Most people have heard about antibiotic-resistant germs. But how about antibiotic-resistant dust? A new Northwestern University study has found that an antimicrobial chemical called triclosan is abundant in dust—and linked to changes in its genetic makeup. The result is dust with organisms that could cause an antibiotic-resistant infection. “There is this conventional wisdom that says

Andrés Muñoz-Jaramillo of Southwest Research Institute and José Manuel Vaquero of the University of Extremadura have developed a new technique for looking at historic solar data to distinguish trustworthy observations from those that should be used with care. This work is critical to understanding the Sun’s past and future as well as whether solar activity

Industrial fisheries are starving seabirds like penguins and terns by competing for the same prey sources, new research from the French National Center for Scientific Research in Montpellier and the Sea Around Us initiative at the University of British Columbia has found. In a study published today in Current Biology, researchers found that annual seabird

Parrots are famously talkative, and a blue-fronted Amazon parrot named Moises—or at least its genome—is telling scientists volumes about the longevity and highly developed cognitive abilities that give parrots so much in common with humans. Perhaps someday, it will also provide clues about how parrots learn to vocalize so well. Morgan Wirthlin, a BrainHub post-doctoral

A study carried out in collaboration with the University of Birmingham has used an innovative approach to identify thousands of antibiotic resistance genes found in bacteria that inhabit the human gut. The human gut is home to trillions of microorganisms, mainly bacteria. Most of these are sensitive to antibiotics, but a significant number of bacteria

Bacteria can become insensitive to antibiotics by picking up resistance genes from the environment. Unfortunately for patients, the stress response induced by antibiotics activates competence in microorganisms, the ability to take up and integrate foreign DNA. Microbiologists from the University of Groningen (UG) and the University of Lausanne have now described a new mechanism by

Planning and self control in animals do not require human-like mental capacities, according to a study from Stockholm University. Newly developed learning models, similar to models within artificial intelligence research, show how planning in ravens and great apes can develop through prior experiences without any need of thinking. Researchers have previously suggested that ravens can

Genes that act late in life could explain why women have poorer health than men in older age, according to new research. Scientists have long wondered why older women are less healthy than older men, given that men at any given age are more likely to die than women (a puzzle known as the “male-female,

World’s first cannabis chromosome map reveals the plant’s evolutionary past and points to its future as potential medicine. THC and CBD, bioactive substances produced by cannabis and sought by medical patients and recreational users, sprung to life thanks to ancient colonization of the plant’s genome by viruses, U of T researchers have found. The finding

Until recently, scientists thought of viruses as mostly small infectious agents, tiny compared to typical bacteria and human cells. So imagine the surprise when biologist Jeff Blanchard and Ph.D. student Lauren Alteio at the University of Massachusetts Amherst, with others at the U.S. Department of Energy’s (DOE) Joint Genome Institute (JGI), discovered giant viruses—relatively speaking
