Science Blogs, Favourites of 2007

-------------------- Dec 27, 2007 Science Blogs, Favourites of 2007 Posted in Geek at 1:00 pm by David Bradley -- Click to comment In an effort to keep Sciencebase bubbling along during the holiday season, I figured a quickie post listing some of my favourite science blogs from this year might be interesting. Blogs come and go, of course, and my newsreader account is in constant flux with new blogs that catch my attention briefly getting pole position and then dropping off. However, I remembered that there is a quicker way for you to grab a recent snapshot of my feed favourites and that is with my newsfeed OPML file (right-click and save the link with an “.opml” extension. You can then import it into any compatible news aggregator, offline (Snarfer) or online (Google Reader) with minimal fuss. [lien] [EN]

Popular Science Discoveries This Year

-------------------- Dec 29, 2007 Popular Science Discoveries This Year Posted in Science at 1:00 pm by David Bradley -- Click to comment No science blog would be fulfilling its annual duties if it didn’t provide an end of year round up of what’s been hot and what’s been not in the past year. So, I activated Alex King’s excellent Popularity Contest plugin (new version out now) to find out what Sciencebase readers have been reading the most on the site over the last 365.256363051 or so days. So, here’s the top ten. · Potato powered mp3 player - a video spoof on lighting a bulb with a lemon battery, don’t try this at home! · How does salt affect the boiling point of water - a perennial question in science class. · Obesity gene - is hereditary to blame for overweight? · The secret of Newton’s laws explained with Lego .

Sciencebase Top Ten Molecules of 2007

-------------------- Dec 10, 2007 Sciencebase Top Ten Molecules of 2007 Posted in Chemistry at 4:00 pm by David Bradley -- 4 Comments Everyone loves a list. (Don’t they?) Well, as we’re approaching the end of the year and some of us are well into the panto and party season already, I thought it would be a good idea to run down a hit parade of this year’s molecules. So, here’s the Sciencebase Top Ten Molecules of 2007: · 10 - Graphene - chicken wire carbon sheets hit the headlines this year and will continue to do so as researchers learn more about this unique material’s optical and electrical properties. One day, carbon may even replace silicon as the elemental of choice in computing. · 9 - Helium - obviously not a molecule, but at the time of writing physicists in Canada had taken an important step towards understanding supersolidity in helium.

8 Squeezes for Your iPhone Battery

-------------------- Dec 5, 2007 8 Squeezes for Your iPhone Battery Posted in Geek at 4:00 pm by David Bradley -- 8 Comments If you’ve just bought an iPhone, you’re probably expecting many happy years of battery power. Well, not so fast. Laptop batteries are very similar to rechargeable batteries in other devices, they wear out. I’ve had my current laptop for about 18 months and in the last few weeks I’ve noticed that I’m not getting quite the battery life from it that I was when I first bought it. I used to be able to run for about 3 hours doing wordprocessing, email, and web browsing even on a wireless connection. Lately, however, the lithium battery seems to run down within an hour or so, which is a real pain when I’m offsite. I checked out Battery University to see if there is anything I can do to get my battery life back to normal. [lien] [EN]

December Chemical Discoveries

-------------------- Dec 21, 2007 December Chemical Discoveries Posted in Chemistry at 1:00 pm by David Bradley -- Click to comment In addition to my interview with Chinese chemist Andrew Sun, mentioned earlier this week, the December issue of Reactive Reports features the pick of chemistry news  DNA Nanorings  A simple approach to making rigid DNA nanorings with tailor-made functionality has been developed by Michael Famulok and his team at the University of Bonn, Germany. Sunshine Superpower  In the depths of the Northern winter, as we approach the shortest day of the year, what could be more welcome than a little sunshine news. Five Firsts in Chemistry  With 2007 rapidly coming to an end, the inevitable lists are popping up. Not wishing to be left out this holiday season. [lien] [EN]

Ten Computing Tips

-------------------- Dec 20, 2007 Ten Computing Tips Posted in Geek at 12:00 pm by David Bradley -- 2 Comments Seeing as the holiday season is fast approaching, I thought I’d offer an extra post covering some of the browsing and blogging tips and tricks I run on the Significant Figures site at Sciencetext.com. On that site I used to mainly discuss inappropriate unit conversions, sloppy statistical use, and dodgy typos in the media and still do occasionally. For instance, there was a lot of press on the comet bigger than the sun issue recently, which interconverted miles and kilometres with astoundingly high improvements in significant figures. Then there was the discussion of how much does Santa Claus weigh… But, like I say, mostly it’s tips on how to get the most from your web browser. [lien] [EN]

