A Vatican declaration, the "Infinite Dignity," has brought renewed attention to how religions define and interpret gender and gender roles.

Climate change is a global phenomenon, but its impacts are felt at a very local level. Take, for example, dust. Dust can have a huge impact on local air quality, food security, energy supply and public health. Yet, little is known about how global climate change is impacting dust levels.

In newly restored river channels on the Snoqualmie, baby Chinook salmon are confined in 19 enclosures about the size of large suitcases as they munch on little crustaceans and invertebrate insects floating or swimming by.

Violence and harassment on the job are all too common: More than 1 in 5 workers worldwide have experienced it, according to the International Labor Organization, with women slightly more likely to be affected than men. In the U.S., more than 2 million workers face violence on the job each year—and those are just the cases that get reported.

Dora Juhl, a 15-year-old teenager, walked into Dr. Rosa Goodrich Boido's obstetrical practice in Phoenix in January 1918. Juhl wanted to end her pregnancy.

A critical NASA mission in the search for life beyond Earth, Mars Sample Return, is in trouble. Its budget has ballooned from US$5 billion to over $11 billion, and the sample return date may slip from the end of this decade to 2040.

While some might think that family-run farms are a thing of the past, they are in fact the dominant business model in Europe. In 2020, they accounted for slightly more than 9 in every 10 of the EU's 9.1 million farms.

Angiogenesis is a process of forming hierarchical vascular networks in living tissues. Its complexity makes the controlled generation of blood vessels in laboratory conditions a highly challenging task.

Freeze casting is an elegant, cost-effective manufacturing technique to produce highly porous materials with custom-designed hierarchical architectures, well-defined pore orientation, and multifunctional surface structures. Freeze-cast materials are suitable for many applications, from biomedicine to environmental engineering and energy technologies.

Silicon Valley venture capitalist Marc Andreessen penned a 5,000-word manifesto in 2023 that gave a full-throated call for unrestricted technological progress to boost markets, broaden energy production, improve education and strengthen liberal democracy.

The Scottish government's decision to row back on its 2030 climate pledge illustrates the crux of any target: it's easy to set one with a big political flourish, but harder to follow through with a careful plan to achieve it.

Scientists from Nanyang Technological University, Singapore (NTU Singapore) and Temasek Polytechnic have successfully replaced half of the fishmeal protein in the diets of farmed Asian seabass with a "single cell protein" cultivated from microbes in soybean processing wastewater, paving the way for more sustainable fish farming practices. The findings are published in the journal Scientific Reports.

Given the spate of news about international trade lately, Americans might be surprised to learn that the U.S. isn't very dependent on it. Indeed, looking at trade as a percentage of gross domestic product—a metric economists sometimes call the "openness index"—the U.S. is one of the least trade-oriented nations in the world.

Researchers at Karolinska Institutet have developed a web-based platform that offers an unprecedented view of the human body at the cellular level. The aim is to create an invaluable resource for researchers worldwide to increase knowledge about human health and disease. The study is published in Genome Biology.

In addition to already known pollutants, the Bay of Santos—a city in the state of São Paulo (Brazil) that is home to the largest seaport in Latin America—has been affected by an emerging contaminant that is now present not only in the water but also in sediments and marine organisms throughout the São Paulo coastal region: cocaine.

A team of marine biologists, conservationists and environmentalists affiliated with multiple institutions in Australia has found that controlled culling of starfish can revitalize or promote regrowth of sections of the Great Barrier Reef.

A team of chemical engineers from Université PSL, CNRS, Harvard University and chemical company Calyxia, has discovered a way to prevent or delay coalescence in some immiscible liquids.

European astronomers have investigated a recently detected black hole designated Gaia BH3. In their results, they found that the black hole is associated with a nearby disrupted star cluster known as ED-2. The finding is reported in a paper published April 17 on the preprint server arXiv.

Photonic quantum computers are computational tools that leverage quantum physics and utilize particles of light (i.e., photons) as units of information processing. These computers could eventually outperform conventional quantum computers in terms of speed, while also transmitting information across longer distances.

Paleontologists have discovered giant tortoise fossils in Colombia dating back some 57 million years, the university leading the excavation said, with the findings key to understanding South America's prehistoric eras.

A Philippine court has blocked the commercial propagation of genetically modified golden rice because it said conflicting scientific views gave rise to "severe" health and environmental safety concerns.

A new study led by the University of East Anglia (UEA) shows how firms in the United States behave differently depending on the political party in charge—even if they do not change policies.

Nestlé has been criticized for adding sugar and honey to infant milk and cereal products sold in many poorer countries. The Swiss food giant controls 20% of the baby-food market, valued at nearly US$70 billion.

Diosgenin, a secondary metabolite isolated from the Dioscorea spp. plant family, is an irreplaceable and ideal starting material for the synthesis of steroid hormone drugs. Dioscorea zingiberensis is the world's most desirable and important plant source of steroid hormone drugs.

A research team has completed a high-quality chromosome-scale assembly of the Chuanhonghua 1 safflower genome. This work sheds light on the genetic underpinnings of crucial traits like linoleic acid (LA) and hydroxysafflor yellow A (HSYA) production. It sets a new precedent for crop improvement and functional genomics studies.
