The Waste Age

Recognising that waste is central, not peripheral, to everything we design, make and do is key to transforming the future

The opposition between ‘nature’ and ‘culture’ is problematic for many reasons, but there’s one that we rarely discuss. The ‘nature vs culture’ dualism leaves out an entire domain that properly belongs to neither: the world of waste. The mountains of waste that we produce every year, the torrents of polluting effluent, the billions of tonnes of greenhouse gases, the new cosmos of microplastics expanding through our oceans – none of this has ever been entered into the ledger under ‘culture’. Of all the products of human hands, it’s the oeuvre that no one wants to own, discuss or preferably even see. Yet it can’t be assimilated into ‘nature’ either, at least not in the way that pre-industrial waste has been for millennia. This new, ‘improved’ waste is incompatible with Earth – too chemical, too durable, too noxious and, ultimately, too voluminous.

Waste is precisely what dissolves the distinction between nature and culture. Today, when the very weather is warped by the climate crisis, and plankton thousands of metres deep have intestinal tracts full of microplastics, the idea of a nature that is pristine or untouched is delusional. Nature and waste have fused at both planetary and microbiological scales. Similarly, waste is not merely a byproduct of culture: it is culture. We have produced a culture of waste. To focus our gaze on waste is not an act of morbid negativity; it is an act of cultural realism. If waste is the mesh that entangles nature and culture, it’s necessarily the defining material of our time. We live in the Waste Age.

If we look at the material ages of human history, from the Stone Age and the Bronze Age through to the Steam Age and the Information Age, we get the illusory sense that hard things are dematerialising. In fact, the opposite is true. The Steam Age launched a great explosion of material goods that has mushroomed exponentially ever since, while statistics about our current rates of waste numb the mind. What does it mean to say that, by 2050, as much as 12 billion tonnes of plastic will have accumulated in landfills or the natural environment? What does it mean to observe that more than a million plastic bags are consumed every minute globally, and that this amounts to between 500 billion and 5 trillion a year? Such numbers present a seemingly precise quantification yet one that’s utterly ungraspable. The average person just translates them into ‘a shitload’.

This is where the naming of ages becomes useful. The Anthropocene, or the age of human-driven planetary change, helps to evoke the new geological layer we are forming, a new planetary crust composed of our fossil-fuel residues, bottle tops and cigarette butts. Could we imagine any more literal entanglement of nature and waste? Some prefer a more political definition, the Capitalocene, which points the finger at a specific economic system: capitalism. But to say that we live in a Waste Age is to acknowledge both its geological and economic dimensions. It is to acknowledge that culture produces not just architecture and ingenious devices, but also a million plastic bags a minute. It is to acknowledge that growth is entirely dependent on the relentless and ruthlessly efficient generation of waste.

Is this an ungenerous and pessimistic take on human activity in the 21st century? On the contrary. Invoking the Waste Age offers the opportunity for a radical shift in late-capitalist civilisation. Only by recognising the scale of the crisis can we reorient society and the economy towards less polluting modes of producing, consuming and living. The problem is that waste has always been a marginal issue, both literally and figuratively. It has been dumped in and on the peripheries, consigned to that mythical place called ‘away’. It has always been an ‘externality’, an unavoidable byproduct of necessary industrialisation. But it is now an internality – internal to every ecosystem and every digestive system from marine micro-organisms to humans. If waste truly were to be a central issue – brought into the heart of every conversation about how things are extracted, designed and disposed of – it would transform society beyond recognition. To invoke the Waste Age is to usher in the hope of a cleaner future.

Waste as a phenomenon is actually a relatively recent concept. It was only with the advent of the Industrial Revolution, and its massive stimulation of production, that the material byproducts of extraction and manufacturing began to accumulate in mountainous heaps. The modern idea of waste, then, is only 250 years old.

Contrary to what we might assume, wastefulness is not a natural human instinct – we had to be taught how to do it. Disposability was one of the great social innovations of post-war society in the United States. When the first disposable products became available in the 1950s, from TV-dinner meal trays to cocktail cups, consumers had to be persuaded that this magical new substance – plastic – was not too good to be thrown away. They had to be instructed in the advantages of the throwaway society. Corporations – in particular, the petrochemicals industry – spent many years and millions of dollars lobbying for the replacement of paper grocery bags with plastic ones. With the advent of supermarkets, and a help-yourself service culture, every product now had to be individually packaged to survive on the shelves. And with the full bloom of convenience culture and take-away everything, disposability reached its apogee.

Some observers were quick to disapprove. Vance Packard’s book The Waste Makers (1960) offered a searing critique of the midcentury US at the height of its consumerist pomp. He details at length the different forms of planned obsolescence, from products engineered to fail to those that are simply meant to be more desirable than last year’s model. And, at almost every level of society, it is understood that such obsolescence is a necessary feature of a healthy economy – from politicians to cynical businessmen, to disillusioned (but compliant) designers, to consumers who think it is their patriotic duty to shop and support the economy. The very idea of the ‘lifetime guarantee’ conjured up the spectre of unemployment and shuttered factories. The Waste Makers is an X-ray of the American way of life – a society that replaced scarcity with overabundance, force-fed on easy credit and urban sprawl. Packard sees the problem as largely ethical – his concern is moral decay and the ‘sell, sell, sell’ commercialisation of everyday life. Yet at no point does he envision an ecological catastrophe. Soon after, Rachel Carson’s Silent Spring (1962), about the devastating effects of agricultural pesticides, would start to alert people to this problem.

