July 20 (Reuters) — The World Health Organization (WHO) has confirmed 14,000 cases of monkeypox worldwide, with five deaths reported in Africa, Director General Tedros Adhanom Ghebreyesus said on Wednesday.

Most of the cases reported thus far have been found in Europe, particularly among men who have sex with men, the WHO said, although all the deaths have occurred in Africa, the region where monkeypox outbreaks have historically been found.

On Thursday, the WHO will convene the second meeting of a committee that will decide whether the outbreak is a public health emergency of international concern (PHEIC), its highest level of alert.

The Y chromosome, involved in sex determination, mysteriously disappears from some men’s immune cells as they get older – and that could be fatal.

Despite the fact that sex is a basic instinct and a near-universal experience, we know remarkably little about it. And so, this week, we’re teaming up with our friends at Futurism, oracles of all things science, technology and medicine, to look at the past, present and future of pleasure from a completely scientific perspective.

For a while now, the neurotransmitter dopamine has been seen as the conductor of good feelings. It’s the subject of love songs, the seductress of biohackers and the ostensible “pleasure chemical.” But as research continues to uncover more about our brain’s reward system, dopamine is beginning to look less like the maestro and more like a member of the band.

Buoyed by research that says inhabiting someone else’s body can change how you perceive your own, researchers have started to investigate the vast, erotic potential of virtual sex.

It’s not easy being green.

Prostate cancer growth is driven by male sex hormones called androgens. And so, lowering levels of these hormones can help slow the growth of cancer.

Hormone therapy has been successful in keeping metastatic, or advanced prostate cancer, under control. Patients with metastatic prostate cancer often receive treatment with anti-hormonal therapy, which inhibits the signal sent out by testosterone that stimulates tumor growth.

But eventually, the tumor cells could become resistant to it. An international team of researchers led by the Netherlands Cancer Institute has now unveiled an “unexpected potential” solution, not designed to fight cancer but to target proteins that regulate a cell’s circadian rhythm.

From the engine in your car to the components in your laptop, mechanical systems tend to heat up when they’re working harder. Now new research has revealed that the same can be said of the brain – and it runs hotter than was previously thought.

Some parts of the deep brain can get up to 40 °C (104 °F), a new study shows, though this varies by sex, time of day, and various other factors. Compare that with the average oral temperature in human bodies, which is typically under 37 °C (98.6 °F).

This isn’t a sign of malfunctioning though, researchers think, and may actually be evidence that the brain is operating healthily. Unusual heat signatures could potentially be used in the future to look for signs of brain damage or disorder.
