A new laser therapy, transmyocardial revascularization (TMR), has been found to be effective in reducing chest pain in patients with coronary artery disease. The procedure creates new blood-carrying channels in the heart muscle, improving oxygen supply and reducing symptoms.
A recent meteorite study has provided insights into Mars' formation by analyzing volatile elements in Martian meteorites. The findings indicate that the planet experienced at least two fractionation events, which allowed all elements to remain and record past events.
Scientists are simulating a small-scale environment with increased carbon dioxide levels to study the impact on forests and ecosystems. They will monitor tree growth, soil changes, and other biological interactions in the controlled area.
Researchers from Stanford University and IBM's Almaden Research Center successfully measured forces of infinitesimal magnitude for the first time using a new method called magnetic resonance force microscopy. The technique enables the detection of atto-newton forces, which are one billionth of a billionth of a newton.
Researchers at ORNL have developed ceramic valves that offer longer life and better durability for heavy-equipment engines. The valves were tested in a mine haul truck engine and accumulated over 2,000 hours without failing.
A recent Henry Ford study reveals that denial of anger is a stronger predictor for death and cardiac incidents than traditional risk factors. Patients tend to minimize their emotional well-being, making it difficult for physicians to accurately assess their risk factors.
Researchers have developed a theory to explain the sudden change of rare earth mirror materials into transparent windows when exposed to hydrogen. This phenomenon has potential applications in smart windows for energy savings.
Law enforcement teams can practice responding to hostage situations using a virtual reality simulation called VRaptor. The simulation allows participants to determine who are the hostages and save them, take prisoner those kidnappers who surrender, and shoot those who fire weapons.
Researchers found that bulimics exhibit a range of physiological and psychological problems, including abnormal blood pressure, poor response to stress, and low self-esteem. The study also revealed that bulimics are more likely to experience cardiovascular problems and major depression.
