Caffeine + alcohol keeps your chromosomes just rightSome telomeres are too long, and some are too short. Perhaps striking the right balance of caffeine and alcohol is the key to keeping them just right—as if you needed an excuse to have another hot toddy.
Cicadas having a blast this year
Experts say the class of 2013 is already larger and louder than anything NSW has seen or heard for at least 10 years.
I appear to have had my notes interrupted by an inconvenient in-text dragon's nose. I hate it when that happens.

This is really bad news. This appears to be Google dumping the only tool they really have for an open format in favour of...what? RSS is still useful and relevant it quite honestly doesn't matter that it's a geek thing, it powers how things like iTunes and podcasts work, and that's not just a geek thing.
... Are where I draw breath. When no-one else is awake in the house or when there is ten minutes between tasks or appointments. That time in which one can have a cup of coffee and collect disparate thoughts together. They make the rest of the day tolerable.
Rather than filing the day with activity from start to end these times feel like they need to be valued as things in themselves to foster balance and focus. Have a cup of tea rather than making that phonecall that isn't really that urgent. Instead of filling these times by grabbing your mobile and jumping on Facebook or tweeting something no-one will read, look around, take a deep breath and just do nothing. Feel how the thoughts slowly start to flow back? Good, isn't it?

Why eating ice cream gives you brain freezeClipped from: http://www.telegraph.co.uk/science/science-news/9219371/Why-eating-ice-cream-gives-you-brain-freeze.html |
They hope to use the discovery to develop new treatments for migraine.
The instant headache brought on by ice cold food and drinks is the bane of the summer with ice-cream lovers often seen clutching their foreheads waiting for the gripping pain to ease.
Scientists have noticed that migraine sufferers are more prone to 'brain freeze' and wondered if the phenomenon could be turned to their advantage.
In experiments carried by a researchers at the National University of Ireland in Galway and Harvard Medical School a team of 13 healthy volunteers deliberately induced the brain freeze so the effects could be studied.
It was found that the pain was brought on by a rapid increase in blood flow through a major blood vessel in the brain, the anterior cerebral artery.
The ache subsided again once blood flow was restricted.
The findings were presented at the meeting Experimental Biology 2012 being in San Diego.
By bringing on brain freeze in the laboratory the researchers were able to study a headache from beginning to end without the need for drugs that would mask the causes and symptoms of the pain.
The volunteers drank iced water through a straw that was pressed against their palate and then drank water at room temperature.
Blood flow was monitored using a hand held Doppler.
It was found that the anterior cerebral artery dilated rapidly and flooded the brain with blood in conjunction to when the volunteers felt pain. Soon after this dilation occurred, the same vessel constricted as the volunteers' pain receded.
Co-author Jorge Serrador of Harvard Medical School and the War Related Illness and Injury Study Centre of the Veterans Affairs New Jersey Health Care System, said: "The brain is one of the relatively important organs in the body, and it needs to be working all the time. "It's fairly sensitive to temperature, so vasodilatation might be moving warm blood inside tissue to make sure the brain stays warm."
But because the skull is a closed structure, the sudden influx of blood could raise pressure and induce pain, he said.
By constricting the blood vessel again the body could be acting to reduce the pressure before it reaches dangerous levels, he said.
Similar alterations in blood flow could be at work in migraines, post traumatic headaches, and other headache types, he added.
If further research confirms these suspicions, then finding ways to control blood flow could offer new treatments for these conditions. Drugs that block sudden vasodilatation or target channels involved specifically in the vasodilatation of headaches could be one way of changing headaches' course
