Professor Reppert says scientists thought they understood the control system in the monarchs until they took a closer look at the insects’ antenna. He says the antenna can identify odors, as well movement, sounds and changes in barometric pressure. It can also sense light. The antenna sends information to the brain of the butterfly, controlling its behavior.

Climate Change E-Mails
BOB DOUGHTY: Earlier this year, we told about an incident that brought attention to disagreements about the cause of rising temperatures in Earth’s atmosphere. Private e-mails and documents were stolen from the Climatic Research Unit at the University of East Anglia in Britain. The information was placed on the Internet.
Recently, a British parliamentary committee finished its investigation of the incident. The committee released a mixed report about the leaked or hacked e-mails.
The investigators say they found no evidence that the university’s scientists cheated to prove the existence of human-caused climate change. The report said the director of the Climatic Research Unit did not attempt to hide evidence disputing the warming of Earth’s atmosphere. But it criticized the University of East Anglia for holding back information from other scientists. The investigators said the secrecy may have violated Britain’s public information laws.
STEVE EMBER: Parliament appointed a fourteen-member committee to investigate the case. The report said information requests by scientists not connected with the Climatic Research Unit, the C.R.U., were continually rejected. Those scientists included researchers who question the idea that human activity is causing temperatures in the atmosphere to rise.
