A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management?

PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community?

The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification. #### How does PMI support social impact? PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives.

A team from Weill Cornell Medical College collected DNA samples from places like handrails and benches across 466 stations over a period of 18 months and sequenced the genetic material to determine exactly who—or what—was living in the underground metropolis, the Wall Street Journal reports. The researchers identified 15,152 types of life forms, ranging from rodents and insects to the bacteria that cause the bubonic plague — though the city’s Department of Health and Mental Hygiene disputes that last claim, noting that bacteria doesn’t occur naturally in the region. Among the most commonly identified DNA came from bacteria that cause food poisoning and bacteria that cause urinary-tract infections, though the researchers said the levels detected did not pose a public health risk, the Journal reports. Other genetic material found throughout the system provided something of a map of New Yorker’s culinary tastes, including the bacteria found in the mozzarella cheese on pizza and the bacteria found on kimchi and sauerkraut. The most fertile station? The Myrtle-Willoughby Avenues G train stop in Bed-Stuy, where at least 78 unique bacteria were identified. (The Journal has put together an [interactive graphic](http://graphics.wsj.com/patho-map/?sel=stn%5F164) to show you the specimens found at your station) Read more at the [Wall Street _Journal_](http://www.wsj.com/articles/big-data-and-bacteria-mapping-the-new-york-subways-dna-1423159629) ## Transcript Germaphobes, you've been warned. Every fear you've probably ever conceived is in the subways of New York City. But don't worry too much, there are still a whole lot of things keeping. Keeping you healthy down there too. A bacteria mapping project from Cornell University researchers wanted to document both, microorganisms and DNA recovered from everyday surfaces on a city- wide scale. And, what better way to get samples representing the full gamut of the population, than the subway. The results? Nearly half of the DNA, 48 % does not match any known organism. If you're not sufficiently freaked out just yet, the lead researcher, Chris Mason, says traces of bubonic plague were found uptown. And in the southern part of the city, Mason told the Wall Street Journal bacteria found there had only previously been seen in Antarctica. That could have something to do with Superstorm Sandy in 2012, which slammed South Ferry. Station. Speaking of the astounding amount of dust and other DNA researchers found Mason also said essentially all of the rats or mice that you might see in the subway as the train goes through it kicks up the air and then coats the entire subway system like snow of their DNA. Now, everybody just calm down. While the scary or gross microorganisms in DNA are going to make headlines, there's also an astounding number of microbes essential for positive things like consuming waste. One of the most important notes of this entire research is that we're surrounded by hundreds of millions of trillions. of bacteria, and yet most of us are just fine. They're just us, they're not, this alien invasion force of, of, evil bacteria . >> Researchers say they're hopeful mapping systems can lead to major cities being able to tell how and whether disease spread through the population detect bio- terror threats, and maybe even how to predict areas that people should avoid if there is an outbreak. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3697797/new-york-city-subway-germs-bacteria-dna/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3697797/new-york-city-subway-germs-bacteria-dna/"},"headline":"DNA Tests Confirm NYC Subway Is a Germaphobe's Worst Nightmare","datePublished":"2015-02-05T20:38:57.000Z","dateModified":"2026-10-01T09:02:43.280Z","description":"There really are lowlifes on the subway","url":"https://time.com/3697797/new-york-city-subway-germs-bacteria-dna/","keywords":["Transportation","New York City","subway","health","Germs"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltc32a20c1fcb36f16/69877dd5cd1bba3e116f5116/157664943.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Noah Rayman","jobTitle":null,"url":"https://time.com/author/noah-rayman/"}],"articleSection":"U.S.","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltc32a20c1fcb36f16/69877dd5cd1bba3e116f5116/157664943.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"New York City Subway Pushing Death Puts Spotlight On Commuter Safety","caption":"New York City Subway Pushing Death Puts Spotlight On Commuter Safety","creditText":"Spencer Platt—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/us/","name":"U.S."}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/3697797/new-york-city-subway-germs-bacteria-dna/","name":"DNA Tests Confirm NYC Subway Is a Germaphobe's Worst Nightmare"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"Half Of DNA, Bacteria In NYC Subways Are Unknown","description":"Germaphobes, you’ve been warned.
