NASA's Mars Science Laboratory is scheduled for a 2009 Earth launch. Two of the analytical devices selected for the mission are being designed by IU Bloomington geologists. They and their colleagues hope to learn more about the exact composition of Mars -- despite much information about the elements that exist there, humans know next to nothing about how those elements are organized in rocks.

Scientist at work: Richard DiMarchi
Diabetes affects nearly 21 million children and adults in the United States -- about 1 in 15 Americans. Part of living with diabetes is dealing with hypoglycemia, or low blood sugar, a problem that affects everyone who has diabetes at one time or another. Hypoglycemia can lead to dizziness, headache, sudden behavior changes, even seizures and loss of consciousness. In cases of severe hypoglycemia, glucagon, an injectable substance, raises blood sugar levels. Richard DiMarchi, chair of the Chemistry Department at IU Bloomington, is developing a glucagon-like drug into a product that can be administered quickly and simply via an injector pen to people experiencing diabetic shock.

The number of larger-aperture telescopes is growing, but size isn't all that matters in a research telescope. Also important is how much of the sky the telescope can clearly image. A telescope used by Indiana University astronomers and their colleagues at Kitt Peak National Observatory near Tucson, Ariz., is about midway through a major improvement -- the addition of a new kind of camera that will allow scientists to record the telescope's entire exceptionally wide field of view for the first time.

In hospitals today, the first warning that a post-operative patient is going into septic shock is often when the patient's blood pressure collapses and cardiac arrest begins. By that time the patient has a high probability of dying, or, if he survives, an even higher probability of permanent major organ damage after a long stay in an intensive care unit.

In the good old days, computer-savvy rogues used malware mainly to wreak havoc with others' computers. But cyber crooks now are stealing users' personal and financial information and defrauding businesses with more sophisticated attacks. Malware is increasingly targeting consumers. Markus Jakobsson, associate professor at the Indiana University School of Informatics, said that malware relies on social vulnerabilities to spread and infect. This makes it harder to detect and block malware because users bypass detection systems when they agree to use the software.

Why mitochondrial genes ditch their cushy haploid environs to take up residence in a large and chaotic nucleus has long stumped evolutionary biologists, but Indiana University Bloomington scientists report in this week's Science that they've uncovered an important clue in flowering plants.
