Scientists have grown the first mini human brains in a laboratory and say their success could lead to new levels of understanding about the way brains develop and what goes wrong in disorders like schizophrenia and autism.
“It didn’t matter if their significant other was an excellent hostess or intelligent, men were more likely to feel subconsciously worse about themselves when their female partner succeeded than when she failed, according to the study published online in the APA Journal of Personality and Social Psychology. However, women’s self-esteem was not affected by their male partners’ successes or failures, according to the research, which looked at heterosexual Americans and Dutch.”
“In one case, the subject travelled to New York, demanding to see the ‘director’ of the film of his life, and wishing to check whether the World Trade Centre had been destroyed in reality or merely in the movie that was being assembled for his benefit. In another, a journalist who had been hospitalised during a manic episode became convinced that the medical scenario was fake and that he would be awarded a prize for covering the story once the truth was revealed. Another subject was actually working on a reality TV series but came to believe that his fellow crew members were secretly filming him, and was constantly expecting the This-Is-Your-Life moment when the cameras would flip and reveal that he was the true star of the show.”
John Nelson is known for building extremely complex visualizations of weather patterns. But his latest creation is a simple animated GIF of 15 frames from NASA’s cloudless satellite photography collection. It’s essentially a year in the life of Earth.
Here, he shares why the visual is so haunting to him personally and to us collectively. We felt that his thoughts were simply too earnest to abridge.
HOW MARS GOT ITS GROOVES BACK Dubbed linear gullies, these long grooves appear on the sides of some sandy slopes during Martian spring. They have nearly constant widths, extend for as long as two kilometers, and have raised banks along their sides. Unlike most water flows, they do not appear to have areas of dried debris at the downhill end. A leading hypothesis — actually being tested here on Earth — is that these linear gullies are caused by chunks of dry ice breaking off and sliding down hills while sublimating into gas, eventually completely evaporating into thin air. Or, there are aliens. Aliens on Mars. And these are the tracks of their peers. (Photo: HiRISE, MRO, LPL (U. Arizona) via NASA APOD)
The level of the most important heat-trapping gas in the atmosphere, carbon dioxide, has passed a long-feared milestone, scientists reported on Friday, reaching a concentration not seen on the earth for millions of years.
“…the current period is probably the temporal equivalent of flyover country. You might say, “What do you mean, it’s a time of unprecedented technological and cultural change!” Maybe so, you time-hick, but a small town in South Dakota that’s finally getting hooked up to teh internet or getting their first Olive Garden isn’t interesting to someone who already has ultra-fast broadband or lots of family-owned local Italian restaurants. You have to remember that these are people from the future. There’s nothing interesting to see here that they don’t already have. They have technology and civil rights and cuisine that you and I can’t even begin to imagine. You don’t visit small towns unless you have family still living there, and when it comes to time travel, family doesn’t really work that way.”
Why Evolution is True and Why Many People Still Don’t Believe It
Jerry Coyne, professor of Ecology and Evolution at the University of Chicago, reviews the evidence for evolutionary theory and why Americans (in particular) are so resistant to accepting evolution as fact.
Highly recommended watch, even if you consider yourself well-versed on the topic. The pace is brisk and he’s not boring at all, and I found myself learning a new thing or two. The final analysis won’t surprise many of you, but he takes great care in getting there.
In general, an excellent review for the 12% (an embarrassing figure) of Americans that accept evolution as fact, and time well spent for the rest having their convictions challenged.
