Creepy âsea monstersâ falling from sky in Alaska.
Š AP creepy sea monster
As if these scary-looking creatures werenât terrifying enough in the water, theyâre now falling out of the sky in Alaska. For real.
Locals in Fairbanks have been finding lampreys, foot-long eel-like fish with horrifying teeth, around the town after dropping out of the sky.
One was found in a shopâs car park, while another was found in someoneâs garden. Eww.
And why is this horror happening? We hear you cry. Well, itâs all thanks to the local birds, apparently.
According to Seattleâs CBS Local, the Alaska Department of Fish and Game explained what was happening on its Facebook page, writing: âGulls are picking them out of the Chena River with their bills and then dropping the squirming critters while in flight.
âArctic lampreys spawn in the Chena River, and live in the mud underwater as juveniles for several years. However, many lifelong Alaskans have never seen one of these fascinating fish up close because their body shape and feeding habits make them difficult to catch.â
They also posted more pictures of the creepy creatures. Look if you dare:

 Scientists probe mysterious wave of antelope deaths
By Rory Galloway
BBC Science writer
Around 120,000 Saiga antelope have died so far
Around half of the worldâs critically endangered Saiga antelope have died suddenly in Kazakhstan since 10 May.
An unknown environmental trigger is thought to have caused two types of normally benign bacteria found in the antelopesâ gut to turn deadly.
The animals die within hours of showing symptoms, which include depression, diarrhoea and frothing at the mouth.
Because it is calving season, entire herds of female antelope and their new-born calves have been wiped out.
âThey get into respiratory problems, they canât breathe easily. They stop eating and are extremely depressed; the mothers die and then the calves are very distressed and then they die maybe one or two days later,â said Richard Kock from the Royal Veterinary College in London.
Prof Kock spoke to the BBCâs Science in Action programme after joining an international team in Kazakhstan studying the causes of the die-off.
Conservation setback
The Saiga antelope is a species adapted to cope with the extremes of temperature found on the central Asian steppes of Kazakhstan. They are about the size of a large sheep and once roamed in their millions from Great Britain to northern China.
Populations have fallen repeatedly due to hunting, reaching a low of around 50,000 individuals after the fall of the Soviet Union. This rendered the species critically endangered.
Hunting brought Saiga numbers to a low of 50,000 in the 1990s
Conservationists have made great progress with Saiga in recent years, due to international efforts to reduce poaching and monitor their populations.
This die-off is a severe setback to the conservation effort because it has wiped out four of the six calving herds in the largest remaining â and best protected â âBetpak-dalaâ population, in central Kazakhstan.
Steffen Zuther, head of the Association for the Conservation of Biodiversity in Kazakhstan (ACBK), was monitoring calving in one of the herds containing thousands of affected animals.
âOver two days [in the herd I was studying] 80% of the calving population died,â he told the BBC.
The whole herd then died within two weeks.
Steffen Zuther has been monitoring herds of antelope in Kazakhstan
About 120,000 individual antelope have died, from a global population of approximately 250,000. Fortunately, mortality rates are now dropping, although the deaths continue in some populations.
âWhat weâre seeing is sort of a perfect storm of different factors,â Prof Kock explained.
Two different bacteria, pasteurelosis and clostridia, have been found in every dead animal studied. These bacteria are naturally found in the animalsâ respiratory and gut systems, so something must have reduced the immunity of the animals.
One possible trigger is climatic. This year a very cold winter was followed by a wet spring, and this may have affected the immune competence of the animals, making them more vulnerable to the bacteria.
This, or some other trigger, pushed the animals past a threshold at which the bacteria overcame Saiga immune defences and became deadly enough to transmit to their calves.

Because of its timing, the wave of deaths has claimed mothers and calves
âThereâs no infectious disease that can work like this,â said Prof Kock. He added that the wave of Saiga deaths was not unprecedented. â[This] die-off syndrome has occurred on a number of occasions.â
In 1984, 2010 and 2012 there were massive die-offs, but none of these claimed such a massive proportion of the population. âDoesnât make senseâ
Despite these huge losses, Saiga antelope are surprisingly well adapted to recover quickly from population crashes.
