Butterflies released into Fermilab’s natural areas

Fermilab is the new home to Baltimore checkerspot butterflies, released by scientists from Chicago’s Peggy Notebaert Nature Museum late last month.

Native to North America, Baltimore checkerspot butterflies once thrived in wetlands in the northeastern and Midwestern regions of the United States. A steady decline in natural habitats has made them an imperiled species, at risk of becoming endangered.

In 2009, the nature museum made its first attempt to introduce the butterflies to Fermilab’s wetlands. Museum staff placed Baltimore checkerspot caterpillars onto their host plant, white turtlehead, which Fermilab volunteers had grown on site as part of the ecological land management program to enhance Fermilab's wetlands with native plants.

But the larvae didn’t survive the winter. The caterpillars that hatch from one egg mass typically spin a hibernation web and spend the winter together. Perhaps releasing them individually kept them from properly building their winter shelter, said Doug Taron, curator of biology at the nature museum.

This year the museum staff took a new approach: instead of caterpillars, they brought adult butterflies. In addition to releasing most of them into the open prairie, they placed a few butterflies in screened cages together with the turtlehead plants to increase the chances they would lay eggs on the plants. The cages were built a few years ago by Matthew Wischoeffer as part of an Eagle Scout project with Fermilab.

On Thursday, June 23, a windy and rainy day, Taron, along with the nature museum’s director of arthropod conservation, Vincent Olivares, and a group of conservation workshop attendees, came to Fermilab to release the butterflies.

Taron and Olivares placed two females and one male in each of three large cages. When the remaining butterflies didn’t emerge from their transport container, Taron explained to onlookers that it was too cold. They decided to take the rest of the butterflies back to the museum and wait for a warmer day.

They succeeded in releasing the butterflies on Saturday, June 25. About 70 butterflies fluttered out into the prairie between inbound and outbound Pine Street.

Antimatter Tevatron mystery gains ground

From BBC News, July 1, 2011

US particle physicists are inching closer to determining why the Universe exists in its current form, made overwhelmingly of matter.

Physics suggests equal amounts of matter and antimatter should have been made in the Big Bang.

In 2010, researchers at the Tevatron accelerator claimed preliminary results showing a small excess of matter over antimatter as particles decayed.

The team has submitted a paper showing those results are on a firmer footing.

Each of the fundamental particles known has an antimatter cousin, with identical properties but opposite electric charge.

When a particle encounters its antiparticle, they "annihilate" each other, disappearing in a high-energy flash of light.

The question remains: why did this not occur in the early Universe with the equal amounts of matter and antimatter, resulting in a Universe devoid of both?

Director's Corner on holiday

Due to the July 4 holiday, the regularly scheduled Director's Corner will not appear in today's issue.

"Don't step on the fuzzy caterpillars because one day they will become a beautiful butterfly," said PPD's Leticia Shaddix, who captured this photo of a caterpillar crawling up the side of a building on June 8.

Response to the Marx Report

From Homestake DUSEL and Sanford Laboratory Newsletter, June 2011

Editor's note: This article was written by Kevin Lesko, DUSEL principal investigator.

I am very pleased with the Report of the Committee Assessing Options for Underground Science, which was first revealed at the HEPAP meeting on June 23. The assessment team, which was expertly led by Jay Marx and Mark Reichanadter, was first rate, and they worked diligently and under extreme time pressure to answer the questions posed by the Office of Science.

I am gratified to see that the Committee was able to receive, readily understand, and make use of our advanced estimates and designs for the Homestake site. It is a testament to the DUSEL/SDSTA team’s hard work and attention to detail that we could effectively communicate our detailed Plans B and C in essentially a morning session in mid-April. In the assessment process, the Committee repeatedly recognized the quality of the DUSEL/SDSTA team and our work.

Essentially all of our major points are wellrepresented in the report including the benefits of a single facility to integrate and share the design, construction, and operations functions, the value to the US physics programs to have, using Jay's words, "the home field advantage" for these critical experiments, the importance of having a deep facility to host these experiments, and our ability to phase facility improvements and stage infrastructure additions as the experiments require them, rather than having to create them all at once.
