  The Silent Universe - How Dark...

  Dark energy represents one of the most perplexing and enigmatic components of our universe, fundamentally altering our understanding of cosmic evolution. This mysterious force, which constitutes a major part of the cosmos, has intrigued scientists, astronomers, and physicists for decades. Its discovery, in part by observing the accelerated expansion of the universe, challenged long-held beliefs that gravity would eventually decelerate the cosmic expansion after the Big Bang. The revelation that the universe is not slowing down but actually speeding up has led to an explosion of theories and debates regarding the true nature of dark energy. 
  The initial hints of dark energy arose from studies that observed distant supernovae and measured their redshifts. When these measurements indicated that galaxies were moving away from each other at accelerating speeds, researchers were forced to rethink the previously accepted model of a decelerating universe. This unexpected acceleration suggested that some form of energy, previously unknown, was counteracting the force of gravity on a cosmic scale. Scientists have since begun to consider the possibility that this energy is uniformly spread throughout space, rather than being concentrated in specific locations, an idea that fundamentally differs from classical forms of matter and energy. 
  One of the core puzzles in understanding dark energy lies in its apparent uniformity and pervasive influence. Unlike ordinary matter, which clumps together to form stars, planets, and galaxies, dark energy seems to work in a diffuse, omnipresent manner, influencing the fabric of space itself. Its effects are subtle and counterintuitive, pushing galaxies apart rather than drawing them together.

  The Elements of Marie Curie -...

  The acclaimed Pulitzer Prize finalist and #1 New York Times bestselling author of Galileo’s Daughter crafts a luminous chronicle of the most famous woman in the history of science, and the untold story of the remarkable young women trained in her laboratory 
   
  “Even now, nearly a century after her death, Marie Curie remains the only female scientist most people can name,” writes Dava Sobel at the opening of her shining portrait of the sole Nobel laureate decorated in two separate fields of science—Physics in 1903 with her husband, Pierre, and Chemistry by herself in 1911. And yet, as brilliant and creative as she was in the laboratory, Marie Curie was equally memorable outside it. Grieving Pierre’s untimely death in 1906, she took his place as professor of physics at the Sorbonne, devotedly raised two brilliant daughters, drove a van she outfitted with X-ray equipment to the front lines of World War I, befriended Albert Einstein and other luminaries of twentieth-century physics, won support from two US presidents, and inspired generations of young women to pursue science as a way of life.  
   
  As Sobel did so masterfully in her portrait of Galileo through the prism of his daughter, she approaches Marie Curie from a unique angle, narrating her remarkable life of discovery and fame alongside the women who became her legacy—from France’s Marguerite Perey, who discovered the element francium, and Norway’s Ellen Gleditsch, to Mme. Curie’s elder daughter, Irène, winner of the 1935 Nobel Prize in Chemistry. For decades the only woman in the room at international scientific gatherings that probed new theories about the interior of the atom, Marie Curie traveled far and wide, despite constant illness, to share the secrets of radioactivity, a term she coined. Her two triumphant tours of the United States won her admirers for her modesty even as she was mobbed at every stop; her daughters, in Ève’s later recollection, “discovered all at once what the retiring woman with whom they had always lived meant to the world.” 
   
  With the consummate skill that made bestsellers of Longitude and Galileo’s Daughter, and the appreciation for women in science at the heart of The Glass Universe, Dava Sobel has authored a radiant biography and a masterpiece of storytelling, illuminating the life and enduring influence of one of the most consequential figures of our time.

  When Nashville identified its first case of coronavirus in March 2020, the city was between Public Health Department directors and as unprepared as the rest of the world for what was to come. Dr. Alex Jahangir, a trauma surgeon acting at that time as chair of the Metro Nashville Board of Health, unexpectedly found himself head of the city's COVID-19 Task Force and responsible for leading it through uncharted waters. 
   
   
   
  What followed was a year of unprecedented challenge and scrutiny. Jahangir, who immigrated to the United States from Iran at age six, grew up in Nashville. He thought he knew the city well. But the pandemic laid bare ethnic, racial, and cultural tensions that daily threatened to derail what should have been a collective effort to keep residents healthy and safe. 
   
   
   
  Hot Spot is Jahangir's narrative of the first year of COVID, derived from his op notes (the journal-like entries surgeons often keep following operations) and expanded to include his personal reflections and a glimpse into the inner sanctums of city and state governance in crisis.

  Nephrology - Kidney Health...

  The kidneys are two bean-shaped organs located on either side of the spine, just below the ribcage. Despite their small size, each roughly the size of a fist, they play a vital role in maintaining overall health. As part of the urinary system, the kidneys filter waste, balance bodily fluids, regulate blood pressure, and contribute to red blood cell production. Understanding how the kidneys function is crucial for appreciating their importance and recognizing potential health concerns. 
  Each kidney contains about a million tiny filtering units called nephrons. These nephrons work tirelessly to remove waste products and excess fluids from the blood, which are then excreted as urine. The kidneys also help maintain the body’s electrolyte balance by regulating levels of sodium, potassium, and calcium. This precise balance is essential for proper nerve and muscle function. Additionally, the kidneys produce hormones such as erythropoietin, which stimulates red blood cell production in the bone marrow, and renin, which helps regulate blood pressure. Without the kidneys' ability to perform these tasks, the body would struggle to maintain equilibrium, leading to serious health complications. 
  One of the kidneys' primary functions is detoxification. Every day, they filter around 50 gallons of blood, removing harmful substances such as urea, creatinine, and toxins that accumulate from food, medications, and metabolic processes. This filtration process ensures that waste products do not build up to dangerous levels in the bloodstream. When kidney function declines, these substances can accumulate, leading to symptoms like fatigue, swelling, and confusion.

  Marooned in LA by the pandemic, a marine biologist rediscovers the delights and wonders of the natural world in her own backyard. 
   
   
   
  Conservationist and marine biologist Maddalena Bearzi made her career studying the wild creatures of the deep, but when COVID-19 made landfall on the California coast this seafaring scientist found herself shuttered up ashore, her wide blue world constricted by pandemic lockdown. Never good at sitting idle, she despaired at the confines of her Los Angeles flat—until she began to find wonder in the wilderness of her own backyard. 
   
   
   
  Stranded charts Bearzi's discovery of both rapture and resilience in the unsung wildlife of urban LA. With a green thumb and a canine sidekick, she finds as much to marvel at in her garden's singing blackbirds, night-blooming cacti, and industrious wasps as in the whales, dolphins, and sea lions at the center of her maritime adventures. Discovering in the quotidian an antidote to the grief occasioned by captivity and climate chaos, Bearzi reveals how each of us can take heart, find courage, and discover inspiration in the thrumming systems of life that surround us. With a scientist's precision and a poet's instinct, she invites us to look at, listen to, and revel in the everyday grandeur of the natural world—and to embrace, with urgency, our responsibility to sustain it.
