Some say you’re only as old as you feel. Others say you’re as young as you think. But how old is your brain really?
Social media may heighten depression severity in youth
An emotional overattachment to social media may be associated with increased severity of mental health symptoms among young people being treated for depression, anxiety, and suicidal thoughts, according to researchers at UT Southwestern Medical Center.
New neuron-targeting method may reduce anxiety and blood pressure
Every year, heart disease claims the lives of more Americans than any other health condition, according to the Centers for Disease Control and Prevention. One of the key risk factors for heart disease is high blood pressure. New research by two Georgia State University professors published in The Journal of Neuroscience suggests that relieving psychological stress by targeting specific neurons in the brain can lower blood pressure and reduce anxiety.
Poor neighborhoods, health care barriers are factors for heart disease risk in Black mothers
Living in a disadvantaged neighborhood contributes to a rare form of heart failure known as peripartum cardiomyopathy, a potentially deadly disease that disproportionately affects Black mothers.
Rethinking repression: Why memory researchers reject the idea of recovered memories of trauma
In 1990, George Franklin was convicted of murder and sentenced to life in prison based on the testimony of his 28-year-old daughter Eileen. She described seeing him rape her best friend and then smash her skull with a rock.
Childhood brain injuries can affect educational attainment in adulthood—study shows concussion can be enough
A study conducted at Tampere University shows that a blow to the head can significantly impact a child’s or adolescent’s future education and, consequently, their career. Even a mild concussion can have far-reaching consequences. The research article “Impact of childhood traumatic brain injury on educational attainment in Finland from 1998 to 2018: A retrospective register-based nationwide cohort study” was published in the European Journal of Epidemiology on 23 March 2025.

Diabetic foot pain: Expert tips on how to cope
An estimated 1 in 10 people worldwide have diabetes. Africa is the region with the fastest growth and it’s estimated that the number of people on the continent with diabetes will more than double in the next 20 years, increasing to about 55 million people by 2045.
Revealing brain energy dynamics: Decoding the response to epileptic seizures
Cell survival depends on the energy molecule adenosine triphosphate (ATP)—it’s like the fuel that keeps our brain running. Intracellular ATP levels are thought to remain constant, given its importance. To maintain this stability, the brain strikes a delicate balance between metabolic energy supply and how much energy our brain is using (neuronal activity).
Scientists identify potential new genetic target for sickle cell disease treatment
Scientists from Johns Hopkins Medicine and eight other institutions in the United States, Africa and Europe say they have identified a potential new gene target that could be edited to treat sickle cell disease, an inherited blood disorder marked by sickle-shaped red blood cells that cause intense pain and shorten lifespans.