âIts strategy for survival is based on a high reproductive rate, so [the Saiga] produce triplets and have the highest foetal biomass of any mammal. Itâs built, in a sense, to recover from collapse,â Prof Kock said.
The Saigaâs natural habitat has dramatic temperature fluctuations. âIn a very severe winter⌠you could lose 90% of the population.â
But losing 100% percent of some populations within two weeks âdoesnât make any senseâ from a biological or evolutionary perspective, Prof Kock said.
There are five main populations of Saiga remaining in central Asia
Saiga antelope have been a conservation success story after recovering from their critical low in the 1990s. The animals now exist in five locations across central Asia, but all individuals affected by the sudden die-off are from the largest remaining Betpak-dala population in Kazakhstan.
This population consists of six major herds, of which four have been completely wiped out.
Steffen Zuther is going back into the field to investigate more remote populations. He hopes to identify what triggered this population collapse, so he can work to stop it happening again.
What Do Tree Rings Sound Like When Played Like A Record?
Playing tree rings
In the Dr Seusse books itâs the Lorax speaks for the trees, but what do they sound like when they speak for themselves?
Rings on a tree can give information about the age of the tree, as well as indicate environmental conditions such as rain levels, disease, and even forest fire. Light colored rings indicate quick growth, while darker rings indicate times when the tree did not grow as quickly. Slices of trees are not uniform, and they all tell a story about the treeâs history.
Bartholomäus Traubeck created equipment that would translate tree rings into music by playing them on a turntable. Rather than use a needle like a record, sensors gather information about the woodâs color and texture and use an algorithm that translates variations into piano notes. The breadth of variation between individual trees results in a individualized tune. The album, appropriately titled âYears,â features spruce, ash, oak, maple, alder, walnut, and beech trees. It is available to download now, though it will be available to purchase on vinyl in August. The end product of these arbor ârecordsâ is haunting and beautiful and you need to check it out.
The sea is big, scary and full of things that want to eat you.
If you ever find yourself in doubt as to whether or not to go in the water, it can be helpful to remember the sheer number of giant teeth, suckers and appendages-yet-unknown-to-science that live in it.
A spine-chilling, luminous, snakelike creature was recently captured in Taiwan by a man who was out fishing at a port in Penghu.
The fisherman, Wei Cheng Jian, caught the strange creature and posted a video of his find on Facebook in hopes of getting a few answers.
However, Jian, who seemed more than a bit nervous in the video, removed the clip from his Facebook page shortly afterwards â but not before the footage was copied, shared, and incited a little internet confusion.
In the video, the three-foot-long bright-green creature is seen slithering slowly across the dockâs concrete floor and shooting out a long pink tongue as if searching for a prey.
The seemingly alien-like critter sparked a huge debate online with persons from science fiction backgrounds to an expertise in the natural world throwing in their two-cents about the creatureâs origin.
And though an exact answer has not yet been determined, the stringy green mass is strongly believed to be a ribbon worm (or, Nemertea) â a carnivorous worm that comes in a variety of shapes, sizes, and colors.
Some species live on land or reside in freshwater â but many of them choose to stay in the sea and live burrowed in the sand. They can also grow to be as long as 60 meters.
Terrifying âsoul-sucking dementor waspâ turns unlucky victims into âZOMBIESâ
Dementor Wasp
This week, the World Wildlife Fund (WWF) reported that 139 new species were discovered in the Greater Mekong region last year, including a species of wasp that can turn a cockroach into a Zombie and eat it alive as it pleases.
The species making headlines is a wasp named after fictional, soul-sucking prison guards known in the Harry Potter universe as Dementors.
WWF describes the wasp as âsteal[ing] its preyâs free will with single sting before eating it alive,â and continues:
[Ampulex] dementor hunts cockroaches, injecting a venom into the mass of neurons on its preyâs belly that turns the roach into a passive zombie⌠the cockroach is still capable of movement, but is unable to direct its own body. Once the cockroach has lost control, the wasp drags its stupefied prey by the antennae to a safe shelter to devour it.
Once the cockroach has lost control, the wasp drags its stupefied prey by the antennae to a safe shelter to devour it.
Though the species is new, this group of wasps is not. Ampulex wasps are part of the Ampulicidae wasp species, known as cockroach wasps for their typical prey. This wasp, however, was named after Dementors as part of a group of researchersâ efforts to bring the public into the process of naming new species.
