A mother’s diet can have a lasting impact on offspring

A new study published in Physiological Reports provides evidence that a mother’s diet during pregnancy could have lasting impacts on her offspring’s bone development and later risk of osteoporosis. Osteoporosis is characterized by a loss of trabecular (spongy) bone leading to increased risk for developing bone fractures.  The researchers discovered this relationship while studying female microswine that were consuming a diet containing only 1% protein late in their pregnancy and for […]

Growth restriction in utero increases risk for developing insulin resistance

  A new study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology, explored how restricted growth of a fetus during pregnancy can lead to insulin resistance later in life. They studied this risk factor in guinea pigs as larger litter sizes are known to restrict the growth of developing fetuses. Findings from the study showed that neonatal guinea pigs grow rapidly after birth to compensate for […]

Brine shrimp tolerance of environmental changes

Brine shrimp, Artemia franciscana, are neat little aquatic crustaceans. According to the University of Utah, these tiny creatures grow to about 1cm in length. They are a favorite meal choice of some migratory birds and they are often sold for use as food for fish destined for human consumption. Christopher Melendez, a graduate student in the lab of Dr. Casey Mueller at California State University San Marcos, presented his research on brine […]

How to grow a bigger heart…

…in alligators at least. Researchers from the University of Manchester, University of North Texas – Denton, and the Rockefeller Wildlife Refuge – Grand Chenier, Louisiana teamed up to explore the effects of exposure to low oxygen on embryonic American alligators (Alligator mississippiensis). Alligator eggs are often laid in nests where oxygen concentrations can reportedly vary between 11-20% (21% is normal atmospheric levels). This is really important as issues related to embryonic development could continue to affect animals throughout their adult lives […]
