While silicon has been the go-to material for sensor applications, could polymer be used as a suitable substitute since silicon has always lacked flexibility to be used in specific applications? This is what a recent grant from the National Science Foundation hopes to address, as Dr. Elsa Reichmanis of Lehigh University was recently awarded $550,000 to investigate how polymers could potentially be used as semiconductors for sensor applications, including Internet of Things, healthcare, and environmental applications.

“We’ll be creating the polymers that could be the building blocks of future sensors,” said Dr. Reichmanis, who is an Anderson Chair in Chemical Engineering in the Department of Chemical and Biomolecular Engineering at Lehigh University. “The systems we’re looking at have the ability to interact with ions and transport ionic charges, and in the right environment, conduct electronic charges.”

A joint team of physicists from Skoltech, MIPT, and ITMO developed an optical component that helps manage the properties of a terahertz beam and split it into several channels. The new device can be used as a modulator and generator of terahertz vortex beams in medicine, 6G communications, and microscopy. The paper appears in the journal Advanced Optical Materials.

Elon Musk traveled to Bali this weekend to officially launch Starlink, the SpaceX satellite internet service, in Indonesia this Sunday.

At a launch event with ministers in a health clinic in Indonesia, Musk stressed the significance of providing internet access to far-reaching corners of the vast archipelago, comprised of 17,000 islands across three time zones.

Experiments in Netherlands, China, and US demonstrate how qubits can be stored in ‘quantum memory’ and transmitted via fiber optics.

Researchers have developed a new communication paradigm that can let them securely connect a PC to a quantum computer over the internet.

Known as “blind quantum computing,” the technique uses a fiber-optic cable to connect a quantum computer with a photon-detecting device and uses quantum memory — the equivalent of conventional computing memory for quantum computers. This device is connected directly to a PC, which can then perform operations on the quantum computer remotely. The details were outlined in a new study published April 10 in the journal Physical Review Letters.

Earlier this month, Reddit published a Public Content Policy stating: Unfortunately, we see more and more commercial entities using unauthorized access or misusing authorized access to collect public data in bulk, including Reddit public content. Worse, these entities perceive they have no limitation on their usage of that data, and they do so with no regard for user rights or privacy, ignoring reasonable legal, safety, and user removal requests.

In its blog post on Thursday, Reddit said that deals like OpenAI’s are part of an open Internet. It added that part of being open means Reddit content needs to be accessible to those fostering human learning and researching ways to build community, belonging, and empowerment online.

Reddit has been vocal about its interest in pursuing data licensing deals as a core part of its business. Its building of AI partnerships sparks discourse around the use of user-generated content to fuel AI models without users being compensated and some potentially not considering that their social media posts would be used this way. OpenAI and Stack Overflow faced pushback earlier this month when integrating Stack Overflow content with ChatGPT. Some of Stack Overflow’s user community responded by sabotaging their own posts.

Experiments generate quantum entanglement over optical fibres across three real cities, marking progress towards networks that could have revolutionary applications.

The quest for perfect connectivity has taken a giant leap forward.

If you use the web for more than just browsing (that’s pretty much everyone), chances are you’ve had your fair share of “CAPTCHA rage,” the frustration stemming from trying to discern a marginally legible string of letters aimed at verifying that you are a human. CAPTCHA, which stands for “Completely Automated Public Turing test to tell Computers and Humans Apart,” was introduced to the Internet a decade ago and has seen widespread adoption in various forms — whether using letters, sounds, math equations, or images — even as complaints about their use continue.

A large-scale Stanford study a few years ago concluded that “CAPTCHAs are often difficult for humans.” It has also been reported that around 1 in 5 visitors will leave a website rather than complete a CAPTCHA.