Hereâs the emerald cockroach wasp a cousin of the Dementor which does a similar thing.
The researchers, led by Michael Ohl, invited 300 museum visitors to choose from four possible names for the new species, and explained how each was connected to the wasp. Dementorââmagical beings, which can consume a personâs soul, leaving their victims as an empty but functional body without personality and emotionsââreigned supreme.

Ceres
The fascinating bright spots on the surface of the dwarf planet Ceres have come into sharper view.
What were initially thought to be just a couple of brilliant, closely spaced features at one location now turn out to be a clutch of many smaller dots.
The latest pictures were acquired by the US space agencyâs Dawn spacecraft on its first full science orbit since arriving at Ceres on 6 March.
The spots were seen from a distance of 13,600km.
Researchers on the mission concede they still have much to learn about the dotsâ true nature, but the new data is hardening their ideas.
âDawn scientists can now conclude that the intense brightness of these spots is due to the reflection of sunlight by highly reflective material on the surface, possibly ice,â said Chris Russell, who is the principal investigator on the mission.
With a diameter of 950km, Ceres is the largest object in the main asteroid belt between Mars and Jupiter.
Dawn will spend the coming months studying its geology and surface chemistry with a suite of cameras and remote-sensing instruments.
The intention is to get some insights into the processes that have sculpted the dwarf since its formation with the rest of the Solar System some 4.5 billion years year ago.
Having completed its first science orbit, Dawn is now heading downwards to get even closer to the body.
This second mapping campaign, which will commence on 6 June, will see Dawn moving just 4,400km from the surface.
Here are some strange sounds from outer space.
The noise is caused by electromagnetic vibrations. The sounds have been recorded by various NASA space craft using Plasma Wave antenna to record the vibrations.
Russia Orders Obama: TELL THE WORLD ABOUT ALIENS, Or We Will.
From Disclose.tv
Alien Chupacabra
February 11, 2015 â A stunning Ministry of Foreign Affairs (MFA) report on Prime Minister Medvedevâs agenda at the World Economic Forum (WEF) this week states that Russia will warn President Obama that the âtime has comeâ for the world to know the truth about aliens, and if the United States wonât participate in the announcement, the Kremlin will do so on its own.
The WEF (The Forum) is a Swiss non-profit foundation, based in Cologny, Geneva and describes itself as an independent international organization committed to improving the state of the world by engaging business, political, academic and other leaders of society to shape global, regional and industry agendas.
The Forum is best known for its annual meeting in Davos, a mountain resort in GraubĂźnden, in the eastern Alps region of Switzerland. The meeting brings together some 2,500 top business leaders, international political leaders, selected intellectuals and journalists to discuss the most pressing issues facing the world, including health and the environment.
Medvedev is scheduled to open this years Forum where as many as 50 heads of government, including Germanyâs Angela Merkel and Britainâs David Cameron, will attend the five-day meeting that begins on 23 January.
Critical to note about this years Forum is that the WEF, in their 2013 Executive Summary, scheduled for debate and discussion a number of items under their X Factors from Nature category, and which includes the âdiscovery of alien lifeâ of which they state: âProof of life elsewhere in the universe could have profound psychological implications for human belief systems.â
Equally critical to note is that Medvedev, after completing a 7 December 2012 on-camera interview with reporters in Moscow, continued to respond to reporters and made some off-air comments without realizing that his microphone was still on. He was then asked by one reporter if âthe president is handed secret files on aliens when he receives the briefcase needed to activate Russiaâs nuclear arsenal,â Medvedev responded:
âAlong with the briefcase with nuclear codes, the president of the country is given a special âtop secretâ folder. This folder in its entirety contains information about aliens who visited our planet⌠Along with this, you are given a report of the absolutely secret special service that exercises control over aliens on the territory of our country⌠More detailed information on this topic you can get from a well-known movie called Men In Black⌠I will not tell you how many of them are among us because it may cause panic.â
Western news sources reporting on Medvedevâs shocking reply about aliens stated that he was âjokingâ as he mentioned the movie Men In Black, which they wrongly assumed was a reference to the 1997 American sci-fi adventure comedy about two top secret agents battling aliens in the US.
