This week's Sci-Light

This week underwater creatures have made headlines. Giant goldfish, measuring 1.5 feet long and weighing 4.2 pounds, were just recently discovered in the depths of Lake Tahoe. They were scooped up while researchers were searching for intrusive species in the lake. Environmental scientist from University of Nevada, Reno Sudeep Chandra revealed to LiveScience that there were about “…15 other goldfish… [which indicates] that they were schooling and spawning.” Chandra goes on to say that the goldfish could possibly affect Lake Tahoe’s ecosystem, and therefore cause danger to the native inhabitants.

The species was thought to have arrived in the lake by aquarium owners dumping their fish. Aquarium dumping is common and consequently damaging to native wildlife. The most common intruders consist of snails, tropical fish and seaweed. Lead author of a report on the state’s aquarium trade Sue Williams states, "Globally, the aquarium trade has contributed a third of the world's worst aquatic and invasive species.” Williams urges aquarium owners not to dump their fish or even flush them down the toilet. Instead you should call the pet shop or your state’s department of fish and wildlife to have them handled properly. For more information visit Yahoo! News.

In other news, Bottlenose dolphins may have a way to call to their loved ones when they’re away from each other. They mimic the loved one’s signature whistle, which acts as an identifier or a “name”. They don’t completely mimic the whistle, but add their own “tone of voice” which lets the loved one know who is calling them.

Stephanie King of the University of St. Andrews Sea Mammal Research Unit, with a team of colleagues, gathered acoustic samples from wild Bottlenose dolphins in the Sarasota Bay, Florida area and examined four captive male dolphins at the Seas Aquarium in Florida. They used the data to analyze and distinguish between the different whistles. For the full article go to Discovery News.

Networking Begins with You!

Perhaps your working right now on a personal statement for a summer opportunity or you're trying to imagine who should write a letter of recommendation (LOR) for you.  Most individuals think about references when then need them to write a letter, but a LOR begins long before you read the program description on the internet.

Confused?  I want to present this to you in a way you can finally get it.  When you request a letter from a professor, it should be in the context of a professional relationship with that professor.  How do you establish that?  Networking.

Oberlin College & Conservance Norman C. Craig '53 Lecture Hall

Most of the time students meet professors in a classroom.  They're in the back, slouched in a seat with a sweatshirt on and a pair of ripped jeans.  The professor, however, is in front of the room, but he can still see you yawning and playing on your phone.  Perhaps this is an early class and you just can't seem to drag yourself out of bed to get there.  The professor is in the classroom; she notices.  This is the beginning on an ineffective networking opportunity as well as a possible "F" in the class.

I recognize that many of you might be the student in the front of the room or somewhere in the middle who is coming on time, prepared and working hard on the course.  What I want you to know is that the professional relationships you build through school matter.  They can either help you gain further training like summer internships, on campus opportunities, jobs, contacts in the local area, and that amazing letter of recommendation that helps you transfer or get into a degree program.

So what should you do:
1.  Introduce yourself before or after class
2.  Be on time and engaged in class
3.  Ask questions
4.  Make an appointment or drop by during office hours
5.  Ask for help when needed in the subject matter
6.  Make your professional and career plans known to the professor
7.  Ask for advice and potential strategies to advance your knowledge and experience
8.  Say thank you
9.  Visit periodically during office hours
10.  Remain professionally engaged after the class with updates on your progress or questions

It's never to late to begin a professional network.  In fact, today is a great day to start.  Remember, networking begins with you!

The visually impaired can now partially see with the new FDA approved bionic eye called Argus II. Its function, as described by the Wall Street Journal, is to “…[send] electrical stimulation to the retina to induce vision in individuals afflicted with retinitis pigmentosa.” Retinitis pigmentosa causes retina damage, could eventually lead to blindness and affects about 100,000 Americans.

The Argus II consists of a retinal prosthesis implanted in the eye and a pair of glasses that work with the implant to enable the wearer to see in black and white and high contrasts. A video camera in the glasses captures an image, sends it to a small computer in the glasses, which turn it into digital data. That data goes to a receiver in the implant, triggers electrodes to stimulate the retina which helps the brain to process the information normally. The implant is now available in Europe but will be coming later this year to the U.S.

