(Conversation) King Solomon may have gained some of his famed wisdom from an unlikely source – ants.

According to a Jewish legend, Solomon conversed with a clever ant queen that confronted his pride, making quite an impression on the Israelite king. In the biblical book of Proverbs (6:6-8), Solomon shares this advice with his son: “Look to the ant, thou sluggard, consider her ways and be wise. Which having no guide, overseer, or ruler, provideth her meat in the summer, and gathereth her food in the harvest.”

While I can’t claim any familial connection to King Solomon, despite sharing his name, I’ve long admired the wisdom of ants and have spent over 20 years studying their ecology, evolution and behaviors. While the notion that ants may offer lessons for humans has certainly been around for a while, there may be new wisdom to gain from what scientists have learned about their biology.

Lessons from ant agriculture

As a researcher, I’m especially intrigued by fungus-growing ants, a group of 248 species that cultivate fungi as their main source of food. They include 79 species of leafcutter ants, which grow their fungal gardens with freshly cut leaves they carry into their enormous underground nests. I’ve excavated hundreds of leafcutter ant nests from Texas to Argentina as part of the scientific effort to understand how these ants coevolved with their fungal crops.

Much like human farmers, each species of fungus-growing ant is very particular about the type of crops they cultivate. Most varieties descend from a type of fungus that the ancestors of fungus-growing ants began growing some 55 million to 65 million years ago. Some of these fungi became domesticated and are now unable to survive on their own without their insect farmers, much like some human crops such as maize.

Ant farmers face many of the same challenges human farmers do, including the threat of pests. A parasite called Escovopsis can devastate ant gardens, causing the ants to starve. Likewise in human agriculture, pest outbreaks have contributed to disasters like the Irish Potato Famine, the 1970 corn blight and the current threat to bananas.

Since the 1950s, human agriculture has become industrialized and relies on monoculture, or growing large amounts of the same variety of crop in a single place. Yet monoculture makes crops more vulnerable to pests because it is easier to destroy an entire field of genetically identical plants than a more diverse one.

Industrial agriculture has looked to chemical pesticides as a partial solution, turning agricultural pest management into a billion-dollar industry. The trouble with this approach is that pests can evolve new ways to get around pesticides faster than researchers can develop more effective chemicals. It’s an arms race – and the pests have the upper hand.Ants also grow their crops in monoculture and at a similar scale – after all, a leafcutter ant nest can be home to 5 million ants, all of which feed on the fungi in their underground gardens. They, too, use a pesticide to control Escovopsis and other pests.

Yet, their approach to pesticide use differs from humans’ in one important way. Ant pesticides are produced by bacteria they allow to grow in their nests, and in some cases even on their bodies. Keeping bacteria as a living culture allows the microbes to adapt in real time to evolutionary changes in the pests. In the arms race between pests and farmers, farming ants have discovered that live bacteria can serve as pharmaceutical factories that can keep up with ever-changing pests.

Whereas recent developments in agricultural pest management have focused on genetically engineering crop plants to produce their own pesticides, the lesson from 55 million years of ant agriculture is to leverage living microorganisms to make useful products. Researchers are currently experimenting with applying live bacteria to crop plants to determine if they are effective at producing pesticides that can evolve in real time along with pests.

Improving transportation

Ants can also offer practical lessons in the realm of transportation.

Ants are notoriously good at quickly locating food, whether it’s a dead insect on a forest floor or some crumbs in your kitchen. They do this by leaving a trail of pheromones – chemicals with a distinctive smell ants use to guide their nest mates to food. The shortest route to a destination will accumulate the most pheromone because more ants will have traveled back and forth along it in a given amount of time.

In the 1990s, computer scientists developed a class of algorithmsmodeled after ant behavior that are very effective at finding the shortest path between two or more locations. Like with real ants, the shortest route to a destination will accumulate the most virtual pheromone because more virtual ants will have traveled along it in a given amount of time. Engineers have used this simple but effective approach to design telecommunication networks and map delivery routes.

Not only are ants good at finding the shortest route from their nests to a source of food, thousands of ants are capable of traveling along these routes without causing traffic jams. I recently began collaborating with physicist Oscar Andrey Herrera-Sancho to study how leafcutter ants maintain such a steady flow along their foraging paths without the slowdowns typical of crowded human sidewalks and highways.

