Steps have dropped since Covid-19 and the trend is worrisome, study says | CNN
Step trackers show Americans reduced their daily step counts when Covid-19 appeared, and have yet to return to pre-pandemic levels, a new study found.
Child growth and development hampered by PFAS in blood, study says | CNN
Human-made chemicals called PFAS alter pathways needed for human growth and development, according to a recent study analyzing blood samples from young children, teens and young adults.

NCBI’s Genome Decoration Page (GDP) to Retire in September 2023
As of September 2023, NCBI’s Genome Decoration Page (GDP) will no longer be available. Due to low usage of GDP, we are focusing our development efforts on our more popular resources and tools. If you are using GDP to view your data mapped to genomes, we encourage you to check out our Genome Data Viewer (GDV) … Continue reading NCBI’s Genome Decoration Page (GDP) to Retire in September 2023
Artificial Pancreas Improves Blood Glucose Control in Young Kids with Type 1 Diabetes
Last week brought some great news for parents of small children with type 1 diabetes (T1D). It involved what’s called an “artificial pancreas,” a new type of device to monitor continuously a person’s blood glucose levels and release the hormone insulin at the right time and at the right dosage, much like the pancreas does in kids who don’t have T1D.
