NASA Laser Terminal enhances views during Artemis II mission‎

Millions of people watched the historic launch of Artemis II and were captivated by the mission's 10-day journey around the moon as NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen ventured farther into space than any human before. Part of the public's ability to experience the mission in high-definition was due to laser communications.

Widespread genetic exchange in disease-causing parasites revealed‎

Mississippi State University biologist Matthew W. Brown is part of an international research team whose latest findings, published this spring in the Proceedings of the National Academy of Sciences, are reshaping scientific understanding of how parasitic organisms evolve and ultimately spread disease.

Mechanochemistry simplifies synthesis of challenging conductive organic molecules‎

Mechanochemistry is a growing field for chemical reactions that proceed in the solid state in the absence, or with minuscule amounts, of solvent added. For decades, solvents have been considered conventional for the progression of modern chemistry; nonetheless, researchers are increasingly demonstrating that mechanochemistry can synthesize complex molecules more effectively. With more progress, mechanochemistry could alleviate solvent-related environmental and financial burdens in chemical industries.

Stealth switch in tuberculosis enzyme could open route to drug-resistant treatment‎

Recent research published in Communications Biology marks an advance in structural biology by enhancing understanding of protein regulation mechanisms in Mycobacterium tuberculosis (Mtb), a global health threat. The team led by the University of Melbourne combined several advanced techniques at the Australian Synchrotron and the National Deuteration Facility to reveal the hidden allosteric mechanism that activates a key enzyme, ICL2.

Q&A: How the legal opium market shaped global trade—and led to an opioid crisis‎

The rare earths so essential to our modern technology have become a new diplomatic weapon—used to leverage influence and wield power, reshape global alliances, and exert economic dominance. For centuries, says Boston University historian Benjamin R. Siegel, opium was used in much the same way.

A leading journal finds that AI is flooding academic publishing with lower quality work‎

Artificial intelligence can undoubtedly help scientists with their academic papers by summarizing research and helping to improve writing. However, one downside is that it has led to a wave of poorly written submissions and reviews, according to a new study published in Organization Science.

Proton beam timing tool could check radiotherapy energy before nearly every treatment‎

Proton beams are not only used in sophisticated nuclear physics experiments. Today, they are becoming increasingly popular in radiotherapy, where they are an irreplaceable tool for destroying cancer cells. Doctors and physicists can enhance their precision thanks to two solutions developed at the Cyclotron Center Bronowice of the Institute of Nuclear Physics, Polish Academy of Sciences.
