Here is a story that can save you money. It might even save your life. If we could see all of the organisms that surround us, we would see microbes, billions of them, many kinds of viruses, bacteria, fungi and archaea. Most of them do nothing to us. Some could help us. Others, if they […]
A new study has revealed how infection with measles exposes children to many other causes of death. This is something caring parents need to know about. Measles (aka rubeola) shows up as a rash. It is very infectious. Because it mostly just goes away we tend to think of it as a nuisance that keeps […]
Climate change is no longer a forecast. It’s news. And even if we all stopped burning fossil fuels tomorrow climate change would go on getting worse. We see a range of consequences, like historically severe droughts. How does this affect us? The UN International Decade for Action on water ends this year. Its webpage says: […]
Skepticism’s healthy. These days we don’t have to believe a news story. But to get the benefits of skepticism we need to check stories out. A good-news story in a past Science Seen post has a simple message: Hot water can cure the common cold. Some who read the post or social-media re-posts were skeptical. […]
You likely do not often think about how you are put together on a microscopic scale. You are a conspiracy of cells. Roughly a hundred trillion of them, each one more or less autonomous. Each shapes its environment (you) by talking to co-conspirators. Cells do this instinctively. Their ancestors survived by doing it for millions […]
These days there’s news about the pros and cons of vaccinations. There is good news and there’s bad news. Let’s unscramble them, because we can learn from both good and bad. There is good news about ebola vaccines. Ebola is about eight times less infectious than measles but it’s far more deadly. It’s a gruesome […]
Around the world we’re starting to see same-old knee-jerk stuff. Irrational reactions to Ebola hurt us all: World Health Organization Director-General Margaret Chan says that 90 per cent of economic costs of an epidemic ‘come from irrational and disorganized efforts of the public to avoid infection.’ ‘Public’ includes public officials and push-button politicians and panicky […]
Ebola is a scary virus. Most know it is deadly. It is an international problem. We need evidence-based action to solve it, not play-on-fear border closings (c.f., SARS and swine flu) that do no good but damage the economy. We need a public conversation on ebola and it might be aided by some terms you […]
Last week we looked at how adopting smart sun habits―tan, but never burn―minimizes your risk of many cancers and of other serious diseases. Now let’s take a closer look at physics that is triggered when you catch some rays, because there’s something else that you may want to do. A solar UVB photon has enough […]
