New imaging method illuminates oxygen's journey in the brain

A new bioluminescence imaging technique has created highly detailed, and visually striking, images of the movement of oxygen in the brains of mice. The method, which can be easily replicated by other labs, will enable researchers to more precisely study forms of hypoxia in the brain, such as the denial of oxygen to the brain that occurs during a stroke or heart attack. The new research tool is already providing insight into why a sedentary lifestyle may increase risk for diseases like Alzheimer's.

Cell division quality control 'stopwatch' uncovered

Biologists have uncovered a quality control timing mechanism tied to cell division. The 'stopwatch' function keeps track of mitosis and acts as a protective measure when the process takes too long, preventing the formation of cancerous cells.

Climate change policies lose popularity when combined with pausing regulations or social justice

Legislators love bundling things together. It lets them accomplish more with less hassle and attempt to make legislation more appealing to a broader group. But a new study suggests that this can sometimes backfire. The authors found that pairing climate policies with other policies does not necessarily increase their popular appeal, and can actually reduce public support.

Mechanism found to determine which memories last

Neuroscientists have established in recent decades the idea that some of each day's experiences are converted by the brain into permanent memories during sleep the same night. Now, a new study proposes a mechanism that determines which memories are tagged as important enough to linger in the brain until sleep makes them permanent.
