Polymetallic nodules and crusts cover many thousands of square kilometres of the world's deep-sea floor. They contain mainly manganese and iron, but also the valuable metals nickel, cobalt and copper as well as some of the high-tech metals of the rare earths. Since these resources could become scarce on land in the future - for example, due to future needs for batteries, electromobility and digital technologies - marine deposits are economically very interesting. To date, there is no market-ready technology for deep-sea mining.
A drug that lowers levels of the male hormone testosterone in the body reduces the risk of men with pedophilic disorder sexually abusing children, a study from Karolinska Institutet published today in the journal JAMA Psychiatry shows.
Boston, Mass. - With more than a million confirmed cases of COVID-19 in the United States, there is growing concern that low-income communities and racial/ethnic minorities may be disproportionately shouldering the burden of the pandemic. A new study, led by researchers at Beth Israel Deaconess Medical Center and published in the Journal of the American Medical Association (JAMA) suggests that substantial differences in COVID-19-related hospitalizations and deaths have emerged along racial and socioeconomic lines in New York City.
A first-of-its-kind nanoparticle-based in vivo imaging technique that may one day be used to help diagnose and even treat cancer has been developed by researchers collaborating from Michigan State, Johns Hopkins and Stanford universities.
The technique captures mechanical properties in living subjects that probe fundamental relationships between physics and in vivo (in a living organism) biology. The results are published in the journal Materials Today.
Crossing a 23-kilometer stretch of ocean from mainland Panama to Coiba, the largest offshore island in the Eastern Pacific, a group of intrepid biologists hoped to find species never reported there before. But in addition to discovering new species, the 2015 Coiba BioBlitz crew was surprised to find that capuchin monkeys spent so much time on the ground there.
THE construction industry can be transformed by adoption of the practices termed Building Information Modelling (BIM) and Lean Construction.
But research at the University of Huddersfield warns that the smaller firms who form the bedrock of the sector are in danger of missing out on cutting-edge techniques that lead to radical improvements in efficiency and productivity.
The research is described in an article published by the long-established and globally-respected Canadian Journal of Civil Engineering.
OAK BROOK, Ill. - An unprecedented collaboration among two medical societies and over 60 volunteer neuroradiologists has resulted in the generation of the largest public collection of expert-annotated brain hemorrhage CT images, according to a report published in Radiology: Artificial Intelligence. Leaders of the project expect the dataset to help speed the development of machine learning (ML) algorithms to aid in the detection and characterization of this potentially life-threatening condition.
Around the world, there are pools of water filled with nuclear waste waiting for their final resting place. This is waste that was created from decades of nuclear power generation, and the waste must be handled carefully.
In the United States, scientists are studying several solutions for disposing of these wastes. Phil Stauffer and researchers at Los Alamos National Labs have been working with the US Department of Energy and other national laboratories on one long-term, safe, disposal solution: salt.
Children are set to move more, improve their skills, and come up with their own creative tennis games with the launch of 'HomeCourtTennis', a new initiative to assist teachers and coaches with keeping kids active while at home.
Part one of the initiative, Games-making, will be introduced across Australia via a series of videos for teachers and coaches.
The free HomeCourtTennis content will support teachers in their physical education classes as they shift to distance learning, while coaches will use the material to remain connected to their players.
In the Eocene, some of the world's most important mountain ranges emerged and large climate changes took place that affected the future of the planet. In this era, about 50 million years ago, large groups of mammals and other animals also came , as did Daniellia clade, an array of legume plants which carry environmental relevance.
A drug already licensed for the treatment of breast and ovarian cancers is more effective than targeted hormone therapy at keeping cancer in check in some men with advanced prostate cancer, a major clinical trial reports.
Olaparib, a pill lacking the side effects of chemotherapy, can target an Achilles heel in prostate cancers with a weakness in their ability to repair damaged DNA. It is now on the verge of becoming approved as the first genetically targeted treatment for prostate cancer.
Like trains running on separate but parallel tracks, sometimes the forces of evolution can affect different species running along these tracks in very similar ways.
Take the evolution of a simple trait found in birds: foot feathering.
Lead researcher Chiara Bortoluzzi and colleagues at Wageningen University in the Netherlands, investigated the genetic basis of foot feathering, a phenotype that is observed in certain breeds of chicken.
In their search for new superhard compounds, researchers carried out a prediction of stable molybdenum borides and their crystal structures. They revealed that the highest borides contain four to five boron atoms per each molybdenum atom. The estimated Vickers hardness of MoB5 is 37-39 GPa, which makes it a potential superhard material. The study supported by Russian Science Foundation was published in The Journal of Physical Chemistry Letters.
In a policy brief published today in its namesake journal (DOI: 10.1111/jgs.16510), the American Geriatrics Society (AGS) offered a roadmap to guide federal, state, and local governments addressing COVID-19 concerns in an important but oft-overlooked arena: Assisted living facilities (ALFs).
New Haven, Conn. -- A new study led by Yale Cancer Center (YCC) researchers shows women with high-risk HER2-negative breast cancer treated before surgery with immunotherapy, plus a PARP inhibitor with chemotherapy, have a higher rate of complete eradication of cancer from the breast and lymph nodes compared to chemotherapy alone. The findings, part of the I-SPY clinical trial, were presented today at the American Association for Cancer Research (AACR) virtual annual meeting.
