How Bolsonaro's statements destroyed the rainforest
Former Brazilian President Jair Bolsonaro contributed to deforestation through statements opposing forest conservation, according to an international study led by the University of Bonn. The study found that destruction of the Amazon rainforest accelerated when Bolsonaro and his ministers posted messages opposing forest conservation on Twitter. Brazil's environmental authorities were greatly weakened during Bolsonaro's presidency, but the analysis suggests that even a perceived low risk of punishment was a driver of deforestation. The researchers estimate that the statements contributed to the destruction of up to 1,700 square kilometers (660 square miles) of forest—almost double the area of Berlin. The results were published in The Journal of Politics.

When microbial DNA is scarce, new profiling method helps separate genuine signals from contamination
In acute, life-threatening infections, rapidly characterizing the microorganisms in a patient sample can help guide diagnosis and treatment. Computational methods known as taxonomic profilers can analyze metagenome sequencing data generated from the microorganisms' genomic information and compare it with reference genomes of individual microorganisms. However, taxonomic profilers are still under development and are not yet in common use. Current methods can produce false-positive results or inaccurate abundance estimates.

Plasma treatment helps reveal how molecular coatings dope silicon
Controlling dopant concentration near the silicon surface is increasingly important for ultrashallow junctions and nanoscale devices. Mixed monolayer doping (MMLD) offers a surface-chemistry-based approach in which dopant-containing molecules are mixed with nondopant molecules to tune the amount of dopant available at the silicon surface before thermal diffusion.

Two-color glowing molecule could make wind tunnel tests more accurate
Most sensors can measure only one thing at a time, like a thermometer for temperature or a pressure gauge for pressure. Measuring two properties accurately from the same surface at the same moment usually means using two separate instruments—adding cost and complexity to the process.

Espionage boosted East Germany's economic output by 7.4%
East Germany's espionage activities in the West boosted the country's economic output by 7.4%. Value added in manufacturing alone increased by 22.3% through industrial espionage, equivalent to 20.2 billion East German marks or approximately 4.1 billion euros at 2020 prices.

Hydrogen's distant glow opens new way to investigate dark energy
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has shown for the first time that it can detect the faint glow of hydrogen gas from deep in the universe's past using only its own data.

AI news coverage reveals hierarchy of innovators, regulators and overlooked regions
Analyzing more than 43,000 English-language newspaper articles, a new study reveals a highly stratified narrative about AI in which the news media allocate authority unequally, reinforcing the technology's prominent role in contemporary life.