Waste is deliberately generated as the very metabolism behind economic growth

By 1950, the world was producing about 2 million tonnes of plastic each year. In 2019, it was 368 million tonnes, with more plastic produced in the past decade than ever before. Nearly half of all plastic waste (47 per cent) comes from packaging, while 13 per cent comes from textiles. As David Farrier writes in his book Footprints: In Search of Future Fossils (2020): ‘it is likely that every single piece of plastic ever produced and not incinerated still exists somewhere in some form’. It’s believed there are more than 5 trillion pieces of plastic in the world’s oceans, many in the gyre known as the Great Pacific Garbage Patch. In his novel The Peripheral (2014), William Gibson accelerates this diffuse mess into an island with its own city, a plastic landmass inhabited by transhuman ‘patchers’. It’s a darkly humorous piece of dystopian fiction, and one that grasps the fact that the plastics industry is in no mood to shrink. In fact, fossil-fuel companies, bracing themselves for a drop in petrol use, are gearing up to massively increase plastics production. And who will stop them?

To say that we live in the Waste Age is not to focus attention on an unpleasant but marginal problem; it’s to say that the production of waste is central to our way of life. Waste is deliberately generated as the very metabolism behind economic growth. And while the waste crisis and the climate crisis are not the same thing, waste is a major driver of climate change. Plastic production is the second-largest source of industrial greenhouse gases, and methane generated in landfills is another significant contributor.

But to invoke the Waste Age is also to claim that waste is one of the great material resources of our time. It acknowledges the tremendous untapped value in what we throw away. Take the tens of millions of tonnes of electronic scrap that we discard every year. Instead of recycling it, countries such as the UK have been shipping it to Ghana – where it used to amass in Agbogbloshie, a large informal settlement in the capital Accra. Although it has since been dismantled by the authorities, for years Agbogbloshie was at the heart of a complex, internationally connected local economy, where e-waste was mined for precious metals and valuable parts. The methods can be noxious – plastic wires burned to release the copper – but the principle is sound. Some estimate that by 2080 the largest metal reserves will not be underground but in circulation as existing products. About 7 per cent of the world’s gold supplies, for instance, are trapped inside electronics. Suddenly ‘above-ground mining’ starts to make sense.

You might think that I’m suggesting that recycling is the answer to this crisis. Far from it. Recycling rates are pathetically inadequate, and in many countries the system is essentially broken. The notion of recycling works to justify the production of more virgin plastics and other materials, as if it’s alright because they will be recycled, when they won’t. Recycling will play an important role in the transition to the new economy – whatever that looks like – but it’s not enough on its own.

Meanwhile, any attempts to blame consumers for the waste crisis or the failures of recycling are, at best, wide of the mark and, at worst, deeply cynical. This was illustrated when it emerged that, contrary to government claims, more than half of the plastic purportedly recycled in Britain had instead been shipped abroad to be dumped or incinerated. In 2020 alone, more than 200,000 tonnes of our ‘recycled’ plastic was dumped and burned in Turkey. What a mockery of the consumer labour that went into sorting and rinsing yoghurt pots and milk bottles.

Similarly, post-consumer waste is only a small part of the problem. When it comes to e-waste, by far the greatest percentage has already been produced before a device is even purchased: the mining and manufacturing processes generate quantities of waste that no amount of recycling can come close to remediating. Since most of this waste happens ‘upstream’, before shoppers put their hands in their pockets, the onus is on governments to legislate, just as they have on other issues in the past – from banning of chlorofluorocarbons in fridges to mandating tempered glass in car windscreens. Manufacturers, too, must shoulder their responsibilities, but they can’t be relied upon to do the right thing.

What role can and should designers play in all this? Design has been a driving forces behind our prodigious waste streams in the past century. As the handmaidens of commerce, designers have been complicit in the throwaway economy: manufacturing planned obsolescence, promoting convenience culture, entombing products in layers of seductive packaging. In short, they’ve been doing what designers do best – creating desire. Paradoxically, even when designers achieve a sense of permanence, it is illusory; the iPhone seemingly achieved the Platonic ideal of the smartphone, only to be replaced year after year because of software innovations and the need to stimulate new sales.

However, the culture of design is changing, and the outlook of young designers today is very different from that of their predecessors. Many have very little interest in producing more stuff, and are much more invested in understanding the extractive processes behind products and their afterlives. Shorn of blissful ignorance and only too alert to the mounting crisis around us, designers are reinventing themselves as material researchers, waste-stream investigators and students of global economic flows.

