Biophiles ( lovers of life , to save you googling ) around the world may relish the sights , smells and vocalize that nature provides us , but many of us probably take for granted just how deeply some aspects of the natural cosmos have impact our culture and society throughout account .
To showcase some of the weird and wonderful ways nature has act upon the human raceway , the LondonNatural History Museumhas teamed up withBBC Radio 4to produce a fantastic series for your learning pleasure . IFLSciencehas been pick at some of the museum ’s brilliant brains to give you a snipping of some of the amazing case to come , and here they are :
How Brambles Help Forensic Investigations
part off on a rather dispirited topic , but did you know that brambles , those bristly shrubs that bring to us delicious blackberries and raspberries , can be used to help murder enquiries or suspicious expiry compositor’s case ? Yep . Provided , of course , that the body stop up out of doors , these scrambling vines can aid determine how long it ’s been there , as they have a tendency to “ grow in areas where people do spoiled thing to other mass , like railway system English or shrub lands,”Dr . Mark Spencer , British and Irish Herbarium senior curator , told IFLScience .
“ If , for instance , someone is murdered or die , and their remains are n’t light upon relatively quickly , they can be shoot within the landscape painting quite quick by plants . ” And if the pinched remains of the remains are still there a few long time on , brambles and other vegetation growing in the area can provide a useful calibrator to assess how long someone has been in the landscape , he total . A more traditional way to name a body , which could then assist appointment it , would be to expend teething , but over clip these can become damaged and sometimes teeth are absent altogether .
So how do scientists apply these shrubs ? bramble are extremely unionised plants ; on average , an individual plant will get off out one or two arching vegetative growths every year , increase the sizing and territory of the bramble . The next year , these stem will again bring forth side shoots , and it is this repetitive annual increment pattern that can help inform police detective of how long a dead body has been there . So if a organic structure is underneath or intersperse among brambles , the interplay between the number of shank and the clay can serve as a useful index number for scientist .
This monetary value - efficient technique therefore helps the police narrow down engagement , but it is not used in isolation . Rather , scientist will take information from whole plant communities — brambles just happen to be widespread in the UK .

Willy Wonka ’s Never - Fading Paint , Thanks to Butterflies
Nature provide us with some amazing colors , from brilliant blues and fiery reds to emerald greens and passionate pinks . But not all of these are the result of pigments ; some are the result of the fundamental interaction between light and microscopic surface nanostructures . These so - called geomorphologic colour tend to be brighter and more vivid than those that rise up from pigmentation , and let in the shimmer shade we see on butterfly stroke wing and some bird feathers .

away from the dazzling dish geomorphological colour can produce , why are scientist concerned in it ? unmistakably , the NHM’sProfessor Andrew Parkertells IFLSciencethat some 50 - million - year - old insects that exhibit structural coloration have keep their iridescence , leading scientists to think that if they can replicate it , they could produce dark products like paint that wo n’t fade .
“ If you pick up the precept behind nature ’s colors you’re able to begin to produce any colouring material you want — something promising , flashy , or even something that can change color reckon on the angle you consider it from , ” allege Parker .
To describe the secret behind the shimmer wing of butterfly , Parker ’s team first took cells from the part of a chrysalis that go on to become a wing and start culture them in petri lulu . By observing how the scales constitute in the lab , the scientist can see how the tiny structure that produce vividness develop over time , with the overall end of emulate that process . The close intersection would be tiny chip , etch with structures that bring on colors of desire , that will be mix in with a pellucid metier .
Interestingly , the butterfly scales grow under ambient temperatures and blue pressures , but when scientists endeavor to make these dainty structures themselves , high-pitched temperature and pressures are ask . However , if scientists can nail the suite of term that cells require in nature , then they may be capable to launch the mental process without the motive for huge amounts of energy , or the toxic mix of chemical unremarkably necessitate to produce paint . And as an supply bonus , paint made using this proficiency would also biodegrade faster than traditional paints , Parker says .

How insect Have Influenced Technology
It ’s not just butterflies that scientist are keen to get wind from ; a bantam , base - look beetle found scurrying across southern Africa ’s parch Namib Desert is helping scientists render water to community of interests in want .
Although a moist fog squander across this desert ’s sandlike dune , the bantam piss droplets contained within are n’t heavy enough to descend to the solid ground as rain , thus most thirsty brute wo n’t profit from it . But theNamib beetlesports a unique , jolty cuticle with both hydrophobic ( body of water - hating ) and hydrophilic ( weewee - loving ) point that act as a “ seeding decimal point , ” instantly develop droplets until they are large and heavy enough to roll towards the insect ’s mouthpiece — with the avail of a little headstand — and quench its thirst .

