High school students tend to get more motivated over time

Science Daily - 01/03/2021
Parents may fear that if their high school student isn't motivated to do well in classes, there's nothing that will change that. But a new study that followed more than 1,600 students over two years found that students' academic motivation often did change - and usually for the better. Results showed that increasing students' sense of 'belongingness' in school was one key way of increasing academic motivation.

Astronomers accurately measure the temperature of red supergiant stars

Science Daily - 28/02/2021
Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers develop an accurate method to determine the surface temperatures of red supergiants.

Imaging space debris in high resolution

Science Daily - 27/02/2021
Researchers have introduced a new method for taking high-resolution images of fast-moving and rotating objects in space, such as satellites or debris in low Earth orbit. They created an imaging process that first utilizes a novel algorithm to estimate the speed and angle at which an object in space is rotating, then applies those estimates to develop a high-resolution picture of the target.

When using pyrite to understand Earth's ocean and atmosphere: Think local, not global

Science Daily - 27/02/2021
Scientists have long used information from sediments at the bottom of the ocean to reconstruct the conditions in oceans of the past. But a study raises concerns about the common use of pyrite sulfur isotopes to reconstruct Earth's evolving oxidation state. These signals aren't the global fingerprint of oxygen in the atmosphere, according to new research from Washington University in St. Louis.
