- Scientists identify genetic components of left-handedness
In a genetic analysis of 400,000 people, scientists have, for the first time, identified four DNA regions associated with left-handedness.
- Listening and reading evoke almost identical brain activity
By constructing 3D semantic maps, scientists have shown that the brain activity of comprehension is largely similar for listening and reading.
- What to know about a blood clot in the arm
A blood clot in the arm can be a dangerous health problem. If the clot dislodges and travels to the lungs, it can block the flow of blood there, causing the tissue to die. As a result, a blood clot in …
- Why does insomnia worsen distress of unpleasant memories?
Brain activity differences may help explain why distress from bad memories grows stronger in people with insomnia but fades in those without insomnia.
- MS: High-strength MRI may predict disease progression
New research suggests that a powerful MRI scanner may help predict the progression of multiple sclerosis by analyzing cortical lesions on the brain.
- Stimulating brain with ultrasound can influence decisions
A study in macaques reveals that targeting a brain region with noninvasive, low-intensity ultrasound can alter a specific decision-making process.
- Dementia: Amyloid PET scans can improve diagnosis and care
Using brain scans that can detect hallmarks of Alzheimer's could improve diagnosis and clinical care of people with dementia and mild cognitive impairment.
- Atherosclerosis: Scans spot inflammation in arteries before they harden
Using advanced imaging to scan people with some atherosclerotic plaques, scientists detected inflammation in arteries that had not yet developed plaques.

A study of older adults links blood markers of certain nutrients that are present in the Mediterranean diet to better cognition and brain connectivity.
- MS: Disease impact is greater in those with food allergies
People with MS and a reported history of food allergy had more relapses and were likelier to have active lesions on MRI scans than those without allergy.
- What does autism look like in the brain?
A new study offers a fresh perspective on how autism works in the brain. Symptoms, the authors say, may be linked to persistent connections in the brain.
- Depression: Three new subtypes identified
Scientists used functional MRI to study the brains of 134 people and identified three new subtypes of depression, including a treatment-resistant subtype.
- Does COPD show up on an X-ray?
Diagnosing chronic obstructive pulmonary disease can involve an X-ray, which may show enlarged lungs and diaphragm problems. Doctors may order X-rays and other tests when a person has symptoms, such a …

A doctor may use a head and brain MRI scan to check for a range of injuries and abnormalities. Here, gain a detailed understanding of the procedure and how to prepare.
- MS: Iron levels in brain 'predict disability'
A new type of MRI that accurately monitors irons levels in different brain areas could help identify MS patients at higher risk of physical disability.
- What are phleboliths and are they safe?
Phleboliths are small, round lumps of calcium that form inside a person's veins. This type of vascular calcification often occurs in the pelvic area and is more common with age. Phleboliths frequ …