Medvedev, however, wasnât referring to the American movie but was, instead, talking about the famous Russian movie documentary Men In Black which details many UFO and alien anomalies.
Where Western news sources quoted Medvedev as saying âMore detailed information on this topic you can get from a well-known movie called âMen In Black,ââ his actual answer was, âYou can receive more detailed information having watched the documentary film of the same name.â
The reason(s) for Western propaganda news outlets deliberately distorting Medvedevâs words become apparent after his shocking statement, and as evidenced in just one example of their so called reporting on this disclosure of alien life already being on our planet where the title of one such article was âRussian Prime Minister Dmitri Medvedev makes a crack about aliens, and conspiracists promptly lose their minds.â
If anyone is âlosing their mindsâ about aliens, it must be pointed out, it is certainly not Russia, but the Vatican, which in November 2009 announced it was âpreparing for extraterrestrial disclosureâ.
Equally, and apparently, âlosing their mindsâ are US government officials themselves, such as former Pentagon consultant Timothy Good, and author of Above Top Secret: The Worldwide U.F.O. Cover-Up, who in February 2012 stated that former President Dwight Eisenhower had three secret meetings with aliens who were âNordicâ in appearance and wherein a âPactâ was signed to keep their agenda on Earth secret.
With the recent discovery in the Russian city of Vladivostok of a 300-million-year-old UFO tooth-wheel, and scientists, astronauts and YouTube users reporting increasingly strange happenings on the moon, the European Space agency reporting their discovery of a 1,000 ancient river on Mars, and UK and Sri Lanka scientists saying they now have ârock solid proof of alien lifeâ after finding fossilized algae inside meteorite, the only ones who seem to be truly âlosing their mindsâ are the Western, especially American, propagandists who for decades have covered up one of the most important stories in all of human history that âwe are not alone.â
To if Medvedev will be able to convince the Obama regime to tell the truth about UFO and aliens at the WEF this week it is not in our knowing. What is in our knowing, though, is that with or without the US, the Kremlin will surely begin the process of telling the truth about that which we already know to be true.
Hereâs some interviews with people who claim to have been abducted by aliens.
Dark matter âghostsâ through galactic smash-ups
By Jonathan Webb
Science reporter, BBC News
Space
By observing multiple collisions between huge clusters of galaxies, scientists have witnessed dark matter coasting straight through the turmoil.
Dark matter is the mysterious, invisible stuff that makes up 85% of the matter in the cosmos â and these results rule out several theoretical models put forward to explain it.
This is because it barely interacts with anything at all, including the dark matter in the oncoming galaxies.
The work appears in Science magazine.
To conduct their study, astrophysicists looked at 72 smash-ups between galactic clusters, using two space telescopes: visible light was recorded by the Hubble Space Telescope, and X-rays by the Chandra Observatory.
Scouring multiple views of the collisions, the researchers tracked the movement of the three main components of galaxies: stars, clouds of gas, and dark matter.
The violently swirling clouds of gas are hot enough to glow with X-rays, which Chandra detects. And stars can be seen in regular, visible-light images from Hubble.
Dark matter is more difficult to âseeâ â but not impossible. Although it does not emit or absorb light, it does have gravity, and so it bends the path of light passing nearby. This warps our view of anything on the other side of it, in an effect called âgravitational lensingâ.
âLooking through dark matter is like looking through a bathroom window,â said Dr Richard Massey from Durham University, one of the studyâs authors. âAll the objects that you can see in the distance appear slightly distorted and warped.â
Images were used from the Hubble Space Telescope (illustrated here) and the Chandra X-Ray Observatory
Using this distortion allowed Dr Massey, with colleagues from the University of Edinburgh, University College London and Switzerlandâs Ecole Polytechnique Federale de Lausanne (EPFL), to âmapâ the dark matter in the clusters as they collided.
âSmash it and seeâ
Galaxy clusters are vast and contain huge amounts of dark matter, so when they collide â over billions of years â it offers a unique glimpse of how the stuff behaves.
âWe like these collisions because itâs exactly what weâd do in the lab,â Dr Massey told BBC News.
âIf you want to figure out what something is made out of, you knock it, or you throw it across the room and see where the bits go.â
In this case, the bits went straight through each other.
