SpaceX - making Orbit cheaper
...because I for one would prefer to go up in a certified 'new' rocket.
Would you trust a 2nd hand parachute? (One previous owner, slight blood-staining)

You do realise that cold, small stars burn for a lot longer? Or not so much burn as smoulder and eventually cool. They're lifetimes could be measured by the trillion years, not the 10 or so billion our little yellow dwarf star can look forward to.
More likely is that the first minor bump will reveal that the fleshy meatbag was driving to fast or on their mobile. The self-driving cars will obey the road rules and auto-clype any fleshy's actions which contravene regulations. This could have a major impact on road safety once we realise we have to stick to our own rules. I for one welcome our zealous rule militating driving overlords!
I've been doing a lot of research on Youtube and actually the Earth is flat. Clearly this re-measurement has omitted this fact.
On a side note, having been up Ben Nevis more than a few times, I actually conclude that the Earth is mostly Uphill! Given a grant I could conduct more experiments somewhere sunny.
Surely with a radius 1.6 of Earth's, its volume is nearer 8 times that of Earth. And guessing a similar average density gives a Surface Gravity of around 3.3G.
Hmm, reaches for calculator and old dusty Astrophysics book...
Methinks to call it Earth 2.0 they've taken the lower limits of their measurements to produce the most Earthlike qualities. Unfortunately, they've ditched the overlarge, molten Iron core of Earth to reduce the average density. (Our little planet is the avg. densest body on our solar system bar the occasional asteroid made of pure platinum)
And what was the 'name' of the proto-Earth before the collision that went on to form the Earth and Moon? Maybe us commentards could have a poll? (It is thought that Theia gave a large amount of core-stuff to proto-Earth and left a lot of mantle/crust stuff in orbit, hence our oversized core and large moon)
On reading the BBC's poor telling I came to The Reg in hope of a more fulfilling story, which will in turn make me search out other more-sciencey websites, like wikipedia, but alas my search continues...
'conceal them from predators, such as dolphin'
or if these new fish-fangled LEDs were to be used on bicycles...
'reveal then to predators, such as buses'
If any of you have ever driven (or cycled) along dark roads and come across a cyclist using powerful 'offroad lights' you'll have noticed that brighter, more efficient LEDs are sorely needed.