Parker ’s team has been endeavoring to copy this little bug so as to produce a simple , murkiness - harvesting net that could bestow water to both distant villages and hospitals place in desiccated areas . Working with the Massachusetts Institute of Technology , they have come up with a gaudy and simple material that can be printed using special hydrophilic inks on a hydrophobic surface , or vice versa , Parker enjoin IFLScience . Tests are currently underway in Chile ’s Atacama Desert , and it ’s already proving to be a achiever .
But these are n’t the only two pies Parker has his fingers in : His team is also re-create the anti - reflector design found on a 45 - million - year - old fly front center , which sports a special grating that prevents light reflecting from the aerofoil . Using the oculus as a basis for design , they have manage to produce sticky plastic sheets that can be adhered to solar panel , which result in an telling 10 % addition in energy seizure due to the reduction in reflection .
How Historical Bird Egg Collections Help scientist Monitor Environmental Changes
The NHM is gallant to be home to over 200,000 grasp of eggs , all of which derive with entropy on when and where they were found and to which mintage they go . This mega - archive has been built up over the past 250 year and , with more than 5,000 species , represents well over 50 % of the world ’s bird mintage .
But these do n’t just sit there looking pretty ; they ’re a “ 3D biologic library , quick to be investigated if a question arises,”Douglas Russell , NHM senior conservator of birds , tells IFLScience . So what kind of inquiry are we talking about ? Around half a century ago , British naturalistDerek Ratcliffebegan to use this collection for his pioneering study on the effects of certain pesticides , like DDT , on birds of quarry .
After noticing that peregrines and other mintage often had broken egg in their nests and abnormally small hold , Ratcliffe began probe the compendium of egg shell . He discovered that those forgather after the late 1940s had experienced thinning , a time that coincided with the introduction of DDT . Others began replicate his oeuvre in other area , and the evidence for the function of DDT in shell thinning became so convincing , as highlighted in the graph below , that pressing to ban these chemicals eventually led to their progressive phase out over the next 25 years .
D. Ratcliffe , 1970 .
Even though we have learn our moral about DDT and other so - called organo - chloride pesticide , thanks to this pioneering work , scientists today can still use this ever - growing collection to suffice other questions , for example how clime change strike breeding trends . Although they ca n’t separate ushowsomething is do these changes , Russell says that they can act as a incentive to understand the drive personnel . “ It ’s the beginning of a story , not the end , ” he adds .

From beldam to Harry Potter : Myths and Medicines of Mandrakes
Mandrakeshave been used medicinally for centuries , but these plant also have a lot of mythology colligate with them . If you ’re a fan ofHarry Potter , you may recall them being used in a Herbology class in which the students had to repot them using earmuff to forbid their deathly screams from being try . This floor is really take root in traditional belief about these plant , Dr. Sandy Knapp , virtue research worker of the NHM ’s Life Sciences Plants Division , tell IFLScience .

These plants come out in sixteenth - 100 ( Age of Enlightenment ) herbals , used medicinally for all form of thing , such as sedative drug or anesthetics . They were thereforehighly sought afterin their native Mediterranean home ground and effort were required to protect them from thievery , which is thought to have put up to one of the main myths associated with them .
It was believed that the wide mandrake solution were inhabited by a demon , likely also fuel by their freakish resemblance to a human figure , which would possess and kill whoever root out them . This require some heedful gardening : for remove them from the ground , you had to cut into around them and then tie your dog to the origin , which would then run off and pull out the plant ( plain the dog was impervious to the devil … ) .

Mandrakes belong to to the nightshade family , which contains many staples that we eat — such as tomato plant and brinjal — but also slightly less edible things like pernicious nightshade and tobacco . Some members of this folk bring forth toxic , ring structure compounds called tropane alkaloids that can bepotent psychedelic drug . They can be engage through mucous membrane on the body and often bestow the adept of flying , which is why they have been associated with witches ’ broomsticks . Many 15th - century painting render beldam gallivanting around on their Scots heather , bare , and it was write that this is how they would go for the dry land up plants to their soundbox , permit the chemicals to inebriate up through their … areas … Lovely .
So there you go , a rightfully divers accumulation of examples of how the natural world has work the society we live in .
