Researchers analyzed 19 samples of honey from 14 different floral sources and found that dark buckwheat honey packs 20 times the antioxidant punch as California sage honey. Darker honey has less water and more antioxidants than light-colored honey, making it a potential supplemental source for antioxidants.
A new study found that the biggest factor in student cheating is the instructor, with tenured or tenure-track faculty reducing cheating. Professors can reduce cheating by offering multiple exam versions, giving verbal warnings, and using additional proctors, making students 25-13-11 percent less likely to cheat.
A team of researchers found evidence of epitaxial processes that formed magnetite crystals in the ALH84001 meteorite, contradicting claims of nanofossils. The study suggests that the crystals were formed at temperatures too high for biological organisms to exist.
Researchers suggest that traumatic events in preschool years can significantly affect brain development and function. Extensive corrective experiences have been shown to help repair damaged neural connections over time.
Using high-intensity ultrasound, researchers discovered a dramatically improved catalyst for removing sulfur-containing compounds from gasoline and other fossil fuels. The new form of molybdenum disulfide is 10 times more active than the standard industrial catalyst.
Researchers developed a tamper-proof watermarking process that protects both owners and legitimate customers of multimedia data. The system combines encryption with part of the original image to create an invisible watermark.
Two Idaho National Engineering and Environmental Laboratory-developed technologies have been recognized internationally for their potential to improve the power industry. The Electro-Optic High Voltage Sensor provides safer and more cost-effective ways to measure high voltages. Rapid Solidification Process Tooling Technology reduces pr...
The Harbor Branch Oceanographic Institution is building a $1.5 million ocean sciences museum with a self-guided format, featuring interactive exhibits and displays on marine research, education, engineering, and ocean operations. The museum will open in late 1998.
The new microfluidic-NMR system enables high-performance capillary electrophoresis separations and simultaneous NMR spectroscopy, facilitating the development of desktop spectrometers. The technology has significant applications in drug discovery and combinatorial chemistry.
Archaeologist Stanley Ambrose's findings from the Enkapune Ya Muto rock shelter in Kenya suggest that modern human behavior emerged around 40,000 years ago. The discovery of stone tools and ostrich eggshell beads indicate an early form of social solidarity and adaptive technology.
Researchers suggest that anti-smoking programs should focus on countering the influence of parent smoking, rather than just peer pressure. Early interventions may help modify risk factors such as low behavioral self-control and parental monitoring.
Researchers found a link between rainfall and nitrate leaching, with increased rainfall leading to higher nitrate levels in tile flow. The study recommends applying nitrogen fertilizer in the spring to prevent excessive nitrate loss.
Researchers have demonstrated an instance of a thin ion layer being pushed downward to create a neutral sodium layer. Contrary to predictions, the formation of this layer was not significantly affected by intense auroral ionization, revealing new insights into the physics and chemistry of the upper atmosphere.
