Scientists find 'oldest human ancestor'

Researchers have discovered the earliest known ancestor of humans - along with a vast range of other species according to BBC.

They say that fossilised traces of the 540-million-year-old creature are "exquisitely well preserved".

The microscopic sea animal is the earliest known step on the evolutionary path that led to fish and - eventually - to humans.

Researchers reveal ancient flying reptile with a mouth so big it could swallow a human whole

Researchers have discovered a new fossil of a massive flying reptile that could eat its prey whole according to Daily mail.

The fossil was found in the Transylvania region of Romania and is believed to be 70 million years old.

The fossil is of Hatzegopteryx: A reptile with a short, massive neck and a jaw that's about half a meter wide - large enough to swallow a small human or child.

Hatzegopteryx was a pterosaur - a flying reptile that existed at around the time of the dinosaurs.

Cats may be as intelligent as dogs, say scientists

The idea that dogs are more intelligent than cats has been called into question.

Scientists say cats are as good as dogs at certain memory tests, suggesting they may be just as smart according to BBC.

A study - involving 49 domestic cats - shows felines can recall memories of pleasant experiences, such as eating a favourite snack.

Dogs show this type of recollection - a unique memory of a specific event known as episodic memory.

Humans often consciously try to reconstruct past events that have taken place in their lives, such as what they ate for breakfast, their first day in a new job or a family wedding.

80-million-year-old dinosaur collagen confirmed

Utilizing the most rigorous testing methods to date, researchers have isolated additional collagen peptides from an 80-million-year-old Brachylophosaurus. The work lends further support to the idea that organic molecules can persist in specimens tens of millions of years longer than originally believed and has implications for our ability to study the fossixl record on the molecular level according to Science daily.

Elena Schroeter, postdoctoral researcher, and Mary Schweitzer, professor of biological sciences, wanted to confirm earlier findings of original dinosaur collagen first reported in 2009 from Brachylophosaurus canadensis, a type of hadrosaur, or duck-billed dinosaur, that roamed what is now Montana around 80 million years ago.

Hubble gazes into a black hole of puzzling lightness

The beautiful spiral galaxy visible in the center of the image is known as RX J1140.1+0307; a galaxy in the Virgo constellation imaged by Hubble Space Telescope, and it presents an interesting puzzle. At first glance, this galaxy appears to be a normal spiral galaxy, much like the Milky Way, but first appearances can be deceptive! According to Science daily.

The Milky Way galaxy, like most large galaxies, has a super massive black hole at its center, but some galaxies are centered on lighter, intermediate-mass black holes.
