A team of physicists has devised a general theorem to explain the phenomenon of allometric quarter-power scaling, which describes how biological processes vary in predictable ways depending on an organism's mass. The researchers found that efficient transportation networks, including those in plants and animals, follow this scaling law.
Researchers at Pacific Northwest National Laboratory developed a prototype engineering tool to aid in verifying an aircraft's stealth characteristics. The Holographic 3-Dimensional Radar Camera can be deployed worldwide and provides images of radar reflections to assess the condition of radar-absorbing material.
Scientists discover cytosolic catalase enzyme protects cells from oxidative damage in long-lived worms, offering insight into aging process and potential therapy for nervous system diseases. The study suggests that increasing cellular health through antioxidant measures could extend lifespan, rather than relying on genetic regulation.
Researchers at UT Southwestern Medical Center have developed a novel method to turn off genes involved in telomerase activation, which enables continuous cell division in cancer cells. The study used peptide nucleic acid (PNA) molecules to block telomerase activity, showing significant promise for developing new cancer drugs.
Rice University researchers develop fullerenes that can be cleared from the body and specifically targeted to bone tissue. The findings have promise for medical applications such as nuclear medicine and drug delivery.
Six university teams will showcase their innovative food products, including Sweet Spots, Jammm Singles, and Tater Stuffs. The teams will compete for top honors based on product originality, feasibility, innovativeness, and market potential.
NYU chemist Robert Shapiro challenges existing assumptions about life's universality with a new theory that simple cellular life may arise from organic chemistry and self-organizing systems. He also advocates for continued search for extraterrestrial life in nearby worlds like Mars, Europa, and Titan.
Johns Hopkins engineering undergraduates develop a restraining bar system that could reduce school bus injuries by protecting children without seat belts. The device features a pivoting bar with a manual-release lever, designed to keep children secure during head-on collisions or rollover accidents.
Representatives from IFT, FDA, and industry experts will discuss cooking and food storage time and temperature specifications in restaurants and retail food operations. The forum aims to enhance food safety and quality worldwide through information exchange and knowledge sharing among members.
The new microscope employs a scanning metal tip and infrared wave absorption to identify chemical composition on a nanoscale. The technique has potential for high-resolution imaging with 100 nm or better resolution, expanding its applications in electronics, materials, and biology.
A study by NIH/NINDS scientists mapped a specific brain region responsible for human multitasking behavior, identifying the fronto-polar prefrontal cortex (FPPC) as the key area. This finding suggests that humans have a unique ability to switch between tasks while maintaining working memory and attentional focus.
Researchers discovered three-dimensional record of locomotor behavior in Triassic-period dinosaurs preserved in fossil footprints. The tracks showed that both theropod dinosaurs and birds moved their feet in a similar way, with the toes collapsing together below the surface as the entire foot emerged.
Kodak and Intel are teaming up to produce a device that lets normal stills cameras take digital pictures. The new technology uses microchips that can be built into film cameras, allowing images to be transferred to CD-ROM for permanent storage.
Researchers found that folic acid fortification in grains increased plasma folate levels and reduced total homocysteine concentrations. This study provides important information on the impact of consuming specific amounts of folate on blood homocysteine levels, which may have implications for reducing heart disease risk.
