Optical Atomic Clock: A Long Look At The Captured Atoms
Optical Atomic Clock: A Long Look At The Captured Atoms
Optical clocks might become the atomic clocks of the future. Their "pendulum", i.e. the regular oscillation process which each clock needs, is an oscillation in the range of the visible light. As its frequency is higher than that of the microwave oscillations of the cesium atomic clocks, physicists expect another increase in the accuracy, stability and reliability.
Knee Brace Generates Electricity From Walking
A new energy-capturing knee brace can generate enough electricity from walking to operate a portable GPS locator, a cell phone, a motorized prosthetic joint or an implanted neurotransmitter. The researcher, who called the device "a cocktail-napkin idea," says knee joints are uniquely suited for this endeavor.
Impaired Fat-burning Gene Worsens Diabetes, Study Shows
Researchers have discovered new cellular mechanisms that lead to in insulin resistance in people with diabetes. The research team identified a 'fat-burning' gene, the products of which are required to maintain the cells insulin sensitivity. They also discovered that this gene is reduced in muscle tissue from people with high blood sugar and type 2-diabetes.
Worried About Family Or Friends Falling? New Guideline Identifies Those Most At Risk
A new guideline developed by the American Academy of Neurology finds certain neurology patients are at a high risk of accidental falls and should be regularly screened to help prevent the high number of fall-related injuries and deaths in the United States each year.
Moderate Prenatal Exposure To Alcohol And Stress In Monkeys Can Cause Touch Sensitivity
A new study that exposed monkeys to moderate levels of alcohol and stress in pregnancy found increased sensitivity to touch in the monkeys' babies. Using a brain neuro-imaging technique, the researchers found that sensitivities to touch were related to changes in the brain chemical dopamine one area of the brain. Since sensitivity to touch in human children can lead to behavioral and emotional problems, this research has important implications for preventing childhood disorders.
