Sometimes it’s hard to see what’s going on when you look at an ultrasound image of a baby in utero, but in this case the truth is plain to see-this woman’s baby is clearly the supervillain Venom, and he’s coming back for vengeance against Spider Man!
Giving birth to a supervillain might seem like a scary scenario, but really there are a lot of perks-your kid won’t get picked on at school, they will generally be able to take care of themselves, and every time they knock over a bank you’re in the money.
And at least her baby doesn’t look like Green Goblin, now that would have been terrifying!
On the left is a normal testicle. On the right is one that has been blasted with ultrasound. The latter has a reduced sperm count, which is why researchers at the University of North Carolina think that they may have discovered an effective male contraceptive:
They found that two, 15-minute doses “significantly reduced” the number of sperm-producing cells and sperm levels. [...]
Lead researcher Dr James Tsuruta said: “Further studies are required to determine how long the contraceptive effect lasts and if it is safe to use multiple times.”
The team needs to ensure that the ultrasound produces a reversible effect, contraception not sterilisation, as well as investigate whether there would be cumulative damage from repeated doses.

A biotech company named InSightec is developing a surgical technique that uses focused ultrasound waves instead of scalpels to destroy tumors:
Machinery like this had previously been used to treat some cancers, for example in the uterus and breast. But until now, the distorting effects brought about by the skull’s thickness has made it impossibly tricky to focus the beams onto the brain while also maintaining the required accuracy.
InSightec’s technology solves that by using over a thousand individually focused transducers, which broadcast the ultrasonic beams. But it’s not like shooting a laser into a person’s head–rather, the beams raise the temperature of the location being treated by about forty degrees, or just enough to kill the diseased cells. A built-in cooling system keeps the brain from
cooking like an eggoverheating.
Caterpillars of the Great Peacock Moth (Saturnia pyri) are making quite a buzz. A recent study has shown that these giant silkmoth caterpillars are advertising acoustically that they are unpallatable and warn of an upcoming defense strategy.
When disturbed by a would be attacker the caterpillars stridulate by rubbing their mouth parts together, creating broadband chirps spanning from 3.7-55.1 kHz. While it is still unclear who exactly they are advertising to, a predator would be well advised to stay away from their sharp, chemical exuding bristles.

Saturnia pyri chirp before or while they ooze foul-smelling droplets from their bristles. So the chirps might be a warning to attackers that there’s some serious resistance on the way, Yack and her colleagues propose online and in an upcoming Naturwissenschaften.
