Generation of harmful slow electrons in water is a race between intermolecular energy decay and proton transfer
When high-energy radiation interacts with water in living organisms, it generates particles and slow-moving electrons that can subsequently damage critical molecules like DNA. Now, Professor Petr Slavíček and his bachelor's student Jakub Dubský from UCT Prague (University of Chemistry and Technology, Prague) have described in detail one of the key mechanisms for the creation of these slow electrons in water, a process known as Intermolecular Coulombic Decay (ICD). Their powerful mathematical model successfully explains all the data from complex laser experiments conducted at ETH Zurich (Hans-Jakob Woerner team).

Reduction in costs of fentanyl production found to have long-term implications for illegal opioid supply industry
The spread of illegally manufactured fentanyl has driven overdose deaths to unprecedented levels in the United States and Canada. It has also changed the production function for drug traffickers, most notably by radically reducing the costs of raw materials for those producing illegal opioids.

Machine learning helps identify 'thermal switch' for next-generation nanomaterials
Imagine being able to program materials to control heat like you can control a light with a dimmer switch. By simply squeezing or stretching the materials, you can make them hotter or colder.

Discovery of brain parasite's unique control protein offers hope for better toxoplasmosis treatments
Rajshekhar Gaji was staring at something that should not exist. Under his microscope, parasites that should have been thriving were instead dying—completely unable to survive without a protein his lab had managed to switch off.

Undergrads uncover conserved copper-binding gene cluster in marine bacteria
This fall, 20 Georgia Tech students published a paper—the culmination of work done during a semester-long laboratory course. During the semester, students analyzed genomes sequenced from marine samples collected in Key West, Florida—doing hands-on original bioinformatics research on par with graduate students and working with bioinformatics tools to explore drug discovery potential.

European voters say no to tariffs
There is no popular support for imposing trade tariffs in Europe—not even in response to Trump's trade policies. This is according to a new study based on responses from 5,500 people in Germany and the UK.

Opinion: Climate change divides the innovators from the defenders of the status quo
"The European Green Deal is something we owe to our children because we do not own this planet." These words date back to a few days before Christmas 2019. They defined Ursula Von Der Leyen's first presidency of the European Commission but belong to what now seems like a different era.
