To get to Earth, it traveled for more than 12.8 billion years. The glow…

Because you’re a very responsible person who doesn’t text and drive, when you roll over a bridge your smartphone is stuck to the dash, where it is perhaps giving you directions while streaming a WIRED podcast. But in the background, your device is also gathering reams of accelerometer data. One day, this could help diagnose problems with the very bridge you’re speeding across.Every bridge has its own “modal frequency,” or the way that vibrations propagate through it—then subsequently into your car and phone. (Tall…

Overview of the variation in color for charred (A) and combusted (B) bone exposed to pH 3 and pH 12 conditions. Credit: Scientific Reports (2022). DOI: 10.1038/s41598-022-21622-5 The use of fire can tell us a lot about human evolution. Archaeologist Femke Reidsma has developed a more accurate technique to identify how our ancestors used fire, implying that existing archaeological studies may need to be revised. Reidsma's study…

Credit: Pixabay/CC0 Public Domain A student's self-perception of what they are good at and how good they are at different types of tasks predicts their future scholastic performance and choices. For example, students who perceive themselves as good at math are more likely to engage in math class, earn good grades in math, and enroll in advanced math classes as they progress through their educational careers, compared to…

Most albatrosses mate for life but shy males who avoid confrontation are more likely to get dumped, researchers said Wednesday, adding it was the first time personality had been shown to predict divorce in a wild animal.Wandering albatrosses, which traverse the Southern Hemisphere and have the largest wingspan of any bird at more than three meters (10 feet), are among the most monogamous animals.They can live for more than 50 years, and while they spend much of that time on the wing, they meet up every two years with the…

After conducting successful Mars missions and sending rovers to explore the Red Planet, scientists are investigating the possibility of a human landing on Mars. A team of space medicine experts has proposed a mathematical model that could be used to predict if an astronaut can safely reach Mars and carry out missions after stepping on the planet's surface. The experts tried to examine if the human body can tolerate the gravitational force of Mars without fainting or experiencing a medical emergency. They have simulated…
