Walking the Amazon
This is some project.
Earlier this year, Ed Stafford and Luke Collyer from the UK started an epic journey – to walk the full length of the Amazon from the source in Peru to the mouth in Brazil. This has never been done before and will cover 4,000 miles and take about 18 months. Their aim is to raise money and awareness for a load of charities, as well as serving as a spotlight on issues related to environmental and social change in the Amazon region.
Recently, Luke left the expedition after 90 days – so if you’re up to it, head on over to the website and apply for the position of Ed’s new partner!
The team are posting regular videos of their progress to the website, which can also be found on GoogleVideo:
edited to correct Luke Collyer’s name.
Shark vs Octopus – National Geographic Videos
1. Place bets.
2. Play video.
3. Oh yeah.
National Geographic have been playing the YouTube game for two years now and have posted over 600 videos on their channel. Just put ‘science’ into the search box to filter the videos.
TED – 50 million views young (and the best graphs EVER)
TED (Technology, Education, Design) has racked up 50 million views since 2006 and is proof that people can use the internet for more than just celebrity gossip and the dodgy sites. They now have a highlight reel of their top ten talks, including the $40 SMART Board, some oceany greatness and lessons learned while having a stroke. Ken Robinson’s talk is up there (are schools killing creativity?), and one of the coolest bits of statistics you’ll ever see from Hans Rosling:
After watching that, you should absolutely must head straight on over to gapminder.org and be dazzled.
You can even access the gapminder graph and manipulate both axes. Awesome.
Synthetic Biology – the man-made future?
Where’s the money in Biology? Probably where the future lies – genetics and synthetic biology.
As we learn more about genomes and the way different organisms (including pathogens) work, we can move towards creating targeted responses and DNA-level manipulation. Synthetic biologists take DNA and try to re-work it into a solution to a problem – by creating synthetic DNA, they hope to achieve control over the functions of the organism. They hope to generate alternative sources of fuel, targeted treatments and vaccines and many more applications.

BioBricks (company link) are a leading example of synthetic biology in action. Think of them like lego bricks or parts of standard computer code – you can take them and (theoretically) fit them into any genome. This is one of the wonders of DNA – base-pairings and the universality of the genetic code allow these researchers endless opportunities for tinkering and advancing science. Some BioBricks are ‘parts’, some are ‘devices’ and others are ‘systems’ – sections of code that increase in complexity and functionality.
There is an exciting world of information out there about this topic, and it’s well worth looking at if you think your future lies in biotechnology. It’s a discipline that pulls together Biology, Physics, Chemistry, Maths, Engineering and Programming, and the ways in are various. If you want to find out more about a career in synthetic biology, MIT are world-leaders in the field.
For a quick explanation of how synthetic biology works (and an interesting hardware/software analogy) watch the video from ScientificAmerican below:
You might also want to read ‘Prey’ by Michael Crichton for a bit of light holiday scare-mongering. Imagine ‘The Andromeda Strain‘ with nanoparticles.
And while we’re on the subject of Scientific American, you may as well check out their video channel on YouTube. It’s much like the NewScientist one.
Javanese White Rhino Filmed!
Yay!
Ujung Kulon national park – a reserve on the western tip of Java, home to a lot of protected wildlife and just a few hours from Bandung – has some young white rhinos! Thought to be on the verge of extinction, they are a sign of hope for the future.
My favourite part was the camera-smackdown at the end.
And whiie we’re on the subject of hope in the Indonesian environment, here’s news of a great success in re-introducing native species to cleared land, up in Borneo.
It makes me feel all warm and fuzzy.
Just to balance it with a bit of doom and gloom:
This recent story tells of the clearance of tropical forests to make way for palm oil. Boo!
And this one investigates the effects of Indonesia’s paper industry.
How can we make positive changes in our lives to create real, measurable improvements in the local and global environment?
Virtual Echocardiography
This resource from Toronto General Hospital’s Perioperative Interactive Education unit gives a good view of two sections through the heart, with ECG loops to match the image. Good for seeing the normal function of cardiac valves.
Updated and includes guide sheets, quizzes and a range of languages.
Dihybrid Crosses, Gene Linkage and Recombination
More links to be added very soon.
