Researchers in China have cross-calibrated radiation detectors on 25 navigation satellites. Data from two decades of measurements have been combined to create a record of the flux of relativistic electrons that impinges on Earth’s atmosphere. The technique can be applied to other satellite data, and could boost our understanding of the threat that this radiation poses to satellites and shed light on the solar processes that generate the electron flux.

The Global Positioning System (GPS) uses signals from a constellation of satellites to locate the position of receivers on the Earth’s surface to within several metres. There are currently 32 GPS satellites orbiting about 20,000 km above the Earth and each of them carries a radiation detector. These detectors allow scientists to observe changes in radiation levels in space. Much of this radiation comes in the form of high-energy electrons from the Sun, which can disrupt the operation of satellites and even damage them.

The electron flux rises and falls with the solar cycle. This has a period of about 11 years and involves the waxing and waning of sunspots, solar flares and coronal mass ejections.

For those who design and operate satellites, it is crucial to understand this electron flux. However, it has proven difficult to make full use of the data generated by these detectors because the instruments had not been cross calibrated. Indeed, measurement values of high-energy electrons can vary between satellites by several orders of magnitude when the flux is low. One important issue is that not all satellites use the same detectors – with two different instruments having been deployed.

Cross calibration

Now, researchers in China have done a cross-calibration of the particle detectors on 25 GPS satellites. The result is a calibrated dataset of relativistic-electron flux that spans two complete solar cycles (2000–2020).

To do this, the team looked at two different measurements made by the detectors. One is the differential electron flux at 2 MeV arriving from one specific direction. The other is the integral electron flux electrons arriving from all directions at energies greater than 2 MeV.

Because electron flux is affected by Earth’s magnetic field, the team had to consider its effect on measurements. This was done using a concept called magnetic local time, which accounts for the fact that Earth’s magnetic poles are offset from our planet’s axis of rotation.

The team used a satellite called NS59 as the reference for their study because its detector has produced a consistent set of data from 2004 – overlapping in time all other satellites in the study. By doing several statistical analyses, the team was able incorporate data from 24 of the 25 satellites. One detector, however, remained problematic and the researchers recommend that data from this satellite not be used.

The team says that their technique can now be used to cross-calibrate the detectors at other energies – there are 14 differential and 29 integral channels that can be also be analysed. They have already used the same techniques to cross-calibrate the GPS data with measurements made by satellites in  China’s BeiDou positioning system  and observations made by NASA’s two Van Allen Probes.

The research is described in Satellite Navigation.

Simulating quantum systems is something that classical computers struggle with. Not surprisingly, quantum computers are expected to do a much better job – particularly when a quantum-computer’s architecture is designed to solve a specific type of physics problem.

My guest in this episode of the Physics World Weekly podcast is Ross Jenkinson of the UK’s University of Manchester. He talks about the challenges and rewards of using quantum computers in particle physics – a field where classical supercomputers can struggle to simulate simple systems.

We also explore how quantum information theory is being combined with Einstein’s general theory of relativity to shed light on the nature of space and time.

This episode of the Physics World Weekly podcast explores how artificial intelligence can be used to improve the aerodynamics of passenger cars and other vehicles. My guest is David Wheater, who is vice president automotive at UK and US-based PhysicsX.

An aeronautical engineer by training, Wheater spent much of his career using aerodynamics to improve the performance of Formula 1 racing cars for several F1 constructors.

Now, his focus is on using AI-based “large physics models” to improve the performance of mass-produced vehicles. This involves combining computational fluid dynamics simulations with wind-tunnel experiments and real-world testing. In this wide-ranging conversation, Wheater explains the need for high-quality training data and we also explore career opportunities for physicists in this multidisciplinary industry.

The free-to-read Physics World Instrumentation and Vacuum and Briefing 2026 is now available. It includes R&D updates, interviews that explore technology commercialization, and a fun look at the quirky side of SI units.

One topic covered in the briefing is the world of quantum sensors. Over the years, physicists have developed some amazing quantum sensors, but many of the technologies have stayed in the lab because of the challenges of miniaturizing key components. With ultrahigh vacuum (UHV) playing an important role in quantum sensors based on cold atoms, Florence Concepcion of the UK-based firm Aquark talks about her mission to reduce the size and energy consumption of UHV systems.

