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.
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.
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.
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.
Scientists around the world continue to be concerned about the amount of pollution created by modern industrialization. With emerging nations such as China and India, more people have access to luxuries like cars that produce waste and contribute to climate change. All these factors influence the environment and the affect the animals of the planet. In particular, blue whales are among some of the hardest-hit species at the turn of the century.
Those of us who are drivers have all heard the question, “Do you want to be an organ donor?” If a deceased person is an organ donor, a hospital can remove their organs and transplant them into a patient who is in critical need. By having drivers sign up as donors, our health system is creating a supply of organs needed to save lives.
While Hopkins may be considered a small campus by many students, sometimes it’s a drag to travel from Bloomberg to Olin (those unfortunate souls in discrete math may know the pain). If only getting around campus could be easier! Bikes are an obvious solution to the excruciating walks. However, currently, the university does not offer a bike rental program. For the majority of us who don’t have a bike—or don’t want to pay for one—there is a shining beacon of hope on the horizon. A group of students on Homewood have decided to create an organization called Jay Bikes.
As the world’s population continues to grow, the planet’s ability to support life is being stretched to its limits. In fact, models on Earth’s carrying capacity suggest that the planet cannot sustain current growth rates. If changes are not made, food and water shortages will span the globe in the near future. Some scientists believe that the only way to avoid such crises is through a second Green Revolution, in which global food production significantly increases.
saster, it is heartwarming to see an army of volunteers trying to help victims recover. These volunteers do a significant amount of work: They clear debris from roads, move food and other supplies to accessible areas and offer words of kindness in moments of despair. Many of them, such as those working for the Red Cross, are specifically trained for their tasks. Some, however, arrive on the scene without any preparation. A recent study suggests that these untrained volunteers may not be as helpful in disaster situations as we would like to believe. In fact, because these untrained volunteers often act spontaneously, they might even harm the relief efforts.
As spring progresses, the sun rises earlier and earlier each day. With the hassle of adjusting our clocks and the arbitrary changes in our sleep schedules, most of us have probably, at one time or another, wondered about the origin of daylight savings time.
For the past few decades, America has been at war against obesity. Cheap, high fat foods are continuously tempting our front lines and indiscriminately adding inches to our waistlines. To combat this growing problem, schools, businesses and healthcare institutions across the nation have tried to increase awareness of obesity and its causes. Despite the numerous health talks and active lifestyle initiatives, a Hopkins study suggests that the key player in weight loss may be the discussions patients have with their doctors about weight.
We are all familiar with the concept of the Freshman Fifteen. Thanks to academic stressors and buffet-style cafeterias, the first year of college is nearly synonymous with weight gain. Even at Hopkins, most students put on a few pounds in the first couple of months.
Imagine a rapidly spreading disease that kills millions of people with no cure in sight. Families are resigned and yet panicked, alive and yet dying inside.
Any amateur baker is familiar with the importance of yeast. This microorganism, which eats sugars and produces carbon dioxide as a byproduct in the process, leavens bread. However, the power of yeast extends far beyond bread-making. Researchers under Hal Alper, an assistant professor in Cockrell School of Engineering of The University of Texas at Austin, have managed to create a new yeast strain that can create enormous amounts of lipid from simple sugars. These lipids can be converted into fuel, potentially alleviating the approaching oil shortage.
Obesity levels in the United States have steadily increased in recent years. Public media has drawn attention to the growth of this condition often describing obesity as a national epidemic. Medically, obesity is classified as a condition in which an individual’s body mass index (BMI), a quantity calculated by dividing the weight in kilograms by the square of the height, exceeds 30. Obesity increases the probability of developing other conditions including cancer and fatty liver disease. While some of these obesity-linked ailments are incurable, researchers at Hopkins have found a drug that can combat one of them. The Hopkins research team discovered that a common medicine for epilepsy can be used to alleviate fatty liver disease.
In modern day society, countless wifi, radio and microwave signals are given off from electronic devices such as cell phones. These signals are essential in connecting people to social media and to each other. However, manufacturing signals requires energy that is wasted after they finish transferring their information. In the face of a looming energy crisis, scientists are searching for methods that can convert these signals into usable energy, minimizing the loss of energy when an electronic device is used. A promising method has been discovered recently by a research team led by Steven A. Cummer, an electrical and computer engineering professor at Duke University.
Robots are the main feature in countless sci-fi movies. They are usually extremely intelligent, resilient and, sometimes, eerily indistinguishable from flesh-and-blood humans. On the contrary, current generations of the robots are crude attempts at imitating those in the movies. Robots in use today are often bulky instruments used for industrial manufacturing. There are some, however, that are being produced which aim to resemble the intelligent machines portrayed on the big screen.
Over the past decade, the scientific community has agreed that the average global temperature is rising. Some attribute this increase to the production of greenhouse gases; others believe that the rising temperatures are part of a bigger cycle, consisting of warm and cold periods. Nevertheless, there is an evident rise in temperatures. Recently, a research team from the University of Colorado Boulder presented convincing evidence that global warming is a result of greenhouse gas emissions.
Where did we come from? How come we, as humans, seem so different as compared to others in the animal kingdom.
Many Americans are rather familiar with the current energy crisis. As the world population continues to grow, available fuel deposits and supplies continue to dwindle. Some estimate that the Earth will reach an energy shortage epidemic in the next 50 years.
