UT Dallas study sheds light on how infants understand speech

A new UT Dallas study explores how infants process degraded speech with cochlear implants, revealing they need more complete speech information to maximize communication outcomes. Infants can distinguish between familiar and new sounds, but require less distortion and more frequency information than older children and adults.

Racing the clock to help young patients with old hearts

A study by University of Maryland researchers has identified a toxic protein that damages muscle cells inside the arteries of children with progeria, a rare genetic disorder. The discovery may help explain how cardiovascular disease develops in people aging normally and could lead to new treatments for the condition.

Your high school GPA could affect your income

Researchers at the University of Miami found that a one-point increase in high school GPA raises annual earnings by around 12% for men and 14% for women. The study also shows that African-Americans with high GPAs are more likely to graduate from college than their white counterparts.

Chemists challenge conventional understanding of how photocatalysis works

A team of chemists at UC Riverside proposes a new model explaining the promoting effect in photocatalysis, suggesting that excited electrons promote hydrogen reduction on the semiconductor surface rather than transferring to metals. This radical approach could lead to the development of more economical and efficient photocatalysts.

Scientists develop new approach for sampling gut bacteria

Researchers have developed a protocol for collecting saliva and stool samples for genomic and transcriptomic analyses, eliminating the need for specialized personnel and facilities. This method provides critical insight into the genetic makeup of the microbiome and its association with diseases such as celiac disease, oral cancer, and ...

Why you need olive oil on your salad

A study by King's College London found that combining unsaturated fats with vegetables rich in nitrites and nitrates can protect against hypertension. The Mediterranean diet, which includes olive oil and nuts, was shown to inhibit the enzyme responsible for blood pressure regulation.

Illuminating neuron activity in 3-D

Scientists have developed a new imaging system that reveals neural activity throughout the brains of living animals in 3-D. The technique allows for simultaneous imaging of every neuron in the worm Caenorhabditis elegans and the entire brain of a zebrafish larva, providing a more complete picture of nervous system activity.

How does snow affect the amount of water in rivers?

New research shows that the amount of water flowing through rivers in snow-affected areas depends on how much precipitation falls as snowfall. In a warming climate, reduced snowfall leads to decreased river discharge. The study highlights the importance of streamflow for society, including ecosystem stability and hydropower.
