Telecoupling science shows China's forest sustainability packs global impact

A Michigan State University scholar proposes the telecoupling framework to understand how China's domestic decisions influence other countries and vice versa. The research shows that China's efforts to sustain forests can have substantial global impacts, including reappearing deforestation in countries that sell lumber and food to China.

MRI method for measuring MS progression validated

A new MRI approach called quantitative susceptibility mapping (QSM) has been validated for measuring Multiple Sclerosis (MS) progression. QSM provides a quantitative way to measure myelin content and iron deposition in the brain, which are important factors in MS physiology. The study demonstrated that using the correct model can separ...

Beyond Mendel

The Student DNA Barcoding Project is a flexible curriculum that uses student-generated research to teach about biodiversity, ecology and molecular biology. The project has been successfully used in New York City and Belize, with students exploring topics such as beetles, beehives, and conservation.

Helping good genes win in brain cancer cells

A study published in Molecular Neurobiology found that sodium butyrate reduces survival of cultured medulloblastoma cells and enhances expression of markers for a mature neuronal phenotype. This suggests the compound may promote cell death and favor maturation towards less malignant-prone phenotypes.

An increase of just 2,000 steps a day cuts cardiovascular disease risk by 8 percent in those with a high risk of type 2 diabetes

A daily step increase of just 2000 steps can cut the risk of cardiovascular disease by 8% in those with a high risk of type 2 diabetes. The study, which analyzed data from 40 countries, also found that increasing physical activity levels through walking can substantially reduce the risk of heart attack and stroke.

Evolution of plumage patterns in male and female birds

Research by Thanh-Lan Gluckman reveals that plumage patterning is labile in both males and females, with changes driven by environmental factors and signalling functions. The study challenges traditional views on sexual dimorphism, suggesting multiple types of dimorphism and adaptations to social and environmental conditions.

A new -- and reversible -- cause of aging

Researchers at Harvard Medical School have discovered a reversible cause of aging in mammals. Administering a naturally produced compound restored communication between cells' nucleus and mitochondria, comparable to younger animals. This finding has significant implications for understanding the aging process and potential reversal.