The Dutch designer Christien Meindertsma was at the forefront of this shift more than a decade ago with her book PIG 05049 (2007), which mapped all of the parts of a single pig to their destinations in shampoo, chewing gum, bullets and a host of other unexpected products. She has since investigated what remains in the ash from waste incinerators, how to recycle woollen jumpers, and the potential uses of ripped-up linoleum. Formafantasma, two Italian designers of the same generation, have conducted in-depth research into the recycling of electronic waste and the history of the timber industry. The studio’s Simone Farresin and Andrea Trimarchi now teach a course called Geo-Design at the Design Academy Eindhoven in the Netherlands that calls attention to the geopolitical forces shaping the design industry. For designers of this stripe, the physical object is no longer an end in itself but a vehicle towards understanding the complex systems that produce it, and the even more opaque systems that dispose of it.

The most sustainable building is the one that already exists, yet developers are incentivised to build anew

Interrogating these systems is vital for reducing waste and pollution at each stage of an object’s life, from extraction to decomposition. If every product was evaluated in terms of how much waste it generated or how brief its lifespan was likely to be, it would transform the discipline, and consumer behaviour along with it. In many cases, those objects would not be brought into being in the first place. But how can designers implement strategic change when they must fulfil the briefs of their paymasters? The last thing any manufacturer or politician wants is reduced production. Well, in that case, designers need to convince them.

The designer’s powers of persuasion lie in making change manifest in tangible forms. Take the built environment, which accounts for 38 per cent of all carbon emissions when you factor in construction and energy use. We know that the most sustainable building is the one that already exists, and yet developers are still incentivised to demolish and build anew. The architects Lacaton and Vassal in Paris view demolition not just as waste but as a form of violence against the environment. In their transformation of social housing blocks that were once slated for demolition, they have demonstrated numerous times that such buildings can be adapted in ways that don’t just improve the architecture but also the residents’ quality of life. This is a powerful act of persuasion because it gives other municipalities the precedent they need when they are under pressure to demolish a run-down tower block.

These acts of persuasion are happening across every design discipline. Architects building taller structures with cross-laminated timber show that it’s possible to move away from carbon-heavy and hugely polluting construction mainstays such as steel and concrete. In consumer electronics, companies such as Fairphone and Framework design smartphones and laptops with modular parts, so that everything from batteries and cameras to motherboards can be replaced as they decline or evolve. While Apple and Microsoft have long used proprietary screws, glues and all manner of other strategies to prevent repair (though they’ve recently amended their policies somewhat), Fairphone and Framework are setting an ethical standard that one hopes consumers will find persuasive. In fashion, which is believed to be the second or third most polluting industry in the world, designers such as Stella McCartney, Bethany Williams and Phoebe English are demonstrating that it is possible to create desirable clothes out of recycled materials, dead stock and waste textiles. Granted, all of the above are still outliers – minnows in the mainstream – but their power lies in helping us see what a great abstraction such as ‘decarbonisation’ can look like at the everyday level.

As the public becomes more aware and more discerning, manufacturers will feel greater pressure to change – and more fundamentally than today’s epidemic of greenwashing suggests. But if the principles outlined above were widespread, it would challenge the industrial paradigm of the past 100 years. What does a society look like in which fridges last 50 years, not five? Where individual ownership of goods is replaced by communal sharing? Where distributed manufacturing is the norm, such that distant factories and global supply chains give way to more local, bioregional and artisanal production, close to the point of purchase? What are the implications of a world in which some products last forever and others, made of organic materials, decompose in days?

Our aesthetic sensibilities might have to adapt. After nearly a century of appreciating the hard-smooth-shiny perfection of plastics, we might need to embrace irregularity, imperfection, decay and decomposition. Many of these ideas and the products that could spring from them are nascent or niche. Critics will say ‘How do you scale that up?’ – to which we could retort that this impulse towards expansion is part of the problem. In the end, perhaps bigness is best replaced by myriad small-scale solutions.

There is hope, of sorts, in mushrooms. Mycelium has become the experimental material du jour, used in everything from bricks to handbags, but that is not the hope that I was referring to. Rather, it’s the fungus as a metaphor – an organism that can not only survive but even thrive in damaged landscapes, and help to restore them. The American anthropologist Anna Lowenhaupt Tsing has written compellingly about the ability of the matsutake mushroom to revive pine forests that have been ravaged by fire. ‘Matsutake’s willingness to emerge in blasted landscapes,’ she writes in The Mushroom at the End of the World (2015), ‘allows us to explore the ruin that has become our collective home.’

Mycorrhizal fungi create symbiotic networks with tree roots, nourishing them and enabling life after ecological catastrophe. This is a powerful demonstration of what Tsing calls ‘entangled ways of life’, and it is precisely that entanglement that designers are beginning to learn – the way in which every object is connected to the world, through myriad social and ecological processes, from raw material to waste material. And just as the 20th century was a summer of plenty, when we could consume and discard with abandon, so the 21st century will be defined by an autumnal scarcity, in which we have to be more resourceful and sparing – keeping our eyes trained on the forest floor.

Lychee Genome Tells a Colorful Story About an Ancient Tropical Fruit

Lychees

Fresh lychees.

