Thinking of drinking and driving? What if your car won't let you?

Researchers estimate that installing alcohol ignition interlock devices in all new cars could prevent up to 85% of crash deaths attributable to alcohol-involved motor vehicle crashes. This would save over 59,000 lives and prevent 1.25 million non-fatal injuries. The estimated cost savings would be $343 billion over 15 years.

Better season-long nutrient supply in soybean a 'low-hanging fruit' to improve upon

A recent study by the University of Illinois has identified specific nutritional needs for soybeans to improve yield and seasonal nutrient supply. The researchers found that nutrients such as phosphate, potassium, nitrogen, sulfur, and copper are critical for high-yielding success.

Kidney cancer detected early with urine test

Researchers developed a non-invasive method to screen for kidney cancer by measuring protein biomarkers in urine, achieving over 95% accuracy. The findings suggest the potential for an easy-to-use screening test, similar to mammograms or colonoscopies, to identify patients with kidney cancer at early stages.

New strategy to protect healthy gut microbes from antibiotics

A study published in Cell Reports reveals a potential strategy for promoting the right balance of gut microbes in antibiotic-treated mice by manipulating the autoinducer-2 (AI-2) chemical signal. The researchers found that high levels of AI-2 increased the expansion of Firmicutes phylum, leading to a healthy state of the gut microbiota.

Spreading the seeds of big data

MSU researchers are using big data analytics to help farmers adapt to climate variability, reducing nitrous oxide emissions and algal blooms. The project aims to integrate crop models with satellite imagery and UAVs to promote water-, nutrient- and climate-smart technologies.

Spot treatment

Acne sufferers may benefit from a new therapy that reduces breakout frequency and intensity using ultrasound, gold-covered particles, and lasers. The treatment works by deactivating sebaceous glands, reducing sebum production and preventing bacterial growth.

The cost of dominance

A series of University of Utah studies found that hostile-dominant personality styles are associated with increased vulnerability to cardiovascular disease, including higher blood pressure and severe atherosclerosis. In contrast, warm-dominant styles are linked to lower blood pressure and more support in marriages.

NIH-funded researchers find off-patent antibiotics effectively combat MRSA skin infections

Researchers have found that clindamycin and TMP-SMX are equally effective in treating uncomplicated skin infections caused by community-associated MRSA. The study's findings suggest that these off-patent antibiotics can be used successfully to combat MRSA skin infections acquired outside of hospitals.
