The best science books of 2024
Books contemplating the human experience and some of humankind’s greatest challenges were among the Science News staff’s favorite reads this year.
Exposing the Waste-To-Energy Lie
Waste-to-energy incinerators are touted as ‘renewable’, attracting private investors and public subsidies. But is it all smoke and mirrors?
Book review: The Times Literary Supplement
Today’s water scarcity is only partly due to climate change, the journalist Tim Smedley explains in The Last Drop. The major culprits are humans, who, the
Book review: The Last Drop: Solving the World’s Water Crisis by Tim Smedley — how Britain’s taps could run dry
I read most of Tim Smedley’s book about the world’s impending water shortage while wallowing in the bath. It’s where I do much of my reading, happily turning the pages for hours until my flatmates begin to hammer on the door of our only bathroom. From that vantage, the thesis of The Last Drop: Solving the World’s Water Crisis felt utterly improbable. How can we be on the brink of a water shortage, not only elsewhere but in grey and soggy Britain too, when it flows so easily and cheaply...
The Guardian Long Read: ‘Drought is... the next pandemic’
During the summer months in the Oxfordshire town where I live, I go swimming in the nearby 50-metre lido. With my inelegantly slow breaststroke, from time to time I accidentally gulp some of the pool’s opulent, chlorine-clean 5.9m litres of water. I stand a bottle of water at the end of the lane, to drink from halfway through my swim. I normally have a shower afterwards, even if I’ve showered that morning. I live a wet, drenched, quenched existence. But, as I discovered, this won’t last. I am living on borrowed time and borrowed water.
Book review: The Last Drop by Tim Smedley
Tim Smedley’s The Last Drop is a smouldering indictment of the self-inflicted wounds we’re causing ourselves and Earth by careless exploitation of water.
The New Climate: a Publication Manifesto
Have you — like me — ever wondered why everyone isn’t talking about the climate crisis? It is clearly the most important, defining issue of our age. That’s why I’m attempting — proposing — a new publication that addresses the most important issue of our age, or arguably any age, head on: The New Climate.
Is air pollution causing us to lose our sense of smell?
For many people, a bout of Covid-19 gave a first taste (or rather a lack of it) of what it is like to lose their sense of smell. Known as "anosmia", loss of smell can have a substantial effect on our overall wellbeing and quality of life. But while a sudden respiratory infection might lead to a temporary loss of this important sense, your sense of smell may well have been gradually eroding away for years due to something else – air pollution.
The pollution causing harmful algal blooms
It is the "smell of decay and death", says Beth Stauffer, from the University of Louisiana. "It has a physical presence. This layer of very striking greens and blueish greens…when you put your paddle in it, you can feel it."
She's describing the harmful algal blooms (HABs) that used to be more associated with marine environments. But in recent years they've been moving further inland and affecting freshwater systems, too. And scientists such as Stauffer are trying to find out why.

How I earned my dad stripes and built a zebra crossing
Never have I been so pleased to see a boy racer. It’s July 2019 and I’m standing next to a busy B road in Banbury, Oxfordshire, with an unusual delegation of adults. I say “adults” because it’s school pick-up time, 3pm, and we aren’t with any children.
I have invited the local councillor to see how this main road near a school, with no pedestrian crossing, forces parents and children to run across and hope for the best, twice a day...

Why we're entering a vaccine RNAissance
Until recently most people had never even heard of mRNA vaccines. Now scientists believe they may be the key to solving a wealth of health problems.
Barely a year ago, Anna Blakney was working in a relatively inconspicuous, niche field of science in a lab in London. Few people outside of her scientific circles had heard of mRNA vaccines. Because none yet existed...

Is Reverse Osmosis water good (or bad) for your health?
Given that I’m writing a book about water, accepting an offer to review a home water filter made sense. But now it’s on my kitchen counter, I’m not sure if I want to use it. My reservation is this — how pure is too pure?
Britain needs to steer away from the killer car. We owe it to Ella
Ella Adoo-Kissi-Debrah died in south London from acute respiratory failure in 2013. She was nine. But it was not until last Wednesday, after a long legal battle, that a coroner finally ruled on the cause of her death. She has become the first person in the UK — and the world — to have “air pollution” listed on her death certificate...
Coming up for air
It’s no silver lining but the pandemic has at least led to an improvement in air quality. It’s up to us to keep the pressure on politicians to ensure the life-saving benefits are made permanent.
Picador pre-empts book on 'next big climate crisis'
Picador has pre-empted an investigation into water stress, billed as "the next big climate crisis", by environmental journalist Tim Smedley.

How to mine precious metals in your home
With so many of us now stuck in our homes during the pandemic, long-postponed jobs such as clearing out the loft or attic may seem like a good way of keeping the monotony at bay. Perhaps sorting through the “drawer of junk” in the kitchen or cleaning out that over-stuffed cupboard in the spare room are rising up your to-do list. If you need a little extra motivation for the spring clean, though, there’s probably treasure hidden in there.
The toxic killers in our air too small to see
After years of headlines about air pollution, we’ve been misled on a few things about the world’s biggest environmental health problem. For example, we’re told that “PM2.5” – solid pollution particles measuring 2.5 micrometres or less – can pass through our lungs and into our blood stream.
But, in fact, the vast majority of them can’t.
The biggest killer of all never makes the headlines, isn’t regulated, and is barely talked about beyond niche scientific circles: it’s nanoparticles.

Clearing the Air: Shortlisted for the 2019 Royal Society Science Book Prize
"Tim tells the full story of air pollution: what it is, which pollutants are harmful, where they come from and, most importantly, what we can do about them. Amidst terrifying statistics Tim uncovers the hope that remains for the planet. He tells inspiring stories..."
Clearing the Air - Bloomsbury
OUT NOW! Whilst living in London, sustainability journalist Tim Smedley became concerned by the escalating headlines about air pollution, and also by how little he knew about it. Outdoor air pollution was shortening his life – and potentially that of his young family. In a bid to learn more he travelled to several major world cities including Delhi, Beijing, Helsinki, London and Paris, and returned with the solutions...
Could wooden buildings be a solution to climate change?
I’m standing in a seemingly ordinary construction site of an unremarkable office block in east London. The seven-storey building is about two-thirds complete – the basic structure and staircases are in place, with plastering and wiring just beginning. But as I walk around, something different slowly reveals itself. The construction site is quiet and clean – it even smells good. And there’s an awful lot of wood...
Why are people thirsty for 'raw water'?
“Anybody here drink water, but wish you could pay more for it?” In January 2018, the “raw water” movement was doing the rounds on the US TV comedy circuit, and it was Stephen Colbert’s turn on The Late Show. “Well, good news,” continued Colbert, “because the next big start-up craze in Silicon Valley is ‘raw water’… water that’s unfiltered, untreated and unsterilised. Wow, drinking that sounds unsane!”

Deadly air in our cities: the invisible killer
"In the winter you can taste and smell the pollution,” says Kylie ap Garth, drinking coffee in a cafe in Hackney, east London. “My eldest is eight and he has asthma. Being outside, he would have a tight chest and cough. I just assumed it was the cold weather. I didn’t realise there was a link to the cars.”
She is not exaggerating. The main road from Bethnal Green tube station is clogged with traffic, the smell of diesel fumes mixing with smoke from barbecue grill restaurants and construction dust.
