Histamine levels substantially higher in homes infested by bed bugs, study shows

New research findings could turn perceptions of the already despised bed bug from nuisance pest into medically important threat.

UIC scientists identify new chemical compound to stop bacteria from causing sickness

A study published in the Journal of Biological Chemistry is the first to describe a signaling pathway that affects communication -- a process called quorum sensing -- between Streptococcus bacteria cells.

Fruit flies' pheromones reveal sexual attractiveness of females

Life as a fruit fly seems pretty simple: Hatch, grow, eat some fruit, find a mate, produce hundreds of tiny offspring and die -- all in a month or so.

Duke researchers map evolution of sex chromosomes in fungus linked to human disease

Biologically speaking, nearly every species on Earth has two opposite sexes, male and female. But with some fungi and other microbes, sex can be a lot more complicated.

Japanese scientists show how male pheromone enhances female sexual behavior in mice

A study by a group of Japanese scientists showed how a male pheromone in mice enhances sexual behaviors in females--and how it may enhance a different behavior, aggression, in males -- by identifying distinct neural circuits and neurons that generate a particular behavioral response to specific chemical signals.

Males may play positive role in development of offspring's brains before pregnancy

A new study from Indiana University provides evidence in mice that males may play a positive role in the development of offspring's brains starting before pregnancy.

Hedione scent generates sex-specific activation patterns in brain

The question if humans can communicate via pheromones in the same way as animals is under debate. Cell physiologists at the Ruhr-Universität Bochum have demonstrated that the odorous substance Hedione activates the putative pheromone receptor VN1R1, which occurs in the human olfactory epithelium.

UC team to set off on research expedition funded by National Science Foundation

A University of Cincinnati team is about to set off on a National Science Foundation-funded research expedition in the Canadian Rocky Mountains.

Ant colonies can give evacuees better chance of reaching safe harbor after natural disaster

An escape route mapping system based on the behavior of ant colonies could give evacuees a better chance of reaching safe harbor after a natural disaster or terrorist attack by building a map of showing the shortest routes to shelters and providing regular updates of current situations such as fires, blocked roads or other damage via the smart phones of emergency workers and those caught up in the disaster.

CSP analogues may attenuate S. pneumoniae virulence, resistance

The spread of virulent, antibiotic-resistant strains of Streptococcus pneumoniae may be controllable through the use of competence-stimulating peptide analogues, US researchers believe.

Potential pathway for drug development using photoreactions

For chemists, natural substances are compounds formed by organisms to fulfill the myriad biological functions. This biological activity makes them very interesting for industrial applications, for example as active agents in medication or as plant protection agents.

Fruit fly study shows how sex may be one of the secrets to good health and longer life

Sex may in fact be one of the secrets to good health, youth and a longer life - at least for fruit flies - suggests a new University of Michigan study that appears in the journal Science.

Male roundworms shorten the lifespan of females, say Stanford researchers

Researchers at the Stanford University School of Medicine have discovered that males of the laboratory roundworm secrete signaling molecules that significantly shorten the lifespan of the opposite sex.

Wisconsin scientists synthesize potent compounds to curb bacteria that cause staph infections

In an age when microbial pathogens are growing increasingly resistant to the conventional antibiotics used to tamp down infection, a team of Wisconsin scientists has synthesized a potent new class of compounds capable of curbing the bacteria that cause staph infections.

Keystone molecules in chemical communication, defense have dominant consequences in nature

Naturally occurring "keystone" molecules that have powerful behavioral effects on diverse organisms often play large but unrecognized roles in structuring ecosystems, according to a theory proposed in the June issue of BioScience.

Study: Neural-crest stem cells also play a key role in building olfactory sensory neurons

When our noses pick up a scent, whether the aroma of a sweet rose or the sweat of a stranger at the gym, two types of sensory neurons are at work in sensing that odor or pheromone.

Iridoid synthase can make powerful chemicals from catnip to vinblastine

Scientists have discovered an enzyme used in nature to make powerful chemicals from catnip to a cancer drug, vinblastine. The discovery opens up the prospect of producing these chemicals cheaply and efficiently.

Biologists solve long-standing scientific mystery of how mice first know to nurse or suckle

A team led by biologists at The Scripps Research Institute has solved the long-standing scientific mystery of how mice first know to nurse or suckle.

Newborn mice use mum's unique odour to begin breastfeeding

Researchers show for the first time that a mammal begins to suckle its mother's milk through a learned response built on learning her unique combination of smells. When it is born, the newborn is exposed to the smell of its mother's amniotic fluid and the baby then responds to those smells to feed.
