Wow! Thanks. I’m happy that you like it :)

Scientists in the US have developed a calculator from living cells, using old-fashioned analog programming. Their hope is that the technology could be used in the future to program cells to kill cancer. Researchers have previously built electronic circuits using living cells. They achieved this by forcing living cells to behave in binary (digital) systems. But this is not energy efficient. And many cells are required to implement simple functions that transistors, the basic units of electronic […]

Burning tar sands = 'unsolvable' climate crisis: Hansen Climate change has shifted the North and South Poles Climate change is happening… So what? Fiji's villagers move uphill to escape rising seas Global warming has not stalled Go fish (somewhere else): Warming oceans are altering catches Ignoring the cost of climate change is bad business Mount Everest's ice is melting Profits vs. disaster in Arctic meltdown Warmer springs linked to dwindling snow in Rocky Mountains Why we know about […]

Greetings one and all, and a very happy science Sunday to you! This week’s generally been quite interesting. We’ve had good news, bad news, a little heated discussion… All the kind of things which keep the science community vibrant and [...]testThe post Weekly Science Picks appeared first on Australian Science.

On Thursday we lowered a camera into an ice borehole to get a look at the underside of the ice. In the following video, you can clearly see the algae living in the bottom of the ice due to their pigments, which they use to harvest light. These organisms are not frozen into the ice; [...]
