For The Better

A research team elucidates how bacteria use the compound guanidine as a source of nitrogen.

The transition of human societies from hunter-gatherers to farmers and pastoralists is a more nuanced process than generally thought, according to a new study of peoples living in the highlands of southwest Ethiopia.

Researchers have identified a potential new therapy for COVID-19: a biologic substance created by reengineered human skin cells.

Dinosaurs went extinct 65 million years ago, mammoths 4,000 years ago, and the Christmas Island Rat 119 years ago. Since becoming a popular concept in the 1990s, de-extinction efforts have focused on grand animals with mythical stature, but now a team …

Tiny cellular machines called ribosomes build proteins. When this building process goes awry in bacteria, ribosomes collide, triggering the arrival of a first responder molecule that begins a rescue operation.

Earth’s thin crust softens considerably when it dives down into the Earth attached to a tectonic plate. That is demonstrated by X-ray studies carried out on a mineral which occurs in large quantities in basaltic crust. This softening can even cause the…

A new study investigates whether protecting and restoring large animal wildlife can help to support climate change goals.

Viruses are tiny but mighty intruders that can be found in the environment including in human bodies, and they can play a variety of roles in ecosystems. Viruses also come in a range of sizes. Some are even larger than bacteria, which scientists though…

In a new report, researchers say the challenges of treating long COVID are amplified by a critical issue: we do not know what constitutes long COVID or how to formally diagnose it, an issue that is further exacerbated by limited research data of varyin…

Toddlers whose mothers received special coaching in talking about memories grew into teenagers who experience better wellbeing, research shows.

A new study rolls back the curtain on half a century of evidence detailing the impact of climate change on more than 60 different bird species.  It found that half of all changes to key physical and behavioral bird characteristics since the 1960s can b…

Using super-resolution microscopy, scientists uncovered new details about the location of viral molecules in a cell after coronavirus infection.

A collaborative study confirms a potential new switching mechanism for a proposed generation of ultra-low energy topological electronics. Based on novel, quantum nanoribbons terminating on ‘zigzag’ edges, such devices would switch from non-conducting t…

People who suffer from persistent postural-perceptual dizziness (PPPD) experience unsteadiness, non-spinning vertigo and dizziness. These symptoms are exacerbated by movement, upright posture, and visual stimuli. In a new study, scientists have tried t…

Long-lasting immune activity in the airways might be the cause of persistent breathlessness following COVID-19, according to new research.
