Even in the same animal, not all bites are the same. A new study finds that because the force in a muscle depends on how much it is stretched, an animal’s bite force depends on the size of what it is biting. The finding has direct implications for ecology and evolution.
PROVIDENCE, R.I. [Brown University] — Many animals prefer food — snails, nuts, etc. — that must be cracked and crushed. Scientists have measured the maximum force of their impressive bites before, but a new study introduces a significant subtlety: bite force depends not only on the size and strength of the eater, but also the size of the eatee. That insight has important implications in the lives of predators and prey. (more…)
One-third consider options other than the store for next purchase; Showrooming drives 50 percent of online sales
ARMONK, N.Y. – 15 Jan 2013: National Retail Federation Convention – A new IBM study of 26,000 global consumers released today at the 2013 National Retail Federation convention (#IBMNRF) found they are diversifying the way they shop for and acquire goods, becoming increasingly open to buying both online and in-store depending on their needs at time of purchase. While more than 80 percent of shoppers chose the store to make their last non-grocery purchase, only half are committed to returning there next time they buy.
IBM’s research finds that consumers are in a transitional state. According to the study, 35 percent are unsure whether they would next shop at a store or online. Nine percent are ready to commit to making future purchases online. Of all eight product categories tracked in the survey, the two most popular categories chosen by consumers for an online shift are consumer electronics and luxury items, including jewelry and designer apparel.

Cloud computing enhances control of “Internet of Things” in the home to help manage heating, lighting, security and more via multiple user interfaces including gestures and voice recognition
LAS VEGAS, CES – 08 Jan 2013: IBM, STMicroelectronics and Shaspa today announced a collaboration to tap cloud and mobile computing for manufacturers and service providers to provide innovative ways for consumers to manage and interact with their homes’ functions and entertainment systems using multiple user interfaces such as voice recognition and physical gestures for a smarter home.
A “smart home” brings networking functions together, creating a gateway that connects a television, computer or mobile device with smart meters, lights, appliances, plugs and sensors within the home as well as services from outside. Parks Associates forecasts that more than 8 billion devices will be connected on the home network by year-end 2015.[1](more…)
UD-Stanford team calculates maximum global energy potential from wind
Wind turbines could power half the world’s future energy demands with minimal environmental impact, according to new research published by University of Delaware and Stanford University scientists in the Proceedings of the National Academy of Sciences.
The researchers arrived at the determination by calculating the maximum theoretical potential of wind power worldwide, taking into account the effects that numerous wind turbines would have on surface temperatures, water vapor, atmospheric circulations and other climatic considerations.
“Wind power is very safe from the climate point of view,” said Cristina Archer, associate professor of geography and physical ocean science and engineering at UD. (more…)
The tuatara, an iconic New Zealand reptile, chews its food in a way unlike any other animal on the planet –challenging the widespread perception that complex chewing ability is closely linked to high metabolism.
Using a sophisticated computer model, scientists from UCL and the University of Hull demonstrate how the tuatara is able to slice its food like a “steak knife”. The tuatara’s complex chewing technique raises doubts about the supposed link between chewing and high metabolism in mammals.
The New Zealand tuatara (Sphenodon) is a lizard-like reptile that is the only survivor of a group that was globally widespread at the time of the dinosaurs. It lives on 35 islands scattered around the coast of New Zealand and was recently reintroduced to the mainland. Its diet consists of beetles, spiders, crickets, small lizards and, occasionally, sea birds. (more…)

ANN ARBOR, Mich
.— Twisting spires, concentric rings, and gracefully bending petals are a few of the new three-dimensional shapes that University of Michigan engineers can make from carbon nanotubes using a new manufacturing process.
The process is called “capillary forming,” and it takes advantage of capillary action, the phenomenon at work when liquids seem to defy gravity and spontaneously travel up a drinking straw.
The new miniature shapes have the potential to harness the exceptional mechanical, thermal, electrical, and chemical properties of carbon nanotubes in a scalable fashion, said A. John Hart, an assistant professor in the Department of Mechanical Engineering and in the School of Art & Design.
The 3D nanotube structures could enable countless new materials and microdevices, including probes that can interface with individual cells, novel microfluidic devices, and lightweight materials for aircraft and spacecraft. (more…)
