As populations decline and age across the developed world, compact city strategies, which oversee the consolidation of urban facilities and guide residents toward transit-served hubs, have become mainstream policies. Yet most evidence about their benefits comes from cities that
Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling. While ROS are established as essential signaling molecules in various organisms,

Traces or perforations caused by living organisms after an animal's death can be found on various dinosaur bone remains. These perforations, known as bioerosion structures, provide information that helps us understand relationships between living organisms in the past,
With the North American fire season underway, and a record number of acres already burned nationwide, NASA's Plankton, Aerosol, Cloud, and ocean Ecosystem (PACE) satellite's three instruments are observing vegetation precursors to fires, along with plumes of smoke and their
Archaeologists have uncovered an unknown stone circle that dates back at least 4,000 years to the Late Neolithic or Early Bronze Age and was most likely used for ritual activities.
Carbon quantum dots (CQDs) are tiny carbon-based nanomaterials that have attracted increasing attention as environmentally friendly alternatives to conventional heavy-metal quantum dots. They are lightweight, photostable and potentially biocompatible, and their light absorption
Flinders University researchers, in partnership with the River Murray and Mallee Aboriginal Corporation, have found evidence that points to 7,000 years of Aboriginal mining of stone at Sugarloaf Hill in South Australia's Riverland. The dating formed part of the first detailed
As drought and water uncertainty put increasing pressure on orchard systems, researchers at the USDA Agricultural Research Service's Appalachian Fruit Research Station in Kearneysville, West Virginia, launched a study in response to strong grower interest in how modern apple

Reliable operation of data centers has become essential to nearly all sectors of modern society, including health care, education, government services, power grid operation, banking, defense and disaster relief. New research published in Scientific Reports, led by University of
New research, published by the Rockwool Foundation Berlin (RFBerlin), shows that co-workers can have powerful—but opposing—effects on the careers of young workers. While some colleagues foster learning and long-term success, others may hinder career progression through direct
In May 2024, auroras were observed at unusually low latitudes across the globe, lighting up skies that rarely see such displays. Inside Earth's magnetosphere, the region of space surrounding our planet and dominated by its intrinsic magnetic field, something significant was

A new study reveals that goldfish can do far more than survive in the wild—they can fundamentally reshape freshwater ecosystems. Researchers found they cloud water, damage food webs, and hurt native fish populations, sometimes triggering major ecological shifts.
Imagine a global political summit that shapes the future of our planet, where one of the most populous countries in the world does not have a voice. This may seem unlikely, but currently 1.3 billion disabled people (nearly the population of China) do not have formal
Almost every material expands when heated. Well-known examples include railroad tracks and concrete roadways, which feature visible expansion gaps to accommodate this effect. However, thermal expansion poses a far more acute challenge for extremely precise technologies, such as
How do you teach someone to look at the moon? Not glance at it, the way we all have on a clear night, but truly read it, the way a geologist reads a hillside. That was the challenge NASA set itself before Artemis II, because when Reid Wiseman, Victor Glover, Christina Koch and
Over recent decades, harmful algal blooms have become increasingly common. These blooms often consist of bacteria called "cyanobacteria" in freshwater ecosystems. They can produce debilitating toxins, suffocate marine life by depleting oxygen in the water, and make water unsafe
Physicists at Paderborn University have, for the first time, experimentally demonstrated the so-called "return" of Rabi oscillations in semiconductor quantum dots. The phenomenon, which was first predicted theoretically in 2007, describes the decrease in the emission intensity
