Laugh Along At Home With The Ig Nobel Awards We know traditions are different this year. Maybe you’re having a small family dinner instead of a huge gathering. Maybe you’re just hopping on a video call instead of going over the river and through the woods. At Science Friday, our holiday tradition of broadcasting highlights from the annual Ig Nobel Awards ceremony is different this year too. Rather than being recorded live in front of a cheering crowd at Harvard’s Sanders Theater, the ceremony was

Exploring The Invisible Architecture Of Cities With Roman Mars On a walk through your city or town, there are all sorts of sights and sounds to take in—big buildings, parks and patches of green space, roaring vehicles, and people strolling around. But according to Roman Mars, host of the 99% Invisible podcast, you need to look at the smaller, often unseen details to decode what’s really going on in the city. In the new book The 99% Invisible City: A Field Guide to the Hidden World of Everyday

Puerto Rico's Famous Arecibo Observatory Decommissioned The astronomical observatory in Arecibo, Puerto Rico, has been standing since 1963. It has weathered hurricanes, earthquakes, and time itself. But in August, a large cable—holding up one of three towers that help suspend the telescope’s 900-ton receiver platform above the collecting dish—slipped out of its socket. It fell into the dish below, leaving a trail of broken panels. One broken cable seemed like a fixable problem, but in early

Our Average Body Temperature Is Getting Cooler We’ve all been getting our temperature checked on the regular these days. Most restaurants and businesses have been scanning peoples’ foreheads with thermometer guns to check for signs of fever as a safety precaution for COVID-19. We’ve been told that our temperature should be around 98.6 degrees Fahrenheit (or 37 degrees Celsius), the “normal” human body temperature. The value was set over 150 years ago by the German physician Carl Reinhold August

The New Biden Administration Plans For COVID-19 It’s been less than a week since it became clear that Joe Biden would be the president elect. While President Trump and his allies continue to push unsubstantiated claims of election misdeeds—with no evidence—the Biden transition team is moving into action. This week, as coronavirus cases spike alarmingly around the country, the president-elect unveiled his own coronavirus task force. The team of experts will help guide the incoming administration’s

What Will The Pandemic Look Like During The Winter? It’s been almost a year since officials in China announced the spread of a mysterious pneumonia, and identified the first COVID-19 patients. On January 21, the first U.S. COVID-19 case was confirmed in Washington State. And new record highs for cases were set this week. Since March, just about every country in the world has tried to get a handle on the pandemic using different interventions. Infectious disease expert Michael Osterholm and

How Algae Survived A Mass Extinction Sixty-six million years ago when an asteroid slammed into what is now the Yucatan peninsula, it set off a period of near global darkness for almost two years. Scientists think a majority of land species went extinct during that time, but what was going on in the planet’s oceans? And how were these ecosystems able to bounce back? In a new paper published in Science Advances, researchers say what saved Earth’s oceans may have been a type of algae that could hunt

Choosing the next U.S. president is not the only decision voters will make in the upcoming 2020 elections. Major science policies are also on the ballot. In some states, people will be casting votes on propositions that influence scientific research and the environment. While in other local elections, candidates with scientific backgrounds are in the running for public office.

The first “scientific” election poll was conducted in 1936 by George Gallup, who correctly predicted that Franklin D. Roosevelt would win the presidential election. Since Gallup, our appetite for polls and forecasts has only grown, but watching the needle too closely might have some unintended side effects. Solomon Messing, chief scientist at ACRONYM, a political digital strategy nonprofit, tells us about a study he co-authored that found people are often confused by what forecast numbers mean, and

Even In A Pandemic, Science Class Is In Session This academic year, school campuses across the United States look very different. Instead of crowded hallways and bustling classrooms, students are spaced six feet apart, sometimes behind plastic barriers, while others are at home on camera in a video call. Since some states do not weigh in on school operations, communities witnessed a myriad of learning approaches, such as fully virtual, fully in-person, or a mixture of both. All are subject to change

In rural Wyoming, there have been over 8,100 cases, with 57 deaths to date. More populated Wisconsin has seen over 167,000 cases—and recently crossed the grim threshold of 1,500 deaths due to the disease. Both states have reported more hospitalizations, with Wisconsin this week opening a field hospital to help deal with

The 2020 Nobel Prize winners have been announced, and among them is UCLA astronomer Andrea Ghez, who split the prize with Roger Penrose and Reinhard Genzel. Ghez, also the fourth woman to ever win the Physics prize, won for her 1998 work that resolved a decades-old debate among astronomers: What lurks at the difficult-to-observe heart of the Milky Way? After innovating new ways to peer through the obscuring gas and dust, Ghez and her team observed the orbits of stars around the galaxy’s seemingly

It’s here that Bill Tripp’s great-grandmother, who was born in the 1800s, taught him starting as a 4-year-old how to burn land on purpose. “She took me outside—she was over 100 years old—and walked up the hill with her walker,” Tripp recalled, “and handed me a box of stick matches and told me to burn a line from this point to that point.” Those cultural
