High-sugar diets: Discovering human impacts through animal models

Featured Article

High-sugar diets can have many negative effects. One way to pinpoint the physical changes they can cause in humans is to test their effects on animal models that share similarities with humans. Featured articles (these articles have been added to the Science Primary Literature database): *Alcántar-Fernández, J., González-Maciel, A., Reynoso-Robles, R., Martha Elva Pérez Andrade, de J Hernández-Vázquez, A., Velázquez-Arellano, A., & Miranda-Ríos, J.

Preterm birth and kidney disease: the risk

Featured Article

“Preterm birth (<37 gestational weeks) interrupts the development and maturation of the kidneys during a critical growth period. The third trimester of pregnancy is the most active period of fetal nephrogenesis [development of the kidney], during which more than 60% of nephrons [the functional units of the kidney] are formed.” Interruption of this process results in a lower nephron number that is lifelong. “Lower nephron…

Cancer: is it part of evolution? What can we learn from cancer in animals?

Featured Article

Domestic and wild animals get cancer. Animals, like humans, see an increase in cancer when living in areas of heavy chemical contamination. But, some animal species rarely get cancer; why? And, if any cell could become cancerous, why don’t larger animals have a greater risk of cancer than smaller animals? Animals far larger than humans–like elephants–rarely get cancer. That must mean their cells somehow fight…

Lack of sleep linked to cardiovascular problems

News

We know that sleep is vital for humans. Lack of sleep, sleep disruption, changes in sleep habits, and more can lead to real problems–physical and mental. For example, we know that not getting enough sleep leads to millions of lost work days and a huge annual economic loss … a problem especially severe in the United States. And, we know that sleep disruption and lack…

How far do COVID-19 particles travel from people who are infected?

News

Many governments have recommended social distancing guidelines of 6 feet (about 2 meters). A study using surface and air samples obtained in February and early March 2020 “from an intensive care unit (ICU) and a general COVID-19 ward [GW] at Huoshenshan Hospital in Wuhan, China” came to a different conclusion–a maximum transmission distance of about 13 feet. “The main transmission routes for SARS-CoV-2 [COVID-19] are…
