Abstract: Multi-objective evolutionary algorithms (MOEAs) have achieved notable success in recommendation systems (RSs) by meeting diverse user needs. However, existing MOEAs lack effective methods to ...

Researchers have built a tiny, lightweight microscope that captures neuron activity with unprecedented speed that can be used in freely moving animals. The new tool could give scientists a more ...

A new dual-light microscope lets researchers observe micro- and nanoscale activity inside living cells without using dyes. The system captures both detailed structures and tiny moving particles at ...

Gerard Baker proposes that “Biased Media Needs a Complete Culture Change” (Free Expression, Oct. 21). He’s half right: Journalists should amend their ways—by being honest about their biases. The ...

In quantum computing studies, precision optics play a pivotal role in experimental success. The long working distance (LWD) microscope objective lens is a key element in ion-trap quantum computers.

I built a 3D printed, scanning laser confocal microscope so I could collect 3D surface topology and profilometry data! The microscope stage is based on an OpenFlexure "Delta" stage, and the confocal ...

Over on YouTube [Applied Science] shows us how to make an f/0.38 camera lens using an oil immersion microscope objective. The f-number of a lens indicates how well it will perform in low-light. To ...

We installed a filter (cut with a utility knife) just beneath the white diffusive filter within the top Slot 10 seems like the best place for the microscope to go. Doesn't interfere with others.

Continuing our monthly interview series "Building a Free Internet of the Future", we spoke with the team behind the OpenFlexure open hardware microscope project, and in particular with Julian Stirling ...

Google entered the final stretch of an antitrust case targeting its digital advertising monopoly, weeks after emerging largely unscathed from a similar challenge to its online search stronghold. The ...
