Physicist Zvonimir Dogic and his lab are on a roll. Last week, Dogic’s research was featured in two of science’s most respected journals, Science and Nature.

Imagine a balloon that could float without using any lighter-than-air gas. Instead, it could simply have all of its air sucked out while maintaining its filled shape. Such a vacuum balloon, which could help ease the world's current shortage of helium, can only be made if a new material existed that was strong enough to sustain the pressure generated by forcing out all that air while still being lightweight and flexible.

Carnegie Mellon University professor Keith Cook has received a four-year, $2.4 million grant from the National Institutes of Health (NIH) to support research and development of artificial lungs that patients may use long term in the comfort of their own homes while waiting for a lung transplant. Cook, an associate professor in the Department of Biomedical Engineering, will lead the project and collaborate with researchers from the University of Washington, Columbia University and Allegheny General Hospital in Pittsburgh.

A new class of synthetic platelet-like particles could augment natural blood clotting for the emergency treatment of traumatic injuries – and potentially offer doctors a new option for curbing surgical bleeding and addressing certain blood clotting disorders without the need for transfusions of natural platelets.

Astronomers searching the atmospheres of alien worlds for gases that might be produced by life can't rely on the detection of just one type, such as oxygen, ozone, or methane, because in some cases these gases can be produced non-biologically, according to extensive simulations by researchers in the NASA Astrobiology Institute’s Virtual Planetary Laboratory.

Scientists’ underwater cameras got a boost this summer from the Electron Microscopy Center at the U.S. Department of Energy’s Argonne National Laboratory. Along with colleagues at the University of Manchester, researchers captured the world’s first real-time images and simultaneous chemical analysis of nanostructures while “underwater,” or in solution.
