Light-matter interaction without interference

Quantum dots might constitute the foundation of quantum communication. They are an efficient interface between matter and light, with photons emitted by the quantum dots transporting information across large distances. However, structures form by default during the manufacture of quantum dots that interfere with communication. Researchers have now successfully eliminated these interferences.

A novel technology for genome-editing a broad range of mutations in live organisms

Researchers have developed a new tool — dubbed SATI — to edit the mouse genome, enabling the team to target a broad range of mutations and cell types. The new genome-editing technology could be expanded for use in a broad range of gene mutation conditions such as Huntington’s disease and the rare premature aging syndrome, progeria.

Tech time not to blame for teens’ mental health problems

A new study suggests that the time adolescents are spending on their phones and online is not that bad. The study tracked young adolescents on their smartphones to test whether more time spent using digital technology was linked to worse mental health outcomes.

Children of incarcerated parents have more substance abuse, anxiety

Children of incarcerated parents are six times more likely to develop a substance use disorder in adulthood and nearly twice as likely to have diagnosable anxiety compared to children whose parents were not incarcerated, according to new research.

Brain’s astrocytes play starring role in long-term memory

Researchers have discovered that star-shaped cells called astrocytes help the brain establish long-lasting memories. The work could inform therapies for disorders in which long-term memory is impaired, such as traumatic brain injury or dementia.
