12:52 PM | Status update for Project MERCCURI
From @Jennomics (a co-PI on Project MERCCURI): Status update for Project MERCCURI: Our [surface] samples are being stored in a -80C freezer on the ISS. But, there is a problem with the equipment (plate reader) that will be used to run our “growth competition” experiment. The company that we are working with, NanoRacks is working hard to troubleshoot the problem. It isn’t clear now whether there is a problem with the inner workings of the equipment or the touchscreen […]

11:15 AM | Rae: Science Cheerleader, Chemist, and (awesome!) STEM communicator! (She’s also the managing editor of SciStarter!)
Here’s Raecca (Rae): Science Cheerleader, blogger, and SciStarter managing editor (among other things!) Hi, Rae! What got you into science? As a high school student, I enjoyed my math and science classes. If you gave me the option to solve an equation or read a novel, I would choose the equation every time. My senior-level science teachers were able to explain concepts in a clear manner, but they also infused humor whenever they could. My senior level math teachers were all...[ Read […]

8:06 PM | Generating primes in LaTeX
Inspired by a recent discussion on the wonders of , I started thinking about how easy it would be to generate prime numbers in . Well, unsurprisingly, it was presented as an example by Knuth using trial division in The TeXbook (download) in 1984: You can also do it by sieving; check out the examples […]

7:02 PM | How would scientists do on a public "science literacy" test -- and should we care? Stocklmayer & Bryant vs. NSF Indicators “Science literacy” scale part 2
So . . . this is the second post on the interesting paper Stocklmayer, S. M., & Bryant, C. Science and the Public—What should people know?, International Journal of Science Education, Part B, 2(1), 81-101 (2012).  Skip ahead to the bolded red text if you still vividly remember the first (as if it were posted “only yesterday”) or simply don’t care what it said & want to go straight to something quite interesting—the results […]

9:08 AM | Science Cheerleader Memorie: pursuing a Ph.D. while cheering for the WNBA.
I want to be an example of an intelligent and extremely hard-working cheerleader. I would also like to be a role model for young girls and other women, showing them that it is possible to have a successful career in science while at the same time following their other passions, such as cheerleading and dancing.

3:00 AM | Science Quiz – August 4, 2014
Every week, I create a science quiz for The Hindu newspaper’s In School product. It consists of 10 questions and only developments from the week preceding its day of publication (Monday). The answers are at the end. But this week’s quiz is a little different. 2014 marks the hundredth year after the start of World…

2:43 AM | Is There a Current or Imminent Global Food Shortage?
While environmental change may crimp food production, that has little to do with current food shortages, We're currently overproducing food crops and throwing them away on our habit of raising animal flesh in the cruelest and most efficient possible way, Globalization means that in the end, your food dollar competes with the food penny of the desperately poor. Your revealed preference in the marketplace is to eat large amounts of meat and dairy products and starve five poor people rather than […]

We are plagued by grumpy nostalgists — mystics on both wings who preach hostility to science & technology and yearn for the past. Our only route is forward. The answer to the problems generated by science is… more science. Open science, innovative, reciprocally critical & transparent, searching for positive sum games, able to detect potential errors.

9:17 PM | Stephanie: Military aerospace engineer and former college cheerleader, working on dual MSE + MBA degrees!
There seems to be this perception that engineers hole themselves up in their labs or cubicles, working on equations all day long without any interaction with other people. While this might be true for some engineers, the majority of us are constantly working with others in some way or another. You may have to collaborate on a design together, give a presentation about your work, or share your assessment of test results or reports.

1:46 PM | Asteroid scientists vent their concerns about ARM
At first glance, planetary scientists who study asteroids might seem to be obvious supporters of NASA’s Asteroid Redirect Mission (ARM) plans. It would, after all, redirect a small near Earth asteroid (NEA) into lunar orbit, where astronauts would visit it and return perhaps many kilograms of samples. In fact, though, many planetary scientists have expressed [...]

2:31 PM | Keeping up with the radioxenons
After the first of two nuclear weapon tests by North Korea, in 2006, a monitoring station in Yellowknife, Canada, caught a whiff of xenon-133, a radioactive isotope of xenon, in the atmosphere. It had been released by the blast and had traveled more than 7,500 km. Being a noble gas, it hadn’t reacted to anything on the way. The Yellowknife… Continue reading Keeping up with the radioxenons

4:13 PM | Edwards more optimistic about NASA authorization, less so about other legislation
While NASA administrator Charles Bolden expressed skepticism earlier this week that a NASA authorization bill would make it through Congress this year, a leading member of the House Science Committee said in a recent interview she is more optimistic about the bill’s prospects, but less so about two other pieces of space-related legislation. “I feel [...]

11:37 AM | New category: Exoplanets
Of late, telescopes like Kepler, Spitzer and ALMA are revealing new things about exoplanets as much as they’re exposing how clueless we are about their origins. Unlike in the search for life, where our only precedents are terrestrial, the search for and study of exoplanet systems is aided by Kepler’s revelation of hundreds of them,...Continue reading →

5:28 AM | Why do tilted/eccentric orbits form?
For all its mysteries, the Solar System is uniquely ideal in many ways. For one, while it has rocky inner planets and giant, gassy outer ones, astronomers have found that elsewhere, massive exoplanets often orbit close to their stars, as if they formed at a greater distance and then moved in. For another, the orbits of the...Continue reading →
