Why recognizing sex pheromone components of the silkworm moth at the scale of atoms and molecules impacts on eco-friendly agriculture New research announced today, Wednesday 30th September, by a team of leading scientists working with the UK's national Synchrotron, Diamond Light Source, could have a significant impact on the development and refinement of new eco-friendly pest control methods for worldwide agriculture. Published in the Journal of Molecular Biology, the study was carried out by...

Biotechnology and Biological Sciences Research Council (BBSRC)-funded research, published this week in Chemical Communication, describes how scientists have discovered molecules that could confuse insects' ability to detect plants by interfering with their sense of smell. This could reduce damage to crops by insect pests and contribute to food security. Lead researcher Dr Antony Hooper of Rothamsted Research, an institute of BBSRC said: "One way in which insects find each other and their...

U.S. and Mexican scientists have linked gene expression in honeybees' brains in the response to threats with long-term and evolutionary aggression differences. The study involved scientists from the University of Illinois, the U.S. Department of Agriculture, the Fyssen Foundation, the National Institutes of Health, the Illinois Sociogenomics Initiative, Purdue University, the University of Guelph and the National Program of Epidemiology in Mexico. It utilized microarray analysis to measure...

U.S. scientists using a new form of high-resolution laser mass spectrometry say they have discovered a new fruit fly pheromone. Scientists led by Professor Edward Kravitz at the Harvard Medical School said they were scanning the surface of fruit flies when they discovered the previously unidentified pheromone -- CH503 -- that contributes to the anti-aphrodisiac effects observed in female fruit flies after copulation. The researchers said the anti-aphrodisiac effect of copulation had been...

Japanese scientists are involved in groundbreaking research to understand and then rebuild the brains of insects and program them for specific tasks, AFP reported. After studying insect brains for three decades, Ryohei Kanzaki, a professor at Tokyo University's Research Center for Advanced Science and Technology, has become a pioneer in the field of insect-machine hybrids. Kanzaki has been studying insects' "micro-brains" in order to move closer to his original and ultimate goal of...

Ohio State University scientists combined bed bugs' own chemical signals with a common insect control agent to create a more effective extermination method. The researchers said they discovered stimulating the bed bugs by spraying their environment with synthetic versions of their alarm pheromones makes them more likely to walk through agents called desiccant dusts, which kill the bugs by making them highly susceptible to dehydration. Doctoral candidate Joshua Benoit, the study's lead author,...

Researchers say they have begun placing a pheromone in Michigan streams in an attempt to lure female sea lampreys into traps. Researcher Nick Johnson of the Hammond Bay Biological Station said the pheromone was designed by scientists at Michigan State University to mimic a spawning scent emitted by male sea lampreys, the Detroit Free Press reported Sunday. Once they smell it, they follow it, Johnson said of the female of the prehistoric species. Since arriving in the Great Lakes eight decades...

Germany scientists have used gas chromatography to determine desert ants use their olfactory sense to find their way without landmarks for guidance. Researchers from the Max Planck Institute for Chemical Ecology discovered desert microhabitats have unique odor signatures that can be used to guide the ants back to their nest. Until now scientists thought the desert ant Cataglyphis fortis, which makes its home in the Tunisian desert, was a vision-guided insect. But the researchers -- Kathrin...

Scientists say a synthetic chemical sex smell could help rid North America's Great Lakes of a devastating pest known as the "vampire fish." A laboratory version of a male sea lamprey pheromone was deployed to trick ovulating females into swimming upstream into traps, US researchers said. The vampire fish, known formally as the sea lamprey, has become a harmful parasite to native species of the Great Lakes since its accidental introduction in the 1800s. Recreational fishing of the Great Lakes...

Women's brains recognize and encode the smell of male sexual sweat, U.S. psychologists said. Denise Chen of Rice University looked at how the brains of female volunteers processed and encoded the smell of sexual sweat from men. Scientists have long known that animals use scent to communicate, but Chen's findings represent an effort to expand knowledge of how humans' sense of smell complement their more powerful senses of sight and hearing. The researchers studied natural human sexual sweat...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
