A decade is a lifetime in internet terms. Back in 2007, Twitter was still in its infancy and Pinterest, Snapchat and Instagram didn’t even exist. We did have YouTube, Reddit, Amazon, the BBC, Apple and IMDb, however, and you can see exactly how they looked back then by visiting Ten Years Ago. Click any of the 15 logos and you can go straight to that company’s decade-old homepage, courtesy of the Internet Archive’s Wayback Machine ( web.archive.org ). Ten years ago  You can marvel at how cluttered YouTube looked and how cramped the pre-iPlayer BBC site (above) was. You’ll also see Apple showing off the first iPhone and an Amazon site that makes no mention of the Kindle – the groundbreaking e-reader wasn’t launched until November. All the content linked to on the site is refreshed each day.

The following are   NASA's plan if an asteroid is heading to Earth  Step 1: A text message would be sent to a team of 12 scientists.  Step 2: The scientist immediately start tracing the asteroid's path  Step 3:  They measure the size of the object and predict the time of impact  Step 4: They confirm with authorities whether the impact is unavoidable.  Step 5: A public statement would then be issued. Photo by  Bryan Goff  on  Unsplash Then NASA and emergency agencies how best to protect the Earth. They have simulated this experiment many times and come up with a few defensive options. They include firing lasers into the asteroid. Crashing a spacecraft into an approaching asteroid is another possibility. As is detonating a bomb next to an incoming object. There is no risk at the moment though. NASA can't detect any asteroid currently heading towards us. No large object is likely to strike for at...

Twitter recently extended the number of characters you can use in a tweet from 140 to 280,but sometimes you need even more room to make your point. One way to do this is to create a thread by continuing to reply to your own tweet until you’ve got everything off your chest. The main problem with this, however,is that other people replying to your tweets will interrupt the sequence, making your train of thought difficult to follow. To help,Twitter has introduced an official ‘threads’feature which keeps these tweets together,thereby making them easier to read as a whole. It has done this by adding a plus(+) button when ever you start a new tweet. Selecting this opens up another tweet-composing box, allowing you to carry on typing. When your each the end of that box, you can select+again and continue. Once you’re ready, simply press Tweet All and each post will be uploaded at the same time. This cuts out the hassle of reading a tweet and having to wait while the pe...

Experiments on the ISS have shown that young spruce tree seedlings do grow in microgravity, but they don’t look quite the same. The seedlings grow faster, and the pine needles don’t point downward so much. DNA analysis shows that several plant genes are more active in space, but we’re still waiting to find out the long-term effects on larger plants. Plants in space  are  plants  grown in  outer space  typically in a weightless but pressurized controlled environment in specific space gardens. [ In the context of human spaceflight, they can be consumed as food and/or provide a refreshing atmosphere.Plants can metabolize carbon dioxide in the air to produce valuable oxygen, and can help control cabin humidity. Growing plants in space may provide a psychological benefit to human spaceflight crews. The first challenge in growing plants in space is how to get plants to grow without gravity.This runs into difficulties regarding the effects of gravity on ...

Dam-building is synonymous with beavers, the ultimate aquatic engineers. Using branches from trees they have felled, these large rodents dam lakes to create moat-like ponds of still water where they construct islands known as ‘conical lodges’ out of timber, mud and rocks. The body of water surrounding the lodges provides protection from predators – resident beavers enter and exit their sophisticated homes incognito via waterfilled tunnels leading from the lodges to the pond. The largest lodge, found in Alberta, Canada, measures over 500m in length – though, contrary to a widely circulated myth, it is not visible from space! In deep or fast-moving water areas, beavers simply excavate into river banks and set up home there instead. Relates search terms: beaver dam alberta visible space They fell trees by gnawing through their trunks, then use the branches to dam streams. The dams create a pond, in the middle of which the beaver family constructs an island made of more branch...
