Scientists discover why gulls always prey on people's food
Scientists discover why gulls always prey on people's food
Anyone who has braved a stroll along England's coastline will be aware of seagulls' tyrannical regime. They prey on people eating chips, they swoop down on unsuspecting holidaymakers licking an ice cream, and they can be quite aggressive indeed. And now, terrifying research has revealed that they are more calculating than you may have previously thought. A University of Sussex study on herring gulls at Brighton beach found that the birds choose what to eat by watching what humans are enjoying. Scientists taped green (salt and vinegar) and blue (cheese and onion) packets of Walkers crisps to tiles and placed them a few metres from gulls on Brighton beach and filmed the birds’ behaviour from a distance. In some cases, the researchers ate from one of the bags of crisps. When the scientists didn't eat, less than a fifth of gulls approached the crisp packets placed nearby. But when the researchers were snacking on crisps, 48 per cent of the birds came to check out the packets. Nearly 40 per cent of such approaches ended with gulls pecking at the crisp packets, and of these, 95 per cent were directed at the same colour packet as the scientist was eating from. Sign up to our free Indy100 weekly newsletter “We’ve shown that adult gulls are able to pay attention to the behaviour of humans and apply that to their own foraging choices,” said Franziska Feist, a biologist and first author on the study. “Given that the urbanisation of gulls is very recent, this ability must come from the gulls’ general smartness and behavioural flexibility.” “It is likely that simply deterring the public from directly feeding gulls may not be enough,” Feist said. “They are still able to observe what we eat and that would inform their ability to target waste, litter and so on.” Dr Madeleine Goumas, an expert on herring gulls at Exeter University who was not involved in the study, said: “We already know from previous research that gulls use information from people when they’re searching for food. “This study shows that we aren’t only drawing gulls’ attention to where food is, but they also learn about the type of food we’re eating. Knowing this may have implications for how we reduce negative interactions between humans and gulls, as we seem to be inadvertently teaching gulls to exploit new food items.” Meanwhile, past alarming research revealed that gulls prefer food that has been touched by people.

Geminids meteor shower began life in a ‘violent catastrophe’, scientists say
Geminids meteor shower began life in a ‘violent catastrophe’, scientists say
The Geminids meteor shower began in a “violent catastrophe”, scientists have found. Every winter, the world is delighted by the meteor shower, which brings some of the most intense display of ‘shooting stars’. But that spectacle has been rivalled by its mystery. The Geminids are unusual in that most meteor showers are created when a comet leaves behind a tail of ice and dust – but the Geminids come from an asteroid, which do not usually leave behind a tail. Asteroids are chunks of rock and metal flying around in space. The Geminids appear to originate with one called 3200 Phaethon, which for an unexplained reason is affected by the Sun and leaves behind a stream across the night sky. “What’s really weird is that we know that 3200 Phaethon is an asteroid, but as it flies by the Sun, it seems to have some kind of temperature-driven activity,” said Jamey Szalay, research scholar at the Princeton University space physics laboratory and co-author on the paper. “Most asteroids don’t do that.” Attempts to solve that mystery have struggled in part because the meteor shower has only been observed from Earth. Now, however, researchers using Nasa’s Parker Solar Probe have been better able to examine the the Geminids. They suggest that a violent, catastrophic event gave rise to the meteor shower. That could have been a high-speed collision with another object in space, for instance, or a gaseous explosion. Some researchers have previously suggested that 3200 Phaethon might really be a comet, and that it lost its snow to leave behind just a rocky core that looks like an asteroid. But the new study makes clear that the origins of the meteor shower are much more dramatic than that. In an attempt to understand the meteor shower, researchers simulated three possible formation scenarios and then compared them with models based on observations from the Parker Solar Probe. That included a less violent scenario, a more violent one, and another that was in line with a comet. When they compared those scenarios with the actual observations, they found that the violent one was the most similar. That suggests that it was the result a collision or similar dramatic event. Researchers still do not know for sure what happened. But the new study helps narrow down the possibilities – as well as shedding more light on such events in space. The findings are published in a new article, ‘Formation, Structure, and Detectability of the Geminids Meteoroid Stream’, published in Planetary Science.

The Down Detector location map shows the outages are spread right across the UK with reports of the outages coming from the US and Australia as well. Instagram’s owners Meta have yet to publicly address the outage or say when the Instagram may come back online. According to Down Detector, 92% of the outages were on the app, 6% via the website and 2% on the login. Users cannot refresh their Instagram feed. Instagram had an outage on March 9 where thousands of users reported similar issues.
