Inside a cell, tentacled vesicles shuttle cargo for sorting. DNA rearranges in the nucleus as stem cells differentiate into neurons. Neighboring neurons cling to one another through a web-like interface. And a new microscopy technique shows it all, in exquisite detail.

Volcanic activity did not play a direct role in the mass extinction event that killed the dinosaurs, according to an international, Yale-led team of researchers. It was all about the asteroid.

A new computational model shows how different patterns of crop rotation—planting different crops at different times in the same field—can impact long-term yield when the crops are threatened by plant pathogens. Maria Bargués-Ribera and Chaitanya Gokhale of the Max Planck Institute for Evolutionary Biology in Germany present the model in PLOS Computational Biology.

In a new study, U.S. and Austrian physicists have observed quantum entanglement among "billions of billions" of flowing electrons in a quantum critical material.

World leaders are currently updating the laws for international waters that apply to most of the world's ocean environment. This provides a unique opportunity, marine scientists argue this week, to introduce new techniques that allow protected zones to shift as species move under climate change.

Fish sticks may be a tasty option for dinner, but are they good for the planet?

Urban growth boundaries are created by governments in an effort to concentrate urban development—buildings, roads and the utilities that support them—within a defined area. These boundaries are intended to decrease negative impacts on people and the environment. However, according to a Penn State researcher, policies that aim to reduce urban sprawl may be increasing water pollution.

Tropical Cyclone Claudia was dissipating in the Southern Indian Ocean when NASA's Terra satellite captured a visible image of storm as it flew overhead in its orbit around the Earth.

Optical sensing in the mid to long infrared (5 microns [um]) is becoming of utmost importance in different fields since it is proving to be an excellent tool for environmental monitoring, gas sensing, thermal imaging as well as food quality control or the applications within the pharmaceutical industry, to name a few. The amount of information hidden within this very rich spectral window opens new...

Nanoscience can arrange minute molecular entities into nanometric patterns in an orderly manner using self-assembly protocols. Scientists at the Technical University of Munich (TUM) have functionalized a simple rod-like building block with hydroxamic acids at both ends. They form molecular networks that not only display the complexity and beauty of mono-component self-assembly on surfaces; they...

Experimental physicists have combined several measurements of quantum materials into one in their ongoing quest to learn more about manipulating and controlling the behavior of them for possible applications. They even coined a term for it— Magneto-elastoresistance, or MER.

Does the common stereotype for "organized crime" hold up for organizations of hackers? Research from Michigan State University is one of the first to identify common attributes of cybercrime networks, revealing how these groups function and work together to cause an estimated $445-600 billion of harm globally per year.

Researchers have developed a nondestructive and noninvasive optical technique that can determine the setting times for various types of cement paste, which is used to bind new and old concrete surfaces. The new method could aid in the development of optimized types of cement with less impact on the environment.

Although coming from a disadvantaged background, experiencing violence within the family, having a negative school environment or consuming violent media such as films and computer games have little or no direct influence on potential criminal behaviour among adolescents and young adults. These factors do often result in young people regarding violent acts as harmless and spending their time with...

Stable isotopes act like fingerprints or fibers in forensics, capturing details of where someone or something lived, what it ate or breathed, and how its environment changed over time.

The field of evolutionary biology has seen its share of spirited debates. But if there's one principle that virtually every expert in the field agrees on, it's that natural selection occurs at the level of the genome.

Scientists and Engineers have used surface-emitting semiconductor lasers in data communications, for sensing, in FaceID and within augmented reality glasses. In a new report, Yong-Ho Ra and a research team in the departments of Electrical and Computer Engineering, and Advanced Electronics and Photonics in Canada, Korea and the U.S., detailed the first achievement of an all-epitaxial, distributed...

Meteorologists at the U.S. Naval Research Laboratory plan to take a harder look in 2020 at a prime, yet difficult to model, component of the global water cycle known as atmospheric rivers.

Writing in Nature, researchers describe the first-time observation of 'self-organized criticality' in a controlled laboratory experiment. Complex systems exist in mathematics and physics, but also occur in nature and society. The concept of self-organized criticality claims that without external input, complex systems in non-equilibrium tend to develop into a critical state far away from a stable...

Researchers from North Carolina State University have found a very high prevalence of Bartonella bacteria in tumors and tissues—but not blood samples—taken from dogs with hemangiosarcoma, a cancer of the blood vessels. The work further supports the connection between persistent infection and some types of cancer and adds to the evidence that Bartonella can remain and thrive, undetected, within...

A highly sensitive, wearable gas sensor for environmental and human health monitoring may soon become commercially available, according to researchers at Penn State and Northeastern University.

Cell-to-cell contacts are necessary for the survival of human cells under protein-damaging conditions and stress. This was one of the conclusions made by a research team working under the leadership of Lea Sistonen, Professor in Cell and Molecular Biology at Åbo Akademi University. The results of their research were recently published in the Cell Reports journal.

While studies of the microbiomes (which comprises all the microorganisms, mainly bacteria and fungi) of the phyllosphere and the rhizosphere of plants are important, scientists at INRA believe more attention should be given to the microbiomes of crop residues.

According to received wisdom, local activism against the establishment of industrial plants follows a cycle, with its highest intensity a short time after mobilization. If a firm stands, activism is destined to fade away. New research published in the Strategic Management Journal suggests we should think again.