Elsewhere in the issue, we look at how manipulating individual living cells plays an important role in biology and medicine. Trouble is, cells tend to stick together when grown in vitro and separating them often involves using harsh chemicals that can damage cells or modify their properties. In a special interview, Luke Cox, who co-founded the UK-based firm Impulsonics, discusses its system that uses ultrasound to gently separate living cells.

Another entrepreneur featured in this briefing is Brian Pogue, co-founder of DoseOptics. The US-based company has developed a system that detects the extremely faint Cherenkov light that is emitted when a radiotherapy beam strikes a patient’s skin. This allows the radiotherapy to be monitored in real time, ensuring that the beam passes through the target tissue and avoids healthy areas of the body.

Also included is a look at the use of intense laser light to accelerate particles. Find out how researchers in the US have created a compact, free electron laser that is driven by a laser plasma accelerator (LPA) – and it has also been used to create a beam of muons.

Finally, you can explore some of the curiosities of the International System of Units (SI), which is the bedrock of metrology. Although SI and its predecessors have been honed and re-defined over the centuries, it still has some surprising quirks. Ben Stein from the US National Institute of Standards and Technology explores some of these oddities including how the candela was derived from the brightness of a candle made from whale fat and beeswax – and the ongoing debate about using the dimensionless radian as the SI derived unit for planar angle.

Congratulations to Margaret Harris for winning the “Feature of the Year – specialist audience” award from the Association of British Science Writers (ABSW). The Physics World online editor was cited for her article “The physics Nobel prizes you’ve never heard of”. The ABSW describes the article as: “A refreshing angle to Nobel prize reporting. It was an eye-opener, told a great story and gave some deep historical context to the murky world of who wins the Nobels and why.”

In the run-up to each year’s Nobel prize announcements, Physics World editors explore aspects of the award that have often been neglected. As well as her award-winning article from 2025, Harris has argued the case that Lise Meitner should have won a Nobel for her work on nuclear fission (“Overlooked for the Nobel: Lise Meitner”). On a lighter note, Harris has described an e-mail exchange with physics laureate Brian Josephson about his tongue-in-cheek “paper” on mattress rotation (“How to rotate your mattress like a physics Nobel prizewinner”).

Data are at the core of science, but traditional journal articles normally deliver a distillation of the raw data gathered by the authors. While the movement towards open access to data is widely supported by researchers and funding agencies, a 2024 study by IOP Publishing revealed that many scientists still encounter a wide range of practical, ethical and technical barriers when it comes to sharing their data.

As a result, the publisher has launched a free online course that aims to give early-career researchers the practical skills and confidence they need to share and manage research data effectively.

To talk about the course and IOP Publishing’s open data policy I am joined by Laura Feetham-Walker, who is head of publishing strategy and performance at IOP Publishing.

IOP Publishing is a wholly owned subsidiary of the Institute of Physics and it publishes Physics World.

AI is upending the way voters take part in the democratic process. The worst part? You might not even know you’ve been affected.

In the county of St. Charles, Missouri, a race for county executive has devolved into slop-slinging of the AI variety. According to local channel First Alert 4, conservative candidate Jason Law is flooding the airwaves with an AI-generated video depicting his two rivals Steve Ehlmann and Bill Eigel as co-conspirators in a nefarious plot against voters.

“Steve, wake up, I’ve been telling people for 12 years that I’ll cut their personal property taxes, and they still believe me” the AI-Eigel declares in a generic AI-generated voice, rubbing his palms in glee.

“Property taxes have risen by 300 percent over the past 20 years and I just tell people there’s nothing I can do about it!” a grinning Steve Ehlmann replies.

Near the end of the ad, Law himself appears — also as an AI-approximation, with a stock text-to-speech voice — to declare that “we need a fresh start.”

Per First Alert, Law says the noxious campaign ad was inspired by a similar AI-generated smearjob by conservative reality TV star-turned Los Angeles mayoral candidate Spencer Pratt. Those ads take a similar tone, painting a sloppified Pratt as a superhero, and his opponent as a cartoon villain.

These are far from the only examples. Back in May, similar deepfake attack ads emerged in the race between incumbent Republican congressman Thomas Massie and the Trump-backed candidate Ed Gallrein. Unlike the local races in Missouri and California, both candidates were the targets of AI commercials, which were funded by independent PACs, rather than the candidates directly.

In Massie’s case, AI deepfake ads depicted the long-time representative in fake CCTV footage checking into a hotel with progressive Democrats Alexandria Ocasio-Cortez and Ilhan Omar, declaring “Thomas Massie caught in a throuple!”

