- Cane toads, reptiles imported into Australia in the erroneous belief that they would eliminate pests from sugar-cane fields, are attracted by disco-style flashing lights, said researchers in the Northern Territory who are desperate to find a way of eliminating the fast-spreading creatures. "The old toads are definitely a disco animal," said a member of a group called Frogwatch.
- A Swiss woman sees colors and experiences tastes when she hears music, scientists at the University of Zurich in Switzerland reported. The rare phenomenon, known as synaesthesia, was confirmed in a 27-year-old professional musician, who saw violet on hearing an F sharp and red on a middle C.
- Researchers at National University in La Jolla, California, threw a dinner party and then analysed the leftovers to see if their guests left significant DNA samples on them. Complete profiles were recovered from 43 percent of the sample, and partial ones from 33 percent. Such work could be useful in catching burglars, who often like tucking into the food found in their victims' kitchens.
- African elephants have at least one thing in common with parrots: they imitate sounds they hear around them, said scientists in the United States and Norway. A captive female jumbo in Kenya was found to imitate the noise of trucks on a nearby road, while a male kept with Asian elephants at a zoo in Switzerland mimicked their chirping noises.
- Enterprising students at Brown University in the United States invented an alarm clock that monitors its user's brainwaves and works out the best time to wake him or her up. The only drawback: the sleeper must wear a headband equipped with electrodes.
- Alexis Lemaire, a 24-year-old student in Reims, France, claimed a world record for working out the 13th root of a 200-digit number by mental arithmetic. The feat, checked by a notary, took him 48 minutes and 51 seconds.
- Also in the math department, Akira Haraguchi, a 59-year-old psychiatric counselor in Japan, recited from memory the value of "pi", a constant which consists of an infinite string of digits, to 83,431 decimal places. It took him 13 hours to beat the previous record, also set by a Japanese, of a mere 54,000 digits.
- An odd-looking rodent spotted on sale for meat in a Laotian food market turned out to be not only a new species but also the first member of a new family of mammals to be identified in more than three decades. An alert member of the New York-based Wildlife Conservation Society noticed the creature, which was baptised a stone-dwelling puzzle-mouse - or, more simply, "rock rat".
- The fashion for television detective series which focus on forensic science may be unwittingly providing tips to real-world criminals, a study by British researchers said. Some forensic scientists were even becoming unwilling to cooperate with the media for precisely that reason.
- Proof that scientists have a sense of humor: the annual Ig Nobel awards, which give spoof prizes to the most offbeat research. This year's crop went to the inventor of an alarm that rings then runs away and hides, thus ensuring that the sleeper has to get up to turn it off... to scientists who researched whether humans swim faster in syrup rather than in water... to British boffins who analysed the electrical activity of a locust's brain cell while the insect watched a "Star Wars" movie... and to a German team that calculated the pressure produced in penguins' anuses when the birds expel their faeces.
- The guardians of animal nomenclature had mixed feelings over a proposal to name three newly-discovered species of slime-mould beetle after US President George W. Bush, Vice President Dick Cheney and Defense Secretary Donald Rumsfeld. A pair of insect experts reserved the names Agathidium bushi, Agathidium cheneyi and Agathidium rumsfeldi for their latest creepy-crawlies.
