Treating preterm infants with antibiotics for more than 20 months appears to promote the development of multidrug-resistant gut bacteria, suggests a study funded by the National Institutes of Health. The research appears in Nature Microbiology.
BUFFALO, N.Y. -- Superhard materials can slice, drill and polish other objects. They also hold potential for creating scratch-resistant coatings that could help keep expensive equipment safe from damage.
Now, science is opening the door to the development of new materials with these seductive qualities.
Researchers from Chalmers University of Technology and Politecnico di Milano have identified a crucial new aspect of charge density modulations in cuprate high critical temperature superconductors. They have identified a new electron wave which could help reveal some of the mysteries about superconducting materials. The findings are published in the journal Science.
Doctors have found that children who have been in Intensive Care Units (ICUs) for sepsis have a significantly increased risk of Post-Traumatic Stress Disorder (PTSD), with around 1/3 showing PTSD symptoms. In some young people, these may persist for years following discharge. There is some evidence that these children have altered immune responses during their stay in ICU and this may be a risk factor for later PTSD symptom development, but this needs to be confirmed.
WASHINGTON -- Regular screening mammograms are unlikely to benefit women 75 and older who have chronic illnesses such as cardiovascular disease or diabetes. New data suggest they would likely die due to other health conditions before they developed breast cancer.
That is the finding of a new study based on data from more than 220,000 women that was published September 6, 2019, in JNCI.
EAST LANSING, Mich. - Grasslands make up more than 40% of the world's ice-free land and have sustained humanity and thousands of other species for eons. In addition to providing food for cattle and sheep, grasslands are home to animals found nowhere else in the wild, such as the bison of North America's prairies or the zebras and giraffes of the African savannas. Grasslands also can hold up to 30% of the world's carbon, making them critical allies in the fight against climate change.
One of the first studies of its kind focusing on South African children's language ability and mental health outcomes, has found clear evidence for a link between low language ability and depression in young people.
The study, published today in the journal PLOS One from researchers at the University of Bath (UK) and Stellenbosch University (South Africa) studied language ability and outcomes for 200 13-year-olds in Khayelitsha - a semi-urban, impoverished township outside Cape Town.
By coupling magnetic behavior to a superconducting circuit, Argonne scientists pave the way for quantum information systems.
Quantum computing promises to revolutionize the ways in which scientists can process and manipulate information. The physical and material underpinnings for quantum technologies are still being explored, and researchers continue to look for new ways in which information can be manipulated and exchanged at the quantum level.
Researchers have engineered gold-based molecules that target cancer cells and leave healthy cells unharmed, in a critical step towards precision cancer drugs with fewer toxic side effects.
Pre-clinical studies have shown the molecules were up to 24 times more effective at killing cancer cells than the widely used anti-cancer drug cisplatin and were also better at inhibiting tumour growth.
Humans can visually perceive the motion of a small object better than that of a large one. By contrast, according to a study reported in the journal Current Biology on September 5, babies under 6 months of age are better at seeing the movement of large objects than small objects.
Hannibal. Voldemort. Skeletor and Gargamel. It's hard to imagine any nefarious villain having redeeming qualities. But what if someone were to tell you that the Joker is a monster only because he learned the behavior from people around him and it's possible that, one day, he might change for the better?
A new study out of Columbia University suggests that the way we perceive others' bad behavior -- as either biological and innate or potentially changeable -- impacts our willingness to cut them some slack.
Wildfires are widespread across the globe. They occur in places wherever plants are abundant -- such as the raging fires currently burning in the Brazilian Amazon. Such biomass burning (BB) can be an environmental calamity.
The smoke from BB events produces large amounts of aerosol particles and gases. These emissions can cause major problems for visibility and health, as well as for local and global climate.
A study by an assistant professor at The University of Texas at Arlington published in the Journal of Marketing shows that marketers of relatively high-priced products should consider keeping prices high, as many consumers associate high price with high quality.
Narayanan Janakiraman, UTA assistant professor of marketing in the College of Business, said these same consumers equate lower prices with lower quality.
When Kīlauea Volcano erupted in 2018, it injected millions of cubic feet of molten lava into the nutrient-poor waters off the Big Island of Hawai'i. The lava-impacted seawater contained high concentrations of nutrients that stimulated phytoplankton growth, resulting in an extensive plume of microbes that was detectable by satellite.
The dinosaur, whose nearly complete skeleton was unearthed from 72 million year old marine deposits in Mukawa Town in northern Japan, belongs to a new genus and species of a herbivorous hadrosaurid dinosaur, according to the study published in Scientific Reports. The scientists named the dinosaur Kamuysaurus japonicus.
