Few countries in the world are considered more vulnerable to the impact of rising sea levels and climate change than Bangladesh, a nation of 175 million people squeezed into a landmass the size of Iowa. In partnership with the Pulitzer Center, Fred de Sam Lazaro traveled to Bangladesh to look at efforts to build resilience in the face of the escalating consequences.

For a long time, scientists have suspected that stuttering — a common speech condition that affects an estimated 1 in every 100 people — could be heritable. Despite how common it is, it's still a remarkably understudied condition.
Geneticists Piper Below and Dillon Pruett were determined to fix that. With the help of 23andMe data, they recently identified 57 genetic regions linked to stuttering in the human genome. Their findings represent a new breakthrough in how researchers think about speech conditions, genetics and the conditions that are linked to them. They're what some are calling a "quantum leap" in the field.

Many Americans who want to get the newest COVID vaccines may now have a harder time doing so. The Food and Drug Administration limited approval for the shots to adults 65 and older or those who are "high risk" for severe disease. The vaccine was previously available to individuals six months of age and older. Amna Nawaz discussed the changes with Dr. Katelyn Jetelina of Your Local Epidemiologist.

As an anthropologist, Victor Buchli has one foot in the Neolithic past and another in the space-faring future. A professor of material culture at University College London, his research has taken him from excavations of the New Stone Age site at Çatalhöyük, Turkey to studies of the modern suburbs of London to examinations of life on -- and in service to -- the International Space Station.
It is in that later role, as principal investigator for a European Research Council-funded research project on the "Ethnography of an Extraterrestrial Society," that he visits the Social Science Bites podcast. He details for interviewer David Edmonds some of the things his team has learned from studying the teams -- both in space but more so those on Earth -- supporting the International Space Station.
Buchli describes, for example, the "overview effect." The occurs when which people seeing the Earth without the dotted lines and map coordinates that usually color their perceptions. "When you look down," he explains, "you don't see borders, you just see the earth in its totality, in a sense that produces a new kind of universalism."
He also reviews his own work on material culture, specifically examining how microgravity affects the creation of things. "It is the case within the social sciences, and particularly within anthropology, that gravity is just assumed. And so here we have an environment where suddenly this one single factor that controls absolutely everything that we do as humans on Earth is basically factored out. So how does that change our understanding of these human activities, these sorts of human institutions?"
More than 1 in 10 people in the United States take an antidepressant. And the most commonly prescribed type of antidepressant are SSRIs — or selective serotonin reuptake inhibitors. That includes drugs like Zoloft, Prozac and Lexapro. But what happens when some patients decide they want to stop taking their SSRIs? While doctors know stopping SSRIs can sometimes cause unpleasant short-term side effects – like dizziness, anxiety, insomnia and nausea – some people report symptoms that last months, even years. So, with investigative reporter Emily Corwin and professor of clinical psychology Michael Hengartner, we’re diving into the research around the long-term effects of going off your antidepressants – what it shows and its limits.

Trisomy 18, also known sometimes as Edwards syndrome, is often fatal within weeks after a baby is born. But now, parents and doctors are finding ways of getting more time with those children with greater interventions and incredible commitments. Stephanie Sy discussed the difficult ethical questions around it with Dr. Sheri Fink. PBS News is supported by - https://www.pbs.org/newshour/about/funders. Hosted on Acast. See acast.com/privacy
This year marks the 50th anniversary of "Jaws," the 1975 Steven Spielberg blockbuster about a ravenous great white shark. The film packed theaters and instilled a deep, lasting fear of sharks. While many Americans are terrified of them, shark attacks are relatively rare and the species is widely misunderstood. William Brangham discussed more with Keith Cowley of the Shark Research Institute. PBS News is supported by - https://www.pbs.org/newshour/about/funders. Hosted on Acast. See acast.com/privacy
Monday night football is back! What better way to celebrate than a close look at some of the physics powering the sport? Specifically, the spiral pass. If you've ever watched part of a professional football game, you've probably seen a tight spiral pass. They're those perfect throws where the football leaves the player's hand and neatly spins as it arcs through the air. Those passes can seem to defy fundamental physics — and for a long time, scientists couldn't figure out exactly why. That is, until experimental atomic physicist Tim Gay cracked the case within the last few years. His answer comes after two decades of hobby research and more than a couple late night shouting matches with two other physicists over Zoom. (encore)

What will remain of us hundreds of millions of years from now? And how can we be so certain that we are the first technologically advanced species on Earth?
These unsettling questions have been haunting listener Steve. If fossils can be lost to deep time through erosion and subduction into the Earth’s mantle, how would anyone — or anything — ever know that we had been here? And if an earlier species had built a civilization that rose and fell, would we even be able to find traces of it?
To investigate, CrowdScience presenter Caroline Steel speaks to the scientists trying to answer these questions, while producer Sam Baker goes fossil hunting on the Jurassic Coast in the UK.
Caroline speaks with astrophysicist Adam Frank at the University of Rochester in the US, who along with NASA scientist Gavin Schmidt developed the Silurian hypothesis – the idea that if an advanced species had existed deep in Earth’s past, they might have vanished without leaving a trace.
But palaeontologists Jan Zalasiewicz and Sarah Gabbott from the University of Leicester in the UK argue that humans are already leaving an indelible mark in the form the chemical and material fingerprints we’re pressing into Earth’s crust. They contend that the ‘technofossils’ we are producing will last a very long time indeed.
Along the way, Caroline and producer Sam discover just how rare fossils really are, how even the tiniest particles of pollution will give us away to far-future explorers, and why car parks might be our ultimate legacy. What they find is at once unsettling and oddly comforting: humanity could be fleeting, but our impact probably won’t be.
Could we really have missed evidence of an ancient civilization? And what strange clues will we leave behind for whoever, or whatever, comes next? We explore Earth’s geological memory to find out.
