Small-molecule switches put therapeutic CRISPR editing under on-demand control in living tissues
In a study published in Science Translational Medicine, a team of researchers led by Dr. Wang Yu from the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences developed PRINCE and Little Prince, dual small-molecule-controlled genome editing systems that
Gentle nudges for increased animal welfare
Gentle purchase incentives can lead customers to choose groceries with higher animal husbandry standards more often. A recent study at the University of Bonn at least suggests this. The researchers used two different animal welfare label posters as "nudges." Each poster changed
‘Hobbit’ hominins scavenged meat left over by Komodo dragons
An experiment that involved feeding a dead goat to a Komodo dragon as well as an analysis of thousands of ancient bones suggests that Homo floresiensis was neither a skilled hunter of big game nor a master of fire
Free-text answers and LLMs reveal hidden reasons behind human choices
Why do people make the choices they do? Researchers from the Center Synergy of Systems (SynoSys) at TUD Dresden University of Technology, the Max Planck Institute for Human Development, and the University of Basel present their new approach to finding answers to that question.

Scientists have grown wheat containing supersized starch granules—a leap forward in biological engineering with potential benefits for our daily diets and a raft of industrial applications.
Newfound family ties link Scythian elite burials across the Eurasian steppe
A new ancient DNA study published in Science Advances provides evidence that political power among Scythian elites may have been inherited through family lineages that extended across multiple burial sites. By combining archaeology, anthropology and genetics, the new study
Mammals use the same underlying system—preserved through evolution—to process smells
Picture a mouse taking rapid, staccato sniffs of a crumb it's found while foraging for food. Now compare that with a human leaning in for a single, deep inhale to gauge whether a cantaloupe is ripe. New research from Northwestern University has found that, like humans, mice
A benchmark for how different disturbances influence the loss and recovery of carbon and CO₂ in tropical forests
Tropical moist forests account for 70% of global living biomass. Deforestation and degradation—that is, the partial damage to tree stands—as well as the subsequent regeneration of forests therefore play a pivotal role in the global carbon cycle. While the effects of large-scale
Ancient ‘hobbits’ feasted on Komodo dragons’ leftovers
The hominins may have gone on adventures, but they lacked key skills of modern humans
Antarctic ozone loss drove unexpected Southern Ocean cooling, climate model shows
The Southern Ocean has long stood out as an oddity in the global climate system. While most of the planet's surface oceans have warmed in response to rising greenhouse gases, waters circling Antarctica showed an unexpected tendency to cool during the late 20th and early 21st
Colony connections determine ant wound care: Transitional workers treat injured nestmates
Patients in hospitals generally trust the nursing staff. After all, they have undergone training and, in some cases, have several years of professional experience. In the case of carpenter ants, it is not nursing expertise that determines who cares for the patients.
If we force online platforms to control harmful content, where does that leave sex ed?
Most of us have attended sex ed classes in school. If we're lucky, we'll learn about consent and how to roll a condom onto a banana. But the classroom rarely goes into the specifics of sexual health and well-being—including what to do when a condom breaks.
Ultrafast scanning tunneling microscopy reaches the quantum mechanical space-time limit for the first time
Werner Heisenberg's famous uncertainty principle describes one of the most intriguing features of quantum physics: certain pairs of physical quantities describing a particle, such as position and momentum, cannot simultaneously be determined with arbitrary precision—not because
Study reveals systemic barriers slowing down circular plastics transition
A new study from the University of Eastern Finland shows that the transition toward a circular plastics economy is hindered by systemic interdependencies and internal contradictions within ecosystems.
Paleontological study shows climate change makes marine animals shrink
Whether mussels, crustaceans or fish, marine animals have been responding to environmental crises with a reduction in body size for hundreds of millions of years. A new study by Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), in conjunction with the Universities of

Cosmic neutrino 'whispers' may surface in 5,000-day Super-Kamiokande signal
Neutrinos: They have no electric charge, pass through matter like a ghost and are so light they were initially thought to have zero mass. These are just some of the traits that make them so difficult to detect. Research on neutrinos requires massive underground observatories
Sea turtles diving through the eye of the storm help develop better cyclone forecasts
Every summer, communities across northern Australia brace for the tropical cyclone season. Tropical cyclones draw their power from the warm seas, extracting heat and moisture from ocean water.

The founding father of American literature, Charles Brockden Brown saw his nation's dark side
Murder, suicide, spontaneous combustion, sleepwalking, ventriloquism: These are some of the sensational events in the novels of Charles Brockden Brown (1771–1810). As the United States' first professional author, Brown is the Founding Father of the nation's literature. He is,
Songs play a greater role than plumage color in limiting bird hybridization, study suggests
When trying to attract and recognize potential mates, animals are known to rely on various signals, traits and behaviors. In the case of birds, these signals can typically include a wide range of sounds—such as trills, whistles, chirps or melodious notes defined as "songs"—as
Could this asteroid be a piece of the moon? A Chinese spacecraft is about to find out
The moon is not the only natural object traveling through space alongside Earth. Several small asteroids travel around the sun in near lockstep with our planet. And just like Earth, these space rocks also take a year to complete a full orbit. Today, we know of eight such
