The future of Samoa's electricity system could go green, a University of Otago study has shown.

Pacific Island nations are particularly susceptible to climate change and face high costs and energy security issues from imported fossil fuels.

For these reasons many Pacific Island nations have developed ambitious 100 per cent renewable energy targets. However, they have not been subject to rigorous peer-reviewed studies to help develop these targets and pathways for achieving them in the same way as more developed countries.

Cambridge, MA ¬- Astronomers at the Center for Astrophysics | Harvard & Smithsonian have helped detect the clear presence of a moon-forming region around an exoplanet -- a planet outside of our Solar System. The new observations, published Thursday in The Astrophysical Journal Letters, may shed light on how moons and planets form in young stellar systems.

Adults and children with COVID-19 who have a history of malnutrition may have an increased likelihood of death and the need for mechanical ventilation, according to a study published in Scientific Reports.

Malnutrition hampers the proper functioning of the immune system and is known to increase the risk of severe infections for other viruses, but the potential long-term effects of malnutrition on COVID-19 outcomes are less clear.

Leesburg, VA, July 22, 2021--According to ARRS' American Journal of Roentgenology (AJR), the standardized non-invasive clear cell likelihood score (ccLS)--derived from MRI--correlates with the growth rate of small renal masses (cT1a,

DALLAS - July 20, 2021 - UT Southwestern researchers report the first structural confirmation that endogenous - or self-made - molecules can set off innate immunity in mammals via a pair of immune cell proteins called the TLR4?MD-2 receptor complex. The work has wide-ranging implications for finding ways to treat and possibly prevent autoimmune diseases such as multiple sclerosis and antiphospholipid syndrome.

In one out of every six local authorities, rates of hunger are more than 150 per cent (one and a half times) the national average. Shockingly, in one in 10 local authorities, the rate is almost double, according to new research by the University of Sheffield.

Persistence may be the key when quitting smoking using an electronic nicotine delivery system (ENDS), commonly known as vaping, a University of Otago study found.

Researchers found people attempting to switch from cigarettes to ENDS reported highly varied smoking and ENDS use. They recommend people persist in their attempts to transition away from smoking, even if their progress feels slow and uncertain.

A new quantitative study suggests people seeking asylum are more likely to experience mental health deterioration as they spend more time living in refugee camps, backing up qualitative evidence from aid organisations.

Researchers from the School of Biomedical Engineering & Imaging Sciences at King's College London have automated brain MRI image labelling, needed to teach machine learning image recognition models, by deriving important labels from radiology reports and accurately assigning them to the corresponding MRI examinations. Now, more than 100,00 MRI examinations can be labelled in less than half an hour.

Published in European Radiology, this is the first study allowing researchers to label complex MRI image datasets at scale.

An international research team has come up with an innovative method for metal recovery from industrial waste. The new method allows the simultaneous recovery of multiple metals from waste oxides in a single process. This novel route will lower the burden on waste storage facilities with significant contributions to the economic and environmental sustainability of industrial waste management. The study was published in Journal of Environmental Management.

Alexandria, Va., USA - Muthuthanthrige Cooray, Tohoku University, Sendai, Japan, presented the oral session "Oral and General Health Associations Using Machine Learning Prediction Algorithms" at the virtual 99th General Session & Exhibition of the International Association for Dental Research (IADR), held in conjunction with the 50th Annual Meeting of the American Association for Dental Research (AADR) and the 45th Annual Meeting of the Canadian Association for Dental Research (CADR), on July 21-24, 2021.

To be useful, drones need to be quick. Because of their limited battery life they must complete whatever task they have - searching for survivors on a disaster site, inspecting a building, delivering cargo - in the shortest possible time. And they may have to do it by going through a series of waypoints like windows, rooms, or specific locations to inspect, adopting the best trajectory and the right acceleration or deceleration at each segment.

Algorithm outperforms professional pilots

Alexandria, Va., USA - Walter Siqueira, University of Saskatchewan, Saskatoon, Canada, presented the poster "Self-collected Saliva and Courier Service - A Feasible Diagnostic Strategy for COVID-19" at the virtual 99th General Session & Exhibition of the International Association for Dental Research (IADR), held in conjunction with the 50th Annual Meeting of the American Association for Dental Research (AADR) and the 45th Annual Meeting of the Canadian Association for Dental Research (CADR), on July 21-24, 2021.

To reach the target of carbon neutral, a transition from fossil energy to renewable energy generation is indispensable. Photovoltaic technology is considered as one of the most prominent sources of renewable energy. For decades, about 90% of global solar cell market has been dominated by silicon solar cells. Although the price of silicon solar panels decreases year by year, it is a big challenge to significantly reduce its manufacturing cost further. Hence, next-generation photovoltaic technologies are in urgent need of new materials and novel techniques.

PHILADELPHIA--Investing in structural home repairs in historically segregated, low-income, Black and Latino neighborhoods has been associated with reduced crime rates.