During the race, Massie raged that “it’s always the losing campaign that does the crazy crap,” adding that it’s “frankly an insult to older voters who don’t know that AI exists,” Louisville Public Media reported.

Unfortunately for Massie, the ads — not to mention the Trump endorsement — appear to have worked out in Gallrein’s favor, as the challenger triumphed with 54 percent of the vote.

Here’s the thing about the water going into ChatGPT. It’s real water. It’s fresh. It’s drinkable. And most of the time, it’s not coming from anywhere near the person typing the question.

You are not paying for that water. Neither is OpenAI. Neither is Google, Microsoft, Meta, or Amazon, at least not in any way that resembles what the water is actually worth to the communities losing it. Someone else is paying, and if you have never heard their names, that’s because they aren’t the sort of people the AI industry finds it useful to talk about.

The families in Montevideo

In the first half of 2023, Uruguay was living through its worst drought in more than seventy years. Reservoirs supplying the capital ran dry. According to a Project Syndicate analysis by researchers Friederike Rohde and Paz Peña, republished by the Heinrich Böll Stiftung in November 2025, the Uruguayan government’s response was to relax its drinking water standards and pump brackish water from the Río de la Plata estuary into the public supply.

For weeks, working-class families in Montevideo were boiling salty tap water and trying to make it drinkable for their children.

During those same weeks, the government granted Google permits to draw from the remaining fresh water reserves for a proposed data centre.

That is not a hypothetical. It is not a projection. It is what happened, in one specific city, in one specific year, to one specific set of families whose taps ran salt while a foreign tech company was licensed to take the fresh water they could not have.

The residents in Fayette County

Nothing about this pattern is limited to countries you might be tempted to describe as vulnerable. According to a Fortune investigation published in May 2026 by news editor Catherina Gioino, residents of an affluent subdivision in Fayette County, Georgia, spent most of 2024 noticing that their water pressure was tanking. Something was drawing enormous quantities of water from the same system that fed their homes.

The county utility eventually traced the problem to a 615-acre data centre campus called Project Excalibur, owned by a company that is itself owned by Blackstone. One of its water hookups had been installed without the utility even knowing it existed. Another was flowing unmetered and uncharged. By the time officials caught up, the developer had consumed 29 million gallons of local water without authorisation. The retroactive charge was roughly 147,000 dollars. No fine was imposed.

In Tucson, Arizona, where the city council had already voted unanimously to reject a proposed data centre because the region gets seven to ten inches of rain a year, a construction contractor obtained a permit for water inside the city’s service area, transported it outside city limits, and used approximately 650,000 gallons of it on the rejected project without authorisation. The city shut off the meter. Construction continued.

The women in Cerrillos

The most sustained resistance to any of this has come from a group of women in the working-class Cerrillos district of Santiago, Chile, who in 2019 formed a neighbourhood organisation called MOSACAT after learning that Google was planning to build a data centre in their community. The proposed facility was projected to consume 7.6 million litres of fresh water a day. That is roughly what their entire neighbourhood uses in a year.

MOSACAT read the environmental report themselves. They organised. They took the case to a Chilean court. And in September 2024, that court forced Google to redesign the cooling system and undergo a fresh environmental review.

They are still fighting.

Why is this happening?

The pieces that connect these stories, the reason the same arrangement keeps repeating from Montevideo to Fayette County to Santiago, the specific mechanism by which drought-stressed regions become attractive rather than off-limits to the world’s largest technology companies, and the actual scale of what is being taken, are the substance of the video attached to this piece.

It walks through where the water goes, how much of it never comes back, and the far larger number that almost nobody in the industry reports.

By now, it should be pretty clear that the corporate executives of the world aren’t exactly into AI because they think it’ll cure cancer.

They’re making a different calculation, motivated by simple economics: pretty soon, they believe, AI will be efficient enough to do many or even all workers’ job, removing employee payroll from the corporate equation. That means more money for those at the top, and less time dealing with pesky annoyances like labor rights and health coverage.

For that to happen would take a series of technological miracles — as a recent study out of the University of California Berkeley shows, today’s cutting-edge AI tools are still incapable of completing the bulk of real-world tasks at a level comparable to humans.

