Sustainability challenged as many renewable resources max out
The days of assuming natural resources can be swapped in and out to solve shortages -- corn for oil, soy for beef -- may be over. An international group of scientists demonstrate that many key resources have peaked in productivity, pointing to the sobering conclusion that 'renewable' is not synonymous with 'unlimited.'

New contaminants found in oil and gas wastewater
Duke University scientists have documented high levels of two potentially hazardous contaminants, ammonium and iodide, in wastewater being discharged into area streams and rivers from oil and gas operations in Pennsylvania. Levels of contamination were just as high in wastewater coming from conventional oil and gas wells as from hydraulically fractured shale gas wells.

Men want commitment when women are scarce
The sexual stereotype, in line with evolutionary theory, is that women want commitment and men want lots of flings. But a study of the Makushi people in Guyana shows the truth is more complex, with men more likely to seek long-term relationships when women are in short supply.

Robots learn to use kitchen tools by watching YouTube videos
Researchers at the University of Maryland Institute for Advanced Computer Studies have developed robotic systems that are able to teach themselves. Specifically, these robots are able to learn the intricate grasping and manipulation movements required for cooking by watching online cooking videos. The key breakthrough is that the robots can 'think' for themselves, determining the best combination of observed motions that will allow them to efficiently accomplish a given task.

Ancient fossils reveal rise in parasitic infections due to climate change
A paleobiologist from the University of Missouri has found indications of a greater risk of parasitic infection due to climate change in ancient mollusk fossils. His study of clams from the Holocene Epoch indicates that current sea level rise may mimic the same conditions that led to an upsurge in parasitic trematodes, or flatworms, he found from that time. He cautions that an outbreak in human infections could occur.

TSRI scientists discover possible new target for treating brain inflammation
A team led by scientists at The Scripps Research Institute has identified an enzyme that produces a class of inflammatory lipid molecules in the brain. Abnormally high levels of these molecules appear to cause a rare inherited neurodegenerative disorder, and that disorder now may be treatable if researchers can develop suitable drug candidates that inhibit this enzyme.

Solar cell polymers with multiplied electrical output
A team from Brookhaven Lab and Columbia University has paired up photovoltaic polymers that produce two units of electricity per unit of light instead of the usual one on a single molecular polymer chain. Having the two charges on the same molecule means the light-absorbing, energy-producing materials work efficiently when dissolved in liquids, which opens the way for a wide range of industrial scale manufacturing processes, including 'printing' solar-energy-producing material like ink.

From the bottom up: Manipulating nanoribbons at the molecular level
Researchers at Lawrence Berkeley National Laboratory and the University of California, Berkeley, have developed a new precision approach for synthesizing graphene nanoribbons from pre-designed molecular building blocks. Using this process the researchers have built nanoribbons that have enhanced properties -- such as position-dependent, tunable bandgaps -- that are potentially very useful for next-generation electronic circuitry.

People watching: Different brain pathways responsible for person, movement recognition
Researchers from University College London, Carnegie Mellon University and the University of California, San Diego have found that the ability to understand different movements, such as walking, skipping and jumping, engages different brain mechanisms from those that recognize who is initiating the action. Published in the Jan. 12 issue of the Proceedings of the National Academy of Sciences, the study illustrates for the first time how individuals with prosopagnosia, or face blindness, are still able to recognize other people's movements.

Infamous study of humanity's 'dark side' may actually show how to keep it at bay
In 1961, with memories of Holocaust atrocities and the prosecution of Nazi officials at Nuremburg still fresh, psychologist Stanley Milgram undertook a series of now infamous experiments on obedience and reprehensible behavior. But Milgram divided his subjects into just two categories: obedient or disobedient. After examining the experiences of more than 100 of Milgram's participants, Matthew Hollander, a graduate student in sociology at the University of Wisconsin-Madison, sees a great deal more nuance in their performances.

Mapping snake venom variety reveals unexpected evolutionary pattern
Venom from an eastern diamondback rattlesnake in the Everglades is distinct from the cocktail of toxins delivered by the same species in the Florida panhandle area, some 500 miles away. But no matter where you go in the Southeastern United States, the venom of the eastern coral snake is always the same. The results challenge common assumptions in venom evolution research, provide crucial information for rattlesnake conservation, and will help coral snake antivenom development.

Algae use same molecular machinery as land plants to respond to a plant hormone
Land-based plants -- including the fruits and vegetables in your kitchen -- produce and respond to hormones in order to survive. Scientists once believed that hormone signaling machinery only existed in these relatively complex plants. But new research from the University of Maryland shows that some types of freshwater algae can also detect ethylene gas -- the same stress hormone found in land plants -- and might use these signals to adapt to changing environmental conditions.

'Assassin' targets supernovae in our neighborhood of the universe
While many astronomical collaborations use powerful telescopes to target individual objects in the distant universe, a new project at The Ohio State University is doing something radically different: using small telescopes to study a growing portion of the nearby universe all at once. Since it officially launched in May 2014, the project has detected 89 bright supernovae and counting -- more than all other professional astronomical surveys combined.
