Hillary Clinton once famously said, “It takes a village to raise a child.” It turns out that’s been true for centuries: New research by a University of Utah anthropologist explains how and why mothers in ancient societies formed cooperative groups to help raise their children.Karen Kramer, an associate professor of anthropology, published a study in the Journal of Human Evolution titled, “When Mothers Need Others: Life History Transitions Associated with the Evolution of Cooperative Breeding.”

El Salvador, Niger, and Pakistan are performing better in improving water and sanitation for their citizens than industrial giants like Russia and Brazil according to the new WaSH Performance Index developed by The Water Institute at the University of North Carolina at Chapel Hill’s Gillings School of Global Public Health. The new index to be released Friday, May 8 during a live webcast shows which countries are leaders in improving access to water and sanitation for their citizens.

Researchers from FOM Institute AMOLF have, for the first time ever, managed to make an image of the exterior structure of a protein aggregate that causes diseases like Alzheimer and type-2 diabetes. They discovered that the exterior surface of these aggregates are structured in very messy way – much unlike their neatly arranged interiors

(Phys.org)—A team of researchers with the European Academy of Bozen (EURAC) aka, the Institute for Mummies and the Iceman in Bolzano, Italy, has found examples of the oldest known samples of red blood cells. In their paper uploaded to the open access site, Journal of the Royal Society Interface, the team explains how they found the red blood cells and why they now believe the Iceman died very quickly.

Based on a comprehensive life cycle analysis comparing the environmental impacts and economic outcomes for managing manure and food waste produced on a dairy farm, researchers found that anaerobic co-digestion of the waste products had substantial cost, energy, and environmental benefits compared to digestion of manure but disposal of food waste in a landfill.

Researchers from North Carolina State University and China’s Suzhou Institute of Nano-Science and Nano-Biotics have developed an inexpensive technique called “microcombing” to align carbon nanotubes (CNTs), which can be used to create large, pure CNT films that are stronger than any previous such films. The technique also improves the electrical conductivity that makes these films attractive for use in electronic and aerospace applications.

A group of Cambridge computer scientists have set a new gold standard for openness and reproducibility in research by sharing the more than 200GB of data and 20,000 lines of code behind their latest results – an unprecedented degree of openness in a peer-reviewed publication. The researchers hope that this new gold standard will be adopted by other fields, increasing the reliability of research results, especially for work which is publicly funded.

Chatting on the red carpet with Bradley Cooper and Jennifer Lawrence; recording a country song with Clint Black; working a relief mission with Patricia Arquette; receiving a serenade from Michael Bolton on a Caribbean island. These are just some of the WOW! moments possible for everyday donors through a new online charity service that combines star power with digital marketing savvy to contribute millions to celebrity causes worldwide.

In proof-of-concept experiments, researchers at University of California, San Diego School of Medicine demonstrate the ability to tune medically relevant cell behaviors by manipulating a key hub in cell communication networks. The manipulation of this communication node, reported in this week’s issue of Proceedings of the National Academy of Sciences, makes it possible to reprogram large parts of a cell’s signaling network instead of targeting only a single receptor or cell signaling pathway.

New York City Mayor Bill de Blasio’s claim during a recent blizzard that food delivery bikes were not emergency vehicles caused a small disruption in the City’s normally fast, abundant and inexpensive access to nearly any type of food from around the world. For major food companies that ensure this access, blizzards here or droughts in California increase costs, affect supply and demand, and change trade patterns.
