The Endocannabinoid System of Animals

The Endocannabinoid System of Animals SUMMARY: This article talks about the endocannabinoid system (ECS) in animals. The first and second section talks about the three parts of the ECS: receptors (CBR1 and CBR2), ligands (endocannabinoids), and the ligand degrading enzymes. The receptors are G-protein coupled receptors, the ligands bind directly to these receptors, and the… Continue reading The Endocannabinoid System of Animals

Machine Learning in Medicine

Machine Learning in Medicine SUMMARY: This review looks at the various ways people and companies have tried to use machine learning in medicine, specifically to predict cardiovascular issues and cancer. There are two types of machine learning: supervised and unsupervised. Supervised learning uses algorithms to look at data and classify the information. Unsupervised learning takes… Continue reading Machine Learning in Medicine

Anchoring like octopus

Anchoring like octopus SUMMARY: In this experiment, scientists tried to reproduce an anchoring mechanism modeled after octopus suckers. There were a few important aspects they wanted to mimic: the softness of the suckers so that suction could be maintained even on rough surfaces and the ability to sense proximity and tactile stimuli. They ended up… Continue reading Anchoring like octopus

The meaning of blood pressure

The meaning of blood pressure SUMMARY: This article talks about all the physical aspects of blood pressure. The first few sections talks about the 3 forces that affect blood pressure: elastic, kinetic, and gravitational. The author also talks about how kinetic energy can be converted to elastic energy in the case of an aneurysm in… Continue reading The meaning of blood pressure

The physics of pollinator attraction

The physics of pollinator attraction SUMMARY: This article focuses on the physical properties of plants that have evolved to help them select the appropriate pollinators and discourage non-pollinators (nectar stealers). Starting with the shape of the cells, the petals of a flower often have cone shaped cells. This shape helps to scatter more light giving… Continue reading The physics of pollinator attraction

Toxic wavelength of blue light changes as insects grow

Toxic wavelength of blue light changes as insects grow SUMMARY: Different wavelengths of light are toxic to insects. In this study, scientists looked at the different effects of blue light on fruit flies (Drosophila). They found that each developmental stage was more susceptible to different wavelengths. There were also differences between males and females. For… Continue reading Toxic wavelength of blue light changes as insects grow
