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

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
Electronic Tongues
A Versatile Electronic Tongue Based on Surface Plasmon Resonance Imaging and Cross-Reactive Sensor Arrays-A Mini-Review SUMMARY: Scientists are trying to create electronic tongues (eT) and noses (eN) that act like human tongues and noses. These artificial sensors are different from traditional sensors in that they don’t recognize individual molecules, but heterogeneous liquids and gases. In… Continue reading Electronic Tongues
Enzyme Catalysis To Power Micro/Nanomachines
Enzyme Catalysis To Power Micro/Nanomachines SUMMARY: Is it possible to make nanomachines out of enzymes? This review looks at the ways we can harness enzymes to self-propel or function as tiny machines. Doing so would have many implications in nanotechnology and drug delivery. There were a few ways to use enzymes. First, there's the DNA-enzyme… Continue reading Enzyme Catalysis To Power Micro/Nanomachines
Beaming Pyrimidines Part 2
Thymine and Other Prebiotic Molecules Produced from the Ultraviolet Photo-Irradiation of Pyrimidine in Simple Astrophysical Ice Analogs(NOT OPEN ACCESS) SUMMARY: In the second edition of beaming pyrimidines, instead of using ammonia, scientists beamed pyrimidines with methanol, water and methanol, methane, and water and methane. As with “Beaming Pyrimidines Part 1”, the gases were cooled way… Continue reading Beaming Pyrimidines Part 2
Beaming Pyrimidines Part 1
Nucleobases and Prebiotic Molecules in Organic Residues Produced from the Ultraviolet Photo-Irradiation of Pyrimidine in NH3 and H2O + NH3 Ices (NOT OPEN ACCESS) SUMMARY: If you beam water and pyrimidines at low temperature and pressure in a sealed chamber, you’ll produce pyrimidine-based molecules such as uracil, cytosine, isomers of uracil and cytosine. You’ll also… Continue reading Beaming Pyrimidines Part 1
