Distinct stages of thinking revealed by brain activity patterns
Neuroimaging data can reveal the mental stages people go through as they are solving challenging math problems, according to a new study published in Psychological Science. By combining two analytical strategies, researchers were able to use functional MRI to identify patterns of brain activity that aligned with four distinct stages of problem solving.

World's most sensitive dark matter detector completes search
The Large Underground Xenon (LUX) dark matter experiment, which, with the help of Berkeley Lab researchers, operates beneath a mile of rock at the Sanford Underground Research Facility in the Black Hills of South Dakota, has completed its search for the missing matter of the universe. At a meeting in the UK, LUX scientific collaborators presented the results from the detector's final 20-month run.

Unconventional quasiparticles predicted in conventional crystals
An international team of researchers has predicted the existence of several previously unknown types of quantum particles in materials. The research represents the newest avenue in the physics of 'topological materials,' an area of science that has already fundamentally changed the way researchers see and interpret states of matter.

Yeast emerges as hidden third partner in lichen symbiosis
For nearly 150 years, lichens have been the model organisms of symbiosis. Now researchers have uncovered an unexpected third partner embedded in the lichen cortex or 'skin' -- yeast.

Accurate design of large icosahedral protein nanocages pushes bioengineering boundaries
Inspired by shells that protect virus genomes, researchers set out to design self-assembling, roomy protein structures capable of packaging and delivering cargo to cells. They have now engineered the largest, human-designed protein complexes to date confirmed by X-ray crystallography. The structures can self-assemble around other materials. This cargo-packaging capability may lead to creating a new generation of molecular machines that could deliver drugs or genetic therapies to cells, or carry tiny chemical reactors.

Come on baby, (re)light my fire
Many couples find that their sexual desire has dwindled over time. It's not unusual for partners who could not keep their hands off each to gradually lose interest. But new research indicates that there are ways that couples can sustain -- or relight -- their passion. 'Our research shows that partners who are responsive to each other outside the bedroom are able to maintain their sexual desire.'

Titanium + gold = new gold standard for artificial joints
Titanium is the leading material for artificial knee and hip joints because it's strong, wear-resistant and nontoxic, but an unexpected discovery by Rice University physicists shows that the gold standard for artificial joints can be improved with the addition of some actual gold.

Putting software on a diet
Concerns about battery life, heat creation, fan noise and overall high energy costs have driven the development of more energy-efficient computers and mobile devices over the past two decades. But the role of software in energy usage has been largely overlooked. A UD research team recently received a three-year, $516,000 grant from the National Science Foundation to support the development of more energy-efficient software.

Quantum drag
An University of Iowa physicist proposes that a current in one iron magnetic sheet creates a current in a separate sheet. The study's finding could be important in the emerging field of spintronics, which seeks to channel energy from spin waves generated by electrons to create smaller, more energy-efficient electronic devices.

3-D-printing lab instruments 1 block at a time
Building lab instruments for chemistry and biology experiments used to be an expensive, time consuming process only done by scientists with specialized training. A 3-D printed, Lego-like system of blocks designed by a UC Riverside team is changing that. In addition to real research applications, the system can also be used for STEM education, where students gain both an engineering experience by building the instruments and a science experience as they use them.

How water collector bees know when to quench hot hive's thirst
Thirst is a basic sensation that we must all react to, but how do water collector bees know when it's time to spring into action for a thirsty hive? Thomas Seeley and colleagues from Cornell University have discovered that water collector bees only begin searching for water when hive-mates begin begging for water; and when water is available and the hive is hot, water bottle bees store water for later use when the supply dwindles.

New nanoscale technologies could revolutionize microscopes, study of disease
Research completed through a collaboration with University of Missouri engineers, biologists, and chemists could transform how scientists study molecules and cells at sub-microscopic (nanoscale) levels. Shubra Gangopadhyay, an electrical and computer engineer and her team at MU recently published studies outlining a new, relatively inexpensive imaging platform that enables single molecule imaging. This patented method highlights Gangopadhyay's more than 30 years of nanoscale research that has proven invaluable in biological research and battling diseases.

Scientists watch water fleas take over new territory
Look into any nutrient-rich pond almost anywhere in the world and you will find Daphnia pulex, a tiny crustacean (also called a water flea) that is a source of food for fish and fascination for scientists. A new study, reported in the journal Molecular Ecology, offers insights into this creature's ability to disperse and its remarkable success in the wild.

For ancient deep-sea plankton, a long decline before extinction
A new study of nearly 22,000 fossils finds that ancient plankton communities began changing in important ways as much as 400,000 years before massive die-offs ensued during the first of Earth's five great extinctions. The research suggests that the effects of environmental degradation can be subtle until they reach a tipping point, at which dramatic declines in population begin.
