New portable tool analyzes microbes in the environment
Imagine a device that could swiftly analyze microbes in oceans and other aquatic environments, revealing the health of these organisms - too tiny to be seen by the naked eye - and their response to threats to their ecosystems. Rutgers researchers have created just such a tool, a portable device that could be used to assess microbes, screen for antibiotic-resistant bacteria and analyze algae that live in coral reefs. Their work is published in the journal Scientific Reports.

Seismic biomarkers in Japan Trench fault zone reveal history of large earthquakes
Researchers used a novel technique to study the faults in the Japan Trench, the subduction zone where the magnitude 9.1 Tohoku-Oki earthquake struck in 2011. Their findings reveal a long history of large earthquakes in this fault zone, where they found multiple faults with evidence of more than 10 meters of slip during large earthquakes.

Discovery sheds new light on how cells move
Through experiments, UW-Madison researchers found that the force each cell applies to the surface beneath it -- in other words, traction -- is the dominant physical factor that controls cell shape and motion as cells travel as a group.

New species of Allosaurus discovered in Utah
A remarkable new species of meat-eating dinosaur, Allosaurus jimmadseni, was unveiled at the Natural History Museum of Utah. The huge carnivore inhabited the flood plains of western North America during the Late Jurassic Period, between 157-152 million years ago, making it the geologically oldest species of Allosaurus, predating the more well-known state fossil of Utah, Allosaurus fragilis.

Can I mix those chemicals? There's an app for that!
Improperly mixed chemicals cause a shocking number of fires, explosions, and injuries in laboratories, businesses, and homes each year. A new open source computer program called ChemStor developed by engineers at the University of California, Riverside, can prevent these dangerous situations by telling users if it is unsafe to mix certain chemicals.

Engineered capillaries model traffic in tiny blood vessels
3D microvessels have been created to observe how red blood cells transit ultra-small blood vessels. They squeeze single-file through microvessels to bring oxygen and nutrients. Red cells burdened with malaria stall, blocking the blood vessel. The platform is expected to have other uses in studies of how microvascular damage occurs in diabetes and sickle cell anemia. They might be further developed to supply blood circulation to organ repair patches or to 3D printed transplants.

Researchers expand microchip capability with new 3D inductor technology
Smaller is better when it comes to microchips, researchers said, and by using 3D components on a standardized 2D microchip manufacturing platform, developers can use up to 100 times less chip space. A team of engineers has boosted the performance of its previously developed 3D inductor technology by adding as much as three orders of magnitudes more induction to meet the performance demands of modern electronic devices.

Taking aim at gastric cancer
A novel drug, named 'FerriIridium,' can simultaneously help diagnose and treat gastric cancer. The initially weakly active precursor (prodrug), based on an iridium-containing compound, is selectively activated only after reaching the interior of a tumor cell. This is possible because of the higher amount of iron present there, report scientists in the journal Angewandte Chemie. Selective activation reduces undesired side effects.

New understanding of condensation could lead to better power plant condenser, de-icing materials
For decades, it's been understood that water repellency is needed for surfaces to shed condensation buildup - like the droplets of water that form in power plant condensers to reduce pressure. New research shows that the necessity of water repellency is unclear and that the slipperiness between the droplets and solid surface appears to be more critical to the clearing of condensation. This development has implications for the costs associated with power generation and technologies like de-icing surfaces for power lines and aircraft.

Wannier90 program becomes community code in major new release
Wannier90--a computer program for generating maximally-localized Wannier functions and using them in the computation of advanced electronic properties of materials--has become a community code with a wide base of contributors over the last few years. This has resulted in a major new release with novel features described in the paper Wannier90 as a community code: new features and applications, published in Journal of Physics: Condensed Matter.

Scientists discover how a curvy, stomach cancer-causing bacterium maintains its shape
A new study published in eLife shows how a common stomach bacterium is able to keep its corkscrew-like shape as it grows. Disrupting the shape could point the way for future, more-specialized antibiotics that prevent the bacterium from being harmful.

Surprise discovery shakes up our understanding of gene expression
A group of scientists has uncovered a previously unknown way that our genes are made into reality. Rather than directions going one-way from DNA to RNA to proteins, the latest study shows that RNA itself modulates how DNA is transcribed--using a chemical process that is increasingly apparent to be vital to biology. The discovery has significant implications for our understanding of human disease and drug design.

Life's Frankenstein beginnings
When the Earth was born, it was a mess. Meteors and lightning storms likely bombarded the planet's surface where nothing except lifeless chemicals could survive. How life formed in this chemical mayhem is a mystery billions of years old. Now, a new study offers evidence that the first building blocks may have matched their environment, starting out messier than previously thought.

Scientists identify gene that puts brakes on tissue growth
The planarian flatworm is a simple animal with a mighty ability: it can regenerate itself from nearly every imaginable injury, including decapitation. Scientists have studied these worms for decades to better understand fundamental principles of natural regeneration and repair. One mechanism that is yet unknown is how organisms like these control the proportional scaling of tissue during regeneration. Now, Northwestern University molecular biologists have identified the beginnings of a genetic signaling pathway that puts the brakes on the animal's tissue growth.
