Uterus as sentinel by Debbie Lee

Menstrual health research
Uterus as sentinel
Tampon-based study.

by Debbie Lee

Leveraging power in the menstrualome, NextGenJane (NGJ) is unlocking the data of monthly cycles.

* As a hyper-responsive organ that responds to external and internal stimuli, from stress to disease, the uterus is a data trove.

* Menstrual blood contains early indicators of health and disease that’s difficult to get any other way.

* Members of the NGJ community mail their tampons using a patented, specially-designed collection kit.

* A survey is the beginning of this anonymised conversation with NGJ.

* The menstrual cycle is a convenient way to sample the uterus and advance the science of uterine biology.

* As a longitudinal study of women’s menstruation, a more sophisticated, molecular understanding of gynecological health will inprove medical diagnostics.

* More precise options for treatment is expected to deliver genomic insights and improved outcomes for endometriosis, fibroids, and other gynecological conditions.

changing leaves by Nancie Zivetz-Gertler

mix in some sugar
and the red only deepens
the leaves are changing

by Nancie Zivetz-Gertler

A poet with no background in the actual science of trees , writing haiku often leads me to learn unexpected things!

I was working with the kigo “changing leaves” and wondered why the reds are so red, why so breathtaking….

Then I discovered anthocyanins!

Extract from ‘Why do leaves change color in the fall?’:

“Most of the year, these leaves are green because of the chlorophyll they use to absorb energy from sunlight during photosynthesis. The leaves convert the energy into sugars to feed the tree.

As the season changes, temperatures drop and days get shorter. Trees get less direct sunlight, and the chlorophyll in the leaves breaks down.

The lack of chlorophyll reveals yellow and orange pigments that were already in the leaves but masked during the warmer months. Darker red leaves are the result of a chemical change: Sugars that can get trapped in the leaves produce new pigments (called anthocyanins) that weren’t part of the leaf in the growing season. Some trees, like oaks and dogwoods, are likely to produce red leaves.

How much and how fast leaves transform varies by location on the globe. The best colors are produced when the weather is dry, sunny and cool. Places that are cloudy, damp or warm won’t see the same degree of changing color.”

Fantastical Flocks That Feast by Douglas J. Lanzo

red-billed quelea
millions of birds mirroring
shifting sands

by Douglas J. Lanzo

Highly social, fast-breeding, migratory birds, red-billed quelea swarm for protection while feeding on a huge volume of grass seeds.  Red quelea also avail themselves of grain-based farmer crops, leading them to refer derogatorily to the quelea as feathery locusts. 

Intensive cereal crop farming in Africa in recent years has augmented the already mind-numbing sizes of these swarms, which often number in the millions.  Some swarms have been estimated to surpass 40 million quelea.

Further reading:

To learn more about this incredible swarming behavior, check out the BBC One Planet Earth Plains documentary from 2009 at https://www.bbc.co.uk/programmes/p00381fg, which captured what is claimed to be the largest flock of birds ever caught on camera, which represents only a small fraction of the 1.5 billion quelea that swarm over Africa’s savannah during their breeding season.  Additional information on red-billed quelea can be found at: https://en.wikipedia.org/wiki/Red-billed_quelea.

Masterful Mimicry by Douglas J. Lanzo

desert drongo
mimicking meerkat sentries
to draw them off guard

by Douglas J. Lanzo

Fork-tailed desert drongo first win the trust of meerkats by sounding an alarm when a threatening hawk circles above their burrows.  Having won their trust, a wily drongo then betrays it by sounding a false alarm.  This sends meerkats into a tailspin, inducing them to flee to their burrows.  In the process , the duped meerkats abandon captured insects, lizards and scorpions, leaving the tasty critters behind for grateful drongo to claim.

Once the meerkats catch onto this trick, fork-tailed drongo elevate their deception to the next level.  From their desert perches, they imitate the warning bark or high-pitched squeal of the meerkat sentry itself, sending the clan into a panic.  The burrowing meerkats leave behind insects, scorpions and lizards for the breakfasting drongo, who swiftly swoop down from trees and shrubs to retrieve the coveted prey.

A toxic relationship by Mike Fainzilber

love hurts
the semen
and the venom

by Mike Fainzilber

Blue ringed octopi are small (they can fit in the palm of your hand), beautiful and extremely deadly – a venomous bite from the octopus nestled in your hand can kill you. Female octopi are larger than the males and will readily devour their smaller male partners during mating. The male solves this problem by biting into the female’s aorta,  injecting a large dose of venom that paralyzes the female for long enough for the male to complete mating and escape (1, 2).

