Feeding tomato juice to mice kept them from developing emphysema after cigarette smoke exposure that was long enough to induce emphysema in a control group, Japanese researchers report in February issue of the American Journal of Physiology-Lung Cellular and Molecular Physiology.
Scientists have developed a new technique for crystallising proteins, a discovery which could help speed up the development of new medicines and treatments.
Newer football helmet technology and design may reduce the incidence of concussions in high school football players, according to results from the first phase of a three-year study by the University of Pittsburgh Medical Center’s (UPMC) Sports Medicine Concussion Program. The current study compared concussion rates and recovery times of high school athletes wearing newer helmet technology to those wearing helmets with traditional designs. There was no significant difference in recovery time between the two helmet groups.
Nine out of ten men fitted with a penile prosthesis were able to have sexual intercourse and eight out of ten were satisfied with the overall results, according to research published in the latest issue of BJU International. The researchers, from St Peter’s Hospital and The Institute of Urology in London, studied 447 men who had received 504 implants over a 25-year period. Subjects ranged from 21 to 78 with an average age of 52 and were monitored for an average of just over four years.
Sunflowers can produce a substance which prevents the AIDS pathogen HIV from reproducing, at least in cell cultures. This is the result of research carried out by scientists at the University of Bonn in cooperation with the Caesar Research Centre. For several years now the hopes for a completely new group of AIDS drugs have been pinned to what is known as ‘DCQA’. However, the substance is only available in very small quantities and is thus extremely expensive. By using the Bonn method it could probably be produced for a fraction of the costs.
A study out of Denmark on the effects of fish oil on the blood chemistry of diabetics found that fish oil supplements increased the amount of “good” cholesterol and decreased the amount of fatty substances in their blood:

Exposure to certain viral infections shortly before and after birth (the perinatal period) is associated with cerebral palsy, finds a study published online by the BMJ today. These findings support the theory that infections during this period can trigger brain damage and the development of cerebral palsy.
A new study done in the area burned in the catastrophic Biscuit Fire in southwestern Oregon in 2002 found that allowing trees to naturally regenerate works about as well or better than logging and replanting, and that undisturbed areas may be at lower fire risk in the future.
Astronomers have found clear indications that clumps of dark matter are the nursing grounds for new born galaxies about twelve billion light years away. A single nest of dark matter can nurture several young galaxies. These results from researchers at the Space Telescope Science Institute, the National Astronomical Observatory of Japan, and the University of Tokyo confirm predictions of the currently dominant theory of cosmology known as the Cold Dark Matter model.
Scientists using NASA’s Rossi X-ray Timing Explorer have found a doomed star orbiting what appears to be a medium-sized black hole – a theorized “in-between” category of black hole that has eluded confirmation and frustrated scientists for more than a decade.
