Universe's hidden supermassive black holes revealed

A Hubble Space Telescope color image of one of the nine galaxies targeted by NuSTAR. The high-energy X-rays detected by NuSTAR revealed the presence of an extremely active supermassive black hole at the galaxy center, deeply buried under a blanket of gas and dust.Astronomers have found evidence for a large population of hidden supermassive black holes in the Universe.

Dagger-like canines of saber-toothed cats took years to grow

This partial fossilized jaw is from a baby <i>Smilodon fatalis</i>. At the time of the cat's death, one of its adult canines (inside, left) was erupting alongside the baby canine. The adult carnassial/shearing tooth (inside, right) can also be seen alongside the milk tooth.New research shows that the fearsome teeth of the saber-toothed cat Smilodon fatalis fully emerged at a later age than those of modern big cats, but grew at a rate...

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...

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...

Old World monkey had tiny, complex brain

The brain hidden inside the oldest known Old World monkey skull has been visualized for the first time. The ancient monkey, known as <em>Victoriapithecus</em>, first made headlines in 1997 when its 15 million-year-old skull was discovered on an island in Kenya's Lake Victoria. Now, thanks to high-resolution X-ray imaging, researchers have peered inside its cranial cavity and created a three-dimensional computer model of what the animal's brain likely looked like. Its tiny but remarkably wrinkled brain supports the idea that brain complexity can evolve before brain size in the primate family tree. The creature's fossilized skull is now part of the permanent collection of the National Museums of Kenya in Nairobi.The brain hidden inside the oldest known Old World monkey skull has been visualized for the first time. The creature's tiny but remarkably wrinkled brain supports the idea that brain...
