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.

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.

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.

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.

More than one-third of infant caregivers surveyed reported serving at least one non-recommended milk type to their infant in the past month, according to a new study.

A group of medications used to treat tapeworm has inspired a compound that shows effectiveness against COVID-19 in laboratory studies.

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.

Pancreatic cancer is one of the deadliest forms of cancer, with fewer than 10% of patients surviving for five years after diagnosis. Pancreatic tumors often become resistant to chemotherapies. Researchers have now developed an immunotherapy strategy and shown that it can eliminate pancreatic tumors in mice.

Engineers at MIT and Harvard University have designed a small tabletop device that can detect SARS-CoV-2 from a saliva sample in about an hour. In a new study, they showed that the diagnostic is just as accurate as the PCR tests now used.

Researchers have devised a new method to prevent bacterial infections that can occur from surgical implants, by covering a graphene-based material with bactericidal molecules.