Radiant and flavorful, lychees were so beloved that they were domesticated not just once in ancient times, but independently in two different regions of China, a study finds.

They’re prickly on the outside, sweet on the inside, and beloved for their iconic pink shells and pearly, fragrant fruit. In the U.S., you might encounter them as a flavorful ingredient in bubble tea, ice cream, or a cocktail. You can also peel them and eat them fresh.

Lychees have been grown in China since ancient times, with records of cultivation dating back about 2,000 years. Fresh lychees were an object of such desire that in the Tang Dynasty, one emperor set up a dedicated horse relay to deliver the fruits to the imperial court from harvests made far to the south.

Now, scientists have used genomics to peer even deeper into the lychee’s history. And in the process, they’ve uncovered insights that could help shape the species’ future, too.

“Lychee is an important tropical agricultural crop in the Sapindaceae (maple and horse chestnut) family, and it is one of the most economically significant fruit crops grown in eastern Asia, especially so to the yearly income of farmers in southern China,” says Jianguo Li, PhD, professor in the South China Agricultural University (SCAU) College of Horticulture and a senior author of the study. “By sequencing and analyzing wild and cultivated lychee varieties, we were able to trace the origin and domestication history of lychee. We demonstrated that extremely early- and late-maturing cultivars were derived from independent human domestication events in Yunnan and Hainan, respectively.”

Additionally, “We identified a specific genetic variant, a deleted stretch of genetic material, that can be developed as a simple biological marker for screening of lychee varieties with different flowering times, contributing importantly to future breeding programs,” adds Rui Xia, PhD, professor in the same college at SCAU and another senior author of the research.

“Like a puzzle, we’re piecing together the history of what humans did with lychee,” says Victor Albert, PhD, University at Buffalo evolutionary biologist, also a senior author of the study. “These are the main stories our research tells: The origins of lychee, the idea that there were two separate domestications, and the discovery of a genetic deletion that we think causes different varieties to fruit and flower at different times.”

The study will be published today (January 3, 2022) in Nature Genetics. It was led by SCAU in collaboration with a large international team from China, the U.S., Singapore, France, and Canada.

Senior authors are Rui Xia, Jianguo Li, and Houbin Chen from SCAU; Ray Ming from the University of Illinois at Urbana-Champaign; and Victor Albert from UB. First authors are Guibing Hu, Junting Feng, Chengming Liu, and Zhenxian Wu from SCAU; Xu Xiang from the Guangdong Academy of Agricultural Sciences; Jiabao Wang from the Chinese Academy of Tropical Agricultural Sciences; and Jarkko Salojärvi from the Nanyang Technological University.

A fruit so beloved, it was domesticated more than once

To conduct the study, scientists produced a high-quality “reference genome” for a popular lychee cultivar called ‘Feizixiao’, and compared its DNA to that of other wild and farmed varieties. (All the cultivars belong to the same species, Litchi chinensis).

The research shows that the lychee tree, Litchi chinensis, was likely domesticated more than once: Wild lychees originated in Yunnan in southwestern China, spread east and south to Hainan Island, and then were domesticated independently in each of these two locations, the analysis suggests.

In Yunnan, people began cultivating very early-flowering varieties, and in Hainan, late-blooming varieties that bear fruit later in the year. Eventually, interbreeding between cultivars from these two regions led to hybrids, including varieties, like ‘Feizixiao’, that remain extremely popular today.

The exact timing of these events is uncertain. For instance, the study suggests that one milestone, the evolutionary split between L. chinensis populations in Yunnan and Hainan, which took place before domestication, could have occurred around 18,000 years ago. But that is only an estimate; other solutions are possible. Still, the analysis provides a fascinating look at the evolutionary history of lychees and their link with humans.

When will this lychee tree flower? A simple genetic test could tell

The study not only adds new chapters to the history of the lychee; it also provides an in-depth look at flowering time, a hugely important trait in agriculture.

“Early-maturing lychees versus late-maturing lychees came from different places and were domesticated independently,” says Albert, PhD, Empire Innovation Professor of Biological Sciences in the UB College of Arts and Sciences. “This, by itself, is an interesting story, but we also wanted to know what causes these differences: Why do these varieties fruit and flower at different times?”

By comparing the DNA of many lychee varieties, the team identified a genetic variant that could be used to create a simple test for identifying early- and late-blooming lychee plants.

The variant is a deletion — a chunk of missing DNA — that lies near two genes associated with flowering, and may help to control the activity of one or both of them.

Yunnan cultivars that bloom very early have the deletion, inheriting it from both parents. Hainan varieties that mature late do not have it at all. And Feizixiao — a hybrid with nearly equal amounts of DNA from each of the two regional populations — is “heterozygous” for the deletion, meaning that it has only one copy inherited from one parent. This makes sense, as Feizixiao flowers early, but not extremely early.

“This is very useful for breeders. Because the lychee is perishable, flowering times have been important to extending the season for which the lychee is available in markets,” Albert says.

Sequencing the lychee genome is only the start

The team at SCAU initiated the lychee genome study as part of a bigger project that hopes to greatly expand what we know about the DNA of important flowering plants within the same family, Sapindaceae.

