Summaries

Extremely energy efficient microprocessor developed using superconductors

techxplore.com
  • To build ultra-low-power, high-performance microprocessors, researchers used adiabatic quantum-flux-parametron (AQFP), an energy-efficient superconductor.
  • It’s an attempt to build extremely energy-efficient electronics for the next generation of data centers and communication networks.
  • Their processors have roughly the same performance as current state-of-the-art, and they’d cost much less to run.
  • Even though they’d need to be kept in extremely low temperatures to work, they’d still be more energy efficient.

Individuals with depression show a lack of positive bias when it comes to autobiographical memory

psypost.org
  • The story we tell ourselves (autobiographical memory) can be a way to improve ourselves - or to destroy ourselves.
  • Study finds that people with depression are less likely to remember positive events from their life, and it doesn’t even help them to be reminded of them.
  • Depressed people view negative events as equally important to positive effects, whereas healthy people simply focus on the positive to create their self-image.
  • Which means that depressed people can’t benefit from positive Autobiographical Memory.
  • This keeps them from viewing themselves in any positive light, and perpetuates their negative self-image.

Desalination Breakthrough Could Lead to Cheaper Water Filtration

  • Removing salt from water has been a challenge for scientists for decades, and this new study might provide a way to make it easier.
  • Researchers found that membranes used to clean water in desalination technology are inconsistent - making them uniformly dense at the nanoscale can help.
  • This can improve membrane efficiency by 30-40%, making desalination cheaper.
  • Desalination is becoming more important every year, as more people struggle to get access to clean water.

The promise of conditional cash transfers

aeaweb.org
  • 6-year long study of Conditional Cash Transfers (CCT) finds that they improve the lives of children living in poverty in Indonesia.
  • The positive effects included better nutrition and greater access to healthcare for children in families that received CCTs.
  • The study provides guidelines for policymakers that want to implement similar programs, and it’s one of the first big studies of how CCTs improve lives.
  • CCTs are about providing poor, working families with money based on simple conditions (like children regularly attending school).

New Quantum Algorithms Finally Crack Nonlinear Equations

quantamagazine.org
  • We can’t predict the weather, among many other complex issues, because computers still can’t solve nonlinear equations.
  • But this might change soon, as two different research teams created algorithms that can be used for nonlinear modelling on quantum computers.
  • Their techniques still need refining, and won’t be real-world ready for years, but these studies are another stepping stone towards truly useful quantum algorithms.
