Asian cities are growing upwards more than outwards, satellite data show

September 2, 2024 admin

Cities around the world, but especially in Asia, are growing upwards faster than they are spreading outwards, a new study published in Nature Cities has found. In an increasingly urban and urbanising world, taller buildings can accommodate more people in less space but they can also negatively affect existing infrastructure, the local environment, and even…

Do some spiders exploit firefly’s flashing signals to lure more prey?

August 31, 2024 admin

Fireflies rely on flashing signals to communicate with other fireflies using light-emitting lanterns on their abdomens. In fireflies of the species Abscondita terminalis, males make multi-pulse flashes with two lanterns to attract females, while females make single-pulse flashes with their one lantern to attract males. Researchers now have evidence that an orb-weaving spider (Araneus ventricosus) manipulates…

The chemical treasury in garlic

August 31, 2024 admin

Plants, unlike animals, cannot escape predators. They are literally rooted to one spot. They have overcome this disadvantage by arming themselves with a vast chemical armory as a defense. Those parts of a plant that are below the ground are particularly vulnerable to attack. Bacteria, fungi, nematodes, larvae, snails, mice — the list of threats is long. Not…

Facts alone fall short in correcting science misinformation

August 31, 2024 admin

Just the facts may not be enough to overcome misinformation, a recent study indicates. In an experiment, 152 college students who had been exposed to misinformation read one of two articles intended to give them the correct, scientifically backed information. Those who read an expository article that had “just the facts” retained more misconceptions than…
