Mendel’s Principles of Inheritance
This summer, we celebrate the 200th birthday of Gregor Mendel, known as the father of modern genetics. Mendel was an Augustinian monk in what is now the Czech Republic whose pioneering experiments uncovered the basic principles of inheritance. Between 1857 and 1864, Mendel meticulously crossbred thousands of pea plants with various traits (such as height, pea shape, and pod shape) and systematically recorded how those traits were passed from one generation to the next.
Although his scientific achievements went unrecognized during his lifetime, Mendel’s work anticipated the field of genetics, long before the discovery of DNA and genes. Our modern understanding of how traits may be inherited through generations comes from the principles of inheritance proposed by Mendel.

Functional Neurological Disorders
Functional neurological disorders are a collection of disorders in which patients experience neurological symptoms, such as numbness, weakness, seizure-like events, or abnormal gait or movements, but without a visible underlying pathology. Underlying mechanisms for these disorders are incompletely understood but the prevailing theory is that the symptoms are related to psychological factors.

Cardiac Care in Duchenne Muscular Dystrophy
Cardiac disease is a major cause of mortality in Duchenne muscular dystrophy (DMD), yet data regarding outcomes and cardiac disease progression are lacking. This has led to a highly variable approach to heart failure therapy in DMD from center to center, according to a new report that surveyed pediatric cardiologists within the Advanced Cardiac Therapies Improving Outcomes Network (ACTION), a multicenter heart failure quality improvement network.

Do Dolphin Signature Whistles Function as Names?
It was not known whether dolphins could use signature whistles the way that humans use names; that is, as a representational label (a call that can stand in for an object the way a noun can in our language). So, in a new cross-modal experiment, researchers tested if dolphins could recognize familiar individuals from their signature whistle and the taste of their urine.

Kea Cognition and Conservation
New Zealand’s mountain parrot, the kea, is known for its curiosity and intelligence. Can an understanding of kea behavior and cognition be applied to their conservation in the wild?
