Think you might have COVID? Wait two days to test

A new mathematical model suggests that waiting two days after symptoms arise for rapid COVID tests can increase accuracy by reducing false negatives. The model also recommends a 'test-to-exit' strategy to prevent infections and minimize inconvenience, which may be more effective than the five-day isolation policy.

Study: Teacher perceptions of chronically absent young students may add to the challenges of missing school

A new study found that early elementary school teachers report feeling less close to chronically absent students and viewing them less positively. Teachers in kindergarten, first grade, and second grade also perceive these students as having worse interpersonal skills and academic difficulties, despite not causing trouble in the classr...

Improving transformation frequency in maize

Researchers at VIB-UGent Center for Plant Systems Biology have developed a new method to improve maize transformation frequency using ternary vectors and morphogenic regulators. By combining these technologies, they achieved a 20-fold increase in transformed plants, paving the way for more effective research and innovative applications.

Social media use is associated with more frequent vaccination

Researchers found a consistent positive relation between social media use and vaccination across all major political parties. For Democrats, social media exposure predicted greater vaccine uptake due to increased information about new pathogens. For Republicans, believing others were vaccinated was the key factor.
