Intel Science and Engineering Fair 2009 Webcasts

Posted on May 17, 2009  Comments (3)

Tara Adiseshan, 14, of Charlottesville, Virginia; Li Boynton, 17, of Houston; and Olivia Schwob, 16, of Boston were selected from 1,563 young scientists from 56 countries, regions and territories for their commitment to innovation and science. Each received a $50,000 scholarship from the Intel Foundation.

In the webcast, Tara Adiseshan, talks about her project studying the evolutionary ties between nematodes (parasites) and sweat bees. She identified and classified the evolutionary relationships between sweat bees and the nematodes (microscopic worms) that live inside them. Tara was able to prove that because the two have such ecologically intimate relationships, they also have an evolutionary relationship. That is to say, if one species evolves, the other will follow.

Li Boynton developed a biosensor from bioluminescent bacteria (a living organism that gives off light) to detect the presence of contaminants in public water. Li’s biosensor is cheaper and easier to use than current biosensors, and she hopes it can be used in developing countries to reduce water toxicity.

Olivia Schwob isolated a gene that can be used to improve the intelligence of a worm. The results could help us better understand how humans learn and even prevent, treat and cure mental disabilities in the future.

In addition to the three $50,000 top winners, more than 500 Intel International Science and Engineering Fair participants received scholarships and prizes for their groundbreaking work. Intel awards included 19 “Best of Category” winners who each received a $5,000 Intel scholarship and a new laptop. In total, nearly $4 million is scholarships and awards were provided.

FreeWave’s Data Radios Bring Employee Bonuses

Posted on March 12, 2009  Comments (2)

It is easy with the existing economic news to think things are bleak everywhere. But even within the current climate companies find success. Founded in 1993, FreeWave Technologies is a world leader in the innovative design and manufacture of ISM Band radios and wireless data solutions. Their data-transmitting radios span the globe from the Middle East to Mount Everest; from the Amazon Rainforest to Antarctica to New York. They are used by defense contractors, oil and gas companies, city and county municipalities and industrial manufacturers.

FreeWave’s data radios are based on Frequency Hopping Spread Spectrum Technology. Spread Spectrum was originally created for the U.S. Navy during World War II to prevent the Germans from “jamming” American radio transmissions for radio-guided torpedoes. The technology was invented by Hedy Lamar, a famous movie star of the 1940’s. The original radios contained a roll of paper slotted like a player piano to cause channel switching. Hedy’s close friend, Inventor/Musician George Antheil, designed the first successful synchronization device that brought Hedy’s idea to fruition. In 1941, Hedy and George were granted a U.S. patent for the first “Secret Communications System.” The original system used merely 88 frequencies. Today, the switching is controlled in embedded firmware code that enables a radio to change frequencies hundreds of times per second and use more than 100 channels.

Engineering these radios is something the company takes quite seriously. And hiring the best talent is part of this philosophy. Every single employee considers it his/her job to ensure that customers receive top-notch service seven days a week. This extends all the way through the organization up to senior management. FreeWave is so dedicated to making its customers front and center that it provides 24-hour technical support – even rotating senior management to be on call at nights and on the weekends.

The privately held company is based in Boulder, Colorado, the company offers network design, pre-installation engineering services and manufactures its own radios (manufacturing them in Boulder).

FreeWave’s increase in revenues of 112 percent from 2003 to 2007. The company has paid this bonus every six months since the first one was paid in July 1995. Over the past year, FreeWave has invested in expanding its facility to accommodate more staff; growing its manufacturing space and capabilities; dedicating more resources and technology to its product development; increasing its customer and partner training; and, investing in marketing and sales.

Student Invents Solar-Powered Fridge for Developing Countries

21-year-old student/inventor/entrepreneur Emily Cummins has designed a brilliant portable solar-powered refrigerator that works based upon the principle of evaporation. Employing a combination of conduction and convection, the refrigerator requires no electricity and can be made from commonly available materials like cardboard, sand, and recycled metal.
…
Simply place perishable foods or temperature-sensitive medications in the solar refrigerator’s interior metal chamber and seal it. In-between the inner and outer chamber, organic material like sand, wool or soil is then saturated with water. As the sun warms the organic material, water evaporates, reducing the temperature of the inner chamber to a cool, 6 ºC [43 ºF] for days at a time!

