Barbara Liskov has won the Association for Computing Machinery’s A.M. Turing Award, one of the highest honors in science and engineering, for her pioneering work in the design of computer programming languages.

Liskov, the first U.S. woman to earn a PhD from a computer science department, was recognized for helping make software more reliable, consistent and resistant to errors and hacking. She is only the second woman to receive the honor, which carries a $250,000 purse and is often described as the “Nobel Prize in computing.”

“Computer science stands squarely at the center of MIT’s identity, and Institute Professor Barbara Liskov’s unparalleled contributions to the field represent an MIT ideal: groundbreaking research with profound benefits for humankind. We take enormous pride that she has received the Turing Award,” said MIT President Susan Hockfield.

“Barbara Liskov pioneered some of the most important advances in fundamental computer science,” said Provost L. Rafael Reif. “Her exceptional achievements have leapt from the halls of academia to transform daily life around the world. Every time you exchange e-mail with a friend, check your bank statement online or run a Google search, you are riding the momentum of her research.”

The Turing Award is given annually by the Association for Computing Machinery and is named for British mathematician Alan M. Turing, who helped the Allies crack the Nazi Enigma cipher during World War II.

Agricultural Irrigation with Salt Water

Irrigation system can grow crops with salt water

A British company has created an irrigation system that can grow crops using salt water. The dRHS (Dutyion Root Hydration System) irrigation system consists of a network of sub-surface pipes, which can be filled with almost any water, whether pure, brackish, salted or polluted. The system can even take most industrial waste-water and use it without the need for a purification process.

The pipes are made from a plastic that retains virtually all contaminants while letting clean water through to the plants’ roots.
…
The dRHS system, which has been in development for ten years, was initially trialled in the UK using tomato plants, and has since been tried out in the US. The next trials will take place in Chile, Libya, Tanzania, Mauritius and Spain. Tonkin says 20,000 metres of pipe are on their way to the Middle East, where it will be tested with water that’s more saline than sea water.
…
It has also won international recognition for its work, most recently at the international Water Technology Idol event in Switzerland, organised by Global Water Intelligence magazine and the International Desalination Association.

Christopher Gasson from Global Water Intelligence magazine says that the competition was a three-way tie last year but this year, the winner stood out. “The dRHS irrigation system addressed a bigger problem than the other technology that it was competing against,” he said. “Agriculture water is where 70 per cent of water goes. By 2025 two thirds of the world’s population will experience water shortages and so farming will be badly hit.

This is good news. I am still skeptical that this is as good as the article makes it sound. Just as simple as “flushing out the pipes.” But I am hopeful we will find desalination-type solutions. Clean water is a huge problem facing the world now, basically I just figure with enough engineers focused on finding workable solutions we will find several that have a huge impact. If not, we are in real trouble.

Brighton eighth-grader rewarded for her love for science

Thirteen-year-old Kate Yuhas, who plans to be an environmental engineer someday, has loved science since she was little.
…
Yuhas received an honorable mention certificate from the National Academy of Engineering’s EngineerGirl! Web site Imagine That! Engineering Innovation Essay Contest for her essay on a tanning booth that helps people produce vitamin D. “My whole life I’ve been interested in science,” Yuhas said. “I really like helping the environment and eating organic.”

“Kate has a talent for science and math, and she’s won medals at Science Olympiad,” said her mom, Johanna, who coaches the team. “Kate has always had science-themed parties. My husband and I are both engineers, and we talk a lot about science at home.”

The essay contest asked participants to consider one of three images on the EngineerGirl! site and to discuss its potential purposes and functions using engineering creativity.

Read Kate’s essay: The Cure to Vitamin D Deficiency

What can help prevent MS, high blood pressure, and several autoimmune diseases? The answer to that question would be Vitamin D, which you can get in three ways: food, supplements, and the sun. 70 percent of Americans lack adequate amounts of Vitamin D. The reason is that people just don’t get enough sun. That’s why my invention would be so helpful. It is a special tanning booth that only gives out the specific amount of UVB rays, the type of UV rays that is needed to produce Vitamin D, which you need.

The Engineer Girl website has done a smart thing and posted all the essays online. It is a simple act but one so often other organizations fail to do in similar circumstances.

