We don't have to sit back and just watch the horror unfold

1 week ago | scientificdiscovery.dev | Saloni Dattani

This month, I signed a pledge to donate at least 10% of my lifetime income to effective charities. And this week, I decided to donate 19% of my annual income, with more than 80% to a charity working in Nigeria to complete a water and sanitation project. The project was being funded by USAID, but that funding was suddenly canceled by the Trump administration without notice. In recent months, US foreign aid programs have been slashed. It’s hard to wrap your head around the scale of these programs.
Links in Progress: Good drug news

We recently released Issue 18 of Works in Progress. Read about prehistoric psychopaths, fertility on demand and the king of fruits here. Today on Links in Progress Asimov Press’s Niko McCarty and our own Saloni Dattani return to review more important things happening in the world of biotechnology and medicine. 1. Nanopore sequencing is a promising, low-cost alternative to traditional genome sequencing methods. Nanopores are tiny holes in a membrane.
What share of births involve assisted reproductive technologies like IVF?

1 month ago | ourworldindata.org | Saloni Dattani

In 1978, Louise Brown became the first baby born through in vitro fertilization (IVF). In this technique, eggs are fertilized with sperm in a lab before the resulting embryos are transferred to the uterus. Assisted reproductive technologies have advanced further and now become widely available.
The baby boom in seven charts

1 month ago | ourworldindata.org | Saloni Dattani |Lucas Rodés-Guirao

The baby boom reshaped family life and drove population growth in many countries. In this article, we explore the key patterns in seven charts. The baby boom was a period that saw a surge in birth rates alongside a dramatic decline in death rates due to advances in medicine and public health. This combination led to rapid population growth in many high-income countries, which influenced their societies for generations.

Why the total fertility rate doesn’t necessarily tell us the number of births women eventually have

1 month ago | ourworldindata.org | Saloni Dattani |Lucas Rodés-Guirao

The total fertility rate is commonly confused with the eventual number of births per woman. This can result in misinterpreting the impact of policies and trends over time. When people talk about trends in fertility, they often use a single metric: the total fertility rate (TFR). It seems straightforward — after all, it’s often described as the average number of children per woman. But while TFR is a widely used metric, it’s not as simple as it sounds.
Cardiovascular disease death rates have fallen rapidly in many countries

Moving between continents is less common than moving to another country within the same region. For most people, international migration means crossing a nearby border, rather than a very long distance or even an ocean. Consider Asia, the world's most populous continent. When an Asian emigrant leaves their home country, they can either move to another Asian country or head to one of the other five continents.
Childhood cancer deaths in the United States have declined six-fold over the last seventy years

Record national life expectancies have been climbing for over a century. In 1840, Swedish women had a life expectancy of 46 years — the highest of any country recorded that year. By 1921, Australia held the record at 63 years. For most of the 20th century, Iceland, Norway, Australia, and Sweden competed for the top position before being overtaken by Japan in 1984. Hong Kong and Japan have held the records since then. These countries didn’t merely catch up; they’ve continued to push the limits higher.

Cholesterol levels have declined among American adults in recent decades

Dec 31, 2024 | ourworldindata.org | Saloni Dattani

High levels of cholesterol are a risk factor for atherosclerosis and cardiovascular diseases, which can lead to heart attacks and strokes. As the chart shows, the age-standardized share of American adults with unhealthy cholesterol levels has declined over the past 25 years. Age-standardized means the data accounts for the rising age of the population over time. Data comes from the National Health and Nutrition Examination Survey, a national study conducted every two years.
