Scientists have succeeded in identifying new gene variants associated with an increased risk for myocardial infarction (MI), or heart attack. The identified genes and their underlying mechanisms provide new starting points for understanding genetic patterns in MI and for developing new treatment options. A key finding is that the MI risk is more than twice [...]

Can money make us happy if we spend it on the right purchases? A new psychology study suggests that buying life experiences rather than material possessions leads to greater happiness for both the consumer and those around them. The study demonstrates that experiential purchases, such as a meal out or theater tickets, result in increased [...]

A dividing cell duplicates its chromosomes and its centrosome, an organelle that helps divide the two sets of chromosomes equally to daughter cells, just once. Extra centrosome copies can lead to incorrect distribution of chromosomes, genomic instability and cancer. Now scientists have identified the protein that controls the copying of the centrosome and prevents it [...]

Scientists analyze “free-rider” effects under voluntary vaccination for vaccine-preventable diseases where disease transmission occurs in a social network. Previous studies have suggested that voluntary programs cannot be 100% effective due to the self-interested behavior of individuals. However, most mathematical models used in these studies assume that populations mix homogenously – in effect, that an individual [...]

The genome of a marine bacterium living 2,500 meters below the ocean’s surface is providing clues to how life adapts in extreme thermal and chemical gradients, according to a new article.
Researchers have discovered a new way that bacteria evolve into something that can make you sick. The finding has implications for how scientists identify and assign risk to emerging diseases in the environment.