Sapindaceae is a large family that includes many economically important plants,” Xia says. “So far, only a few of them, including lychee, longan, rambutan, yellowhorn, and maple, have had their full genomes sequenced.”

“We, the College of Horticulture at SCAU, are working on a large collaborative project of sequencing more Sapindaceae species native to China and of economic importance, such as rambutan, sapindus (soapberries) and balloon vine, aiming at broad and thorough comparative genomics investigations for Sapindaceae genomics,” Xia adds. “The main research interests will be flowering, secondary metabolism leading to flavors and fragrances, flower and fruit development, among others.”

Sea Level Rise, Aquaculture are Making Bangladesh's Water Undrinkable

[By Riyan Sobhan Talha]

Twice a week, 50-year-old Brajasundari loads a collection of jerrycans onto a pedal cart, climbs aboard and travels three kilometres from her village Kanchrahati to buy water. Millions of women in arid and semi-arid regions of South Asia would call her lucky; they must do this twice a day, on foot. But Brajasundari lives in coastal Bangladesh, where there is water wherever you look – in ponds, streams, rivers and wells. However, it is all undrinkable.

Climate change has raised sea levels. The consequent ingress of saline water has poisoned freshwater sources throughout coastal South Asia. In Bangladesh, the salt water is seeping ever further inland.

So now Brajasundari travels to a shop where water is pumped up from a deep aquifer, treated and sold. This resident of Shyamnagar sub-district of Satkhira district, south-western Bangladesh, buys 60 litres of water on each trip, paying BDT 30 (USD 0.35) for the water and another BDT 20 (USD 0.24) for the pedal cart. The monthly expense of BDT 400 (USD 4.72) is over 10 percent of the average earnings of a landless agricultural laborer in this sub-district, going by the latest official statistics.

“I never thought that I might need to buy water for drinking,” Brajasundari told The Third Pole. “Earlier there were big ponds near our house. Everything is ruined by saline water. The problem of water is skyrocketing day by day.”

Back in 2011, a study led by Imperial College London and the London School of Hygiene and Tropical Medicine estimated salt intake from drinking water in Bangladesh’s coastal population exceeded recommended limits. Things have worsened since then.

Widespread problem

Satkhira is one of 19 coastal districts in Bangladesh and one of seven facing the Bay of Bengal. The coastal belt covers 32 percent of the country; over 35 million people live here, according to Bangladeshi government’s latest census.

Many studies have shown that people in coastal Bangladesh are suffering more and more as saltwater intrudes into their water supply due to climate change.

A 2014 World Bank report, River salinity and climate change: Evidence from coastal Bangladesh, forecast that by 2050 climate change will cause major changes in river salinity in the south-west coastal region during the October-May dry season. This will result in a shortage of drinking and irrigation water, with changes in aquatic ecosystems.

The water business

The shortage is here already. And all over coastal Bangladesh, it has spawned a new business: selling potable water.

A crowd in front of a water shop is a common sight nowadays. The shops are usually set up at points where relatively uncontaminated deep aquifers have been found. The water is pumped up, treated at a reverse osmosis (RO) plant at the back of the shop to get rid of the salt, and sold.

In the Nakipur neighborhood of Shyamnagar town, Shahinur Rahman owns such a shop, called the Mausumi Drinking Water Plant. He started the business in 2018 with an initial outlay of BDT 600,000 (USD 7,080). The RO plant can treat 1,000 litres of water per hour. He sells to 100-150 families every day, at 50 paisa (USD 0.0059) per litre.

“I earn BDT 40,000 (USD 472) per month,” Rahman told The Third Pole. “Selling water is big business here. People need it and we are just meeting the demand.”

Shyamnagar sub-district now has 25 RO plants for around 400,000 residents. All the plants are making money – hardly a surprise, since the residents have to pay more for water than residents in Dhaka, the capital of Bangladesh. The Dhaka Water Supply and Sewerage Authority charges BDT 12 for 1,000 litres of water, while people in Shyamnagar pay BDT 12 for 24 litres.

Residents of the capital must install their own water-purification systems at home. Despite that, the cost of potable water for them is many times less than for people in Shyamnagar, where the average income per head is less than half of that in Dhaka.

A 2013 study by the NGO WaterAid Bangladesh said that the cost of potable running water in the coastal areas is far higher than in Dhaka. The study was conducted in two coastal districts, Satkhira and Khulna.

Aftab Opel, who led the study and now works at another NGO, Vision Spring, told The Third Pole, “The private water business on the coast is booming now. It’s increasing day by day. The price of water has come down per litre compared to 2013; but it is still several hundred times higher than in the capital.”

Local factors worsen climate change effect

The saltwater invasion of drinking water sources has been worsened manifold by commercial shrimp farming, which started in coastal Bangladesh in the 1980s. Shrimp farmers flooded plots of land with saltwater because shrimps grow best in brackish water. That saltwater has seeped into aquifers everywhere.

