The bizarre mating habits of flatworms

Microscopic image of <em>Macrostomum hystrix</em> shows the anterior eyes (1) in the head, followed by the paired testes (2), paired ovaries (3), developing eggs (4), the female genitalia containing three mature eggs (5), and the male genital region in the tail of the worm (6).Failing to find a mating partner is a dent to the reproductive prospects of any animal, but in the flatworm species Macrostomum hystrix it might involve a real headache. Zoologists...

Dagger-like saber-toothed cat canines took years to grow

<p>This partial fossilized jaw is from a baby <em>Smilodon fatalis</em>. At the time of the cat's death, one of its adult canines (inside, top) was erupting alongside the baby canine (bottom).The fearsome saber-toothed cat teeth may have fully emerged later in life than those of modern big cats, but they grew at a rate about double that of their living...

Rosetta spacecraft sees sinkholes on comet

This close-up image shows the most active pit, known as Seth_01, observed on the surface of comet 67P/Churyumov-Gerasimenko by the Rosetta spacecraft. A new study suggests that this pit and others like it could be sinkholes, formed by a surface collapse process similar to the way these features form on Earth.The European Space Agency's Rosetta spacecraft first began orbiting comet 67P/Churyumov-Gerasimenko in August 2014. Almost immediately, scientists began to wonder about several surprisingly deep, almost perfectly circular pits on the...
