Who is telling the truth about their health?

When researchers or policymakers ask health related questions — which they do a lot — they often rely on self-reported rather than tested health data. Researchers looked into how reliable this type of data is for research and found that, depending on country or age, self-reported data could be highly biased.

Research maps key signaling pathways linking calcium entry and exit in activated T cells

Like entrance and exit doors on a building, a cell's outer surface has doors — channels, pumps, and transporters that selectively control what molecules enter or exit. In the immune system, T cells possess unique sets of 'doors', including ones that specialize in calcium ion movement. Now, researchers describe a unique mechanism for coordinating these calcium entrance and exit 'doors' on T cells that helps them carry out their jobs and ensure normal immune function.

DNA metabarcoding useful for analyzing human diet

A new study demonstrates that DNA metabarcoding provides a promising new method for tracking human plant intake, suggesting that similar approaches could be used to characterize the animal and fungal components of human diets. The study demonstrated that dietary plant DNA can be amplified and sequenced from human stool using methods commonly applied to wildlife studies.

Engineers develop thin, lightweight lens that could produce slimmer camera phones, longer-flying drones

Electrical and computer engineering researchers have developed a new kind of optical lens that is much thinner and lighter than conventional camera lenses that also works with night imaging, a future boon for smartphones that could flatten those unsightly 'camera bumps' as well as for drones and night vision cameras for soldiers.
