Scientists at Washington University in St. Louis long suspected that dueling findings about the impact of invasive species on biodiversity reflect the different sizes of study sites. Now field work confims that the impact of invasive species is different at small scales than at large ones. The scientists hope an understanding of this “scale dependence” will help settle arguments that have broken out in the scientific community and discourage recent popular science articles downplaying the damage invasives cause.

Nominations are being accepted for Washington University’s annual Faculty Achievement Awards, known as the Arthur Holly Compton Faculty Achievement Award and the Carl and Gerty Cori Faculty Achievement Award. The Compton Award is given to a distinguished member of the faculty from one of the six Danforth Campus schools and the Cori Award to a faculty member from the School of Medicine.The deadline to submit nominations is Friday, Feb. 15.

In Blue Front (2006), poet Martha Collins draws on news accounts and historical documents to depict the brutal, 1909 lynching in Cairo, IL. On Thursday, Jan. 24, Collins, the Visiting Hurst Professor of Creative Writing in Arts & Sciences, she will present a free public lecture on the craft of poetry.

“The first thing we’re going to do is teach you how to throw a punch,” says senior Melissa Freilich. No, it’s not Boxing 101. Earlier this fall, the Edison Ovations Series welcomed approximately 500 eighth-graders from across St. Louis for a special matinee performance by nationally acclaimed Aquila Theatre.

We would all like to believe that there is a kind of karma in life that guarantees those who cheat eventually pay for their bad behavior, if not immediately, then somewhere down the line. But a study of a new gene in the amoeba Dictyostelium discoideum suggests that, at least for amoebae, it is possible to cheat and get away with it.

 Super-TIGER  the WUSTL-led cosmic ray experiment, has just been given the green light for  a third circuit around Antarctica. If the balloon stays up for a complete circuit it will probably break the heavy-lift scientific ballooning record of 42 days — and bring in a rich haul of data about cosmic rays, charged particles that continually bombard the Earth from space. The team has gone positively piratical over the prospect of more booty.

Invisible high-velocity particles rain down on Earth day in and day out, but  it has taken 100 years and clever deduction  for physicists to figure out what they’re made of and where they come from. Although some details are still unclear, physicists have built a case that the cosmic rays are born in volleys of supernova explosions in OB associations, loose associations of hot, massive stars sprinkled throughout our galaxy.

Ah, the Christmas season. It’s the most wonderful time of the year. A time to celebrate peace, love and the religious beliefs of America’s religious majority – whether you like it or not.

Tis the season for perennial battles between true believers and atheists, between mass marketers and the devout souls who worry about blatant commercialization of “the holiday season.”  While it may seem like it’s getting worse then ever, learning more about the facts behind these arguments might help all of us understand one another a bit better, suggest legal and religious history experts at Washington University in St. Louis.

The Super-TIGER comic-ray experiment had a perfect launch Sunday 9:45 am  New Zealand Daylight Time. The enormous balloon that will carry it to the limits of Earth’s atmosphere was stretched out on the ice and then partially filled.  As it came up off the ice, the balloon rose over the downstream instrument. When it was directly overhead the Boss released the  two-ton cosmic-ray instrument and it was lofted effortlessly into the skies over Antarctica.