Dilip Dutta, a professor in the environmental science department at Khulna University, said, “Large ponds became undrinkable due to saline water intrusion. Shrimp traders have not taken any initiative to create new water reservoirs. They only care about profit.”

A 2017 study by Sebak Kumar Saha of Australian National University, called Socio economic and environmental impacts of shrimp farming in the south-western coastal region of Bangladesh, said, “Higher salinity levels in water sources due to shrimp farming have severe negative impacts on people’s health and wellbeing. Salinization of freshwater supplies due to shrimp farming causes scarcity of drinking water, as well as water needed for other daily activities such as bathing and cooking.”

Health impacts

While residents of coastal areas like Shyamnagar are forced to buy water for drinking and cooking, they cannot afford to buy more. As a result, the increasingly saline water is used for washing and bathing, with serious health impacts. Skin infections are common, as are urinary tract infections and pelvic inflammatory disease among women. Poor menstrual health is another huge issue.

People do not even drink as much water as they should. A 23-year-old resident of Jelekhali village in Shyamnagar sub-district said, “As water is scarce, I have to calculate before drinking it.” She works at a shrimp farm, spending the whole day waist-deep in brackish water. There is no drinking water at her place of work. In 2019 she went to a local doctor with a urinary tract infection. The doctor told her she was not drinking enough water.

Ratna Rani Pal, a worker at Shyamnagar health center, said, “Most of the female patients come to us with various reproductive problems. The reason is lack of care and management of menstrual health.”

Shampa Goswami, director of Prerona Nari Unnayan Sangathan – a women’s rights organisation in Kaliganj sub-district of Satkhira – said, “The lives of women here are under threat. The intrusion of salt water, climate change and one storm after another are making women’s lives miserable.”

Up until she served in the Peace Corps in Malawi, Rachel Bielajew was open to a career reboot. Having studied nuclear engineering as an undergraduate at the University of Michigan at Ann Arbor, graduate school had been on her mind. But seeing the drastic impacts of climate change play out in real-time in Malawi — the lives of the country’s subsistence farmers swing wildly, depending on the rains — convinced Bielajew of the importance of nuclear engineering. Bielajew was struck that her high school students in the small town of Chisenga had a shaky understanding of math, but universally understood global warming. “The concept of the changing world due to human impact was evident, and they could see it,” Bielajew says.

Bielajew was looking to work on solutions that could positively impact global problems and feed her love of physics. Nuclear engineering, especially the study of fusion as a carbon-free energy source, checked off both boxes. Bielajew is now a fourth-year doctoral candidate in the Department of Nuclear Science and Engineering (NSE). She researches magnetic confinement fusion in the Plasma Science and Fusion Center (PSFC) with Professor Anne White.

Researching fusion’s big challenge

You need to confine plasma effectively in order to generate the extremely high temperatures (100 million degrees Celsius) fusion needs, without melting the walls of the tokamak, the device that hosts these reactions. Magnets can do the job, but “plasmas are weird, they behave strangely and are challenging to understand,” Bielajew says. Small instabilities in plasma can coalesce into fluctuating turbulence that can drive heat and particles out of the machine.

In high-confinement mode, the edges of the plasma have less tolerance for such unruly behavior. “The turbulence gets damped out and sheared apart at the edge,” Bielajew says. This might seem like a good thing, but high-confinement plasmas have their own challenges. They are so tightly bound that they create edge-localized modes (ELMs), bursts of damaging particles and energy, that can be extremely damaging to the machine.

The questions Bielajew is looking to answer: How do we get high confinement without ELMs? How do turbulence and transport play a role in plasmas? “We do not fully understand turbulence, even though we have studied it for a long time,” Bielajew says, “It is a big and important problem to solve for fusion to be a reality. I like that challenge,” Bielajew adds.

A love of science


Confronting such challenges head-on has been part of Bielajew’s toolkit since she was a child growing up in Ann Arbor, Michigan. Her father, Alex Bielajew, is a professor of nuclear engineering at the University of Michigan, and Bielajew’s mother also pursued graduate studies.

Bielajew’s parents encouraged her to follow her own path and she found it led to her father’s chosen profession: nuclear engineering. Once she decided to pursue research in fusion, MIT stood out as a school she could set her sights on. “I knew that MIT had an extensive program in fusion and a lot of faculty in the field,” Bielajew says. The mechanics of the application were challenging: Chisenga had limited internet access, so Bielajew had to ride on the back of a pickup truck to meet a friend in a city a few hours away and use his phone as a hotspot to send the documents.

A similar tenacity has surfaced in Bielajew’s approach to research during the Covid-19 pandemic. Working off a blueprint, Bielajew built the Correlation Cyclotron Emission Diagnostic, which measures turbulent electron temperature fluctuations. Through a collaboration, Bielajew conducts her plasma research at the ASDEX Upgrade tokamak in Germany. Traditionally, Bielajew would ship the diagnostic to Germany, follow and install it, and conduct the research in person. The pandemic threw a wrench in the plans, so Bielajew shipped the diagnostic and relied on team members to install it. She Zooms into the control room and trusts others to run the plasma experiments.

