WASHINGTON — Talking with your hands can trigger mental images that help solve complex problems relating to spatial visualization, an important skill for both students and professionals, according to new research published by the American Psyc…
Some people always know which way is north and how to get out of a building. Others can live in an apartment for years without knowing which side faces the street. Differences among people that include spatial skills, experience, and preferred strat…
COLUMBIA, Mo. — Diagnostic ultrasounds are the most widely used medical tests in the world. Though the technology is more than 50 years old, scientists continue to discover new uses for it, ranging from more targeted cancer treatments to lip…
Scientists have for the first time estimated the physical footprint of human activities on the deep seafloor of the North East Atlantic. The findings published in the journal PLoS ONE reveal that the area disturbed by bottom trawling commercial …
In “The Sign of the Four” Sherlock Holmes tells Watson he has written a monograph on 140 forms of cigar-, cigarette-, and pipe-tobacco, “with colored plates illustrating the difference in the ash.” He finds the ash invaluable for the identificat…
Studying mice, scientists have successfully prevented a molecular event in brain cells that they’ve found is required for storing spatial memories. Unlike regular mice, the engineered rodents quickly forgot where to find a resting place in a pool of water, the researchers report in the March 7 issue of the journal Cell. The experiments are believed to be the first to prove that subtly altering the chemistry of a certain protein can profoundly affect a brain cell’s ability to respond to external stimulation, a process called neuronal plasticity, long thought to underlie learning and memory.
