Womb ops mean that men ‘could get pregnant tomorrow’ as surgeons develop new transplant techniques

Men could become pregnant ‘tomorrow’ thanks to advances in womb transplantation, according to a leading fertility expert.

The success of womb transplants into women has paved the way for a similar operation being carried out on people born male.

Dr Richard Paulson said that now wombs have been successfully transplanted into women born without them, ‘trans women’ – people born biologically male but who have had sex change surgery – will also want a womb transplant.

Prehistoric teeth fossils dating back 9.7 million yrs found in Germany ‘could rewrite human history’

Archaeologists in Germany have discovered a 9.7 million-year-old set of fossilised teeth they say could trigger the “rewriting” of human history.

The dental remains were found by scientists sifting through gravel and sand in a former bed of the Rhine river near the town of Eppelsheim.

They resemble those belonging to “Lucy”, a 3.2 million-year-old skeleton of a human ancestor found in Ethiopia.

Mars may be more inhospitable than previously thought, after Exomars rover confirms the presence of UV-activated chemicals that inhibit the development of living organisms


Terraforming Mars may have to wait yet a while longer.
The Martian surface is covered in UV-activated chemicals that inhibit the development of any lifeforms, as recent tests of the topsoil have shown.

ESA’s Exomars rover will now begin digging under Mars’ toxic surface, searching for any proof of current or past life on the planet.
Recent tests conducted on Martial soil have confirmed that oxidant compounds known as perchlorates permeate the the Red Planet’s surface.
Perchlorates are highly oxidized forms of chlorine, a chemical commonly used in household cleaning products and also as a disinfectant in swimming pools. The downside of it is that at high concentrations, chlorine is extremely toxic. It was weaponised and used as a chemical warfare agent during the First World War, for example.

Straight men’s physiological stress response to seeing two men kissing is the same as seeing maggots


In heterosexual men, pictures of rotting flesh, maggots and spoiled food induce the same physiological stress response as pictures of two men kissing each other. That is the surprising finding that was recently published in the peer-reviewed scientific journal Psychology & Sexuality.
“We originally were interested in understanding the health effects of same-sex vs. mixed-sex public displays of affection for the couples in the relationship,” explained the study’s corresponding author, Karen L. Blair of St. Francis Xavier University.
