Our understanding of astrophysics states that we should be seeing co-orbiting planets when astronomers look through their telescopes. Co-orbiting planets are planets of roughly similar size that have overlapping orbits around their host star. These two planets orbit so closely to each other that they influence the orbital paths and speeds of one another. When […]
Cancer is one of the greatest challenges of our time. A common misconception about cancer is that it is one disease. There are hundreds of unique types of cancers that all require different treatment strategies. This diversity in cancer types is one reason curing cancer is so difficult. The advances in medicine over the last […]
Ecosystem A biological community of living things interacting with one another and their physical surroundings.
You are on one of those trips where the travel is so tedious that even your cell phone looks boring. Not being able to sleep, you look out the window to distract yourself. You see lots of plants, people along the road, birds disappearing in the distance, and you just can’t stop wondering — how […]
Animals are unable to tell us why they do the things they do, and curious scientists often want to find out. They set up experiments to see how animals behave in certain situations and try to determine the motivations for the behavior. The behavior often gives the animal a survival edge, as is the case […]
Model In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations. – Read More @ […]
Molecule A group of atoms covalently (permanently, can’t be broken without using energy) bonded together to create a totally new substance with it’s own unique physical and chemical properties. It is different from a mixture, where the components are not covalently bonded together.
Species a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g., Homo sapiens. Credit: Google
Nitrogen pollution is a big problem in standing water such as lakes and ponds. The nitrogen comes from many sources, often agricultural fertilizers. Some of this nitrogen is in the water, but the rest of it is actually trapped in the sediment at the bottom of the lake. You can see evidence of this pollution […]
51 Pegasi b is a roughly jupiter-sized planet around a star pretty similar to our sun. This planet has been part of astronomy conversations before, as it is a huge planet with a really small orbit; this planet orbits around its star only every 4 days. For comparison, Earth orbits the sun every 365 days. […]
Nucleus The center of the cell, bound by a membrane that contains and protects the DNA.
Theory A scientific idea supported by such a large body of evidence over a long period of time that it is unlikely to be overturned.
At the center of the Milky Way Galaxy, there is a supermassive black hole. This is normal — at the center of almost every galaxy there is a black hole that is millions or billions times heavier than our sun. As galaxies move through the universe, they occasionally collide (the Milky Way is currently colliding […]
When we first learn about cells in biology, we are taught that bacterial cells are simple, and animal and plant cells are more complex. Mammalian cells, the cells that make up dogs, humans and all mammals, are “eukaryotes.” Eukaryotes have multiple membranes — one surrounding their innermost section, the nucleus, which protects their DNA and […]
