From Geeks are Sexy Technology News: Scientist Discovers Ant Art

Today I tripped over a interesting application of science that will change how we look at our friend, the common house ant.

53 year old scientist Dr Mohamed Babu in Mysore, India was alerted to this phenomenon by his wife, who noted that when ants drank some spilled milk, their transparent rear segments would turn white.

Dr Babu decided to experiment with coloured sugar water and photographed the results. While the ants fed on the sweet liquid treats, they decorated their bums with the colour of their snack.


Honestly, this has absolutely no scientific application, but it does look pretty cool.

The effort that Dr Babu put in to the experiment is rather impressive. He discovered that the ants would gravitate toward the brighter colours, and found they only took up the blue and green droplets once the brighter droplets were too crowded. He had to develop a process where drops of different sizes were left in different locations of the paraffin observation area he crafted.

Also, if he didn’t get the picture he wanted Dr Babu would have to wait until the following day before the ants would return to feed.

Sometimes discovery can be fun, and I actually like the cute pictures of creepy little ants all decorated like they are supporting a sports team, or are from the same school.

I can just imagine these ants gossiping around the water drops: “I am eating the green stuff today. This is going to go straight to my ass!”

From Ars Technica: “We’ve observed a new particle”: leaked video reveals Higgs confirmation

“We’ve observed a new particle.” That’s the opening statement in a video featuring Joe Incandela, the spokesman for the Large Hadron Collider’s CMS detector, made in a video that is currently publicly accessible on the CERN website. The video, first spotted by ScienceNews and now apparently pulled, appears to preempt the big announcement scheduled for early tomorrow morning. It also implies that this year’s data was enough to push the evidence for the Higgs past the five standard deviations needed to declare discovery.

“When we say we’ve observed the particle, it means we’ve just got enough data to say it’s definitely there, and it’s very unlikely to go away,” Incandela says in the video. In addition, we know it’s a boson because it decays into two photons.
Its mass is roughly 130 times that of the proton, making it the heaviest boson we’ve discovered so far—and the heaviest particle other than the top quark.

The two-photon decay is one of the strongest bits of evidence, and provides a narrow peak that helps define its mass. Strong evidence is also available through decay into two Z particles; the signal is there in other decay channels as well, but those are less definitive because of the background noise present.

From Discover Magazine: Compressed Air Is Great for Powering Workshops. Can It Help Power the World? | 80beats

power grid

Despite increasing worry about what our energy consumption is doing to the planet, we’re also increasingly tied to power-hungry electronic devices. To keep reliable, renewable energy flowing, some suggest, we must give the power grid a makeover. And one method that could change it is a breath of fresh air. Danielle Fong and her company, LightSail Energy, want to store renewable energy in tanks of compressed air. Because wind and solar can be unpredictable energy sources, the ability to save any surplus for a windless or cloudy day makes them more reliable.

Caleb Garling has written about Fong’s unusual method of storing power for Wired’s World’s Most Wired feature.

In a way, Fong is going back to the future. Compressed air tanks have been used to store energy as far back as the late 19th century. They were installed in cities across the globe, from Paris to Birmingham, England to Buenos Aires. Germany has been using the technology for the past 30 years, and a power company in Alabama opened a facility in 1991. The idea is a simple one: If you have a power source — whether it’s gas or …
