Molecules are constantly in motion as a result of a cell's stored kinetic energy, which causes them to bump into each other and move in random new directions. Diffusion is the movement of molecules from an area of where there are many (high concentration) to an area where there are fewer (low concentration).
Read MoreInfluenza pandemics have occurred multiple times throughout history. The influenza pandemic of 1918 was particularly severe and resulted in the deaths of 50-100 million people worldwide, with 500,000-675,000 deaths in the U.S. alone.
Read MoreThe Novel Coronavirus virus, specifically known as 2019-nCov, is responsible for a flu-like respiratory illness and has already to spread to 75,728 people and resulted in the deaths of more than 2,128 worldwide. While the vast majority of those confirmed cases have been within China, countries around the world are on high alert as confirmed cases have been reported in at least 26 other countries.
Read MoreDoes the environment in which a bee was raised determine its aggressiveness?
Honey bees are highly social creatures that live in large colonies of about 40,000 individuals and one queen. Every member of the hive works together to benefit the colony. Some of the tasks adult bees perform include making honey, nursing young, foraging for food, building honeycomb structures, and defending the colony.
Read MoreWhen Charles Darwin talked about the “struggle for existence” he was making the observation that many individuals in the wild don’t survive long enough to reach adulthood. Many die before they have the chance to reproduce and pass on their genes to the next generation.
Read MoreData have the power to change the world. Today we have the tools to record data and uncover life-changing insights faster than ever. Let's go back in time when the only data tools available were pen and paper. That's all Florence Nightingale needed to change the world forever with her data.
Read MoreIn what ways does the abundance and/or sex ratio of male and female humpback whales change over the course of the year in the Western Antarctic Peninsula? People have hunted whales for over 5,000 years for their meat, oil, and blubber. In the 19th and 20th centuries, pressures on whales got even more intense as technology improved and the demand for whale products increased.
Read MoreHow do female juncos determine the quality of potential mates?
Animals collect information about each other and the rest of the world using multiple senses, including sight, sound, and smell. They use this information to decide what to eat, where to live, and who to pick as a mate. Choosing a mate is an important decision that requires a lot of information, such as how healthy a potential partner is, and information about their genes. Mate quality can affect how many offspring an animal has and if their genes will get passed on to the next generation.
Read MoreDo insects prefer local or foreign foods? Featured scientist: Elizabeth Schultheis from Michigan State University Research Background: Insects that feed on plants, called herbivores, can have big effects on how plants grow. Herbivory can change the size and shape of plants, the number of flowers and seeds, and even which plant species can survive in a habitat.
Read MoreWhen the tragedy of a mass shooting repeats itself in cities across the United States, we find ourselves asking why it happens. While gun violence is not a uniquely American problem, more mass shootings occur in the United States than in any other country on earth. And they keep happening. What can explain this? Data can provide insights into the underlying factors that may be responsible for gun violence in the United States.

Read MoreThis Ready-to-Teach dataset contains the number of Spotify streams of "All I Want For Christmas is You" by country on the 48 hours of Christmas Eve and Christmas Day as well as the song's country-specific mean rank among all songs over the holiday season.
Read MoreSince it can be difficult and time consuming to observe wild mammals, researchers use camera traps to record data on the populations of interest. Camera traps are motion-activated cameras that photograph any animal that passes in front of the camera. The photos are then reviewed to identify which species were captured on camera and how frequently they were recorded in the photos. These data can then be used to answer research questions about biodiversity in the surrounding area and inform the Maijuna’s conservation management plan.
Read More"The sight of a feather in a peacock's tail, whenever I gaze at it, makes me sick."
That is what Charles Darwin wrote when first thinking about the showy and elaborate tail feathers of the male peacock. If traits that aided in survival were selected for and were more likely to be passed on to the next generation, how was it that evolution by natural selection could produce something like the brightly colored and elaborate tail feathers of a peacock?
Read MoreIn 2015, over 381 million tonnes of plastic was produced globally. That is equivalent to the mass of two-thirds of the world population! Take a look around and see how many plastic items you can find. All of those water bottles, straws, and plastic grocery bags add up and their waste is making a large negative impact on our oceans and wildlife.
Read MoreIt is sometimes important to know how quickly a particular chemical reaction occurs. We can discern this information by measuring either the amount of reactant(s) consumed over time or the amount of product(s) produced over time.

Read MoreYour students can easily make the graph in seconds and spend their time thinking about which is the better measure of central tendency, mean or median, to describe the salary of an NBA player. You can use our discussion questions (included in the dataset description) or write your own.
Read MoreEach spring the cherry blossoms, “sakura” in Japanese, put on a natural spectacle that has been of major importance to Kyoto, Japan going back at least as far as the 9th Century. Since that time, records have been kept to document the “full flowering date” when the blossoms are at their peak on the cherry trees.
This has made for a very strong dataset to indirectly look at climate change and look for any effect on the timing of season. Explore this dataset to look for any patterns in the data that may reveal a change in the timing of spring in Kyoto, Japan.
