The growing rate of ice melt in the Arctic due to rising global temperatures has opened up the Northwest Passage (NWP) to more ship traffic, increasing the potential risk of an oil spill and other environmental disasters. A new study published in the journal Risk Analysis suggests that an oil spill in the Canadian Arctic could be devastating--especially for vulnerable indigenous communities.

An integrated design optimisation and fabrication workflow opens new opportunities for tailoring the mechanical properties of soft machines.

"Snowball Earth" is the most extreme climate event in Earth's history, when it was completely engulfed in ice.The theory of its existence has faced two challenges - how life survived and variations in rock formations from the time implying changes to the climate cycle.New study shows that changes to Earth's orbit caused the ice sheets to advance and retreat, providing ice-free 'oases' for animal life and explaining variations in rock formations.

Researchers from IDIBELL and the University of Barcelona have described that neurons derived from Parkinson's patients show impairments in their transmission before neurodegeneration.For this study, it has been used dopaminergic neurons differentiated from patient stem cells as a model.

Screens may be larger on smartphones now, but nearly every other component is designed to be thinner, flatter and tinier than ever before. The engineering requires a shift from shapely, and bulky lenses to the development of miniaturized, two-dimensional metalenses. They might look better, but do they work better? A team of Japan-based researchers says yes, thanks to a solution they published on July 7th in Applied Physics Express, a journal of the Japan Society of Applied Physics.

An international research team has found that despite being the world's leading cause of pain, disability and healthcare expenditure, the prevention and management of musculoskeletal health, including conditions such as low back pain, fractures, arthritis and osteoporosis, is globally under-prioritised and have devised an action plan to address this gap.

High-risk neuroblastoma is an aggressive childhood cancer with poor treatment outcomes. Despite intensive chemotherapy and radiotherapy, less than 50 percent of these children survive for five years. While the genetics of human neuroblastoma have been extensively studied, actionable therapeutics are limited.

Opioid prescribing preferences and practices among surgical residents and faculty differ, according to a new study published in the journal Surgery by CU Department of Surgery researchers.

Having multiple chronic health conditions and living in a rural area were the top two factors affecting increased healthcare system contact among older patients with bladder cancer, a research team has found.

When an external magnetic field or mechanical voltage is applied, the resulting material can create an electric charge on the surface. For instance, these properties can be used in biomedicine in order to create controlled interfaces that have the potential to increase the number and change stem cells into neurons or such. In the future, researchers will be able to use this technology in tissue engineering.

Australian scientists researching how our immune system responds to COVID-19 have revealed that those infected by early variants in 2020 produced sustained antibodies, however, these antibodies are not as effective against contemporary variants of the virus.

Scientists at KAIST have fabricated a laser system that generates highly interactive quantum particles at room temperature. Their findings, published in the journal Nature Photonics, could lead to a single microcavity laser system that requires lower threshold energy as its energy loss increases.

In two recent articles published in Schizophrenia Bulletin, Sharon Hunter, PhD, an associate professor in the CU School of Medicine Department of Psychiatry, and M. Camille Hoffman, MD, MSc, an associate professor in the CU School of Medicine Department of Obstetrics and Gynecology, have uncovered a potential link between choline deficiency in Black pregnant women in the United States and increased risk of developmental issues that can evolve into mental illness later in children's lives.

Cheap to produce and long to degrade, plastic was once a manufacturing miracle. Now, plastic is an environmental plague, clogging landfills and choking waterways. A Japan-based research team has turned back to nature to develop an approach to degrading the stubborn substance.

A new study of lithium production in a classical nova found a production rate of only a couple of percent that seen in other examples. This shows that there is a large diversity within classical novae and implies that nova explosions alone cannot explain the amount of lithium seen in the current Universe. This is an important result for understanding both the explosion mechanism of classical novae and the overall chemical evolution of the Universe.

Molecules from the same family as the anti-coagulant drug heparin may interfere with the ability of the COVID-19 virus's spikes to bind to human cells. This could be used to treat people with severe effects of the virus and any emerging variants.

Mount Sinai researchers have uncovered the complex cellular mechanisms of Ebola virus, which could help explain its severe toll on humans and identify potential pathways to treatment and prevention.

A recent study has shown that the shape of cell-derived nanoparticles, known as "extracellular vesicles" (EVs), in body fluids could be a biomarker for identifying types of cancer. In the study, scientists successfully measured the shape distributions of EVs derived from liver, breast, and colorectal cancer cells, showing that the shape distributions differ from one another.

Anti-androgen therapy is commonly used to treat patients with advanced prostate cancer at stages where the disease has spread to the bones. However, new research has found that anti-androgen treatment can actually facilitate prostate cancer cells to adapt and grow in the bone tumour microenvironment model, which has been developed by QUT biomedical scientists led by Dr Nathalie Bock.

Researchers at the IBS Center for Quantum Nanoscience at Ewha Womans University (QNS) have shown that dysprosium atoms resting on a thin insulating layer of magnesium oxide have magnetic stability over days. In a study published in Nature Communications they have proven that these tiny magnets have extreme robustness against fluctuations in magnetic field and temperature and will flip only when they are bombarded with high energy electrons through the STM-tip.
