4:49 PM | Amusing News Aliquots
Silly samplings from this week’s science news, compiled by Sophia Cai, Bethany Halford, and Jeff Huber. Stray baby elephant wanders into living room, gets a snack. The Newscripts gang would like a baby elephant, please. [io9] Scientists at England’s University of Leicester have run the numbers and determined that Noah’s ark could have held 70,000 […]

3:55 PM | You Got your Alchemy in my Art! You Got your Art in my Alchemy!
Plate IV in William Salmon’s Polygraphice (Roy G. Neville Historical Chemical Library, CHF) By Elisabeth Berry Drago Art and alchemy, science and painting. They’re kind of a delicious combination. And not as bizarre as it sounds, I promise. For a modern reader, William Salmon’s Polygraphice might seem like a strange jumble, a hodgepodge of unrelated things shoved into one overstuffed Hot Pocket of a book. Published in 1685, the Polygraphice is at first glance an […]

2:00 PM | It is a people business, after all
  Drs. Tom Baldwin and Miriam Ziegler have been a team for over four decades. As former trainees in the Baldwin/Ziegler lab, Carole Stivers, Zak Campbell, and I felt that it was an appropriate time to reflect on over forty years of science research and education by the Baldwin/Ziegler group. Tom and Miriam have been […]

12:31 PM | Tiny biomolecular tweezers studying force effect of cells
A new type of biomolecular tweezers could help researchers study how mechanical forces affect the biochemical activity of cells and proteins. The devices - too small to see without a microscope - use opposing magnetic and electrophoretic forces to precisely stretch the cells and molecules, holding them in position so that the activity of receptors and other biochemical activity can be studied.

10:18 AM | Gold Steps Up
Catalyst: A substance that increases the rate of a reaction without modifying the overall standard Gibbs energy change in the reaction (IUPAC Gold Book).Though most chemists agree on the above definition, there have always been two camps: "Academic" catalysis (1-20 mol%, 5-100 turnovers), and "Industrial" Catalysis (<0.01 mol%, >10,000 turnovers). As more researchers seek to translate early discoveries into efficient, "green" processes, the desire for robust organometallic […]

9:54 AM | Sicher Arbeiten mit Nanomaterialien
Die Deutsche Gesetzliche Unfallversicherung (DGUV) hat das neue Arbeitsschutz-Nano-Portal offiziell vorgestellt. Das Portal bietet aktuelle Informationen zur Arbeitssicherheit und neuartige, interaktive E-Learning Tools, die 'Nanoramen'.

8:41 AM | Interwoven solar cells turn T-shirt into a power textile
New solar cell technology allows your T-shirt to generate power from its interwoven solar cell wires. Researchers have developed a novel efficient wire-shaped polymer solar cell by incorporating a thin layer of titania nanoparticles between the photoactive material and electrode. An aligned carbon nanotube fiber enabled high flexibility and stability of the resulting polymer solar cell. These miniature polymer solar cell wires, when woven into textiles, can serve as a power source.

7:21 AM | Park Systems Introduces Automatic Defect Review for Semiconductor Wafers - An Astounding 1,000% Throughput Increase
Park Systems, a leading manufacturer of atomic force microscopy (AFM) products, introduces the Automatic Defect Review (ADR)AFM for 300mm bare wafers, a fully automated AFM solution that improves throughput of AFM defect review by up to 1,000%. The 300mm bare wafer ADR AFM is a new process for identifying defects designed specifically for the semiconductor market without the need of reference markers.

12:52 AM | Fukuyama, Round 2
An astute commenter has clued me in to the latest round of corrections coming from the Fukuyama research group (see 1, 2, 3, 4). Targets affected include lyconadins A-C, ecteinascidin 743, and mersicarpine, and publication dates range from 2010-2013. This time, they're in JACS which, to my knowledge, does not (yet) employ a full-time data analyst like Organic Letters does.The corrections read much the same as the last raft, released two months prior in Org. Lett., alleging […]

6:37 PM | Your morning troll: B.S. chemists need to be supervised, chemical engineers are teh awesome
Believe it or not, I have quite a few things to say, but I wanted to find time for this gem from a 2013 National Academies workshop on undergraduate chemistry education. (You can read it for free at the site, or you can download it, if you register.)There were lots of professors and representatives from industry at the conference. Here, John Kozarich (president of ActiveX Biosciences), Joel Shulman (professor at the University of Cincinnati), Shannon Bullard (HR director at DuPont), […]

6:22 PM | On being (sort of) scooped by both Carl Zimmer and Ed Yong
Being scooped once stings. Being scooped twice is a burn. But being scooped by two different prominent science writers makes your soul die. Unbeknownst to Carl Zimmer and Ed Yong, both of whom have had recent accounts of the parasitic jewel wasp, I too have been working on telling the story of the wasp’s intricate […]

5:14 PM | Don't gamble, use physics for LED lighting
Targeting a desired color for a white light-emitting diode is like spraying a savannah with buckshot in the hope of fortuitously downing a well-hidden deer. Scientists at the University of Twente and Philips have reached an understanding of the transport of light in white LEDs in physical terms.

1:46 PM | That Tiny Little Company Called ExxonMobil
Somehow by accident, I ran across this anti-petroleum website yesterday with the screaming headline of "Exxon to World: Drop Dead". It goes on to say:"ExxonMobil is saying it doesn’t believe governments will keep their internationally agreed commitments to limit climate change to safe levels. This should not come as any surprise. Of course they don’t believe governments are going to address climate change adequately — they are in fact betting billions on the failure of climate […]

Last Spring, the University of Minnesota department of chemical engineering and materials science held a lab safety video contest. Department chair Frank Bates thought it would be a nice way to motivate interest in the safety moments that the department holds before seminars, he says. The contest rules were simply that the videos had to […]
