Lasers that can flip cells off and on and brain scanners that can be worn are just two projects receiving federal grants as a part of the $100 million BRAIN Initiative aimed to learn more about the inner-workings of the brain.

Following World Alzheimer's Day, a list of recent Alzheimer's studies, including brain PET research, was recently published by

Altruistic people, such as those who would be willing to donate an organ to a stranger, show a stronger response to fearful faces in the form of a spike of activity in the amygdala when scanned using fMRI, according to a feature in the Discover D-Brief Blog.

The U.S. National Institutes of Health (NIH) has set an initiative in motion that intents to banish a biomedical research bias toward the use of male animal models and cells in preclinical studies.

Makers of F-18 florbetapir (Amyvid) are bankrolling a lawsuit against the Centers for Medicare & Medicaid Services (CMS), which hampered coverage of amyloid imaging earlier this year as a means for ruling out Alzheimer’s disease. The lawsuit was filed in federal court by Lilly and others Sept. 5, according to this Wall Street Journal report.

The Centers for Medicare & Medicaid Services (CMS) has provided projected U.S. healthcare spending for the next several years and it is modest. Due to a timid economy and higher private insurance plan costs that pinch demand for healthcare services, average annual healthcare spending is expected to grow by 5.7 percent this year and just about 6 percent from 2013 to 2023.

In the world of cancer screening, there may be a bias of accessibility that is skewed toward more screening when doctors are paid more by Medicaid, according to a study conducted by the division of health services and social policy research at RTI International in Washington, D.C.

Researchers from the University of California, Davis, have created dynamic nanoparticles that can be used to both diagnose and treat cancer.

Chronic pain is associated with a reduction in reward seeking, but not just because people are hurting and do not feel up to the task. New Stanford brain research is providing a more comprehensive picture of how molecular changes in the brain dictate loss of motivation in painful settings.

It is easy to create generics from conventional drugs, but not so for biologics, which involve active biological ingredients such as proteins that can be leveraged to treat cancer and a range of other diseases. Biosimilars, which mimic biologics as closely as possible, could be the next big thing in the U.S., but a hot debate has been pitched over what to name these drugs.

A treatment for stroke involving optogenetics fires up neurons in the motor cortex by way of a beam of light. This treatment has been shown in preclinical research to improve movement and coordination after a stroke, say researchers at Stanford University in Stanford, Calif.
