Out of the gait: Robot ranger sets untethered 'walking' record at 14.3 miles (July 23, 2010) -- The loneliness of the long-distance robot: A robot named Ranger walked 14.3 miles in about 11 hours, setting an unofficial world record. A human -- armed with nothing more than a standard remote control for toys -- steered the untethered robot. ... > full story

Cancer-metabolism link runs deep in humans, novel network algorithm suggests (July 23, 2010) -- Eighty years ago, the medical establishment believed cancer was caused by a dysfunction of metabolism, but the idea went out of vogue. Now, scientists are again looking at metabolism and its role in cancer and other common diseases. ... > full story

Supercomputer reproduces a cyclone's birth, may boost forecasting (July 23, 2010) -- Scientists have employed NASA's Pleiades supercomputer and atmospheric data to simulate tropical cyclone Nargis -- with the first model to replicate the formation of the tropical cyclone five days in advance. ... > full story

How do cells die? Biophotonic tools reveal real-time dynamics in living color (July 23, 2010) -- Apoptosis, programmed cell death, is essential to normal development, healthy immune system function, and cancer prevention. The process dramatically transforms cellular structures but the limitations of conventional microscopy methods have kept much about this structural reorganization a mystery. ... > full story

Nanoparticles as destructive beacons to zap tumors (July 23, 2010) -- A group of researchers is developing a way to treat cancer by using lasers to light up tiny nanoparticles and destroy tumors with the ensuing heat. ... > full story

New technique for studying dark energy (July 23, 2010) -- A new but technically challenging observational "shortcut" will help make large-scale cosmic maps that can yield clues to to the nature of the mysterious "dark energy" that pervades the universe. ... > full story

New quantum state of matter discovered in Heusler compounds: Applications in spintronics, quantum computing and new physical effects (July 23, 2010) -- Scientists have been researching Heusler compounds, which are an important material class for the use in spintronic applications. Over the past few years, new application areas have emerged in the field of renewable energy, such as solar energy and thermoelectrics. And now Heusler compounds are also being considered for future technologies such as quantum computers. ... > full story

Transparency through open notes: Risks and rewards of inviting patients to review their medical records (July 23, 2010) -- Technology has placed vast amounts of medical information literally a mouse click away. Yet what often may be central -- a doctor's notes about a patient visit -- has traditionally not been part of the discussion. In effect, such records have long been out of bounds. In a new article, researchers speculate about the risks and rewards of making clinicians' notes transparent to patients. ... > full story

Can chaos theory help predict heart attacks? (July 23, 2010) -- Chaos models may someday help model cardiac arrhythmias -- abnormal electrical rhythms of the heart, say researchers. ... > full story

European Space Agency develops radar to watch for space hazards (July 23, 2010) -- As part of the European Space Agency's Space Situational Awareness activities, a new radar system will be developed to help safeguard space missions. The radar will detect hazardous objects in Earth orbit and trigger warnings that enable satellite operators to avoid collisions, making spaceflight safer for all. ... > full story

NASA telescope finds elusive buckyballs in space for first time (July 23, 2010) -- Astronomers using NASA's Spitzer Space Telescope have discovered carbon molecules, known as "buckyballs," in space for the first time. Buckyballs are soccer-ball-shaped molecules that were first observed in a laboratory 25 years ago. ... > full story

Math model of colon inflammation singles out dangerous immune cells (July 23, 2010) -- Scientists have constructed a mathematical and computational model of inflammatory bowel disease that allows researchers to simulate the cellular and molecular changes underlying chronic inflammation in humans. The model allows scientists to explore different interactions of cells in the immune system, check how these cells are linked to inflammation in the colon, and identify intervention points to perhaps stop the disease in its tracks. ... > full story
