Small differences in mom’s behavior may show up in child’s epigenome

Posted by in categories: biotech/medical, genetics

Adding evidence to the importance of early development, a new study links neutral maternal behavior toward infants with an epigenetic change in children related to stress response.

Epigenetics are molecular processes independent of DNA that influence gene behavior. In this study, researchers found that neutral or awkward behavior of mothers with their babies at 12 months correlated with an epigenetic change called methylation, or the addition of methane and carbon molecules, on a gene called NR3C1 when the children were 7 years old. This gene has been associated with regulating the body’s response to stress.

“There is evidence of a relationship between the quality of maternal-infant interaction and methylation of this gene though these are small effects in response to a relatively small variation in interaction,” said Elizabeth Holdsworth, a Washington State University biological anthropologist and lead author of the study published in the American Journal of Human Biology.

This Startup Is Making Ultra-Strong Building Panels Out of Grass

Posted by in category: materials

After testing several different types of grass and other raw materials, Plantd settled on a perennial (meaning it grows back every year and doesn’t need to be re-planted) long grass that can grow 20 to 30 feet in a year.

Though grass is obviously softer than wood, it contains a similar cellulose fiber that can be broken down then reconstituted and engineered in such a way that the final product is even stronger than wood (check out this video that made the rounds on LinkedIn last year: a regular wood panel and a Plantd panel are subjected to a sledgehammer, and just one of the two withstands the test).

Poor sleep linked to years of poor cardiovascular health

Posted by in categories: biotech/medical, health

Poor sleep could lead to between two and seven years worth of heightened heart disease risk and even premature death, according to a new study led by researchers at the University of Sydney in collaboration with Southern Denmark University.

The study analyzed data from more than 300,000 middle-aged adults from the UK Biobank and found that different disturbances to sleep are associated with different durations of compromised later in life compared to healthy sleepers.

In particular, men with clinical sleep-related breathing disorders lost nearly seven years of cardiovascular disease-free life compared to those without these conditions, and women lost over seven years. Importantly, even general , such as insufficient sleep, insomnia complaints, snoring, going to bed late, and is associated with a loss of around two years of normal heart health in men and women.
