Unique views of Earth afforded by a pioneering twin ESA radar satellite flight has brought an extra dimension to maps of Canada’s newest territory, the results winning praise from the Canadian government.

Nunavut is the latest and also largest territory of Canada: located up in the frozen northeast, Nunavut has a population of only around 29 300 but an area the size of Western Europe. The Canadian government is currently refining and updating its geographic information for the

Ocean temperatures might have risen even higher during the last century if it weren’t for volcanoes that spewed ashes and aerosols into the upper atmosphere, researchers have found. The eruptions also offset a large percentage of sea level rise caused by human activity.

Using 12 new state-of-the-art climate models, the researchers found that ocean warming and sea level rise in the 20th century were substantially reduced by the 1883 eruption of the Krakatoa volcano in Indones

A unifying physics principle that describes design in nature predicts, in surprisingly straightforward fashion, the basic features of global circulation and climate, according to researchers at Duke University’s Pratt School of Engineering and the University of Evora in Portugal. They said the new approach to climate may have important implications for forecasting environmental change.

The researchers found that the “constructal theory” can predict the global circulation that

Ohio State University planetary scientists have found the remains of ancient lunar impacts that may have helped create the surface feature commonly called the “man in the moon.”

Their study suggests that a large object hit the far side of the moon and sent a shock wave through the moon’s core and all the way to the Earth-facing side. The crust recoiled — and the moon bears the scars from that encounter even today.

The finding holds implications for lunar prospectin

Sharks, people have electric connection in their lineage

Sharks are known for their almost uncanny ability to detect electrical signals while hunting and navigating.

Now researchers have traced the origin of those electrosensory powers to the same type of embryonic cells that gives rise to many head and facial features in humans.

The discovery, reported by University of Florida scientists in the current edition of Evolution & Development, identifies neural

Introduced foxes throw a wrench in the food web

Indirect effects of predators

In an extensive study, researchers from the University of Montana, University of California – Santa Cruz, and the University of California – Davis have shown that a top predator strongly affected plants and animals at the bottom of an island food web by eating organisms that transport nutrients between ecosystems. “An introduced predator alters Aleutian island plant communities by thw
