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
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
The hominins may have gone on adventures, but they lacked key skills of modern humans
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
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.
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.
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
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.
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
New research has begun to lift the lid on the global online trade in land crabs, leading scientists to call for closer monitoring and regulation to better understand any effects it may be having on native populations and global biodiversity. The study, published in Oryx,
Chinese goldsmiths working during the Ming Dynasty were masters of their craft, capable of creating intricate and elaborate jewelry pieces. The evidence is there in the abundance of finds in royal and noble tombs across Hubei province.
Businesses today face growing dual pressures to deliver strong financial performance while also demonstrating environmental and social responsibility. New research from Murdoch University published in Business Strategy & Development has found that companies that aggressively
Earth was once covered by a global magma ocean, which later cooled and crystallised – now traces of this primordial event have been found in magma from a young volcano in the Indian Ocean
Planets beyond our solar system can have magnetic fields similar to those closer to home, astronomers said Tuesday after observing extreme winds on scorching worlds known as "hot Jupiters."
Short-lived sources of radio radiation in the sky, known as radio transients, can originate in the vicinity of supermassive black holes in the centers of galaxies. They are the result of processes that take place under extreme physical conditions. While most radio transients
A new study published in Movement Ecology describes how migratory fish passed through the Haringvliet Sluices before the introduction of Kierbeheer (the partial opening of the Haringvliet Sluices to allow limited saltwater intrusion and facilitate fish migration). The analysis,
