Dinosaurs ‘too successful for their own good’

Dinosaurs spread across the world shows they may have been a victim of their own success, according to study.

UK researchers believe they were already in decline before the killer asteroid hit because they had occupied every habitat on Earth, according to BBC.

From their roots in South America, the dinosaurs migrated "in a frenzy of movement to cover the planet".

Toward end of Ice Age, human beings witnessed fires larger than dinosaur killers

On a ho-hum day some 12,800 years ago, the Earth had emerged from another ice age. Things were warming up, and the glaciers had retreated, according to Science Daily.

Out of nowhere, the sky was lit with fireballs. This was followed by shock waves.

Fires rushed across the landscape, and dust clogged the sky, cutting off the sunlight. As the climate rapidly cooled, plants died, food sources were snuffed out, and the glaciers advanced again. Ocean currents shifted, setting the climate into a colder, almost "ice age" state that lasted an additional thousand years.

Animals worldwide are giving up their ‘wild ways’ and sticking closer to home as cities

Animals worldwide are giving up their 'wild ways' and sticking closer to home as a result of human activity, according to Daily Mail.

That's according to a new study that found mammals living in areas with high human activity move up to three times less far than animals in areas isolated from people.

This pattern persists globally, from forest elephants to foxes and red deer, affecting species both big and small.

Experts say that human settlements, roads and fences break up their natural habitat and block the natural migration of mammals, allowing for the easy spread of deadly diseases.

Mosquitoes remember human smells, but also swats

Your grandmother's insistence that you receive more bug bites because you're 'sweeter' may not be that far-fetched after all, according to Science daily.

 The study, shows that mosquitoes can rapidly learn and remember the smells of hosts and that dopamine is a key mediator of this process. Mosquitoes use this information and incorporate it with other stimuli to develop preferences for a particular vertebrate host species, and, within that population, certain individuals.

Plastic pollution is ‘killing endangered corals reefs’

Plastic pollution in the world's oceans are threatening the already endangered coral reefs with disease, a new study has warned, according to Daily Mail. 

More than 11 billion plastics are currently putting coral reefs at risk of becoming diseased and destroying the habitat of millions of fish species, the research said.

The study conducted estimates that this level will increase by 40 per cent within seven years.    

'That equates to an estimated 15.7 billion plastic items on coral reefs by 2025,' said Joleah Lamb, who led the study. 

Scientists are still uncertain why plastics are so dangerous for coral but saw how the exposure to plastics caused the organisms stress through light deprivation, toxin release and the absence of oxygen.
