Lucy’s primary goal is to survey the never-before-visited Jupiter Trojan asteroids. The excellent performance of that system at Dinkinesh allowed the team to capture multiple perspectives on the system, which enabled the team to better understand the asteroids’ shapes and make this unexpected discovery. Scientists use climate and weather models to understand how our global climate has changed over the past century, how it might change in the future and what influences those changes. Those models depend on meteorological records from around the globe and are only as accurate as the data that anchor them. Social science is the branch of science devoted to the study of societies and the relationships among individuals within those societies.

The belief that science has had a positive effect on society correlated strongly with education. Of those with a high school education or less, less than half said that science has had a mostly positive effect on society. That rose to 72 percent among those who completed college and 79 percent for those with a graduate degree. From 2016 to 2021, the portion of US residents who felt science had a mostly positive effect on society hovered within three points of 70 percent. Eight percent now feel that science has had a mostly negative impact, up from a low of just 3 percent in January 2019. The drop is most pronounced for self-identified Republicans and those without a college education.

The 19th century saw breakthroughs occur after observing networks developed across several countries. After the development of the computer in the latter half of the 20th century, breakthroughs in weather forecasting were achieved.

Only when the team downlinked additional images, captured in the minutes around the encounter, was the true nature of this object revealed. Observations over landcan be collected by weather stations, but the effort is more complicated at sea. In the early 20th century, before the advent of satellites, most maritime weather data were gathered voluntarily by sailors aboard commercial trading ships. Before this project, the observations “had never been seen by anybody else except the people who wrote them,” saysPraveen Teleti, lead researcher on the project and a climate modeler at the University of Reading in the United Kingdom.

Another type of light microscopy is fluorescence microscopy, which is used to image samples that fluoresce . Light of one wavelength is used to excite the fluorescent molecules, and the light of a different wavelength that they emit is collected and used to form a picture. In most cases, the part of a cell or tissue that we want to look at isn’t naturally fluorescent, and instead must be labeled with a fluorescent dye or tag before it goes on the microscope. A real-world test of Nader’s theory of memory reconsolidation is taking place a few miles from his Montreal office, at the Douglas Mental Health University Institute. Alain Brunet, a psychologist, is running a clinical trial involving people with post-traumatic stress disorder .

Jupiter has a tendency to take comets that come too close and fling them out of the solar system. The few that do end up on Earth-crossing orbits don’t stay there for long. When the solar system formed about 4.6 billion years ago, shards of calcium- and aluminum-rich minerals stuck together, building ever-larger pebbles and boulders that smashed together and assembled the rocky planets, including Earth. Electron microscopes are typically produced by various manufacturers around the world.

Gwynne, now 72, is a bit chagrinned that from a long career of distinguished science and technology reporting, he is most remembered for this one story. It is commonly said that scientists should have a professional distance from what they study. To the extent that we can remove our biases and learn from multiple perspectives, we will understand our world better. Productivity and equity are probably the most often cited reasons to attend to diversity in science.

Both of these comets are part of a community known as Jupiter family comets. They originated in the Kuiper belt, the ring of icy debris beyond Neptune where Pluto lives. The gravity of first Neptune and then Jupiter gradually nudged these comets into relatively short orbits that bring them closer to the sun. All previous D/H measurements were of comets that hail from the far more distant Oort cloud, a shell of ice fragments that envelops the solar system.

Heat from the young sun vaporized any ice that dared to come near the inner planets. Earth’s relatively feeble gravity couldn’t grab on to the water vapor, or any other gas for that matter. Water regulates the climate, shapes and reshapes the landscape and is essential to life.
