Clearing out the clutter: how people retain important information from memories
2025-06-16
Removing information from memories may help people retain what they want to remember. Studies focus on how the brain removes information by subconsciously not paying attention to these details, but sometimes there is a need to consciously remove unneeded details from memories. This is especially true when details in a memory are perceptibly harmful and lead to, for example, people combating rumination, intrusive negative thoughts, or hallucinations. In a new JNeurosci paper, Jiangang Shan and Bradley Postle, from the University of Wisconsin-Madison, explored how the brain actively removes unneeded memory content.
The researchers recorded the brain activity of nearly 30 ...
High blood pressure in pregnancy linked to increased risk of seizure in children
2025-06-16
A new study led by researchers at University of Iowa Health Care has revealed a significant association between high blood pressure during pregnancy (gestational hypertension) and an increased risk of seizures in children.
The study, published June 16 in the Journal of Clinical Investigation, used extensive clinical databases and innovative animal models to uncover this critical link. The findings also suggest that inflammation in the brain may play a role in connecting gestational hypertension to seizure risk and could potentially be targeted to prevent seizures in children exposed to hypertension in the womb.
Clinical data links seizure risk in children ...

Official US records underestimate Native Americans deaths and life expectancy
2025-06-16
A new study in JAMA reveals the “statistical erasure” of Indigenous Americans, finding that the gap between AI/AN life expectancy and the national average was 2.9 times greater than official vital statistics indicate.
Death rates for American Indians’ and Alaska Natives (AI/AN) are far higher than reported in official vital statistics, according to a new study led by a Boston University School of Public Health (BUSPH) researcher.
Published in JAMA, the nationally representative study found that death certificates for at least 41 percent of AI/AN decedents failed to identify them as AI/AN, in most cases misreporting ...
Father’s mental health plays key role in child development, research shows
2025-06-16
Experts from Ann & Robert H. Lurie Children’s Hospital of Chicago affirm the need to screen new fathers for mental distress, recognizing the mounting research that underscores the importance of fathers in child development. Their invited commentary, published in JAMA Pediatrics, accompanies a systematic review, which found that paternal depression, anxiety and stress in the perinatal period are associated with poorer child development in social, emotional, cognitive and language domains.
“Birth of a child can be highly stressful for both parents,” said lead author Craig Garfield, MD, MAPP, pediatrician and founder of the Family & Child Health Innovations ...
Public water arsenic and birth outcomes in the Environmental Influences on Child Health Outcomes Cohort
2025-06-16
About The Study: In this cohort study of birthing parent–infant dyads across the U.S., arsenic measured in public water systems was associated with birth outcomes at levels below the current U.S. Environmental Protection Agency’s maximum contaminant level. The findings suggest that further reducing the maximum contaminant level for arsenic may decrease the number of infants with low birth weight in the U.S.

Immune tolerance to gut microbes is initiated by a key bacterial sensor
2025-06-16
Thousands of bacterial and other microbial species live in the human gut, supporting healthy digestion, immunity, metabolism and other functions. Precisely how these microbes are protected from immune attack has been unclear, but now a study led by Weill Cornell Medicine investigators has found that this immune “tolerance” to gut microbes depends on an ancient bacterial-sensing protein called STING—normally considered a trigger for inflammation. The surprising result could lead to new treatments for inflammatory bowel disease and other conditions involving gut inflammation.
In their ...
The genomic organization of ant superorganisms
2025-06-16
Aristotle praised the political organization of ant colonies while ancient Chinese Daoists appreciated ants as illustrative symbols showing how ephemeral human ambitions and power are. Throughout historical and pre-historic times, ant-workers are likely to be the first insects that toddlers relate to when they crawl around on all four.
Similar to so much else in biology, the first scientific understanding of ants goes back to Darwin, who spent many pages of the Origin of Species (1859) on these conspicuous social insects. Their very existence seemed to fly ...
High levels of troponin in athletes are not caused by narrowed coronary arteries
2025-06-16
Exercising is healthy, but it also puts strain on the heart. During physical exertion, the protein troponin is released—a biomarker indicative of cardiac damage. New research from Radboudumc involving a thousand athletes shows that elevated troponin levels after exercise are not due to coronary atherosclerosis. This suggests that the cause of elevated troponin levels after exertion lies elsewhere.
It’s a paradox: regular exercise is healthy and reduces the risk of cardiovascular disease, yet it also ...
First patient in the world treated for muscle-weakness disease in clinical trial at HonorHealth Research Institute
2025-06-16
SCOTTSDALE, Ariz. — June 16, 2025 — The first patient enrolled in a planned international clinical trial has been treated at HonorHealth Research Institute with a new type of immune therapy for those with a rare muscle-weakness disease known as Myasthenia Gravis.
In an odd medical twist, this auto-immune disease — in which antibodies interfere with the connection between nerves and muscles — most often strikes young women in their 20s and 30s, and older men in their 60s and 70s, though it can affect others.
The disease affects fewer than 200 in every 1 million people. Symptoms range from droopy eyelids, problems ...

In stereo: neurons shift gears between thoughts using brain rhythms
2025-06-16
The brain is constantly mapping the external world like a GPS, even when we don't know about it. This activity comes in the form of tiny electrical signals sents between neurons -- specialized cells that communicate with one another to help us think, move, remember and feel. These signals often follow rhythmic patterns known as brain waves, such as slower theta waves and faster gamma waves, which help organize how the brain processes information.
Understanding how individual neurons respond to these rhythms is key to unlocking how the brain functions related to navigation in real time – and how it may be affected in disease.
