The battle of the sexes is a never-ending war waged within ourselves as male and female elements of our own bodies continually fight each other for supremacy. This is the astonishing implication of a pioneering study showing that it is possible to flick a genetic switch that turns female ovary cells into male testicular tissue.

For decades, the battle of the sexes has been accepted by biologists as a real phenomenon with males and females competing against each other — when their interests do not coincide — for the continued survival of their genes in the next generation. Now scientists have been able to show that a gender war is constantly raging between the genes and cells of one individual.

One of the great dogmas of biology is that gender is fixed from birth, determined by the inheritance of certain genes on the X and Y sex chromosomes. But this simplistic idea has been exploded by the latest study, which demonstrated that fully-developed adult females can undergo a partial sex change following a genetic modification to a single gene.

In a study published on May 7, 2020, in Current Biology, researchers from University of Sydney have identified the single gene that determines how Cape honey bees reproduce without ever having sex. One gene, GB45239 on chromosome 11, is responsible for virgin births.

“It is extremely exciting,” said Professor Benjamin Oldroyd in the School of Life and Environmental Sciences. “Scientists have been looking for this gene for the last 30 years. Now that we know it’s on chromosome 11, we have solved a mystery.”

Behavioral geneticist Professor Oldroyd said: “Sex is a weird way to reproduce and yet it is the most common form of reproduction for animals and plants on the planet. It’s a major biological mystery why there is so much sex going on and it doesn’t make evolutionary sense. Asexuality is a much more efficient way to reproduce, and every now and then we see a species revert to it.”

In the future, people getting ready for a flight — and fearing impending jet lag — might fit an assortment of additions into their carry on: masks, gloves, and maybe a medicinal mushroom hailed for delivering animalistic sex drive.

That’s because a new study suggests that a synthetic form of cordycepin, a compound found in a medicinal fungus with a reputation for keeping bedroom doors closed, may help ease the pain of jet lag.

As the novel coronavirus swept through communities around the world, preying disproportionately on the poor and the vulnerable, one disadvantaged group has demonstrated a remarkable resistance. Women, whether from China, Italy or the U.S., have been less likely to become acutely ill — and far more likely to survive.

Which has made doctors wonder: Could hormones produced in greater quantities by women be at work?

Now scientists on two coasts, acting quickly on their hunches in an effort to save men’s lives, are testing the hypothesis. The two clinical trials will each dose men with the sex hormones for limited durations.

The first study on vitamin D and COVID-19 was released as a preprint on April 23, and a second study was released as a preprint on April 26. Here’s what we can learn from the second study. The first study, which I reported on a few days ago, focused on disease severity, while the second one, which I’m reporting on here, focused on mortality.

The Results

The electronic health records of 780 laboratory-confirmed COVID-19 cases from the government hospitals of Indonesia between March 2 and April 24 was searched for data on vitamin D status prior to admission, age, sex, preexisting conditions, and mortality. Vitamin D status was classified as normal (≥30 ng/mL), insufficient (21−29 ng/mL), or deficient (≤20 ng/mL).

“It’s really hard to define a committed relationship and it’s really hard to define anything related to that,” Biggs said on Monday.

Proponents of the technology claim it can get people off of opioids, improve their sex lives, and make them smarter. Critics say it’s bunk.

As the coming genetic revolution plays out, we’ll still have sex for most of the same reasons we do today. But we’ll increasingly not do it to procreate.

Another rocket booster will be the application of gene editing technologies like CRISPR to edit the genomes of pre-implanted embryos or of the sperm and eggs used to create them. Just this week, Chinese researchers announced they had used CRISPR to edit the CCR5 gene in the pre-implanted embryos of a pair of Chinese twins to make them immune to HIV, the first ever case of gene editing humans and a harbinger of our genetically engineered future. The astounding complexity of the human genome will put limits on our ability to safely make too many simultaneous genetic changes to human embryos, but our ability and willingness to make these types of alterations to our future children will grow over time along with our knowledge and technological ability.
