A Giant Seismic Wave Bounced Off Earth's Core And May Have Shifted Japan - ScienceAlert

Could changing your diet really turn back your body's clock? Not the wrinkles on your face or the gray in your hair. The clock in question is hidden in signals carried by your blood, metabolism, and cardiovascular system. In a new study, some older adults ate differently for just four weeks – and estimates of their biological age shifted several years younger. Even more surprising, the strongest change appeared in a group eating more carbohydrates and less fat, challenging the familiar idea that carbs must always be cut. So did these people really become younger in a month? Or did the clock measure something more fleeting? The study, published in Aging Cell, offers an intriguing but cautious answer. Researchers at the University of Sydney analyzed data from 104 adults aged 65 to 75 who participated in the Nutrition for Healthy Living trial. Every meal they ate for four weeks was prepared and delivered by the researchers. Participants did not count calories and could eat as much as they wanted from the supplied menus. They were randomly assigned to four groups, meaning they did not choose which diet to follow.

AbstractAccording to the third theorem of similarity, a layered physical model was established using two types of materials with different shear stiffnesses. This model was used to represent the prototype in shaking table tests, and the influences of the burial depth and thickness of the hard interlayer on the amplification factor and on the characteristic parameters of the response spectrum were analysed and studied. The study revealed the following: (1) The influence trends of the burial depth and thickness of the hard interlayer on the amplification factor and on the characteristic period of the response spectrum obtained from the shaking table tests were found to be consistent with those obtained from a one-dimensional equivalent linearization calculation. This comparison serves as a verification of the experimental results rather than as an independent conclusion.
