Little red dots may mark temporary black hole phase

Since their discovery by NASA's James Webb Space Telescope in 2022, little red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these extremely distant, compact red sources has ...

Rare-earth ions could enable telecom-ready control of interacting qubits

Quantum technologies are devices and systems that exploit the laws of quantum mechanics and could perform tasks that are difficult or impossible to tackle using their classical counterparts. These technologies process and ...

More green space alone won't beat urban heat

New research from Victoria University (VU) reveals that reducing the impact of extreme heat in urban areas requires more than simply adding green spaces—it requires a different approach to urban planning.

Extragalactic positron-annihilation hotspots might mean Milky Way produces far more positrons than thought

Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a distinctive 511 keV gamma-ray signal. ...

Evidence of giant rings in Venus's atmosphere uncovered in archived observations

In 2010, scientists waiting to use the William Herschel Telescope in the Canary Islands captured a brief 36 minutes of images of Venus. They were waiting for the sun to set so they could look at distant stars and dust disks ...

Kids who own cellphones have poorer reading comprehension scores than those who don't, researchers find

School cellphone bans might seem like a good way to improve learning for elementary school children, but new research published in Behavioral Sciences shows that simply owning a cellphone correlates with worse reading comprehension. ...

'Dead stars' may have surprisingly healthy appetites

"Dead stars" known as white dwarfs have already shown the potential to help us better understand how planetary systems, including our own solar system, take shape and evolve. Now, research from the University of Michigan ...

Birds flying in 'V' formation save energy with flatter flaps, new research shows

Scientists have known for years that birds like geese and ibises gain an aerodynamic advantage from flying in a "V" formation. Now, researchers from Brown University have provided new insights into the nature of that advantage.

Materials surrounding a fusion reaction can dramatically increase how often it occurs

Fusion at high temperatures powers the sun and, if harnessed, could provide a potential source of energy here on Earth. But controlling fusion reactions has other benefits. The process also generates subatomic particles called ...

Coastal and estuarine carbon removal technique may backfire when pushed too far

Scientists investigating a proposed way to remove carbon dioxide from the atmosphere using seawater have found that adding too much alkalinity to neutralize acids can trigger chemical reactions that undermine the process.
