3:55 PM | Watching Wetland Water Levels – Timelapse Photography
It’s timelapse photography time again…  I downloaded more photos from the cameras at our restored wetland in the Platte River Prairies a couple weeks ago, and have been looking through the images for stories.  One theme that stood out in … Continue reading →

3:55 PM | Serial Passage Of H5N2 In Mice
  # 8854   Influenza viruses are prolific, but sloppy, replicators.  They make millions of copies of themselves inside every host, but in the process, often make small transcription errors – amino acid substitutions – that can change the way the replicated virus acts.  Often, these changes are of little or no effect, or are even detrimental to the survival of the virus. Those that favor replication in the host, however, tend to carry on to produce […]

3:54 PM | Hot Weather Science
Too hot to bike? Pool too crowed?  Try some hot weather science! Just find a shady spot in the driveway, pull out the garden hose and you can experiment with siphons, water rockets, and fire-proof water balloons. Click on the experiment names to read directions and learn more about the science. Have fun!

3:41 PM | Footage of the 8th International Congress in Genetics! (Stockholm, 1948)
While searching for information regarding Åke Gustafsson, a plant breeder who practiced mutagenesis (and cited by Stebbins as providing experimental data for mutation studies), I stumbled upon an amazing video: footage from the 8th International Congress in Genetics held in Stockholm in 1948! Bengt Bengtsson and Anna Tunlid of Lund University digitized and annotated the video (the […]

3:40 PM | Economists set the course for a self-reflective debate
What makes a good economist? 6 Nobel Laureates and 8 young economists give answers. What is this world going to look like in 50 years – I’m worried and it ought to be a major concern of the profession. Robert J. Shiller Robert Shiller is one of six “Nobel Economists” featured in the two short […]

3:30 PM | Editorial mix-up leads to duplication, retraction of physics paper
A missed withdrawal request has ed to doubled up publication and a later retraction for Brazilian physicists, through no fault of their own. “Atmospheric Plasma Treatment of Carbon Fibers for Enhancement of Their Adhesion Properties” was presented at an Institute of Physics (IOP) conference in 2010. The proceedings weren’t published until May 2014. In the […]

3:27 PM | Time Passes at an Elephant’s Pace
Time passes at an elephant’s pace here at Mushara waterhole in the northeast corner of Etosha National Park, Namibia. The mornings are slow to materialize, a few solitary bulls drifting in like a lazy late morning gust from the northeast and then later from the southwest, each gliding through on non-overlapping paths. By early afternoon…

3:27 PM | What is a project house?
In an article by Alex Scott about Clariant and its R&D structure, an interesting paragraph (emphasis mine):The company now has eight R&D centers and 50 technical application labs worldwide. “We now have a very good infrastructure for trying to develop innovations,” Kottmann said. Clariant is also testing models for accelerating innovation. One such model, in trials for the past couple of years, is the so-called project house, which draws together chemists and commercial […]

3:22 PM | C&EN tackles chronic traumatic encephalopathy
Lauren Wolf looks at scientists trying to track the accumulation of tau (and other signs of CTE) in vivo: ...One question they’d like to answer is how much brain injury a person can handle before CTE sets in. With support from the Nevada Athletic Commission and local fight promoters, the group is gathering data by periodically testing its fighters and comparing them with a control group of age- and education-matched people who have never had head trauma. When the test subjects visit […]

3:13 PM | Skepticism about a published claim regarding income inequality and happiness
Frank de Libero writes: I read your Chance article (disproving that no one reads Chance!) re communicating about flawed psychological research. And I know from your other writings of your continuing good fight against misleading quantitative work. I think you and your students might be interested on my recent critique of a 2011 paper published […] The post Skepticism about a published claim regarding income inequality and happiness appeared first on Statistical Modeling, Causal […]

3:10 PM | 11 Strange and Bizzare Breeds of Chicken
Contrary to what many people think, not all chickens look more or less the same. Thanks to selective breeding, we have chickens that their differences extend way beyond a simple "This one is red", "This one's black" or a "This one is big".Today, we have all kinds of chickens. Some are great egg-layers. Others are perfect for producing meat and some are excellent in both of those fields. And of course, we have some that are simply weird-looking!So, let's check out some of weirdest looking […]

3:06 PM | This week's C&EN
From this week's issue: Wonderful quotes on committees: This letter on open workspaces takes a funny turn towards the end:...Teamwork and collaboration are important, but so is individual thought. The late science-fiction writer Robert Heinlein defined a committee as “a creature with three or more legs and no brain.” The National Aeronautics & Space Administration put it similarly: “None of us is as dumb as all of us.” James M. CastroHelena, Mont.Um, what's […]

3:03 PM | Go Forth and Science
Thank you. In April 2014, Slate announced its new paid membership program called Slate Plus. The Hive Overmind at Slate asked us writers to promote it and even had a contest: Whoever got the most people to sign up would get a $500 bonus. Seeing that I have a pretty big audience here and that I was asking that audience to pay for something, it didn’t feel right to keep that money if I won. So I announced that if I did win I’d give it all to Donors Choose, a non-profit group that […]

2:55 PM | More Than 20 Artificially Intelligent Space Probes Were Already Not Contained in the Frame of this Picture
You've probably heard the meme about "Michael Collins being the Only Human, Living or Dead, Not Contained in the Frame of this Picture"Here is another:"By the time this picture was taken, More Than 20 Artificially Intelligent Space Probes Were Already Not Contained in the Frame of this Picture"Some folks might argue that the space probes were not intelligent since they were commanded and controlled from Earth. This is not exactly true. There was at least one algorithm running on all these […]

2:48 PM | Reason Number Gazillion I Thank The FSM For The 2008 Election Result
That would be that Lindsay Graham, the Republican senator who is totally not pandering for re-election.  The idea that this guy would have had any possibility of a role at the center of the national security and or foreign policy apparatus in a McCain administration should send jolts of terror through anyone who doesn’t think […]

2:48 PM | Delayed Language More Nature Than Nurture
"She'll grow out of it," used to be a common phrase about raising kids, meaning it wasn't anything that was wrong physically or in upbringing, it is just the diversity of human existence. Some kids develop later. But in today's hyper-diagnosis culture, researchers have wanted to figure out if that old saying was true, or just wishful thinking. A  study of 473 sets of twins followed since birth has found that, compared to single-born children, 47 percent of 24-month-old identical twins had […]

By Jason Bittel Cold calculation: The Obama administration announced Friday that it will open the Eastern Seaboard for offshore drilling, and allow oil and gas companies to use sonic surveying cannons, a technology known to disrupt the communication systems of marine mammals, causing them to beach themselves. But hey, apparently that’s OK with the feds. “The U.S. Bureau of Ocean Energy Management acknowledged that thousands of sea creatures will […]

2:42 PM | Anti-distopía
El otro día voy a una librería. El librero me pregunta qué estoy leyendo. Le digo que “Makers” de Cory Doctorow, cuya ficción se sitúa en un futuro próximo. “Ah, ¿una distopía?”, me responde.No, no toda la CF futurista es una distopía y de hecho todas las distopías, hasta la fecha (las más famosas, no las he leído todas), están equivocadas. Al menos en un aspecto fundamental: la […]
