Why big brains are rare
Do big-brained creatures steal energy for them from other organs or eat more to supply this expensive tissue? New work in large-brained fish suggests skimping elsewhere is not enough to meet the energy demands of an extreme brain.

Scientists build bacteria-powered battery on single sheet of paper
Researchers at Binghamton University, State University of New York have created a bacteria-powered battery on a single sheet of paper that can power disposable electronics. The manufacturing technique reduces fabrication time and cost, and the design could revolutionize the use of bio-batteries as a power source in remote, dangerous and resource-limited areas.

Driverless platoons
MIT engineers have studied a simple vehicle-platooning scenario and determined the best ways to deploy vehicles in order to save fuel and minimize delays. Their analysis, presented this week at the International Workshop on the Algorithmic Foundations of Robotics, shows that relatively simple, straightforward schedules may be the optimal approach for saving fuel and minimizing delays for autonomous vehicle fleets. The findings may also apply to conventional long-distance trucking and even ride-sharing services.

Scientists crack genetic code determining leaf shape in cotton
Researchers know that the variation in leaf shapes can mean big differences in a farmer's bottom line. Now, a new discovery gives plant breeders key genetic information they need to develop crop varieties that make the most of these leaf-shape differences.

A fertilizer dearth foiled animal evolution for eons?
Earth was inhospitable to complex life for billions of years, practically suffocating evolution in a nearly oxygen-free environment. Then came a shift in phosphorus concentrations to ocean shallows, and after that, the evolution of complex life exploded.

UMN researchers provide molecular portraits of a new cancer drug target
Unprecedented images of cancer genome-mutating enzymes acting on DNA provide vital clues into how the enzymes work to promote tumor evolution and drive poor disease outcomes. These images, revealed by University of Minnesota researchers, provide the first ever high-resolution pictures of molecular complexes formed between DNA and the human APOBEC3A and APOBEC3B enzymes.

With eyes or noses? How young children use sensory cues to make social decisions
New research from the Monell Center reveals that children begin using olfactory information to help guide their responses to emotionally-expressive faces at about five years of age. The findings advance understanding of how children integrate different types of sensory information to direct their social behavior.

New prehistoric bird species discovered
A team of scientists at the University of Rochester has discovered a new species of bird in the Canadian Arctic. At approximately 90 million years old, the bird fossils are among the oldest avian records found in the northernmost latitude, and offer further evidence of an intense warming event during the late Cretaceous period.
