Comet 67P full of surprises: Growing fractures, collapsing cliffs and rolling boulders

Images indicate the surface of comet 67P/Churyumov-Gerasimenko was a very active place during its most recent trip through the solar system, says a new study.

The images show the comet's surface is full of growing fractures, collapsing cliffs and massive rolling boulders. Moving material buried some features on the comet's surface and exhumed others.

"As comets approach the sun, they go into overdrive and exhibit spectacular changes on their surface," said Ramy El-Maarry, study leader. which gave us the chance to look at a comet in ultra-high resolution for more than two years."

Oldest croc eggs discovered in dinosaur nest

The oldest crocodilian eggs known to science have been discovered in the cliffs of western Portugal .According to BBC.

They are so well preserved that they give an insight into the "mother croc" that laid them 152 million years ago.

The prehistoric crocodile ancestor would have spanned two metres, based on the size of the larger eggs, say palaeontologists.

Crocodilians arose some 200 million years ago, when they prowled the land with early dinosaurs.

Today, they are found throughout the world and are successful predators.

The moon is on a collision course with EARTH

The moon is currently spinning away from Earth at a rate of around 3.8 centimetres a year.

But experts believe that in the future this could change, and the two bodies could one day be on a collision course.

If the moon and Earth collide, the energy released in the merging would melt the Earth into a magma ocean.

Thankfully, the catastrophic event is not forecast to occur for some 65 billion years.

The prediction comes from Dr Jason Barnes, a planetary scientist.

Dr Barnes said: 'The final end-state of tidal evolution in the Earth-moon system will indeed be the inspiral of the moon and its subsequent collision and accretion onto Earth.'

Evolution of bipedalism in ancient dinosaur ancestors

Paleontologists have developed a new theory to explain why the ancient ancestors of dinosaurs stopped moving about on all fours and rose up on just their two hind legs.

Bipedalism in dinosaurs was inherited from ancient and much smaller proto-dinosaurs. The trick to this evolution is in their tails explains Scott Persons, postdoctoral fellow and lead author on the paper.

"The tails of proto-dinosaurs had big, leg-powering muscles," says Persons. "Having this muscle mass provided the strength and power required for early dinosaurs to stand on and move with their two back feet. We see a similar effect in many modern lizards that rise up and run bipedally."

Komodo blood found to have 'superantibacterial' properties

They’re the largest lizards in the world, with deadly saliva that’s loaded with at least 57 species of bacteria to bring down their prey.

And, according to new research, the blood of Komodo dragons could be the key to developing new drugs in the fight against antibiotic-resistant superbugs.

The team used a method known as ‘bioprospecting,’ revealing antimicrobial protein fragments in their blood that protects them against infections.

In the study, researchers investigated whether they could isolate substances known as cationic antimicrobial peptides from Komodo dragon blood – massive lizards the dwell on five small islands in Indonesia.

These CAMP substances are an essential part of the innate immune system, and the team had previously done this with alligator blood.