A previously published SciKu by Debbie Lee describes application of a similar principle in insect biocontrol (3).

A Little Pain Goes a Long Way by Maryam Imogen Ghouth

Too much water drowns.
Yet, windstorms force trees to grow.
We must ache to rise.

by Maryam Imogen Ghouth

Plant physiology research shows that while water is essential for growth, excessive water can drown a plant by suffocating its roots. Conversely, mechanical stress from wind and storms can actually stimulate stronger, deeper root systems and sturdier trunks. This paradox mirrors human adversity—it can foster growth, while overprotection can hinder it.

Rejection by Maryam Imogen Ghouth

Friction gives us lift.
Foot meets ground and body moves—
resistance births flight.

by Maryam Imogen Ghouth

This haiku focuses on biomechanical motion. It draws on the principle that friction—between the foot and the earth—is what enables locomotion. According to Newton’s Third Law, movement arises from force met with equal and opposite reaction. This haiku serves as a reminder: when we encounter opposition, it isn’t always a sign to stop—it may be the very friction that lifts us forward.

Leafy Invaders – Eucalyptus by Sarah Das Gupta

Koalas eat leaves of the eucalyptus
famous in the land of kangaroos
but strangers in Spanish forests

by Sarah Das Gupta
Botanical name:Eucalypteae
Popular names:Gum tree, eucalypts, stringybarks
Family:Myrtaceae
Origin:Australia
Habitat:Full sun and well-drained soil

There are 700 species of the Eucalyptus, an aromatic tree native to Australia. The leaves are a bluish-green; the bark is often coloured and peeling. The tree is generally hardy in temperate zones. It can be pruned and cultivated in pots.

The Eucalyptus thrives in full sun and well-drained soil. It needs six hours of direct sunlight a day in spring and summer.

The roots can spread laterally up to one hundred feet and damage plumbing and pipes. Some species can grow up to 25 metres.

The Eucalyptus can have a negative effect on other trees. Its high transpiration rates lead to a decline in soil fertility. It is a host to the Eucalyptus gall wasp. The Honey-fungus feeds on the roots.

The tree does not add to bio-diversity and is allopathic in impact. It has been introduced into pine forests in Galicia, Northern Spain, to the detriment of other trees. Visiting the area earlier in the year, it was noticeable that the eucalyptus looked out of place in the pine woods both from a botanical and an aesthetic point of view. It is very flammable which is dangerous at a time of serious wild fires. There is some evidence that they are developing an ability to recover from the effects of fire. New varieties are being bred reaching only 3 to 5 metres.

Eucalyptus essential oil has a number of uses. It is a sinus-decongestant when inhaled in diluted form. It can relieve asthma either inhaled or using a diffuser. The oil can also be used for massage. Livestock often stand under Eucalyptus trees as it acts as an insect repellent. It can be a component in jet fuel, medical solvents, and dental hygiene. Undiluted, the oil is very strong. It should not be ingested and is toxic for dogs, cats and horses.

Fledgling Courage to Pierce the Pane by Douglas J. Lanzo

thirst for survival
drenched fledging great dusky swift
pierces waterfall

by Douglas J. Lanzo

This sciku was inspired by watching the “South America” episode of the BBC series Seven Worlds, One Planet narrated by David Attenborough.

It shows how great dusky swifts build nests protected by the waterfalls from hawks and other birds of prey, which nests get flooded from dam releases upriver of the spectacular Iguazu Falls (on the Iguaçu River). The torrential dam releases sometimes force the parent great dusky swifts to have to abandon their fledglings, who unless they can escape from the torrents and fly through a massive cascading curtain of water into the sunlight, will either starve or plummet to their deaths. The poem recognizes the courage and tenacity of the fledglings who attempt to breach this waterfall curtain and succeed in doing so.

