Scientists have observed some incredibly energetic light coming from a nearby pulsar, the highest-ever from this type of star and close to the highest-ever seen from a cosmic source. Each photon had an energy of 20 TeV which is roughly 20 times the kinetic energy of a flying mosquito – and that comes from a […]

Nothing feels quite like the shared experience of hearing live music in a room full of other people. But new research is demonstrating how that experience may go far beyond how we feel, by showing how physiological processes can sync up across audience members at a classical music concert. The study, led by Wolfgang Tschacher […]

When you are firing a spacecraft at an asteroid, touching the spacecraft down on that asteroid very briefly to collect a sample, and then returning the sample to Earth, there are a lot of opportunities for problems. Despite the difficulty of the task, NASA successfully returned a sample of asteroid Bennu to Earth in late […]

Two years ago, when a team of archaeologists made the mind-blowing claim that they had identified 23,000 to 20,000-year-old human footprints in New Mexico, many were surprised but not everyone was convinced. However, new research has affirmed this dating, indicating that people were wandering around North America during the Ice Age. “The immediate reaction in […]

According to new research, there are probably more than 10,000 pre-Columbian archaeological sites hidden throughout the Amazon basin.  Indigenous societies have lived within the Amazon basin for more than 12,000 years. Throughout their history, these ancient peoples developed various techniques to cultivate and transform the land that surrounded them. They had a profound knowledge of […]

The Moon is appearing smaller and smaller in our skies. Over time, the number of total eclipses will decrease until one day, around 600 million years from now, humans (or whichever breed of dog takes over once we’re gone) will look up and see the final total eclipse as the Moon no longer covers the […]

Did you know that there’s a spice on Earth more valuable than truffles, wasabi, and even gold? You’ve likely seen it, tender red shreds of which you only need the tiniest amount to make a big impact on flavor. We’re talking, of course, about saffron. It comes from the purple flowers of saffron crocus (Crocus […]

Researchers are now capable of deflecting beams of laser light by using an invisible grating system made of air. The optical system is created using ultrasound and is not damaged by the laser (it is just air, after all), and it doesn’t reduce the quality of the beam. The team has already applied for a […]

Recordings of human voices scare the wildlife of the Greater Kruger National Park more than lions’ growls or even the sound of gunshots. Even in a national park, we’re probably the bigger threat. After all, lions only kill what they can eat – some humans will slaughter an entire rhinoceros so they can turn its […]

A team of astronomers believe they have detected objects moving far beyond the Kuiper belt, suggesting a possible second asteroid belt within our Solar System. The team has presented the findings at the 54th Lunar and Planetary Science Conference and is assembling a paper, but the work has not yet been peer-reviewed. NASA probe New […]

It might be dead and encased in a lump of amber (RIP), but there’s a new species of micro-wasp in town and it’s got some pretty odd antennae. The tiny wasp was discovered preserved in a piece of amber from Myanmar and is thought to be from the mid-Cretaceous period, around 100 million years ago.  […]

This year’s ozone hole over Antarctica has swelled to one of its biggest extents on record, encompassing an area roughly three times the size of Brazil. Scientists at the Copernicus Atmosphere Monitoring Service believe the exceptionally large patch of ozone depletion may have something to do with a colossal volcanic eruption that blasted a massive […]

If this looks a lot like your homework from back in the day, you can take heart in the fact that teachers have been scribbling all over their students’ work with a red pen for at least the last 4,000 years. This gessoed board, currently held at The Met in New York, shows an Ancient […]

If you were asked to guess when the steam engine was first invented, you’d probably guess around the 18th century, powering as it did the Industrial Revolution.  And you’d be right to – but well over a thousand years before that, shortly after 0 CE, Hero of Alexandria described a sort of steam engine, used […]

Lego has reportedly ditched its plans to make bricks from recycled soda bottles instead of oil-based plastic after finding that it would not actually reduce greenhouse gas emissions. However, the company maintains they’re still committed to bricks from sustainable materials within a decade. Lego’s chief executive, Niels Christiansen, told the Financial Times (FT) that the […]

The winners of the 2023 Nobel Prize in Chemistry are Moungi Bawendi, Louis E Brus, and Alexey Ekimov for their discovery and synthesis of quantum dots. The prize is worth 11 million Swedish kronor (around US$1 million at time of publishing), which will be shared equally among the three winners.  Quantum dots are nanoparticles; a […]

Fat Bear Week has returned for 2023 and the annual competition at Katmai National Park And Preserve in Alaska is delivering some absolute units. With famous faces like Chunk, Holly, and 747 back and in the running, who knows who will be the victor for this year? All that’s certain is you’ve got to be […]

Researchers have developed a new microfluidic device that could be used to simulate any human disease in multiple organs and test potential new treatments. How does it work? Named Lattice, the device consists of eight wells that can contain cell cultures from different organs, depending on the disease that a scientist might want to study. […]

The US Federal Communications Commission (FCC) has issued the first-ever fine for failing to properly dispose of space junk. In 2002, DISH Network launched its EchoStar-7 satellite. Ten years later, it filed a plan with the FCC for decommissioning the satellite at the end of its mission. This plan involved moving the satellite 300 kilometers […]

A Chinook helicopter got more than it bargained for when it swooped down low to take pictures of some captive crocodiles, as it accidentally triggered a giant orgy. Exactly what it is about low-flying helicopters that gets crocodiles in the mood isn’t known for certain, but it appears to mimic one of the natural cues […]
