The sounds emitted by plants are ultrasonic, beyond the hearing range of the human ear. Plant sounds are informative: mostly emitted when the plant is under stress, they contain information about its condition.
Geologists have confirmed that our world will be getting a brand new ocean according to new research published in the peer-reviewed journal Geophysical Research Letters.
There are a number of places on earth that remain shrouded in mystery, despite the best efforts of scientists to explain them. Some of these places are locations where strange things have happened for centuries, while others are relatively new. But one thing is for sure – they all remain a mystery.
Back in 1,883, a pretty agate mineral was registered to the Natural History Museum’s Mineralogy Collection. Around 15 centimeters (6 inches) across, almost completely spherical but otherwise unassuming, the specimen has remained in the collection for the last 175 years, until a chance finding revealed it to be a dinosaur egg.
The specimen’s pretty colors of light pink and white interior caught the eye of Robin Hansen, one of the Mineral Curators at the museum who helped prepare the specimen when it was selected to go on display in 2018. Then a trip to a mineral show in France helped reveal the significance of the rock.
‘While I was looking around the show, a dealer showed me an agatised dinosaur egg, which was spherical, had a thin rind, and dark agate in the middle,” recounts Hansen in a statement. “That was the lightbulb moment when I thought: ‘Hang on a minute, that looks a lot like the one we’ve just put on display in the Museum!’”
Liquid trees using nanotechnology have all the benefits of trees and take up significantly less space.
My mum was due to celebrate a century of life and looking forward to getting her card from the Queen. She’d been living in an aged-care facility which had been through multiple lockdowns due to Covid. Our family started preparations for her birthday party; “hold the date” cards were sent.
On Mum’s behalf, we applied to receive the birthday card from the Queen. But early one night, after another lockdown, my dad rang. “I don’t think she’ll make it to the weekend,” he said. “Come quickly.”
As it happens, she hung on for another 18 days. The palliative nurse explained to my family that this was a time of being, rather than doing. We tried to make Mum feel loved, comfortable and with as little pain as possible as her body prepared to die.

Laser-driven Hohlraums filled with gas at lower densities (0.6 mg/cc) have higher efficiency compared to original ≥ 0.96 mg/cc fill because of reduced backscatter losses [Hall et al., Phys. Plasma…
