Unlocking the 'black box' of carbon materials: Study reveals origins of defect peaks

Carbon materials, such as carbon fibers and activated carbons, are essential across a wide variety of fields, encompassing everything from aerospace engineering to fuel cells and thermal insulation. For decades, Raman, infrared and X-ray photoelectron spectroscopy (XPS) have been

390 gravitational wave detections reveal hidden population of black holes

Astronomers have released the largest gravitational wave catalog ever, revealing 161 new black hole collisions and pushing the total number of detections to 390. Among the highlights are the clearest gravitational wave signal ever recorded, the most accurate location of a black h

‘Exploratory and curious animals’: mysterious rise in orca sightings off Northumberland co

Reasons for increase not clear but experts say it could be welcome sign marine ecosystem is becoming healthierThe Farne Islands off the Northumberland coast have long drawn fans of the natural world keen to catch sight of the resident guillemots and puffins.But as recently as las

Analog gravity advance offers new insights into Hawking radiation from black holes

Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter—as had previously been assumed—but also emit very faint radiation themselves. This radiation has not yet been

Quantum gravity tests may mistake ordinary spacetime for superposition

Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the behavior of the microscopic world, while Einstein's theory of gravity describes

Dynamic black holes may obey Hawking-style thermodynamics with an alternative entropy meas

Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, physicists have relied on complex equations from

Listen to Britain’s dawn chorus of 1976: the dramatic loss of birdsong in 50 years

Guardian recreates audio landscape of past filled by loud morning symphony before 73m wild birds were lostImagine a deafening abundance of birdsong so loud it wakes your children at dawn; the chirrup of house sparrows, the chattering of starlings, the melody of the wren, and the

A strange LIGO signal could reveal the missing link behind dark matter

An unusual gravitational wave signal has renewed hopes that primordial black holes, long considered purely theoretical, may finally be within reach of discovery. If confirmed, they could solve one of astronomy's greatest mysteries by explaining the nature of dark matter.

Long-lived radio outburst from black hole exhibits properties of the early universe

Short-lived sources of radio radiation in the sky, known as radio transients, can originate in the vicinity of supermassive black holes in the centers of galaxies. They are the result of processes that take place under extreme physical conditions. While most radio transients asso

‘They ate the shrimp, they even ate the crab’: Thai fishers count the cost of a voracious

Huge numbers of blackchin tilapia, a fish native to west Africa, are wreaking havoc among Thailand’s river ecosystems. Experts – and some chefs – are seeking sustainable solutionsThe menu at Kor-Tae seafood restaurant, in Thailand’s Samut Prakan province, is filled with Thai clas

A nearby black hole as a window into the early universe

An international team led by Stefanie Komossa from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn has studied a galaxy that has been shining exceptionally brightly in the radio regime for more than eight years. Although it is only 1.8 billion light-years away from u

Spring songbirds may help pollinate UK trees, with pollen on 89% of studied birds

The warblers—those harbingers of spring in the U.K.—have an unappreciated talent of a different sort. Common U.K. birds, including chiffchaffs and blackcaps, are playing a real role in the pollination of plants, according to new research in the Journal of Ecology.
