A new study found that more than 30% of hospital patients who have a heart attack complicated by low blood pressure undergo an aggressive treatment, despite the existence of a less aggressive approach called a 'culprit-only' strategy. This strategy places stents only in the blocked blood vessels that caused the heart attack.
The James Webb Space Telescope successfully completed a critical ground segment test, demonstrating the complete end-to-end flow from planning science observations to downlinking data. This milestone validates the observatory's ability to respond to commands and function in space.
Researchers used data gathered before a 2017 deadly landslide in Greenland to demonstrate the effectiveness of deep learning in predicting seismic events. The study found weak but repetitive rumblings that accelerated over time, leading to the landslide, which could be detected by AI.
Soil loss due to water runoff is projected to increase significantly by 2070, with potential losses of over 28 billion metric tons annually. Sustainable land cultivation practices can mitigate this threat and ensure food security for the world's population.
New research by the University of Minnesota and the University of Washington reveals that additional ICU beds and non-ICU beds filled by COVID-19 patients result in more deaths. The study found that for every six additional ICU beds or seven additional non-ICU beds, one additional COVID-19 death occurs over the following week.
A comprehensive database of 33,242 unique viral populations in the human digestive system has been assembled by Ohio State University scientists. This discovery reveals a complex relationship between viruses and bacteria in the gut, with higher diversity associated with healthier individuals.
Research presented at the European Respiratory Society International Congress shows that babies exposed to levels of air pollution within EU standards develop poorer lung function as children and teenagers. Long-term exposure to air pollution is also linked to a higher risk of developing asthma in adults, according to a second study.
Scientists demonstrate efficient separation of valley exciton emission of a WS2 monolayer using two-dimensional all-dielectric PhC slabs without in-plane inversion symmetry. The delocalized Bloch modes play a critical role in separating and enhancing directional valley exciton emission.
Researchers developed a world-first technique to improve cancer treatments by analyzing fresh patient tumour biopsies within 30 minutes of collection. The 'Drug uptake in ex Vivo tumours' technique helps pharmaceutical and technology companies design future cancer drugs.
A new study emphasizes the importance of involving local communities in global forest restoration efforts, which could provide benefits to millions of people living on lands suitable for forest restoration. The research highlights opportunities for tropical countries to remove atmospheric carbon, promote biodiversity conservation, and ...
A comprehensive review of animal and cellular models of SARS-CoV-2 infection and COVID-19 highlights the importance of understanding underlying diseases in predicting mortality. The study identifies key factors, including age, male sex, social deprivation, and chronic conditions, that increase the risk of severe disease.
