With the ability to scan the entire southern night sky every three days, the huge Vera C. Rubin Observatory could be about to start solving the mysteries of the universe, from dark matter to Planet Nine
There appears to be a volcano near Jezero crater on Mars and the Perseverance rover might already have samples from it that we could use to precisely date the activity of another planet's volcano for the first time
Tech CEOs and politicians alike are preparing for the day that superintelligent AI takes over, whilst failing to deal with the issues in front of them – from copyright to autonomous killing machines
Attacks on Iran's nuclear facilities have already triggered at least one internal radiation leak, but should we be concerned that Israeli bombing could cause a larger nuclear accident?
The “One Big Beautiful Bill” just signed by President Trump will slash support for clean energy, leaving the US far short of its Paris Agreement pledge
Observations from NASA’s Juno spacecraft reveal that Jupiter’s strong magnetic field and the unique properties of its plasma can produce a truly novel kind of extraterrestrial wave near its poles
Proposed budget cuts in the US will lead to the loss of vital carbon dioxide measurements, but no other countries are preparing to step in so far, researchers warn
Instead of the big bang, some physicists have suggested that our universe may have come from a big bounce following another universe contracting – but quantum theory could rule this out
The Trump administration is attempting to argue that greenhouses gases don’t endanger people to reverse regulations limiting these harmful emissions – climate scientists are pushing back
The acting administrator of NASA, Sean Duffy, announced a directive to build a powerful nuclear reactor on the moon, but it is unclear what it would power – or even if his plan is legal
An analysis of active US mines finds they already collect virtually all of the minerals the country needs for batteries, solar panels and wind turbines – but these critical minerals mostly go to waste
The failure to agree a global treaty on plastic pollution highlights how the UN’s requirement for unanimity holds back environmental policy, but there are better ways to make progress
The UK government has announced a raft of tiny nuclear power projects, while Russia, China and a host of tech giants are also betting big on small nuclear reactor designs. Does the idea make sense and can they really be built any time soon?
Scientific evidence is lacking to support the US government’s decisions to caution against using a common painkiller in pregnancy and fast-track the approval of an experimental medication for autism
Solar electricity is growing rapidly, but can it really dominate the global energy system? Here is what it will take for us to power the planet on sunshine
The man who invented the web is aware of the many issues it faces, from problematic social media use to the rise of unfettered AI. He also has a plan to remedy the situation
President Donald Trump appears to have ordered a return to nuclear testing after decades of uneasy but effective treaties banning the practice – but will it actually happen?
Recent outages have revealed how vulnerable the internet is, but there seems to be no official plan in the event of a catastrophic failure. Meet the team of hackers who are ready to jump into action
Physics has a reputation for being dominated by men, especially a century ago, as quantum physics was just being invented – but there have been so many women who helped shaped the field since its inception
The 194 countries still taking part in UN climate negotiations reaffirmed the Paris Agreement following the US withdrawal, even if they agreed on little else
There are widespread concerns that deep-sea mining for metals will damage fragile ecosystems. But if mining ever goes ahead, hydrogen plasma could shrink the carbon footprint of smelting the metal ores
The Trump administration has targeted everything from public health to space missions for funding cuts, bringing an end to the longstanding US policy of scientific pursuits as a path towards progress and economic prosperity
Tantalising signs of past microbial life showed up on Mars this year, but to truly know whether they contain the answer to the biggest question in the universe, we will need to bring samples back to Earth
The US government is approving the drug leucovorin to address rising rates of autism, despite limited evidence that it works. This year, results from the largest trial yet should give more insight into its potential
Modelling suggests both carbon taxes and green subsidies will be necessary to decarbonise the US economy, but the inconsistent policies of successive presidents are the "worst case" scenario
An ambitious form of climate modelling aims to pin the blame for disasters – from floods to heatwaves – on specific companies. Is this the tool we need to effectively prosecute the world’s biggest carbon emitters?
The ice-covered island may be strategically important, but it's unclear that it could be a commercially viable source of minerals and oil in the near future
As tensions over Greenland rise, some Europeans are asking whether it is time to disentangle themselves from US tech dominance – but from smartphones to cloud services, rejecting US tech is easier said than done
With the Trump administration’s attacks on so-called woke AI it is becoming even harder to make the technology we use fairer and more diverse. Leading voices are speaking out, reports Catherine de Lange
The ongoing conflict around the Strait of Hormuz has become a situation in game theory known as a war of attrition. The maths behind it can help explain what's going on, says Petros Sekeris
