A couple of years ago, I re-posted an old article of mine about homeopathy discussing its ludicrous claims, its feeble attempts to provide a scientific explanation for those claims, and basically pointing out that no solid evidence has ever been found that infinitely diluted solutions of spurious ingredients have any more beneficial effect on a patient than a glass of fresh water….

Time to bring you up to date on the latest science headlines I’ve put together for other sites this last couple of weeks, so here’s a quick round-up:
On the SpectroscopyNOW site, this issue, I covered natural chemicals that can help sunflowers soak up toxic cadmium from the soil (another example of the phytoremediation process I discussed in more detail on Sciencebase.com recently). I also …

The wastewater released from industry often contains high levels of toxic heavy metals, which can kill organisms, damage ecosystems, and accumulate in the foodchain. Electroplating, lead smelting, mining, and countless other processes produce enormous volumes of such wastewater.
In a perfect world, remediation would be powered by a renewable energy supply, there would be no solid waste to dispose of, and the heavy metal contaminants could be recycled back into the industrial process with minimal losses. …

Juggling matters on the brain – UK scientists have used magnetic resonance imaging to reveal that learning a complex task like juggling can causes changes in the white matter in the brain. The findings could have implications for developing new approaches to neurodegenerative diseases, such as multiple sclerosis.
Cancer transition – Anticancer drugs for treating ovarian and colon cancer could use rare metals as weapons in the …

Twenty years ago today, my girlfriend (now my wife) and I lay on a bed in a cramped backpackers’ hostel in the Katherine Gorge National Park (now Nitmiluk), in Australia’s Northern Territory, watching news of the fall of the Berlin Wall (now rubble). Outside insects were buzzing ferociously, the temperature was in the high 30s, and the hostel owner told us that he wouldn’t bother going in the (tiny, dirty) pool unless the temperature in …

In the current issue of The Alchemist we learn how to stick methane molecules to metals without breaking carbon-hydrogen bonds and how to make impossible carbene catalysts without the usual prerequisite of an attendant metal centre.
Another seeming impossibility comes to light: a new microscopy technique for visualizing non-fluorescing biomolecules using the kind of stimulated emission suggested by Einstein almost a century ago.
An exchange program leads …

Laura Bonetta wrote an excellent article for the science journal Cell recently in which she quoted various science types who use Twitter on the subject of whether or not scientists should be tweeting. It’s a topic I’ve discussed more generally regarding scientists’ use of social media and online networking communities.
Anyway, she asked my opinion on a few matters regarding twitter and …
UPDATE – NOV 5: Still working through the almost 650 members of the list, but now up to the P’s.
Pressure was on from lots of science tweeps for to categorise my scientwist list…so I’ve made a start.
The spillover (lots of tweeps in the T to Z group from the TweepML.org version of my scientwist list have now each been given a category as I cannot squeeze them into the 500 limit for the …

Regulars will know that I’ve compiled and recompiled lists of science types on Twitter for mutual benefit. It started out as a list of 100 of my own Twitter friends back in January 2009, who happened to be in science and gradually grew to well over 600 members by November 2009.
However, just as I migrated the old manual list to Tweepml.org to help automate bio and avatar updates, Twitter announced the release of its …