After winning £5,000 from York Merchant Adventurers for her idea, Emily delayed going to college for a year to take her refrigerator to Africa for further development.
…
At 16 Emily won a regional Young Engineer for Britain Award for creating a toothpaste squeezer for people with arthritis, and the next year went on to win a Sustainable Design Award for a water-carrier made from wood and rubber tubing. In 2007 Emily was named the British Female Innovator of the Year, and last year was short-listed for Cosmopolitan’s 2008 Ultimate Women of the Year Competition.

Do Breast Tumors go Away on Their Own?

Posted on December 4, 2008  Comments (0)

Do Breast Tumors go Away on Their Own?

Authors of a new study hope to begin a debate challenging the conventional wisdom about early detection of breast cancer. In an article in today’s Archives of Internal Medicine, they ask: Do breast tumors ever go away on their own?

Researchers of this controversial article note that one type of cancer found through screening — a rare childhood tumor, called neuroblastoma — sometimes disappears. In the new article, researchers try to learn if the same phenomenon occurs with invasive breast cancers found with mammograms

The Natural History of Invasive Breast Cancers Detected by Screening Mammography

Conclusions: Because the cumulative incidence among controls never reached that of the screened group, it appears that some breast cancers detected by repeated mammographic screening would not persist to be detectable by a single mammogram at the end of 6 years. This raises the possibility that the natural course of some screen-detected invasive breast cancers is to spontaneously regress.

As with so much medical research the results are not completely clear. Studies need to be followed by more studies, which often lead to more studies. As long as progress is being made this is a perfectly reasonable course of scientific inquiry. And even if progress is not being made this can be perfectly reasonable – finding answers can be hard.

Where are the Senior Female Scientists

Posted on December 1, 2008  Comments (0)

Why Are Senior Female Scientists So Heavily Outnumbered by Men? by Anna Kushnir

There is some funny math in the world of academic science. Take my graduate school for example: My class was made up of eight people — seven women and one man, or 7 to 1. He was Snow White and we were the seven dwarves — each with a remarkably appropriate nickname. I was Grumpy, should you be curious to know.

Snow White and at least four of the dwarves have continued on to postdoctoral research jobs. That is a 4 to 3 ratio of women who went on to do a post-doc to those that chose alternate career paths.

Everything is adding up so far, right? Lots of women are around. Lots of science is being done. All is well. The next set of numbers is slightly puzzling, however. That is the ratio of female to male professors in our department, at a well-respected academic institution, is 48 to 7 men to women.
…
The proportion of female faculty in her department, 14 percent, is exactly equal to the overall average from the top fifty US chemistry departments.

From her blog: Lab Life: I thought I wanted to be “normal”

The majority of researchers, in my experience, think that stress level, pressure, and time commitments all drop by a factor of ten the moment you step outside of the chemical-smeared walls of a lab. I have come to realize that’s a misconception. It’s just not true. I think that whenever one wants a career instead of a job, time, stress, pressure, and worry are the price to pay.

If all I wanted was a job with a steady income, I am pretty sure I could get it. I would be well-rested and calm, but would I be happy? Would I be alright staying put where I am, with nothing pushing me to reach the next step or rise to the next level? I don’t think so.

I have heard the words ‘ambition’ and ‘drive’ described as derogatory, when applied to people. Unfortunately, I think those are apt words to describe me (in addition to ‘tired’ and ‘often occasionally cranky’). It was an important thing for me to understand about myself and come to terms with. It’s just who I am.

National Girls Collaborative Project for STEM

Posted on November 22, 2008  Comments (0)

The National Girls Collaborative Project for science, technology, engineering, and mathematics (STEM) collaborates with those seeking to increase the participation of girls in STEM feeder activities. The goal is to encourage girls to pursue careers in science, technology, engineering, and math.

Collaboration as a Means to Building Capacity: Results and Future Directions of the National Girls Collaborative Project:

The purpose of the NGCP is to extend the capacity, impact, and sustainability of
existing and evolving girl-serving STEM projects and programs. The NGCP is structured to bring organizations together to compare needs and resources, to share information, and to plan strategically to expand STEM–related opportunities for girls.
…
Although we are still refining it, the NGCP collaborative model has shown its effectiveness through increased collaboration and minigrant projects with sustained results. As we have described, the success to date of the NGCP in developing collaborations has been demonstrated via data from the collaboration rubric, mini-grant reports, and metrics that show how collaborative activities have increased over the duration of the NGCP projects. As NGCP expands over the next few years to provide regional collaboratives across the entire United States and Puerto Rico, we will continue our assessment of its impact and hope to be able to report its influence on building capacity to attract and retain girls in STEM.