Deceit Woven by an Orb Weaver by Douglas J. Lanzo

false beacon of light
flashing forest firefly
caught in spider web

by Douglas J. Lanzo

The orb-weaver spider is a master at weaving elaborate wheel-shaped webs that span across forest trees, capturing fireflies absorbed in mating rituals. Unfortunately for fireflies, the first firefly caught is not immediately killed, but rather just immobilized. That causes it to continue to flash, attracting more and more fireflies into the deadly spider web. And so the orb-weaver’s tale is woven…

Leafy Invaders – Bamboo by Sarah Das Gupta

Visions of exotic eastern haunts
of elegant Japanese gardens
a refugee in temperate regions

by Sarah Das Gupta
Botanical name:Bambusoideae
Popular names:Teddy Bear Bamboo, Sweet Dragon Bamboo, Zigzag Bamboo, etc.
Family:Poaceae (grass)
Origin:Asia-Pacific Region
Habitat:Sheltered, sunny position

Bamboo belongs to the sub-species Bambusoideae which is a member of the grass family. It has hollow, evergreen stems or culms. There are two types of root systems, ‘clumping’ or ‘running’. Bamboo needs a sheltered, sunny spot, with six to eight hours of indirect sunlight in spring and summer and consistent moisture. At least one of the many species is native to all regions of the world, except Europe and Canada. The word ‘bamboo’ is thought to originate in Malay or Kannada and passed on through Dutch or Portuguese colonists.

Currently, there are no laws restricting the cultivation of bamboo in the UK, other than that of not causing a ‘nuisance’ to neighbours.

Undoubtedly, this plant, in its many varieties, has something to offer to the gardener. It can create a micro climate while forming a windbreak or a privacy screen. In parts of Asia and southern Africa, it provides animal fodder.  Farmers use it as a mulch and, in many areas, it is a wildlife habitat. Fresh, new shoots are edible.

There are also drawbacks to the cultivation of bamboo. An individual bamboo culm lives up to ten years and is difficult to control or eradicate. Only the use of chemical herbicides or the physical removal of rhizomes will destroy unwanted plants. Some varieties can be aggressive and spread quickly. Buildings, pipes and drainage can be damaged. Bamboo can also be lethal to dogs.

Some species can grow to 46 meters in height and 36 centimetres in width. Species like the Japanese Giant Timber bamboo can grow 120 centimetres in 24 hours. The speed of growth and the fact that the plant thrives on marginal land means it is useful during this time of climate change. In southern Africa bamboo is used for building and food.

Many bamboo species have a life cycle of 40 to 80 years, with some blossoming at long intervals of 65 to 120 years. Fruit is produced, sometimes called ‘bamboo rice’. After this the plants die out.

Bamboo is also increasingly used for the manufacture of many and diverse artifacts including: paper, clothing, flooring, drinking straws, bowls and other containers, furniture

iceless improvisation by Douglas J. Lanzo

bobbing for apples
polar bear on off-shore rock
jaw-clamps belugas

by Douglas J. Lanzo

Deprived of seal hunting grounds due to melting ice, polar bears swim out to rocks and await high tide. These apex predators then pounce on unsuspecting belugas as they pass by their rocks, clamping down on their heads with skull-crushing jaws. But for this brutal improvization in hunting technique, some polar bears might otherwise starve. Receding Arctic ice greatly diminishes their ability to stalk seals surfacing through, or basking on, the ice.

Maugean Skate by Debbie Lee

A threatened species,
the Maugean Skate is tracked,
what price farmed salmon?

by Debbie Lee

In a report to the National Environmental Science Program, the Institute for Marine and Antarctic Studies (IMAS), of the University of Tasmania, highlights Marine and Coastal Hub research which uses eDNA to survey the endangered Maugean Skate in Bathurst Harbour on the south-western coast of Tasmania.

Despite extensive sampling, only minute traces of Maugean Skate DNA were detected. This is considered remnant traces of biological material, such as egg cases in sediment, or a few live individuals maximum. Thus it confirms that the vast majority, if not all, of the remaining Maugean Skate are in Macquarie Harbour.

This finding illustrates Maugean Skate vulnerability. It supports the need for continued research on the endangered Macquarie Harbour population, plus conservation action to ensure the persistence of a unique species of ray (Zearaja Maugeana).

A Pox on Dementia by James Penha

if you’re keen enough
to get the shingles vaccine—
you may stay that way

by James Penha

Shingles is a nasty inflammation that can strike those of us who had chicken pox. After suffering a bout of shingles, I decided last year to get vaccinated against it because the condition can recur. Apparently, this was a good decision in more ways than one since, according to a report in Science Daily, “A new analysis of a vaccination program in Wales found that the shingles vaccine appeared to lower new dementia diagnoses by 20%—more than any other known intervention.”

…no time to dream by Mike Fainzilber

basic training
the sleepless nights
of a dolphin mother

by Mike Fainzilber

This haiku deals with unique modes of sleep and sleep deprivation and relates to a study that showed that newborn dolphins and their mothers do not sleep at all for the first month of the newborn’s life.