Unlike the gas clouds, which grind to a turbulent halt, and the stars, which mostly glide past each other, the ubiquitous dark matter passes through everything and emerges unscathed, like a ghost.
âIt seems not to interact with anything at all,â Dr Massey said.
Dr Tom Kitching, UCL Mullard Space Science Laboratory
Our new measurements of the self-interaction of dark matter are some of the best yet. But statistically speaking, the strongest result from this study is in fact the confirmation that dark matter really does exist in these galaxy clusters.
We measured three things: the position of stars, the position of mass, and the position of gas. If there was no dark matter, then all of the mass that isnât accounted for by the stars would be associated with the gas.
But we found an offset, which confirms that there is something in the clusters that is not gas, has mass, but that we cannot see: a dark matter. This detection is statistically very significant â corresponding to a probability of better than 99.99999999999% that dark matter exists in these clusters.
Sometimes I think dark matter is a terrible name. It was originally coined because the phenomenon does not emit or absorb light. But light is everywhere in the dark matter we have observed, passing within it and around it. Indeed, the lensing effect that we employed in our study uses the light from distant galaxies that has passed through dark matter.
So perhaps âtransparent matterâ or âclear matterâ are better names. My favourite alternative is âmateria incognitaâ (the unknown material). Maps used to be labelled âterra incognitaâ in areas that were unknown, and in a similar way we could be explicit about the unknown nature of this phenomenon.
However, thanks to studies like this one â and much more work planned for the coming years â our ignorance will one day end. Then we can finally give this âsomethingâ a proper name.
Earlier observations of the âBullet Clusterâ â a bust-up between two particularly big groups of galaxies, now in its final stages â had already demonstrated dark matterâs weird lack of interactions, including with itself.
But this new, major survey was able to deliver much more precision, concluding that there was even less interaction than the previous work allowed for.
âIf you bang your head against the wall, the electrostatic force between the molecules in your head and the ones in the wall cause a collision. This is what dark matter doesnât seem to feel,â Dr Massey explained.
Dark matter does âfeelâ gravity; those interactions are the reason we know it is there, and the reason it is bound up in the galactic collisions to begin with. But the lack of almost any other interaction makes it even more mysterious than before.
The late-stage collision of the Bullet Cluster yielded previous observations of dark matter
âIn all of these collisions that weâve seen, it just seems to go straight through. And now weâve seen loads more of them, we would have been able to detect any deceleration of this dark matter, if it had interacted in the ways that most theories predict,â Dr Massey said.
So although some theories remain, many can now be ruled out. This includes the idea that dark matter is some sort of âdarkâ version of ordinary matter, made of âdark atomsâ. It must be more outlandish than that, Dr Massey said.
âBasically, weâre saying: Back to the drawing board! Letâs come up with some more ideas.â
Space has some really interesting stuff going on. Hereâs a clip featuring some of the sounds of outer space.
Giant pythons have âhoming instinctâ
By James Morgan
Science reporter, BBC News
This enormous Burmese python burst trying to swallow an alligator in Florida in 2005
Giant Burmese pythons have map and compass senses which help them travel âhomeâ over vast distances, scientists have been surprised to discover.
Pythons captured and relocated in Floridaâs Everglades â where they are an invasive species â returned 23 miles (36km) to their original start point.
It is the first evidence that snakes may share a similar magnetic compass to other reptiles, such as sea turtles.
The findings are published in the Royal Society journal Biology Letters.
The Burmese python (Python bivittatus) is one of the largest snakes in the world. The biggest specimen ever caught measured more than 17ft (5m) and weighed 164lb (74kg).
The snakes coil around their prey and suffocate it â and have been known to swallow animals as large as alligators.
Although native to South East Asia, they have become established in Floridaâs Everglades National Park â where they have been blamed for a staggering decline of mammals.
To study how these invasive predators migrate and spread, researchers captured 12 snakes and fitted them with GPS radiotransmitters.
Half were released where they were captured, but the other six were transported to other suitable habitats in the Everglades 13-23 miles (21-36 km) away.
Using aircraft to track their movements, the researchers were stunned by how quickly the snakes travelled homeward.
The pythons could navigate by the Sun, the stars, or by a magnetic compass
Five of the six returned within 5km of their original capture location â and their movement was faster than the control snakes.
