Why Ho Chi Minh City's pollution sources may have been misread for years

Biomass burning, including the combustion of wood, charcoal and agricultural residues, is a major source of PM2.5, a fine particulate matter that degrades air quality and poses risks to human health. Much of this pollution is tracked by looking at levels of levoglucosan, a chemic

Female baboons keep family bonds strong: Research reveals the benefits

Baboons are one of the most widespread of Africa's primate groups. They range across sub-Saharan Africa and into the Arabian Peninsula. Baboons' ability to spread across such a vast geographic area is based on their great ecological adaptability and dietary flexibility. This enab

The sun's outbursts may briefly weaken rain and snow events across North America

For decades, scientists have searched for a clear link between the sun's explosive storms and the weather that occurs on Earth. A breakthrough study from the University of New Hampshire reveals that in the hours and days following a solar storm, parts of North America can see sha

The solar gravitational lens could map white dwarfs and black holes

It feels like every few months we get to report on another academic paper singing the praises of the Solar Gravitational Lens (SGL). Partly, this is due to Dr. Slava Turyshev's astounding productivity in pumping out academic articles, but partly because such a groundbreaking miss

DNA databases unite to create a fully open resource for transposable element research

For more than three decades, researchers studying genomes have relied on foundational resources such as Repbase and, more recently, Dfam to identify and classify transposable elements—the mobile DNA sequences that shape genome structure, evolution and function. Now, Dfam and Repb

Age bias discovered in AI

Do responses generated by artificial intelligence systems such as ChatGPT reflect social prejudice? A KAIST research team has quantitatively analyzed and identified age-related stereotypes embedded in the responses of generative artificial intelligence. The study sheds light on t

Synthetic chemical framework can switch magnetic spin states at near ambient temperatures

There is growing demand for smart materials that can change their physical properties in response to various external stimuli such as light, heat, pressure, magnetic fields and electric fields. One such physical property is the magnetic state of material complexes, which depends

Women hold just 3% of jobs in tourism's biggest transport sector, global study finds

Women remain vastly underrepresented in tourism transport jobs worldwide, making up just 3% of land passenger transport workers (such as bus and train staff) in countries with available data, according to a University of Surrey-led report.

Sound waves reconstruct Alaska fireball path after cameras miss key details

When a bright fireball streaked across the Alaska sky last spring, the usual tools scientists rely on to track such events—cameras and satellites—did not provide a detailed picture. But the meteoroid left behind something else: low-frequency sound waves that traveled hundreds of

‘Happy vowel’ is a key indicator of social class in Manchester accents, study finds

Final vowel in words such as happy, baby and chilly varies clearly by social class across the city Pronunciation of the “happy vowel” is one of the key indicators of social class in Mancunian accents, researchers have found.A sociolinguistic study, by Lancaster University and the

Crystal-design principle reveals how competing molecular forces control structure, color a

Organic molecular crystals can respond to external stimuli such as heat, light, and mechanical force, making them attractive candidates for next-generation functional materials. However, predicting how multiple intermolecular interactions cooperate or compete to govern crystal be

How giant earthquakes can form at fault planes where theory says they should not

A research group led by Satoshi Ide from the University of Tokyo has demonstrated that classic earthquake generation theory does not hold in areas where the angle at which a tectonic plate dips under another is sufficiently low. The discovery explains why giant earthquakes can fo
