Researchers find color sensitive atomic switch in bacteria

...rogram bumps up against a membrane." Cell membrane surfaces and their exposed proteins are the most accessible targets to treat human tissue or destroy infectious microbes, he said. More than 60 percent of medications target membrane proteins on human cells and many antibiotics target membranes on pathogens....

Study reveals why eyes in some paintings seem to follow viewers

...e was viewed from, Todd said. "When observing real surfaces in the natural environment the visual information that specifies near and far points varies when we change viewing direction," he said. "When we observe a picture on the wall, on the other hand, the visual information that defines near and far points...

...ing. His ability to translate the play of light on surfaces into digital code has not only secured his status as an academic computer scientist, it has taken him on a red carpet ride, earning him credits on films such as Terminator 3 and Shrek 2. In February, he earned an Academy Award for Technical Achieveme...

First glimpse of DNA binding to viral enzyme

...at allows structural information on the contacting surfaces of biological molecules to be precisely mapped. These contact points are regions providing critical communication in the cell," Chance explained. "In this study the footprinting approach provided information on the DNA binding region of the adenoviru...

Disease diagnosis, drug development focus of UH prof's biochip research

...derstanding the fundamental principles of how hard surfaces affect softer biological components like proteins and DNA. DNA chips, a type of biochip, have DNA molecules attached to a high-tech chip surface and have applications in genetic screening, disease diagnosis and drug development. "The design of bi...

Protein fishing in America: The movie

...heory holds. The repeated weak slapping of protein surfaces against one-another is the critical first step in a chain of events that rule all subsequent cellular behavior. But this vital exchange between single molecules has defied direct observation because that line-flicking and message-passing happen rando...

Meteorites supplied Earth life with phosphorus

...howed that phosphorus became concentrated at metal surfaces that corroded in the early solar system. "This natural mechanism of phosphorus concentration in the presence of a known organic catalyst (such as iron-based metal) made me think that aqueous corrosion of meteoritic minerals could lead to the formati...

Researchers show how to assemble building blocks for nanotechnology

...nth. The results of the simulations showed that if surfaces of particles could be patterned with patches of molecules, they could make the particles assemble into different shapes. The trick, according to the researchers, is using patches that are strongly directional and attract and repel specific parts of o...

Sweet success in targeting sugar molecules to cells in living animals

Urban heat islands make cities greener

...ntrations of buildings, roads and other artificial surfaces retain heat, creating urban heat islands. Satellite data reveal that urban heat islands increase surface temperatures compared to rural surroundings. Using information from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument o...

'Search and destroy' protein turns tables on HIV

...d in some HIV-resistant people, in which the outer surfaces of their cells no longer offer footholds for the virus to attach and begin the process of infection." Here's how the APOBEC proteins are thought to work. When the core of an HIV particle enters a cell, it contains single-stranded RNA as its genetic m...

Biocompatibility assumes greater sig...

Medical implants work better when you rough them up, study finds

Photosynthetic microorganisms, mainly proteobacteria, were found to populate the surface whereas Actinobacteria was the dominate population on the interior where no photosynthetic organisms were detected. Additional tests on the inter...

Study suggests double punch could more efficiently kill viruses

...all pieces of viral protein presented on the pAPCs surfaces can be generated when the infected protein is made by pAPC. Alternately, the other pathway, known as cross-priming, involves transfer of some form of protein, previously thought to be peptides, to the pAPC where it can be presented to T cells. "Altho...

Innovative 'self healing' bandage to help diabetics