We are using cameras to track how each individual ant responds to artificial obstacles placed on their foraging trails. Our hope is that by getting a better understanding of the rules ants use to respond to both obstacles and the movement of other ants, we can develop algorithms that can eventually help program self-driving cars that never get stuck in traffic.

Look to the ant

To be fair, there are plenty of ways ants are far from perfect role models. After all, some ant species are known for indiscriminate killing, and others for enslaving babies.But the fact is that ants remind us of ourselves – or the way we might like to imagine ourselves – in many ways. They live in complex societies with division of labor. They cooperate to raise their young. And they accomplish remarkable engineering feats– like building structures with air funnels that can house millions – all without blueprints or a leader. Did I mention their societies are run entirely by females?

There is still a lot to learn about ants. For example, researchers still don’t fully understand how an ant larva develops into either a queen – a female with wings that can live for 20 years and lay millions of eggs – or a worker – a wingless, often sterile female that lives for less than a year and performs all the other jobs in the colony. What’s more, scientists are constantly discovering new species – 167 new ant species were described in 2021 alone, bringing the total to more than 15,980.By considering ants and their many fascinating ways, there’s plenty of wisdom to be gained.

New US sanctions on ICC, a fillip to worldwide political repression

US Secretary of State Marco Rubio’s warning to the International Criminal Court (ICC) was stark: ‘Either the ICC will end its threats, or we will end the ICC.’ It followed US central administration accusations that the court was unfairly targeting Americans on the basis of trumped-up war crimes charges.

However, a new plethora of sanctions has been clamped on the ICC by the US, which in turn has spurred accusations by sections of the world that the latter has unleashed an ‘assault’ on the international legal order.

What some of the sanctions would mean for the ICC was outlined by Rubio: ‘We will ban transactions with this rogue court, cutting off their resources and crippling their ability to operate against us.’

The ICC has shown consistency of purpose over the years. Despite some operational constraints it has indicted a large number of political strongmen from around the world, accused of war crimes and other governance excesses that come under its purview. Two such recent figures are: Russian President Vladimir Putin and Israeli Prime Minister Benjamin Netanyahu.

Rather than enjoy a mere nominal presence in the world community, the ICC has proved its effectiveness by detaining and bringing to justice scores of VIP politicians and others of their ilk who have been found guilty of human rights abuses and kindred excesses that come within the terms of reference of the ICC.

Accordingly, the international justice system would be stymied considerably as a result of the ICC being dis-empowered, particularly financially. Needless to say, potential and real perpetrators of the species of crime coming under the jurisdiction of the ICC would stand to gain most from such anarchic tendencies. That is, political repression globally would be enabled to enjoy a new lease of life.

A detailing of the types of crime coming under the purview of the ICC provides an idea of what it would cost the international community if the ICC’s operations are gravely hampered. They are mainly: genocide, war crimes, crimes against humanity and the crime of aggression.

That is, the part of the world to be worst affected would be the global South, since the latter is awash with the mentioned crimes. Needless to say, a chronically-disaffected South will sooner rather than later undermine the well being of the world dangerously. The world is already being put through these paces.

At the time of writing, ‘illegal migrants’ from the South, for example, are aggravating many a Western economy’s woes, besides creating for them acute law and order issues. The fact that these migrants’ presence goes on to become a virtual test of the migrant receiving states’ ability to forge domestic social inclusion in the face of jingoistic protests by mainly white supremacist groups is evidence of the latter. As is known, the US, to take just one example, has been up against this crisis for quite a while.

Accordingly, it will be in the best interests of the West if ‘illegal’ migrant arrivals on their shores are stemmed. If the socio-political and economic problems assailing the South are effectively managed through North-South collaborative, ‘trouble-shooting’ efforts the causes leading to ‘illegal’ migration and connected issues could be resolved at source as it were. For, it is the aggravation of the South’s material questions that lays the basis for the emergence of repressive and anti-democratic regimes in the hemisphere.

