People with a certain heart valve abnormality are at increased risk of severe heart rhythm disorders, even after successful valve surgery. The condition is more common in women and younger patients with valve disorder and can, in the worst case, lead to sudden cardiac arrest.

A new study questions the longstanding view that the visual system is divided into two pathways, one for object-recognition and the other for spatial tasks. Using computational vision models, researchers found the ventral visual stream, may not be exclusively optimized for object recognition.

Researchers investigated the quantities of thousands of muscle proteins and found a possible new explanation for muscle memory. A study showed for the first time that muscles 'remember' training at the protein level. The memory trace of previous resistance training persists in muscle proteins for over two months.

Growing cells in the laboratory is an art that humans have mastered decades ago. Recreating entire three-dimensional tissues is much more challenging. Researchers are developing a new hydrogel-based material that makes it possible to engineer artificial skin tissues, which can serve as living three-dimensional models of human skin for better understanding and treating skin diseases.
