In theory, wireless networks can transfer only a limited amount of information. However, researchers have now shown how the limits of conventional W-LAN networks can be significantly overcome. It is a battle with the boundaries of physics: ever since information transmission theory was developed, it has been known that only a limited amount of data can be transferred by wireless communication within a defined frequency band.

HIV-positive women in the United States face strikingly high levels of stigma, according to new survey results. The results reveal pervasive negative views of HIV-positive women and a high level of discomfort in interacting with them. Many of the responses display a lack of knowledge of how HIV is transmitted and misplaced fear of contracting the virus that indicate a pressing need to increase prevention education efforts.

Each human nose encounters hundreds of thousands of scents in its daily travels perched front and center on our face. Some of these smells are nearly identical, so how do we learn to tell the critical ones apart? Something bad has to happen. Then the nose becomes a very quick learner. New research shows a single negative experience linked to an odor rapidly teaches us to discriminate that odor from similar ones.

The vast majority of Scottish people interviewed in the streets of Edinburgh are unaware of one of the greatest achievements of medical science — the eradication of smallpox from the world over 40 years ago. A recent poll has revealed that 87% of 200 individuals questioned did not know that the horrendous, killer disease is now extinct.

A new finding may account for why the flu virus is more infectious in cold winter temperatures than during the warmer months. At winter temperatures, the virus’s outer covering, or envelope, hardens to a rubbery gel that could shield the virus as it passes from person to person, the researchers have found. At warmer temperatures, however, the protective gel melts to a liquid phase. But this liquid phase apparently isn’t tough enough to protect the virus against the elements, and so the virus loses its ability to spread from person to person.
