We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.
Most water filter pitchers are made of BPA-free plastic. But as new research shows that bottled-water drinkers ingest tens of thousands of excess microplastic particles, wellness lovers have begun to look askance at water filters that are themselves made of plastic.
Openreach says the appeal of the project is its simplicity and scale: it uses fibre already in the ground, applies machine learning to "listen" for leaks in nearby pipes, and pinpoints issues to within a few metres. The pilot sees utility provider Affinity Water and UK technology company Lightsonic use Distributed Acoustic Sensing to convert Openreach's fibre optic cables into thousands of sensors that can "hear" and pinpoint leaks from surrounding water pipes.
While humans have assembled a lot of weather data, flash floods are too short-lived and localized to be measured comprehensively, the way the temperature or even river flows are monitored over time. That data gap means that deep learning models, which are increasingly capable of forecasting the weather, aren't able to predict flash floods.
Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.
Long-range radio waves can pass through obstacles more easily, which makes them perfect for monitoring expansive factories or outdoor infrastructure. A recent report by Fabrity highlighted that these systems use very little power. This allows sensors to operate for 5 to 10 years on a single battery. Using such tech means you do not have to install expensive wiring across your entire site.
Water meter transmitters are small devices that automatically send accurate water usage data to the city. But when their batteries die, the data flow stops. Once projected to have a 20-year lifespan, the city has said the batteries are dying faster than expected. The city has moved residents with failed units to "estimated billing," which means paying for estimated water use based on their past consumption.
To capture the biological impact of this extreme environment, I used a comprehensive suite of sensors and biomarker analyses. I wore a wireless electroencephalograph (EEG) system to monitor brain activity, sleep stages and neural signatures of stress and adaptation; the Oura Ring to continuously track sleep patterns, heart-rate variability and circadian-rhythm shifts; and the glucose monitor to follow metabolic responses in real time.
All of the appliances and systems are brand-new: the HVAC, the lighting, the entertainment. Touch screens of various shapes and sizes control this, that, and the other. Rows of programmable buttons sit where traditional light switches would normally be. The kitchen even has outlets designed to rise up from the countertop when you need them, and slide away when you don't.
They're special on a world stage, 85% of chalk streams are in England. They're wonderful habitats, they're great for people as well, people really enjoy them, whether it's areas like this where you can find kingfishers and grey wagtails and it's just a unique resource that we really should steward properly.
A Reg reader received an automated call warning of potential water discoloration during planned works from January 19-25. The message advised running taps for twenty minutes if the water appeared discolored - standard stuff, if a bit robotic. In the recording forwarded to us, a female voice told our reader what to expect. All good, if a little robotic. However, things went off the rails a bit when the robot attempted to read out the URL for Severn Trent: http://www.stwater.co.uk/discolouration.
The government said the plans would increase the number of England's official bathing sites to 464. An official bathing spot on the Thames in London would mark a "vast transformation" in water quality in the river which was declared biologically dead in the 1950s due to pollution, officials said. Water minister Emma Hardy said rivers and beaches were "at the heart of so many communities, where people come together, families make memories and swimmers of all ages feel the benefits of being outdoors safely".
As water-intensive data centres expand worldwide, their impact on sanitation, inequality and disease is emerging as a serious and under-examined threat. Bubble is probably the word most associated with AI right now, though we are slowly understanding that it is not just an economic time bomb; it also carries significant public health risks. Beyond the release of pollutants, the massive need for clean water by AI data centres can reduce sanitation and exacerbate gastrointestinal illness in nearby communities, placing additional strain on local health infrastructure.
In fact, Stawicki was on a mission to save the lives of around 1,000 zebrafish ( Danio rerio) in her laboratory. Similarities between lines of hair cells on the fish's flanks and those in the mammalian inner ear enable her to use them as a model to study hearing problems in humans caused by some antibiotics and chemotherapy drugs. A sensor had picked up that the lab's heating system had been knocked out by a power fault.
Signs of ageing accelerated when fish were exposed to the chemicals, according to the study, which could have implications for other organisms. Chemical safety regulations tend to focus on short-term exposure to high doses of pesticides and other chemicals, but the study focused on long-term exposure. Low doses of pesticides are widespread in the environment, so their effects should be studied and understood, the authors said.
The three-part docudrama Dirty Business, which started on Channel 4 on Monday and concluded midweek, has made the notion of going into the sea in the UK terrifying and unlike Jaws, this story is real. It is an example of what good drama can do that even the best reporting can't quite achieve.
In this photo, I'm preparing drifting buoys for deployment. This was my main responsibility aboard the RV Falkor (too), during a 27-day research expedition in October 2025 exploring the Malvinas Current, an ocean current that runs alongside Argentina. The expedition included biologists, geologists and physical oceanographers such as myself; I'm a PhD candidate at the Sea and Atmosphere Research Center (CIMA) in Buenos Aires, Argentina.
