Contributions of Limb Joints to Energy Absorption during Landing in Cats

Contributions of Limb Joints to Energy Absorption during Landing in Cats SUMMARY: How is it that cats are able to jump down from high places and not hurt themselves? Researchers in this study observed 5 cats, jumping from various heights, for clues as to what sorts of forces and shock absorbers were at work. The… Continue reading Contributions of Limb Joints to Energy Absorption during Landing in Cats

Using NAC Against Antibiotic Resistance Bacteria

N-acetyl Cysteine Coated Gallium Particles Demonstrate High Potency against Pseudomonas aeruginosa PAO1 SUMMARY: Antibiotic resistant bacterial infections are on the rise, especially in hospitals. One of the culprits is the bacteria Pseudomonas aeruginosa (POA1). Researchers are quickly running out of antibiotics to use against resistant strains. The problem has reached the point where colistin, a… Continue reading Using NAC Against Antibiotic Resistance Bacteria

Rotifers Paralyzing Schistosomes

A rotifer-derived paralytic compound prevents transmission of schistosomiasis to a mammalian host SUMMARY: Researchers discovered that a new molecule produced by the rotifer, Rotaria rotatoria, paralyzes cercariae. Cercariae are the free-living/infectious stage of the flatworm Schistosoma, the cause of schistosomiasis. R. rotatoria live on the shell of freshwater snails and secrete a compound scientists have… Continue reading Rotifers Paralyzing Schistosomes

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
