Using magnetic tweezers, scientists can move DNA molecules in three dimensions, opening up possibilities for non-invasive surgical tools and targeted medicine delivery. The device works by using electromagnetic fields to manipulate iron oxide-coated beads attached to the DNA molecule, allowing precise control over movement.
Researchers at Oak Ridge National Laboratory developed a miniature video camera that can transmit to a site up to 100 feet away, such as a police car. The camera features a disguised lens that makes it unobtrusive, and its design enables secure surveillance and protection for law enforcement.
Researchers at Columbia University have developed a 360-degree videocamera called Omnicam, which can capture hemispheric views and display them in linear perspective on screens. The technology has various applications, including surveillance, teleconferencing, and robotic vision.
Researchers at Resources for the Future (RFF) and Stanford University are investigating the environmental implications of three alternative tax plans under discussion in Congress. The flat tax, national sales tax, and unlimited savings account (USA) tax plans could have varying effects on economic growth and environmental quality.
A study of over 2,500 children born between 1960-1965 found that most have achieved success in education, lifestyle, health, and financial independence by their thirties. Living with both parents, avoiding poverty, good behavior, and participation in school activities were key predictors of successful outcomes.
Researchers at Johns Hopkins School of Public Health found that drawstrings on clothing can cause strangulation or dragging injuries, resulting in eight child fatalities between 1985-1994. The study recommends eliminating or modifying drawstrings to prevent these accidents.
