McGill researchers have developed a diagnostic system capable of identifying bacteria—and determining which antibiotics can stop them—in just 36 minutes, a major advance in the global effort to curb antimicrobial resistance ...

Australian researchers have developed a powerful new way to target deadly, drug-resistant bacteria by designing antibodies that recognize a sugar found only on bacterial cells—an advance that could underpin a new generation ...

A new study challenges the idea that climate change drove early human innovation. Instead, researchers find that cultural developments arose under different environmental conditions, shaped by movement, interaction, and knowledge ...

Scientists have captured a rare view of one of the ocean's least understood whales—without ever seeing it. By listening to the sounds beaked whales naturally produce, researchers have reconstructed a three-dimensional picture ...

Should we protect an emblematic species if it may come at the cost of another one—particularly in ecosystems that are still recovering from human impacts? This is the conservation dilemma facing Monte Leon National Park, ...

For over a century and a half, life expectancy has steadily increased in the wealthiest countries. Spectacular climbs in longevity have been noted in the 20th century, correlating with the slump in infectious illnesses and ...

Oysters famously filter their surrounding water, but it turns out they are removing more than algae and excess nutrients. New research from William & Mary's Batten School of Coastal & Marine Sciences & VIMS shows they can ...

Scientists at Rutgers University–Newark have developed a first-of-its-kind RNA-based nanotechnology that assembles itself inside living human cells and can be programmed to stop propagation of harmful cells. The findings, ...

Ammonia, a key part of nitrogen fertilizers, is central to sustaining global food production. However, its manufacture is also energy intensive: Ammonia production requires 2% of global energy to meet global demand. Approximately ...

Researchers in the College of Agriculture, Health and Natural Resources have developed a novel line of bovine embryonic stem cells, which have significant potential for a variety of new innovations, from lab-grown meat to ...

For decades, scientists have tried to answer a simple question: why be honest when deception is possible? Whether it is a peacock's tail, a stag's roar, or a human's résumé, signals are means to influence others by transmitting ...

An international collaboration involving researchers from the University of Innsbruck has developed a novel luminescent material that enables particularly robust and precise optical temperature sensing across an exceptionally ...
