The Results Are In

Well my first semester of Grad School is officially closed. Grades came out today, and for the first time in my 17 years of schooling, I managed to pull off a 4.0!

When my Dad retired he went back to school to get his Master’s degree and he graduated with a 4.0, so I made a bet with him that I could pull off grades like that too.

I’m glad I didn’t fail at our bet in my first semester, that would have been a disappointment. I still have three to go, but at least I’m starting off in great shape to have a GPA I can be proud of. Now I can turn my attention to getting ready for school to start again in mid-January.

Food Printing

Whenever I think about the food of the future, I think about Star Trek (I know, I know… I’m a nerd in a sorority girl shell) and how in the show their food is created by a machine that assembles the molecular composition of whatever food you order right in front of you. Needless to say like my hover car and robot maid, such things are still far in the future, but an interesting new way to prepare food is channeling this type of future food.

Food printing is a new technology that follows a recipe all on its own to come up with different meals, all you need to input are the ingredients. The technology is being developed by a team of researchers at Cornell University’s Computations Synthesis Lab as part of the Fab@home project. The 3D food printer only requires users to put in the ingredients and program the recipe, and the machine will do the rest. It can even be adjusted for picky eaters — making food moister or crispier, depending on the tastes of the consumer.

The technology would be especially beneficial for people won’t don’t either know how to cook or who don’t have the time to prepare big meals. It could also cut down on costs by limiting production waste during food preparation.

I’m pretty amazed by the creativity that researchers have shown in utilizing printing technology for new applications. In addition to 3D food assembly, printers can also be used for 3D cell culture. I wrote and article about 3D cell printers for BioTechniques last year, and I was amazed by the machines’ capabilities.

Eight Year Olds Under Peer Review

A group of elementary school children from the UK have achieved a world’s first by having the research they conducted for their school science project accepted into the peer reviewed journal Biology Letters. The group of 8-10 year olds was investigating the way bumblebees see colors and patterns.

The kids worked on their science project with Dr. Beau Lotto, a neuroscientists at University College London’s Institute of Opthamology. Under his supervision the kids discovered that bumblebees learn and remember based on color and pattern cues.

The kids’ paper successfully made it through peer review, and so was eligible for publication in Biology Letters. Unlike other papers featured in the journal, it doesn’t include citations to other relevant work because knowledge of the other scientific literature aren’t available to 8-10 year olds so they couldn’t have used them.

The kids’ work was published accompanied by a commentary by Laurence T. Maloney from New York University’s Center for Neural Science and Natalie Hempel de Ibarra from Exeter University’s Center for Research in Animal Behavior.

Solar Powered Surveillance

A solar airplane built in the UK recently set a new record for the longest unmanned autonomous vehicle (UAV) flight. The Zephyr, built by Qinetiq stayed aloft for 336 hours, 22 minutes, and eight seconds. The previous record was established in 2001 by the Global Hawk, built by Northrop Grumman. Zephyr bested the Hawk by eleven times, making it a big success.

The advantage that solar planes have is that they have the ability to hover over a location without having to orbit like a satellite or return to base for refueling like another plane. According to Qinetiq, solar airplanes are exciting because they have a variety of uses, including monitoring forrest fires, military communications, and tracking (locating pirates off the coast of Africa maybe?)

Even though this is unrelated to the concept of solar planes, I have to admit that what drew my attention to this article was the fact that the winning airplane was named Zephyr. I love that word, so for those who don’t know a Zephyr (noun) is 1 poetic/literary a soft gentle breeze. 2 historical a very light article of clothing. Its origin is late old english zefferus, denoting a personification of the west wind, via Latin from Greek zephuros (god of) the west wind.

It also happens to be in the title of one of my favorite songs. So here’s the Zephyr Song, by the Red Hot Chili Peppers.

Book Review: What Is The What?

While I was snowbound I read Dave Eggers’ What is the What. I’d read his book Zeitoun for J669 this past semester, and I’d heard a lot of good things about What is the What so I decided to check it out for myself. Ultimately I liked Zeitoun more, but I do think that What is the What is a great read, especially for someone who knows little about the civil war in the Sudan.

whatThe novel tells the story of Valentino Archak Deng’s life, (note: he is a real person) from the years before Sudan’s civil war reached the southern region where he lived – which were prosperous and happy, to his experiences after he fled his village and left his family (whom he believed were dead) to seek refuge in Ethiopia and Kenya, before being chosen to be resettled in America.

What is the What is a novel, because Eggers was forced to reconstruct scenes based on Deng’s memory of events that began when he was only 7 years old when he fled his home in the Sudan and became one of the Lost Boys. The book flips back and forth between Deng’s present life (at 27) and his childhood. Having to go back 20 years, Deng couldn’t remember all the details that would have been necessary to write the book as is. But don’t let the novel status fool you, What is the What is a true story. I have a lot of faith in Eggers as a writer, so I’m confident that the events described are as close as can be to the real events experienced by Deng.

I learned a lot about African history and the civil wars and conflicts that have plagued the continent in my J620 international communication class, but I still wouldn’t say I’m well informed. Reading What is the What solidified my opinion that the majority of conflicts are incredibly complex politically, economically, and socially, which few clear cut solutions.

The writing is clear cut and easy to understand, because Eggers does a really good job at explaining complex situations in a concise and comprehendible way. The sheer volume of death and violence witnessed by Deng and the other children of southern Sudan is rattling and reading this book has certainly made me want to find out more about what the current situation is in Sudan.
