Phys.org / Not every meal has the same impact: Researchers reveal the hidden footprint of our food
Leiden environmental researchers have mapped the environmental footprint of different diets and revealed which population groups have the greatest impact through their food choices. Their findings show where efforts to make ...
Phys.org / When mothers make the winners: How alpha female lineages dominate hyena clans
In mammals, males are usually stronger and more competitive than females. Males also show greater inequality in reproductive success—the number of offspring they produce—than females. In spotted hyenas, the opposite is true: ...
Phys.org / Exploring the lost golden age of language diversity before expanding empires drove a global decline
Today, people speak or sign around 7,500 languages. Yet this figure provides only a snapshot of a constantly changing history. How many languages existed before written records? Did agriculture reduce linguistic diversity ...
Phys.org / Moon baboon: New insight into the mind of ancient Egyptians
New research from the University of St Andrews has shed light on baboons, moonlight and their link to an ancient Egyptian deity.
Phys.org / Plant diversity boosts natural pest control in farms, while forests and grasslands follow different rules
Plant diversity has long been regarded as key to stable and resilient ecosystems. However, until now, little has been understood about why it has different effects in agricultural areas than in grasslands or forests. An international ...
Phys.org / Mars auroras reveal miniature version of Earth's magnetic engine
NASA MAVEN (Mars Atmosphere and Volatile Evolution) mission scientists have uncovered a key puzzle piece in understanding certain types of auroras on Mars, finding that they form in a similar way to Earth–based auroras.
Phys.org / Earlier toilet training could curb growing diaper waste crisis
Earlier toilet training and new recycling technologies are among expert-backed solutions to reduce the environmental impact of disposable diapers and other hygiene products, according to a new study led by UCL researchers.
Phys.org / Colorado basins supplying 70% of Lake Powell's water face major midcentury shortages
If the Colorado River Basin is the lifeblood of the American Southwest, keeping the region's agricultural, ecological and economic systems thriving, Colorado's West Slope River basins could be considered the heart. Together, ...
Phys.org / New multiplexing scheme accelerates long-distance quantum communication
Quantum networks, systems consisting of multiple connected nodes or devices that can transmit quantum information to one another, have the potential to advance future communications. These networks typically leverage entanglement, ...
Phys.org / Quantum Newton's cradle set to level up computing
Sending quantum information through a chain of qubits, like energy through a Newton's cradle, could be the key to faster operations and take quantum computing to the next level.
Phys.org / Lithium ions sprint up to 10,000 times faster when their molecular cages briefly open
An international collaborative research group led by Professor Bong June Sung of the Department of Chemistry at Sogang University and Professor Shinji Saito of the Institute for Molecular Science (IMS), National Institutes ...
Phys.org / Universal structure of exceptional points revealed in nonlinear light‑based systems
Exceptional points, or EPs for short, are among the phenomena of modern physics. These are special points or locations at which the properties of matter, space or time change. In a new theoretical study, researchers from ...
