Marine animal colony is a multi-jet swimming machine, scientists report
A colonial jellyfish-like species, Nanomia bijuga, employs a sophisticated, multi-jet propulsion system for swimming that is based on an elegant division of labor among young and old members of the colony. Reported this week in Nature Communications by scientists affiliated with the Marine Biological Laboratory, Woods Hole.

First global antineutrino emission map highlights Earth's energy budget
A team of geologists and physicists has generated the world's first global map of antineutrino emissions. The map, published online in the journal Nature Scientific Reports on Sept. 1, 2015, provides an important baseline image of the energy budget of Earth's interior and could help scientists monitor new and existing human-made sources of radiation.

New NGA global map advances R&D in geophysics and nonproliferation
A team of researchers led by scientists at the National Geospatial-Intelligence Agency published a new map Sept. 1 that characterizes the Earth's radioactivity and offers new and potential future applications for basic science research and nonproliferation efforts. The Antineutrino Global Map 2015, or AGM2015, is an unprecedented experimentally-informed model of the Earth's natural and manmade antineutrino flux.

Research in mice shows potential value of antidepressant in some stroke victims
Working with mice, researchers at Johns Hopkins have added to evidence that a commonly prescribed antidepressant called fluoxetine helps stroke victims improve movement and coordination, and possibly why.

Top university teacher influencing how high school physics will be taught
Meera Chandrasekhar, a professor of physics at the University of Missouri, received a $5 million multi-year grant from the NSF to address science instruction challenges. She developed a hands-on physics course for ninth graders designed to give them a better chance at being successful in higher-level science courses. The handheld tablet and computer-based curriculum application modules called 'Exploring Physics' were developed through this grant and have just become available for instructors and students.

Endangered animals can be identified by rate of genetic diversity loss
A Purdue University study presents a novel approach for identifying vertebrate populations at risk of extinction by estimating the rate of genetic diversity loss, a measurement that could help researchers and conservationists better identify and rank species that are threatened or endangered.

An engineered surface unsticks sticky water droplets
The leaves of the lotus flower and other natural surfaces that repel water and dirt, have been the model for many types of engineered liquid-repelling surfaces. As slippery as these surfaces are, however, tiny water droplets still stick to them. Now, Penn State researchers have developed nano/micro-textured, highly slippery surfaces able to outperform these naturally inspired coatings, particularly when the water is a vapor or tiny droplets.

Meet Pentecopterus, a new predator from the prehistoric seas
You don't name a sea creature after an ancient Greek warship unless it's built like a predator. That's certainly true of Pentecopterus, a giant sea scorpion with the features of a penteconter, one of the first Greek galley ships. Yale University researchers say Pentecopterus lived 467 million years ago and could grow to nearly six feet. It is the oldest described eurypterid -- a group of aquatic arthropods that are ancestors of modern spiders and ticks.

Columbia engineers develop new approach to modeling Amazon seasonal cycles
Columbia engineers have developed a new approach, opposite to climate models, to correct inaccuracies using a high-resolution atmospheric model that more precisely resolves clouds and convection and parameterizes the feedback between convection and atmospheric circulation. The new simulation strategy paves the way for better understanding of the water and carbon cycles in the Amazon, enabling researchers to learn more about the role of deforestation and climate change on the forest.

New synthetic tumor environments make cancer research more realistic
Tumors are notoriously difficult to study in their natural habitat -- body tissues -- but a new synthetic tissue environment may give cancer researchers the next-best look at tumor growth and behavior. University of Illinois researchers have developed a new technique to create a cell habitat of hydrogels which can realistically and quickly recreate microenvironments found across biology.

OU developing advanced radar for rapid updates and improved severe weather warnings
A team of engineers and meteorologists from the Advanced Radar Research Center located in the Radar Innovations Laboratory on the University of Oklahoma Research Campus will develop faster, more advanced imaging radar with a five-year, $3 million grant from the National Science Foundation. The C-band, mobile, polarimetric, imaging radar will provide simultaneous snapshots of a storm with unprecedented resolution and flexibility. The faster, more advanced imaging radar will lead to a better understanding of storms and provide improved severe weather warnings.

Intensity of desert storms may affect ocean phytoplankton
Scientists at MIT, Columbia University, and Florida State University have determined that once iron is deposited in the ocean, it has a very short residence time, spending only six months in surface waters before sinking into the deep ocean. This high turnover of iron signals that large seasonal changes in desert dust may have dramatic effects on surface phytoplankton that depend on iron.

A new technique to make drugs more soluble
Researchers from Harvard John A. Paulson School of Engineering and Applied Science have developed a new system that can produce stable, amorphous nanoparticles in large quantities that dissolve quickly. The system is so effective that it can produce amorphous nanoparticles from a wide range of materials, including for the first time, inorganic materials with a high propensity towards crystallization, such as table salt.

Political polarization on Twitter depends on the issue
Twitter offers a public platform for people to post and share all sorts of content, from the serious to the ridiculous. While people tend to share political information with those who have similar ideological preferences, new research from NYU's Social Media and Political Participation Lab demonstrates that Twitter is more than just an 'echo chamber.'
