Two presentations at the 27th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID) show that repeated infection with the bacterium Clostridium difficile (C. difficile), which causes stomach upsets and diarrhoea, is linked to higher death rates, as well as having a significant impact on health services in terms of cost and hospital beds occupied.
To examine the latest scientific evidence related to non-caloric sweeteners, focused on stevia, the Global Stevia Institute is hosting a sponsored symposium on Saturday, April 22 from Noon - 3:00 PM at the American Society for Nutrition (ASN) Scientific Sessions, taking place at the annual Experimental Biology conference in Chicago.
Confronting evidence that the global climate is changing rapidly relative to historical trends, researchers at North Carolina State University have developed a new statistical model that, when applied to the loblolly pine tree populations in the southeastern United States, will benefit forest landowners and the forest industry in future decades. The research, titled 'Optimal Seed Deployment Under Climate Change Using Spatial Models: Application to Loblolly Pine in the Southeastern US' appears in the Journal of The American Statistical Association.
A collaborative study between researchers at Massachusetts General Hospital and Boston University School of Medicine has found evidence implying that alcoholism may have different effects on the reward system in the brains of women than it does in men.
Traditional clinical hearing tests often fail to diagnose patients with a common form of inner ear damage that might otherwise be detected by more challenging behavioral tests, according to the findings of a University at Buffalo-led study published in the journal Frontiers in Neuroscience.
Colonization by the human and animal parasite, Giardia, changed the species composition of the mouse microbiome in a way that might be harmful. The research is published in Infection and Immunity, a journal of the American Society for Microbiology.

New research by scientists at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA overturns a long-standing paradigm about how axons grow during embryonic development. The findings of the study, led by Samantha Butler, associate professor of neurobiology, could help scientists replicate or control the way axons grow, which may be applicable for diseases that affect the nervous system, such as diabetes, as well as injuries that sever nerves.
A Swedish-led team of astronomers used the NASA/ESA Hubble Space Telescope to analyze the multiple images of a gravitationally lensed type Ia supernova for the first time. The four images of the exploding star will be used to measure the expansion of the Universe. This can be done without any theoretical assumptions about the cosmological model, giving further clues about how fast the Universe is really expanding. The results are published in the journal Science.
Our brains process foreign-accented speech with better real-time accuracy if we can identify the accent we hear, according to a team of neurolinguists.
Marine biologists James Hollibaugh and Sylvia Schaefer found that rising water temperatures could disrupt ocean food webs and lead to the release of more greenhouse gases.
New genetic evidence suggesting that early mammals had good night-time vision adds to fossil and behavioral studies indicating that early mammals were nocturnal.
During the first one and a half years of the Affordable Care Act (ACA), the number of prescriptions filled by adults using Medicaid coverage increased by 19 percent in states that expanded Medicaid compared to states that did not, according to a new study from a Harvard T.H. Chan School of Public Health researcher and colleagues. The largest increases were for medications to manage chronic conditions such as diabetes, and for birth control.
A good art dealer can really clean up in today's market, but not when some weird soap-making chemistry wreaks havoc on masterpieces. Since you have no time to watch paint dry, we explain how paintings from Rembrandts to O'Keefes are threatened by their own compositions -- and not just the imagery. Watch the latest Speaking of Chemistry video here: https://youtu.be/w2ww5aUJD8s.
New research suggests that excess sugar -- especially the fructose in sugary drinks -- might damage your brain. Researchers at Boston University found that people who drink sugary beverages frequently are more likely to have poorer memory, smaller overall brain volume, and a significantly smaller hippocampus. A follow-up study found that people who drank diet soda daily were almost three times as likely to develop stroke and dementia when compared to those who did not.
Scientists at the Centre for Genomic Regulation (CRG) in Barcelona and the Josep Carreras Leukaemia Research Institute and The Institute for Health Science Research Germans Trias i Pujol (IGTP) in Badalona, Spain, have discovered that the impact of environmental change can be passed on in the genes of tiny nematode worms for at least 14 generations -- the most that has ever been seen in animals. The findings will be published on Friday, April 21, in the journal Science.
Bacterial populations pose an intriguing puzzle: in so-called isogenic populations, all bacteria have the same genes, but they still behave differently, for example grow at different speeds. Researchers at the Institute of Science and Technology Austria (IST Austria) now solved a part of this puzzle by studying how the bacterium Escherichia coli divides up a protein complex that detoxifies cells by pumping multiple drugs such as antibiotics out of the cell.
An international research team led by Ariel Goobar at Stockholm University has detected for the first time multiple images from a gravitationally lensed Type Ia supernova. The new observations suggest promising new avenues for the study of the accelerated expansion of the universe, gravity and distribution of dark matter in the universe.
First 3-D quantum liquid crystals may have applications in quantum computing.
Men who have sex with men (MSM) accounted for two thirds of all new HIV infections in the United States, with 26 percent occurring in Latinos, according to 2014 data. If those rates continue, it is estimated that one in four Latino MSM may be diagnosed with HIV during his lifetime.
