School focus on grades and test scores linked to violence against teachers

School focus on grades and test scores linked to violence against teachers

Credit: Unsplash/CC0 Public Domain Violence against teachers is likely to be higher in schools that focus on grades and test scores than in schools that emphasize student learning, a new study has found. Researchers surveyed over 9,000 U.S. teachers shortly before and during the height of the COVID-19 pandemic about their perception of the instructional … Read more

Scientists can tell where a mouse is looking and located based on its neural activity

Scientists can tell where a mouse is looking and located based on its neural activity

Researchers have paired a deep learning model with experimental data to “decode” mouse neural activity. Using the method, they can accurately determine where a mouse is located within an open environment and which direction it is facing just by looking at its neural firing patterns. Being able to decode neural activity could provide insight into … Read more

Three years later, search for life on Mars continues

Scientists can tell where a mouse is looking and located based on its neural activity

In the three years since NASA’s Perseverance rover touched down on Mars, the NASA science team has made the daily task of investigating the red planet seem almost mundane. The rover and its helicopter sidekick Ingenuity have captured stunning images of Mars and collected 23 unique rock core samples along 17 miles of an ancient … Read more