I support programs encouraging STEM activities for girls – and boys. NSF data shows for 2005 shows women outnumbered men in undergraduate degree in science and engineering. For post-graduate degrees men still outnumbering women but that gap has been reducing and seems like it will continue to. And the representations in the workplace seem poised to continue to show a reducing number of men and increasing number of women. Engineering is an example of an area with far more men than women graduating – the imbalance is equivalent to the imbalance the other way for psychology.

Scientists With Lots of Monitors Onboard Ship

Posted on November 18, 2008  Comments (0)

photo of computer monitors onboard ship

Fun blog by Linds, a geophysicist, with fun name and tagline: PhD = Pretty huge Dork There’s no crying in grad school! I enjoy including some posts on scientists at work (and plan on trying to intentionally do more of that). The photo shows her office onboard ship – pretty impressive. I thought this monitor was cool.

The boat is a steel monster about 400 feet long. There’s three decks, with cabins, the galley and mess hall, a few different labs, a movie room, reading room and a weight room with white padded walls. It’s all very “Life Aquatic“, if you get the reference. [those that don't follow the link its a crazy movie - John]
…
We have been in transit for the past three days, getting our computers and systems up and running. We arrive at our first deployment spot tomorrow morning at 5:30 am. That is when we’ll put our first ocean bottom seismometer (OBS) down. The OBS itself is a sphere about 16 inches in diameter made of inch thick glass–these suckers are heavy! It’s vacuum sealed with the instrumentation inside and attached to an anchor. When we are done with the survey, the sphere is timed to detach from the anchor and it’ll float to the surface of the water. Our boat will pull up alongside it and we’ll scoop it out with a net and crane.
…
woke up today at 3am to get ready for my first watch. We definitely have the worst seas that we have had so far. We are definitely pitching and rolling out here! We deployed our first OBS at 5am and are doing about 1 instrument/hr for the next 24 hours.

Those snippets are from various posts on the blog. Another from earlier:

But there is recent good news: that lone female professor (who is an amazing researcher and is highly respected in the field, chairs many committees both nationally and within the department and was president of the Geological Society of America in the 90′s) has been named the new department chair. I think this move is important in encouraging talented women scientists to apply for positions within the department and shows dedication on the part of the higher-ups to highlighting ‘diversity’ as a priority.

Mentors prepare women for construction career

Now Cavitt and other women in the construction school, a part of ASU’s Ira A. Fulton School of Engineering, can give themselves another advantage: Learning from pioneering women who have already risen to leadership positions in the business.

The school recently established its Advancing Women in Construction program, a key part of which is a mentorship project. More than 70 women – and several men – in the construction industry in the greater Phoenix area have signed on to mentor female students and provide them an inside look at life in the industry.
…
plan to increase female enrollment from less than 15 percent of total enrollment to 30 percent – or about 200 female students – within five years.

Cavitt says her favorite things about the school’s construction management program are the opportunities to learn beyond the classroom, such as internships and building-project competitions between construction students at other universities. She expects the mentoring program to add significantly to the value of her college education. “I’m excited to learn about the real-world business of construction from women who have been successful at it for many years,” she says.

Beloit College: Girls and Women in Science

Posted on July 16, 2008  Comments (2)

Girls and Women in Science at Beloit College in Wisconsin:

sixth grade girls, along with their teachers and parents. This award winning conference encourages the exploration of science and mathematics by middle school girls through two days of experiments, activities, and interaction with science professionals. The girls, teachers, and parents will work with Beloit College faculty, students, and alumnae.

Girls getting into science

Eaton said the 24 girls participating will be able to take an active role in the laboratories. It’s critical the girls are encouraged and get the chance to increase their risk-taking abilities without boys.

The problem is, Eaton said, that sixth-grade girls’ interest in science starts dwindling and boys start becoming more dominant. “The boys take over the hands-on projects and the girls take notes,” Eaton said. “Boys will answer a question more authoritatively. Girls pose answers as a question. They are not as confident in their answers.”

To help foster activity among girls, the weekend conference also offers several workshops for parents and teachers. The workshops teach adults what they are doing to discourage girls and how they can learn to encourage them more.
