Yes, You’re Irrational, and Yes, That’s OK
Humans diverge from economic rationality. Researchers have found that all sorts of logically inconsequential circumstances—rain, sexual arousal (induced and assessed by experimenters with Saran-wrapped laptops), or just the number “67” popping up in conversation—can alter the value we assign to things.

Termites: Guardians of the Soil
Researchers at Princeton University and their colleagues recently reported in the journal Science that termite mounds may serve as oases in the desert, allowing the plants that surround them to persist on a fraction of the annual rainfall otherwise required and to bounce back after a withering drought. The mounds could thus prove potential bulwarks…

In Fake Universes, Evidence for String Theory
Researchers are demonstrating that, in certain contexts, string theory is the only consistent theory of quantum gravity. Might this make it true?

Massive project maps DNA tags that define each cell’s identity
Our DNA may encode all the instructions needed to build the human body and keep it running, but each of our cells must follow just a subset of those instructions in order for the body to work properly. Thanks to the $300 million, National Institutes of Health (NIH) Roadmap Epigenomics Project, researchers have now identified…

Study Says Organic Milk Offers No Nutrition Boost
People choose organic dairy products for any number of reasons, including their perceptions on the environmental impacts of dairy farming, the treatment of cows, and the safety of milk from cows given antibiotics or extra hormones. Consumers may also think organic milk offers better nutritional content than conventional milk. However, in a review of almost…

How Henry Cavendish Used a Wire to Measure a Tiny Force of Gravity
The crowning achievement of the 18th-century researcher was the design of the first experiment to measure the force of gravity between masses in a lab

Turning Carbon Dioxide Into Rock, and Burying It
In a test that began in 2012, scientists had injected hundreds of tons of water and carbon dioxide gas 1,500 feet down into layers of porous basaltic rock, the product of ancient lava flows from the nearby Hengill volcano. Now the researcher, Sandra Snaebjornsdottir, a doctoral student at the University of Iceland, was looking for…

Can Attention Deficit Drugs ‘Normalize’ a Child’s Brain?
Recent research that says that A.D.H.D. pills can “normalize” a child’s brain over time has drawn criticism.