âWe were very surprised,â said lead author Shannon Pittman, of Davidson College, North Carolina.
âWe anticipated the pythons would develop new home ranges where they were released. We didnât expect them to orient back to their capture locations.
âThis is evidence that Burmese pythons are capable of homing on a scale previously undocumented in any snake species.â
The experiment suggests the snakes have both a map sense (to determine their position in relation to home) and a compass sense (to guide their movement home).
Researchers say the map could be magnetic, like sea turtles, while the compass could be guided by the stars, olfactory (smell) cues, or by polarised sunlight â all of which have been shown to be used by reptiles.
âOther snakes likely do share this ability with pythons. But our understanding is limited by a dearth of research on the subject,â Ms Pittman told BBC News.
Some previous studies found that smaller snakes â sea kraits and garter snakes â can home over short distances, but not large constrictors.
âIâm impressed, but Iâm not surprised â this verifies what many of us in the field have been seeing for years,â said Dr Stephen Secor of the University of Alabama, who researches Burmese python physiology.
âReptiles know where theyâre going â itâs not just random. Theyâre familiar with their home range.
âAnd I suspect that, if pythons can do this, all snakes can do it â rattlesnakes, vipers, the lot.â
Dr Stephen Secor says the pythons are actually gentle, docile creatures
Keeping in familiar territory may help snakes to find prey and mates, and the homing sense may allow them to return to their territory after exploratory forays, Ms Pittman said.
âWe know that snakes tend to come back to some of the same sites throughout their lives â such as overwintering locations or refuges,â she told BBC News.
Understanding how invasive pythons migrate could help control their spread in Florida, she suggested.
But Dr Secor said the threat to the Everglades had been overstated: âSome people want to sell it as an ecological disaster. Itâs really not.
âBurmese pythons canât ever move beyond the Everglades. Itâs too cold. The minute it freezes, it kills them,â he told BBC News.
âTheyâre actually very docile, gentle snakes. People who donât like them donât know a lot about them. Theyâre pretty amazing animals and we can learn a lot from them.â
And the first lesson we can learn from their homing ability, said Dr Secor, is âdonât pick reptiles upâ.
âPeople see turtles crossing the road and try to move them to safety. But if you take them away, theyâre just going to try and come back. You are doing more harm than good.
âLikewise with snakes â people find them in their yard, drive them off and dump them a mile down road. Then, three days later, the snake comes back.
âI hear these stories frequently: âIt came back! The same snake!â And Iâm always kind of sceptical. Is it really the same snake? Or just another one that looks similar?
âBut maybe these people were right all along. The snake really did come back.â
Hereâs one big Australian python. The cameraman thought it was dead.
Itâs quite simple really. You take the number 1 and add it to itself which gives you 2. You then add the 2 to the 1 which =3. then 3+2 = 5. 5+3= 8 and so on like this. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811, âŚ
A bit freaky.
But it gets freakier.
The Fibonacci numbers are Natureâs numbering system. They appear everywhere in Nature, from the leaf
Fibonacci in nature
arrangement in plants, to the pattern of the florets of a flower, the bracts of a pinecone, or the scales of a pineapple. The Fibonacci numbers are therefore applicable to the growth of every living thing, including a single cell, a grain of wheat, a hive of bees, and even all of mankind.
Plants do not know about this sequence â they just grow in the most efficient ways. Many plants show the Fibonacci numbers in the arrangement of the leaves around the stem. Some pine cones and fir cones also show the numbers, as do daisies and sunflowers. Sunflowers can contain the number 89, or even 144. Many other plants, such as succulents, also show the numbers. Some coniferous trees show these numbers in the bumps on their trunks. And palm trees show the numbers in the rings on their trunks.
Fibonacci in plants
Why do these arrangements occur? In the case of leaf arrangement, or phyllotaxis, some of the cases may be related to maximizing the space for each leaf, or the average amount of light falling on each one. Even a tiny advantage would come to dominate, over many generations. In the case of close-packed leaves in cabbages and succulents the correct arrangement may be crucial for availability of space.
In the seeming randomness of the natural world, we can find many instances of mathematical order involving the Fibonacci numbers themselves and the closely related âGoldenâ elements.
