Genetic studies are indispensable tools for developing a comprehensive understanding of diseases, particularly cancer and psychiatric illnesses. Many investigators compare the genetic backgrounds of healthy and sick populations to identify the proclivity of specific factors in the genome to certain diseases.
Citizens of the rural town of Oso, Wash. were greeted by tragedy on Mar. 23 as a waterlogged hillside gave way and unleashed a tsunami-like wave of earth, destroying dozens of homes residing in the river valley below.
While they are not yet the cinematic experience of Minority Report, crime scene investigations are becoming more and more like sci-fi crime dramas. Researchers from Erasmus University in the Netherlands, the Catholic University of Leuven in Belgium and Pennsylvania State University stateside have identified genetic determinants of facial structure. With these markers, the collaborators believe it will be possible to reconstruct criminal facial shapes from DNA evidence alone.
Have you ever tweeted about having the flu? While such a message will certainly gain sympathy from friends and family, it may be even more useful than you think. New research is attempting to use Twitter to track the flu throughout the country.
Physicists at Harvard’s School of Engineering and Applied Sciences have proposed a method to harvest energy from Earth’s infrared emissions. Because our planet is warm, especially compared to the cold void of space, physicists believe a significant amount of energy is transferred at the border between Earth and space. These particular physicists think that it may be possible to take advantage of this transfer and harvest the energy for our own use.
At first glance, there seems to be almost no connection between Amyotrophic lateral sclerosis (ALS) and Frontotemporal dementia (FTD), two neurological disorders. However, a team of researchers at Johns Hopkins University School of Medicine recently found that these frightening disorders may share the same cause.
A few years ago, it seemed that everyone was talking about the Atkins diet, a low-carb and high-protein approach to losing weight. Protein was touted as the dieter’s holy grail: It would lead to weight loss while still maintaining muscle mass. The Atkins diet was even voted one of the best diets of 2014 by U.S. News and World Report. New scientific data, however, could make high protein diets a thing of the past.
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.
Examination of stained post-mortem brain slices of children with autism suggest that the condition starts in the second and third trimesters of pregnancy during brain development.
Researchers at Hopkins have discovered a set of genes that are turned off by cancer cells in their attempt to hide from the immune system. These genes were discovered by treating breast, colorectal and ovarian cancer cell lines with the FDA-approved drug 5-azacitidine. This drug, which reactivates silenced genes, exposed 16 different immune system related pathways that have decreased expression in cancer cells. Such decreased expression allows cancer cells to more easily invade tissues.
Demand for new electronic devices from the smartphone and tablet industry has recently simmered somewhat. Their markets are saturated. The newest processors or razor sharp displays aren’t as enticing as they once were, as last year’s models often hold up against the new competition. Some electronic companies have shifted focus to the low-end market, but their budget-friendly products are not flagship devices. To show their technological prowess and re-excite consumers, manufacturers have found a new focus for their industry in 2014: smartwatches.
Internet use has become such a ubiquitous part of everyday life, it is hard to imagine living permanently disconnected from the World Wide Web. Even when our eyes aren’t glued to a screen, our mobile devices are set to pull emails, Facebook statuses, instant messages, sports scores or breaking news at a minute’s notice. The internet, particularly through social media, has forged a kind of global community. It is easy to forget that the majority of the world, approximately 65 percent, is not plugged in.
Rome wasn’t built in a day. Neither was the human brain. The intricate organ was crafted over millions of years before it developed into the functionally sophisticated masterpiece it is today. Just like the numerous workers who toiled in the hot Mediterranean sun to construct the roads, buildings and aqueducts of Rome, countless different biological components labored for years to construct the neurons, lobes and synapses of the human brain. One class of these biological laborers is microRNAs.
Inherent in its Latin root tumere, meaning “to swell,” a tumor describes an abnormal growth of cells. It is a bodily excess, something indispensible, often necessarily, for proper bodily functions. This modern conception of tumorous growths leaves no room for functional structures in the abnormal mass. Imagine the surprise, then, when a team of doctors at Johns Hopkins Hospital found fully grown teeth in the brain tumor of a four-month-old child.
As today’s world continues to have an increase in expected human lifespan, there may be something holding society back: homosexual prejudice. Recent studies have indicated that there exists a direct correlation between anti-gay stigma and shortened lifespans. The study suggests that the shortened lifespan can affect both those who hold the prejudice and those towards whom the prejudice is directed.
Mystery, intrigue and concern shroud Malaysia Airlines Flight 370 as officials scramble to uncover the missing plane. Such a strange occurrence raises the obvious question: How does a 200-plus passenger jet simply vanish in the first place?
In 1735, Carl Linneaus proposed a system for naming organisms in his publication Systema Naturae. This system, called Linnaean taxonomy, has proven robust as it is still used today, nearly 300 years after its original proposal. In this taxonomy, each organism is divided into one of three kingdoms, then further classified into different classes, orders, families, genera and species.
Since the first discoveries of planets beyond Earth and our solar system, the human imagination has been fascinated by the idea of extraterrestrial life. In recent years, astronomers spurred by the possibility of finding planetary environments conducive to life have overlooked the seemingly simple task of identifying and confirming new candidates.
Just when you thought that Apple couldn’t become more ubiquitous, the company has released a new device that will be on the market soon. However, it won’t be available through its regular market; the new Apple product will find its way to mainstream consumers through the Geneva Motor Show this week. Apple is coming out with a new car infotainment system that will be fully integrated with iPhone capabilities.
Cancer is no longer restricted to just our bodies. The disease has invaded headlines, pages of books, scientific studies and the public consciousness. Fortunately, however, this non-physiological growth can certainly spark scientific collaborations to fight the bodily form of cancer.
