  While modern technology has helped astronomers view the furthest reaches of the Solar System, it has also allowed scientists to start discovering planets orbiting distant stars. To make it easier to assess the relative mass and size of the new planets being discovered, scientists give these measurements as multiples of those properties for either Jupiter or Earth. In other words, if the planet is the same mass as Jupiter, then this measure would be listed as 1.0 MJ. If it were three times the mass of Earth, then it would be listed as 3.0 MEarth. The sizes of exoplanets are frequently given by expressing their radii as multiples of Jupiter’s radius or as multiples of Earth’s radius, RJ and REarth, respectively.  
  	Of course, given the immense distances involved, detecting exoplanets has always been hard, even to this day. The variations of light that might be evidence of an exoplanet can be caused by other phenomena, and separating the false positives from the actual detections is part of the rigor required by modern planet hunters. For example, in July 1988, a Canadian team led by astronomers Bruce Campbell, Gordon Walker, and Stephenson Yang discovered persistent indications that a planet orbited the primary star in the Gamma Cephei system, 44.98 light-years (13.79 parsecs) from the Earth. Though the technique they used was successfully employed in many subsequent discoveries, the quality of their data was insufficient for others to verify as unequivocally the result of an extrasolar planet. For reasons of poor data quality, the claimed discovery of Gamma Cephei Ab was retracted in 1992.  
  	The first confirmed discovery of an exoplanet involved a system that surprised most planet hunters. While most astronomers had been looking to find planets orbiting stars in the main sequence (between infancy and old age) or in their old age (giant phase), the first confirmed planets were found to orbit a dead star.

  Marie Salomea Skodowska Curie was a Polish-born, naturalized-French researcher and chemist who originated radioactivity research. She was the first woman to win the Nobel Prize, the first and only woman to win it two times, and the only individual to win the Nobel Prize in 2 different clinical classifications. 
  Her first Nobel Prize was co-won by her spouse, Pierre Curie, making them the first married set to win the reward and developing the Curie family tradition of 5 Nobel Prizes. She was the first woman to be selected as a teacher at the University of Paris in 1906. 
  Let’s take a look at what else she accomplished in her life.

  America was built on white pine. From the 1600s through the Civil War and beyond, it was used to build the nation's ships and houses, barns, and bridges. Yet this popularity came at a cost: by the end of the nineteenth century, clear cutting had decimated much of America's white pine forests. In White Pine, ecologist and writer John Pastor takes listeners on walk through history, connecting the white pine forests that remain today to a legacy of destruction and renewal. 
   
   
   
  Since the clear-cutting era, naturalists, foresters, and scientists have taken up the quest to restore the great white pine forests. White Pine follows this centuries-long endeavor, illuminating how the efforts shaped Americans' understanding of key scientific ideas, from forest succession to the importance of fire. Pastor shows us why restoring the vitality of these forests has not been simple: a host of other creatures depend on white pine and white pine depends on them. In weaving together cultural and natural history, White Pine celebrates the way humans are connected to the forest—and to the larger natural world. 
   
   
   
  Today, white pine forests have begun to recover, but face the growing threat of climate change. White Pine shows us that hope for healthy forests lies in understanding the lessons of history, so that iconic species survives.

  This audiobook is narrated by an AI Voice. In 2023, the Pacific Crest Trail was swallowed by the deepest snowpack in history. Most hikers waited for a better year. Riley laced his boots, hoisted his pack, and walked north. Snowbound is the story of one hiker’s path through 2,650 miles of relentless winter and the even harder terrain within. Battling exhaustion, river crossings, and weeks of silence, Riley confronted not just the weight of snow—but the weight of his past. Each step north was a letting go: of the version of himself shaped by fear, shame, and stories he no longer wanted to believe. From a near fall on Mt. Baden-Powell to the haunting stillness of Forester Pass, from the agony of loneliness to the quiet beauty of Leavenworth, this is a story of reckoning, resolve, and rising again. It’s not just a trail memoir. It’s a story about coming home to yourself—in the most unforgiving year on record.

  Plastics: Just a Load of...

  A decade to save the planet. 
  That's the current call to arms. Targets are set, governments vow to do their bit and on a societal level we are encouraged to do ours by choosing to forego all things plastic. The question is whether this is the right decision or are we inadvertently at risk of doing more harm than good? Are there other factors in play needing equal consideration? 
  The book will follow the story of plastic, and to an extent rubber (known collectively as polymers), and all with an eye to the overarching theme of the environment. It will ask some challenging questions but also sets out to inform. It begins by building a picture. Just what exactly is a plastic, how did it gain such a dominant role in our lives? Are recent denouncements fully justified? 
  By better understanding plastics, a clearer opinion can be formed of their usefulness and their potential to alleviate serious environmental concerns.
