Mass shootings in white-majority neighborhoods received roughly twice the news coverage of mass shootings in neighborhoods where a majority of residents were people of color, while coverage of police-involved shootings was disproportionately high in majority-minority
Reliable predictions of how the Earth's climate will respond as atmospheric carbon dioxide levels increase are based on climate models. These models, in turn, are based on data from past geological times in which the CO2 content in the Earth's atmosphere changed in a similar
Inflammation has to fight pathogens fast—but it can't get out of control. Researchers at the German Cancer Research Center (DKFZ) have now deciphered in more detail how the organism masters this balancing act. Their work shows that cells use two different strategies to
Chirality—often described as "handedness"—is a fundamental property of nature, underlying the behavior of molecules ranging from DNA to pharmaceuticals. While chemists have long known how to separate left- and right-handed forms of organic compounds, achieving the same control
New research has found that roughly half of Australia's freshwater fish are fond of snacking on animal and plant material, including fruits, from outside their aquatic habitats.
Is that bird feeder in your backyard really helping nature? How about feeding the chipmunks that come to your patio? Or handouts to wildlife in their natural environment, far from human habitation?
Longevity diets often focus on going plant-based, but a study in China has linked eating meat to a long lifespan, particularly among older people who are underweight
An international group of researchers led by Pompeu Fabra University has discovered the nanomachine that controls constitutive exocytosis: the uninterrupted delivery of spherical molecular packages to the cell surface. This is an essential activity present in virtually all
Valery Kyembo was leading an inspection of his community's protected forest reserve deep in the Democratic Republic of Congo's mining belt when two armed Congolese soldiers blocked their way.
The rockhead poacher is a little fish with a big pit in its head. The divot may be like a drum, making sound that rises above a chaotic, nearshore din.
Researchers at the Department of Energy's Oak Ridge National Laboratory are pioneering the design and synthesis of quantum materials, which are central to discovery science involving synergies with quantum computation. These innovative materials, including magnetic compounds
Sharks are the most feared predators in the sea, and their survival hinges on fearsome teeth that regrow throughout their lives. But changes in the ocean's chemistry could put those weapons at risk.
While a wealth of nutrient export models exists, a knowledge gap persists regarding how climate and land-use changes specifically drive dissolved inorganic nitrogen (DIN) export in subtropical catchments.
Dog attacks are on the rise in Australia. The most recent data from the Australian Institute of Health and Welfare show dog-related hospital admissions more than doubled in the eight years to 2021.
Victoria has just suffered some of its worst bushfires since the Black Summer fires of 2019–20. Over 400,000 hectares are estimated to have burnt so far, an area more than five times larger than Singapore.
