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.

Experiments call origin of Earth's iron into question
New research from The University of Texas at Austin reveals that the Earth's unique iron composition isn't linked to the formation of the planet's core, calling into question a prevailing theory about the events that shaped our planet during its earliest years.

Cedars-Sinai investigators identify human brain processes critical to short-term memory
Cedars-Sinai neuroscientists have uncovered processes involved in how the human brain creates and maintains short-term memories. This study is the first clear demonstration of precisely how human brain cells work to create and recall short-term memories.

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.

A new biological-behavioral-operational computer model could help policy makers choose the best intervention strategies to rapidly contain an infectious disease outbreak. The model is based on the dynamics of disease transmission across different environments and social settings, and provides critical information about how to mitigate infection, monitor risk and trace disease during a pandemic.

Is your big data messy? We're making an app for that
Vizier, software under development by a University at Buffalo-led research team, aims to proactively catch big data errors. The project, backed by a $2.7 million National Science Foundation grant, launched in January. Like Excel, Vizier will allow users to explore, clean, curate and visualize data in meaningful ways, as well as spot errors and offer solutions. But unlike spreadsheet software, Vizier is intended for much larger datasets; i.e., millions or billions of data points.
