Submission + - Bacteria behaviour can shed light on how financial markets work (theconversation.com)

Submitted by notscientific
notscientific writes: Bacteria invest in proteins in an attempt to reduce stress or increase energy intake, while humans invest in cash. In both cases, better tradeoffs pay off. The similarities in tradeoffs faced by both bacteria and humans during investment are actually quite similar. Now, using synthetic biology, a group of scientists has shown that the outcomes of investment decisions in bacteria can be precisely defined, alluding to the idea that human investment activities, such as financial markets, can be thoroughly understood as well, and even modelled.

Submission + - Unique howls are what wolves use as names (theconversation.com)

Submitted by notscientific
notscientific writes: Each wolf has a unique howl, which scientists can now decipher through voice recognition, allowing them to identify wolves individually. The scientists developed sound analysis code that can tell which wolf is howling with 100% accuracy. Previously, pitch was used to tell wolves apart, but these only achieved a relatively low accuracy rate. This sound analysis is important because it could well give researchers the first proper way to effectively monitor wolves in the wild. Interestingly, this research comes after the recent finding that dolphins have names for one another. In the case of wolves, their howls are essentially their names.

Submission + - There's enough wind energy to power Earth 200x over (nature.com)

Submitted by

notscientific writes: "Renewable sources of energy are obviously a hit but they have as yet failed to live up to the hype. A new study in Nature Climate Change shows however that there is more than enough power to be harnessed from the wind to sustain Earth's entire population... x200! To generate energy from the wind, we may however need to set up wind farms at altitudes of 200-20,000 metres. To be fair, the study is purely theoretical and does not look at the feasibility of such potential wind farms. Regardless, the paper does provide a major boost to backers of wind-generated energy. Because science has confirmed that the sky's the limit."