DEI advocate

Bielajew is very hands-on with another endeavor: improving diversity, equity, and inclusion (DEI) in her own backyard. Having grown up with parental encouragement and in an environment that never doubted her place as a woman in engineering, Bielajew realizes not everyone has the same opportunities. “I wish that the world was in a place where all I had to do was care about my research, but it’s not,” Bielajew says. While science can solve many problems, more fundamental ones about equity need humans to act in specific ways, she points out. “I want to see more women represented, more people of color. Everyone needs a voice in building a better world,” Bielajew says.

To get there, Bielajew co-launched NSE’s Graduate Application Assistance Program, which connects underrepresented student applicants with NSE mentors. She has been the DEI officer with NSE’s student group, ANS, and is very involved in the department’s DEI committee.

As for future research, Bielajew hopes to concentrate on the experiments that make her question existing paradigms about plasmas under high confinement. Bielajew has registered more head-scratching “hmm” moments than “a-ha” ones. Measurements from her experiments drive the need for more intensive study.

Bielajew’s dogs, Dobby and Winky, keep her company through it all. They came home with her from Malawi.

The Webb team has completed tensioning for the first three layers of the observatory's kite-shaped sunshield, 47 feet across and 70 feet long.

The first —pulled fully taut into its final configuration—was completed mid-afternoon.

The team began the second layer at 4:09 pm EST today, and the process took 74 minutes. The third layer began at 5:48 pm EST, and the process took 71 minutes. In all, the tensioning process from the first steps this morning until the third layer achieved tension took just over five and a half hours.

These three layers are the ones closest to the Sun. Tensioning of the final two layers is planned for tomorrow.

"The membrane tensioning phase of  deployment is especially challenging because there are  between the structures, the tensioning mechanisms, the cables and the membranes," said James Cooper, NASA's Webb sunshield manager, based at Goddard Space Flight Center. "This was the hardest part to test on the ground, so it feels awesome to have everything go so well today. The Northrop and NASA team is doing great work, and we look forward to tensioning the remaining layers."

Once fully deployed, the sunshield will protect the telescope from the Sun's radiation. It will reach a maximum of approximately 383K, approximately 230 degrees F, while keeping the instruments cold at a minimum of approximately 36K or around -394 degrees F.

The James Webb Space Telescope is the world's largest, most powerful, and most complex  science telescope ever built. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.Time saving tooling rods used on NASA's Webb Telescope sunshield

Fog Allows for ‘Impossible’ Photo of Milky Way Over Golden Gate Bridge

Photographer Michael Shainblum captured what was previously thought to be impossible due to heavy light pollution: a photo of both the Golden Gate Bridge and the Milky Way together

It takes great determination to head out in the night and patiently wait hours to photograph a landscape scene that may or may not work out in the end. Shainblum wanted to combine some iconic elements together into a photo, but getting everything to fall into place perfectly was a gamble and the idea of seeing stars and the bridge together was, to this point, a pipe dream.

But he got extremely lucky thanks to perfect conditions.

Fog over Golden Gate Bridge

The one photo wasn’t the only image he captured that night. Shainblum also took a “classic view” of the iconic bridge that many enjoy photographing. In the composition, he included both bridge towers, poking out of the soft fog that completely covered the scene, and the light trails of cars driving on the road.

To get different patterns of fog and variations of car light trails, Shainblum took multiple exposures and created a photo with colorful contrasts between the warm and cool tones.

Fog over Golden Gate Bridge

The Milky Way overlooking the hill deserved an image of its own, too. Unprepared to encounter a photo opportunity like this, Shainblum notes that photographers should take the chances when they present themselves, even if it means steering off the initial plan.

Fog over Golden Gate Bridge

Just before calling it a day, Shainblum took the few last long exposures of the bridge tower and the fog flowing past and through the gate for a simple, minimalist scene.

For photographers who are considering capturing the Milky Way, Shainblum recommends checking the weather first, such as on the National Oceanic and Atmospheric Administration website, noting the phase of the moon, which can be tracked using the PhotoPills app, and checking the light pollution.

When it comes to equipment, Shainblum recommends bringing a tripod and a wide lens, such as a 14mm-24mm full-frame lens, with an aperture f/2.8 or lower. In addition, a headlamp comes in handy, especially if the phone runs out of battery.

More of Shainblum’s educational and inspirational videos can be viewed on his YouTube and his photographic and video work can be found on his website and Instagram.

ESA Publishes Stunning Photo of a 2.5-Mile Wide Icy Martian Crater
JAN 03, 2022
DAVID CREWE


The European Space Agency (ESA) released a breathtaking new photo of a two-and-a-half-mile wide ice-covered crater on Mars affectionately nicknamed “Red Velvet.”


Spotted by Digitaltrends, the image was captured by the Trace Gas Orbiter that snaps images of the surface of the red planet, examines the gases in the atmosphere, and acts as a communications link between landers and other devices on the surface and planet Earth. The orbiter is officially a collaboration between the ESA and Russian space agency Roscosmos and the photo, originally captured on July 5, 2021, shows a nearly four-kilometer-wide perspective of the surface and the ice dusted crater near the north polar region of Vastitas Borealis on Mars.