Fibonacci in Plants
Phyllotaxis is the study of the ordered position of leaves on a stem. The leaves on this plant are staggered in a spiral pattern to permit optimum exposure to sunlight. If we apply the Golden Ratio to a circle we can see how it is that this plant exhibits Fibonacci qualities. Click on the picture to see a more detailed illustration of leaf arrangements.
By dividing a circle into Golden proportions, where the ratio of the arc length are equal to the Golden Ratio, we find the angle of the arcs to be 137.5 degrees. In fact, this is the angle at which adjacent leaves are positioned around the stem. This phenomenon is observed in many types of plants.
Fibonacci in trees
The number of petals in a flower consistently follows the Fibonacci sequence. Famous examples include the lily, which has three petals, buttercups, which have five (pictured at left), the chicoryâs 21, the daisyâs 34, and so on. Phi appears in petals on account of the ideal packing arrangement as selected by Darwinian processes; each petal is placed at 0.618034 per turn (out of a 360° circle) allowing for the best possible exposure to sunlight and other factors.
The head of a flower is also subject to Fibonaccian processes. Typically, seeds are produced at the center, and then migrate towards the outside to fill all the space. Sunflowers provide a great example of the
Sun flower seeds
Here are just a few plants that have their leaves and settles arranged according to Fibonacci numbers
Not surprisingly, spiral galaxies also follow the familiar Fibonacci pattern. The Milky Way has several spiral arms, each of them a logarithmic spiral of about 12 degrees. As an interesting aside, spiral galaxies appear to defy Newtonian physics. As early as 1925, astronomers realized that, since the angular speed of rotation of the galactic disk varies with distance from the center, the radial arms should become curved as galaxies rotate. Subsequently, after a few rotations, spiral arms should start to wind around a galaxy. But they donât â hence the so-called winding problem. The stars on the outside, it would seem, move at a velocity higher than expected â a unique trait of the cosmos that helps preserve its shape.

US âŚ..
Faces, both human and nonhuman, abound with examples of the Golden Ratio. The mouth and nose are each positioned at golden sections of the distance between the eyes and the bottom of the chin. Similar proportions can been seen from the side, and even the eye and ear itself (which follows along a spiral).
Itâs worth noting that every personâs body is different, but that averages across populations tend towards phi. It has also been said that the more closely our proportions adhere to phi, the more âattractiveâ those traits are perceived. As an example, the most âbeautifulâ smiles are those in which central incisors are 1.618 wider than the lateral incisors, which are 1.618 wider than canines, and so on. Itâs quite possible that, from an evo-psych perspective, that we are primed to like physical forms that adhere to the golden ratio â a potential indicator of reproductive fitness and health.
Looking at the length of our fingers, each section â from the tip of the base to the wrist â is larger than the preceding one by roughly the ratio of phi.
Even our bodies exhibit proportions that are consistent with Fibonacci numbers. For example, the measurement from the navel to the floor and the top of the head to the navel is the golden ratio. Animals
Animals
Animal bodies exhibit similar tendencies, including dolphins (the eye, fins and tail all fall at Golden Sections), starfish, sand dollars, sea urchins, ants, and honey bees.
Honey Bee
Honey bees follow Fibonacci in other interesting ways. The most profound example is by dividing the number of females in a colony by the number of males (females always outnumber males). The answer is typically something very close to 1.618. In addition, the family tree of honey bees also follows the familiar pattern. Males have one parent (a female), whereas females have two (a female and male). Thus, when it comes to the family tree, males have 2, 3, 5, and 8 grandparents, great-grandparents, gr-gr-grandparents, and gr-gr-gr-grandparents respectively. Following the same pattern, females have 2, 3, 5, 8, 13, and so on. And as noted, bee physiology also follows along the Golden Curve rather nicely.

The Golden rectangle has been known since antiquity as one having a pleasing shape, and is frequently found in art and architecture as a rectangular shape that seems ârightâ to the eye. It is mentioned in Euclidâs Elements and was known to artists and philosophers such as Leonardo da Vinci.
One of the interesting properties of the golden rectangle is that if you cut off a square section whose side is equal to the shortest side, the piece that remains is also a golden rectangle.
In the figure below, the yellow rectangle is in the same proportion as the original larger rectangle after the gray square is cut off.Both the rectangles ABCD and PBCQ are golden rectangles.
