In recent years, the rapidly evolving world of 3D printing has given rise to numerous products that serve functional or aesthetic purposes. In an ambitious effort, scientists even successfully engineered simple human tissues using 3D printing. However, the latest breakthrough in the field is the creation of a product whose intricacy and complexity exceeds many’s expectations — a complete heart.
When Charles Darwin observed the wide variety of species in the Galápagos Islands, he may have been unknowingly contributing to it. A new study in Aquatic Invasions shows that 10 times more non-native aquatic species are present on the islands than previously thought.
On Monday, March 25 the New Jersey state legislature passed a new bill that would legalize the practice of assisted suicide for its state residents. This was the first time that the bill went to an actual vote in the New Jersey Senate, where it narrowly passed.
To this day, many people still recall the widespread Zika outbreak in the wake of 2016 that caught the majority of South and North America off guard. In November 2016, the World Health Organization (WHO) declared the end of the epidemic after many months of struggle.
Many people might recall an experience where simply looking at an image of someone yawning triggers them to yawn. This is no magic; in fact, it is a popular phenomenon known as contagious yawning. Studies in the past have shown that approximately 50 percent of adults would yawn in response to other people’s yawning.
Darwin’s theory of evolution has been around for nearly 200 years, but its influence does not appear to subside with time. Not only is the topic of evolution a required biology curriculum in schools across the world, but it has also been cited in numerous research studies and papers. Today, it is still driving the forefront of molecular research. In fact, research conducted on the basis of Darwin’s theory of natural selection has recently led scientists to claim the 2018 Nobel Chemistry Prize.
As early as Hippocrates’ time, people have pondered on the best way to classify personalities. In fact, Hippocrates came up with one of the oldest personality type systems in the world, where he defined four personality types based on a person’s “humor” or the proportion of bodily fluids in one’s body. The predominant form of fluid determines the person’s appearance, behavior and psychological type.
This past weekend, students and healthcare professionals from across the country gathered at the annual MedHacks competition hosted by Hopkins students.
Sleeping is often considered one of the most primitive and mundane aspects of biological existence. Some scientists claim that it is a survival instinct that has evolved for millions of years. However, despite its ancestral roots, sleep is not very well understood. In fact, countless mysteries take place when we sleep: How does the mind create dreams? Do dreams come in colors or black-and-white? Most importantly, how does the brain sustain and maintain high levels of activity during certain periods of the sleep cycle?
Among the diversity of species that roam the Earth, a small subset of them have gradually evolved into some of social media’s favorite icons.
The Milky Way Galaxy is more than 100,000 light years in diameter. In between this vast space occupied by so many unknowns, how do humans advance their quest in determining the existence and locations of black holes?
Prosthetics is a focus area in biomedical engineering that has been constantly expanding. Recently, scientists came up with a novel way of incorporating a person’s prosthetic memory system into regulatory brain processes such as encoding and retrieving memories.
There is often the notion that DNA is a set of permanently stable biological sequences, but in reality, the genetic code is far more complex than most people think.
A newly published study from Harvard Medical School revealed that survival rates for heart attacks can sometimes increase when cardiologists are away from their patients at academic conferences.
An oncovirus is a type of virus with a DNA or RNA genome that can cause cancer.
The idea of “mind-reading” has commonly been associated with magic or the supernatural. However, research done at a lab in the University of Toronto Scarborough (U of T Scarborough) recently took a significant stride forward in achieving this possibility.
Trisomy 21, also known as Down syndrome, is one of the most well-known forms of genetic conditions. The incidence of trisomy 21 is one in 700 live births.
Imagine the thousands of enzymes that are required to maintain a healthy and functional human body. It might be surprising to find that some of these enzymes are so evolutionarily significant that they are present in almost every animal species on Earth. One of these ubiquitous enzymes is known as RNA Polymerase III (RNA Pol III), which is indispensable for regulating the production of proteins.
Geological investigations can often speak volumes to scientists who are studying the impacts of climate change.
