Researchers have developed a model that could boost investment in farm-based sustainable energy projects by allowing investors to more accurately predict whether a project will turn a profit. The model improves on earlier efforts by using advanced computational techniques to address uncertainty.
A place-based payroll tax incentive can be effective in stimulating employment in remote and underdeveloped regions, helping to address regional inequalities, according to a new UCL and University of Oslo study.
The way research in bioprinting will be taken forward has been laid out in a roadmap for the field.
Published today in IOP Publishing's Biofabrication, leading researchers define the status, challenges and opportunities in the field, and forecast the required advances in science & technology to overcome the challenges to a range of bioprinting techniques and applications.
In the roadmap:
Hospitals, doctors and Medicare Advantage insurance plans that care for some of the most vulnerable patients are not reimbursed fairly by Medicare, according to recent findings in JAMA.
Health insurance costs weigh heavily on the minds of many middle-aged adults, and many are worried for what they'll face in retirement or if federal health policies change, according to a new study just published in JAMA Network Open.
A population of microorganisms living in our intestine, known as the gut microbiota, plays a crucial role in controlling our metabolism and reducing the risk of conditions such as obesity and diabetes.
The Clostridium difficile pathogen takes its name from the French word for "difficult." A bacterium that is known to cause symptoms ranging from diarrhea to life-threatening colon damage, C. difficile is part of a growing epidemic of concern for the elderly and patients on antibiotics.
Outbreaks of C. difficile-infected cases have progressively increased in Western countries, with 29,000 reported deaths per year in the United States alone.
Chronic pain, or inflammation, is believed to be one of the major factors in the onset of major depressive disorder. Therefore, to better understand what happens physiologically during depression, scientists have long studied several metabolic processes or "pathways" related to inflammation. One of these pathways, called the kynurenine pathway, is the principal pathway involved in metabolizing the amino acid tryptophan.
Scientists at Tokyo Institute of Technology have shown that copper oxide particles on the sub-nanoscale are more powerful catalysts than those on the nanoscale. These subnanoparticles can also catalyze the oxidation reactions of aromatic hydrocarbons far more effectively than catalysts currently used in industry. This study paves the way to better and more efficient utilization of aromatic hydrocarbons, which are important materials for both research and industry.
A calf was born from an embryo lacking cells which form a large part of the placenta, providing new insight into the regenerative capacity of mammalian embryos.
Mammalian development starts from a single cell -- a fertilized egg. The egg goes through multiple cell divisions to increase its cell numbers and then starts forming a sphere-like structure with a cavity inside, called the blastocyst. The blastocyst consists of two types of cells, the inner cell mass (ICM) and the trophectoderm (TE), which develop into an embryo proper and a large part of the placenta, respectively.
The novel coronavirus 2019-nCoV is making headlines worldwide. Since there is no specific therapy against it, the prevention of infection is of particular importance in order to stem the epidemic. Like all droplet infections, the virus can spread via hands and surfaces that are frequently touched.
With the deployment of 5G networks throughout 2020, scientists are now focusing their research attentions on 6G communications. This research will need to be human-centric, according to KAUST postdoctoral fellow Shuping Dang.
Dang and his colleagues examined the potential applications and challenges of 6G communications in a study published in Nature Electronics. They found that 6G communications will need to be more secure, protect people's privacy, be ubiquitously accessible and affordable, and safeguard users' mental and physical well-being.
Everyone knows that eating fish is good for you, in part because of the healthy omega-3 fatty acids that it contains.
Several of these fatty acids are essential in human diets, especially when it comes to infant development and reducing cognitive decline in adults.
But dwindling fish stocks worldwide, combined with a growing population, mean that a substantial number of people on the planet don't get enough of these essential nutrients, a new study shows.
As an important branch of quantum computation, topological quantum computation has been drawing extensive attention for holding great advantages such as fault-tolerance. Topological quantum computation is based on the non-Abelian braiding of quantum states, where the non-Abelian braiding in the field of quantum statistics is highly related to the non-locality of the quantum states.
BUFFALO, N.Y. -- Some 4,ooo years ago, a tiny population of woolly mammoths died out on Wrangel Island, a remote Arctic refuge off the coast of Siberia.
They may have been the last of their kind anywhere on Earth.
To learn about the plight of these giant creatures and the forces that contributed to their extinction, scientists have resurrected a Wrangel Island mammoth's mutated genes. The goal of the project was to study whether the genes functioned normally. They did not.
