Jet lag occurs when your body's circadian rhythms fall out of sync with your surroundings, such as when you quickly move to an area that is 12 hours behind where you were previously. One thing that certain helps to adjust is exposure to sunlight--cells in your retina use this information to tell the brain that it is daylight, and that the body should be awake. But how much sunlight does the body need to adjust? And at what times?
Think of it as a study of the natural behaviours of the troll. A team of information science researchers recently analysed the comments people make on recorded TED talks. Actually, the researchers found that the majority of comments related to the content of the talks (progress!). But they also found that about six percent of YouTube comments on TED talks are insults and that female TED presenters are more likely to have commenters assess their appearance and style than male presenters (not progress).
Before the Predator attached the name "drone" to an anti-terror war machine, many militaries flew unmanned planes as targets, so that pilots and anti-aircraft gunners could practice shooting moving objects. Target drones are still flown today, both specific target models and ones converted from old jets specifically for this purpose. In the past, targets were generally plane-sized, and militaries used anti-aircraft weapons to shoot them down.
English philosopher Thomas Hobbes believed that men living in anarchy would lead “solitary, poor, nasty, brutish, and short” lives. So as much as I’d enjoy rebuilding civilization from piles of trash after an apocalypse, I’d first worry about a way to send petrol-marauding punk rockers scrambling and make infectious zombies take a dirt nap.
The judgement is likely to influence a crucial government review which is deciding whether the 30 per cent tax rebate for private health insurance coverage ofcomplementary therapies should continue. Australians spend almost $4 billion a year on complementary therapies like vitamins and herbs and almost $10 million on homeopathic remedies.
For nearly half a century, social scientists have operated under the assumption that all basic human emotions are universally recognizable. Countless cross-cultural experiments—not to mention a few television shows (eg Lie to Me)—have both directly and implicitly referenced the notion that every person on earth expresses facial emotion in the same way. Regardless of cultural context, we can all interpret happiness, sadness, anger, fear, and disgust in the expressions of the people around us... right?
This latest design for growing vegetables in space is a bit prettier than its predecessors. This is a collapsible growth chamber made by Orbital Technologies Corporation in Wisconsin. The lettuces inside live in individual "plant pillows." NASA plans to send the chamber and the plant pillows to the International Space Station on April 14, aboard a SpaceX launch.
When people review cheap restaurants in particular on Yelp, they often use drug metaphors, and speak in the language of addiction. This is but one of the interesting findings of a linguistic study of 900,000 restaurant reviews on Yelp.com. The researchers found that these reviews offered a unique look into the human psyche... and how much people love references to drugs and sex (representatives for the sadly snubbed rock 'n roll couldn't be reached for comment). Here are some of the other patterns found, as described by Stanford University:
Look at a kid under the age of five, and it's hard to imagine what he'll look like in 70 years. But this new piece of software does just that. Check out this series of photos, which compares actual photos of a boy as he grows up (photos on the right) with photos generated by the new aging software, using only the three-year-old picture as a reference (photos on the left).
This material can hold several times its weight in water, and unlike the polymers that currently make up absorbent material in diapers and other products, breaks down in about 30 days. The product owes is absorbent abilities to its cellular structure of jellyfish bodies. “Jellyfish are marine creatures composed of 90 percent water and that live in water," according to Capital Nano, a company funding Cine'al. "Their bodies are formed from material that can absorb high volume of liquids and hold them without disintegrating or dissolving."
So. Yes. A team of doctors is reporting that they grew vaginas in a lab and implanted them in four girls who had underdeveloped vaginas and uteruses because of a rare genetic condition. This is the first time anybody has reported growing vaginas in lab for human patients. About seven years after their initial surgeries, the girls are grown up and doing well. Two of the four could theoretically have children, although neither has reported yet she is pregnant.
