Study finds plant enzyme function changes with location in cell

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists have long thought that individual enzymes have specific, single jobs dependent on their molecular shape. According to this premise, enzymes could only evolve to perform new functions by accumulating several shape-changing mutations, which can take thousands of generations. Now, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have discovered another factor that can change several plant enzymes' functions instantaneously: their location within the cell.

DOE scientists sample the skies

DOE/Brookhaven National Laboratory
Grant and Award Announcement

This summer, scientists from the U.S. Department of Energy's (DOE) Argonne National Laboratory (ANL), Brookhaven National Laboratory (BNL), and Pacific Northwest National Laboratory (PNNL) will take to the skies above Western Pennsylvania for one month to sample the air for aerosol pollutants and evaluate their effects on Earth's climate.

Why calcium improves a high-temperature superconductor

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists at Brookhaven National Laboratory have found evidence to prove why adding a small amount of calcium to a common high-temperature superconductor significantly increases the amount of electric current the material can carry. This research may be a first step toward developing commercial applications for high-temperature superconducting materials.

Future space scientists train at Brookhaven Lab

DOE/Brookhaven National Laboratory

As astronauts spend more time in space, scientists need to better understand the dangers space travelers face from deep-space radiation -- and how to best shield them against these risks. A new NASA Summer Student Program at the U.S. Department of Energy's Brookhaven National Laboratory will help provide a "pipeline" of researchers to tackle this challenge. The program begins June 1, 2004

Fluid 'stripes' may be essential for high-temperature superconductivity

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists have discovered evidence supporting a possible mechanism for high-temperature superconductivity that had previously appeared incompatible with certain experimental observations. The finding, which hinges paradoxically on what the scientists observed in a particular material that loses its superconductivity, is described in the June 3, 2004 issue of Nature.

Botulinum toxin structure offers clues for vaccines/treatments

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

By deciphering the near atomic-level structure of the catalytic domain of botulinum toxin type E -- one of seven neurotoxins that cause botulism, a disease that paralyzes victims by blocking nerve cells' ability to communicate -- scientists are one step closer to a potential vaccine or treatment.

New medical imaging technique first to use low-dose X-rays to reveal soft tissue

DOE/Brookhaven National Laboratory

X-rays from the National Synchrotron Light Source at Brookhaven Lab are being employed for the first time in diffraction enhanced imaging, a new, low-dose experimental technique to visualize not only bone, but also soft tissue.

Latest RHIC results make news headlines at Quark Matter 2004

DOE/Brookhaven National Laboratory

At the recent Quark Matter 2004 conference, new evidence was presented that gold-ion collisions at the Relativistic Heavy Ion Collider are producing an extremely dense form of matter -- which may, quite possibly, be the long-sought quark-gluon plasma.including the likelihood that RHIC's experiments have detected the existence of an "anti-pentaquark," an exotic type of particle containing five quarks, and may have uncovered signs of another dense form of matter called color glass condensate.

Brookhaven develops clean, sustainable energy alternatives

DOE/Brookhaven National Laboratory

Biofuel field testing, wind-energy design, battery-material development, natural-gas harvesting, clean hydrogen production -- these are several of the alternative-energy research initiatives now underway at Brookhaven. The goal is to transfer to industry technology that solves world-wide energy challenges in an innovative, economically feasible fashion.
