Small, useful things (links):Interesting, thought-provoking comments on LinkedIn by Boaz Vilozny.For the record, dear reader, I still hate the "endorse" button. Good stuff from the Baran Lab. Retraction Watch covers the UC-Boulder RNA/palladium nanoparticles retraction.Incidentally, may you live in times where people wish audits on scientists.Or may you not? The latest from Chad Jones' Chemical Dependence. Also, the latest from The Collapsed Wavefunction podcast on good portr...

 
[Review] Why do batteries fail?

Battery failure and gradual performance degradation (aging) are the result of complex interrelated phenomena that depend on battery chemistry, design, environment, and the actual operation conditions. The current available knowledge on these matters results from a vast combination of experimental and modeling approaches. We explore the state of the art with respect to materials as well as usage (temperature, charge/discharge rate, etc.) for lead-acid, nickel-cadmium, nickel–metal hydride, and...

 
C&EN: Medicinal chemist selling rotovap chilling device
Posted in Chemjobber

Credit: C&EN/George AdjabengAlso in this week's C&EN, a really great little story about a chemist who is selling a rotovap condenser chiller (story by Marc Reisch, registration required):[George] Adjabeng’s experience with rotovaps started at Ghana’s University of Cape Coast. After graduating in 2001, he received an M.S. degree in organic chemistry from Ontario’s Brock University and went to work for Roche in California. From 2004 to 2011, he worked for GlaxoSmithKline...

I challenge UC's call. Credit: PFTYou may have heard about this New York Times story by Amy Harmon about Jason Lieb, the University of Chicago molecular biology professor who resigned after the university administration made conclusions about his behavior at an off-campus retreat (this is a longer post, so the rest is after the jump.) ...The professor, Jason Lieb, 43, made unwelcome sexual advances to several female graduate students at an off-campus retreat of the molecular biosciences div...

 
Seriously? That Ancient Greek Statue Does Not Depict a Laptop

There's a new conspiracy theory out there, but instead of invoking big government or aliens, it questions whether there's a laptop carved into an ancient Greek statue. The theory, proposed by the anonymous YouTube user StillSpeakingOut, ventures that the ancient Oracle of Delphi may have foreseen the invention of laptops, and told people about it. "Just so we are clear, I'm not saying that this relief was depicting an ancient laptop computer," StillSpeakingOut said in the 100-second-long video....

CSB approves final report on West Fertilizer explosion

The U.S. Chemical Safety & Hazard Investigation Board (CSB) on Jan. 28 approved its final report on the 2013 ammonium nitrate fertilizer explosion in West, Texas, that killed fifteen people and injured hundreds of others. CSB found that key factors that led to the severity of the accident were: Poor hazard awareness Proximity of the facility to nearby homes and businesses Inadequate emergency planning Limited regulatory oversight Here’s CSB’s video about the incident: CSB issue...

 
Culture of compliance versus culture of safety

Quote fom a New York Times story about the collapse of a construction waste dump in China that killed at least 69 people. How many U.S. workplaces does it also describe? “It’s quite often that the goal is to get approval, rather than be truly in compliance with the spirit, whether it’s the environmental impact assessment or safety,” said Dali L. Yang, a professor at the University of Chicago who has studied China’s efforts to strengthen safety regulation. “The...

 
Better connected than Zuckerberg

Forget six degrees of separation. According to Facebook’s own research and data my “degree of separation” from others in the social networking site is just 3.09. Which means I am actually better connected than FB pres Mark Zuckerberg (3.17) although not as well connected as FB COO Sheryl Sandberg (2.97). Intriguingly, I have no direct mutual contacts with Zuck, but 3 mutual friends of Sheryl’s. The mean separation on Facebook is 3.57. My friend Ellie,...

[Editorial] Strength in members

A year ago on this page, I described some of the challenges that science faces in cultivating support from the society it serves. Stepping in as the new Chief Executive Officer of the American Association for the Advancement of Science (AAAS, the publisher of Science), my editorial asked, “Why science? Why AAAS?” My thoughts about the nature and service of science and the mission and goals of AAAS—the world's largest general science membership organization—have since been focusing on new...

Where infants sleep may affect how long they are breastfed

A new study indicates that mothers who frequently sleep, or bed-share, with their infants consistently breastfeed for longer than mothers who do not bed-share. Also, pregnant women who expressed a strong motivation to breastfeed were more likely to bed-share frequently once their baby was born. The findings, which come from a study of 678 women in a randomized breastfeeding trial who were recruited at mid-pregnancy, question whether recommendations to avoid bed-sharing due to concerns such as su...

 
Super Bowl Showdown: Would Broncos or Panthers Win a Real-Life Matchup?

While people are stocking up on Buffalo wings and potato chips in advance of the Super Bowl this Sunday, fans are split on who has the best chances of winning: the Denver Broncos or the Carolina Panthers. It turns out that the Super Bowl mascots would be a fairly even match out in the wild, too: While a panther is powerful and stealthy, broncos tend to live in herds, and they have strength in numbers, said Don Moore, a senior scientist at the Smithsonian's National Zoo, on assignment at the Asso...
