'Virtual autopsy' helps identify drowning as cause of death

...the body. In addition, MDCT virtual autopsy may be useful as a pre-autopsy triage tool in mass casualty scenarios. "More and more, advanced imaging tools such as MDCT are being applied to forensic investigations," Dr. Levy said. "In the future, imaging in forensics may be just as important as imaging in ...

How brain pacemakers erase diseased messages

...l implants, Grill said. That could be particularly useful for zeroing in on effective settings for implants used to treat diseases, such as epilepsy, in which seizures occur only sporadically, as well as conditions, such as depression, in which symptoms can vary widely from day to day. "In the case of tr...

NASA-funded robotic sub finds bottom of world's deepest sinkhole

...PTHX tested technologies and methods that might be useful in other underwater explorations, including the long-term possibility of exploring the oceans hidden under the icy crust of Europa, one of Jupiter’s moons. For the near term, NASA recently approved a project that will use these technologies to explor...

Smallpox outbreak: How long would it take for vaccines to protect people? Would it work?

...wever, provides benefits post-exposure, and may be useful in further preventing the spread of the disease. "If there were a release of the smallpox virus, we would vaccinate people immediately after the release," Frey said. "We'd move in and vaccinate people to prevent the spread." Frey said this res...

Catching cancer's spread by watching hemoglobin

...lood vessels just below skin growths would be very useful for distinguishing between malignant and benign skin tumors, and would remove the critical need for skin biopsies, which is especially helpful if there are multiple suspicious areas that need to be investigated. Since hemoglobin is highly concentr...

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

UCLA AIDS Institute researchers find a peptide that encourages HIV infection

...d that can enhance gene delivery, you would have a useful tool." Retrocyclin-1 (RC-100) is a circular peptide that has been shown in previous studies to inhibit the infection of CD4 cells with HIV. RC-111 is also cyclic and has the same amino acid sequence as retrocyclin-1. In both peptides, the amino a...
