How do we know what’s real? That’s not a trick question: sensory science is increasingly finding that we don’t perceive reality: we create it through perception. In We Have the Technology, science writer Kara Platoni guides us through the latest developments in the science of sensory perception.
We Have the Technology introduces us to researchers who are changing the way we experience the world, whether creating scents that stimulate the memories of Alzheimer’s patients, constructing virtual limbs that approximate a sense of touch, or building augmented reality labs that prepare soldiers for the battlefield. These diverse investigations not only explain previously elusive aspects of human experience, but offer tantalizing glimpses into a future when we can expand, control, and enhance our senses as never before.
A fascinating tour of human capability and scientific ingenuity, We Have the Technology offers essential insights into the nature and possibilities of human experience.

The captivating, all-but-forgotten story of Isaac Newton, Albert Einstein, and the search for a planet that never existed
For more than fifty years, the world’s top scientists searched for the “missing” planet Vulcan, whose existence was mandated by Isaac Newton’s theories of gravity. Countless hours were spent on the hunt for the elusive orb, and some of the era’s most skilled astronomers even claimed to have found it.
There was just one problem: It was never there.
In The Hunt for Vulcan, Thomas Levenson follows the visionary scientists who inhabit the story of the phantom planet, starting with Isaac Newton, who in 1687 provided an explanation for all matter in motion throughout the universe, leading to Urbain-Jean-Joseph Le Verrier, who almost two centuries later built on Newton’s theories and discovered Neptune, becoming the most famous scientist in the world. Le Verrier attempted to surpass that triumph by predicting the existence of yet another planet in our solar system, Vulcan.
It took Albert Einstein to discern that the mystery of the missing planet was a problem not of measurements or math but of Newton’s theory of gravity itself. Einstein’s general theory of relativity proved that Vulcan did not and could not exist, and that the search for it had merely been a quirk of operating under the wrong set of assumptions about the universe. Levenson tells the previously untold tale of how the “discovery” of Vulcan in the nineteenth century set the stage for Einstein’s monumental breakthrough, the greatest individual intellectual achievement of the twentieth century.
A dramatic human story of an epic quest, The Hunt for Vulcan offers insight into how science really advances (as opposed to the way we’re taught about it in school) and how the best work of the greatest scientists reveals an artist’s sensibility. Opening a new window onto our world, Levenson illuminates some of our most iconic ideas as he recounts one of the strangest episodes in the history of science.
Stem Cell Dialogues: A Philosophical and Scientific Inquiry Into Medical Frontiers [EPUB]

"Stem cells" have become linked with both new frontiers in medical science and political and ethical controversy. The field, along with the emerging area of regenerative medicine, is creating the conditions for a time when damaged tissue and organs might be repaired through personalized cell therapy as easily as the body repairs itself, therefore revolutionizing the treatment of numerous diseases. Yet to obtain human embryonic stem cells, scientists must destroy human embryos – a prospect that has provoked intense reactions among the American public.
Addressing the moral and ethical issues of stem cell research while also educating readers about the biological function and medical applications of these cells, this book features fictional characters engaging in compelling inquiry and debate. Participants investigate the scientific, political, and socio-ethical dimensions of stem cell science using actual language, analysis, and arguments taken from scientific, philosophical, and popular literature.
Each dialogue centers on a specific, recognizable topic, such as the policies implemented by the George W. Bush administration restricting the use of embryonic stem cells; the potential role of stem cells in personalized medicine; the ethics of cloning; and the sale of eggs and embryos. Additionally, speakers debate the use of stem cells to treat paralysis, diabetes, stroke effects, macular degeneration, and cancer.
Educational, entertaining, and rigorously researched (with 300 references to scientific literature), Stem Cell Dialogues should be included in any effort to help the public understand the science, ethics, and policy concerns of this promising field.
