Glioblastoma is one of the most deadly brain cancers because it is nearly impossible to destroy the cause of the cancer: cancerous stem cells. However, scientists are using Zika’s preference for stem cells to target and eliminate the cancerous stem cells in adults. The preliminary study shows the viability of this method, but more thorough research and a PR campaign may be necessary before Zika treatments for brain cancer can become standard protocol. Continue reading Could Zika become a treatment for brain cancer?
3D printing is poised to become a major technological advancement in treating injuries and illnesses that cause tissue damage. For scientists, creating artificial tissue with 3D printing has been a challenge. As the 3D printed structure grows in size, cells often move and compromise the tissue’s structural integrity. New work from Oxford University addresses this problem. By encasing cells in nanoliter sized droplets of fat molecules, researchers are able … Continue reading Scientists Learn to 3D Print Cells One Drop at A Time
by Amir Bitran figures by Daniel Utter Proteins, the molecules that sustain all life, are similar to cars and other machines in an important way: they require a specific, well-defined structure to function. Obviously, a random pile of car parts cannot be driven. And similarly, a protein that is not assembled correctly cannot perform crucial tasks like producing energy, supporting cell structure, and generating electric signals. In … Continue reading The Hidden Genetic Code
What is the difference between a normal cell and a cancer cell? The answer lies in their DNA. Cancer results from the accumulation of genetic mutations, which trigger uncontrolled cell growth. Cancer’s mutated DNA can reveal its presence early on in the disease. Like leaving fingerprints at a crime scene, tumor cells release small pieces of DNA into the bloodstream. This “circulating tumor DNA” can now … Continue reading Catching Cancer: Blood Test for Early-Stage Diagnosis
by Chamith Fonseka figures by Rebecca Senft The concept of artificial intelligence (AI) tends to evoke images of self-aware computers and robots – Knight Rider, Wall-E, the Terminator – but for the most part, this technology is, for now, restricted to fiction and film. In that time, however, artificial intelligence has already become embedded in everyday life, playing a role in everything from online shopping … Continue reading Hold Artificial Intelligence Accountable
by Katherine Wu I don’t have many fond memories from middle school. The few bright spots that do exist in my memory, though, revolve around the three essential pillars: television, books, and AOL Instant Messenger. There were few things as satisfying as logging on to AIM and finding a Buddy List populated with the dorky screen names of dozens of my friends. Whether they were … Continue reading Dances with Chatbots: Interviews at the forefront of AI technology
by Harbing Lou figures by Shannon McArdel AI, the foundation of all video games If you have ever played a video game, you have interacted with artificial intelligence (AI). Regardless of whether you prefer race-car games like Need for Speed, strategy games like Civilization, or shooting games like Counter Strike, you will always find elements controlled by AI. AIs are often behind the characters you … Continue reading AI in Video Games: Toward a More Intelligent Game
