Phys.org / Moonquakes could reveal ice buried beneath lunar south polar craters
Finding water on the moon may only be a matter of detecting the right vibrations.
Phys.org / Newly discovered mechanism protects DNA during cell division
Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However, in some cases, chromosomes do not fully separate, leaving behind thin strands of DNA known as DNA bridges that connect ...
Phys.org / Cretaceous beetle fossil reveals early evolution of firefly sensory and signaling systems
Scientists have discovered a remarkably well-preserved 100-million-year-old beetle fossil that provides a rare glimpse into the evolution of the intricate sensory and communication systems used by fireflies and their relatives ...
Phys.org / Homing in on the X-ray sky with eROSITA's second data release
The German eROSITA consortium (eROSITA-DE), which includes the University of Bonn and is led by the Max Planck Institute for Extraterrestrial Physics (MPE), has released its second major public data set, the "eROSITA Data ...
Phys.org / Magnetic nanoparticles remove forever chemicals from water
PFAS, otherwise known as forever chemicals, have become commonplace in numerous everyday and industrial products. At the same time, they are some of the most problematic pollutants of our times: They are extremely durable, ...
Phys.org / Shark finning regulations have not significantly changed global trade, new analysis finds
Much like caviar, shark fins are a luxury product and delicacy in parts of the world. And like wild caviar, demand for shark fins has posed an incredible threat to species that can't reproduce quickly enough to keep up.
Medical Xpress / Chromosome-protecting protein may help explain muscle repair and the rarity of muscle cancers
A protein best known for protecting the ends of chromosomes also helps muscle stem cells preserve their identity and repair damaged tissue, according to a new study from researchers at the Perelman School of Medicine at the ...
Phys.org / A backup fluoride defense in soil bacteria could aid greener chemical production
Researchers at the University of Tartu have discovered a mechanism in bacteria that helps them adapt to fluoride, which is toxic to most organisms above relatively low threshold concentrations. Their discovery may represent ...
Medical Xpress / Hyperuricemia predicts mortality with chronic kidney disease
Hyperuricemia independently predicts mortality in chronic kidney disease (CKD), according to a study published online July 13 in the Journal of Clinical Medicine.
Medical Xpress / Microglia reveal sex-specific brain recovery mechanism after ketamine anesthesia
During ketamine anesthesia, the brain's nerve cells fall silent—as consciousness returns, they begin to reconnect. For the first time, researchers at the Institute of Science and Technology Austria (ISTA) have shown that ...
Phys.org / Modified cell vesicles trigger 'lipid counterstorm' against lung inflammation in mice
The COVID-19 pandemic highlighted severe consequences of unchecked respiratory disease, including cytokine storms. This phenomenon affected many COVID-19 patients and is a potential side effect of many other diseases involving ...
Phys.org / Astronomers finally measure the full size of the largest known galaxy
Researchers have obtained the deepest images ever taken of IC 1101, allowing them to identify the galaxy's outer edge for the first time. The observations confirm it as the largest known galaxy, spanning roughly 520 kiloparsecs, ...
