Sugar-burning in the adult human brain is associated with continued growth, and remodeling

Research published in Cell Metabolism reveals that hotspots of fuel consumption in the adult brain are associated with ongoing development and remodeling. The study identifies 16 brain regions with elevated levels of aerobic glycolysis, which is linked to gene expression related to growth, synaptic transmission, and neurogenesis.

When germs attack: A lens into the molecular dance

Researchers at Johns Hopkins have identified a pathogen sensor called IFI16 that plays a crucial role in recognizing viruses and bacteria. The study reveals that IFI16 uses the length of DNA as a molecular ruler to distinguish self from non-self, which could lead to new treatments for autoimmune disorders.

Neurotransmitters resarch can promote better drugs for brain disorders

Researchers at Hebrew University deciphered the mode by which neurotransmitter inhibitors work, raising hopes for new and effective drugs for brain disorders. The study used baker's yeast as a model and identified flexible domains in the structure of the vesicular monoamine transporter (VMAT) responsible for tetrabenazine binding.

The loving touch is critical for premature infants

A decade-long study shows that providing maternal-newborn skin-to-skin contact enhances child physiologic organization and cognitive control, leading to better neuroendocrine response to stress. The intervention, called Kangaroo Care, also improves children's functioning in systems sensitive to early maternal deprivation.

MRSA infection rates drop in Veterans Affairs long-term care facilities

A study published in the American Journal of Infection Control found a significant decrease in MRSA infections in Veterans Affairs long-term care facilities over a 42-month period. The MRSA Prevention Initiative, which included screening, hand hygiene, and institutional culture change, led to a 36% overall decline in MRSA infections.
