Having strong, biased opinions may say more about your own individual way of behaving in group situations than it does about your level of identification with the values or ideals of any particular group, new research suggests. This behavioural trait – which researchers call ‘groupiness’ – could mean that individuals will consistently demonstrate ‘groupy’ behaviour

In the north of the Arabian Peninsula, bordering the Nefud Desert, archaeologists have recently catalogued vast stone monuments dating back 7,000 years. Shaped like long rectangles, the ‘mustatil‘ structures are a mystery – but new evidence suggests they were possibly used for ritual or social purposes. Mustatils are amongst the earliest forms of large-scale stone

A car-size asteroid flew within about 1,830 miles (2,950 kilometers) of Earth on Sunday. That’s a remarkably close shave – the closest ever recorded, in fact, according to asteroid trackers and a catalogue compiled by Sormano Astronomical Observatory in Italy. Because of its size, the space rock most likely wouldn’t have posed any danger to people on

Just as you thought it was safe to go back to ignoring Betelgeuse, the red giant star started acting up again. After its first round of dimming, and then brightening, Betelgeuse has now started to dim once again. Moreover, this new dimming is inconsistent with Betelgeuse’s current brightness variation cycle – so, once again, the

An international team of marine scientists have discovered 30 new species of invertebrates in deep water surrounding the Galapagos, the Ecuadoran archipelago’s national park authorities announced Monday. The deep-sea experts discovered fragile coral and sponge communities including 10 bamboo corals, four octocorals, one brittle star and 11 sponges – as well as four new species

The existence of time crystals – a particularly fascinating state of matter – was only confirmed a few short years ago, but physicists have already made a pretty major breakthrough: they have induced and observed an interaction between two time crystals. In a helium-3 superfluid, two time crystals exchanged quasiparticles without disrupting their coherence; an

One of the major challenges in turning quantum technology from potential to reality is getting super-delicate quantum states to last longer than a few milliseconds – and scientists just raised the bar by a factor of about 10,000. They did it by tackling something called decoherence: that’s the disruption from surrounding noise caused by vibrations, fluctuations

We think of sharks as solitary creatures. Lurking silently beneath the waves, each single toothy predator operating alone, coming together only temporarily as feasting or mating dictates. We may, however, be totally wrong. According to new research, sharks could be forming large social groups from which smaller numbers break off to forage, and then return
