"Written specifically for readers with little to no knowledge of the field, the articles within this collection cover everything from a basic overview of CRISPR technology and gene editing in GMOs to the ethical questions surrounding "designer babies" and other applications of biotechnology in humans"--

What do giant squids, mantis shrimp, and fireflies have in common? These animals, along with a wide range of creatures, are able to give off light; this is called bioluminescence. Different species use different chemistries to bioluminesce, and they produce their light for a variety of reasons, including communication, hunting, and self-defense. Bioluminescence is a unique and fascinating adaptation found in the animal kingdom. Surprisingly, about half of all known phyla (a classification for animals that share the same body type) contain some bioluminescent species. Scientists don't yet understand all facets of bioluminescence, but they have managed to harness the glow and use it in a myriad of ways. One of the most important applications involves using bioluminescence as a microscope in medical studies. For example, laboratory scientists can create fluorescent malaria parasites to track the path by which the disease is spread from a mosquito to the animal it bites. Bioluminescent proteins are also helping researchers learn more about cancer, HIV and other viruses, and complex neurological processes. In fact, bioluminescent proteins are so useful to twenty-first-century medicine that two groups of scientists, one in 2008 and the other in 2014, were awarded the Nobel Prize in Chemistry for their work with these proteins and related technologies. Even artists and fashion designers use bioluminescence in their work to create glowing, light-sensitive paintings and clothing lines. Author Marc Zimmer, a world-renowned specialist in fluorescent proteins, takes readers on a glowing journey into the frontiers of bioluminescence.

"Covering how science is done, why some people want to trick others, and why false information can be dangerous, this book empowers readers to know which sources to trust and which to dismiss as deceit"--

New research and innovations in the field of science are leading to life-changing and world-altering discoveries like never before. What does the horizon of science look like? Who are the scientists that are making it happen? And, how are we to introduce these revolutions to a society in which a segment of the population has become more and more skeptical of science? Climate change is the biggest challenge facing our nation, and scientists are working on renewable energy sources, meat alternatives, and carbon dioxide sequestration. At the same time, climate change deniers and the politicization of funding threaten their work. CRISPR, (Clustered Regularly Interspaced Short Palindromic Repeats) repurposes bacterial defense systems to edit genes, which can change the way we live, but also presents real ethical problems. Optogenetics will help neuroscientists map complicated neural circuitry deep inside the brain, shedding light on treating AlzheimerΓÇÖs and ParkinsonΓÇÖs disease. Zimmer also investigates phony science ranging from questionable ΓÇ£healthΓÇ¥ products to the fervent anti-vaccination movement. Zimmer introduces readers to the real people making these breakthroughs. Concluding with chapters on the rise of women in STEM fields, the importance of US immigration policies to science, and new, unorthodox ways of DIY science and crowdsource funding, The State of Science shows where science is, where it is heading, and the scientists who are at the forefront of progress.
