what the snp want, though, is it? i mean, they voted for a no deal brexit so under their plans, it would have been even harder. and as the music industry themselves have said, what they need now is clarity, not recriminations. and that, mr speaker, is what the british government are working to provide. the culture secretary will be hosting a roundtable discussion with musicians on this matter. i do not know if the six pistols have been invited. and, thank you very much. a new study has helped solve the puzzle of how butterflies take to the air. for decades, scientists thought their large wings were aerodynamically inefficient. but they ve now worked out that butterflies cup their wings when taking off, forming an air pocket that pushes the insect forward helping it to escape predators. laura foster reports. it was this moment that has left scientists all aflutter. high speed cameras confirming
if you look at their wings, you can see they are very large and broad compared to the size of their body and aren t considered to be very aerodynamic. but this to make of clapping and cupping now appears to have given them an evolutionary advantage. thinking is this technique developed by the humble butterfly could be applied to modern tech allergy to make drones and underwater vehicles faster, travel further and last for longer. laura foster, bbc news. just a reminder that later today in washington, it will be the inauguration, handover of powerfrom president biden. the time now in washington, just after half past midnight. we are in the final 12 hours of the trump presidency. a changeover at 12 noon exactly local time. changeover at 12 noon exactly localtime. 0f changeover at 12 noon exactly local time. of course, very different inauguration one we have ever seen or be extensive
it was this moment that has left scientists all aflutter. i speed cameras confirming what had been suspected for half a century, that butterflies don t just flap their win wings but clap them together. there are taxable wings bending to form a cup pocket about. when they collapse, this trust is even stronger and more efficient. it s only now thanks to modern technology and a swedish wind tunnel that we can see it. , . swedish wind tunnel that we can see it. v .. . swedish wind tunnel that we can see it. , ., . ., ., see it. it s a challenge to work with see it. it s a challenge to work with any see it. it s a challenge to work with any living - see it. it s a challenge to | work with any living flying animal but with butterflies it s maybe even more because they are smaller, they are fast in their behaviour, difficult to predict their behaviour and also when flying them in a wind tunnel, it s difficult to get them to behave as you want to, when you want to and also to fly whe

seen here for 400 years. severe storms, including ciara and dennis, caused widespread damage in february, such as here on the river dart in devon. but spring sprung sunny and dry, breaking records in may, as we came to terms with life locked down. always first thing in the morning, i used to live about half past five, quarter to six, to go on my walk. so, yes, i always got out. we were out quite a lot in our local area, doing it a lot more than we would normally. so we have been out and about quite a lot, haven t we? post summer conditions, produced spectacular autumn colours, an antidote to the second lockdown. however, we were allowed to spend more time outdoors than during the first. there was, though, an increasing amount of grey, as another disease thrived in 2020. ash dieback caused widespread damage to woodlands. but, a great yearfor apples.
