Science isn’t just for the laboratory and the classroom: It’s also for big-screen theaters and video games, as demonstrated by the winners of this year’s International Science and Engineering Visualization Challenge.
“The winners made scientific data beautiful and brought their new ideas to life, while at the same time immersing the viewer in science,” Monica Bradford, executive editor of the journal Science, said in Thursday’s announcement of the awards.

Researchers looking for simple ways to treat autism say they may have explained why at least some cases occur: It all has to do with the stress babies undergo at birth.
They’re already testing a simple drug for treating kids with autism and say their findings may point to ways to treat the disorder earlier in life.
It’s all experimental, but the study, published in the journal Science, should inspire other researchers to take a closer look. “This is exciting stuff to people in the field, because it’s getting at a basic mechanism,” says Andrew Zimmerman of the University of Massachusetts Medical School, who reviewed the study.

Even our brains need to take out the trash.
Researchers from the University or Rochester Medical Center found that a waste-flushing system in the brain, called the glymphatic system, is most active when we sleep — nearly 10 times more so than during periods of wakefulness, in fact.
Plus, during sleep, brain cells shrink in size by 60 percent to better allow for the removal of waste from the brain.
“This study shows that the brain has different functional states when asleep and when awake,” study researcher Maiken Nedergaard, M.D., D.M.Sc., the co-director of the university’s Center for Translational Neuromedicine, said in a statement. “In fact, the restorative nature of sleep appears to be the result of the active clearance of the by-products of neural activity that accumulate during wakefulness.”
The findings, which are published in the journal Science, are based on brain imaging experiments in mice, using technologies such as two-photo microscopy. Researchers found that when the mice were put to sleep, cerebral spinal fluid is ushered through their brains through this waste-removal system, which then moves toxins to the circulatory system and the liver.

Researchers at Stanford University announced this week that they’ve created genetic receptors that can act as a sort of “biological computer,” potentially revolutionizing how diseases are treated.
In a paper published in the journal “Science” on Friday, the team described their system of genetic transistors, which can be inserted into living cells and turned on and off if certain conditions are met. The researchers hope these transistors could eventually be built into microscopic living computers. Said computers would be able to accomplish tasks like telling if a certain toxin is present inside a cell, seeing how many times a cancerous cell has divided or determining precisely how an administered drug interacts with each individual cell.
