SU physicists first to observe rare particles produced at the Large Hadron Collider at CERN

Shortly after experiments on the Large Hadron Collider (LHC) at the CERN laboratory near Geneva, Switzerland began yielding scientific data last fall, a group of scientists led by a Syracuse University physicist became the first to observe the decays of a rare particle that was present right after the Big Bang. By studying this particle, scientists hope to solve the mystery of why the universe evolved with more matter than antimatter.

Major advance in understanding how nanowires form

New insights into why and how nanowires take the form they do will have profound implications for the development of future electronic components. PhD student Peter Krogstrup from the Nano-Science Center at the University of Copenhagen is behind the sensational new theoretical model, which is developed in collaboration with researchers from CINAM-CNRS in Marseille.

Heavy metals open path to high temperature nanomagnets

How would you like to store all the films ever made on a device the size of an I-phone?

Magnets made of just a few metallic atoms could make it possible to build radically smaller storage devices and have also recently been proposed as components for spintronics devices. There's just one obstacle on the way. Nano-sized magnets have only been seen to work at temperatures a few hairs above absolute zero.

Chemists play important roles as advisers for science-based television shows, movies

ANAHEIM, March 27, 2011 — Do television shows like House, Breaking Bad, and Zula Patrol — major sources of information about science and technology for millions of people — try to get it right? Or do they play fast and loose with the facts, images, and nuances that forge public perceptions about science and help shape young people's career decisions?

Organizers pick key presentations at ACS 241st National Meeting & Exposition

ANAHEIM, March 27, 2011 — Organizers of the technical program at the American Chemical Society's 241st National Meeting & Exposition have identified these highlights from their own division or committee's presentations. The technical program is a journalistic treasure trove for spot news, features, story ideas, background, and sources for future coverage. It includes almost 9,400 papers that span scientific topics from astronomy to zoology.

Study predicts large regional changes in farmland area

CHAMPAIGN, Ill. — The effects of climate change and population growth on agricultural land area vary from region to region, according to a new study by University of Illinois researchers.

Regions with relative high latitudes – China, Russia and the U.S. – could see a significant increase in arable land in coming years, but Africa, Europe and India and South America could lose land area.

Civil and environmental engineering professor Ximing Cai and graduate student Xiao Zhang published their findings in the journal Environmental Research Letters.

Baylor, Texas A&M researchers find earliest people to inhabit the Americas

Baylor University geology researchers, along with scientists from Texas A&M University and around the country, have found the oldest archaeological evidence of human occupation in the Americas at a Central Texas archaeological site located about 40 miles northwest of Austin.

UBC researchers develop new model to predict the optical properties of nano-structures

University of British Columbia chemists have developed a new model to predict the optical properties of non-conducting ultra-fine particles.

The finding could help inform the design of tailored nano-structures, and be of utility in a wide range of fields, including the remote sensing of atmospheric pollutants and the study of cosmic dust formation.

Closing in on the pseudogap

Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have joined with researchers at Stanford University and the SLAC National Accelerator Laboratory to mount a three-pronged attack on one of the most obstinate puzzles in materials sciences: what is the pseudogap?

RIT researchers help map tsunami and earthquake damage in Japan

Japan needs maps. Not just any kind—detailed informational maps georegistered with latitude and longitude and annotated with simple, self-evident details: this bridge is out, this port is damaged, this farm field is scoured; this one is verdant.

Cutting carbon dioxide helps prevent drying

Washington, D.C.—Recent climate modeling has shown that reducing the concentration of carbon dioxide in the atmosphere would give the Earth a wetter climate in the short term. New research from Carnegie Global Ecology scientists Long Cao and Ken Caldeira offers a novel explanation for why climates are wetter when atmospheric carbon dioxide (CO2) concentrations are decreasing. Their findings, published online today by Geophysical Research Letters, show that cutting carbon dioxide concentrations could help prevent droughts caused by global warming.

Measurements of winter Arctic sea ice shows continuing ice loss, says CU-Boulder study

The 2011 Arctic sea ice extent maximum that marks the beginning of the melt season appears to be tied for the lowest ever measured by satellites, say scientists at the University of Colorado Boulder's National Snow and Ice Data Center.

UC research produces novel sensor with improved detection selectivity

A highly sensitive sensor that combines a variety of testing means (electrochemistry, spectroscopy and selective partitioning) into one device has been developed at the University of Cincinnati. It's already been tested in a variety of settings – including testing for components in nuclear waste.

Neutron analysis yields insight into bacteria for solar energy

OAK RIDGE, Tenn, March, 23, 2011 -- Structural studies of some of nature's most efficient light-harvesting systems are lighting the way for new generations of biologically inspired solar cell devices.

Researchers from Washington University in St. Louis and the Department of Energy's Oak Ridge National Laboratory used small-angle neutron scattering to analyze the structure of chlorosomes in green photosynthetic bacteria. Chlorosomes are efficient at collecting sunlight for conversion to energy, even in low-light and extreme environments.

Syracuse University chemist develops technique to use light to predict molecular crystal structures

A Syracuse University chemist has developed a way to use very low frequency light waves to study the weak forces (London dispersion forces) that hold molecules together in a crystal. This fundamental research could be applied to solve critical problems in drug research, manufacturing and quality control.
