4:03 PM | Even in restored forests, extreme weather strongly influences wildfire’s impacts
We have hypothesized for many years that fire is a natural, even a necessary, part of stable forests/shrublands. But here we have a test that falsifies the hypothesis. Continue reading →

3:54 PM | Guest post: A comment on the 2014 Employment Outlook issue of C&EN
CJ here -- Frank wrote in with a comment about this year's Employment Outlook issue in C&EN, focusing on Susan Ainsworth's survey of industrial demand. It has been very lightly edited. It's the winter season and everyone's busy these days, trying to finish work up before the end of the year and also preparing for the holidays.  Even CJ's been busy this November and December.  While he highlighted a couple interesting articles in the Nov 3rd edition of C&EN, […]

3:47 PM | Carbon nanotubes enable new way of sound generation
Carbon nanotube assemblies enabled design of a hybrid thermo-electromagnetic sound transducer with unique sound generation features that are not available from conventional diaphragm and thermo-acoustic speakers. New work describes a hybrid thermo-electromagnetic sound transducer (TEMST) fabricated using highly porous multi-walled carbon nanotube sheet that was placed in the proximity of a permanent magnet. Upon electrical AC excitation, thermal response of the material is combined with […]

3:47 PM | Daily Pump Trap: 12/18/14 edition
A few of this past week's postings on C&EN Jobs: Pasadena, TX: I would love, love, love to see the applications that come in for this B.S. QC chemist position for Total's Bayport plant. They're asking for 5 years experience -- how much does that cost in the rather hot Texas chemistry job market? I'd love to know. Arlington, VA: This is such a weird B.S./M.S. policy position -- it sure seems like a government thing, but there's no obvious "security clearance needed" […]

3:45 PM | Pilot Project For Removal Of CO2 From Deep Waters
In the former mining area Herrerias in Andalusia, the deep waters of Pit Lake Guadiana show extremely high concentration of dissolved carbon dioxide (CO2).  Levels are so high that if it were to bubble up, human beings close-by would be jeopardized. To demonstrate a possible fix, scientists of the Spanish Institute of Geology and Mining, the University of the Basque Country (UPV/EHU, Bilbao) and the Helmholtz Centre for Environmental Research (UFZ) constructed a pilot plant for […]

3:43 PM | Cellular Hydrogen Peroxide - A New Twist On The Free Radical Antioxidant Relationship
Hydrogen peroxide (H2O2) is a strong oxidizer. You may know it as a wound disinfectant or as a bleaching agent for hair and teeth but it is also created naturally in our bodies, as part of our cellular oxidation. H2O2 belongs to a group of natural chemicals called reactive oxygen species (ROS) and when the process gets out of hand, too much oxidation can have a damaging effect on cells and their components. Unchecked free radicals, the most well-known ROS, are believed to play a role in […]

3:29 PM | The US Navy just tested a robotic shark
The U.S. Navy has finished testing an underwater drone that looks and acts like a big fish. The robotic GhostSwimmer can be used for a variety of tasks, and in recent tests the Navy used it to collect data on tides, currents, wakes, and weather conditions. A Massachusetts-based engineering firm called Boston Engineering designed and built the device, using the principles of "bio-mimicry"—designing machines that imitate the features and behavior of plants and animals.

3:21 PM | From naïve pluripotency to chimeras: a new ethical challenge?
This article by Insoo Hyun was first published in  Development. Also read the companion ethics article here.   In recent years, there has been much interest in the prospect of generating and using human stem cells that exhibit a state of naïve pluripotency. Such a pluripotent state might be functionally confirmed by assessing the chimeric contribution of these cells to non-human blastocysts. Furthermore, the […]

3:15 PM | Ethical considerations in chimera research
This article by Göran Hermerén was first published in  Development. Also read the companion ethics article  here.   The development of human pluripotent stem cells has opened up the possibility to analyse the function of human cells and tissues in animal hosts, thus generating chimeras. Although such lines of research have great potential for both basic and translational science, they […]
