Researchers at Purdue University have successfully modified yeast to ferment both glucose and xylose from plant matter, producing more ethanol from the same amount of material. This breakthrough could make ethanol production cheaper and more sustainable.
A scientific team's findings suggest that tsunamis may pose a significant threat to the Pacific Rim and other coastline regions due to the instability of submarine structures. The team believes that earthquakes of magnitude 7.0 or greater can trigger massive underwater landslides, resulting in devastating tsunamis.
A new environmental monitoring system, E-SMART, uses integrated optic chemical sensors to detect contaminants in soil, groundwater, and air. The system reduces health and safety risks, saves time and cost by operating in situ, and enables real-time assessments of environmental impact.
Mass extinctions may not be fundamentally different from local catastrophes in their impact on global diversity. According to University of Cincinnati geologist Arnold Miller, regional and local bursts of diversification occur at different times around the world, contributing to a misleading picture of diversification trends.
The significance of defects in semiconductors cannot be overstated, as they determine many crystal qualities and enable the creation of useful variability. The controlled substitution of host atoms by foreign atoms is a key idea in semiconductor materials engineering.
Researchers used fMRI to capture brain activity during verbal tasks, revealing specific structures involved in memory formation. The study found that increased activity in the left frontal and temporal lobes can predict whether participants will remember a word seen in the scanner.
A recent study found that males from father-absent households face a significantly higher risk of incarceration, with odds almost three times as high as those from intact families. The presence of live-in grandparents in these households can help mitigate this risk.
Four Pennsylvania science teachers participated in a research expedition to study hydrothermal vents and active volcanoes on the ocean floor. The teachers worked with international scientists to understand how communities of animals live on these structures and developed new lesson plans for their students.
Researchers discovered a gene segment that can 'jump' into foreign DNA, enabling vertebrates to create millions of different antibodies. This ability is crucial for the adaptive immune system, which relies on two lines of defense to detect and destroy invaders.
The website provides a comprehensive educational program on genetics, genetic testing, diagnosis, counseling, and cancer risk assessment. It features three levels of education for different audiences and includes case scenarios, problem sets, and moderated discussion groups.
Researchers at Duke University Medical Center have discovered a molecular motor mechanism that divides genes during cell reproduction. The discovery provides clues to infertility and birth defects, such as Down syndrome, by understanding how chromosomes are separated during cell division.
