For years scientists have been studying the impact of different geophysical fields on the earthquakes occurrence. It has been assumed that the fields, generated due to the solar activity, earth flows fluctuations, the Earth`s speed of rotation and even the launch of magnetohydrodynamic generators affect the strained state of the earth`s crust, these fields `pumping` additional energy into the crust. Normally the aroused earthquakes are recorded several days after the provoking key event.

Because living organisms contain millions of different molecules, identifying or separating any single one of these from their natural environment in order to carry out research work or perform diagnoses is quite like looking for a needle in a haystack. A number of molecular separation technologies are of course available, and are used by laboratories on a daily basis, but they are often unwieldy and costly. Scientists the world over are therefore attempting to develop a new generation of analytic de

Martian atmosphere churns harder in south making north wetter.

Scientists have figured out why it’s wet up north – on Mars. A new computer simulation of the martian atmosphere suggests that the planet’s geography causes differences in atmospheric circulation within the northern and southern hemispheres. These differences dump more water on the martian north pole, where it adds to the seasonal ice-cap.

Knee-high relative of Triceratops unearthed.

The fearsome horns and bony neck plates of Triceratops have scared generations of kids. Now fossil finds reveal that its predecessor was a little more huggable: it was a dog-sized creature with a beak.

Triceratops is the most famous member of the late ceratopsians, which were rhinoceros-like dinosaurs with horns. Little is known about the early evolution of this large and varied group of plant-eaters because their fo

Ethiopian fossil suggests early humans were one big family.

A one-million-year-old skull unearthed in Ethiopia hints that our long-extinct cousins Homo erectus were a varied and widespread bunch, much like today’s humans. The find may undermine previous claims that H. erectus was in fact made up of two different species. Homo erectus , which means ’upright man’, appeared about 1.8 million years ago. Because of its posture and large brain, it is regarded as t

A University of Plymouth lecturer and his PhD student are putting Plymouth on the world map for research in a specialist field of marine biology: the importance of seagrass meadows.

Seagrass can grow prolifically in outer estuarine areas and is the only flowering plant fully adapted for life in the marine environment. As well as being home to a wide variety of animal life including fish such as sea horses, its dense beds offer some protection against wave buffeting and the ensuing coastal e
