It is hard to fathom that animals as complex as humans evolved from tiny microscopic organisms. A recent fossil discovery may provide more insights into how exactly the evolution from single-celled forms of life into the intricate life forms alive today happened.
Turmeric, known scientifically as Curcuma longa, does more than just add spice to the curry eaten all over the world. Native to southeast Asia, the orange and yellow plant has been used for centuries not just as a dye or a spice but also as a medical treatment. A lab in Germany has recently brought turmeric back into the medical playing field. The study, done by Maria Adele Rueger and her team, tested the compound’s utility in relation to diseases of the brain.
Before the advent of modern neuroscience, the brain was viewed as an impenetrable box.
September was likely the highlight of the year for smartphone enthusiasts everywhere. Not only were they treated to the long-awaited iPhone 6 and 6 plus, but now BlackBerry has decided to contribute to some of the ongoing buzz with their own new invention: the BlackBerry Passport.
This week the Nobel Assembly at Karolinska Institutet awarded the Nobel Prize in Physiology or Medicine, and The Royal Swedish Academy of Sciences awarded the Physics and Chemistry Prizes. The science prizes recognized achievements from nine scientists over the past 50 years.
There aren’t many immediate obvious similarities between malaria and Coca-Cola... except when they intertwine in the field of public health. They are able to converge because the economic influence and marketing practices of one is being used in combatting the other.
Harry Potter fans, rejoice: Researchers from the University of Rochester have discovered an inexpensive way to recreate the fictional wizard’s famous invisibility cloak.
In the past week, Ebola has turned from a threat on a distant continent to something very real for Americans. Thomas E. Duncan is the first person to be diagnosed with Ebola in the United States, as confirmed by the Centers for Disease Control (CDC) on Sep. 30. Duncan died from the disease yesterday in a Dallas hospital.
Picture the Milky Way galaxy: our home, and the only galaxy that humanity has ever known. It is large and serene, a spiral of incredible beauty and unimaginable proportions. It is an inspiration to artists, philosophers and candy bar manufacturers alike. The earth resides peacefully in this galaxy, calm and seemingly endless — but the conditions of the Milky Way are far from static. In fact, our home galaxy will soon eat other galaxies and in turn be “eaten” — that is, merge with smaller dwarf galaxies. When this happens, life as we know it will cease to exist. This desolate finding was published recently in the prestigious journal, Monthly Notices of the Royal Astronomical Society, which is produced by the Oxford University Press.
A central tenet in biology holds that structure yields function. Whatever the cell does is significantly influenced by its morphology, or shape. For example, the morphology of neurons in the nervous system guides communication. On a macroscopic level, neurons talk to each other in circuit-like networks. Neurons with long axons (one meter or even longer) will be able to communicate with other neurons located far away, whereas neurons with short axons (one micrometer, or 0.1 percent of a millimeter) talk to each other in small localized circuits.
For over 15 years, the Johns Hopkins Applied Physics Laboratory (APL) has developed technologies to assist in the study of public health in order to detect and prevent the spread of disease. These technologies are designed to be easily distributable and open source, meaning that anyone can look at their design.
Contrary to what many Hopkins students seem to believe, a good night’s sleep is essential for optimal physical, mental and emotional functioning. Despite the recognized importance of sleep, the brain structures responsible for sleep regulation are still relatively unfamiliar territory. However, several research pioneers have started blazing the trail into the wilderness of the neuroscience of sleep.
Today it seems that nearly every industry has a product claiming to combat aging: supplements, skin creams, workouts, foods, juice, yoga and even pillowcases (which claim to prevent the skin from losing moisture). But many of these inventions leave much to be desired once their claims are evaluated in an unbiased way, and they produce results that are often far from optimal.
From the recent Ebola outbreak in West Africa to the race to find a catch-all cure to cancer to the eminent flu season at Hopkins, public health issues are consistently at the forefront of the national dialogue.
For years, it has been known that diabetics are at a higher risk for cardiovascular disease (CVD) and heart attacks. In August of this year, though, the Bloomberg School of Public Health (JHSPH) released news of groundbreaking research that sheds light on the link between diabetes and CVD. The risk of heart attacks in diabetics and pre-diabetics can be detected and monitored using an improved test designed to measure evidence of chronic heart muscle damage in diabetics and pre-diabetics.
The Ebola epidemic has been acknowledged as a serious international threat, but the efficacy of measures required to contain the outbreak remains debatable. This is due to the lack of resources in the most affected West African countries: Sierra Leone, Guinea and Liberia.
Perhaps the most interesting conundrum of neuroscience is the nature of human consciousness. How does the three-pound mass of spongy brain tissue composed of approximately 100 billion neurons drive all aspects of the conscious mind, from emotions to creativity?
People take their own lives at a rate of nearly one million deaths a year, according to the World Health Organization (WHO). There are innumerable causes to this issue, varying from isolation, loss and abuse to even sunshine, as a research group at the Medizinische Universitat Wein, the Medical University of Vienna, has recently found.
Sure, the new iPhone 6 is equipped with a new retina HD display, A8 chip for greater power and a better battery for more juice — all tucked into a thinner container. However, these are not new buzzwords that we are just hearing today. A prettier display, faster processor, and longer battery life has been a constantly renewed promise by manufacturers since the advent of cell phones. The iterative improvements in the resolution and chips have become a tad mundane for the itching consumer anticipating the unpredictable. Where has the novelty of touch screens and double-digit megapixel cameras gone?
It’s now the age of the smartphone, and no one lets you forget it — not even the Metropolitan Museum of Art (Met). Ranked one of the top 3 museums in the U.S. according to the 2014 TripAdvisor Traveler’s Choice Awards, the Met has just increased their popularity even further by releasing a new app for visitors.
