Deceptive behavior may (deceivingly) promote cooperation
Molecular 'hats' allow in vivo activation of disguised signaling peptides
When someone you know is wearing an unfamiliar hat, you might not recognize them. Georgia Institute of Technology researchers are using just such a disguise to sneak biomaterials containing peptide signaling ...
Apple patent focuses on tools for commuters
Moon's molten, churning core likely once generated a dynamo
When the Apollo astronauts returned to Earth, they brought with them some souvenirs: rocks, pebbles, and dust from the moon's surface. These lunar samples have since been analyzed for clues to the moon's ...
Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
Magnetic fields frozen into meteorite grains tell a shocking tale of solar system birth
The most accurate laboratory measurements yet made of magnetic fields trapped in grains within a primitive meteorite are providing important clues to how the early solar system evolved. The measurements point ...
Time, energy and storage capacity determine the measurement accuracy of the 'cell computer'
Researchers from FOM institute AMOLF have discovered what determines the accuracy with which cells can measure chemical concentrations. They described the results of their research in two publications: on ...
Fast, accurate new nanoparticle-based sensor system for screening cancer drugs
Traditional genomic, proteomic and other screening methods currently used to characterize drug mechanisms are time-consuming and require special equipment, but now researchers led by chemist Vincent Rotello ...
Cell biologists discover on-off switch for key stem cell gene
Consider the relationship between an air traffic controller and a pilot. The pilot gets the passengers to their destination, but the air traffic controller decides when the plane can take off and when it ...
Swarms of Pluto-size objects kick-up dust around adolescent Sun-like star
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) may have detected the dusty hallmarks of an entire family of Pluto-size objects swarming around an adolescent version of our own Sun.
Injectable 3D vaccines could fight cancer and infectious diseases
One of the reasons cancer is so deadly is that it can evade attack from the body's immune system, which allows tumors to flourish and spread. Scientists can try to induce the immune system, known as immunotherapy, ...
Study finds early warning signals of abrupt climate change
A new study by researchers at the University of Exeter has found early warning signals of a reorganisation of the Atlantic oceans' circulation which could have a profound impact on the global climate system.
Researchers convert sunlight to electricity with over 40 percent efficiency
UNSW Australia's solar researchers have converted over 40% of the sunlight hitting a solar system into electricity, the highest efficiency ever reported.