Composting Chitosan Cat-litter Composite

-------------------- Dec 19, 2007 Composting Chitosan Cat-litter Composite Posted in Science, spectroscopy at 4:00 pm by David Bradley -- Click to comment That has to be the oddest blog headline I’ve come up with this week, but it’s not in fact that esoteric once you get down to it. Basically, researchers in China have created a new material based on dolomite (porous kitty litter material) and the crab shell derivative chitosan. The new composite material not only absorbs water it can release an NPK (nitrogen, phosphorus, potassium) fertiliser over a prolonged period for use in agriculture and horticulture. Advantages are, improved irrigation efficiency and less run off into waterways together with improved crop yields. More on this, in my SpectroscopyNOW column this week and you get a chance to see a photo of my kitty too. [lien] [EN]

Male Semen is Redundant

-------------------- Dec 18, 2007 Male Semen is Redundant Posted in Geek at 8:30 pm by David Bradley -- 10 Comments You’ve seen the kind of thing: “Warehouse Razed to the Ground in Fire”, as if razing didn’t already mean the building was levelled. Worse, “Balloon Ascends Up into the Air”, ascending down is very difficult, simultaneously, at the same time, if not impossible; so too is descending up. However, the award for the most redundantly tautological headline of the year has to go to Scientific American for Male Semen Makes HIV More Potent, that’s male semen as opposed to the female variety, is it? It’s an important discovery, nevertheless that a chemical constituent of semen affects the immune system facilitating viral infection. Scientific American is probably not the first and original nor the ultimate and last publication to use this phrase though. [lien] [EN]

David Bradley Abbreviated

-------------------- Dec 17, 2007 David Bradley Abbreviated Posted in Science at 11:30 am by David Bradley -- 4 Comments I wrote a rather vainglorious post on my Significant Figures site last week - entitled David Bradley: Killer, Lover, Player Puller, it was basically an excuse to do a bit of personal branding but also highlighted the fact that there are so many other David Bradleys out there, including dozens of professors, photographers, a porn star, actors and tractors, and worst of all at least one lawyer. One of my virtual friends on StumbleUpon, spostareduro, picked up on this article saying it was a great idea for branding. In an email chat though she asked “Do you know how nifty it is to have initials that stand for Data Base.” Obviously, I was aware of this…it was part of the underlying psychology of morphing Elemental Discoveries into Sciencebase when I registered this website’s domain in 1999.

Could Warm Feet Save the World?

-------------------- Dec 14, 2007 Could Warm Feet Save the World? Posted in Science, Environment at 4:00 pm by David Bradley -- 4 Comments Wind turbines, photovoltaic power cells, wave energy, porous hydrogen storage composites for fuel cells, carbon sequestration, nuclear, even the idea of damming the Red Sea for a massive hydroelectric power plant are among the high-tech approaches being developed in the battle to reduce our collective size 9 carbon footprints to mere tiptoes. Saving energy and reducing emissions does not have to be about high tech and macro engineering. The developed world is unlikely ever to give up its dependence on personal motor transport, frequent and pointless air travel, patio heaters, high-definition DVDs, hot and cold running water, and countless other energy.

Volcanoes, Moons, Pearls, and Alchemy

-------------------- Dec 12, 2007 Volcanoes, Moons, Pearls, and Alchemy Posted in Science, Chemistry at 4:00 pm by David Bradley -- Click to comment This month’s physical sciences Spotlight over on the Intute site turns on oceanic plans, lunar volcanoes, and pearl necklaces: Infertile Global Warming Plan - Plans to fertilize the oceans with iron or other nutrients in order to absorb atmospheric carbon dioxide and so ward off global warming are not viable according to a report from researchers at Stanford and Oregon State Universities. Buckyball Pearl Necklace - A new type of polymer material made by stringing together the tiny football-shaped fullerene molecules has been synthesised by chemists in Spain.

Youtube for Scientists

-------------------- Dec 7, 2007 Youtube for Scientists Posted in Science at 4:00 pm by David Bradley -- 3 Comments Regular readers will know that I have a penchant for posting science videos every now and then. I’ve written about vids on how to explain Newton’s laws with Lego, A spoof sweet potato battery to power your mp3 player, Einstein meets Hendrix, and desktop hockey with one of the most water-repellent materials ever invented from chemists at Queen’s University Belfast. Youtube has long since been oustripped as the place to go for science-related videos, there are dozens of sites that specialise in science videos: Science Hack, for instance, showcases hundreds of videos every one of which has been screened by a scientist to verify its accuracy and quality. Typical searches include Hubble. [lien] [EN]
