Drug reactivates silenced genes

By JOSH SCARALIA | March 27, 2014

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.

Wearable technologies progresses

By SEAN YAMAKAWA | March 27, 2014

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.

Facebook looks to link the world with drones

By JOEL PALLY | March 27, 2014

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.

Scientists track primate evolution via RNAs

By SUNNY CAI | March 27, 2014

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.

Toothy tumor discovered in brain

By KELLY CARTY | March 13, 2014

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.

Homophobic prejudices reduce lifespan

By SAMHITA ILANGO | March 13, 2014

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.

How could a Boeing 777 simply vanish?

By SOPHIA GAUTHIER | March 13, 2014

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?

Taxonomy is revamped in DNA-based system

By SEAN YAMAKAWA | March 13, 2014

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.

NASA discovers 715 new planets

By JOAN YEA | March 13, 2014

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.

CarPlay brings Siri into travel

By MIKE YAMAKAWA | March 13, 2014

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.

Hopkins uses immune cells to battle cancer

By MARU JAIME GARZA | March 13, 2014

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.

Hopkins study challenges food regulation agencies

By ELIZABETH LIU | March 13, 2014

Agricultural regulatory agencies, the governmental organizations that oversee food production and research, are regulated themselves by the red tape of bureaucracy. A study from the Johns Hopkins Center for a Livable Future (CLF) discovered that, under current circumstances, industrial food animal production (IFAP) regulatory agencies are not able to do their jobs effectively.

Insomniacs possess higher neuronal plasticity

By Catie Paul | March 13, 2014

Think back to the last time you had trouble sleeping. Remember how you felt lying in bed awake, gazing into a dark room until your clock finally told you to start a new day. Now, imagine having trouble falling asleep or staying asleep every night.

44-year-old “stone baby” found in elderly woman

By SOPHIA GAUTHIER | March 6, 2014

Pregnancy is one of the most strangely beautiful mysteries of life. In slightly less than a year, a tiny new person is fashioned through a laborious, yet gratifying algorithm of biology. But what if pregnancy lasted longer, say several decades, and never even produced a viable offspring?

Music and language are not created equal

By REGINA PALATINI | March 6, 2014

Like language, the composition of music involves combining separate elements into structured and meaningful sequences. An example is the musical exercise of “trading fours.” This time-honored tradition among jazz musicians describes a pattern in which two solo musicians alternate playing four measures each, usually after each person has played a solo. Beginner musicians, especially drummers who are inexperienced in playing jazz, often find this exercise difficult. It is a skill that is only learned after much practice and determination.

Adhesive designed from gecko toes

By SUNNY CAI | March 6, 2014

In our increasingly environmentally conscious society, consumers often opt for reusable versions of frequently used items such as shopping bags or water bottles. Unfortunately, reusable varieties are not available for all items. For example, tape, one of the most commonly used supplies, does not come in a reusable strain. At least not yet.

New stem cell research under investigation

By KELLY CARTY | March 6, 2014

Groundbreaking research on stem cells presented by Haruko Obokata of the RIKEN Center for Developmental Biology has recently come under serious scientific scrutiny. Concerns about the research data and the reproducibility of the results have prompted Nature and the RIKEN Center to launch investigations into Obokata’s original work.

Medical judgment stunts weight loss

By TONY WU | March 6, 2014

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.

Alcohol inhibits body's ability to build muscle

By MARK STUCZYNSKI | March 6, 2014

What’s a better way to celebrate a hard-played game than by having a few drinks (provided you’re over 21)? According to a study by exercise scientists in Australia, quite a lot, especially if you want to maintain the health-related gains associated with exercise.