The newborns require constant support and vigilance during this period, otherwise they may sink in the water and drown, hence no sleep at all for the dolphin mother! Human mothers with offspring in basic training in the military can probably relate to this…

This haiku is the second in a pair of poems on unique modes of sleep and sleep deprivation, the first being inspired by nesting penguins: ‘To sleep…’

To sleep… by Mike Fainzilber

micro-napping
the penguin
and the soldier

by Mike Fainzilber

This haiku deals with unique modes of sleep and sleep deprivation and relates to a study on nesting penguins in the wild, where the authors used remote monitoring techniques to determine sleep patterns. They found that wild chinstrap penguins sleep over 10,000 times a day, for an average of 4 seconds each time – totaling ~11 hours sleep per 24. This is an extreme case of microsleeps, interspersed by brief awake periods, and may help the penguins to guard their eggs during breeding season in the penguin colony. The parallels with the fitful short sleeps of a human soldier are highlighted in the haiku.

This haiku is the first in a pair of poems on unique modes of sleep and sleep deprivation, the second being inspired by dolphin mothers: ‘…no time to dream’.

Language of fungi by Debbie Lee

Language of fungi
Mycelium colony
Neuronal spiking

by Debbie Lee

The mycelium of a fungal colony may use electrical impulses to communicate, which could be considered a “language”. The impulses vary in amplitude, frequency, and duration, and can be grouped into “words”. Mycelium acts as an organic network of telephone lines, sending signals to different parts of the fungus. The impulses can be modified in response to different stimuli, similar to how neurons operate in a brain. The patterns of electrical impulses could be the basis of a fungal language. Different fungal species may have distinct electrical signaling patterns, suggesting a unique “language” for each species. The average word length in the fungal language may be similar to the average word length in some human languages.

In his paper “Language of fungi derived from their electrical spiking activity”, Andrew Adamatzky applies quantitative analysis of voltage fluctuations in fungal mycelia. The report concludes that the patterns of electrical fluctuations can be grouped into “words” analogous to those found in human languages. Adamatzky’s 2022 study groups spikes into words, thereby providing a linguistic and information complexity analysis of the fungal spiking activity. This confirms a secret language of mushrooms: How fungi use electricity to speak.

Matriarch by James Penha

when earth spun faster
Luca settled in the sea
and begat us all

by James Penha

Last July, researchers at Bristol University concluded that Luca (last universal common ancestor from which all life on Earth stems) lived 4.2 billion years ago—early enough in the planet’s existence to suggest that life might be an inevitability rather than an accident.

The Blood and the Run by Mike Fainzilber

flying dracula
bleeding to run
running to bleed

by Mike Fainzilber

This is a haiku about the stuff of nightmares – vampire bats. As we know, vampire bats feed on blood, and blood is low in carbohydrates and lipids that are the typical fuel for activities that require high energy. Flight is highly costly in energy, so how can it be fueled by blood alone? Certain blood-sucking insects can fuel their flight by direct metabolism of amino acids (the building blocks of proteins) in their blood meals, but this metabolic specialization was known only in very few insect species.

A team of biologists traveled from the University of Toronto to Belize to find out if vampire bats can do the same. The researchers took advantage of the fact that vampire bats are exceptionally good runners, and they use this to approach their prey along the ground. Bats were fed cow blood with labeled amino acids and the researchers then placed them on treadmills, monitoring tracer release in the bat’s breath as they ran on the treadmill.

The experiments clearly showed that vampire bats use amino acids as their main fuel source while running. Since running is a major hunting mode for this species, they literally bleed prey to run, and run to bleed…

Mandrake by Sarah Das Gupta

A screaming root
beneath the moon’s watery spears
black hound needed

by Sarah Das Gupta
Botanical name:Mandragora officinarum
Popular names:Satan’s Apple, Devil’s Turnip, Manroot, Circe’s Plant
Family:Solanaceae
Origin:Mediterranean, Middle East, North Africa.
Flower:Purple–yellow-green, bell-shaped corolla, five petals, flowers grow from rosette of  leaves.
Habitat:Stony waste ground, edge of woodland, coastal areas

The long taproot, shaped like a human form, was said to scream when pulled from the ground. Anyone hearing this would go mad. In Medieval times, it was believed the only way to harvest the plant was on a moonlit night and using a black dog with a cord attached to the plant to uproot it!

