Dogs pant and rats chirp to express mirth/laughter.

| |

This MSNBC story says various groups' studies suggest monkeys, dogs and even rats love a good laugh. People, meanwhile, have been laughing since before they could talk. "Indeed, neural circuits for laughter exist in very ancient regions of the brain, and ancestral forms of play and laughter existed in other animals eons before we humans came along with our 'ha-ha-has' and verbal repartee," says Jaak Panksepp, a neuroscientist at Bowling Green State University.

Octopus species that can walk with two arms!

| | | |

Yahoo! News reports two little species of Indian Ocean octopus can tuck up six of their arms while running on the other two, U.S. researchers reported on Thursday. They can use their other six arms to disguise themselves from predators, either as rolling coconuts or clumps of floating algae, the team at the University of California Berkeley and Universitas Sam Ratulangi/Sam Ratulangi University in North Sulawesi, Indonesia found. The discovery, published in Friday's issue of the journal Science, discredits theories that walking requires hard bones and skeletal muscle, as octopuses have neither. The story has a streaming video clip as well.

Global warming could trigger ant invasions...

| |

New Scientist reports that global warming may lead to an unexpected threat from the insect world -- swarming invasions of tiny ants -- suggests new research. The study of 665 ant colonies in environments ranging from tropical rainforests to frozen tundra suggests that in warmer environments the ants' body size shrinks, on average, while the number of individuals in the colony booms.

Herrings/Fish That Fart.

| |

Blue's News posted a story about fish (herrings) that fart:

Dr. Batty, who works at the Dunstaffnage marine centre near Oban, and his colleagues were looking at whether herrings could detect sounds made by predators like whales and dolphins. Using infrared lighting with video cameras and underwater microphones, they monitored the herrings behaviour round the clock. "We heard these rasping noises, which sound like high pitched raspberries, only ever at night, whenever we saw tiny gas bubbles coming from the herrings' bottoms," said Dr Batty. "We also noticed that individual fish release more bubbles the more fish are in the tank with them. In other words, it seems that herring like to fart in company," commented Dr. Wilson.

How tunes get stuck in your head...

| | |

This BBC NEWS article says Scientists may have found what makes a tune catchy, after locating the brain area where a song's "hook" gets caught. A US team from Dartmouth College, reported in the journal Nature, played volunteers tunes with snippets cut out. They scanned for brain activity and found it centred in the auditory cortex -- which handles information from ears. When familiar tunes played, the cortex activity continued during the blanks - and the volunteers indeed said they still mentally "heard" the tunes.

A report says milk alone not best for children's bones.

| | |

CNN.com reports that children, who drink more milk, do not necessarily develop healthier bones, researchers said on Monday in a report that stresses exercise and modest consumption of calcium-rich foods such as tofu. The U.S. government has gradually increased recommendations for daily calcium intake, largely from dairy products, to between 800 and 1,300 milligrams to promote healthy bones and prevent osteoporosis. But the report, published in the journal Pediatrics, said said boosting consumption of milk or other dairy products was not necessarily the best way to provide the minimal calcium intake of at least 400 milligrams per day.

Urine Smell: A Magnet for Female Mice

| | |

FOXNews.com report that the distinctive "male" smell was discovered in urine from male mice. It's produced by a chemical called MTMT (methylio) methanethiol. Female mice don't make MTMT. Neither do castrated male mice, which lack sex hormones. The compound converts easily into an odoriferous gas. Many compounds in the urine are used to signal reproduction and territorial recognition, say the researchers.
