New protocol counteracts the limitation of decoherence

The qubit state decays toward the “north pole” of the sphere due to decoherence. Using the study’s coherence-stabilized sensing protocol, the researchers temporarily counteracted the decay, leading to a larger…

How synthetic biology is producing greener chemicals, climate-resilient agriculture and repurposing food waste

Since the development of recombinant DNA technology 50 years ago – pioneered here at Stanford – we’ve seen the rise of breakthrough therapeutics that have transformed countless lives. What, then,…

The Psychology Behind Why Some People Give More Than Others

Summary: A new analysis of over 90,000 participants shows that personality traits influence how people engage in volunteering and charitable giving. Researchers found that extraverts are more likely to volunteer,…

Pre-war Jewish district uncovered in Lublin

Archaeologists from the Lublin Voivodeship Conservator of Monuments have uncovered traces of Lublin’s pre-war Jewish district during construction works at Zamkowa and Podwale streets. During the 16th century, Lublin was…

Smart surfaces could represent a powerless solution to multipath signal interference

Dopamine Signals Teach the Brain to Unlearn Fear

Summary: A new study reveals that dopamine release along a specific brain circuit helps extinguish fear by activating reward-related neurons in the amygdala. Researchers showed that dopamine from the ventral…

Dual scalable annealing processors overcome capacity and precision limits

The proposed system enables simultaneous expansion of the number of spins and interaction bit width using multiple identical LSI chips, resulting in more accurate and efficient solutions for combinatorial optimization…
