#Our World in Data

Our recent publications We published a new topic page on Research and Development Research and development underpin nearly all of the transformative changes we see on Our World in Data. Cures for diseases, vaccines, and techniques to prevent infection have helped us survive beyond childhood and live much longer lives. Understanding hygiene, water, and sanitation has saved countless lives from preventable diseases. Electricity, artificial light, transport, and other energy technologies have transformed our lives. Agricultural research has broken deadlocks in crop yields and allowed us to produce enough food for eight billion people. Even beyond the long list of technological advances, research into effective political and economic systems, human rights, and social sciences have reshaped societies worldwide. More research is needed to address our largest problems — old and new. We will need innovations in clean energy to tackle climate change, in agriculture to feed a growing population, and in medical research to tackle existing diseases and prevent new ones. Research is vital to address emerging risks such as artificial intelligence and nuclear weapons. On our page you can find all of our data, visualizations, and writing on research, development, and innovation. How are mental illnesses defined? How do researchers study the prevalence of mental illnesses? Global data on mental health is essential to understand and support people with mental illness. This data can help us understand the scale and patterns of these illnesses, and how to reduce them. In two new articles, we dig into global data on mental health and where it comes from. First, we look at how mental illnesses are defined and diagnosed. For example, about 1-in-6 people in the US say they’ve had a depressed mood for several days in the past two weeks. But having one or a few symptoms does not necessarily mean that someone can be diagnosed with depression. Instead, health professionals look at the combination, duration, and effect of symptoms that people report. Next, we look at how researchers study the prevalence of mental illnesses. How do they collect this data, and how reliable is it? We look into two broad sources of this data — diagnoses and surveys — and explain the strengths and limitations of each. We also explain how researchers use this data to make global estimates of the prevalence of mental illnesses, including for countries where data has not been collected. Explore our featured work Artificial intelligence is transforming our world — it is on all of us to make sure that it goes well Why should you care about the development of artificial intelligence? Think about what the alternative would look like. If you and the wider public do not get informed and engaged, then we leave it to a few entrepreneurs and engineers to decide how this technology will transform our world. That is the status quo. This small number of people at a few tech firms directly working on artificial intelligence (AI) do understand how extraordinarily powerful this technology is becoming. If the rest of society does not become engaged, then it will be this small elite who decides how this technology will change our lives. To help change this status quo, we address three questions in this article: Why is it hard to take the prospect of a world transformed by AI seriously? How can we imagine such a world? And what is at stake as this technology becomes more powerful? Why randomized controlled trials matter and the procedures that strengthen them We published a new topic page on Influenza Learning curves: What does it mean for a technology to follow Wright’s Law? The mission of Our World in Data is to make data and research on the world’s largest problems understandable and accessible.

#CHC da Santa Casa

#World Heart Federation

We are excited to announce that registration for the World Congress on Rheumatic Heart Disease is now open! This is a unique opportunity to join a global community of experts, researchers and advocates working to #EndRHD.   This Congress recognizes the importance of addressing rheumatic heart disease not only from a scientific perspective but also from a broader societal standpoint. It seeks to foster an inclusive environment where researchers, healthcare professionals, community leaders, and individuals affected by RHD can come together to share knowledge, exchange ideas, and explore innovative approaches to tackle this disease.   Register now to secure your spot and take advantage of the early bird discount! We offer discounted rates for students, NGO representatives, and individuals from middle- and low-income countries, to ensure everyone has the opportunity to be a part of this important event.

Aging Myelin: A New Perspective in Alzheimer’s Disease Progression

Neuroscience News Jun 2 Age-related degeneration of myelin, the insulating layer around nerve cells in the brain, actively promotes disease-related changes in Alzheimer's. Researchers examined mouse models of Alzheimer's with myelin defects, finding that these defects accelerated the formation of amyloid plaques, a characteristic sign of Alzheimer's.

In January, Joanna Thompson wrote for Quanta about how inflammation can cause a loss of synaptic connections in the brain and lead to mood disorders such as depression. Inflammation can cause many problems, but it also protects us from pathogens. In 2022, Steven Strogatz interviewed the immunology researcher Shruti Naik for The Joy of Why podcast about why inflammation is a dangerous necessity. Two-Armed Milky Way?

Sucralose Damages DNA, Linked to Leaky Gut: Study

A new study reveals health concerns about the sugar substitute sucralose so alarming that researchers said people should stop eating it and the government should regulate it more.

Sucralose is sold under the brand name Splenda and is also used as an ingredient in packaged foods and beverages.

The findings were published this week in the Journal of Toxicology and Environmental Health, Part B. The researchers conducted a series of laboratory experiments exposing human blood cells and gut tissue to sucralose-6-acetate. The findings build on previous research that linked sucralose to gut health problems./.../
