University of Minnesota physicists play role in Large Hadron Collider research

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.

Bacterial 'food supplements' for small algae

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.

Ecosystems under threat from ocean acidification

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.

Safer nuclear reactors could result from Los Alamos research

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

Pollution from Asia circles globe at stratospheric heights

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.

Carnegie Mellon's kitchen chemistry makes science palatable

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.

ORNL Z-contrast microscope first to resolve, identify individual light atoms

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.

Scientists link climate change and Atlantic croaker fishery

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.

U of A-led experiment at CERN could rewrite laws of physics

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.

U of M expert says Earth's health reaching critical tipping point

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.

World's largest particle collider may unlock secrets of universe

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.

Improving predictions of climate change and its impacts

On March 22 at 11 a.m., EDT, the National Science Foundation (NSF) and the U.S. Departments of Energy and Agriculture hold a webcast announcing the launch of a joint research program to produce high-resolution models for predicting climate change and its resulting impacts.

20-year study yields precise model of tectonic-plate movements

MADISON — A new model of the Earth, 20 years in the making, describes a dynamic three-dimensional puzzle of planetary proportions.

Created by University of Wisconsin-Madison geophysicist Chuck DeMets and longtime collaborators Richard Gordon of Rice University and Donald Argus of NASA's Jet Propulsion Laboratory, the model offers a precise description of the relative movements of 25 interlocking tectonic plates that account for 97 percent of the Earth's surface.

Naval research laboratory takes a close look at unique diamonds

The song says that "diamonds are a girl's best friend," but scientists at the Naval Research Laboratory are finding that diamonds are a researcher's best friend too. NRL, which has been involved in pioneering work involving chemical vapor deposition of diamond and the use of diamond materials in advanced technologies relevant to the Department of Defense since 1987, has recently undertaken some new projects in diamond research.
