According to Otani, "This has enabled us to devise novel methods which may be effective in eliminating undesirable co...Carnegie Mellon University chemists create versatile polymer brushes
...y macro- or micro-scale synthetic hybrid materials combining organic and inorganic compounds are strong, but they break under stress. By creating these nano-scale molecular hybrids using ATRP, the Matyjaszewski lab has created extremely durable materials that won't crack. These materials could work well as a c...Researchers discover strategy that shields HIV from destruction
... said. Better yet, Shaw said, may be the idea of combining an immunogen that elicits neutralizing antibodies with other components of the human immune system, including cytotoxic T-lymphocytes. In the course of their work, Shaw and his colleagues developed a new strategy for detecting HIV-1 antibodies that...Diamond film may enable critical new sensors for bioterror
... is getting the needed chemical stability and then combining that with electronic sensing," says Robert J. Hamers, a professor of chemistry at UW-Madison. Hamers worked in collaboration with Lloyd Smith, also a UW-Madison professor of chemistry, to develop the chemistry for the new diamond surfaces, and with D...Can't stand the pain? Your genes may be to blame
...emotions and feelings, of healthy volunteers. By combining genetic testing with molecular brain imaging techniques and controlled, sustained jaw pain, the researchers were able to see how well the participants' brains controlled the pain, and how they felt as a result, depending on what forms of COMT they ca...Backstage with a command performer

Many possible combinations during this process allow a wide catalog of antibodies to literally take shape. Now, a biochemical phenomenon involving changes to stationary proteins in the B ce...New life discovered in deep ocean floor

In addition to Kawaoka, members of the group publishing the report in today's PNAS include: Yutaka Fujii of Hiroshima University, the University of Tokyo and the UW-Madison School of Veterinary Medicine; Hid...Researchers achieve germline transmission of 'gene knockdown' in mice
...ese and other features of the strategy, as well as combining it with drug discovery and other methods, should enable scientists to uncover a great deal of information about how genes influence many normal and pathological processes. Although the current study targeted a gene thought to be involved in DNA repai...Eye's light-detection system revealed

...ores, so Carter sought to enhance the technique by combining pressure with powerful cycles of ultrasonic energy. Though he obtained a patent for that approach in 1997, it still was unable to kill the toughest of microbes. Undaunted, he approached Georgia Tech for help.

...nesce as well. Next they created mixed colonies by combining the different strains in pairs: wild type and 22 hour; wild type and 30 hour; 22 hour and 30 hour. Then they put these mixed cultures into incubators with three different light-dark cycles 22 hours, 24 hours and 30 hours and monitored them for abo...Combining key ingredients of vegetarian diet cuts cholesterol significantly, says study
A diet combining a handful of known cholesterol-lowering plant components cut bad cholesterol by close to 30 per cent in a study by researchers at U of T and St. Michael's Hospital. The reduction is similar to that achieved by some drug treatments for high cholestero...Brain's method of creating mental images differs with the source of cues received
... the brain is taking in different sensory cues and combining them to create one representation, then there could be an infinite number of combinations that the brain is perceiving to be the same," said Banks. "The brain perceives a block to be three inches tall, but was it because the eyes saw something that l...Three inferior prefrontal regions of the brain found receptive to somatosensory stimuli

Interestingly, all antibodies have the ability to do this, which leads the TSRI team to speculate that the removal of singlet oxygen may have been the original role of ant......tion was observed. The researchers also found that combining aspirin with a monoclonal antibody specific for the HER-2/neu protein created even greater suppression of growth than treating the tumor cells with aspirin alone.
