The last complete reversal of the Earth's magnetic field took place 42,000 years ago. Radiocarbon analyses of the remains of kauri trees from New Zealand now make it possible for the first time to precisely time and analyze this event and its associated effects, as well as to calibrate geological archives such as sediment and ice cores from this period.

The gut microbiome is an integral component of the body, but its importance in the human aging process was unclear. Now, researchers 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.

Cancer researcher Rita Fior uses zebrafish to study human cancer. The basic principle of this approach relies on transplanting human cancer cells into zebrafish larvae. The fish then serve as "living test tubes" where treatments can be tested to reveal which are most effective.

Researchers were able to boost anti-tumor responses by creating white blood cell "super soldiers" in a series of experiments.

Using a novel 3D microscopy analysis technique, researchers have been able to create a comprehensive picture of human glioblastoma. This new information will help to identify therapeutic targets and develop immunotherapeutic strategies to combat this aggressive type of cancer.

A research group has tracked changes in the pancreas’s proteome — its complete set of proteins — from before birth through late adulthood.

The findings of a new study challenge the prevailing thinking on the primary role of serotonin and other neurotransmitters in the effects of antidepressants.

A study has identified that 11-year-old boys who play video games regularly are less like to have depression symptoms three years later.

Social media talk about game-piece colors could lead to misunderstandings, at least for hate-speech detection software.
