Gut microbiota influences the ability to lose weight in humans, according to new research. The findings were published this week in mSystems, an open-access journal of the American Society for…
Water can freeze from liquid to solid ice or boil into a gas. In the kitchen these “phase transitions” aren’t smooth, but their discontinuous nature is smoothed out at high…
The strongest associations with weight loss success or failure, independent of BMI, are found in the genetic capacity of the gut microbiome, new research from Institute for Systems Biology (ISB)…
As we age, our bones become thinner, we suffer fractures more often, and bone-diseases such as osteoporosis are more likely to occur. One responsible mechanism involves the impaired function of…
Researchers insert a vacuum line down a borehole in Megadunes, Antarctica, to pump air out of the snow pack. Researchers at UCI analyzed the “firn” air to determine that the…
