The gut microbiome is an integral component of the body, but its importance in the human aging process is unclear. ISB researchers and their collaborators have identified distinct signatures in the gut microbiome that are associated with either healthy or unhealthy aging trajectories, which in turn predict survival in a population of older individuals. The work is set to be published in the journal

A team of researchers has devised a method using smartphones in order to measure food consumption an approach that also offers new ways to predict physical well-being. We ve harnessed the expanding presence of mobile and smartphones around the globe to measure food consumption over time with precision and with the potential to capture seasonal shifts in diet and food consumption patterns, explains Andrew Reid Bell, an assistant professor in New York University s Department of Environmental Studies and an author of the paper, which appears in the journal
Environmental Research Letters.
Food consumption has traditionally been measured by questionnaires that require respondents to recall what they ate over the previous 24 hours, to keep detailed consumption records over a three-to-four-day period, or to indicate their typical consumption patterns over one-week to one-month periods. Because these methods ask for participants to report behaviors over extended periods of t

Your morning cereal or oatmeal. The bread on your sandwich. The corn chips for your snack, and the cookies for dessert. Not one would be possible with the humblest of ingredients: the seed.
Seeds such as wheat, rice and corn directly provide about 70% of the calories eaten by people every day. And they ultimately provide nearly every morsel of food, either by providing feed for livestock or by being grown into fruits and vegetables. It s no overstatement to say that without seeds, civilization would be impossible.

Scientists have discovered a never-before-seen biodiversity pattern of coral reef fishes that suggests some fishes might be exceptionally vulnerable to environmental change.
A new study shows plankton-eating coral reef fishes (planktivores) are far more diverse than others in the Indo-Australian Archipelago, a global marine biodiversity hotspot.
The findings highlight, for the first time, a unique link between the diet and distribution of species across the marine realm. The archipelago is one of the most complex and dynamic geological regions in the tropics, said lead author Dr Ale Siqueira from the ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral CoE at JCU). And its fishes underpin its status as a biodiversity hots
