Today's health science headlines from the sources selected by our team:

Calcium may play a role in the development of Parkinson's disease
Researchers have found that excess levels of calcium in brain cells may lead to the formation of toxic clusters that are the hallmark of Parkinson's disease.

Studying mitosis' structure to understand the inside of cancer cells
Cell division is an intricately choreographed ballet of proteins and molecules that divide the cell. During mitosis, microtubule-organizing centers assemble the spindle fibers that separate the copying chromosomes of DNA. While scientists are familiar with MTOCs' existence and the role they play in cell division, their actual physical structure remains poorly understood. Researchers are now trying to decipher their molecular architecture.

Ras protein's role in spreading cancer
Protein systems make up the complex signaling pathways that control whether a cell divides or, in some cases, metastasizes. Ras proteins have long been the focus of cancer research because of their role as 'on/off switch' signaling pathways that control cell division and failure to die like healthy cells do. Now, a team of researchers has been able to study precisely how Ras proteins interact with cell membrane surfaces.

An enzyme's evolution from changing electric fields and resisting antibiotics
(Biophysical Society) Bacteria can produce enzymes that make them resistant to antibiotics; one example is the TEM beta-lactamase enzyme, which enables bacteria to develop a resistance to beta-lactam antibiotics, such as penicillin and cephalosporins. Researchers at Stanford University are studying this area -- how an enzyme changes and becomes antibiotic-resistant -- and will present their work during the Biophysical Society's 62nd Meeting, held Feb. 17-21, 2018.

Calcium may play a role in the development of Parkinson's disease
(University of Cambridge) Researchers have found that excess levels of calcium in brain cells may lead to the formation of toxic clusters that are the hallmark of Parkinson's disease.

Lack of guidance may delay a child's first trip to the dentist
(Michigan Medicine - University of Michigan) Without a doctor or dentist's guidance, some parents don't follow national recommendations for early dental care for their children, a new national poll finds.
