Helium is drifting away.In America, helium is running out of gas. The element that lifts things like balloons, spirits and voice ranges is being depleted so rapidly in the world’s largest reserve, outside of Amarillo, Texas, that supplies are expected to be depleted there within the next eight years. This deflates more than the Goodyear blimp and party favors. Its larger impact is on science and technology, according to Lee Sobotka, Ph.D., professor of chemistry and physics in Arts & Sciences at Washington University in St. Louis.

NASA/JPLThick or thin ice shell on Jupiter’s moon Europa? Scientists are all but certain that Europa has an ocean underneath its surface ice, but do not know how thick this ice might be.Jupiter’s moon Europa is just as far away as ever, but new research is bringing scientists closer to being able to explore its tantalizing ice-covered ocean and determine its potential for harboring life. William B. McKinnon, professor of earth and planetary sciences at Washington University in St. Louis, is discussing some of these recent findings and new opportunities for exploring Europa in a news briefing on Thursday, Dec. 13, 2007, at the meeting of the American Geophysical Union in San Francisco.

More than 75 students in Washington University’s Mechanical and Aerospace Engineering Senior Capstone Design Course, a fast-paced studio experience in which student teams develop designs and construct working prototypes, will display their class projects, including a portable, collapsible disaster shelter and a high-capacity peanut-shelling system to speed the process of making peanut-butter medicine in Third World countries. The Mechanical and Aerospace Engineering Design Fair features 26 student projects on display from 10:30 a.m.-1 p.m. Tuesday, Dec. 11, in Lopata Hall’s atrium/gallery on Washington University’s Danforth Campus.

Instead, these are the components of a new high-school science curriculum being developed by researchers at Washington University and two St. Louis area high-school teachers.

Pratim Biswas has a method that controls the size of the nanoparticles he makes, opening up possibilities for new nanotechnology applications and different techniques.In a world that constantly strives for bigger and bigger things, WUSTL’s Pratim Biswas, Ph.D., the Stifel and Quinette Jens Professor and chair of the Department of Energy, Environmental and Chemical Engineering, is working to make things smaller and smaller. Biswas conducts research on nanoparticles, which are the building blocks for nanotechnology. For the first time, Biswas has shown that he can independently control the size of the nanoparticles that he makes, keeping their other properties the same. He’s also shown with his technique that the nanoparticles can be made in large quantities in scalable systems, opening up the possibility for more applications and different techniques.

Kranz, Ph.D., professor of biology in Arts & Sciences at Washington University in St. Louis, has been awarded two grants from the National Institutes of Health (NIH) to study pathways in bioenergy conversion. The first, for $1,203,250, is a long-term NIH R01 renewal that began Aug. 1 titled “Cytochrome c Biogenesis.” The renewal award means that NIH has funded Kranz continuously for 22 years.

David Kilper/WUSTL PhotoA math problem review session at the Kumon-Ladue math program on Clayton Road in Ladue.Parents of school-aged children might want to think of giving their children an enduring holiday gift this year: enrollment in a supplemental mathematics program. While it can cost anywhere from $80 to $110 a month, the results of practicing mathematics nearly daily is rewarding to both students and parents. In fact, parents might be even bigger recipients of this gift than their children. While their children gain self-esteem and confidence, the parents very likely will feel a sense of relief and pride in their children’s accomplishment.

Timothy Trinidad leads a discussion with classmates (from left) David Schainker, Helena Wotring and Mamta Datwani. The students are part of a computer science engineering course taught by Burchan Bayazit, Ph.D., assistant professor of computer science and engineering. The course stresses “active learning,” and features group work, presentation skill and critiques.Kenneth J. Goldman, Ph.D., associate professor of computer science and engineering, is the recipient of a $562,000 grant from the National Science Foundation that will enable his department to transform undergraduate teaching methodology. Goldman and his fellow principal investigators are working to cultivate “active learning” in the classroom, with a significant increase in studio courses that involve team projects and interdisciplinary collaboration. In a culture marked by frequent critique, students will refine their design skills, as well as improve their ability to present and justify their designs and work in groups. Passive learning, typified by the traditional lecture, will be put on the backburner, though the flame will still burn low.
