Can Dogs Help Diagnose Malaria?

Find out how dogs might be able to detect malaria.

Dogs have the potential to be helpful when it comes to detecting malaria. A study conducted by the Department of Biosciences at Durham University revealed that dogs might be able to be trained to smell the malaria parasite on humans.

Researchers at Durham University collected children's socks -- some of whom had malaria and others who did not. Researchers then brought in trained dogs to sniff the socks for the virus. Some dogs "were able to accurately detect 70% of infected children and 90% of uninfected children." However, further research in other countries is needed to ensure dogs can accurately sniff out the parasite.


This research is beneficial because training dogs to smell malaria is useful when it comes to people who have the disease but don't show common symptoms. Trained dogs will also be helpful in countries that are malaria-free: dogs can be positioned in airports to smell people coming in and out of countries with the parasite.

Exactly How to De-Escalate Aggression From a Stranger

Follow security Expert Bill Staton's important advice to keep yourself safe.

Have you ever had a tense interaction with a stranger in public? Perhaps your shopping carts accidentally knocked into each other or there was a misunderstanding in communication and the other person gets angry. You may wonder how you can de-escalate the aggression and exit the situation safely. So security expert Bill Stanton has your go-to advice for staying alert and protecting yourself in the face of verbal aggression and physical attacks.

THE INITIAL INTERACTION

Bill Stanton: "It always starts with something small, like someone being too close to you, or even more common, you get bumped by a shopping cart. You want to look at their eyes first -it may reveal emotional changes. But you can't rely on just that. Look at what their trunk is doing; a person's torso will reveal their intent. Body language like raising hands, heightened expression, tense shoulders — these are natural responses to a person who is feeling threatened and will escalate. They may begin to zero in on the space between you and them, and their voice will get louder and louder. You want to read this before it gets further and becomes explosive."