Still, it’s clear executives are hungry for the kind of cost-savings AI could provide. Luckily, a new AI site offers a solution: OverpAId, a distinctly tongue-in-cheek project that facetiously claims to offer an AI-powered replacement for your company’s CEO — or as the site’s landing page puts it, the “world’s first Chief Executive Replacement Engine”.

“OverpAId is an Artificial Intelligence built from the ground up to do your CEO’s entire job — strategy, ‘vision,’ motivational all-hands emails — better, faster, and without ever once asking the board for a bigger jet,” the site exclaims.

The parodic offering claims to offer helpful features to help your team transition from an expensive human executive to a cheap AI equivalent. These include a “jargon bingo,” an AI-hype press release translator, a “talk to a real executive” chat widget (currently busted), and an ROI calculator that helps users distribute CEO pay packages equally across every remaining employee.

It hammers that point repeatedly, pointing out the fact that the average CEO-to-worker pay ratio is an astonishing 290 to 1 at large public companies (which is actually true, incredibly.)

While OverpAId is clearly a piece of satire, it gets at something very real: the fact that CEO pay has grown at an astonishing rate, while rank-and-file wages and salaries have crawled at a snails pace, in many cases not even keeping pace with inflation.

“Somewhere along the way, the story became: pay the person at the top enough, and the value will trickle down to everyone else,” the site explains. There’s just one problem with that telling: “It hasn’t. It doesn’t. It never really did.”

Comprar uma máquina de lavar nova está longe de ser uma tarefa simples, especialmente quando é preciso escolher entre uma lavadora com tampa frontal (front load) e outra com tampa superior (top load). Entre os diversos fatores que pesam nessa decisão, o consumo de água e energia costuma ser um dos mais importantes na hora de adquirir o eletrodoméstico ideal.

Isso porque a questão vai muito além da localização da tampa da máquina. O design e o funcionamento dos dois modelos interferem diretamente no consumo desses recursos essenciais e até mesmo no desgaste das roupas.

• 🫧 Confira ofertas de lava e seca no Canaltech Ofertas.

Para te ajudar na escolha da lavadora, o Canaltech analisou dados oficiais do Inmetro sobre os cinco eletrodomésticos mais vendidos de cada categoria para descobrir qual tecnologia entrega maior eficiência no consumo de energia e água.

O segredo está no movimento do cesto

A diferença real no gasto dos modelos de máquina de lavar começa pelo entendimento de como funciona a mecânica de lavagem de cada um. As máquinas de tampa superior realizam a limpeza das roupas por meio de processos de agitação ou turbilhonamento.

Isso significa que essas lavadoras precisam utilizar um volume maior de água para que as peças possam ser agitadas. O batedor localizado no centro ou a hélice no fundo movimenta continuamente as roupas, gerando o atrito necessário para remover a sujeira.

Acontece que esse método é um pouco mais agressivo aos tecidos, o que pode acelerar o desgaste de peças mais delicadas.

Já os modelos com tampa frontal utilizam o sistema de lavagem por tombamento. Nesse sistema, o batedor central é dispensado, e o tambor gira em torno de um eixo horizontal, aproveitando a força da gravidade para elevar as roupas e deixá-las cair durante a lavagem.

Esse processo é mais suave, pois gera menos atrito entre as peças, tornando-se menos agressivo aos tecidos. Além disso, como não há necessidade de encher o tambor com um grande volume de água, o consumo é naturalmente menor.

Qual modelo gasta mais energia?

As máquinas de lavar com tampa frontal tendem a ser maiores do que aquelas com tampa superior, o que pode levar alguns consumidores a acreditar que o consumo de energia desses equipamentos também é muito maior.

Essa percepção também acontece porque grande parte das lavadoras front load vendidas no Brasil são modelos lava e seca, e a função de secagem por calor realmente eleva o consumo de energia.

Mas o cenário muda quando colocamos no papel apenas o ciclo de lavagem convencional com água fria. Isso porque o sistema de lavagem por tombamento proporciona maior eficiência, além de muitos desses aparelhos contarem com tecnologia Inverter.

Esse recurso ajusta automaticamente a potência de funcionamento de acordo com a necessidade de cada ciclo de lavagem, contribuindo para reduzir o consumo de energia.

Para facilitar a visualização desse comparativo, reunimos dados de consumo elétrico (medidos em kWh por ciclo de lavagem) dos cinco modelos mais vendidos de cada categoria. Essas informações foram coletadas da Etiqueta Nacional de Conservação de Energia (ENCE) do Inmetro de cada eletrodoméstico.

