Eggshells have led a team of scientists to a startling discovery — that as early as 18,000 years ago humans may have been hatching and raising cassowaries, considered one of the world's most dangerous...
We shuffle patients from cubicle to cubicle, hoping that we can squeeze just one more inI used to play a game with my children. How many ambulances are going to be waiting outside the emergency department today? I used to play it with my kids as I got a lift in for an early shift.“Three, Dad.” Continue...
A research team has been using high-intensity X-rays to observe a single catalyst nanoparticle at work. The experiment has revealed for the first time how the chemical composition of the surface of an individual nanoparticle changes under reaction conditions, making it more active. This study marks an important step towards a better understanding of real, industrial catalytic materials.
Extremely hot years will wipe out hundreds of thousands of tons of fish available for catch in a country's waters in this century, on top of projected decreases to fish stocks from long-term climate change, a new study predicts. Modelling a worst-case scenario where no action is taken to mitigate greenhouse gas emissions they projected a six per cent drop in the amount of potential catches per...
Researchers have utilized two-dimensional hybrid metal halides in a device that allows directional control of terahertz radiation generated by a spintronic scheme. The device has better signal efficiency than conventional terahertz generators, and is thinner, lighter and less expensive to produce.
Extremely hot years will wipe out hundreds of thousands of tonnes of fish available for catch in a country's waters in this century, on top of projected decreases to fish stocks from long-term climate change, a new UBC study projects.
British Columbia is subsidizing oil and gas well drilling on the same land it has promised to protect for caribou, new research has found.
A group of more than 20 current and former employees are accusing Jeff Bezos’ Blue Origin rocket ship company of being a toxic work environment and not adhering to proper safety protocols. The workers claim in an essay that there’s sexism at the Kent, Washington, company. The employees, led by former head of Blue Origin employee communications Alexandra Abrams, state that...
A DESY-led research team has been using high-intensity X-rays to observe a single catalyst nanoparticle at work. The experiment has revealed for the first time how the chemical composition of the surface of an individual nanoparticle changes under reaction conditions, making it more active. The team led by DESY's Andreas Stierle is presenting its findings in the journal Science Advances. This...
Researchers have found that aging produces significant changes in the microbiome of the human small intestine distinct from those caused by medications or illness burden.
After positive clinical trials for antiviral drug Molnupiravir, it joins other medicines that have shown promiseCoronavirus – latest updatesSee all our coronavirus coverageThe first clinical trial results showing a positive effect for a pill that can be taken at home has been hailed as a potential gamechanger that could provide a new way to protect the most vulnerable people from the worst...
An important lesson in the moral education of children could be as close as the book in their hands. Stories matter. And they can play a role in shifting the importance of particular moral values in young audiences, according to the results of a new study.
It's certainly easy to do, but not very useful, to stereotype outdoorsy people based on the types of recreation they choose. What kind of person takes a side-by-side vehicle up a dusty mountain road, for instance? And why? In reality, off-highway vehicle (OHV) recreation attracts a variety of people with diverse motivations for hitting the trail. And those motivations define, in part, the way they...
Citizens can play a major role in helping scientists to understand drying river networks, by reporting drying events in rivers and streams. To do so, DRYvER has created the DRYRivERS app, which citizens can use to map drying events. The collected data will improve scientific predictions of the future impacts of climate change in these ecosystems. Moreover, DRYRivERS will raise awareness of the...
Metal-rich near-Earth asteroids, or NEAs, are rare, but their presence provides the intriguing possibility that iron, nickel and cobalt could someday be mined for use on Earth or in Space.
A group of highly reactive compounds called persulfides have provoked great curiosity among biochemists, because of their role in nature, and how they interact with proteins to change their structure and function, affecting health, aging and disease processes.
Polymorphs are molecules that have different molecular packing arrangements despite identical chemical compositions. In a recent paper, researchers at GlaxoSmithKline (GSK) and the Cambridge Crystallographic Data Centre (CCDC) combined their proprietary (GSK) and published (CCDC) datasets to better train machine learning (ML) models to predict stable polymorphs to use in new drug candidates.
More than half of U.S. women will experience at least one urinary tract infection (UTI) in their lifetimes, while a quarter will have a subsequent infection. Recurrent urinary tract infections are defined as two or more infections in six months or three or more in a year.
A new study looks at how exposure to media content featuring specific moral values (care, fairness, loyalty and authority) might influence the weight kids place on those values. The main study showed that exposure to books emphasizing four separate moral values increased salience of their respective intuitions in early adolescents.
Researchers have developed a sensor that could diagnose a heart attack in less than 30 minutes, according to a new study.
A discovery of a new family of enzymes enriches the toolbox needed to engineer sulfur-containing compounds in the laboratory.
A team led by researchers has profiled in unprecedented detail thousands of individual cells sampled from patients' brain tumors. The findings, along with the methods developed to obtain those findings, represent a significant advance in cancer research, and ultimately may lead to better ways of detecting, monitoring and treating cancers.
COVID-19 may bring high risks of severe disease and death in many patients by disrupting key metabolic signals and thereby triggering hyperglycemia, according to a new study.
