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.
For the first time, an international collaboration of researchers have succeeded in creating a complete overview of all pain conditions in the face, mouth and jaw and classifying them in the same way.
This means that medical doctors and dentists will have a common language and the same understanding of this pain. In turn, this will benefit the diagnosing of patients and thus the patients themselves, says professor of pain research Peter Svensson from the Department of Dentistry and Oral Health at Aarhus University, Denmark.
ITHACA, N.Y. - Muscle repair is a crowded, complicated business. Many different types of cells are bumping around, chattering and trying to coordinate with each other as they work to regenerate new tissue.
Research at North Carolina State University shows that the CRISPR-Cas system can be used to effectively target and eliminate specific gut bacteria, in this case Clostridioides difficile, the pathogen that causes colitis - a chronic, degenerative disease of the colon.
In a proof-of-concept study published in the journal mBio, researchers were able to show pathogen reductions in experiments conducted both on the lab bench and in mice.
An avocado a day improves the ability to focus attention for overweight or obese adults, Illinois researchers found in a new study.

CHAMPAIGN, Ill. -- A diet including daily avocado consumption improves the ability to focus attention in adults whose measurements of height and weight are categorized as overweight or obese, a new randomized control trial found.
Pancreatic cancer is predicted to become the second leading cause of cancer-related deaths by 2030. However, recent developments in staging and treatment provide options to improve the long-term survival rate for an otherwise devastating diagnosis.
Today, new research published in Annals of Surgery from the University of Colorado Department of Surgery at the Anschutz Medical Campus offers a roadmap to new guidelines for physicians in prioritizing treatments and improving outcomes through surgery.
The behavior of one of nature's humblest creatures is helping astronomers probe the largest structures in the universe.
Enzymes are nature's powerhouses. Found in the cells of all animals, plants, and every other living organism, they accelerate the chemical reactions that trigger thousands of biological functions--from forming neurons to digesting food.
