The association between the workload of emergency physicians and the outcomes of acute myocardial infarction: a population-based study
Abstract Acute myocardial infarction (AMI) is the second leading cause of mortality in Taiwan. The correlation between the workload of emergency physicians and the outcome of AMI remains unknown. To determine the effects of the workload of emergency physicians on the outcomes of AMI. We included 17 661 patients (age > 18 years) with STEMI undergoing PCI, who visited…

New thermal decomposition pathway for TATB
Abstract Understanding the thermal decomposition behavior of TATB (1,3,5-triamino-2,4,6-trinitrobenzene) is a major focus in energetic materials research because of safety issues. Previous research and modelling efforts have suggested benzo-monofurazan condensation producing H2O is the initiating decomposition step. However, early evolving CO2 (m/z 44) along with H2O (m/z 18) evolution have been observed by mass spectrometric…

Evelyn Fox Keller (1936–2023), philosopher who questioned gender roles in science
Credit: Rick Friedman/Corbis via Getty Evelyn Fox Keller achieved prominence for her studies on gender and science, the role of language in shaping how we see and study the world and her analysis of key concepts in modern biology, such as the gene. Keller tackled the fundamental question of how scientific knowledge is created and…

Physical infrastructure and global capacity are both needed to fight biodiversity loss
A recent editorial in this journal1 highlighted how equity and access are essential to using the unique power of herbarium collections for understanding plant biology and mitigating environmental change. Many large collections, such as those held at the Royal Botanic Gardens, Kew (RBG Kew), are global in scope and of particular value because of the…

Spider silk research leads to new microphone patent
The human ability to notice the world around us is made possible by our sense organs — eyes, ears, nose, skin and tongue — which are so efficient that most people don’t consciously think about them. Others, like Distinguished Professor of Mechanical Engineering Ron Miles, have always had a “sense” for them. “I have been…

World’s weirdest: Meet the purple frog flaunting nature’s most bizarre backside
You could say that the purple frog resembles a turtle without its shell. That’s what the good people of Idukki in Kerala say. Or you could say that this amazing amphibian looks like a bruised, bloated beanbag with beady eyes and a bootylicious backside. That’s what I say. Evolution rightly has no respect for conventional…

Modular chimeric cytokine receptors improve CAR T–cell therapy for solid tumors
The St. Jude group replaced the extracellular domain of different cytokine receptors with leucine zippers to create constitutively active receptors. CAR T cells expressing any of these chimeric cytokine receptors had superior antitumor activity against multiple types of cancer in both cell lines and mouse models compared to conventional CAR T cells. While the chimeric…
