A circuit simulates an effect predicted by physicists but never actually observed

A group of physicists that includes scientists of the International School for Advanced Studies (SISSA) of Trieste have shown how to obtain a particular case of a physical effect – so far never observed in reality – whose studies have earned a Nobel Prize. The scientists have also observed the response of the material subject to such effect. These observations will provide precious indications to the experimental physicists in order to verify, in the future, their theory.

The identification of a single gene critical for yield of the oil palm, a crop that accounts for nearly half of world-wide edible vegetable oil, is reported along with the plant's genomic sequence in a set of papers published online July 24, 2013 ahead of print in Nature. The findings have implications for enhancing the future production and sustainability of palm oil, including a reduction in the pressure this productive tropical crop exerts on the footprint of wild rainforests. The work was authored by investigators from the Malaysian Palm Oil Board (MPOB) and Orion Genomics.

Kuala Lumpur, Malaysia, St. Louis, MO and Cold Spring Harbor, NY-- A multinational team of scientists has identified a single gene, called Shell, that regulates yield of the oil palm tree. The fruit and seeds of the oil palm are the source of nearly one-half of the supply of edible vegetable oil worldwide, and provide one of the most promising sources of biofuel.

Glacier retreat areas provide an excellent window into the evolution of microbial communities, an ideal opportunity for scientists to study how quickly soil biological functions become established and how ecosystems begin to form. Soils are not static in the landscape, but instead evolve with time under the influence of multiple environmental factors – understanding how these factors interact can lead to advancements in the science and management of soils.

A new biosensor, applied to the human skin like a temporary tattoo, can alert marathoners, competitive bikers and other "extreme" athletes that they're about to "bonk," or "hit the wall," scientists are reporting. The study, in ACS' journal Analytical Chemistry, describes the first human tests of the sensor, which also could help soldiers and others who engage in intense exercise — and their trainers — monitor stamina and fitness.

Philadelphia, PA, July 24, 2013 – To make the inherent bitterness of cocoa in chocolate ice cream more palatable, manufacturers add high levels of fat and sugar. Yet, bitterness is an integral part of the complex flavor of chocolate. In a new study published in the August issue of the Journal of Dairy Science®, investigators report that consumers who prefer dark chocolate in solid form tolerate twice the amount of bitter ingredients in chocolate ice cream than those who prefer milk chocolate.

A new method for producing electricity from carbon dioxide could be the start of a classic trash-to-treasure story for the troublesome greenhouse gas, scientists are reporting.

Cambridge, Mass. -- Computer graphics and digital video lag behind reality; despite advances, the best software and video cameras still cannot seem to get computer-generated images and digital film to look exactly the way our eyes expect them to.

But Hanspeter Pfister and Todd Zickler, computer science faculty at the Harvard School of Engineering and Applied Sciences (SEAS), are working to narrow the gap between 'virtual' and 'real' by asking a common question: how do we see what we see?

PITTSBURGH—It would be impossible to compute all of the ways a piece of cloth might shift, fold and drape over a moving human figure. But after six months of computation, researchers at Carnegie Mellon University and the University of California, Berkeley, are pretty sure they've simulated almost every important configuration of that cloth.

"I believe our approach generates the most beautiful and realistic cloth of any real-time technique," said Adrien Treuille, associate professor of computer science and robotics at Carnegie Mellon.

Climate data can help predict some crop failures several months before harvest, according to a new study from an international team, including a research scientist at NASA's Goddard Space Flight Center in Greenbelt, Md.

Alexandria, VA - In a field like earth science, adventures in the outdoors are commonplace. As this summer's field season comes to a close and the lanterns are extinguished one last time, EARTH Magazine explores the ritual of field camp as geoscientists' rite of passage from classroom learner to a workforce-ready scientist.

PITTSBURGH—The fingers of thousands of people who created sketches of Brad Pitt and Angelina Jolie on their iPhones can collectively guide and correct the drawing strokes of subsequent touchscreen users in an application created by researchers at Carnegie Mellon University and Microsoft Research.

"A wave is a deformation in the surface of a liquid that moves at a speed that is independent of that liquid," the researchers explain. For example: in the waves that are formed when a rock is thrown into a pond, the water remains still while the waves move away from the center at their own speed. "In our case, what occurs is actually the opposite: the water moves very rapidly (at several meters per second), but the wave moves at a speed of zero.

Considerable improvement in device performance of polymer-based optoelectronic devices is reported today by researchers from Ulsan National Institute of Science and Technology (UNIST), South Korea. The new plasmonic material, can be applied to both polymer light-emitting diodes (PLEDs) and polymer solar cells (PSCs), with world-record high performance, through a simple and cheap process.

The contrary demands of these devices mean that there are few metal nanoparticles that can enhance performance in PLEDs and PSCs at the same time.

BERKELEY — A new milestone by engineers at the University of California, Berkeley, can help robots become more touchy-feely, literally.

A research team led by Ali Javey, UC Berkeley associate professor of electrical engineering and computer sciences, has created the first user-interactive sensor network on flexible plastic. The new electronic skin, or e-skin, responds to touch by instantly lighting up. The more intense the pressure, the brighter the light it emits.
