Scientists have identified eight common sound patterns that form the basis of birdsong after analysing more than 116,000 recordings from 3,160 songbird species worldwide. The study found that birds living in different habitats sing differently because forests, open landscapes and the way sound travels influence which songs work best, alongside evolution.
A new study has found that greater Japanese horseshoe bats adjust their echolocation calls to match the frequencies used by others in their colony instead of avoiding them. Researchers say this shared frequency creates a clearer listening range, helping bats detect prey more effectively despite many overlapping calls from nearby colony members.
Great discoveries often arise from unexpected observations and accidents. Alexander Fleming's penicillin discovery exemplifies this principle of embracing the unforeseen. Curious minds transform surprises into significant breakthroughs by asking questions. The journey of exploration can yield more value than the original destination. Innovation thrives when individuals remain open-minded to new possibilities and uncertainties.
For centuries, space has fascinated humans like no other. From the sun's glare to the moon's surface and even Saturn's shimmering rings, we have wanted to go up close and see it all. Now, two ambitious NASA-backed projects aim to truly touch Saturn's rings, venturing into what is known as one of the most dangerous environments in the solar system.
In a study published in Nature Communications, researchers from Sweden, US, Switzerland and Norway mapped what lies beneath all the glaciers on the planet and reached a shocking conclusion: when part of this ice disappears, Earth could gain 56,659 new lakes in areas currently completely frozen. This could increase the risk of flooding in Asia, Andes, Alaska and the Arctic
NASA developed non-rubber, airless metal tyres using Nitinol. These puncture-proof tyres adapts to harsh terrain and extreme temperatures without damage, offering a smooth ride. Future applications may include heavy-duty trucks and commercial aircraft landing gear.