“Like a sprinkle of powdered sugar on a rich red velvet cake, this scene from the ESA/Roscosmos ExoMars Trace Gas Orbiter captures the contrasting colors of bright white water-ice against the rusty red martian soil,” the ESA describes.

The ESA says the crater is partially filled with water ice more prevalent on the north-facing slopes since that region receives fewer hours of sunlight throughout the year with the dark sections on the crater edges likely containing volcanic materials like basalt, giving it a sort of scorched looking appearance.

The full resolution photo file of the crater, seen below, can be downloaded from the ESA website.

Raw output image

The presence of water on the planet is a big deal for space exploration, since bringing the precious liquid would be too heavy to carry all the way to the planet on a potential future manned mission. The presence of the ice means the liquid could be melted down and used for drinking water or fuel. The problem, according to the ESA, is that most of these deposits that have been found exist near the polar regions of the planet, and most missions want to land near the equatorial regions. Naturally, the next step is to seek out ice below the surface of the planet with missions like the upcoming Mars Ice Mapper, or the last option is to take the hydrated minerals from the soil and bake them to release any water they might contain.

Orion's fireplace: New image of the Flame Nebula

Orion's fireplace: ESO releases new image of the Flame Nebula
Do not let the image and the name of the depicted cosmic object fool you! What you see in
 this picture is not a wildfire, but the Flame Nebula and its surroundings captured in radio 
waves.The Flame Nebula is the large feature on the left half of the central, yellow rectangle
. The smaller feature on the right is the reflection nebula NGC 2023. To the top right of NGC
 2023, the iconic Horsehead Nebula seems to emerge heroically from the “flames." The 
three objects are part of the Orion cloud, a giant gas structure located between 1300 and 
1600 light-years away.The different colors indicate the velocity of the gas. The Flame 
Nebula and its surroundings are moving away from us, with the red clouds in the 
background receding faster than the yellow ones in the foreground. The image in the
 rectangle is based on observations conducted with the SuperCam instrument on the
 ESO-operated Atacama Pathfinder Experiment (APEX) on Chile's Chajnantor Plateau.

Orion offers you a spectacular firework display to celebrate the holiday season and the new year with this new image from the European Southern Observatory (ESO). But no need to worry, this iconic constellation is neither exploding nor burning. The "fire" you see in this holiday postcard is Orion's Flame Nebula and its surroundings captured in radio waves—an image that undoubtedly does justice to the nebula's name! It was taken with the ESO-operated Atacama Pathfinder Experiment (APEX), located on the cold Chajnantor Plateau in Chile's Atacama Desert.

The newly processed image of the Flame Nebula, in which smaller nebulae like the Horsehead Nebula also make an appearance, is based on observations conducted by former ESO astronomer Thomas Stanke and his team a few years ago. Excited to try out the then recently installed SuperCam instrument at APEX, they pointed it towards the constellation Orion. "As astronomers like to say, whenever there is a new telescope or instrument around, observe Orion: there will always be something new and interesting to discover!" says Stanke. A few years and many observations later, Stanke and his team have now had their results accepted for publication in the journal Astronomy & Astrophysics.

One of the most famous regions in the sky, Orion is home to the  closest to the Sun—vast cosmic objects made up mainly of hydrogen, where new stars and planets form. These clouds are located between 1300 and 1600 light-years away and feature the most active stellar nursery in the Solar System's neighborhood, as well as the Flame Nebula depicted in this image. This "emission" nebula harbors a cluster of young stars at its center that emit high-energy radiation, making the surrounding gasses shine.

With such an exciting target, the team were unlikely to be disappointed. In addition to the Flame Nebula and its surroundings, Stanke and his collaborators were able to admire a wide range of other spectacular objects. Some examples include the reflection nebulae Messier 78 and NGC 2071—clouds of interstellar gas and dust believed to reflect the light of nearby stars. The team even discovered one new nebula, a small object, remarkable in its almost perfectly circular appearance, which they named the Cow Nebula.

The observations were conducted as part of the APEX Large CO Heterodyne Orion Legacy Survey (ALCOHOLS), which looked at the radio waves emitted by carbon monoxide (CO) in the Orion clouds. Using this molecule to probe wide areas of the sky is the primary goal of SuperCam, as it allows astronomers to map large gas clouds that give birth to new stars. Unlike what the "fire" of this image might suggest, these clouds are actually cold, with temperatures typically just a few tens of degrees above absolute zero.

Given the many secrets it can tell, this region of the sky has been scanned many times in the past at different wavelengths, each wavelength range unveiling different, unique features of Orion's molecular clouds. One example are the infrared observations performed with ESO's Visible and Infrared Survey Telescope for Astronomy at the Paranal Observatory in Chile that make up the peaceful background of this image of the Flame Nebula and its surroundings. Unlike visible light, infrared waves pass through the thick clouds of interstellar dust, allowing astronomers to spot stars and other objects which would otherwise remain hidden.Hubble finds flame Nebula's searing stars may halt planet formation
