UC San Diego researchers explain the mechanism of asexual reproduction in flatworms
Scientists have nailed the biomechanics of a centuries-long puzzle on how freshwater flatworms known as planarians reproduce. The asexual freshwater worms, notoriously difficult to study, tear themselves into two pieces that go on to form two new worms. Researchers are now able to predict where planarian fission occurs based on its anatomy as well as explain how the process happens using a relatively simple mechanical model.

DNA triggers shape-shifting in hydrogels, opening a new way to make 'soft robots'
Biochemical engineers at the Johns Hopkins University have used sequences of DNA molecules to induce shape-changing in water-based gels, demonstrating a new tactic to produce 'soft' robots and "smart" medical devices that do not rely on cumbersome wires, batteries or tethers.

VCU physicists discover a tri-anion particle with colossal stability
A team in the lab of Puru Jena, Ph.D., a distinguished professor in the Department of Physics in the College of Humanities and Sciences at Virginia Commonwealth University, has created the most stable tri-anion particle currently known to science. A tri-anion particle is a combination of atoms that contains three more electrons than protons. This discovery is novel because previously known tri-anion particles were unstable due to their numerical imbalance.

New manufacturing process for SiC power devices opens market to more competition
Researchers are rolling out a new manufacturing process and chip design for silicon carbide (SiC) power devices, which can be used to more efficiently regulate power in technologies that use electronics. The process -- called PRESiCE -- was developed to make it easier for companies to enter the SiC marketplace and develop new products.

The doubly magic nucleus of lead-208 -- it spins, though it shouldn't!
We imagine atomic nuclei to be more or less spherical, chaotic clusters of protons and neutrons. Experiments at the Argonne National Laboratory, inspired by physicists from the Institute of Nuclear Physics of the PAS, are verifying these ideas. Using an astronomical analogy we can say that the majority of nuclei are similar in outline to rocky moons or asteroids of different shapes, but nuclei of lead-208 can resemble planet surrounded by a dense atmosphere.

Molecular map shows how to disable dangerous bioweapon
Duke scientists recently mapped out the complex molecular circuitry that enables Francisella tularensis, the bacterium that causes tularemia, to become virulent. Tularemia is one of the top six bioterrorism agents, alongside anthrax, botulism, plague, smallpox and viral hemorrhagic fever. The new map, published in the journal Genes & Development, reveals a unique characteristic of the bacterium that could become the target of future drug development.

Arizona State University team shines new light on photosynthesis
A team of scientists from ASU's School of Molecular Sciences and Pennsylvania State University has taken us a step closer to unlocking the secrets of photosynthesis, and possibly to cleaner fuels. Their discovery was recently published online in Science and describes the structure of a reaction center (from a heliobacterium) which preserves the characteristics of the ancestral one, and so provides new insight into the evolution of photosynthesis.

The power of society: Scientists propose new area of study in energy generation
The growth of humanity is limited by our tools. Each era of human development, from caves to the Industrial Revolution to sending Curiosity to Mars, is marked by technological evolution. A collaborative team of scientists believe the next spurt of advancement is upon us, and it will be defined by energy production and consumption and the inherent human involvement. Their proposed methodology of establishing and investigating 'social energy' is published in IEEE/CAA Journal of Automatica Sinica.

Perovskite solar cells go single crystal
A recent work developed an innovative approach to self-grow single crystalline CH3NH3PbI3 directly on polycrystalline FTO/TiO2 substrate, with which n-i-p type of perovskite solar cells were fabricated. Highly efficient charge extractions occur at the interface between electron collecting TiO2 and photo-harvesting CH3NH3PbI3. The champion cell possesses a photovoltaic conversion efficiency of 8.78 percent, and there is still substantial room for further improvement, making it promising for the perovskite solar cell applications.

Slippery liquid surfaces confuse mussels
Mussels are one of the worst perpetrators of biofouling, or the unwanted accumulation of organisms on underwater structures. A team of scientists from the Wyss Institute and NTU, Singapore has demonstrated that a lubricant-infused surface effectively prevents mussels from sticking by masking the solid surface with a layer of liquid.

Researchers discover new class of chemical reaction
A new study led by Columbia Engineering professor Michael P. Burke has identified the significance of a new class of chemical reactions -- previously ignored -- involving three molecules that each participate in the breaking and forming of chemical bonds. The reaction of three different molecules is enabled by an 'ephemeral collision complex,' formed from the collision of two molecules, which lives long enough to collide with a third molecule.

New analysis casts doubt on predicted decrease in Oklahoma earthquakes
The disposal of wastewater from oil and gas production by injecting it deep into the ground has been linked to a dramatic increase in earthquake activity in Oklahoma since 2009. Injection rates have declined recently because of regulatory actions and market forces, but seismologists say that has not yet significantly reduced the risk of potentially damaging earthquakes.

Machine learning could be key to producing stronger, less corrosive metals
Researchers have studied grain boundaries for decades and gained some insight into the types of properties grain boundaries produce, but no one has been able to nail down a universal system to predict if a certain configuration of atoms at grain boundaries will make a material stronger or more pliable. An interdisciplinary team of BYU researchers have cracked the code by juicing a computer with an algorithm that allows it to learn the elusive 'why' behind the boundaries' qualities.
