Lipid secreted by tumors inhibits immune response against cancer

Researchers at National Jewish Health have discovered how a lipid secreted by cancer tumors prevents the immune system from mounting an immune response against it. When lysophosphatidic acid binds to killer T cells, it acts almost like an "invisibility cloak," preventing T cells from recognizing and attacking nascent tumors.

Regular cannabis users have increased levels of impulsive behaviour, reveals research

New cocaine and cannabis research reveals that regular cannabis users have increased levels of impulsive behaviour. It had previously been argued that this increased impulsivity after cannabis administration was only experienced by occasional users, but that regular users were no longer affected in this way.

Research findings open up possibility for developing potent anti-clotting drugs

Researchers at the University of Illinois at Chicago have discovered a molecular switch that causes small, beneficial clots that stop bleeding to enlarge further during wound healing. By blocking this switch in lab mice, the researchers prevented small clots from growing -- a process that can pose a danger in humans -- while preserving their ability to staunch bleeding

Cognitive reappraisal may have negative effects on psychological health

Being able to regulate your emotions is important for well-being, but new research suggests that a common emotion regulation strategy called "cognitive reappraisal" may actually be harmful when it comes to stressors that are under our control. The study is published in Psychological Science, a journal of the Association for Psychological Science.
