AMAZING OLYMPIC INNOVATIONS

The Summer Olympic Games comes around once every four years, and it's the ultimate stage for most athletes to display their sporting skills. While Olympians focus on their relentless training regimes ahead of their performances, the host country plans meticulously to present its city to the world. To show off their economic strength, innovation and dedication to environmental issues, Olympic hosts put on a display of the cutting-edge technology surrounding the competitions too.

The organisers of the 2024 Olympic Games in Paris have claimed that the upcoming event will be the most immersive series of the competition to date, including high-resolution 8K streaming and the use of artificial intelligence (AI) across the judging, security and entertainment sectors. One of the most significant targets set for these games is to halve the carbon footprint produced by previous Olympics. The Tokyo 2020, Rio 2016 and London 2012 games emitted an average of 3.5 million tonnes of carbon dioxide, so Paris 2024 will need to reduce this to 1.75 million tonnes to reach its target. To help achieve this, 95 per cent of the Olympic infrastructure already existed or will be used after the games. The stadium venues and any buildings that are specially made will continue to be used for other purposes after the closing ceremony.

Human refuse is ‘kick-starting’ the domestication of raccoons

City-dwelling raccoons are showing early signs of domestication. Using photos uploaded to the citizen science platform iNaturalist, researchers found that raccoons in urban environments had shorter snouts than their rural counterparts. The difference could be one of several traits that make up 'domestication syndrome', the scientists wrote in a study published in the journal Frontiers in Zoology. Domesticated animals typically become less aggressive towards humans over time. They gradually develop a relationship in which people provide for them in exchange for resources, such as meat and milk from livestock or labour from herding dogs. That process often involves selectively breeding animals for certain desirable traits, but it doesn't always begin that way. \"I wanted to know if living in a city environment would kick-start domestication processes in animals that are currently not domesticated,\" said Raffaela Lesch, a zoologist at the University of Arkansas at Little Rock.

ASTRONAUTS SEE COMET LEMMON 'ABSORBED' BY AURORAE

For skywatchers, scientists and even the astronauts on the International Space Station (ISS), the skies have been active. The Sun has released its largest eruptions of 2025, sparking a series of aurorae that have reached as far south as Mexico. While astronauts on the ISS had to take shelter during the recent solar storms to avoid potentially dangerous radiation, they did manage to capture this image of Comet Lemmon appearing near the aurorae on Earth.

A high-fibre diet may ‘rejuvenate' immune cells that fight cancer

Microbes in the gut can help the immune system fight cancer, and a fibre-rich diet may be the key to unlocking those benefits, a study in mice suggests. The immune system is a key player in the body’s battle against cancer. On the front line of this resistance are CD8+ killer T cells, a type of immune cell that marauds around tumours and then exterminates the cancerous cells. But after each successive battle, these cells become worn out and don’t find tumours as effectively. As such, treatments that provide the cells with enough pep to finish their job are in high demand.
