progress from scientists at Harvard Medical School towards strangling the growth of cancer cells. By starving cells of a certain type of enzyme, growth essentially ceases. ‘The fact that proliferating cancer are able to consume glucose at a much higher rate than normal cells was first discovered by the German Nobel prize-winning chemist Otto Warburg more than 75 years ago. He also showed that the amount of glucose the cells needed to keep their vital signs ticking over was minimal, allowing them grow and divide at the prodigious rate usually associated with foetal cells.’ Certainly not a cure by any stretch of the imagination, but putting the brakes on cancer growth in this way is very much akin to the revolution that was AZT.”

esocid tips us to news out of Duke University Medical Center, where researchers have discovered a type of microRNA that’s related to the capability of zebrafish to regenerate lost or damaged organs. This is the result of a study initiated after it was discovered that zebrafish were able to recover from “massive injury” to the heart through their own regenerative biology. The scientists hope to be able to use this information to bring about similar healing in humans. Zebrafish have also been helpful in cancer research. “In zebrafish, one or more microRNAs appear to be important to keep regeneration on hold until the fish needs new tissue, the Duke researchers state. In response to an injury, the fish then damp down levels of these microRNAs to aid regrowth. Poss and many other cell biologists believe that mammals may have the same tissue regeneration capability as zebrafish, salamanders and newts, but that it is locked away somewhere in our genome, silenced in the course of evolution.”

Ars Technica brings word that Google Sky, formerly only available as an extension of the Google Earth software, is now accessible through your web browser. The interface of Google Sky is quite similar to that of Google Maps, complete with search and alternate views by spectrum. The story also mentions (and more importantly, links) ten of the more interesting sights. We discussed Google Sky’s initial release last year. Quoting: “Visible light only shows us a small picture of the entire universe; non-visible spectra such as ultraviolet (UV), infrared and X-ray hold a whole other world of information. Here is where Google Sky becomes very cool. There are three more sections that highlight fantastic images from the Chandra X-Ray Observatory, the GALEX Evolution Explorer (UV), and the Spitzer Space Telescope (IR). What makes these very cool is that under each selected body there’s a slider that’ll change the displayed image back and forth between the visible and invisible spectrum.”

An anonymous reader writes “The question of global population is a pretty crucial one; how many people will there be in ten years? In forty? The New York Times notes research done by a group called the Worldwatch Institute, research that concludes world population figures are too fluid to make any sort of educated guesses. Childbearing populations combined with severe resource shortages in some parts of the world make pinning down a global headcount unfeasible for ten years from now, let alone out to 2050. The article continues beyond its original borders, as well, with commenters in the field of population studies noting we don’t even have a good grasp on how many people were alive in 2007.”
