Optical security: Tunable-resonator upconverted emission color printing

Scientists from SUTD have developed a plasmonic upconversion optical security device that displays an ultrahigh resolution color print under white light, while revealing different luminescent information under infrared illumination. The device uses monolayers of upconversion nanophosphors to achieve true color printing.

Machine learning overtakes humans in predicting death or heart attack

A study by the European Society of Cardiology found that machine learning algorithms can accurately predict heart attacks and deaths with over 90% accuracy. By analyzing 85 variables from imaging data, the algorithm identified patterns correlating to death and heart attack, surpassing human performance.

Maternal microbes mediate diet-derived damage

Research found that maternal microbes can impair the gut barrier during pregnancy, leading to increased inflammatory markers and altered placental development. A high-fat diet exacerbated these effects, impacting fetal intestinal development and potentially affecting metabolism after birth.

Teachers predict pupil success just as well as exam scores

Teacher assessments were found to correlate strongly with exam scores, predicting around 90% of differences between pupils in exam performance at GCSE and A-level. The study suggests that relying on teacher assessments could be a more effective way to monitor progress and reduce the impact of high-stakes exams.

Autophagy in dendritic cells helps anticancer activity

Researchers found that autophagy in dendritic cells supports T-cell anticancer activity by regulating receptor CD36. This process enhances the phagocytosis of apoptotic tumor cells while restricting T-cell activation.
