Bacterial infections are one of the major causes of death worldwide. Even in hospitals, patients often contract infections from the bacteria-filled surroundings. Recently, researchers at the Hopkins School of Medicine have developed a diagnostic system that has the potential of pinpointing superbug infection sites within patients, helping doctors combat their spread.
After the fourth Ebola patient was diagnosed in the U.S., fears of sending American citizens to high-risk countries have escalated. Many healthcare institutions have recently developed standardized procedures for handling contagious bodily fluids of Ebola patients. On Oct. 24, the Johns Hopkins School of Medicine and the Centers for Disease Control (CDC) announced the pending release of an Ebola training module for nurses and doctors.
While dangerous, the study of infectious viruses and bacteria captivates scientists.The interaction between viruses and the human body are critical to the understanding of the spread of diseases. Furthermore, by studying the mechanisms through which virus interacts with the body, researchers are better armed to develop treatments. However, the White House is temporarily halting such studies, worried that labs aren’t taking enough precautions to prevent disease outbreaks.
Learning and memory comprise a fundamental part of our lives, allowing us to keep up with changes in the environment and acquire new information about the world. It is well established that a brain region known as the hippocampus is important for such abilities. However, the mechanism governing hippocampal-dependent cognitive function remains elusive. Recently published in Neuron, a study has shown that the hippocampus retrieves memory by activating networks in the cerebral cortex, providing an insight into the biological basis of learning and memory.
Given a choice between a sugary beverage and water, would you still drink the sugary beverage if you knew how many miles you would have to walk in order to burn off the calories?
A fourth case of Ebola has emerged in the U.S. Dr. Craig Spencer, a physician working for Doctors Without Borders, returned to New York from Guinea on October 17th, but did not exhibit symptoms until Thursday (note: the virus has an incubation period of three weeks). Spencer is being treated at New York City’s Bellevue Hospital Center, one of the eight statewide hospitals designated by New York State Governor Andrew Cuomo to be fully equipped with an Ebola preparedness plan. As part of his treatment, Spencer has received a blood transfusion from nurse Nancy Writebol, a survivor of Ebola who shares his blood type.
At Hopkins, seeing students studying into the early hours of the morning isn’t uncommon, but it’s probably unhealthy. All organisms, from bacteria to humans, have internal clocks to help them synchronize their behaviors to the time of day. A study just recently published in Cell suggests that the biological clocks in gut microbes living in mice and humans are controlled by their host’s circadian rhythms, and when hosts disrupt their circadian rhythms it can lead to health problems like obesity.
Health-food expert or not, you are probably aware that eating broccoli is pretty good for you. A recent study has found yet another reason to like broccoli: a chemical in it may have a beneficial effect on autism. This chemical could become a part of treating autism in the future.
Arctic sea ice levels are becoming more unstable according to an article published by The National Aeronautics and Space Administration (NASA) in its Science News blog on Oct. 15.
How conscious are people in a vegetative state? Although the answer may seem obvious, in actuality it isn’t. A recent study found that some patients who appear unconscious still have hidden brain network patterns that support a level of cognition. This indicates that even though the patients seem outwardly unresponsive, they may be aware of their surroundings and be capable of thought processing.
There are a wide variety of diseases that impair the growth of the brain and nervous system, ranging from autism spectrum disorders to schizophrenia. With this large number of disorders comes an even larger number of treatments, from medications to therapies to surgeries. However, many of these seemingly different neurodevelopmental disorders may share a common cause. One treatment could be developed that would be effective for many different disorders.
Sensory input from the external world profoundly influences homeostasis and evokes complex behavioral output important for health maintenance and survival. One such critical sensory input is light, which allows us to visualize the outside world.
Teachers tell students that math will be useful later in life, but did they know it would be useful at the gas station? A group of Hopkins scientists have developed a mathematical model to estimate how much of a gasoline droplet will infiltrate concrete or evaporate into the air. The model shows that small droplets, which occur frequently during refueling, could damage our environment and our community.
Between wars, accidents, birth defects and diseases like diabetes, there are more than 1.6 million people in the U.S. who suffer from some kind of limb loss. Advances in technology have allowed doctors to fit prosthetics that are comfortable and function well, but there are no artificial limbs that allow patients to regain sensation.
Coffee, that magical elixir some of us swear by during midterms and finals, has been found to genetically affect our bodies. Scientists at the Harvard School of Public Health and Brigham and Women’s Hospital recently released the results of a study that suggests that people naturally adjust their coffee intake to experience the optimal effects produced by caffeine.
Hot off the heels of the September unveiling of new iPhones and a smart watch, Apple introduced two new iPads, new Mac models, and the release of two major operating systems (OS).
America is the birthplace of a multitude of fast food chains like McDonald’s, Burger King, Wendy’s and many more. Perhaps not coincidentally, the U.S. is also facing an obesity epidemic: In 2012, more than one-third of adults were obese. However, a new study has found that restaurants have started voluntarily lowering the calorie count of their menus.
On Thursday Oct. 16, a dedication ceremony for Malone Hall was held in an outdoor pavilion on Decker Quad. Dr. John C. Malone, who contributed $30 million to fund the construction of the building, was honored at the dedication.
“What happens to us after we die?” This question has bewildered mankind since the dawn of human civilization. In attempting to find an answer, mythological traditions and major religions have arisen.
Kabuki syndrome, a newly-discovered genetic disease, has been the subject of several studies aimed at determining its causes and finding potential medications for treating the disease. Recently, a team at the School of Medicine has discovered a potential route for developing drugs that can treat the disease.
