In nanoscience, researchers are truly limited by the technology of their field, needing increasingly more advanced tools for studying, analyzing and manipulating objects and systems at the scale of individual molecules and atoms.

Scientists in Brazil are reporting for the first time that coffee beans contain proteins that can kill insects and might be developed into new insecticides for protecting food crops against destructive pests. Their study, which suggests a new use for one of the most important tropical crops in the world, appears in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication.

Common toads (Bufo bufo) can detect impending seismic activity and alter their behaviour from breeding to evacuation mode, suggests a new study in the Zoological Society of London's (ZSL) Journal of Zoology.

Researchers from The Open University reported that 96 per cent of male toads in a population abandoned their breeding site five days before the earthquake that struck L'Aquila in Italy in 2009. The breeding site was located 74 km from the earthquake's epicentre.

The Large Hadron Collider (LHC) at CERN in Geneva, Switzerland, launched a new era for particle physics today when the first particles collided at the record energy of seven trillion electron volts (TeV). Particle physicists around the world are celebrating the new achievement and what it will mean to physics research, including progress in the hunt for dark matter, new forces and new dimensions.

To boost their diet of mineral nutrients and sunlight, small algae also feast on bacteria in order to grow and fix carbon dioxide (CO2). Understanding more about the lifestyle of small algae - which are major players in CO2 fixation in the ocean - could help to improve ecological models of oceanic and global changes.

Professor Mike Zubkov from the National Oceanography Centre in Southampton presents his study on bacterioplankton consumption at the Society for General Microbiology's spring meeting in Edinburgh today.

Acidification of the oceans as a result of increasing levels of atmospheric carbon dioxide could have significant effects on marine ecosystems, according to Michael Maguire presenting at the Society for General Microbiology's spring meeting in Edinburgh this week.

Self-repairing materials within nuclear reactors may one day become a reality as a result of research by Los Alamos National Laboratory scientists.

BOULDER -- The economic growth across much of Asia comes with a troubling side effect: pollutants from the region are being wafted up to the stratosphere during monsoon season. The new finding, in a study led by scientists at the National Center for Atmospheric Research, provides additional evidence of the global nature of air pollution and its effects far above Earth's surface.

The international study is being published Thursday in Science Express. It was funded by the National Science Foundation, NCAR's sponsor, together with NASA and the Canadian Space Agency.

SAN FRANCISCO—Molecular gastronomy or molecular cuisine, the culinary movement that uses chemistry, is heating up kitchens worldwide. Carnegie Mellon University Chemist Subha Das is bringing the same techniques found in the world's leading restaurants, and seen on the popular television show Top Chef, to the classroom to teach students about the principles of chemistry.

OAK RIDGE, Tenn., March 25, 2010 -- Using the latest in aberration-corrected electron microscopy, researchers at the Department of Energy's Oak Ridge National Laboratory and their colleagues have obtained the first images that distinguish individual light atoms such as boron, carbon, nitrogen and oxygen.

The ORNL images were obtained with a Z-contrast scanning transmission electron microscope (STEM). Individual atoms of carbon, boron, nitrogen and oxygen--all of which have low atomic numbers--were resolved on a single-layer boron nitride sample.

A new climate-population model developed by NOAA scientists to study rising ocean temperatures and fishing rates on one East Coast fish population could also forecast the impact of climate change and fishing on other fisheries. The model is one of the first to directly link a specific fish stock with climate change.

An experiment led by a University of Alberta researcher, at the Large Hadron Collider (LHC) at CERN, could dramatically change our concepts of basic physics, revolutionize our understanding of the Universe and could eventually lead to technologies in future generations that right now only exist in science fiction.

U of A physics professor James Pinfold is leading an international team of physicists who will use ultra high energy proton collisions. The protons will move at very near the speed of light, in search for a hypothetical particle, called the magnetic monopole.

With climate change at the front and center of today's political debates, the other indicators of the Earth's environmental health are not always top of mind in the public conscience.

The Large Hadron Collider (LHC), the world's largest and highest-energy particle accelerator, could generate astonishing new insights into the Big Bang, the building blocks of the universe, the mysterious properties of dark matter and perhaps even extra dimensions in the universe.

Located at the CERN laboratory outside Geneva, the immense collider, which measures more than 16 miles in circumference, is expected to usher in a new era of particle physics research, enabling scientists to replicate conditions immediately after the Big Bang.
