Although same-sex marriage has not been legalized nationally in Japan, various municipal governments have independently introduced partnership certification systems for same-sex couples. [...]
Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize themselves following incredibly precise patterns, while remaining flexible and robust. Scientists are increasingly probing the role the physical properties of embryonic tissues—such as rigidity or stiffness—play in this process. [...]
France experienced its hottest spring on record, the country's weather service said Tuesday, after an exceptional early heat wave that also broke seasonal highs in England and Wales. [...]
The Amazon rainforest responded to the most severe drought ever recorded in the basin with an unexpected defense mechanism. Researchers at the Max Planck Institute for Chemistry in Mainz, Germany, found that during and after the intense 2023–2024 El Niño cycle, the most intense drought ever recorded in the region, vegetation significantly changed its chemical emissions to cope with environmental stress. The study was published in Communications Earth & Environment. [...]
North Carolina's blueberry farmers may have a beetle problem. A new study from North Carolina State University has identified destructive beetles inhabiting North Carolina blueberry fields as Prionus imbricornus, a species of longhorn beetle. Known for their long antennae, the wood-boring beetles are an emerging pest in NC blueberries. Female adults typically lay their eggs in the soil near the roots of hardwood trees; their larvae, which can grow up to five inches long, then consume and destroy those roots, potentially killing the tree. Adults do not feed. [...]
Researchers have captured the first atomic structures of human SMUG1, an enzyme that helps cells repair damaged DNA. The findings provide new insight into how cells recognize and remove harmful DNA bases, and may support future efforts to develop drugs that target this DNA repair pathway. [...]
Four-and-a-half billion years ago, a massive world—possibly as big as the moon or even Mars—orbited our sun before crashing into another celestial body and shattering into rubble. Now, in a paper published in the journal Earth and Planetary Science Letters, scientists report the first definitive evidence that this lost planetary embryo (protoplanet) existed. Its unique geological makeup challenges long-held assumptions about how planets evolve. [...]
As U.S. cities prepare to host the FIFA World Cup, familiar warnings about human trafficking "spikes" at major sporting events have reemerged. [...]
If your community was threatened by a wildfire, would you be able to quickly evacuate? A new study from UC Santa Barbara reveals that the number of roads out of a community may be one of the strongest predictors of wildfire fatalities, and that a surprisingly specific threshold separates high-risk communities from safer ones. [...]
A new global study has found that people without access to clean drinking water are significantly more likely to experience food insecurity and food safety threats, underscoring the urgent need for coordinated global action to address these issues together. [...]
A fossil mammal tooth smaller than a grain of rice does not announce itself loudly. It must be hard won from sediment and stone. Then, under a microscope, it reveals itself—no longer just a speck of blackness but a surface of cusps, ridges, and worn edges. [...]
A key step in the origin of many pandemics occurs when an animal-borne virus infects humans and then evolves to spread more efficiently from person to person. That is why scientists and physicians keep a close watch on viruses that could jump from animals to humans, such as emerging strains of avian flu and bat coronaviruses, as well as viruses that have already crossed into humans but, for now, spread poorly among people, such as hantavirus and Ebola. [...]
Researchers at Rensselaer Polytechnic Institute (RPI) have discovered a microscopic organism that can transform into a cannibalistic "supergiant" that drastically changes size, shape, and behavior, and abandons filter-feeding to hunt and consume their genetically identical relatives. [...]
Globally, about 1 in 5 people in jobs live in poverty. A key reason lies in how global supply chains are organized. From agriculture to tourism, many jobs are embedded in systems that keep wages low, even as they generate value for international markets. [...]
China's Tianwen-2 sample-return mission is well on its way to its target, an asteroid called Kamo'oalewa. The spacecraft left Earth in May 2025 and should return in late 2027 with samples of a space rock that scientists had assumed originated from the moon. However, a new study published in Nature Communications suggests that we may be mistaken about the asteroid's origin. [...]
Canadian scientists have made a significant advance in understanding the mechanisms that enable embryos to properly form their limbs, thanks to new research led by Université de Montréal medical professor Marie Kmita at the Montreal Clinical Research Institute (IRCM). In findings published in the Proceedings of the National Academy of Sciences, Kmita and her team highlight the crucial role of certain molecular systems that act as true "genetic brakes," ensuring that development proceeds correctly. [...]
A research collaboration has developed a novel fluorescent nanosensor capable of rapidly detecting indole-3-propionic acid (IPA), an emerging biomarker linked to gut health and disease. The breakthrough is described in the team's paper, "Fluorescent Nanosensor for Indole-3-Propionic Acid Detection in Gut Health Monitoring," published in the journal Advanced Healthcare Materials.

The CEO of Blue Origin vowed its New Glenn rocket "will fly again before the end of this year" after a recent ground test ended in a massive fireball that damaged the launch platform. [...]
Industrial oxidation chemistry is a cornerstone of modern manufacturing, accounting for nearly one-third of all chemical industrial processes. While essential for making pharmaceuticals, dyes, and many specialty chemicals, industrial oxidation typically relies on high-temperature, high-pressure processes involving toxic oxidizing agents. This has motivated scientists to look into cytochrome P450 monooxygenases (P450s) as a compelling alternative. [...]
When you think of Antarctica, you might imagine a stark, otherworldly continent of endless, white ice, with the only sound being the wind punctuated by the crack of a glacier calving in the distance. [...]
The Euphrates River is the longest river in Western Asia and runs through the eastern side of the Fertile Crescent. Flowing over 1,700 miles from Turkey through Syria and Iraq, the river played a crucial role in sustaining the region known as the "Cradle of Civilization." Yet, researchers aren't sure about the river's origins or how tectonic activity might have shaped its evolution. A new study, published in Nature Geoscience, suggests that two ancient rivers, diverted by shifting plate tectonics, merged to form this vital river. [...]
Scientists have identified the two biggest reasons that once-pristine rivers across the Arctic are growing cloudy with toxic orange iron particles that smother insects and suffocate fish. [...]
Climate change is contributing to the escalation of existing local conflicts in Africa. A new WZB study by Ruud Koopmans, Daniel Meierrieks, and Daniel Tuki uses the example of pastoralist conflict between nomadic herders (mainly Muslim Fulani) and sedentary farmers in Nigeria to show how droughts triggered by climate change exacerbate existing religious conflicts. [...]
Magnets for electric cars and wind turbines contain only a small amount of the rare earth metal dysprosium. Yet, this metal is responsible for a large share of the environmental impact and costs, according to research by environmental scientists Stellina Samuel, Robert Istrate and René Kleijn. The study is published in the journal Sustainable Production and Consumption. [...]
Tracks left by some of the earliest complex animals are giving new insights into how they experienced the world. New research reveals how these creatures started to understand their surroundings, paving the way for animal life to spread across the planet. [...]
Sometime between 5.5 and 5.6 million years ago, two shell crushers squared off in the languid currents of an ancient Florida river. The fossils they left behind, discovered by paleontologists at the Florida Museum of Natural History, reveal the identity of the combatants and the outcome of their encounter. [...]
Two French astronauts are to blast into space next year, one of whom will stay on board the world's first commercial space station, under a new deal sealed between France and the U.S. company Vast. [...]
How did life make the leap from single cells to coordinated, multicellular organisms? And how do genetically identical cells still perform a version of that feat every time an embryo begins to take shape? [...]
