The Virtual Mass Spectrometry Laboratory (VMSL) is an interactive educational tool that allows students to learn how to solve real problems in various scientific disciplines. The system connects students to data files from four mass spectrometers, enabling them to analyze compounds and proteins using different instruments.
A new study reports the results of several studies on determining the optimum materials for use as a proton exchange membrane in methanol-based fuel cells. The researchers believe that methanol-based fuel cells could be developed before hydrogen-based fuel cells, providing a convenient and accessible alternative for powering devices.
Researchers investigate how changes in polymer environment and glass transition temperature impact stability in medical implants. Hydration can affect polymer degradability and structural stability, highlighting the need for tailored material properties.
Researchers have combined an antibody with an antioxidant enzyme to protect transplanted lungs from oxidative stress, improving lung-graft survivability and storage time. The anti-PECAM/catalase hybrid construct strengthened antioxidant defenses and reduced free-radical damage in animal models.
Researchers have developed a new method to measure the attraction between particles and surfaces using an atomic force microscope. This technique allows for the simulation of various environmental conditions and the quantification of sticking efficiencies, which can improve contaminant removal methods.
Researchers at Michigan State University have identified a gene responsible for Smith-Magenis Syndrome (SMS), a rare genetic disorder. The discovery suggests that primarily one gene contributes to the phenotype, rather than multiple genes as previously thought.
Scientists at Rensselaer Polytechnic Institute create computer models of proteins to integrate them into dry substances like plastic. This development could lead to new applications in the security and medical industries, such as ultra-hygienic surfaces and chemical sensors.
Virginia Tech researchers discovered that tert-butoxyl radicals are more reactive than initially thought, making them a poor model for studying oxygen-free radicals in biological systems. This finding challenges previous assumptions about the behavior of these radical species.
Researchers have developed contact lenses that can dispense prescription drugs directly to the eye, reducing the risk of side effects associated with traditional eye drops. The new technology uses nanoparticles to encapsulate drugs in a matrix, allowing for controlled release over an extended period.
A new spice-like substance, made from freeze-dried egg yolk, shows promise in preventing foodborne illnesses. The antibody-based compound can remain active for up to two hours after ingestion, providing precious time to seek medical attention.
Cornell researchers have developed a highly efficient chemical route to produce the biodegradable polymer poly(beta-hydroxybutyrate), which has potential applications in various industries. The discovery is a significant breakthrough in creating sustainable materials, with the potential to replace traditional plastics.
Researchers have developed a novel fabrication technique to create interconnected cylindrical channels, enabling efficient mixing in microfluidic devices. The microvascular networks can also serve as a circulatory system for continuous transport of repair chemicals in self-healing materials.
The Illinois team developed a new technique to create three-dimensional microchannel networks that improve fluid mixing efficiency compared to traditional two-dimensional channels. The technology also enables the creation of self-healing materials with integrated 'circulatory systems' for transporting repair chemicals.
Researchers studied adults whose cognitive abilities were first tested at 11 and found that brain white-matter abnormalities made a significant contribution to general cognitive ability differences in old age. Early IQ scores also played a role, but independently of each other.
