Here are some of the NSF-supported discoveries and activities highlighted in 2006.
Credit and Larger Version

January 9, 2007

From the far reaches of space to inner workings of molecules, discoveries resulting from National Science Foundation (NSF) investments in research and education enable the United States to remain at the forefront of science and engineering knowledge and also enhance the nation's economic strength in the face of global competition. Here are some of the NSF-supported activities highlighted in 2006. Also, listed separately are the stories that visitors to our Web site selected most often.

Discovery of a Planet Close to Earth's Mass Shows the Promise of Gravitational Microlensing
Using a relatively new technique that can spot planets one-tenth the mass of the Earth, researchers announced the discovery of a potentially rocky, icy body--OGLE-2005-BLG-390Lb--that may be the smallest planet yet found orbiting a star outside our solar system. The discovery suggests gravitational microlensing may be exceptionally useful in finding distant planets with traits that could support life. Discover magazine included the discovery in its list of the Top 100 science stories for 2006.

Scientists Issue Unprecedented Forecast of Next Sunspot Cycle
The next sunspot cycle will be 30 to 50 percent stronger than the last one, and begin as much as a year late, according to a breakthrough forecast using a computer model of solar dynamics developed by scientists at the National Center for Atmospheric Research in Boulder, Colo. The researchers, supported by NSF and NASA, expect that predicting the Sun's cycles years in advance will lead to more accurate plans to anticipate solar storms, which can slow satellite orbits, disrupt communications and bring down power systems.

Single-molecule Diode Raises Possibility of New Era of Miniaturization
Using the power of modern computing combined with innovative theoretical tools, an international team of researchers has determined how a one-way electrical valve, or diode, made of only a single molecule does its job. Created by a research team at the University of Chicago, the diode is merely a few tens of atoms in size and 1,000 times smaller than a conventional transistor. Theorists from the University of South Florida and the Russian Academy of Sciences have explained the principles that make the device work. The technology may allow computer designers to sustain "Moore's Law"--a prediction made by Intel co-founder Gordon Moore in 1965--which suggested technological advances will allow a doubling every 18 months in the number of transistors that can fit on a computer chip.

This Fish Was Made for Walking?
Working in rocks more than 375 million years old, NSF-supported paleontologists unearthed a remarkable new fossil species that could fill in the evolutionary gap between fish and early limbed animals. The new species, named Tiktaalik, has a skull, neck, ribs and parts of a fin that resemble the earliest limbed animals, called tetrapods. But Tiktaalik also has fins and scales like a fish. Scientists collected the fossils during four summer explorations on Ellesmere Island in Canada's Nunavut Territory, far above the Arctic Circle. The journal Science has named the discovery a runner-up for Breakthrough of the Year, and Scientific American called it one of the most important science stories of 2006.

Waterproof Superglue May Be Strongest in Nature
The glue one species of water-loving bacteria uses to grip its surroundings may be the strongest natural adhesive known to science. Researchers at Indiana University in Bloomington and Brown University in Providence, R.I., studied how much force they needed to tug the tiny, stalked Caulobacter crescentus off a glass plate. The researchers reported that the bacteria grip with a force of 70 newtons per square millimeter--roughly 5 tons per square inch; equivalent to the downward force exerted by three cars balancing on a spot the size of a quarter.

Redesigning High-School Advanced Placement Work in Math and Science
Researchers for the College Board are using a $1.8 million grant from NSF to redesign Advanced Placement (AP) program courses in biology, chemistry, physics and environmental science. Studies have shown that, in general, U.S. high school students continue to slip further behind other nations in their ability to apply scientific concepts and skills, and also that the percentage of American undergraduates earning degrees in science and engineering is far below that of other competitive nations. AP students are an important exception. Research indicates that AP math and science courses enable their students to achieve a level of proficiency that exceeds that of students from all other nations.

Ecosystems With Many Plants Produce More and Survive Threats Better
Based on more than 12 years of work at the Cedar Creek Long-Term Ecological Research site, one of 26 such NSF sites, researchers found that ecosystems containing many different plant species are more productive and better able to withstand and recover from climate extremes, pests and disease over long periods than ecosystems containing only one species. The study was the first experiment to gather enough data--over a sufficient time and in a controlled environment--to confirm a 50-year scientific debate about whether biodiversity stabilizes ecosystems.

Understanding and Preventing Levee Failures
Following an eight-month study of the New Orleans levee system and its performance during and after Hurricane Katrina, a team of researchers led by Raymond Seed and Robert Bea of the University of California, Berkeley, released a draft of the group's findings, allowing engineers to improve plans for repairs. The levee study was one of more than 100 research projects NSF supported in response to the destruction caused by Hurricanes Katrina and Rita in 2005. The studies' results have provided emergency planners, responders and others with key findings ranging from how disasters inflict physical damage to the impact of social factors on evacuation and long-term emotional effects.

New Wi-Fi Network Brings Eye Care to Thousands in India
Researchers at the University of California, Berkeley, have developed a new technology for low-cost rural connectivity. As a result, thousands of residents from rural villages in India are receiving quality eye care for the first time. Based on "Wi-Fi" wireless networks, the new technology allows eye specialists to examine patients in five remote clinics via a high-quality videoconference using simple, inexpensive software and hardware. The system provides villages with a high-bandwidth connection to computer networks in cities as far as 50 miles away.

Formulating New Approaches for Studying Mind and Brain
Understanding how the brain generates meaningful behavior remains one of the great frontiers of science. Two NSF-organized workshops brought together researchers from across many disciplines to consider significant unexploited opportunities for mutual scientific benefit between brain science and the physical and mathematical sciences, computer science and engineering. Workshop participants focused both on scientific questions where a concerted effort could be expected to yield major advances in the next few years, and on the approaches and technical tools that need to be used in the investigation of these questions.

Astronomers Announce First Direct Observation of 'Dark Matter'
By observing a rare smash-up of galaxies traveling at 10 million miles per hour, astronomers have made the first direct detection of "dark matter"-- the mysterious, invisible stuff that comprises at least one-quarter of the universe. Because dark matter neither emits nor reflects light and only interacts with ordinary matter through gravity, its existence had been inferred but never observed directly before researchers studied a remarkable cosmic structure called the bullet cluster--actually two clusters of galaxies passing through one another. Discover magazine listed the discovery as the third most important science story of 2006.

Genetic Archaeology Finds Clues to Pregnancy in Male Pipefish, Seahorses
A gene discovered in the gulf pipefish, a member of the seahorse family, hints that a gene already busy with kidney and liver function may have learned new tricks in the male womb. Male pipefish accept eggs from the females, fertilize them and carry them in pouches. These brood pouches have evolved into complex organs able to nurture and protect the eggs. Researchers at Michigan State University determined that in its early days, possibly thousands of years ago, an atristacin gene--a type of protein gene--likely assisted in kidney and liver function. They think it is possible the gene was drafted into supporting the then-newfangled male brood pouch. Eventually, the gene became productive at its second job.

Volcanic Blast Likely Killed and Preserved Juvenile Fossil Plesiosaur Found in Antarctica
An American-Argentine research team has recovered the well-preserved fossil skeleton of a juvenile plesiosaur--a marine reptile that swam the waters of the Southern Ocean roughly 70 million years ago. The fossil remains represent one of the most complete plesiosaur skeletons ever found and is thought to be the best-articulated fossil skeleton ever recovered from Antarctica. Scientists found the skeleton while working at an elevation of 650 feet amid 70-mile-an-hour winds and freezing conditions on Vega Island. NSF and the Instituto Antártico Argentino funded the expedition.
