Medical Xpress / New ALS treatment target identified: STAUFEN-1 protein reduction protects brain cells from death

University of Utah researchers at the Pulst-Scoles Laboratory have discovered that reducing levels of the STAUFEN-1 protein can prevent neuron death caused by DNA damage and p53 activation in neurodegenerative diseases.

Phys.org / New spectroscopic method reveals ion's complex nuclear structure

Different atoms and ions possess characteristic energy levels. Like a fingerprint, they are unique for each species. Among them, the atomic ion 173Yb+ has attracted growing interest because of its particularly rich energy ...

Medical Xpress / Altered microbiome: Oral bacteria play a role in chronic liver disease, study reveals

Each year, more than two million people die from advanced chronic liver disease (ACLD). Previous research has linked gut microbiome disruptions to this condition and suggested that bacteria typically found in the mouth may ...

Phys.org / Comprehensive map reveals how E3 ligases organize protein cleanup in human cells

Maintaining cellular order is a major logistical challenge: Individual mammalian cells contain billions of protein molecules, which must be synthesized, deployed, and removed with precision. In the ubiquitin-proteasome system ...
