Fair matching systems can still produce unequal outcomes, new research finds
A computerized matching system can be designed to be fair and still produce unequal outcomes if the people using it do not understand how it works, according to...
Tropical rivers emerge as biggest oxygen-loss hotspots in a warming world
According to a study published in Science Advances on May 15, global rivers are undergoing widespread and sustained deoxygenation driven by climate warming, amo...
Sunlight-powered generation of correlated photon pairs
Pairs of correlated or entangled photons are a foundational resource in quantum optics. They are most commonly produced through spontaneous parametric down-conv...
Climate warming causes bleaching in key Arctic lichen, study finds
Long-term climate warming is causing a bleaching effect in a key Arctic lichen species, according to new research led by researchers in the School of GeoScience...
Implantable bacteria can now be safely contained, clearing a major hurdle for fighting infection and cancer
Researchers have long known that bacteria could potentially be used to deliver therapeutic drugs inside the human body. However, safely and successfully carryin...
Why is almost everyone right-handed? The answer may lie in how we learned to walk
It is one of the strangest puzzles in human evolution. About 90% of people across every human culture favor their right hand—with no other primate species showi...
Researchers identify enzyme that prevents chromosome breaks during DNA copying
Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged gene...
Warming climate favors shallower cyclones, challenging current risk assessments
As tropical cyclones (TCs) are among the most destructive natural hazards worldwide, understanding how TCs change under climate warming is of critical importanc...
Physicists create hybrid light-matter particles that interact strongly enough to compute
Eighty years ago, Penn researchers J. Presper Eckert and John Mauchly launched the age of electronic computing by harnessing electrons to solve complex numerica...
Dense soils may spread earthquake surface ruptures into wider damage zones, particle models suggest
Earthquakes can visibly and permanently crack the ground apart in dramatic and unpredictable surface fault rupture, but new research led by University of Michig...
Bacterial energy enzyme reveals dual-trigger sodium pump mechanism, offering antibiotic clues
The Na+-NQR enzyme is vital for energy production in pathogenic bacteria like the one that causes cholera, making it a highly promising target for new antibioti...
Q&A: Evolution may reshape how urban forests, wetlands and reefs protect cities
Over the past decade, cities around the world have increasingly turned to nature-based infrastructure to become more resilient in the face of a changing climate...
