To deter a predator, kill its young!

Prey have evolved a suite of tricks to avoid falling victim to a predator. They may escape, hide, protect, become toxic/inedible or defend themselves. In principle, they could also scare the predator away, but this is risky when predators are big. Recent work led by a Dutch research team and published in the July issue of Ecology Letters revealed that a plant-feeding thrips insect overcomes this differential size problem by killing the eggs of its enemy, a plant-inhabiting predatory mite. Th

Blue tits love the smell of perfumed nests!

French birds love the smell of perfumed nests. In an article published this month in Ecology Letters, scientists from the Centre National de Recherche Scientifique report that a small cavity-nesting bird on the island of Corsica, the blue tit, adorns its nests with fragments of strongly perfumed plants, including lavender and mint. The chemical compounds of these plants are economically important as they are used for aromatic house cleaners and herbal medicines. The researchers also discovered that t

Ecological communities suffer dramatic changes when non-native species are introduced by humans!

Ecological communities suffer dramatic changes when non-native species are introduced by humans. Such introductions have been documented in hundreds of locations and appear to be common in marine and island habitats. One of the best-studied cases of a species that suddenly appeared in the New England intertidal, and subsequently spread rapidly southward accompanied by significant changes in the intertidal community, is the “European periwinkle” Littorina littorea. In the July issue of Ecolog

Infant mortality rate drops, children more likely to have working parent, be read to

Children in America are less likely to die during infancy than they were in previous years, less likely to smoke in 8th or 10th grade, and less likely to give birth during adolescence, according to the 6th annual report, America’s Children: Key National Indicators of Well-Being, 2002. The report also noted improvements in some of the economic security indicators: children are more likely to have at least one working parent and to have health insurance. Moreover, children from ages 3 to 5 are mor

Astrophysicists discover possible nanodiamond formation in the early solar system

An astrophysicist from Lawrence Livermore National Laboratory’s Institute for Geophysics and Planetary Physics has found that some nanodiamonds, the most famous and exotic form of stardust, may instead have formed within the inner solar system. The findings argue with the wide held belief that nanodiamonds recovered from meteorites from the asteroid belt have been the most abundant type of presolar stardust grain. IGPP Director John Bradley, in conjunction with scientists from the Georg

Let’s talk about sex — And pain

Dr. Irv Binik investigates pain during intercourse For some women sex can be uncomfortable. For others it can be downright painful. Dr. Irv Binik, a Psychology professor at McGill and director of the Royal Victoria Sex and Couples Therapy Service is trying to ease the pain. He has been studying the problem of sex-associated pain in women, paying particular attention to two recurrent acute conditions, pain during or after intercourse (dyspareunia) and involuntary spasms of the vagina (v
