A new study offers insight into what is happening in our brains when our working memory must use its limited resources to remember multiple things.

Low iron is common in teenage girls, with vegans and vegetarians at greatest risk, according to research
Teenage girls who avoid meat in favor of a plant-based diet are at higher risk of developing an iron deficiency, according to our latest research.
Researchers report association between urinary incontinence, cardiovascular disease
A University of Iowa-led research team has found that urinary incontinence may be associated with a greater risk of cardiovascular disease in women. The work is published in the journal Preventive Medicine.
Why were people so drawn to phrenology?
It’s hard to imagine now, but people once believed that the bumps on your head could reveal your personality. For one thing, it’s so hard to locate the bumps on your head, let alone the thirty or so bumps the phrenologists said could be discerned. So why was phrenology such an attractive idea for such a long time?
Pushing the limits of brain imaging: A new tool for targeted delivery of imaging agents and drugs
Multiphoton microscopy is a valuable tool for neuroscience research, allowing scientists to observe functional brain activity in real time through high-resolution imaging. An essential component of many multiphoton microscopy imaging studies is the delivery of chemical compounds, including imaging agents and drugs. However, many compounds cannot cross the blood-brain barrier and, therefore, cannot be delivered to the brain through systemic administration.
Researchers explore adapted Argentine dance therapy for cancer survivors
Adapted Argentine tango dance therapy is helping some breast cancer survivors regain natural balance and sensation after experiencing neuropathy, a common side effect of chemotherapy treatment. Expansion of a new clinical study will look further at how this musical movement intervention can “rewire” the brain to improve function after chemotherapy-related nerve changes.
Discovery of FOXR2 activation in various brain tumors refines diagnosis to improve care
Physicians classify brain tumors and determine treatment options, in part, by the genes they express. According to World Health Organization standards, the abnormal activation of oncogene FOXR2 only occurs in central nervous system (CNS) neuroblastoma, but that may not be true. Findings from St. Jude Children’s Research Hospital show FOXR2 activation in multiple pediatric CNS tumor types, mostly brain tumors, with significantly different clinical outcomes.
Even vegans who get enough total protein may fall short for some essential amino acids, findings suggest
In a new study of people with long-term vegan diets, most ate an adequate amount of total daily protein, but a significant proportion did not meet required levels of the amino acids lysine and leucine. Bi Xue Patricia Soh and colleagues at Massey University, New Zealand, present these findings in the open-access journal PLOS One.
Lifelong physical activity may slow cognitive decline
High levels of physical activity may mitigate brain loss in adults and help maintain long-term cognitive health, researchers at UT Southwestern Medical Center report in a study published in the Journal of Applied Physiology.
New human ‘multi-zonal’ liver organoids improve injury survival in rodents
One reason why our livers excel at clearing waste from our blood system is that the organ functions according to three key “zones” that perform specific major tasks. So, if scientists hope to create self-growing patches of liver organoid tissue that could help repair damaged organs, it’s important that the lab-grown tissue faithfully reproduce such zones.
