Mad dogs and Englishmen should stay out of the midday sun!

In a timely release, as much of Europe and Britain in particular sizzles through an unusually hot summer, a new report is warning against the dangers of exposure to the sun.

How much and what the eye tells the brain

Researchers at the University of Pennsylvania School of Medicine estimate that the human retina can transmit visual input at about the same rate as an Ethernet connection, one of the most common local area network systems used today.

Heat treatment may zap cancer cells

Scientists believe they have discovered a clue as to why so many men with testicular cancer survive against the odds.

Research findings may speed the development of vaccines for Chlamydia and other STDs

Using a novel mouse model that allows scientists to study how the immune system’s fighter cells respond to invaders in the genital tract during the initial stage of infection, researchers have found a way to track immunity against Chlamydia trachomatis.

New insights into how cells repair damaged DNA

Cancer researchers have discovered that a recently identified protein critical for repairing damaged genes uses an unusual mechanism to keep its repairs accurate.

Vaccination with irradiated Listeria induced protective T cell immunity

Vaccines made with bacteria killed by gamma irradiation, rather than by standard methods of heat or chemical inactivation, may be more effective, say researchers.

Using gamma radiation preserves T-cell responses in bacterial vaccine

Using gamma radiation to inactivate bacteria for the preparation of vaccines, instead of traditional heat or chemical methods of inactivation, appears to create a vaccine that is more effective than so-called "killed" vaccines against disease, and has the added advantage of a longer storage life than "live" vaccines.

HIV mutation clue to why only some people develop AIDS dementia

The study of 18 HIV-positive subjects shows that HIV in the brain and central nervous system is genetically different from HIV that lives in the blood and peripheral tissues.

Heat sensitivity may make testicular cancer cells more susceptible to standard treatments and die off more readily

Experts at Johns Hopkins have linked scientific evidence spanning more than 30 years to suggest an explanation for why testicular cancer patients like seven-time Tour de France winner Lance Armstrong survive far better than patients with other advanced cancers.

Irradiation preserves T-Cell responses in bacterial vaccine

Findings could result in more potent vaccines that are relatively inexpensive to produce, easy to store, and that can be transported without refrigeration.

How does the immune system isolate and destroy intruders?

Dendritic cells are the body's "watchdogs". They recognize and then degrade pathogens, isolating characteristic fragments that are recognized by the immune system thus triggering targeted responses.

Major genetic breakthrough in understanding of Wolbachia infection

Scientists have made a major breakthrough in understanding the genetics of the insect parasite that is being targeted by researchers as a way of preventing the spread of malaria.

Breakdown of disease caused by UV radiation

Ultraviolet radiation from the sun causes a considerable global disease burden, including specific cancers, a new World Health Organization (WHO) report finds.

Scientists identifiy the way MDM2 protein can trigger the spread of cancer

The protein, MDM2, normally functions to control the activity of a key cancer preventing protein called p53.

Birch bark compound may be potent prostate cancer fighter

A compound found in the bark of the white birch tree - betulonic acid, a derivative of betulinol - may finally have been rendered a water-soluble, bio-available drug, and is already showing the potential to be a possible agent against prostate cancer - in cell culture and in an animal model.
