Mihir Garimella is a Google Science Fair winner, robotics enthusiast, and Pennsylvania high school student. His winning science project? Flybot, an autonomous flying robot whose design was inspired by the capabilities and behavior of the fruit fly. “I don’t even like fruit flies, I find them really annoying,” Garimella said at TEDxTeen earlier this year, “but they’re good at almost everything they do!”
The humble toilet — it may not seem like much, but modern toilets and sanitation engineering are to thank for myriad improvements in public health over the years. But approximately 2.5 billion people around the world still do not have access to proper sanitation, according to the UN. This leaves them vulnerable to contaminated drinking water and diarrheal disease, a major cause of death among children in the developing world.
Scientists estimate that by 2050, we will need to produce 50% more food than we do now to keep up with the earth’s growing population, with forces like climate change and natural resource depletion making this an even greater challenge. How will these changes impact the way people eat in the coming decades? Below, find five TEDx Talks from chefs, designers, and other innovators who are working to ensure the future of food security.
Maps help us keep track of the wealth of data in the world — whether showing how disease spreads to the best place to hail a cab. These six TEDx Talks tackle the layered process of mapmaking, and show how maps shape how we see the world.
After more than ten years in space and flybys of three different planets in our solar system, NASA's MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft will reach the end of its mission. Launched in 2004, the MESSENGER mission was created to study Mercury's chemical composition, geological structure and history, magnetic field, and other attributes.
Victims deserve better than to be reduced to objects for others’ consumption.
Conversations about Miyamoto’s reception in Japan need to focus on her blackness as much as they focus on her mixedness.
A recent scientific study has introduced the idea of music for cats' enjoyment. Housecats might get annoyed by music made for humans, but music that's made up of sounds tailor-made for their enjoyment might be a different story.
Pangolins (order Manis) are a group of species of mammal found in tropical Asia and Africa. They're instantly recognizable by their spiky scales, unusually long tongues, and ability to spray like skunks. Unfortunately, they are critically endangered due to illegal hunting and trading of their body parts.
Scientists who study behavior have long been interested in the differences between men and women. What are the differences in behavior between men and women? Why do these differences occur? Are they learned or innate? While many people have preconceived ideas about how people of different genders behave, recognizing and quantifying these differences scientifically can be tricky.
This Women's History Month, celebrate women in science through reading! Science Books & Films has even compiled a reading list for the occasion. Below, take a look at science books written by or about women with the accompanying Science NetLinks teaching resources.
Women's History Month, celebrated in March in the United States, is an annual celebration of women and their contributions to society. While women's accomplishments make the news all year long, these recent stories about women in science and the science of gender are worth a read:
You've never seen stars like this before!
The image above is an example of star trail photography. If you stare at the sky in the same direction over a period of time, the stars will appear to move across to sky relative to the Earth. This happens because the Earth rotates. The above picture shows this effect captured on camera.
National Park Week, an annual event in the United States, begins this weekend on April 18! To celebrate, the National Park Service is offering free admission for guests to all national parks during opening weekend, April 18-19. If you live near a national park, this is a great opportunity to get outdoors and explore geology, earth science, and ecosystem biology.
Quick, what year will it be after December 31? If you said 2015, you'd be right — but only according to the Gregorian calendar. While the Gregorian might be the most commonly used calendar internationally, it is only one of many currently used by different cultures around the world.
