This insect's unique reproductive biology could lead to new ways to control the species in the environment – and prevent the deadly sleeping sickness it spreads to people.
Using new technology to answer questions about shark reproduction.
Researchers are using a newly developed satellite tag to study previously unknown aspects of tiger shark reproduction. This approach could be used on other difficult-to-study shark species.
The three-toed skink can give birth to live young and lay eggs in the same pregnancy. What can this little critter teach us about the evolution of live birth?
Although the United Nations has raised concerns about the rights of children, advocates say a baby hatch, like the one shown here in Karlsruhe, Germany, can save lives.
Since an infant was found in a recycling bin last fall in Saskatoon, advocates have renewed their campaign for baby hatches, places mothers can leave newborns safely and anonymously.
We found that women who had sex at least weekly or monthly were less likely to enter into early menopause compared to women who engaged in sexual activity less often.
The debate about why women have a clitoris has long been shaped by cultural, religious and moral influences.
New research suggests the clitoris is equally as important for reproduction as it is for sexual pleasure. But the evidence behind that claim is up for debate.
For millennia, theologians taught that the sole purpose of sex was reproductive. Now, almost everyone agrees that sex has many purposes – and benefits.
The purpose of sex may seem obvious, but it has perplexed and intrigued a variety of great minds for millennia.

How and why animals develop as male or female is far more complex than we ever imagined.
According to the United Nations, the world’s population could reach 10 billion by 2050.
The UN's new global population projections include some surprises – in particular, that the global population in 2100 will be 3% less than they projected in 2017.
When it comes to reproduction, couple have more choices than ever before.
A ban on clinical trials involving gene editing rules out the controversial procedure done in China. But it also prevents procedures that could offer couples a chance for healthy children without genetic disorders.

Approximately 25% of women – representing all races and backgrounds – will undergo an abortion before the age of 45.
New research shows dolphins have a large clitoris that is similar to the human organ.
It was not until the late 1990s that the anatomy of the human clitoris was accurately described by Australia’s first female urologist. And now research in animals is starting to catch up.
Welcome to the world, little lizard. A three-toed skink (
Saiphos equalis) hatching from an egg.
The evolution of live birth from egg-laying is no mean feat. Now new research reports on the first known example where both eggs and a live birth come from the same lizard pregnancy.
We’re having less sex than we used to.
Australians report having sex once or twice a week, on average, but there are many variables. And that's assuming people's estimates are accurate.
Birds and mammals use feathers and fur for staying warm and dry – but for other purposes too.
Finding a mate is of course essential to produce the next generation. And feathers and fur play key roles in making sure that happens.

Are pretty blue and gold stripes more important than being a bold little swimmer?
Acupuncture might alleviate stress for women undertaking IVF.
A new study has countered old reports acupuncture can improve your chances of having a baby when going through IVF.
The pain of infertility has not changed, even if modern technologies have.
It's 40 years since the birth of Louise Brown, the world's first test tube baby. But our long read explains how infertility has a much longer history.

About 20,000 Californians were once sterilized under state eugenics laws. New research shows Latinos were disproportionately targeted. Is there any opportunity today to address these wrongs?
