Sexual cooperation: Mating increases longevity in ant queens

The phenomenon of sexual conflict is a powerful driving force in the evolution of reproductive biology for many animal species. Males often try to manipulate their female mates during copulation--for example, by traumatic inseminations (as in the case of bed bugs) or by the transfer of toxic seminal fluids (as in the case of the fruitfly Drosophila). These manipulations are beneficial to males be...

Cricket's finicky mating behavior boosts biodiversity

Biologists at Lehigh University and the University of Maryland have identified a cricket living in Hawaii's forests as the world's fastest-evolving invertebrate. Females in the Laupala genus detect tiny differenc...

Same-Sex Mating Discovered in a Toxic Fungus

An infectious fungus has been found to defy the most basic tenet of sexual reproduction ?that successful mating requires individuals of the opposite sex, according to Howard Hughes Medical Institute researchers at Duke University Medical Center. In the April 21, 2005, issue of Nature, the researchers reported that, in the infectious fungus Cryptococcus neoformans, members of the same "sex"...

PHACCS, an online tool for estimating the structure and diversity of uncultured viral communities using metagenomic information

In the March 3 issue of Nature, Johns Hopkins researchers report that two proteins best known for very different activities actually come together to turn the liver into a sugar-producing factory when food is scarce. Because the liver's production of sugar is a damaging problem in people with diabetes, the proteins' interaction might be a target for future drugs to fight the disease, the research...

Certain fish have a special mating preference

A biologist at Washington University in St. Louis has shown that for some fish species, females prefer males with larger sexual organs, and actually choose them for mating. That does not exclude males with an average-sized sex organ, called a gonopodium. These fish out-compete the larger-endowed males in a predator-laden environment because they have a faster burst speed than the males with large...

Strong Evidence Suggests Incidence Of Mating Of Ancestors With Neanderthals

A recent scientific study conducted at the Howard Hughes Medical Institute and the University of Chicago led by Bruce T. //Lahn suggests that human evolution may not be all about unprompted mutations that occurred on the spur of a moment but because of interbreeding with related species on the verge of extinction that resulted in the introduction of variant genes called alleles which has remarkab...

Biochemical Chip Solves Cell-mating Puzzle

Scientists have used a biochemical chip to explain the important role a certain protein plays in the mating habits of yeast cells. The finding could lead to new cancer drugs with fewer side effects. // A research team at The John Hopkins University, led by Andre Levchenko, have revealed in the journal Nature how they used their patented microfluidic chip to study yeast cells merging to...

Fruit Crop Fungicide Induces Permanent Changes in Mating Behavior

Austin— Researchers from The University of Texas have discovered the intuitive ability of female rats, who simply give a cold shoulder to male rats// whose descent is contaminated by a common fruit crop fungicide; instead they showed a preference to male rats whose ancestors were untainted. Their research shows that environmental contamination could affect the evolution of wildlife t...

Fishes Use Threat of Punishment in Mating Process

Australian marine scientists has found that fishes use the threat of punishment to keep would-be jumpers in the mating queue firmly in line and the social order stable. Their discovery, which has implications for the whole animal kingdom including humans, has been hailed by some of the worlds leading biologists as a must read scientific paper and published in the Proceedings of the R...

Amorous African Fish Exchange Electric Pulses While Mating

Some African fish signal their amorous intentions by exchanging bursts of electrical impulses, a new study has found . Scientists describe this behavior as being somewhat similar to the courtship duets of songbirds. According to the study, which has been reported by National Geographic, these fish produce weak electrical fields using specialized organs in their tails....
