New smart anti-microbial approach to preventing tooth decay

Preventing cavities could one day involve the dental equivalent of a military surgical strike. A team of researchers supported by the National Institute of Dental and Craniofacial Research report they have created a new smart anti-microbial treatment that can be chemically programmed in the laboratory to seek out and kill a specific cavity-causing species of bacteria, leaving the good bacteria untouched.

Father's pheromonal cues may influence daughter's first occurrence of menstruation

Chemical cues from fathers may be delaying the onset of sexual maturity in daughters, as part of an evolutionary strategy to prevent inbreeding, according to researchers at Penn State.

Olfactory epithelium plays a critical role in pheromone detection

Howard Hughes Medical Institute researchers have discovered that pheromones essential for mating behavior in mice are recognized by the nose and not by the vomeronasal system, as researchers had long suspected.

First step in exploring the GnRH reproduction-related circuitry in the brain

Howard Hughes Medical Institute researchers have discovered a vast network of neurons in the brain of mice that governs reproduction and controls the effects of reproductive status on other brain functions.

Secrets of how the brain is wired for sex revealed

There are two brain structures that a mouse just can't do without when it comes to hooking up with the mate of its dreams--and trying to stay off the lunch menu of the neighborhood cat. These are the amygdala, which is involved in the initial response to cues that signal love or war, and the hypothalamus, which coordinates the innate reproductive or defensive behaviors triggered by these cues.

Swedish study suggests gay men's brains differ from heterosexual men's

Researchers in Sweden have found that a compound taken from male sweat stimulates the brains of gay men and straight women but not heterosexual men, which raises the possibility that homosexual brains are different.

Natural organohalogens have potent anticancer and antibacterial activity

Human made chemical compounds called organohalogens get loads of attention as they are best known for their often harmful effect on the environment - substances like the CFCs (the ozone-damaging chemicals), dioxin (found in the herbicide Agent Orange), PCBs (industrial fluids) and several pesticides.

Oxidants are responsible for sex in algae

Colonies of the multicellular green alga Volvox carteri exposed to temperatures of 111 degrees Fahrenheit (42.5 degrees Celsius) had twice the amount of free radicals, oxidants that can damage biological structures, as unheated colonies. High levels of oxidants within their cells activated the algae's sex-inducer gene, the researchers report.

How rat's genetic blueprint stacks up against those of mice and humans

An international research team, supported by the National Institutes of Health (NIH), today announced it has completed a high-quality, draft sequence of the genome of the laboratory rat, and has used that data to explore how the rat's genetic blueprint stacks up against those of mice and humans.
