Emerging Salmonella variety in dairy cows found to worsen antimicrobial resistance
A study of more than 5,000 Salmonella bacteria isolated over 15 years from dairy cattle samples in the Northeast reveals a significant increase in resistance to the antimicrobial medications ampicillin, florfenicol and ceftiofur......»»
Brown bears digging up artificial forests, study shows
Brown bears foraging for food in the Shiretoko Peninsula of Hokkaido, Japan, have been disrupting tree growth in artificial conifer forests, according to a new study published in Ecology. Researchers compared soil and tree samples from human-forested.....»»
Antimicrobial-resistant E. coli found in dogs with diarrhea
A team of Chinese veterinary researchers has found high levels of antimicrobial-resistant Escherichia coli in dogs with diarrhea. In their study, published in the open access journal PLOS ONE, the group tested fecal samples from 185 dogs with diarrhe.....»»
Seeing the wood for the trees: How archaeologists use hazelnuts to reconstruct ancient woodlands
If we could stand in a landscape that our Mesolithic ancestors called home, what would we see around us? Scientists have devised a method of analyzing preserved hazelnut shells to tell us whether the microhabitats around archaeological sites were hea.....»»
How did a tiny bee get to French Polynesia? Eight new species help solve a scientific mystery
In 1934, American entomologist Elwood Zimmerman, then an undergraduate student at Berkeley, participated in the "Mangarevan expedition" to Polynesia. Among the samples he collected were three tiny (4 mm long), orange-brown solitary bees found on tahe.....»»
Microplastics present in muscles, intestines of South East Queensland sharks
Researchers have discovered not only microplastics but also a higher abundance of cellulose-based fibers in the intestine samples of four apex shark species caught off the coast of South East Queensland (SEQ)......»»
Mars samples project looms large in final spending talks
A complex project aimed at retrieving rock and dirt samples from Mars has long been a top priority for NASA, with proponents arguing the mission could answer the age-old question of whether life once existed on the red planet......»»
NASA"s final tally shows spacecraft returned double the amount of asteroid rubble
NASA finally has counted up all the asteroid samples returned by a spacecraft last fall—and it's double the rubble return goal......»»
Application of ultrasound found to greatly speed up motility of human sperm
A team of engineers at Monash University in Australia has found that exposing human sperm to ultrasound can cause them to swim faster. In their study, published in the journal Science Advances, the group exposed human semen samples to ultrasonic wave.....»»
Unlocking the full potential of Auger electron spectroscopy
Auger electron spectroscopy (AES) is an incredibly useful technique for probing material samples—but current assumptions about the process ignore some of the key time-dependent effects it involves. So far, this has resulted in overly-simplified cal.....»»
By growing animal cells in rice grains, scientists dish up hybrid food
From lab-grown chicken to cricket-derived protein, these innovative alternatives offer hope for a planet struggling with the environmental and ethical impacts of industrial agriculture. Now, Korean scientists add a new recipe to the list—cultured b.....»»
Natural gas flare samples collected by aircraft reveal high variation in nitrogen oxides emission estimates
Natural gas flaring, or burning, is commonly used in parts of the United States to dispose of the gas byproduct from oil extraction. The flare's combustion converts hydrocarbons to carbon dioxide and water, which lessens the climate impact and reduce.....»»
How air pollution harms pollination
Pollination, the transfer of pollen grains from the male to the female organs, is an essential part of reproduction for the majority of plants. For many of these plants, this transfer is carried out by insects in search of food—this is known as ins.....»»

Research samples collected over decades at a prestigious Swedish medical university have been destroyed after a freezer malfunctioned over the Christmas holidays, the university said on Monday......»»
Orbital resonance: The striking gravitational dance done by planets with aligning orbits
Planets orbit their parent stars while separated by enormous distances—in our solar system, planets are like grains of sand in a region the size of a football field. The time that planets take to orbit their suns have no specific relationship to ea.....»»
Rare 3D fossils show that some early trees had forms unlike any you"ve ever seen
In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. But now, researchers reporting in the journal Current Biology descri.....»»
"Flawed" material resolves superconductor conundrum