The Million Dollar Programming Prize

One of the main areas of collaborative filtering we exploited is the nearest-neighbor approach. A movie’s “neighbors” in this context are other movies that tend to be scored most similarly when rated by the same viewer. For example, consider Saving Private Ryan (1998), a war movie directed by Steven Spielberg and starring Tom Hanks. Its neighbors may include other war movies, movies directed by Spielberg, or movies starring Tom Hanks. To predict a particular viewer’s rating, we would look for the nearest neighbors to Saving Private Ryan that the viewer had already seen and rated. For some viewers, it may be easy to find a full allotment of close neighbors; for many others, we may discover only a handful of neighboring movies.
…
A second area of collaborative-filtering research we pursued involves what are known as latent-factor models. These score both a given movie and a given viewer according to a set of factors, themselves inferred from patterns in the ratings given to all the movies by all the viewers [see illustration, “The Latent-Factor Approach“]. Factors for movies may measure comedy versus drama, action versus romance, and orientation to children versus orientation to adults. Because the factors are determined automatically by algorithms, they may correspond to hard-to-describe concepts such as quirkiness, or they may not be interpretable by humans at all.
…
The model may use 20 to 40 such factors to locate each movie and viewer in a multidimensional space. It then predicts a viewer’s rating of a movie according to the movie’s score on the dimensions that person cares about most. We can put these judgments in quantitative terms by taking the dot (or scalar) product of the locations of the viewer and the movie.
…
We found that most nearest-neighbor techniques work best on 50 or fewer neighbors, which means these methods can’t exploit all the information a viewer’s ratings may contain. Latent-factor models have the opposite weakness: They are bad at detecting strong associations among a few closely related films, such as The Lord of the Rings trilogy (2001–2003).

Because these two methods are complementary, we combined them, using many versions of each in what machine-learning experts call an ensemble approach. This allowed us to build systems that were simple and therefore easy to code and fast to run.

Intel Science and Engineering Fair 2009 Webcasts

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.

(video removed, so the embed code has been removed)

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. Li Boynton on What’s Great About Science:

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.

DoE: Minority Science and Engineering Improvement Program

The United States Department of Education’s Minority Science and Engineering Improvement Program (MSEIP) provides funds to schools to provide awards to students. 20 new awards (average value of $139,000) were awarded this year. That brings total funding this year to 71 awards (50 continue from previous years). Institutions recieving funds include: Clark Atlanta University, Rust College, New Mexico State University, Spelman College, Virginia State University and the College of Menominee Nation.

The program is designed to effect long-range improvement in science at predominantly minority and engineering education programs to increase the participation of underrepresented ethnic minorities, particularly minority women, into scientific and technological careers.

Wiley College, one of the new recipients, aims to increase the number of science majors, especially in the fields of biology and chemistry. A key feature of this grant is the creation of a high school science competition that will allow local and regional high school students to visit the campus and compete in a variety of scientific events.

This event will bring five area high schools together to compete in ten scientific events based on biology, chemistry, mathematics and physics. Individual first-place winners will be given scholarships to Wiley College. There will also be an overall grand champion awarded. This event will allow high school students to experience life at Wiley College and the possibilities of a career in science.

“This event not only gives students a financial reason to enroll at Wiley, but also allows them to become familiar with the campus and its faculty and students, said Dr. Shumate. “This grant also furthers a connection between Wiley and both the University of Texas at Dallas and the University of Arkansas, allowing current Wiley students to attend these schools in the summer for biomedical research.”

Trieste Science Prize Winners 2008

Beatriz Barbuy, an eminent Brazilian astrophysicist who has made a major contribution to the study of the evolution of the chemical composition of stars, and Roddam Narasimha, an internationally renowned Indian engineer and physicist whose work in fluid dynamics has increased our understanding of turbulence, have been awarded the 2008 Trieste Science Prize.
…
Barbuy’s research has shed light on the formation of the Milky Way through studies of its oldest components. She was the first to demonstrate that metal-poor stars in the galactic halo (the faint sphere surrounding the galactic disk) have an overabundance of oxygen, relative to iron. This indicates that the halo was chemically enriched by ‘supernova’ explosions of massive first-generation stars, which may have been 500 times the size of the sun.