Doctor and medical professor at USC, Mark Humayun, aided in creating the device. He was quoted saying, “…many patients can use the Argus implant in their activities of daily living such as recognizing large letters, locating the position of objects, and more… the promise to the patients is real and we expect it only to improve over time.” Hopefully scientists will continue to experiment with the implant to produce better results as well as possibly a way for the visually impaired to fully see with a fresh pair of eyes.

If you were lost how would you find your way home? You could use breadcrumbs like Hansel and Gretel or just simply retrace your steps. What about using the Earth’s magnetic field? That happens to be how Sockeye salmon migrate their way back to their original birthplace to breed. Sockeye salmon breed in freshwater but live in the Pacific Ocean. After living for several years in the Pacific, they return to the freshwater rivers, where they were born, during the summer months.

A Researcher at Oregon State University Nathan Putman told BBC News, “… salmon remember the magnetic field where they enter the ocean, and come back to that same spot once they reach maturity.” One theory out of many that explains how salmon return to their birthplace is called natal homing, which BBC News explains as using chemical and geomagnetic cues to find their way back. Not only do they use an interesting homing mechanism, but the Pacific Salmon migration is said to be a very tough, survival of the fittest kind of journey.

It’s interesting how we use MapQuest and Google Maps to traverse around while marine animals essentially use their memories and the Earth’s forces to navigate through the ocean. Maybe one day we as humans will revert back to a more instinctual way of living.

'Wisdom' Speaks

Perhaps you've heard about the albatross--a sea bird with the longest wingspan of any bird on the planet today.  How long, you ask?  Try taller by feet than any basketball player.  To be precise, up to 11 feet across.

Wisdom is not only an albatross, but she is a mother at age 62.  And not for the first time, for Wisdom has hatched and raised between 30 and 35 chicks.  I can only imagine trying to complete her family tree with generations of offspring and their offspring and their offspring. 

When I saw this wonderful story, the teacher in me saw the wisdom of this animal.  Though the world keeps changing, the oceans rise, the winds blow, the ships cross the ocean, Wisdom keeps on her path.  In her life-time Wisdom has flown 2-3 million miles!  I suppose the message is simple and yet we need it.  Studying STEM can be discouraging and hard, but the payoff is found in persistence!

Without a doubt, this video will get your attention.  First, you may wonder what you're actually observing. Then you may struggle to understand how what you are seeing fits together.  When you get toward the end of the video and the scientists reveal the scope and scale, you will have the full picture.  Wow!  

This is a launching point for so many discussions--research, size and scale, icebergs, climate, oceans and so much more.  The physical world offers so much to see and learn from.  What is within your reach to learn just by being observant?  You don't have to be next to a glacier to be a scientist.  Have you looked at the trees and the size of their buds?  Where are the open spaces in your neighborhood?  What grows and lives there?  How does it change day-to-day?  

Earth gives little notice before major events.  They are observed by the observant, the scientists.  It could be seen by you!

College to Career

A results of a report, The Student Career Development Study, by Millennial Branding was published recently, admonishing students to be focused on careers while taking courses at a college or university.  The article mentions internships, social media such as Linked In, personal branding through business cards or professional blogging and finding mentors through on line networking groups.

A response written by Gene Marks for Forbes , challenges the notion that most business owners are on Linked In and reading blogs.  He proposes rather that students prepare for careers by doing well in their studies, including showing up to class.  Some schools are beginning to show attendance records on transcripts, according to the author, thus 'lifting the curtain' on students who test well but aren't reliable.  In addition, he admonishes students to be students and experience life at this stage.

These two articles present to me a question of focus.  When you are in school, where should your attention be directed?  The Forbes author makes a solid point by stressing the importance of doing your best and being diligent.  He even states that the student he hires needs to be "a smart enough person to learn the job."  My take home from this is, show up, work hard, do your best, seek help to do better, and while you're at it, take time to enjoy the experience.

The study by Millennial Branding has value as well by advocating that students think forward to their career.  My blend of this advise with the Forbes article would sound like this--take advantage of all the resources that you have on campus including your professors, network in person and on line, seek out connections that will help you grow and mature as a professional, be proactive about your life, think 21st Century.

For the student in the STEM fields this means find a way to experience science, technology, engineering and mathematics.  Maybe this is an internship or a volunteer job.  Perhaps you can join an professional organization that focuses on your field of interest.  You can't simply sit in a classroom and learn STEM; you must experience STEM.  How do you find these opportunities?  Re-read the paragraphs above.  Be proactive; find a way!
