• 22:24 PET techniques provide more accurate diagnosis, prognosis in challenging breast cancer cases

  Read the story at PhysOrg
  In two new studies featured in the February issue of the Journal of Nuclear Medicine, researchers are revealing how molecular imaging can be used to solve mysteries about difficult cases of breast cancer. One article focuses on an imaging agent that targets estrogen receptors in estrogen receptor–positive breast cancer patients with formerly inconclusive assessments, and the second highlights a different imaging agent's ability to help predict the prognosis for patients undergoing chemotherapy for a very aggressive type of breast cancer.

  Read the story at PhysOrg
  When William Murphy works with some of the most powerful tools in biology, he thinks about making tools that can fit together. These constructions sound a bit like socket wrenches, which can be assembled to turn a half-inch nut in tight quarters, or to loosen a rusted-tight one-inch bolt using a very persuasive lever.

• 22:24 Visual working memory not as specialized in the brain as visual encoding, study finds

  Read the story at PhysOrg
  Researchers have long known that specific parts of the brain activate when people view particular images. For example, a region called the fusiform face area turns on when the eyes glance at faces, and another region called the parahippocampal place area does the same when a person looks at scenes or buildings. However, it's been unknown whether such specialization also exists for visual working memory, a category of memory that allows the brain to temporarily store and manipulate visual information for immediate tasks. Now, scientists have found evidence that visual working memory follows a more general pattern of brain activity than what researchers have shown with initial visual activity, instead activating a more diffuse area in the front of the brain for all categories of visual stimuli.