Hydrogen and helium were the only elements produced in abundance during the formation of the first generation of stars. All of the heavier elements, which astronomers call ‘metals’, were subsequently produced by stars through nuclear fusion. At the end of a star’s life, some of these elements were recycled into the stellar medium, from which the next generation of stars (with greater ‘metallicity’) was born.
…
Narasimha’s contributions have extended to aircraft design, monsoon predictions and the prospects of using wind energy in rural India. He has also conducted important work on shock wave structure and turbulent shear flows. He is best known for his research on the transitions between laminar and turbulent flows. ‘Laminar flow’ is the smooth movement of fluid (for example, air or water) in parallel layers or paths (streamlines). Turbulence is the chaotic movement of fluid.

A search for the hidden order in chaos has been a fundamental motif of Narasimha’s work. His path-breaking research includes examinations of the ways in which chaos can arise from ordered motion and the structure and memory of fully turbulent flows.

The prize is awarded to outstanding scientists living and working in the developing world. Winners share a US$100,000 cash award.

William G. Hunter Award 2008: Ronald Does

The recipient of the 2008 William G. Hunter Award is Ronald Does. The Statistics Division of the American Society for Quality (ASQ) uses the attributes that characterize Bill Hunter’s (my father – John Hunter) career – consultant, educator for practitioners, communicator, and integrator of statistical thinking into other disciplines to decide the recipient. In his acceptance speech Ronald Does said:

The first advice I received from my new colleagues was to read the book by Box, Hunter and Hunter. The reason was clear. Because I was not familiar with industrial statistics I had to learn this from the authors who were really practicing statisticians. It took them years to write this landmark book.
…
For the past 15 years I have been the managing director of the Institute for Business and Industrial Statistics. This is a consultancy firm owned by the University of Amsterdam. The interaction between scientific research and the application of quality technology via our consultancy work is the core operating principle of the institute. This is reflected in the type of people that work for the institute, all of whom are young professionals having strong ambitions in both the academic world and in business and industry.
…
The kickoff conference attracted approximately 80 statisticians and statistical practitioners from all over Europe. ENBIS was officially founded in June 2001 as “an autonomous Society having as its objective the development and improvement of statistical methods, and their application, throughout Europe, all this in the widest sense of the words” Since the first meeting membership has grown to about 1300 from nearly all European countries.

The Nobel Prize in Chemistry 2008

The Nobel Prize in Chemistry 2008 is evenly shared by Osamu Shimomura, Boston University Medical School, USA; Martin Chalfie, Columbia University, New York, USA and Roger Y. Tsien, University of California, San Diego, USA for discovery and work with glowing green fluorescent protein.

The remarkable brightly glowing green fluorescent protein, GFP, was first observed in the beautiful jellyfish, Aequorea victoria in 1962. Since then, this protein has become one of the most important tools used in contemporary bioscience. With the aid of GFP, researchers have developed ways to watch processes that were previously invisible, such as the development of nerve cells in the brain or how cancer cells spread.

Tens of thousands of different proteins reside in a living organism, controlling important chemical processes in minute detail. If this protein machinery malfunctions, illness and disease often follow. That is why it has been imperative for bioscience to map the role of different proteins in the body.

This year’s Nobel Prize in Chemistry rewards the initial discovery of GFP and a series of important developments which have led to its use as a tagging tool in bioscience. By using DNA technology, researchers can now connect GFP to other interesting, but otherwise invisible, proteins. This glowing marker allows them to watch the movements, positions and interactions of the tagged proteins.

Researchers can also follow the fate of various cells with the help of GFP: nerve cell damage during Alzheimer’s disease or how insulin-producing beta cells are created in the pancreas of a growing embryo. In one spectacular experiment, researchers succeeded in tagging different nerve cells in the brain of a mouse with a kaleidoscope of colors.

Osamu Shimomura, a Japanese citizen, was born 1928 in Kyoto, Japan. He received his Ph.D. in organic chemistry 1960 from Nagoya University, Japan. first isolated GFP from the jellyfish Aequorea victoria, which drifts with the currents off the west coast of North America. He discovered that this protein glowed bright green under ultraviolet light.

Martin Chalfie demonstrated the value of GFP as a luminous genetic tag for various biological phenomena. In one of his first experiments, he coloured six individual cells in the transparent roundworm Caenorhabditis elegans with the aid of GFP.

Roger Y. Tsien contributed to our general understanding of how GFP fluoresces. He also extended the colour palette beyond green allowing researchers to give various proteins and cells different colours. This enables scientists to follow several different biological processes at the same time.
