Evolution tells us we might be the only intelligent life in the universe

Nick Longrich, University of Bath

Are we alone in the universe? It comes down to whether intelligence is a probable outcome of natural selection or an improbable fluke. By definition, probable events occur frequently, improbable events occur rarely – or once. Our evolutionary history shows that many key adaptations – not just intelligence, but complex animals, complex cells, photosynthesis, and life itself – were unique, one-off events, and therefore highly improbable. Our evolution may have been like winning the lottery … only far less likely.

Animals are disappearing from forests, with grave consequences for the fight against climate breakdown – new research

It’s tempting to think that our forests would be fine if we could simply stop trees being felled or burnt. But forests – particularly tropical ones – are more than just trees. They’re also the animals that skulk and swoop among them.

Worryingly, these furry and feathered companions are rapidly disappearing – and our new research indicates that this will have grave repercussions for the role forests play in combating climate breakdown.

Benefits of Renewable Energy Sources: Is Renewable Energy the Key to Fighting Climate Change?

There is no way of protecting the climate without drastically mitigating fossil fuel combustion. Nearly half of CO2 pollution comes from power plants burning fossil fuels. But there’s a way to turn things around. Renewable energy cuts down carbon pollution and has a much lower impact on the environment.

Sputnik 1: the 62nd anniversary of humanity’s space exploration

On October 4, 1957, the first artificial satellite. Sputnik 1, was launched by the Soviet Union. Thus, began the space age. It orbited the Earth until January 4, 1958. Sputnik made 1440 orbits and traveled about 70 million kilometers (43 million miles).

The successful launch shocked the world, according to NASA, and giving the former Soviet Union the distinction of putting the first human-made object into space. Its “unanticipated” success precipitated the Sputnik crisis in the United States and triggered the Space Race, a part of the Cold War.

The word ‘Sputnik’ originally meant ‘fellow traveler,’ but has become synonymous with ‘satellite’ in modern Russian.

Today is the 62nd anniversary of Sputnik 1’s launch. Russian space agency Roscosmos has published a video on Twitter to celebrate.
