Sum of their parts: Researchers use math to foster environmental restoration
Resource management boundaries seldom align with environmental systems, which can lead to scale mismatch or spatial misalignments. Researchers Jesse Sayles of McGill University and Jacopo Baggio of Utah State University employ analytic modeling to counter this challenge and foster collaboration and efficient coordination of stakeholders' joint restoration efforts.

Widely accepted vision for agriculture may be inaccurate, misleading
'Food production must double by 2050 to feed the world's growing population.' This truism has been repeated so often in recent years that it has become widely accepted among academics, policymakers and farmers, but now researchers are challenging this assertion and suggesting a new vision for the future of agriculture.

Birds of a feather mob together
Dive bombing a much larger bird isn't just a courageous act by often smaller bird species to keep predators at bay. It also gives male birds the chance to show off their physical qualities in order to impress females. This is according to a study, led by Filipe Cunha, in Springer's journal Behavioral Ecology and Sociobiology on predator mobbing behavior of birds where potential prey approach and harass would-be predators such as owls.

First trace of differences between matter and 'ordinary' antimatter
The world around us is mainly constructed of baryons, particles composed of three quarks. Why are there no antibaryons, since just after the Big Bang, matter and antimatter came into being in exactly the same amounts? A lot points to the fact that after many decades of research, physicists are closer to the answer to this question. In the Large Hadron Collider beauty (LHCb) experiment the first trace of the differences between baryons and antibaryons has just been encountered.

Penn/Wistar study finds 'sweet spot' where tissue stiffness drives cancer's spread
Researchers from the University of Pennsylvania and The Wistar Institute have now found that physical forces exerted between cancer cells and the ECM are enough to drive a shape change necessary for metastasis. Those forces converge on an optimal stiffness that allows cancer cells to spread.

Penn engineers overcome a hurdle in growing a revolutionary optical metamaterial
Engineers in UPenn's School of Engineering and Applied Science produced an elusive diamond crystal structure that could revolutionize photonics. This put them on the path to achieving a material that is the 'holy grail of directed particle self-assembly.' Such materials could be used to make lenses, cameras and microscopes with better performance, or possibly even 'invisibility cloaks,' solid objects that would redirect all light rays around a central compartment, rendering objects there invisible.

Colorado River flows will keep shrinking as climate warms
Warming in the 21st century reduced Colorado River flows by at least 0.5 million acre-feet, about the amount of water used by 2 million people for one year, according to new research. Climate change models project increasing temperatures, but future precipitation projections have more uncertainty. The new report, the first to quantify the different effects of temperature and precipitation on recent Colorado River flow, shows as temperature keep increasing, Colorado River flows will keep declining.

Radiocarbon dating and DNA show ancient Puebloan leadership in the maternal line
Discovering who was a leader, or even if leaders existed, from the ruins of archaeological sites is difficult, but now a team of archaeologists and biological anthropologists, using a powerful combination of radiocarbon dating and ancient DNA, have shown that a matrilineal dynasty likely ruled Pueblo Bonito in New Mexico for more than 300 years.

Switched-on DNA
DNA, the stuff of life, may very well also pack quite the jolt for engineers trying to advance the development of tiny, low-cost electronic devices. Much like flipping your light switch at home -- only on a scale 1,000 times smaller than a human hair -- an ASU-led team has now developed the first controllable DNA switch to regulate the flow of electricity within a single, atomic-sized molecule.

It's more than just climate change
Accurately modeling climate change and interactive human factors -- including inequality, consumption, and population -- is essential for the effective science-based policies and measures needed to benefit and sustain current and future generations. A recent study presents extensive evidence of the need for a new paradigm of modeling that fully incorporates the feedbacks between Earth systems and human systems.
