25 Interesting Topics to Research

Today there are many interesting topics to investigate broadly, in fact, there is so much knowledge out there today that it would be literally impossible to read all the books, research, videos, and other content formats out there. However, not everything is discovered, there is still much to know.

The first thing you should do when you are going to research or write about a topic is to think about a subject, a subject or even a current news item that you are passionate about. The process of searching for information and writing is much easier when the content fascinates you.

The appearance of new diseases or conditions without a definitive cure, the search for inexhaustible resources or the desire of the human being throughout time to be immortal have marked the most interesting topics to investigate.

There are also issues related to national or global politics, or economic organization, on which it is necessary to find new answers and solutions that contribute to harmony and social cohesion.

If you want to dedicate yourself to documentary research or you have to carry out a project or work and you don’t know what topic to do it, I bring you some ideas on subjects that may be of interest to you and about which there is still a lot to know.

List of topics of interest to investigate

the coronavirus

At the end of the year 2019, a pandemic arrived that spread throughout the world; that of the coronavirus. The main consequence was the death of thousands of people, although it has also affected the way of working, studying and the economy around the world.

Private trips to space

Companies like Space X or Blue Origin, owned by Elon Musk and Jeff Bezos respectively, have begun to successfully launch rockets into space. It is a new space race, but this time privately.

Bitcoin and cryptocurrencies

Cryptocurrencies, crypto assets or cryptocurrencies are a digital form of exchange or digital currency made from cryptography. Although there are hundreds of them, the most widespread is Bitcoin.

electric cars

Electric cars have begun to replace gasoline cars, in fact in places like the European Union they have begun to tax diesel cars. It is an important issue, since it is one of the keys to reducing greenhouse gases.


China has had a very large economic growth in recent years, in addition to growing in its military power. It is expected to replace the United States as the world’s leading power.


One of the savage destroyers of the environment. Scientific evidence suggests that its reduction is necessary if we want to keep the Earth in a healthy state. Therefore, studying its causes, consequences and possible solutions is an obligation for researchers.


Nanotechnology has been at an unstoppable pace since the last decade, a stage in which notable use is already being made of it. However, very little is still known about its full potential.

Dedicating time to research this science could lead to improvements in human well-being, but also risks such as possible environmental destruction or uses for terrorist or weapons purposes.


Cancer is one of the most worrying diseases today, due to the number of people it affects and its high mortality rates.

The main studies related to this ailment have to do with examinations and the way to detect it early in patients, since it is one of the guarantees so that it has a better chance of survival.

Of course, research continues into the causes, which in recent studies have been closely linked to a poor diet and lifestyle.


Genetics studies how certain biological factors are transmitted from generation to generation. The fundamental objective of this science is to completely decipher the sequence of information carried by DNA.

This acid is considered the individual’s instruction book or manual. If it is possible to understand 100%, it would be possible to fully understand the functioning of the human being.

This is another interesting topic to investigate, because knowing what each of the DNA sequences means can help prevent hereditary diseases, correct the predisposition of some individuals to suffer from it.

Assisted reproduction

Life habits, which increasingly delay maternity and the genetic problems that some couples have to have children, have contributed to an exponential increase in the number of pregnancies through assisted reproductive techniques.

It is estimated that almost 50 million couples have infertility problems worldwide. In addition, according to the Spanish Fertility Society (SEF), Spain leads the European ranking in assisted reproduction treatments. Therefore, it follows that this field of research is in full development.

Investigating on this topic can help discover new assisted reproductive techniques, improve their protocols and contribute to the happiness of many couples with difficulties who are wanting to have their own child.

Artificial intelligence

This field of study refers to the creation of systems and equipment by humans and that have intelligence designed for certain tasks or objectives.

Currently, most artificial intelligence devices are related to everyday tasks such as searching for information, calling someone on the phone or getting to a place. For example, SIRI on Iphone or a GPS.

The interest in making the lives of human beings easier and gaining time for other tasks has led to the rise of this area of ​​research. There are still many everyday tasks that could be made much easier with artificial intelligence, so go for it!


If before we talked about the possibilities of artificial intelligence, surely you are much more passionate about human intelligence, due to the infinite questions that still remain unanswered.

The brain is the most complex organ in the human body, so much remains to be discovered and explored about its mechanisms. These studies can help counteract the damage caused by some injuries in your functioning or know what activities stimulate or decrease your activity.

If you dare to delve into the study of the brain, it may be good for you to know these 50 interesting curiosities about the human brain.

Alternative energies

In recent decades, the search for alternative energy to burning fossil fuels such as coal, gas and oil has gained great importance.

This recent interest is due to the great environmental deterioration that planet Earth has suffered with the emissions of carbon dioxide into the atmosphere and the consequent global warming, among other things caused by the use of these traditional energies. Also, to the finite resource that these fuels represent.

In this sense, studies on environmentally friendly energy sources and whether they can be inexhaustible such as solar or wind energy have gained special relevance.

For some experts, it is also considered alternative energy to nuclear energy. In relation to this there is also much to explore, especially in terms of security measures to avoid catastrophes such as Chernobyl or Fukushima.

Climate change

In addition to the search for alternative energy sources, there are other measures that can be taken in the industrialization process or in everyday life, for example recycling, to avoid climate change.

It is up to you to discover the best methods to prevent climate change and, above all, to combat it, since it seems that much of the damage to the planet is now irreversible.


The Great Recession that began in 2008 and continues to affect the world has brought a lot of work to economists. The approaches and responses when facing this crisis continue to be disparate, so your point of view may also have a place and become the definitive solution.

Another interesting topic would be the search for improvements to implement the current economic system, capitalism, and make it fairer for everyone, combining its operation with a true Welfare State and a fair distribution of resources.

This last point makes a lot of sense today, when the economic inequality gap has widened even more with the crisis.

World poverty

As I have commented in the previous point, the gap between rich and poor has become even greater with the economic recession. The Intermón Oxfam report “Extreme inequality” from 2014 warned about how the income of the rich minority in the countries of the world was increasing, while the poor were getting poorer.

Giving answers to world poverty is a problem that has been going on for a long time and is very difficult to solve due to the large economic interests against it.

Making the population aware of this problem through statistics, field studies and seeking solutions to eradicate world poverty leads to infinite research work.


This is another factor closely related to world poverty. If you are really interested in social issues, researching the causes of war conflicts, the interests at stake and the search for solutions is a good way to invest your time studying.

With the analysis of the wars that have taken place throughout history, you will be able to find out what the objectives and strategies of the great world powers are, as well as look for alternative security measures to the arms race of the States.

It is difficult to achieve changes in this area of ​​study, but if challenges and social causes are your thing, it is yours without a doubt.

Food and nutrition

The increase in obesity rates in countries like the United States (28.8 body mass index) and high malnutrition in many developing states have contributed to the growth of this area of ​​study.

Understanding the differences between food and nutrition is essential to make society aware of a good habit when sitting at the table.

The field of food and nutrition is very broad, so there is a lot to investigate, since habits that are considered healthy today may be refuted tomorrow by better ones.

Drug use and abuse

This field of research is also relatively recent. It was in the year 1930 when scientists began to study addictions and their associated behaviors. Thanks to these studies, the damage that drugs produced in the brain was discovered.

According to the National Institute of Drug Abuse, scientific research is essential to achieve the well-being of different nations.

The study may be oriented to the effects on the brain produced by these substances, to the social factors that influence a future drug addiction, if there is any genetic predisposition to suffer a…