Until such time that the aforementioned issues in North-South relations are visited afresh and addressed urgently, a vibrantly functioning ICC would be needed. For, the latter would prove a deterrent to Southern political and military strongmen, highly prone to power abuse and like excesses, from coming into being in the wake of the South’s chronic material woes and the wars and conflicts that result from them.

It stands to reason then that the US would be acting in its own interests by enabling the ICC to perpetuate its mandate without hindrance. For a crop of issues that impinges negatively on internal law and order would be defused.

Meanwhile, there needs to be a meeting of minds among the rest of the West to put back in place a North-South dialogue process aimed at reducing some of the economic pressures that are weighing on the South.

Since economics usually drives politics it will be in the interests of the world community to scrutinizingly re-visit North-South issues of the past and put in place economic relief packages for Southern publics that would enable them to tide over their material hardships rather than permit the latter to aggravate into social disaffection and eventually armed militancy. It is the latter juncture that paves the way for the emergence of authoritarian rulers in the South who then go on to be a blight on their publics.

Accordingly, the Southern-based global development thinking of the past that envisaged a more equitable world economic order needs to be seen as an urgent need. That is, NAM’s international development paradigms need to be resuscitated to the extent possible.

It is unlikely that rightist governments of the West, such as the current Republican administration in the US, would find these projects feasible, but democratic states of Europe, led by perhaps the UK, are likely to think otherwise. For it would not be beneficial for the democratic world to be having on their hands repressive governments in the South who would be gravitating towards the major military and economic actors of the South, such as Iran and North Korea, who tend to be in constant power struggles with the West.

However, until such time that the mentioned, pro-people initiatives are given serious thought the ICC would need to be enabled by the international community to be in place comfortably and carry on with its mandate of bringing repressive rulers to book. Besides the ICC should pave the way for the peoples of the developing world to enjoy some substantial respite from the political repression and even terror which tend to be their lot.

Meanwhile, the wars of West Asia are relentlessly aggravating the economic hardships of people everywhere, driving the point home to enlightened sections that there is no alternative to peacemaking. A challenge is to convert the US under President Trump to this line of thinking.

This week, I give you five simple, time-tested homemade remedies that help reduce the appearance of blemishes, control excess shine and leave your skin feeling softer and smoother.

The Honey and Lemon Brightening Dab:

For stubborn blemish marks, this is a classic. Mix one teaspoon of pure bee honey with three to four drops of fresh lemon juice. Apply gently, only on the affected spots, and leave for 10 minutes before rinsing with lukewarm water. While honey soothes and softens, lemon helps to brighten naturally. Use twice a week in the evening.

Besan and Rose Water Oil-Control Pack:

An ideal remedy to combat shine, especially on the T-zone. Take two teaspoons of besan (gram flour) and mix with sufficient rose water to form a smooth paste. Add a pinch of turmeric for its antiseptic goodness. Apply evenly, keep for 15 minutes and wash off. It absorbs excess oil without over-drying, leaving a beautiful matte finish.

Aloe Vera and Cucumber Ice Soother:

Blend fresh aloe vera gel with the juice of a grated cucumber and freeze the mixture in an ice tray. Each morning, wrap one cube in a soft muslin cloth and gently rub over a cleansed face for 30 seconds. It calms, tightens pores and imparts a baby-soft smoothness.

Oatmeal and Curd Gentle Polish:

Roughness and old blemish marks need gentle exfoliation. Combine one tablespoon of finely powdered oatmeal with one tablespoon of fresh curd (yoghurt). Massage very gently, in circular motions, for one minute, leave for five minutes and rinse. It removes dead cells and unveils softer, clearer skin.

Multani Mitti and Green Tea Magic Mask:

Brew some green tea and allow it to cool completely. Mix one and a half teaspoons of Multani Mitti (Fuller’s Earth) with the tea water to make a fine paste. Apply for 10 to 12 minutes – do not let it dry and crack completely – and wash off. It draws out impurities, fades blemishes and bestows a fresh, shine-free glow.

A Gentle Reminder:

As with any natural remedy, always do a patch test on your inner arm first. For those with oily or combination skin, avoid heavy coconut oil application and harsh scrubbing, as they tend to aggravate shine and blemishes.
