Olive Oil – News Flash – It’s good for you!
Scientists may have found out how Olive oil reduces the effect of Alzheimer’s disease. So go ahead, pour it on everything!

Look out! That algae is a gene thief!
The red algae Galdieria is capable of withstanding extreme, varied environments, and it appears as though it has adapted to its crazy lifestyle by stealing genes from bacteria and archaebacteria. Isn’t that cheating?

Blair’s Animal Corner
Inexperienced men are dangerous!
Sexually naive mice showed aggression, sometimes to the point of murder, when introduced to mouse pups. However, male mice that had some experience and had fathered mice before fell right back into paternal habits. Scientists found that the vomeronasal organ in reaction with pheromones from the pups were to blame. Of course, it all coms back to hormones…

Get Up-a-doodle-do!
A new study out of Japan shows that roosters crowing is the result of circadian rhythms and not at all related to seeing the sun rise, but much research is needed to see why they crow at other times of the day.

Who’s really in charge of your brain?
A new study out of Berlin has found that the unconscious part of our brains may make a decision up to four seconds before our conscious “makes” it. So, do we have a choice at all, or are we all slaves to our reptilian counterparts?

Time to fix the NCAA!
The Georgia Tech’s LMRC has chosen Florida to win out this year, so if you trust a computer, place your bets now!

The Universe: even older than we previously thought
The most detailed picture yet of the cosmic wave background came from the Planck this week. It turns out the universe is older than we previously though, at around 13.81 billion years. Happy belated birthday, universe!

British water voles need a hand – or rather, a ladder…
Water Voles in the UK have declined in number by 90% since 1970 due to habitat loss and genetic bottlenecking. Now, british scientists are building the voles ladders to reach new waterways and potentially meet up with other populations in order to diversify the gene pool and increase habitat space. Here’s hoping they figure out how to use them!
