First large-scale stem cell bank created to investigate Alzheimer’s genetic risk factors

Alzheimer's disease (AD) is a common, debilitating neurodegenerative disease affecting about 10 percent of people over the age of 65 and one third of people aged 85 and above. Besides environmental factors, the genes have a strong influence on whether or not a person develops AD during their lifetime.

Restoring neuron balance in the amygdala reverses anxiety in mice

The Synaptic Physiology laboratory, led by Juan Lerma at the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and Miguel Hernández University (UMH) of Elche, has discovered that a specific group of neurons in the amygdala, a brain region involved in emotion regulation, plays a key role in the emergence of conditions such as anxiety, depression, and altered social behavior.

What’s behind the rising accident risk for Americans overseas?

Over the past two decades, US citizens traveling abroad have become relatively more likely to die from vehicular and non-vehicular accidents, even as absolute fatalities declined. Rising proportional mortality ratios highlight persistent regional risks, especially in lower-income destinations.

The clever ways Neanderthals got their fat long before modern humans

Neanderthals at Neumark-Nord, Germany, systematically transported and processed the bones of at least 172 large mammals to extract nutrient-rich "bone grease" nearly 125,000 years ago. This finding rewrites the timeline for large-scale fat processing, revealing unexpectedly complex resource strategies among Neanderthals.

EU researchers call for wider use of alternatives to animal testing

Researchers examine how the use of animal testing to identify endocrine-disrupting substances in the EU can be reduced. Although it is, in principle, possible to identify such substances without using animals, non-animal methods are still rarely applied.
