TV shows like CSI give viewers a glimpse of how investigators solve crimes using DNA and other forensic tools, all wrapped up in an hour. What these shows skip over is important: the evolution of DNA technology. DNA completely changed the way law enforcement investigates crime. Now we can prove beyond any doubt whose DNA was left at a crime scene. Highly sensitive technology allows us to develop forensic DNA profiles from vanishingly small samples. A national and international network of DNA databases results in "cold hits" that link previously unknown perpetrators to cases, exonerate the innocent and bring justice to victims.
During the Russian Revolution of 1917, Czar Nicholas and his family disappeared. In 1920, a mysterious woman surfaced in Germany claiming to be his youngest daughter, the Grand Duchess Anastasia Romanov. In this presentation, Amanda McBrien will talk about this transformative time in Russian history while illustrating how modern science, through the use of forensic evidence and DNA comparisons, helped solve the mystery of what really happened to Anastasia.
In this presentation, physicist Nadya Mason, neuroscientist Kay Tye, and TED's science curator David Biello will talk about the highs and lows of giving a TED Talk — and the importance of communicating the wonder of science in all media. Come learn how to make your research accessible and exciting to the general public without alienating your scientific peers, including do's and don'ts for public speaking. In a world where the facts of science are newly up for debate, science communication has never been more critical.
Brady Haran will talk about his adventures in making science and math videos on YouTube. Referencing specific examples, he will illustrate how popular and perhaps unconventional communication can sometimes yield surprising results. These examples include recent breakthroughs in the summing of cubed numbers.
Human emissions of greenhouse gases now overwhelm the influence of natural drivers in altering Earth's climate. How will our energy choices and resulting emissions affect temperature and precipitation, extreme events, sea-level rise and more over this century and beyond? What are the implications for meeting the targets of the Paris climate agreement and avoiding dangerous change? And what about the potential for surprise, as we push the climate system harder and faster than any other time in human history? Join Katharine Hayhoe as she highlights key results and new science from the U.S.’s Fourth National Climate Assessment and lays out how climate change is affecting regions and sectors across the country. With climate change being one of the most hotly debated scientific issues of today, Hayhoe will also discuss the key role our values play in shaping our attitudes and actions on this crucial topic.
Join astrophysicist Paul Sutter on a virtual tour of the solar system from the safety of your own home, exploring each of the planets in our cosmic neighborhood. This event is meant for the whole family and focuses on middle and high school state science standards. Sutter will also point out constellations you can see from your own backyard. Bring your curious questions because, after the tour, Sutter will stick around for an expert Q&A and trivia game.
In this webinar, Laura Kahn will provide a comprehensive overview of COVID-19 from three different perspectives: issues around emerging diseases spread from animals to humans; our country’s public health response during the outbreak; and the household-level response that everyone should undertake to respond to the pandemic.