It was also believed that the mandrake first grew from the dripping ‘juices’ of a hanged man. This, by the medieval Doctrine of Signatures which taught that the shape and appearance of a plant linked it to parts of the human body, made the mandrake highly valued for specific ailments. However, the poisonous nature of the plant made its medicinal use difficult, as Harry Potter fans may know

The mandrake contains tropane alkaloids which give it narcotic, emetic, sedative and hallucinogenic properties. As early as the fourteenth century BC the plant is mentioned in cuneiform texts and subsequently in Arabic, Greek and Roman writing. It was said the root could be seen as a baby in form, albeit a rather ugly one. This gave rise to the belief that the plant helped childless women to conceive.

Mandrake roots were valuable and not surprisingly there were fraudsters at country fairs with oddly-shaped ‘mandrakes’ carved from turnip roots. It was even believed that these roots knew the sites of buried treasure. They would whisper the secret to their owner, if they trusted him. These beautiful lines from Shakespeare suggest Mandrake was still in use in the 16th century:

‘Give me to drink mandragora.
That I might sleep out the great gap of time
My Antony is away.’

William Shakespeare,
Anthony and Cleopatra, Act 1, Scene 1.

Monkshood by Sarah Das Gupta

imposing imperial purple
deadly to man, beast and bird
Shiva’s throat turned blue

by Sarah Das Gupta
Botanical name:Aconitum napellus (over 250 species)
Popular names:Aconite, Blue helmet, Blue rocket, Leopard’s bane, Monkshood, Wolfsbane
Family:Ranunculaceae
Origin:Mountain slopes of Europe eastward to the Himalayas.
Flower:Purple-blue (white, yellow), tall floral spires, mid-late summer.
Habitat:Northern Hemisphere, mountain meadows, partial shade, east or west facing.

Monkshood, so called because its hooded flowers resemble a monk’s cowl, is a hairless perennial of the buttercup family. Several species are cultivated, often at the back of herbaceous borders. Every part of the plant is poisonous and eating even a leaf can be fatal. It is best to wear gloves when handling and keep out of the reach of children or pets. Apparently, it tastes so repulsive that accidental poisoning seems unlikely.

Several unpleasant symptoms result from rubbing the plant into the skin, including numbness. Ingesting it results in stomach pain, dizziness, and heart problems. It is still used in medicines today but in very small quantities.

From ancient times, people have been aware of the dangers of this plant. The ancient Greeks associated it with Hades and it was believed to have sprung up from the saliva of the three-headed dog, Cerberus. The goddess, Athena, is said to have sprinkled the sap on the maiden Arachne, turning her into a spider! In Hinduism the plant is sacred to Lord Shiva who saved the Earth by drinking poison, which he stored in his throat, turning it blue. In European tradition, aconite is linked to Hecate which is why it was found at crossroads and gateways which were associated with her cult. Anglo-Saxon hunters covered the tips of their arrows with aconite when hunting wolves, hence the name wolfsbane.

Undersea Fireworks by Douglas J. Lanzo

firecrackers
a sperm whale dialogue
ignites in dark sea

by Douglas J. Lanzo

I was inspired to write this Sciku by reading an article in the July-August 2024 issue of Harvard Magazine entitled “Decoding the Deep” by Jonathan Shaw. I was struck by the tremendous energy in the short staccato bursts of sperm whale communication and by the intricacy in their communications, including what may be simultaneous speaking and listening in their species.

The article details the richness and wonder of the firecracker-evoking clicks of sperm whales and the billions of vocalizations the CETI project, with the help of machine learning, is ambitiously seeking to collect and decode.

Signaled Synchrony by Douglas J. Lanzo

diving in formation
sperm whale pod
upon one matriarch click

by Douglas J. Lanzo

I was inspired to write this Sciku by reading an article in Harvard Magazine entitled “Decoding the Deep” by Jonathan Shaw. It reinforced the beauty and intricacy of whale communications that had fascinated by watching ocean documentaries over the years.

The article details the complexity of the staccato clicking language of sperm whales and the billions of vocalizations the CETI project is seeking in order to decode their speech. However, I was struck that the first sperm whale word we have learned is the word to dive. Given that sperm whales travel in pods led by matriarchs and that a single click can be emitted at well over 200 decibels, I came up with this sciku to capture their magnificent synchrony of movement signaled by a single whale click.

It is amazing to think of the tremendous depths to which whales can descend (nearly 3,000 meters) at over 100 atmospheres in pressure and even more amazing to ponder the vocalizations of these wondrous creatures with the largest brains in the world.
