Research Center Established to Explore the Least Understood and Strongest Force Behind Visible Matter

Science can explain only a small portion of the matter that makes up the universe, from the earth we walk on to the stars we see at night. Stony Brook University and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory (BNL) have established the Center for Frontiers of Nuclear Science to help scientists better understand the building blocks of visible matter. The new Center will push the frontiers of knowledge about quarks, gluons and their interactions that form protons, neutrons, and ultimately 99.9 percent of the mass of atoms - the bulk of the visible universe.

Cyborg Bacteria Outperform Plants When Turning Sunlight Into Useful Compounds (Video)

Photosynthesis provides energy for the vast majority of life on Earth. But chlorophyll, the green pigment that plants use to harvest sunlight, is relatively inefficient. To enable humans to capture more of the sun's energy than natural photosynthesis can, scientists have taught bacteria to cover themselves in tiny, highly efficient solar panels to produce useful compounds.

Scientists Create 'Diamond Rain' That Forms in the Interior of Icy Giant Planets

In an experiment designed to mimic the conditions deep inside the icy giant planets of our solar system, scientists were able to observe "diamond rain" for the first time as it formed in high-pressure conditions. Extremely high pressure squeezes hydrogen and carbon found in the interior of these planets to form solid diamonds that sink slowly down further into the interior.

Researchers Create Molecular Movie of Virus Preparing to Infect Healthy Cells

A research team has created for the first time a movie with nanoscale resolution of the three-dimensional changes a virus undergoes as it prepares to infect a healthy cell. The scientists analyzed thousands of individual snapshots from intense X-ray flashes, capturing the process in an experiment at the Department of Energy's SLAC National Accelerator Laboratory.

Nanotechnology Gives Green Energy a Green Color

Solar panels have tremendous potential to provide affordable renewable energy, but many people see traditional black and blue panels as an eyesore. Architects, homeowners and city planners may be more open to the technology if they could install colorful, efficient solar panels, and a new study, published this week in Applied Physics Letters, brings us one step closer. Researchers have developed a method for imprinting existing solar panels with silicon nanopatterns that scatter green light back toward an observer.

New 3-D Simulations Show How Galactic Centers Cool Their Jets

Scientists at Berkeley Lab and Purdue University developed new theories and 3-D simulations to explain what's at work in the mysterious jets of energy and matter beaming from the center of galaxies at nearly the speed of light.

"Getting to 80%" on Energy Cutbacks Cannot Occur Unless Behaviors Change

California's plan to cut energy consumption by 80 percent by 2050 cannot be achieved with current proposed policy changes because most solutions focus on changing technologies rather than changing behavior, a new UC Davis study suggests.

New Battery Material Goes with the Flow

Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory have engineered a new material to be used in redox flow batteries, which are particularly useful for storing electricity for the grid. The material consists of carefully structured molecules designed to be particularly electrochemically stable in order to prevent the battery from losing energy to unwanted reactions.
