Egyptian cats meant for the gods led harsh lives, extensive museum collection reveals
More than 2,000 years ago, Egyptians offered cats to the gods. Now, a new study published in the Journal of Archaeological Science suggests that even cats destined for the gods did not necessarily live pampered lives.

What seal pups can reveal about the effects of mercury exposure
Marine mammals living along the Pacific Coast of North America encounter more than the fish, crustaceans, cephalopods and other marine mammals that live around them. Because contaminants such as mercury can move through marine food webs and biomagnify—becoming more concentrated
Researchers launch all-out assault on sawflies damaging wheat crops
Colorado wheat—the foundation for flour used in bread, noodles and pastries—has been besieged by the wheat stem sawfly, a native insect that recently developed a preference for wheat over native grasses. This destructive agricultural pest has spread across the state's Eastern

Making metal–organic frameworks easier to shape for electronic devices
In 1974, the University of Melbourne's chemistry professor Richard Robson had the idea of replacing the wooden balls and metal rods used in structural models with molecules and chemical bonds. He began experimenting with copper ions linked by a four-armed organic molecule,
Ice core records uncover widespread air pollution from early 20th-century copper production
About a century ago, the Anaconda Copper Mine complex near Butte, Montana, was emitting vast amounts of air pollution into the atmosphere. As small particles of arsenic and other heavy metals were carried by winds over the Arctic, storms eventually helped pull them to the
Toxic secrets are hiding in Arctic ice
Toxic metals can harm human health. Arctic ice cores trace arsenic, lead and other heavy metals to historic mining and smelting in Montana.
Digging up the past can change the ground beneath it
Archaeological excavation uncovers the past but also changes the landscape that has preserved sites for centuries or millennia. These changes influence water flow, soil erosion and the stability of exposed remains. Researchers from Istanbul Technical University and the U.S.
Heat-trapping carbon pollution drops, but scientists cite the Iran war rather than energy progress
Global carbon pollution dropped this year ever so slightly, but it's more because of oil shocks reverberating from the Iran war than anything the world has done to fight climate change, scientists said in a new study.
Math anxiety may be stopping students from learning useful AI and data skills
Artificial intelligence is increasingly becoming part of everyday life and work. AI can generate information, summarize evidence and perform calculations. However, it does not remove the need for critical thinking and conceptual understanding.
Light-pulse pairs reveal the femtosecond decay of an inner-shell hole in xenon atoms
Researchers at the UVSOR Synchrotron Facility (Institute for Molecular Science, Japan) and partner institutions have observed the decay of a xenon 4d core hole, an inner-shell vacancy, directly in the time domain. They used pairs of phase-coherent extreme ultraviolet pulses
AI-assisted atomic models reveal how protective shells regulate aluminum nanoparticle oxidation
Building an accurate model of how atoms interact is a complicated process. Researchers must choose new calculations, test successive models and track the mechanisms behind each interaction. But a newly developed AI agent called MLP Copilot has made this process much easier by

A KAIST-led research team has characterized how light propagates through and is absorbed by barium titanate (BTO), a promising material for next-generation optical communication devices. By clarifying optical properties that had been difficult to determine because of the
Electrical technique concentrates milk without using heat, challenging traditional preservation methods
Dehydrating milk to turn it into powder is, today, an energy-intensive process that subjects the product to high temperatures. Powdered milk is widely used by the food industry and allows the product to be stored and transported in a stable condition for long periods of time
Fossil CO₂ emissions projected to decrease in 2026 amid clean energy growth and Iran conflict
Global carbon emissions from fossil fuels are projected to decrease by 0.4% in 2026—driven by expansion of solar and wind power and the Iran conflict—according to new research by the Global Carbon Project. The 2026 edition (the 21st annual report) is published in the journal
Fossil fuel emissions are down in 2026. Green energy isn’t the reason
It's not quite a victory for humanity's transition to renewables. The dip is probably driven by high gas prices from the Iran war.
The surprising power of connecting with strangers
You're walking through the farmers market with a screaming toddler tucked under your arm football style. You're tired, you're leaving without the produce you came for and you're embarrassed.
After 40 years, CERN finds evidence of a one-in-10-billion particle decay
CERN scientists have finally found evidence of a particle decay so rare that it happens only once in roughly 10 billion decays, ending a search spanning more than 40 years. The breakthrough could help physicists uncover hidden particles and forces that lie beyond the reach of
Gatineau Park foliage reveals local Cold War nuclear testing legacy
For more than six decades, local scientists have collected sugar maple leaves from Gatineau Park to measure their radiocarbon levels, creating the longest continuous record of its kind. Now, a study of those leaves led by the André E. Lalonde National Facility for Accelerator
Accidental discovery enables room-temperature recrystallization of molybdenum
Researchers at the University of Rochester and Technion–Israel Institute of Technology accidentally discovered a new way to rearrange the internal structure of molybdenum—an extremely heat-resistant metal—at room temperature. Molybdenum is typically used to reinforce nuclear

Mount Sinai researchers have identified a single amino acid difference between rodent- and human-derived Andes virus isolates that changes how a key viral protein behaves inside human cells. The findings help explain biological differences between closely related virus isolates.
Starling numbers are declining—we're investigating whether their spectacular murmuration displays are changing too
Every autumn, from city centers to wetlands, starling murmurations attract crowds of spectators. Thousands of birds fill the sky, twisting and turning in extraordinary waves as the sun sets. An entire flock moves as one, creating shapes that shift and dissolve as quickly as
Methane-eating microbes grown on electrodes build electrically conductive nanowires

Water may play critical role in how our tissues stretch and spring back
Every time your heart beats, your lungs expand, or your skin stretches, a remarkable protein called elastin helps your body return to its original shape. But what exactly gives this protein its elasticity? For more than 50 years, scientists have debated whether elastin's
Archaeological finds at an Irish fort reveal insights into the finer side of medieval life
Popular media, from computer games to movies, often portray medieval life as being dominated by fighters and farmers. In these depictions, there's little evidence of a world beyond political struggle and simple subsistence.

Did early humans collect keepsakes 500,000 years ago?
Most of us are familiar with the urge to pick up a seashell from the beach or keep a stone from a hiking trip. The object itself may be ordinary, but to the person who keeps it, it serves as a reminder of a particular moment, place or person. Where did this behavior come from?

Some regions may already be living in a 1.5°C warmer world
Regions worldwide may have already experienced around 90%–94% of the warming expected when the global average reaches 1.5°C above preindustrial levels, and 65%–76% of that expected at 2°C of warming. The findings, published in Nature Climate Change, suggest that regional
Male lizard 'perfumes' may be more about rivalry than seduction
Animals communicate in ways that are sometimes obvious to us and sometimes almost completely hidden. Bright colors, songs and courtship displays are easy to notice. Chemical signals are different: an animal can leave a message behind long after it has moved away.
A stellar odd couple at an unusual stage of evolution
Most of the stars in the Milky Way are what we might call normal stars. They're main sequence stars like our sun, meaning they're doing what most people probably think stars do: shining as they fuse hydrogen atoms into helium atoms on a vast scale.
Upgraded microscope can now watch individual quantum particles in motion
