A group of Duke University engineering students designed and built a custom-made goalie slider for Daniel Delimata, a cerebral palsy patient who was unable to participate in street hockey games. The slider allows him to move more efficiently and effectively, improving his coordination, balance, and overall playing experience.
Researchers propose optimality theory to explain how infants quickly learn complex languages. The idea suggests that a basic understanding of language is already present in the brain, requiring only fine-tuning mechanisms to acquire specific grammar rules.
Astronomers worldwide are gathering data from comet Hale-Bopp with a festival of observations, revealing secrets about comets' composition and behavior. The raw material will construct the most intricate portrait of a comet to date, providing insights into the early solar system.
Cancerous cells produce high amounts of free-radicals that promote uncontrolled cell growth; antioxidants and protein inhibitors can suppress this process, slowing down runaway cell division.
The new map reveals hot spots for genes and a large region where DNA remains intact across generations. It also identifies variations in chemical composition along the chromosome, shedding light on X's genetic code
A new study published in Science by a team led by University of Wisconsin-Madison geochemist John W. Valley reveals low-temperature origin for the carbonate globules found within the meteorite ALH84001, lending powerful support to the notion that features of the meteorite may have been formed by living organisms.
Researchers visualize calcium stored deep within intact muscle and brain cells, discovering tiny, discrete compartments that can be opened or closed by drugs or natural chemicals. This finding could lead to a better understanding of physiological mechanisms underlying high blood pressure, heart failure, stroke, and aging.