Modelo	Categoria	Capacidade	Energia (kWh/ciclo)
Samsung WW11T4040BX/AZ	Tampa frontal	11 kg	0,26
Midea MF201W110WB/GK-01	Tampa frontal	11 kg	0,27
Brastemp BNF10ABBNA	Tampa frontal	10 kg	0,27
Midea MF200D130WB/GK-01	Tampa frontal	13 kg	0,28
Electrolux LFC12	Tampa frontal	12 kg	0,31
Electrolux LES11	Tampa superior	11 kg	0,34
Consul CWN14AB	Tampa superior	14 kg	0,36
Brastemp BWJ14ABBNA	Tampa superior	14 kg	0,40
Electrolux LED13	Tampa superior	13 kg	0,40
Electrolux LEC15	Tampa superior	15 kg	0,46

Como os dados oficiais demonstram, todas as lavadoras com tampa frontal mantêm médias de consumo inferiores em relação às de tampa superior. Elas operam sempre abaixo da marca de 0,31 kWh por ciclo e superam as máquinas tradicionais em eficiência energética.

Se compararmos os modelos de 13 kg da Midea e da Electrolux, a diferença é de 0,12 kWh por lavagem. Em uma residência que realiza três ciclos de lavagem por semana, isso pode representar uma economia aproximada de 1,6 kWh por mês que, apesar de modesta, se acumula ao longo do tempo e soma-se à economia de água proporcionada pelo sistema de lavagem por tombamento.

A principal diferença está no consumo de água

A eficiência energética já coloca os eletrodomésticos que utilizam a lavagem por tombamento um pouco à frente, mas é o consumo de água que amplia realmente essa vantagem. Isso porque esse sistema utiliza menos água durante a lavagem, resultando em uma economia significativa em relação aos modelos com tampa superior.

Separamos o volume total de água consumido por ciclo de lavagem nos mesmos dez modelos mais vendidos para deixar essa comparação ainda mais clara.

Modelo	Categoria	Capacidade	Água (litros/ciclo)
Samsung WW11T4040BX/AZ	Tampa frontal	11 kg	53
Midea MF201W110WB/GK-01	Tampa frontal	11 kg	81
Brastemp BNF10ABBNA	Tampa frontal	10 kg	85
Midea MF200D130WB/GK-01	Tampa frontal	13 kg	89,9
Electrolux LFC12	Tampa frontal	12 kg	92
Electrolux LES11	Tampa superior	11 kg	107
Consul CWN14AB	Tampa superior	14 kg	141
Electrolux LED13	Tampa superior	13 kg	150
Electrolux LEC15	Tampa superior	15 kg	160
Brastemp BWJ14ABBNA	Tampa superior	14 kg	184

O contraste fica evidente quando colocamos frente a frente modelos com capacidades semelhantes. Por exemplo, enquanto a máquina de tampa frontal da Midea de 13 kg consome cerca de 90 litros de água, a lavadora da Electrolux de 13 kg com tampa superior (LED13) alcança 150 litros por ciclo.

E essa diferença de 60 litros por lavagem tem um grande impacto a longo prazo. Em uma residência que realiza três ciclos de lavagem por semana, a economia pode chegar a cerca de 780 litros de água por mês, o equivalente a mais de 9,3 mil litros ao longo de um ano.

Tampa frontal ou superior: qual modelo vale o investimento?

Ainda que os dados apresentados apontem que as máquinas de lavar com tampa frontal oferecem maior economia no consumo de energia e água, a decisão sobre qual modelo escolher depende principalmente do planejamento financeiro e das necessidades da rotina de cada consumidor.

Se o orçamento para adquirir uma nova lavadora estiver mais apertado, os modelos com tampa superior cumprem bem o papel por apresentarem um valor de aquisição mais acessível.

Mas, se a prioridade for reduzir os gastos ao longo do tempo e houver uma margem maior no orçamento, vale a pena investir em uma máquina com tampa frontal. Ainda que exijam um investimento inicial maior, esses modelos podem compensar essa diferença com a economia de água e energia, além de reduzirem o desgaste das roupas.

Outra dúvida que costuma surgir entre os consumidores é sobre qual modelo gasta mais: uma lavadora tradicional ou uma lava e seca. O Canaltech também reuniu as informações necessárias para ajudar nessa decisão.
