Heartlight is the story of Bradley's greatest champion of good, Colin MacLaren, as he carries the banner of Light through the second half of the twentieth century. Ghostbuster, exorcist, student and teacher of the mystic arts, Colin meets Claire Moffat, who becomes his dearest friend, when he rescues her from a cult bent on human sacrifice. The leader of that cult, Toller Hasloch, becomes one of Colin's greatest enemies. Working behind the scenes for the next thirty years, Hasloch subtly manipulates politics and the economy to turn America away from the Light. Colin, busy saving lives and teaching the next generation of psychic warriors, realizes almost too late how Hasloch has warped America's promise.Now, Colin MacLaren is the only one who can face Hasloch and the hellhounds the younger man has unleashed. He must fight on, while the fate of America, and perhaps all mankind, hangs in the balance.At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

... across half a Galaxy, the Terran Empire maintains its sovereignty with the consent of the governed. It is a peaceful reign, held by compact and not by conquest. Again and again, when rebellion threatens the Terran Peace, the natives of the rebellious world have turned against their own people and sided with the men of Terra; not from fear, but from a sense of dedication. There has never been open war. The battle for these worlds is fought in the minds of a few men who stand between worlds; bound to one world by interest, loyalties, and allegiance; bound to the other by love. Such a world is Wolf. Such a man was Race Cargill of the Terran Secret Service.

By the time I got myself all the way awake I thought I was alone. I was lying on a leather couch in a bare white room with huge windows, alternate glass-brick and clear glass. Beyond the clear windows was a view of snow-peaked mountains which turned to pale shadows in the glass-brick. Habit and memory fitted names to all these; the bare office, the orange flare of the great sun, the names of the dimming mountains. But beyond a polished glass desk, a man sat watching me. And I had never seen the man before. He was chubby, and not young, and had ginger-colored eyebrows and a fringe of ginger-colored hair around the edges of a forehead which was otherwise quite pink and bald. He was wearing a white uniform coat, and the intertwined caduceus on the pocket and on the sleeve proclaimed him a member of the Medical Service attached to the Civilian HQ of the Terran Trade City. I didn't stop to make all these evaluations consciously, of course. They were just part of my world when I woke up and found it taking shape around me. The familiar mountains, the familiar sun, the strange man. But he spoke to me in a friendly way, as if it were an ordinary thing to find a perfect stranger sprawled out taking a siesta in here. "Could I trouble you to tell me your name?"

It was a week before the Lhari ship went into warp-drive, and all that time young Bart Steele had stayed in his cabin. He was so bored with his own company that the Mentorian medic was a welcome sight when he came to prepare him for cold-sleep. The Mentorian paused, needle in hand. "Do you wish to be wakened for the time we shall spend in each of the three star systems, sir? You can, of course, be given enough drug to keep you in cold-sleep until we reach your destination." Bart felt tempted-he wanted very much to see the other star systems. But he couldn't risk meeting other passengers. The needle went into his arm. In sudden panic, he realized he was helpless. The ship would touch down on three worlds, and on any of them the Lhari might have his description, or his alias! He could be taken off, unconscious, and might never wake up! He tried to move, to protest, but he couldn't. There was a freezing moment of intense cold and then nothing....

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.

What if neuroscientists could look inside the human brain and watch individual brain cells send signals to one another? What if they could then control these brain cells to direct thoughts and actions?This may sound like science fiction, but it's actually a scientific revolution called optogenetics. Neuroscientists would like to use this new technology on human brains to uncover secrets about how the brain processes information and drives human behavior. Doctors hope to use optogenetics to restore sight and to treat Alzheimer's disease, Parkinson's disease, depression, and other debilitating or deadly health problems. Discover how the innovative work of leaders in the field is poised to radically transform science, medicine, and human health.
