Sibling suns – made famous in the “Star Wars” scene where Luke Skywalker gazes toward a double sunset – and the planets around them may be more common than we’ve thought, and Cornell University astronomers are presenting new ideas on how to find them.

Space may not be the final frontier for Anna-Lisa Paul and Robert Ferl; they want to grow plants there. Because, who knows, we may one day try to live on Mars, and to survive, we’ll have to grow our own food.

New program helps bring scientists into political sphere.

Let's examine the chemistry behind soaking in the vino

In addition to sunblock, swimsuits and towels, hitting the beach could require hand sanitizer.

A simple, lower-cost new method for DNA profiling of human hairs developed by the University of Adelaide should improve opportunities to link criminals to serious crimes.

Berkeley Lab and USDA research could lead to new ways to fight beetle that devastates coffee crops worldwide.

Dark matter may find it tougher to hide in our universe.

Electronics giant TDK Corp. and the University of Alabama have signed a two-pronged research agreement to address challenges associated with the growing electric-energy movement and the miniaturization of electronic components.

High-fat feeding can cause impairments in the functioning of the mesolimbic dopamine system, says Stephanie Fulton of the University of Montreal and the CHUM Research Centre (CRCHUM.) This system is a critical brain pathway controlling motivation. Fulton's findings, published recently in Neuropsychopharmacology, may have great health implications.

North Carolina State University researchers have developed an effective and environmentally benign method to combat bacteria by engineering nanoscale particles that add the antimicrobial potency of silver to a core of lignin, a ubiquitous substance found in all plant cells. The findings introduce ideas for better, greener and safer nanotechnology and could lead to enhanced efficiency of antimicrobial products used in agriculture and personal care.

Blue LEDs can kill off pathogens most effectively in cold temperatures and acidic conditions.
