Over the last five years scientists at King's College London have been investigating a method of stimulating natural tooth repair by activating cells in the tooth to make new dentine. In a paper published today in the Journal of Dental Research, they have found further positive evidence that the method has the potential to be translated into a direct clinical approach.
When teeth suffer damage either by decay or trauma, there are three layers that may be affected:
1. the outer enamel,
Parents of children with genetic conditions that cause learning disabilities are at risk of mental health problems, suggests new research published today in the British Journal of Psychiatry. The teams behind the study have called for greater support for parents whose child receives a genetic diagnosis for their learning disability.
A baby's development at 18 months old is not adversely affected by being left to 'cry it out' a few times or often in infancy researchers at the University of Warwick have found.
The use of letting baby cry it out by parents was rare at term but was increasingly used by parents over the first 18 months of life in this UK sample. A third of parents never let their baby cry it out in infancy.
Mothers who let babies "let it cry out" a few times or often were not less sensitive in their parenting in direct observations of mother-baby interaction.
From being raised by an emotionally cold mother to experiencing violence, war and bereavement, difficult life events have a profound effect on our physical and mental wellbeing in later life - according to new research from the University of East Anglia.
A new study published today shows how a range of life inequalities and hardships are linked to physical and mental health inequalities in later life.
While lifestyle choices and genetics go a long way toward predicting longevity, a new study shows that certain community characteristics also play important roles. American communities with more fast food restaurants, a larger share of extraction industry-based jobs, or higher population density have shorter life expectancies, according to researchers from Penn State, West Virginia, and Michigan State Universities. Their findings can help communities identify and implement changes that may promote longer lifespans among their residents.
WASHINGTON, March 10, 2020 -- Scientists watched the formation of a self-emergent machine as stem cell-derived neurons grew toward muscle cells in a biohybrid machine, with neural networks firing in synchronous bursting patterns. The awe-inspiring experiment left them with big questions about the mechanisms behind this growth and a proven method of capturing data for continued study of bioactuators.
About 1 in 40 postmenopausal women diagnosed with breast cancer before age 65 have cancer-associated mutations in their BRCA1 or BRCA2 genes, according to a Stanford-led study of more than 4,500 participants in the long-running Women's Health Initiative.
The brain jiggles when the heart beats, and now, researchers have found a way to use that motion to better study the differences between types of neurons. In a study appearing March 10 in the journal Cell Reports, researchers find that by analyzing the changes in the waveforms they record from neurons during a heartbeat, they can more accurately classify the different types of neurons in the human brain. This work, they say, could help us better understand how the different types of cells that exist in the brain interact together to produce cognition and behavior.
Texans who are college-educated, live in suburban or urban areas, have higher median incomes and are ethnically white are less likely to vaccinate their children, according to analysis by researchers at The University of Texas at Austin. The findings could help public health officials identify pockets of low vaccination rates where communities within the state are at higher risk for an outbreak of vaccine-preventable diseases such as measles.
Large ecosystems, such as the Amazon rainforest, will collapse and disappear alarmingly quickly, once a crucial tipping point is reached, according to calculations based on real-world data.
Writing in Nature Communications (10.1038/s41467-020-15029-x), researchers from Bangor University, Southampton University and The School of Oriental & African Studies, University of London, reveal the speed at which ecosystems of different sizes will disappear, once they have reached a point beyond which they collapse - transforming into an alternative ecosystem.
Studying gamma ray emissions from phenomena like supermassive black holes allows astrophysicists to better conceptualize the behavior of matter under extreme conditions. Although dark matter is thought to account for roughly a quarter of all energy content in the cosmos, its relationship with gamma rays is mysterious. Now, Ammazzalorso et al. have found the first direct cross-correlation between gamma rays and matter in the Universe.
INDIANAPOLIS - It is common for critically ill patients on life support to develop delirium, a form of acute brain failure for which no effective treatment is known. A study from Indiana University School of Medicine and Regenstrief Institute researchers reports that music appears to decrease delirium in patients on mechanical ventilators in the intensive care unit (ICU).
New international research by Woods Hole Oceanographic Institution (WHOI) and colleagues has found a marked change in the Indian Ocean's surface temperatures that puts southeast Australia on course for increasingly hot and dry conditions.
The work led by The Australian National University (ANU) and the ARC Centre of Excellence for Climate Extremes has a silver lining, helping to improve our understanding of climate variations and the management of risk caused by Indian Ocean variability.
Nearly 94% of defendants in Cuyahoga County drug court have been exposed to trauma and many suffer from symptoms of post-traumatic stress disorder (PTSD), according to a new Case Western Reserve University study.
"These findings tell us that we need to not only treat the disease of addiction, but also the underlying mental-health issues that so often coincide with them," said Margaret Baughman, co-author of the study and a senior research associate at the Center on Trauma and Adversity at the university's Jack, Joseph and Morton Mandel School of Applied Social Sciences.
A new study published in the Journal of Nutrition Education and Behavior (JNEB) builds on years of previous research studies and demonstrates the value of family meals. This study showed that more frequent family meals were associated with better dietary outcomes and family functioning outcomes. While Americans celebrate the month of March as National Nutrition Month, these findings underscore the myriad benefits advanced by family meals advocates over the past few years and punctuate the official launch of the Family Meals Movement.
