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

Do Full Moons Cause Behavioral Changes?

Exploring the Potential Psychiatric Implications of Astronomical Phenomena SUMMARY: This study looked at the effect of the full moon and other astronomical phenomena on behavior. Researchers recorded the number of incidences (restraints, seclusions, and code green emergencies) that occurred in a psychiatric hospital in Buffalo, NY for 5 years. The results showed no correlation between… Continue reading Do Full Moons Cause Behavioral Changes?

CO2 emissions from subaerial volcanoes

The emissions of CO2 and other volatiles from the world's subaerial volcanoes SUMMARY: Volcanoes play an important role in recycling carbon dioxide. This study takes a closer look at the amount emitted into the atmosphere by volcanoes that aren't underwater. Out of 900 volcanoes, only 500 have detectable degassing activity (i.e. they are emitting gases).… Continue reading CO2 emissions from subaerial volcanoes

Donkey’s Milk in the Management of Children with Cow’s Milk protein allergy

Donkey’s Milk in the Management of Children with Cow’s Milk protein allergy: nutritional and hygienic aspects SUMMARY: Doctors and scientists have been looking for a good cow-milk (CM) substitute for the 4% of kids who have severe CM allergies. Unfortunately, goat and sheep milk often contain proteins that are similar to those found in CM… Continue reading Donkey’s Milk in the Management of Children with Cow’s Milk protein allergy

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
