Eating probiotics regularly may modestly improve your blood pressure, according to a new review of none studies examining blood pressure and probiotic consumption in 543 adults with normal and elevated blood pressure.

Probiotics are live microorganisms naturally occurring bacteria in the gut thought to have beneficial effects; they have recently been a nutrition trend and common sources are yogurt or dietary supplements. 

Researchers have helped identify over 100 locations in the human genome associated with the risk of developing schizophrenia, in what is the largest genomic study published on any psychiatric disorder to date. The findings point to biological mechanisms and pathways that may underlie schizophrenia, and could lead to new approaches to treating the disorder, which hasn't made much scientific progress in the last 60 years. 

Age-related macular degeneration (AMD) is the most common cause of visual impairment and blindness in industrialized countries but it is questionable whether it can continue to be defined as a disease in people in their 50s and beyond.

Investigations to determine the incidence of age-related macular degeneration undertaken as part of the Gutenberg Health Study of the University Medical Center of Johannes Gutenberg University Mainz (JGU) have shown that even persons under the age of 50 years may be affected by an early form of the eye disease.

Just under 4 percent of the 35 to 44-year-old subjects in the population-based study were found to be suffering from AMD. 

Models for the evolution of life are now being developed to try and clarify the long term dynamics of an evolving system of species. Specifically, a recent model proposed by Petri Kärenlampi from the University of Eastern Finland in Joensuu accounts for species interactions with various degrees of symmetry, connectivity, and species abundance. This is an improvement on previous, simpler models, which apply random fitness levels to species.

The findings demonstrate that the resulting replicator ecosystems do not appear to be a self-organized critical model, unlike the so-called Bak Sneppen model, a reference in the field. The reasons for this discrepancy are not yet known.

Scientists have developed a scalable, next-generation platelet bioreactor to generate fully functional human platelets in vitro. 

A new discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees but instead 'dance' in orderly disc-shaped orbits is a challenge to our understanding of how the universe formed and evolved.   

The universe contains billions of galaxies. Some, such as the Milky Way, are immense, containing hundreds of billions of stars. Most galaxies, however, are dwarfs, much smaller and with only a few billion stars.

For decades astronomers have used computer models to predict how these dwarf galaxies should orbit large galaxies. They had always found that they should be scattered randomly.
