Q&A: How TikTok's 'black box' algorithm and design shape user behavior
2024-04-24 22:37:38
TikTok's swift ascension to the upper echelons of social media is often attributed to its recommendation algorithm, which predicts viewer preferences so acutely it's spawned a maxim: "The TikTok algorithm knows me better than I know myself." The platform's success was so pronounced that it has seemed to spur other social media platforms to shift their designs. When users scroll through X or Instagram, they now see more recommended posts from accounts they don't follow.

New insights lead to better next-gen solar cells
2024-04-24 21:34:21
For Michael Saliba and Mahdi Malekshahi, it was one of those moments in science when good experimental results raised more questions. The University of Stuttgart researchers recently developed a new process to make solar cells with perovskites—advanced crystalline materials with the potential to revolutionize solar technology. Their cells were very efficient and stable, but there was one catch: they did not have a detailed understanding of why this process worked so well.
Virtual sensors help aerial vehicles stay aloft when rotors fail
2024-04-24 21:10:57
No crystal ball is needed to envision a future that engineers have in mind, one in which air taxis and other flying vehicles ferry passengers between urban locations, avoiding the growing gridlock on the ground below. Companies are already prototyping and testing such hybrid electric "flying cars" that take off and land vertically but soar through the air like winged aircraft to enable efficient flight over longer distances.
New tech could help traveling VR gamers experience 'ludicrous speed' without motion sickness
2024-04-24 21:10:53
Vehicle passengers using VR headsets to pass the time during travel could be set to enjoy games which move at 'ludicrous speed' without experiencing motion sickness, researchers say.
Why can't robots outrun animals?
2024-04-24 21:10:53
Robotics engineers have worked for decades and invested many millions of research dollars in attempts to create a robot that can walk or run as well as an animal. And yet, it remains the case that many animals are capable of feats that would be impossible for robots that exist today.
High-energy-density capacitors with 2D nanomaterials could significantly enhance energy storage

2024-04-24 20:54:23
An ongoing research project at Tampere University aims to create adaptable safety systems for highly automated off-road mobile machinery to meet industry needs. Research has revealed critical gaps in compliance with legislation related to public safety when using mobile working machines controlled by artificial intelligence.
Students build low-cost cold spray metal 3D printer prototype
2024-04-24 20:54:22
A team of Rice University students has developed a cold spray metal 3D printing device that relies on pressure and velocity rather than temperature to create a metal part. Their work could help expand the repertoire of metal additive manufacturing techniques, bringing down cost and enhancing the quality of making or repairing one-off complex metal parts.
Child pedestrians, self-driving vehicles: What's the safest scenario for crossing the road?
2024-04-24 20:54:22
Crossing a busy street safely typically is a result of a social exchange. Pedestrians look for cues—a wave, a head nod, a winking flash of the headlights, and, of course, a full vehicle stop—to know it's safe to cross.
Rubber-like stretchable energy storage device fabricated with laser precision
2024-04-24 20:54:22
Researchers have achieved a significant breakthrough in developing a small-scale energy storage device capable of stretching, twisting, folding, and wrinkling. Their study is published in the journal npj Flexible Electronics.
