Even when it’s ground into microparticles, 97% of an algae-based plastic biodegrades in compost and water in under seven months, a new study has reported. The researchers hope their plastic will eventually replace existing petroleum-based ones, which have caused concern due to their effects on health and the environment.In recent years, there has been a great deal of chatter about – and research into – microplastics, the tiny, almost indestructible fragments shed from everyday plastic products. Much of that research has…

Neuralink CEO Elon Musk has reacted to a live stream of a quadriplegic man, the company's first brain implant patient, playing video games and online chess using just his mind.  In the video shared…

A breakthrough in nanocavity technology has been achieved by researchers, creating a III-V semiconductor nanocavity with unprecedented light confinement. This development is set to transform photonic devices, improving communication and computing efficiency.

In 1856, decades before the term “greenhouse gas” was coined, Eunice Newton Foote demonstrated the greenhouse effect in her home laboratory. She placed a glass cylinder full of carbon dioxide in sunlight and found that it heated up much more than a cylinder of ordinary air. Her conclusion: more carbon dioxide in the atmosphere results in a warmer planet. Several years later a Irish scientist named John Tyndall conducted a far more complicated experiment that demonstrated the same effect and revealed how it worked. Today…

New research in structured light means researchers can exploit the many patterns of light as an encoding alphabet without worrying about how noisy the channel is. Credit: Wits UniversityA new approach to optical communication that can be deployed with conventional technology.The patterns of light hold tremendous promise for a large encoding alphabet in optical communications, but progress is hindered by their susceptibility to distortion, such as in atmospheric turbulence or in bent optical fiber.  Now researchers at the…

The MIT D Lab-supported startup SurgiBox has developed a portable kit that doctors can use to create sterile operating environments in low-resource environments. The SurgiBox system includes a bubble with armholes facing inward, a module that filters and controls airflow, and a battery. The entire thing fits inside a backpack and can be set up in minutes.

Scientists have conducted an experiment that demonstrates the time reflection of electromagnetic waves, which has potential implications for wireless communications and optical computing.The discovery establishes the foundations for revolutionary applications in wireless communications and optical computing.When we look in a mirror, we are used to seeing our faces looking back at us. The reflected images are produced by electromagnetic light waves bouncing off of the mirrored surface, creating the common phenomenon called…

How GANs work and how you can use them to synthesize dataFig. 1 — Synthetic images of a person, generated entirely by a GAN. Image source: https://thispersondoesnotexist.com/ . License: https://github.com/lucidrains/stylegan2-pytorch/blob/master/LICENSE (MIT)If you’re working in deep learning, you’ve probably heard of GANs, or Generative Adversarial Networks (Goodfellow et al, 2014). In this post we will explain what GANs are, and discuss some use cases with real examples. I am adding to this post a link to my GAN…

Physicists have experimentally demonstrated for the first time that there is a negative correlation between the two spins of an entangled pair of electrons from a superconductor. Credit: Department of Physics, University of Basel, ScixelFor the first time, physicists have experimentally demonstrated that there is a negative correlation between the two spins of an entangled pair of electrons from a superconductor. For their study, the researchers used spin filters made of nanomagnets and quantum dots.Some phenomena in…
