Journeys into the Unknown

Journeys into the Unknown

February 24, 2015

What is exploration, and what distinguishes it from travel, discovery, or adventure? Stewart Weaver’s survey of the history of exploration, published by Oxford University Press, offers a compelling set of answers. Along the way, Weaver identifies what defines exploration during each era and places these historic achievements in the largest possible global context: that of the natural history of the earth itself.

Star Buzzed Our Solar System during Human Prehistory

Star Buzzed Our Solar System during Human Prehistory

February 21, 2015

The red dwarf star, which has a mass about 8% that of the Sun and is orbited by a ‘brown dwarf’ companion, was discovered in 2013 in images recorded by NASA’s Wide-field Infrared Survey Explorer (WISE) mission. It is relatively nearby, at about 6 parsecs (19.6 light years) away.

In the paper, astronomers led by Eric Mamajek at the University of Rochester, New York, say they are 98% certain that Scholz’s star travelled through what is known as the “outer Oort Cloud” – a region at the edge of the Solar System filled with trillions of comets a mile or more across.

Alien star missed us by less than a light-year, scientists say

February 18, 2015

Astronomers say a red dwarf star and its brown dwarf companion passed within a light-year of our own sun 70,000 years ago, moving through the comets in the outer reaches of the Oort Cloud that surrounds our solar system.

Dr Eric Mamajek, an astronomer at the University of Rochester who led the study, said that it is unlikely the star would have caused much disturbance to the scattered icy comets that orbit the outermost reaches of our solar system.

A recently discovered dim star likely passed some 70,000 years ago through our solar system’s distant cloud of comets known as the Oort Cloud. No other star is known to have ever approached our solar system this closely.

Although most materials slightly expand when heated, there is a new class of rubber-like material that not only self-stretches upon cooling; it reverts back to its original shape when heated, all without physical manipulation.

Five ways to improve your brainpower

Five ways to improve your brainpower

February 15, 2015

It used to be thought that the brain was hardwired and that, unlike other organs, it could not repair itself or restore lost functions once damaged or diseased. Now we know that, in fact, the brain is neuroplastic – that activity and mental experience can be used to change the structure of the connections within it

Curious monkeys trade ‘prize’ for information

February 13, 2015

Monkeys have such robust curiosity that they are willing to give up a surprisingly large portion of a potential prize in order to quickly find out if they selected the winning option at a game of chance, new research has found.
