Series of reactions reveals how complex carbon chemistry can begin in frigid space‎

Before there was Earth, there was chemistry. In the unimaginable cold, dark clouds where stars and planets are born, carbon molecules assemble into more complex forms—starting a chemical journey that could eventually deliver some of life's basic ingredients to young planets. There's only one problem: These molecules need heat to form. At least that's what scientists have long believed. But new research from FIU chemist Alexander Mebel reveals such chemistry can actually happen at temperatures nearing absolute zero, which is -460°F (-273°C).

Novel solvent recipe boosts efficiency of organic solar cells‎

In a study recently published in the Chemical Engineering Journal, a research team from National Taiwan University and international collaborators have developed a straightforward solvent-mixing strategy to significantly boost the performance of next-generation all-polymer organic solar cells. By adding a small fraction of a cosolvent during fabrication, the team successfully resolved a long-standing challenge in controlling film quality, opening new possibilities for commercializing flexible, efficient and sustainable clean energy technology.

Car owners beware! Lessons from the 'Kia Boys' crime spree‎

If you live in Los Angeles and own a Hyundai Sonata, Kia Optima or one of 18 other models from these vehicle lines, UCLA anthropologist Jeffrey Brantingham has some advice: Get a steering wheel locking device, take advantage of manufacturer recalls or trade your car in for one with an engine immobilizer.

Social isolation in Australia has nearly doubled over two decades‎

Australians are becoming increasingly lonely and socially isolated, according to new University of Sydney research that found rates of social isolation nearly doubled over the past 23 years. Loneliness rates also increased over time, though more gradually than social isolation, with the sharpest impacts observed among vulnerable populations.

Mosquito 'toilet' detects West Nile and first Hedwig-like virus found in the Americas‎

When public health researchers want to know whether diseases such as COVID-19 or polio are circulating in a community, they can look for genetic evidence in wastewater.

Speedy electrons for brilliant laser light: Research paves the way for compact, inexpensive free-electron lasers‎

Extremely short, intense light flashes are in high demand to investigate atoms, molecules and new materials. Free-electron lasers (FELs) produce these flashes. But around the world, beam time available at large-scale user facilities is in short supply, and waiting times are long.

School segregation endures in Baltimore region, report finds‎

Although public schools in Baltimore City are predominantly Black, the district is doing a better job of reducing segregation among its student body than suburban systems that are able to draw from more diverse populations, according to a new report from Johns Hopkins University.
