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.

How the darkness and the cold killed the dinosaurs

Sixty six million years ago, the sudden extinction of the dinosaurs started the ascent of the mammals, ultimately resulting in humankind's reign on Earth. Climate scientists now reconstructed how tiny droplets of sulfuric acid formed high up in the air after the well-known impact of a large asteroid and blocking the sunlight for several years, had a profound influence on life on Earth. Plants died, and death spread through the food web. Previous theories focused on the shorter-lived dust ejected by the impact. The new computer simulations show that the droplets resulted in long-lasting cooling, a likely contributor to the death of land-living dinosaurs. An additional kill mechanism might have been a vigorous mixing of the oceans, caused by the surface cooling, severely disturbing marine ecosystems according to Science daily.

Has the mystery of the Earth's core been solved?

It has baffled scientists for decades - exactly what is the mystery 'third element' at the Earth's core?

Now, a team has the answer - and says its silicon according to Daily mail.

Researchers have been searching to solve the mystery at the centre of our planet for decades after discovering there is something other than iron and nickel there

Japanese scientists believe they have established the identity of a 'missing element' within the Earth's core.
