Can you believe it, another 12 months over already? It seems they go by faster every year, and before we know it, it’ll be 2050 and we’re living on Mars.

Well, that’s the hope, but there’s quite a lot of scientific discovery to be done before then.

Luckily that’s happening at light speed too, and 2023 was no different, with major breakthroughs in astronomy, space travel, health and medicine.

All very noble pursuits, but let’s not forget about some of the more weird and wonderful discoveries and happenings. You know, the ones that make you think ‘why was anyone even looking into that?’, or just ‘huh?’.

There was no shortage of those either – like the horrifying of the sex life of the Pacific football fish, or what happens when you get worms stoned.

Answers

1. b – a bear. The strange image was taken by the Mars Reconnaissance Orbiter from 150 miles above the surface.

2. c – a woolly mammoth. The prehistoric snack was created by Australian company Vow, which aims to use cells from unconventional species to create new kinds of meat.

3. b – parents deformed their babies’ heads. Until this year it wasn’t known if the deformities were natural or deliberate. 

4. a – a frog. Paleontologists at University College Cork found the earliest evidence of pheomelanin, the pigment that produces ginger colouration, in the ancient specimens.

An ancient collision between Earth and another planet is believed to have formed the Moon (Picture: Deng Hongping and Hangzhou Spher)

5. d – The remains of another planet. Scientists think it belongs to a planet called Theia, which many believe crashed into Earth and formed the Moon.

6. b – and possibly d. Researchers found leather equipment made from human skin at a burial mound, something recorded by ancient Greek historian Herodotus – who also alleged they drank the blood of their enemies.

7. a – kill liver cancer cells. While the animal may look a bit like human faeces, scientists at the University of Philadelphia, USA, have discovered that it might also be able to save lives.

The serotine bat has some frankly astounding sexual behaviour (Picture: PA)

8. d – yes, they use their penis for grip. The bat appears to mate without penetration because its penis is around seven times longer and wider than the females’ vagina, making ‘traditional’ methods of reproduction physically impossible.
