Researchers have been able to use an analysis of ancient rock crystals – and the magnetism records locked inside them – to trace back the history of Earth’s inner core across hundreds of millions of years. Earth’s core, a dense hot blob of iron and nickel, is actually made up of two layers – the

At 5:29 am on the morning of 16 July 1945, in the state of New Mexico, a dreadful slice of history was made. The dawn calm was torn asunder as the United States Army detonated a plutonium implosion device known as the Gadget – the world’s very first test of a nuclear bomb, known as

Amber Heard has one of the world’s most beautiful faces – that is, according to cosmetic surgeon Julian De Silva. The claim has been recycled for some years now, and recently resurfaced in the wake of Heard’s (widely reported) trial with ex-husband Johnny Depp. But what is this claim based on? Well, according to De

Not all stars are happy to just hang around, orbiting the galactic center with all the other stars. Some stars go rogue, punted out across the Milky Way with significant force. These are the runaway stars, and we can trace their trajectories to understand violent events that can take place in the Universe. One such

The UK has provisionally recorded its highest ever temperature on Tuesday: 102.4 °F (40.2 °C). It was the first time the UK recorded a temperature over 102 °F (40 °C) per the Met Office, the official weather organization in Britain. The reading was taken around London’s Heathrow Airport just before 1pm local time. Temperatures were forecast

When the history of the rise of the robots is written, perhaps this might feature in the opening chapter: a seven-year-old boy has had his finger broken by a robotic opponent during a chess match in Moscow. There’s some debate about exactly what happened, but it seems that the youngster took a move faster than

Defense Innovation Unit’s Steve Butow: ‘We want to make GEO cool again’ WASHINGTON — The Defense Innovation Unit is funding space projects that the agency hopes will spur commercial investments in satellite refueling technologies and support services for geostationary satellites.  “Imagine a world where every 18 to 24 months, you could simply upgrade the processor

Colonies of ants can act a lot like neural networks, new research has revealed, with groups of the insects weighing up both external inputs and internal principles when making decisions about what to do as a collective. In this particular study, the team behind it looked at when and how ant colonies evacuated their nests

A team of physicists has used a pair of vibrating rods to measure the gravitational constant to incredibly fine precision. While the new technique has relatively high uncertainty, they hope that future improvements will provide a new pathway to nailing down this elusive constant. The gravitational constant, denoted as G, is the fundamental building block

Conspiracy theories are hardly a modern affliction: think of the JFK assassination or the long history of UFO sightings. Yet the internet is often said to have ushered in a ‘post-truth’ era, with social media, in particular, allowing for the spread of viral misinformation.  Whether or not that’s actually true is another matter, and it’s

Have you heard of LU Camelopardalis, QZ Serpentis, V1007 Herculis, and BK Lyncis? No, they’re not members of a boy band in ancient Rome. They’re Cataclysmic Variables, binary stars that are so close together one star draws material from its sibling. This causes the pair to vary wildly in brightness. Can planets exist in this

Plants can go to extraordinary lengths to tempt pollinators to do their bidding. From donning female insect disguises (complete with pheromones!) to lure lustful males, oozing the stench of rotting flesh to temp hungry flies, or, most commonly, offering bribes of sweet rewards for any who visits – no lengths are too gross or pricy

A digital twin is a copy of a person, product, or process that is created using data. This might sound like science fiction, but some have claimed that you will likely have a digital double within the next decade. As a copy of a person, a digital twin would – ideally – make the same

TAMPA, Fla. — The U.K. announced a public consultation July 22 to assess the environmental impact of the country’s first space launch, as part of the licensing process for clearing Virgin Orbit’s mission this year. The U.K.’s space regulator, the Civil Aviation Authority (CAA), is seeking comments on an environmental assessment from Virgin Orbit and

When you’re barely the size of an eyelash and on the hunt for fast-moving prey, having a bear trap strapped to your head might seem like a good idea. Of course, it’s all fun and games until it actually goes off. Even the slightest wobble in that trap’s arc could send your face on a

