A fairytale — How to (or how not to) give an effective PowerPoint presentation

***This blog has moved to a new location. Visit the new site for more posts and updates! (http://www.SomethingAboutScience.com)***

If I asked you to think of a scientist, you probably imagined a madman wearing a dirty lab coat and holding test tubes. Another cliché is a scientist giving a boring and mind-numbing presentation. (By the way, being a researcher myself, I dare say that both examples here are quite often true…)

I came across a video recording of a talk sponsored by TEDxSingapore, which might help scientists beat the ho-hum-talk stereotype. This also would help anyone giving a presentation at school or at work. In the talk entitled, The Princess, the Witch, and the PowerPoint, Coleman Yee uses a fairytale analogy to show us how people often misuse PowerPoint.

Coleman Yee’s talk is quite amusing and worth watching. Enjoy! Watch the video –>

140 years after a giant squid attacked the submarine Nautilus in Jules Verne’s masterpiece, the formidable creature has finally been caught in the act.

A giant squid in its deep-sea habitat was captured on camera for the first time ever, thanks to the efforts of the joint expedition consisting of scientists led by a Japanese zoologist, Japanese filmmakers and broadcaster, and the Discovery Channel.

After the first photographs of the giant squid in the deep water appeared in 2004, obtaining video footages of the creature in its habitat had remained a challenge. The mission took the team 100 dives and 400 hours of recordings to succeed. The video was taken last summer (July 2012) in the Pacific Ocean – 1000 kilometers (600 miles) south of Tokyo, at the breath-taking depth of up to 900 meters (2950 feet). Watch the video –>

Poison? Potion? — Snake venom as heart attack treatment

Snakebites can be deadly, but their poisons could be a lifesaver.

Eastern green mamba

This glossy green snake is an Eastern green mamba (Dendroaspis angusticeps), found throughout the eastern Africa. Don’t be fooled by its lack of flashy red stripes or other visual warnings: its bites are highly poisonous. While you would want to avoid venomous snakes like the green mamba out in the wild, they are a treasure trove for some medical researchers. Continue reading –>
