Sexual reproduction and evolution

The utility of sex, according to an intriguing new theory of evolutionary biology, may be its ability to promote genes that play well with many other partners rather than those that shine with just one specific set of genes.

Scientists discover an important new layer of regulation in the cell division cycle

A Florida State University College of Medicine research team led by Yanchang Wang has discovered an important new layer of regulation in the cell division cycle, which could lead to a greater understanding of the way cancer begins.

Doctors hesitant to discuss options to preserve fertility with cancer patients

Although some teenagers and young adults become infertile following cancer treatment, physicians are hesitant to discuss options to preserve fertility with patients, according to a new Florida study.

A virus-infecting virus

Using the Genome Sequencer System from 454 Life Sciences, a Roche company, French scientists have identified a small virus that can actually be parasitic to a larger one.

By imaging live cells, researchers show how hepatitis C replicates

The hepatitis C virus is a prolific replicator, able to produce up to a trillion particles per day in an infected person by hijacking liver cells in which to build up its viral replication machinery.

Discovery of new gene responsible for puberty disorders

A new gene responsible for some puberty disorders has been identified by Medical College of Georgia researchers.

Depressed pregnant women have twice the risk of preterm delivery

Depressed pregnant women have twice the risk of preterm delivery than pregnant women with no symptoms of depression, according to a new study by the Kaiser Permanente Division of Research. The study is published online in the Oxford University Press's journal Human Reproduction on behalf of the European Society of Human Reproduction and Embryology.

Sunshine could help fix male infertility

Australian fertility experts say a dose of daily sunshine could help men with fertility problems and they suggest couples struggling to conceive should consider getting out in the sunshine more often.

Why do women typically experience poorer dental health than men?

Reproduction pressures and rising fertility explain why women suffered a more rapid decline in dental health than did men as humans transitioned from hunter-and-gatherers to farmers and more sedentary pursuits, says a University of Oregon anthropologist.

New maturation inhibitor drugs may help solve HIV treatment conundrum

Since AIDS was first recognized in 1981, significant advances have been made in developing an effective arsenal of drugs to manage the disease and extend patients' lives.

Landmark study unlocks stem cell, DNA secrets to speed therapies

In a groundbreaking study led by an eminent molecular biologist at Florida State University, researchers have discovered that as embryonic stem cells turn into different cell types, there are dramatic corresponding changes to the order in which DNA is replicated and reorganized.

Squirrels may know a cure for cancer!

Scientists in the United States believe they have discovered a previously unknown anti-cancer mechanism in some rodents.

Herpes virus changes anti-herpes drug acyclovir to form that hinders AIDS virus

The drug acyclovir has long been used to suppress outbreaks of oral and genital herpes. Herpes viruses change acyclovir to a form that prevents them from reproducing.

National Toxicology Program finalizes report on Bisphenol A

Current human exposure to bisphenol A (BPA), a chemical used in many polycarbonate plastics and epoxy resins, is of "some concern" for effects on development of the prostate gland and brain and for behavioral effects in fetuses, infants and children, according to a final report released today by the National Toxicology Program (NTP).

Anti-itching drug clemizole shows promise against hepatitis C

The fight against the liver disease hepatitis C has been at something of an impasse for years, with more than 150 million people currently infected, and traditional antiviral treatments causing nasty side effects and often falling short of a cure. Using a novel technique, medical and engineering researchers at Stanford University have discovered a vulnerable step in the virus' reproduction process that in lab testing could be effectively targeted with an obsolete antihistamine.

Alcohol's effects on childbearing onset across reproductive development

Alcohol use during the teen years can not only lead to subsequent alcohol problems, it can also lead to risky sexual behavior and a greater risk of early childbearing. An examination of the relationship between a lifetime history of alcohol dependence (AD) and timing of first childbirth across reproductive development has found that AD in women is associated with delayed reproduction.

Sngle-walled carbon nanotubes used as cancer drug delivery vehicles

The problem with using a shotgun to kill a housefly is that even if you get the pest, you'll likely do a lot of damage to your home in the process. Hence the value of the more surgical flyswatter.