A new phase of matter has been observed in a quantum computer after physicists pulsed light on its qubits in a pattern inspired by the Fibonacci sequence. If you think that’s mind-boggling, this weird quirk of quantum mechanics behaves as though it has two time dimensions, instead of one; a trait that scientists say makes the qubits

A mysterious mummy of an ancient Egypt woman, who may have been pregnant when she died, likely also had cancer, according to researchers. Deformities in the mummy’s skull suggest a sizable tumor behind the left eye, but further tests are required to confirm that the tumor was cancerous.   The unusual mummy, who has been

The Sun’s glare is the main reason telescopes tend to look outwards from Earth, away from the center of our Solar System. New research reveals that for telescopic surveys prepared to peer in the other direction, there’s lots to be found. In particular, recent surveys are revealing near-Earth objects or NEOs, including asteroids we’ve never

Every five years, the Australian government releases a comprehensive report on the state of the nation’s environment, put together by a panel of independent scientists. The latest report, released this week, was long overdue and was always expected to be a doozy. In the past five years, severe coral bleaching events have whitened a third of

WASHINGTON — The Senate is moving forward with a revised version of a NASA authorization bill that formally authorizes the agency’s Artemis lunar exploration effort and extends operations of the International Space Station. The Senate Commerce Committee released July 20 the text of the Creating Helpful Incentives to Produce Semiconductors (CHIPS) Act, a bill primarily

As the first dinosaurs were finding their feet around 230 million years ago, the ancestors of modern mammals were also emerging. Somewhere along the way they developed a remarkable ability: to generate their own warmth.  This decisive evolutionary step towards endothermy – the ability to generate heat from within and keep a near-constant core body temperature even when

If chemists built cars, they’d fill a factory with car parts, set it on fire, and sift from the ashes pieces that now looked vaguely car-like.  When you’re dealing with car-parts the size of atoms, this is a perfectly reasonable process. Yet chemists yearn for ways to reduce the waste and make reactions far more

Researchers have peered back through 800 years of history to conclude that Mayapan – the capital of culture and politics for the Maya people of the Yucatán Peninsula in the 13th and 14th century CE – may well have been undone by drought. That drought would have led to civil conflict, which would, in turn,

It has been an exciting week with the release of breathtaking photos of our Universe by the James Webb Space Telescope (JWST). Images such as the one below give us a chance to see faint distant galaxies as they were more than 13 billion years ago. It’s the perfect time to step back and appreciate

Firefighters battled to contain wildfires sweeping across southwest Europe on Sunday as a heatwave showed no sign of abating, with Britain poised to set new temperature records this coming week. Blazes raging in France, Greece, Portugal and Spain have destroyed thousands of hectares of land and forced thousands of residents and holidaymakers to flee. It

On July 12, NASA, along with ESA and the Canadian Space Agency, will release the first observations from the James Webb Space Telescope in an event at the Goddard Space Flight Center. These will not, strictly speaking, be the first images from JWST: NASA has released engineering images for months to illustrate its progress commissioning

How life originated on Earth continues to fascinate scientists, but it’s not easy peering back billions of years into the past. Now, evidence is growing for a relatively new hypothesis of how life began: with a very precise mix of RNA and DNA. RNA and DNA both determine the genetic make-up of all biological life, with

Water gets boiled a lot – whether it’s a cup of tea brewing in a kitchen or a power plant generating electricity. Any improvements in the efficiency of this process will have a huge impact on the overall amount of energy used for it every day. One such improvement could come with a newly developed

For most of us, policing unwanted thoughts isn’t easy – but a new study outlines an approach that any of us could use in order to limit the number of thoughts that drop into our minds without an invitation. The study looks at the differences between reactive and proactive control. Reactive control is when we

Will we discover simple life somewhere? Maybe on Enceladus or Europa in our Solar System, or further away on an exoplanet? As we get more proficient at exploring our Solar System and studying exoplanets, the prospect of finding some simple life is moving out of the creative realm of science fiction and into concrete mission
