The origin and legacy of the Etruscans

A recent study using genome-wide data from 82 ancient individuals in central and southern Italy has clarified the origins of the enigmatic Etruscans. The results show that despite their unique cultural expressions, the Etruscans were closely related to their Italic neighbors, with genetic transformations associated with historical events.

New imaging method for the detection of gastric lymphomas

A new imaging technique using PET/MR and a PET tracer directed against CXCR4 shows high accuracy in detecting MALT lymphomas of the stomach, potentially reducing the need for repeated gastroscopies.

Living with spinal cord injury: Resilience leads to better health outcomes

Research by James Krause and his team has shown that people with spinal cord injuries who develop resilience tend to have better health outcomes and live longer. This resilience allows them to adapt and thrive in the face of difficult circumstances, including neuropathic pain and feelings of isolation.

Decoding human history with ancient DNA

Ancient DNA research has revealed multiple waves of introgression between archaic humans and modern humans, as well as genetic continuity with present-day populations. Genetic data support an origin of early modern humans in Africa, while Eurasian populations show several early human lineages.

New landslides on US West Coast detected by SMU scientists

Researchers detected over 600 slow-moving landslides in western US states using satellite radar imagery. Most were in mountain ranges, near towns and roads, with some at risk of shifting due to earthquakes or rainfall. Landslides cause thousands of deaths worldwide each year.

Guiding microbes along their path

Researchers found that microbes exhibit highly organized and symmetrical movement patterns in response to interface curvature. The strength of the flux depends on the curvature, enabling the prediction of microbial navigation behavior.

In a gene tied to growth, scientists see glimmers of human history

Researchers have identified a shortened version of the human growth hormone receptor gene, GHRd3, which may help people survive in situations where resources are scarce or unpredictable. The study found that this variant emerged around 1-2 million years ago and was more prevalent in ancient humans and Neanderthals.
