Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
Evolution likes to borrow. It can take an already-successful biological structure and alter it until it serves a new function. Two independent groups studying the proteins that organize gut microvilli now suspect that this may have been the case in the development of inner ear hair cell stereocilia. While functionally very different, the protein complexes that organize microvilli and stereocilia have striking parallels. Both papers appear January 25 in Developmental Cell.
Children who participate in collaborative group work to learn about significant social issues become better decision-makers than their peers who learn the same curriculum through teacher-led discussions, a new study finds.
More than 760 fifth-grade students were involved in the study, which compared the efficacy of collaborative group work with conventional direct instruction at promoting students' ability to make reasoned decisions and apply those skills in a novel task.
In older adults, declining health is a major reason they stop driving. But when they stop driving, what impact does this have on their subsequent health and well-being?
A new review of published studies indicates that driving cessation in older adults may contribute to a variety of health problems, especially depression.
A high proportion of older adults entering long-term care homes in Ontario are B12 deficient, with more developing deficiencies over the course of their first year in residence, according to research from the University of Waterloo. There is a connection between B12 deficiency and several serious health conditions.
Researchers found that almost 14 per cent of study participants were B12 deficient at the time of admission to a long-term care home, while another 38 per cent had only slightly better levels. Over the course of one year, an additional four per cent developed B12 deficiencies. However, those receiving supplements had better B12 levels.
A new study in rats may provide significant insights into the long-term impacts of over-consumption of sugary foods during adolescence.
The study shows that the enjoyment of such foods later in adulthood is reduced in those who over-consumed early in life. Investigators found that this decrease in reward relates to reduced activity in one of the key hubs of the brain's reward circuitry, called the nucleus accumbens. Such long-lasting alterations could have important implications for reward-related disorders such as substance abuse or eating disorders.
LA JOLLA--(January 19, 2016) Agricultural grafting dates back nearly 3,000 years. By trial and error, people from ancient China to ancient Greece realized that joining a cut branch from one plant onto the stalk of another could improve the quality of crops.
Now, researchers at the Salk Institute and Cambridge University have used this ancient practice, combined with modern genetic research, to show that grafted plants can share epigenetic traits, according to a new paper published the week of January 18, 2016 in the Proceedings of the National Academy of Sciences.
In results published on October 19, 2015 in the Journal of Lipid Research, a team of translational scientists at the Medical University of South Carolina (MUSC) report a new reason why non-alcoholic steatohepatitis (NASH) worsens in people who are obese.
The results may help prevent cirrhosis and liver cancer, according to co-senior authors Kenneth D. Chavin, M.D., PhD, a transplant surgeon in the MUSC Health Department of Surgery, and Lauren Ashley Cowart, PhD, Associate Professor of Biochemistry and Co-Director of the MUSC Center of Biomedical Research Excellence in Lipidomics and Pathobiology.
As musicians, figure skaters and anyone who takes a driving test will know, the anxiety of being watched can have a disastrous effect on your performance.
Now neuroscientists at the University of Sussex's Sackler Centre and Brighton and Sussex Medical School have identified the brain network system that causes us to stumble and stall just when we least want to.
Dr Michiko Yoshie and her colleagues Professor Hugo Critchley, Dr Neil Harrison, and Dr Yoko Nagai were able to pinpoint the brain area that causes the performance mishaps during an experiment using functional magnetic resonance neuroimaging (fMRI).
The quality of your writing will likely get better if you simply type slower, according to a recent study.
Researchers from the University of Waterloo asked study participants to type essays using both hands or with only one. Using text-analysis software, the team discovered that some aspects of essay writing, such as sophistication of vocabulary, improved when participants used only one hand to type.
"Typing can be too fluent or too fast, and can actually impair the writing process," said Srdan Medimorec, a PhD candidate in the Faculty of Arts at Waterloo and lead author of the study. "It seems that what we write is a product of the interactions between our thoughts and the tools we use to express them."
People of the Neolithic age around 6,000 years ago were closely connected both in life and death. This became evident in a detailed archaeological and anthropological of a collective grave containing 50 bodies near Burgos, northern Spain. In the pioneering study, researchers used a whole array of modern methods to examine the way of life in the region at that time.
MAYWOOD, Ill. - A study by researchers at Loyola University Medical Center and Loyola University Chicago is providing new evidence that the vast majority of babies who are born with severe brain damage are not the result of mismanaged deliveries.
Lead author Jonathan Muraskas, MD, and colleagues examined the medical records of 32 full-term infants who developed severe cerebral palsy and mental retardation. The records indicate that this brain damage occurred after the babies were born, and despite proper resuscitation.
The study is published in the Journal of Perinatology
Pearls have adorned the necklines of women throughout history, but some evidence suggests that the gems' future could be uncertain. Increasingly acidic seawater causes oyster shells to weaken, which doesn't bode well for the pearls forming within. But, as scientists report in ACS' journal Environmental Science & Technology, the mollusks might be more resilient to changing conditions than previously thought.
