Network model for tracking Twitter memes sheds light on information spreading in the brain
An international team of researchers from Indiana University and Switzerland is using data mapping methods created to track the spread of information on social networks to trace its dissemination across a surprisingly different system: the human brain.

Graphene heat-transfer riddle unraveled
Researchers have solved the long-standing conundrum of how the boundary between grains of graphene affects heat conductivity in thin films of the miracle substance -- bringing developers a step closer to being able to engineer films at a scale useful for cooling microelectronic devices and hundreds of other nano-tech applications.

Businesses don't always get what they want, but try to get what they need
Although most citizens tend to believe that big business owns Washington, D.C., a team of researchers suggests that business may have a less dominant and more complicated relationship with government than previously thought.

Scientists use molecular 'lock and key' for potential control of GMOs
UC Berkeley researchers have developed a way to put bacteria under a molecular lock and key as a way to contain its accidental spread. The method involves a series of genetic mutations that render the microbe inactive unless the right molecule is added to enable its viability.

New research shows Earth's core contains 90 percent of Earth's sulfur
So perhaps there is some truth in the old legends of the underworld reeking of brimstone (or sulfur, as it is now called)? New research confirms that the Earth's core does in fact contain vast amounts of sulfur, estimated to be about 10 times the amount of sulfur in the rest of the Earth, based on the most recent estimates (and for comparison, around 10 percent of the total mass of the moon).

Hematite 're-growth' smoothes rough edges for clean energy harvest

Do insect societies share brain power?
The cooperative or integrative aspects of insect colonies, such as information sharing among colony mates, can reduce the need for individual cognition in these societies, a new study suggests. Researchers compared social vs. solitary wasp species and found evidence that social brain evolution could dramatically different in insects than in vertebrates -- where complex societies require bigger brains.

Injured jellyfish seek to regain symmetry
Self-repair is extremely important for living things. Get a cut on your finger and your skin can make new cells to heal the wound; lose your tail -- if you are a particular kind of lizard -- and tissue regeneration may produce a new one. Now, Caltech researchers have discovered a previously unknown self-repair mechanism -- the reorganization of existing anatomy to regain symmetry -- in a certain species of jellyfish.

Small thunderstorms may add up to massive cyclones on Saturn
In a paper published today in the journal Nature Geoscience, atmospheric scientists at MIT propose a possible mechanism for Saturn's polar cyclones: over time, small, short-lived thunderstorms across the planet may build up angular momentum, or spin, within the atmosphere -- ultimately stirring up a massive and long-lasting vortex at the poles.

Penn researchers develop a new type of gecko-like gripper
Researchers at the University of Pennsylvania are developing a new kind of gripper, motivated by the ability of animals like the gecko to grip and release surfaces. Like the gecko, the gripper has 'tunable adhesion,' meaning that, despite having no moving parts, its effective stickiness can be tuned from strong to weak. Unlike the gecko and other artificial imitators that rely on structures with complex shapes, the Penn team's gripper uses a simpler, two-material structure that is easier to mass-produce.

Microbe mobilizes 'iron shield' to block arsenic uptake in rice
University of Delaware researchers have discovered a soil microbe that mobilizes an 'iron shield' to block the uptake of toxic arsenic in rice. The UD finding gives hope that a natural, low-cost solution -- a probiotic for rice plants -- may be in sight to protect this global food source from accumulating harmful levels of one of the deadliest poisons on the planet. Rice currently is a staple in the diet of more than half the world's population.

USF biologists: Biodiversity reduces human, wildlife diseases and crop pests
With infectious diseases increasing worldwide, the need to understand how and why disease outbreaks occur is becoming increasingly important. Looking for answers, a team of University of South Florida (USF) biologists and colleagues found broad evidence that supports the controversial 'dilution effect hypothesis,' which suggests that biodiversity limits outbreaks of disease among humans and wildlife.

World's thinnest lightbulb -- graphene gets bright!
Led by James Hone's group at Columbia Engineering, a team of scientists from Columbia, SNU, and KRISS demonstrated -- for the first time -- an on-chip visible light source using graphene, an atomically thin and perfectly crystalline form of carbon, as a filament. They attached small strips of graphene to metal electrodes, suspended the strips above the substrate, and passed a current through the filaments to cause them to heat up.

Underground ants can't take the heat
According to a new study from Drexel University, underground species of army ants are much less tolerant of high temperatures than their aboveground relatives -- and that difference in thermal tolerance could mean that many climate change models lack a key element of how animal physiology could affect responses to changing environments.

Stone tools from Jordan point to dawn of division of labor
Charcoal samples enable remarkably accurate estimates of 40,000 to 45,000 years ago for the earliest Upper Paleolithic stone tools in the Near East. The toolmakers appear to have achieved a division of labor that may have been part of an emerging pattern of more organized social structures.
