The best fans to keep you cool in 2026 – tried and tested

27 May 2026 at 15:33

As temperatures soar across the UK, chill your space – and avoid energy-guzzling aircon – with our pick of the best fans, from tower to desk to bladeless

The best portable neck and handheld fans

Our world is getting hotter. Summer heatwaves are so frequent, they’re stretching the bounds of what we think of as summer. Hot-and-bothered home working and sweaty, sleepless nights are now alarmingly common.

Get a good fan and you can dodge the temptation of air conditioning. Aircon is incredibly effective, but it uses a lot of electricity … and burning fossil fuels is how we got into this mess in the first place. Save money and carbon by opting for a great fan instead.

Best quiet fan for the bedroom and best overall:
AirCraft Lume

Best fan for cooling:
Dreo TurboCool misting fan 765S

Mystery GPS jammer in Iran becomes test for NASA satellites’ capabilities

27 May 2026 at 21:43

NASA satellites designed to observe cyclone wind speeds and collapsing ice sheets have also proven capable of identifying the approximate locations of GPS jammers. That could help monitor high-risk areas for aircraft and ships navigating the growing prevalence of GPS interference worldwide.

Two different NASA satellite systems showed how they could locate a known but mysterious GPS jammer within several kilometers of its position in Iran, according to an experiment by Sean Gorman, CEO and cofounder of the location-based technology company Zephr.xyz that was detailed in the magazine GPS World. Such jammers use strong signals to overpower the weaker radio signals coming from US-operated GPS satellites and other global navigation satellite systems.

Such NASA satellites cannot perform “near-real time monitoring” or pinpoint the exact location of GPS jammers, said Clara Chew, principal scientist and lead of the GNSS systems and data team at the California-based satellite manufacturer Muon Space, who was not involved in the study. But Chew told Ars that identifying the approximate locations of GPS jammers “could potentially be helpful for flight planning” or for “indicating high risk areas for maritime shipping.”

The Guardian view on the Aberdeen South byelection: the politics of energy take centre stage | Editorial

31 May 2026 at 17:30

While Westminster’s attention is focused on Andy Burnham and Makerfield, another pivotal byelection is taking place in Scotland’s north-east

The coming byelection in Makerfield, from where Andy Burnham aspires to make rapid progress towards Downing Street, is perhaps the most consequential in British political history. But the decision by the Scottish National party’s former Westminster leader, Stephen Flynn, to relocate to Holyrood means that another pivotal contest is taking place more than 350 miles to the north. If Makerfield is a test case for Mr Burnham and Labour’s ability to see off Reform UK, Mr Flynn’s old constituency of Aberdeen South is on the frontline of the increasingly fraught politics of North Sea oil.

Labour, despite finishing second in the 2024 general election thanks largely to anti-Tory tactical voting, will not be expecting much this time round. The ramifications of Donald Trump’s reckless war in Iran have exposed Britain’s ongoing vulnerability to fossil-fuel-related energy shocks, highlighting the practical benefits of moving to a green economy. But the knock-on effects of the closure of the strait of Hormuz have also been a gift for the Scottish Conservatives and Reform, who are framing the byelection as a local referendum on reviving oil and gas production beyond Westminster-imposed limits.
