How Science is Changing the World

I am a professional teacher, writer, researcher, and learner. I always try to learn because there is no age for learning.


It’s hard to deny that science has made many positive changes in the world, but what exactly do those changes look like? After all, scientific discoveries have had both amazing benefits and devastating drawbacks. As you might imagine, there are many different ways in which science has changed the world over the years. Here are just five examples of how science has influenced our lives and even redefined what it means to be human. These are just five examples of how science has changed the world, but as you can see from this list alone, there are so many others where those came from!

People in the Laboratory


We’re living in a time of exponential technology growth when we can digitally deliver services and information to virtually anyone with an Internet connection. The power of technology has given rise to new industries that no one could have imagined even just a decade ago—from self-driving cars and 3D printing to space tourism and live-streaming apps for pets. Indeed, in many ways, humans are more capable than ever before. In other ways, we haven’t advanced at all: We still war over territory and kill each other over ideology. We still work long hours doing jobs that don’t fulfill us while trying to fill our free time with things that will make us feel better about ourselves but rarely do.


All animals are classified into one of several groups (kingdom, phylum, class, order, etc.). The hierarchy in which they are put is as follows. Kingdom > Phylum > Class > Order > Family > Genus & Species. Bacteria do not fall into any particular group. Humans and all other animals belong to one kingdom: Animalia. Bacteria belong to another kingdom: Prokaryote (for pro-are-toe-ta). Mammals (class) and birds (class) are two separate groups that share some characteristics as well as many others from their own class/grouping.


We recently passed a huge milestone in human history. It was not marked by anything flashy or grandiose, but it is a milestone nonetheless: We have now been on Earth longer than we have been off it. If you were born around 1965, there's about a 50 percent chance that your first breath of air was taken outside of Earth's atmosphere. Currently, an estimated 400 people are living and working in space—but according to NASA, as many as two billion people will be able to afford vacations into orbit by 2050. As our planet grows increasingly crowded and polluted, some question whether humanity can survive without colonizing other planets and moons. Some scientists even suggest that we would have already gone extinct if not for advances in space technology making survival possible here on Earth.


Around 30 years ago, scientists made an amazing discovery. If you treated HIV with a specific type of drug, people who were infected could live for a long time without developing AIDS. This is because HIV has an Achilles heel: It has to bind to certain receptors in human cells, and one class of drugs called protease inhibitors blocks those receptors from working properly. Scientists also realized that they could use another kind of drug to boost the production of a molecule called CCR5. Having plenty of CCR5 allows you to resist HIV infection. Because these two types of drugs are so safe and effective, other researchers have taken them off-patent—and now millions worldwide take them every day as prophylactics against AIDS...all because we discovered how our bodies work!

With all of our efforts toward alternative energy sources, such as solar and wind power, it’s only natural that we would combine them. Wind turbines are a great way to harvest wind energy and convert it into usable energy; however, they can be large, bulky, and hard to maintain. What if you could integrate windmills with solar panels? Wind-driven turbines could be connected to photovoltaic cells that would track movement to maximize their effectiveness.


Hydrogen and ethanol are two biofuels that are well on their way to replacing fossil fuels as a source of electricity and transportation fuel. Hydrogen is produced by splitting water molecules, while ethanol is made by fermenting grains like corn. Ethanol could be particularly useful because it can be burned in current vehicles without modification. The government will have a strong role in developing these technologies—the European Union recently announced plans to help fund dozens of research projects devoted to developing hydrogen fuel cells—but there are also business opportunities here, especially if you’re willing to take risks on emerging technologies.


Computer technology is one of humankind’s greatest inventions. The idea of a machine that can perform complex calculations by relying on binary code, data storage, and processing power has spawned countless advances in everything from health care to home entertainment. As computer technology continues to advance at a rapid pace, it will become even more prevalent in our lives—and sometimes it may feel like we have no choice but to keep up with it all. Still, computers are machines built for humans and they can only accomplish what we design them to do. Designing computers that fit well into your daily life is an important step toward implementing advanced technologies thoughtfully and skillfully so they bring us closer to creating a better world for everyone.

Auto Filters

Automated spam filters may be used by email servers to decide whether or not your message is spam and then choose to block, quarantine, or allow your email. They are often based on sophisticated statistical algorithms that examine features such as a message's content (including words and phrases) and also its metadata (e.g., time of arrival, the sender IP address). These types of programs can make mistakes, however, resulting in false positives: messages erroneously blocked as spam; similarly, legitimate emails falsely identified as spam. There are many examples of these kinds of errors over recent years: a more amusing example being an issue with Yahoo! Mail in which certain large online photo albums were marked as 'spam' due to containing images with random characters in their titles.

Drone Flying


Remote-controlled planes, or drones, have many practical applications. They’re great for filming and can often get to areas that are too dangerous or impossible for a human. For example, delivering medical supplies to remote locations or taking photos of a crime scene to gather police evidence. The Federal Aviation Administration is currently working on regulations that will make it easier for everyday people to use drones; as early as 2015, hobbyists could apply for permission to fly them in certain cities. The Air Force also announced plans in 2012 to test drone deliveries of pizzas and drinks in rural Virginia communities beginning in 2013. Imagine an army of drones bringing you your next meal!
