Researchers at California Institute of Technology (Caltech) in Pasadena, Calif. have recently discovered evidence of “Planet Nine,” a giant planet located at the outer edges of the solar system.
The current Zika outbreak has spread to more than 20 countries in Latin America and the Caribbean, and the World Health Organization (WHO) estimates that it will infect another four million people by the year’s end.
Researchers in the Department of Neuroscience at the Johns Hopkins University School of Medicine have found that high doses of cocaine in mice kill brain cells by way of overactive autophagy, a “housekeeping” process through which cells rid themselves of debris and waste.
Complex organisms like humans are made of trillions of cells that can communicate with each other to coordinate actions. During development, when a cell’s identity is being determined, the chemical environment around a stem cell influences its differentiation into a specific type of cell. A cell can sense the concentration gradient of a chemical signal in its environment, causing the cell to move in a desired direction and then proliferate.
Sick with a sinus infection, strep throat or pneumonia, you were probably prescribed antibiotics. In fact, antibiotics are the primary method of treatment for most bacterial infections. The drugs, while often very successful, have resulted in unforeseen consequences since the beginning of their use.
The next time you enter a classroom for a test, you might want to choose a seat that has a view of a green landscape. You may do better on the test and be less stressed, according to the results of a recently published study.
There is not much debate anymore about the effects of cigarette smoke on health — the Centers for Disease Control and Prevention (CDC) states that cigarette smoking is the leading preventable cause of death in the U.S. and causes at least 480,000 deaths per year.
One in 68 children in the U.S. have been diagnosed with a developmental condition that falls under the umbrella of autism spectrum disorder (ASD). The number of diagnosed cases of ASD is increasing over time, as is the medical community’s understanding of autism. As of now the exact mechanisms underlying the development of autism are not fully understood. However a new study has shed light on a region of the brain whose folding activity is correlated with the display of autistic symptoms.
The Modular Prosthetic Limb, developed by the Johns Hopkins University Applied Physics Lab (APL), has achieved new levels of operability thanks to a pioneering surgical procedure that allows the prosthetic to be directly and biomechanically attached to the amputee’s bone.
The search for life outside of planet Earth has captivated science fiction writers, astronomers and society at large. However, the likelihood of finding such life is continually restricted by the limitations of technology and the sheer size of the universe.
Everyone knows that climate change caused by carbon emissions is harmful to the environment. It causes rising sea levels, loss of biodiversity, reduced agricultural yields, constrained water supply, unpredictable weather patterns and more. New research from the University of New South Wales (UNSW) in Australia indicates that there might be yet another consequence to worry about: drunken fish.
Osteoporosis, a disease that results from an imbalance between bone resorption and bone growth, affects millions of Americans each year. Patients who suffer from this disease have weakened bones that fracture easily under impact, causing pain and problems in mobility. The patient usually does not realize that he or she has osteoporosis until he or she experiences the onset of constant back pain or a sudden fracture. To lower the risk of osteoporosis, doctors recommend exercise and a healthy diet, but there remains no treatment for osteoporosis-related injuries once the patient has the disease.
A recent study done by the University of Sheffield’s Department of Geography discovered that water from melted giant icebergs supports extremely high levels of phytoplankton growth. This melted water contains iron and other nutrients and contributes to an activity known as carbon sequestration.
Neuroscientists at Johns Hopkins Medical School have found that compound CGP3466B successfully delivers antidepressant effects to mice within mere hours. This compound, which has previously been shown to block cocaine craving in mice, rapidly delivers antidepressant effects when compared to most drugs, which can take weeks or even months.
