7 Months After Infection, SARS-CoV-2 Antibody Levels Remain Stable or Even Increase
The levels of antibodies against the SARS-CoV-2 Spike protein remain stable, or even increase, seven months after infection, according to a study. The results also support the idea that pre-existing antibodies against common cold coronaviruses could protect against COVID-19.

Getting a Real Snapshot of Algal Bloom Toxins
Remote-sensing technology produces detailed images of the size and density of the harmful algal bloom (HAB) in Lake Erie’s western basin each year, but in order to determine the bloom’s toxicity, the water must be tested. Researchers have provided the most accurate estimates to date of where and how much of the liver toxin microcystin might be present during a seasonal bloom.

Exercise Makes Change Easier in the Depressed Brain
The dual beneficial effect of physical activity in depression is confirmed by a new study: physical activity not only reduces depressive symptoms, but also increases the brain’s ability to change, which is necessary for adaptation and learning processes.

Tiny Protein "Squeezes" Cells Like Balloon Animals
According to scientists, a protein that causes a cell’s skeleton to bend, allowing it to twist the cell into different shapes, could be key to how cells divide. Their results point to new ways to modify and engineer cells, as well as a better understanding of how they replicate.

Getting to Grips With the Marine Ecosystem From the Bottom-Up
Phytoplankton are the foundation of ocean ecosystems: like rainforests, they consume carbon from the atmosphere, form the basis of the marine food web and have a decisive influence on fish abundance and global climate. Scientists have now provided new insights into the complex biogeochemical processes at the base of the marine ecosystem.

New Mitochondrial Recycling Pathway Uncovered
Scientists have long known that living cells are master recyclers, constantly breaking down old parts and building them back up into new molecular machines. Now, researchers at Gladstone Institutes have taken a closer look at the life cycle of mitochondria inside brain cells and how they might be recycled.
