Space-time distortions around neutron stars, pulse-detection system and Communication with Extraterrestrial Intelligence

Welcome! “Alien Life” tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here’s today’s news:
g Stars - Using European and Japanese/NASA X-ray satellites, astronomers have seen Einstein's predicted distortion of space-time around three neutron stars, and in doing so they have pioneered a groundbreaking technique for determining the properties of these ultradense objects. See article.
g Life - Plant geneticists and animal breeders alike know the problem: single individuals or entire broods will not thrive, some die early, or remain, even if they survive, the runts of the litter and thus not useful for continued breeding programs. What is annoying for the breeder, fascinates geneticists and molecular biologists. The unfit offspring are an example that genetic material cannot always be combined at will. See article.
g Intelligence - Apes bite and try to break a tube to retrieve the food inside while children follow the experimenter's example to get inside the tube to retrieve the prize, showing that even before preschool, toddlers are more sophisticated in their social learning skills than their closest primate relatives, according to a report published in the 7 September issue of the journal Science. See article.
g Message - In 2001, California astronomers broadened the search for extraterrestrial intelligence with a new experiment to look for powerful light pulses beamed our way from other star systems. Scientists from the University of California's Lick Observatory, the SETI Institute, UC-Santa Cruz, and UC-Berkeley used the Lick Observatory's 40-inch Nickel Telescope with a new pulse-detection system capable of finding laser beacons from civilizations many light-years distant. Unlike other optical SETI searches, this new experiment is largely immune to false alarms that slow the reconnaissance of target stars. See article.
g Cosmicus - As the 21st century gets underway, the impact of space activities upon the welfare of humanity only will increase. See article.
g Learning - Here’s a neat set of lessons, designed for at-risk students: “The Plausibility of Interstellar Communication and Related Phenomena Depicted in Science Fiction Literature and the Movies.” The curriculum has four major objectives: first, to educate students to develop concepts about the proximity of our solar system in relation to other probable solar systems in the Milky Way Galaxy; second, to give students the opportunity to use these concepts to evaluate the plausibility of interstellar communication depicted in science fiction literature and movies; third, to create an opportunity for students not only to look out on the universe but to turn it inward to look at the world, their own society, and themselves as individuals; and fourth, an objective that will be integrated with all of the others is to give students to opportunity to learn and/or sharpen skills in: using the scientific method, research, reading, writing, collaboration, discussion and in critical thinking. See article.
g Imagining - Scientifically speaking, are UFOs worth keeping an eye on? Not exactly. See article.
g Aftermath - In the last quarter of the 20th century, an international social movement — Communication with Extraterrestrial Intelligence — has emerged which advocates an attempt to achieve communication with extraterrestrial intelligence, and many of its most active members have been leading scientists. Modest efforts to detect radio signals from intelligent extraterrestrials already have been made, both under government aegis and privately funded, and the technical means for a more vigorous search have been developed. If a CETI project were successful, linguists would suddenly have one or more utterly alien languages to study, and some consideration of linguistic issues is a necessary preparation for it.
