<p>What did an ancient Chinese emperor from 1,500 years ago look like? A team of researchers reconstructed the face of Chinese Emperor Wu of Northern Zhou using DNA extracted from his remains. The study, published March 28 in the journal <em>Current Biology</em>, suggests the emperor&rsquo;s death at the age of 36 might be linked to a stroke. It also sheds light on the origin and migration patterns of a nomadic empire that once ruled parts of northeastern Asia.</p>

<p>From pacemakers to neurostimulators, implantable medical devices rely on batteries to keep the heart on beat and dampen pain. But batteries eventually run low and require invasive surgeries to replace. To address these challenges, researchers in China devised an implantable battery that runs on oxygen in the body. The study, published March 27 in the journal <em>Chem</em>, shows in rats that the proof-of-concept design can deliver stable power and is compatible with the biological system.</p>

Gut microbe metabolite 2MBC worsens blood clot risk in COVID-19 patients, highlighting a potential causal link.

Researchers decode mouse neural activity to determine location and direction, aiding AI navigation without GPS.

<p>Researchers have paired a deep learning model with experimental data to &ldquo;decode&rdquo; mouse neural activity. Using the method, they can accurately determine where a mouse is located within an open environment and which direction it is facing, just by looking at its neural firing patterns. Being able to decode neural activity could provide insight into the function and behavior of individual neurons or even entire brain regions. These findings, publishing February 22 in <em>Biophysical Journal</em>, could also inform the design of intelligent machines that cu...
