Bee Population Linked to Malnutrition

Pollinators, like bees, fertilize crops high in essential nutrients.

A declining bee population could have a negative impact on countries grappling with malnutrition. A recent study conducted by Rebecca Chaplin-Kramer, a landscape ecologist at Stanford University, examined the link between pollinators (mainly bees) and global health through the lens of nutrition.  Chaplin-Kramer, along with a group consisting of pollination...


Orcas and Dolphins: Communicative Parallels

Orca whales have been shown to have the ability to pick up on vocal cues from animals of different species, including dolphins.

While it may incorporate visual and perceptive components, communication is primarily an auditory exchange between two organisms. Most species use a broad spectrum of words, sounds, grunts, and clicks used to communicate an even wider array of thoughts and emotions. Certain species, humans among them, can learn to mimic the...


Uterus transplantation emerges as a potential cure for uterine infertility

The birth of Vincent, the world’s first baby born from a transplanted uterus, marks the potential for uterus transplantation to combat uterine infertility, a condition that affects women both form birth and after other health conditions like cancer.

A woman successfully gave birth to the world’s first child conceived from a transplanted uterus, demonstrating uterus transplantation as a potential cure to uterine infertility (1). The birth, which happened in early September and was recognized by The Lancet on October 5, marks the initial success of a study conducted...

The University of California San Diego’s School of Medicine has recently identified the part of the brain that controls disappointment among mammals. Researchers have been granted a new insight into why and how people feel disappointed. Seeing the glass half empty may no longer be a matter of perspective, but...


Hearing Affected by Sounds You Cannot Hear

Low frequency waves can cause just as much damage to human hearing as can loud, audible waves.

Researchers led by neurobiologist Markus Drexl at the Ludwig Maximilian University have found evidence that inaudible sounds could cause hearing loss. While many people know that exposure to loud, audible sounds for long periods of time can cause hearing damage, previously, research had yet to show evidence that inaudible sounds...
