Software lets researchers create tiny rounded objects out of DNA. Here’s why that’s cool

Posted by in categories: biotech/medical, nanotechnology

Marvel at the tiny nanoscale structures emerging from research labs at Duke University and Arizona State University, and it’s easy to imagine you’re browsing a catalog of the world’s smallest pottery.

A new paper reveals some of the teams’ creations: itty-bitty vases, bowls, and hollow spheres, one hidden inside the other, like housewares for a Russian nesting doll.

But instead of making them from wood or clay, the researchers designed these objects out of threadlike molecules of DNA, bent and folded into complex three-dimensional objects with nanometer precision.

NASA Telescopes Reveal Black Hole Tearing Apart Star

Posted by in category: cosmology

Observations from NASA reveal how complex and catastrophic an event it can be when a star gets too close to a black hole, CBS News reported on Wednesday.

Such an event does not occur in a single moment but, according to NASA, can take several months as the black hole’s gravity slowly sucks in the star’s being.

The latest such observation, which took place over a period of more than five months, was watched by multiple telescopes, NASA’s Jet Propulsion Laboratory reported.

One dietary mineral could prevent cognitive decline, study shows

Posted by in categories: food, health, neuroscience

You may have heard the phrase, “You are what you eat.” It’s no surprise that what you put into your body directly impacts how you feel and other aspects of your health, including cognitive function.

In fact, diets that contain certain amounts of minerals like sodium and potassium could have an effect on brain function, especially in older adults, according to a recent study published in Global Transitions.

Researchers from China found diets higher in sodium were associated with a higher risk of cognitive decline and poor and deteriorated memory. On the other hand, participants in the study who had more potassium intake in their diet were associated with higher cognitive function.

Standard Model survives its biggest challenge yet

Posted by in category: futurism

For years and over three separate experiments, “lepton universality” appeared to violate the Standard Model. LHCb at last proved otherwise.
