Science News – Solar Storms Due to Hit Earth

This weekend the Earth is due to be hit by a pair of solar storms that might affect radio and satellite communication. But how and why does this happen?

What Does Solar Mean?

Anything that is related to a sun is commonly described as being solar. Our sun is a typical medium-sized yellow star which is about 5 billion years old. Its surface temperature is about 5,500°C, but even that isn’t as hot as its superheated centre. Some parts of the sun’s surface are cooler, with a temperature of between 2,700–4,200°C, and these appear darker when viewed through specialised telescopes. These cooler patches are caused by fluctuations in the sun’s magnetism and are called sun spots.

SCIENCE NEWS – Discovery of An Underground Ocean

Earth’s Underground Ocean

In 1864 the French author, Jules Verne, published his novel “Journey To The Interior of the Earth”. In this book 3 men explore volcanic tunnels that lead miles beneath the Earth’s surface, and have a number of strange encounters along the way. One of these is the discovery of a massive ocean, deep underground. Now, 150 years later, it seems that Monsieur Verne’s imagination may have been more accurate than he knew.

An enormous reservoir of water, roughly 3 times bigger than all of the Earth’s oceans put together, has been detected 400 miles below the surface. The water is trapped inside a layer of blue rock called ringwoodite, in the layer of hot rock between the Earth’s core and its surface) that is known as the mantle.

Pride of Place – The World of the Lion

Lions are felines, which means that they are members of the same wider family as cats. Indeed, they are frequently referred to as “large cats” or something similar.

They live on plains and savanna in Africa and India, where the sun beats down on the grassland so that it fades, withers and turns yellow – just the colour of a lion, which helps to camouflage it, so that it can blend in with its surroundings and stay hidden.

SCIENCE NEWS – What is Dengue Fever and Could Genetically-Modified Mosquitoes Prevent It?

Dengue (pronounced den-gee) fever affects between 50-100 million people each year, with around 25,000 people dying from the disease. It’s most common in south America and parts of Africa, and is also known as breakbone fever because it causes such intense pain in the bones. Dengue fever is a virus that’s spread by mosquitoes, and there is no vaccine or effective drug treatment to prevent or cure it.
