...V) polarisations. In Alternating Polarisation (AP) mode it transmits in the same way, but can receive back radar pulses in both H and V polarisations. Combinations of HH/VV HH/HV or VV/VH polarisation pairs are possible. Depending on the physical and chemical properties of the surface, the responses from...

Robots walk with close-to-human efficiency

...It's not exactly the same thing, but certainly the mode of thought comes from thinking about robots," he says. Information gained from studying walking robots should be of use to the rehabilitation community, he adds. The researchers note in their Science paper that gravity-powered walkers have been con...

Topical treatment shown to inhibit HIV and herpes simplex virus infection

...h Organization, unprotected sex is the predominant mode of HIV transmission, and genital herpes plays a major role in the sexual spread of HIV. The researchers conducted a prospective, randomized, double blind, placebo-controlled study among 20 HIV-infected women to assess the antiviral activity of PRO...

Celebrex provides a two pronged attack against prostate cancer

...ese studies suggest that celecoxib exerts a second mode of action independent of its known anti-inflammatory mechanism that imposes further restrictions on the proliferation of prostate cancer cells. The results provide potentially important insights into our understanding of the overall anti-tumor activi...

Although researchers worldwide are investigating RNAi as a promising novel approach to gene therapy, TRC's primary focus is on developing RNAi as a biomedic...

Harvard, Texas A&M scientists develop new laser

...Instead, we use an internal electronic oscillation mode that can be designed or tailored over a broad range by changing the layer thickness of the constituent materials. This makes the device far more flexible and allows us to use it in room temperature conditions. We can design it to emit in the mid-infr...

'Second messenger' NAADP shows fast, dose-related impact on satiety cycle

Results of a new study "establishes NAADP as a new second messenger, and the study of this novel molecule has potential to extend its clinical significance, possibly as a candidate for ...

Immune system's initial response to cancer under study

...d amazingly, wily cancer cells can go into defense mode and avoid producing proteins recognizable to the immune system. "Tumor cells that survive and make the tumor are those that are least recognized by the immune system," says Dr. Kraj. "It's like natural selection: the fittest survive. Basically, the i...
