g LIFE - A new study indicates that the oceans of Earth may be acidifying faster today than they did in the last 300 million years. If the trend continues, it may bring about dramatic changes for marine species on our planet. See article.
g MESSAGE - There are two interconnected, inverse and direct, problems in concept of extraterrestrial intelligence - Search for ETI by terrestrial intelligence and Messages to ETI from terrestrial intelligence. The key element of SETI is the Object of search, namely Universe, where we hope to detect the ETI and then to decode theirs Messages, and so the essence of SETI is Space Science. In turn, the key element of METI is the intellectual subject, who creates new messages for potential ETI and hope that They will detect and perceive these Messages, and so the essence of METI is Space Art. Of course, both SETI and METI have both scientific and art components, but it's important to underline that dominant of SETI is Science, and dominant of METI is Art. Also, the Messages for ETI might content both terrestrial knowledge and art, however scientific objective laws, known to terrestrials probably similar to ETI one, in turn the terrestrial subjective Art is unique and definitely unknown to ETI. See article.
g LEARNING - Scientists have revealed new information about the "man in the Moon" many people see when gazing at our familiar celestial neighbor. See article.
