25 Jun. 2008Dark Matter/Alzheimer's-Memory Mice/Hany Farid/Wisdom of the Crowd
Dark Matter - Turns out most of the universe is held together by a mysterious, invisible substance. Of Mice and Memory - Mice placed in enriched environments can recover lost memories, giving hope to those who study Alzheimer's. Profile: Hany Farid - This self-proclaimed "accidental scientist" is a digital detective inventing new ways to tell if photos have been faked. Wisdom of the Crowds - Ask enough people to estimate something, and their combined guesses will get you surprisingly close to the right answer.
2 Jul. 2008Personal Genome/Digital Art Authentication/Capturing Carbon/Pardis Sabeti
Personal DNA Testing - Genetic testing to assess risk factors for a handful of serious illnesses is now commercially available. But is it a good idea? Art Authentication - See how clever computer algorithms can distinguish a master fake from a masterpiece. Capturing Carbon - An eighth-grader's science fair project prompts her scientist father to develop a new way to pull excess carbon dioxide out of the atmosphere. Profile: Pardis Sabeti - By night she's a rocker. By day, she's a Harvard geneticist tracking the evolution of the human genome.
9 Jul. 2008Hubble Repair/First Primate/Alfredo Quiñones Hinojosa/Iraqi Bacteria
Saving Hubble - Two teams of spacewalkers take on the risky mission of reviving the ailing Space Telescope. First Primates - Our most distant primate ancestors, which lived about 55 million years ago, were tree-dwellers the size of mice. Profile: Alfredo Quiñones-Hinojosa - He jumped the fence from Mexico to work as a farmhand and ended up a leading brain surgeon. Killer Microbe - A relatively benign bug becomes a highly lethal pathogen, known to U.S. soldiers as Iraqibacter.
23 Jul. 2008Leeches/The Search for ET/Stem Cells Breakthrough/Profile: Edith Widder
Leeches - A century after falling out of favor, medicinal leeches are back in hospitals, sucking away on patients' wounds. SETI - Astronomers have their radio telescopes tuned to receive signals from alien worlds. But is anybody out there? Stem Cells Breakthrough - Three separate teams overcome a biomedical hurdle-creating stem cells without the use of human embryos. Profile: Edith Widder - Meet a marine biologist and explorer who has engineered new ways to spy on deep-sea creatures.
30 Jul. 2008Phoenix Mars Mission/Brain Trauma/Mammoth Mystery/Judah Folkman Tribute
Phoenix Mars Lander - NASA's latest robot has already found frozen water and is looking for more signs that the Red Planet could support life. Brain Trauma - Even so-called "mild" head injuries turn out to be anything but. Mammoth Mystery - A pair of mammoth skeletons is found locked together by their tusks. What happened? Profile: Judah Folkman - Once scorned for his ideas about how cancer grows, the late Judah Folkman is now hailed as a visionary.
