Researchers estimate ancient temperatures using data from climate proxy records, i.e., indirect methods to measure temperature through natural archives, such as coral skeletons, tree rings, glacial ice cores, and so on. For example, the...

Bose Einstein condensate is considered the fifth state of matter - its obtained when gas particles are cooled to almost absolute zero temperature. To generate the Bose-Einstein condensate, the first step is to obtain a cloud of gas; a...

The enormous challenge of building a probe capable of travelling over 1 billion kilometres to reach Saturn's moon, Titan. Physics - Universe - Learning Points. Huygens probe was designed by the European Space Agency at a cost of £400...

Large-scale nuclear fusion is one of the ultimate goals of science which has yet to be achieved. How does nuclear fusion work and is a future likely in which we can reproduce the power of a star on Earth? Earth Science - Earth's...

Earth's climate has changed naturally over millions of years. Could the current cycle of warming simply be part of this natural cycle? Earth Science - Human Impacts - Learning Points. The Medieval Warm Period occurred 1000 years ago....

Without the greenhouse effect, our planet would be too cold to inhabit, but it's currently a major cause of global warming. What is the greenhouse effect, and why is it such a conundrum? Earth Science - Human Impacts - Learning Points....

Learn how scientists overcame huge challenges to land a probe on Saturn's moon, and why Titan is of special interest to life on Earth. Physics - Universe - Learning Points. The Cassini-Huygens probe took seven years to travel over 1...

From camels to lizards, how animals and plants survive in some of the hottest and driest habitats on Earth - the hot deserts. Biology - Adaptation And Evolution - Learning Points. Organisms survive harsh environments by physical and...

We examine the effects of different temperatures and chemicals on the heart rate of Daphnia. A microscope is used to let us see the Daphnia\u2019s heart and establish the heart rate under normal conditions. The heart...

We demonstrate denaturing by adding the enzyme trypsin to photographic film. Strips of photographic film are added to trypsin solution at different temperatures to determine the optimum conditions for the enzyme. In the right conditions...

Scientists have found microbes frozen deep in the Antarctic ice sheets, in conditions very similar to the red planet's surface. Could life exist on Mars, in suspended animation? Physics - Universe - Learning Points. In 2001, a frozen...

How climatologists use ice cores, cylindrical cones of ice drilled from glaciers, to reveal Earth's historical cycles of climate change. Earth Science - Human Impacts - Learning Points. The Earth has natural, long cycles of climate. The...
