Security experts from paluno, the Ruhr Institute for Software Technology at the University of Duisburg-Essen (UDE) have developed a new technique that, for the first time, enables fuzz testing of protected memory areas in modern processors. Their method revealed many vulnerabilities in security-critical software.

Intel’s “Software Guard Extension” (SGX) is a widely used technology to protect sensitive data from misuse. It helps developers in shielding a certain memory area from the rest of a computer. A password manager, for example, can be executed safely in such an enclave, even if the rest of the system is corrupted by malware.

However, it is not uncommon for errors to creep in during the programming of the enclaves. Already in 2020, the paluno team from Prof. Dr. Lucas Davi discovered and published several vulnerabilities in SGX enclaves. Now, together with partners form the CASA cluster of excellence, the researchers have achieved another breakthrough in the analysis techniques: Their latest development enables the fuzz testing of enclaves, which is much more effective than the previously used symbolic execution. The idea behind fuzz testing is to feed a large number of inputs into a program in order to gain insights into the structure of the code.

Scientists have created an artificial intelligence that is able to think and learn like a baby.

The system is able to grasp the basic common sense rules of the world in the same way as humans can, the researchers who create it say.

The breakthrough could not only help advance AI research but also the ways we understand the human mind, scientists say.

If you live near a river and want clean energy to power your home, we have great news for you. Belgian company Turbulent has created a fish-friendly whirlpool turbine that can be installed in only one week.

The innovative turbine can provide energy 24 hours a day for dozens of homes by being installed in most rivers and canals. It also delivers low-cost power as the generator just uses flowing water to produce energy.

Modern technology allows us to measure magnetic fields created by electric signals in our brains. Now, a breakthrough makes detection 10 times better.

Meta, the Facebook parent company, has announced its new, artificial intelligence (AI)-driven language translation model, which claims to be able to translate 200 languages worldwide, in real-time. In a blog post from earlier today, Meta said that this is the first AI language translator model that brings a large number of fringe and lesser known languages from around the world — including fringe dialects from Asia and Africa.

The AI model can also carry out these translations without needing to first translate a language to English, and then translate it to the originally intended language. This, Meta said, does not only help in speeding up the translation time, but is a breakthrough of sorts since many of the 200 languages that its AI model can understand had little to no available public data for AI to train on.

The initiative is part of the company’s No Language Left Behind (NLLB) project, which it announced in February this year. The new AI model, called NLLB-200, has achieved up to 44% higher BLEU (Bilingual Evaluation Understudy) score in terms of its accuracy and quality of translation results. For Indian dialects, NLLB-200 is 70% better than existing AI models.

“We just open-sourced an AI model we built that can translate across 200 different languages — many which aren’t supported by current translation systems,” he said. “We call this project No Language Left Behind, and the AI modeling techniques we used from NLLB are helping us make high quality translations on Facebook and Instagram for languages spoken by billions of people around the world.”

Meta invests heavily in AI research, with hubs of scientists across the globe building realistic avatars for use in virtual worlds and tools to reduce hate speech across its platforms 0, among many other weird and wonderful things. This investment allows the company to ensure it stays at the cutting edge of innovation by working with the top AI researchers, while also maintaining a link with the wider research community by open-sourcing projects such as No Languages Left Behind.

The major challenge in creating a translation model that will work across rarer languages is that the researchers have a much smaller pool of data — in this case examples of sentences — to train the model versus, say, English. In many cases, they had to find people who spoke those languages to help them provide the data, and then check that the translations were correct.

It may seem like technology advances year after year, as if by magic. But behind every incremental improvement and breakthrough revolution is a team of scientists and engineers hard at work.

UC Santa Barbara Professor Ben Mazin is developing precision optical sensors for telescopes and observatories. In a paper published in Physical Review Letters, he and his team improved the spectra resolution of their superconducting sensor, a major step in their ultimate goal: analyzing the composition of exoplanets.

“We were able to roughly double the spectral resolving power of our detectors,” said first author Nicholas Zobrist, a doctoral student in the Mazin Lab.

Our ability to create nano scale products is getting better fast, and these breakthroughs could transform every industry from manufacturing to healthcare and beyond.

Intel Labs has announced that it has made a noteworthy advancement in the area of integrated photonics research, which it bills as the “next frontier” in expanding communications bandwidth between compute silicon in data centers and across networks. The company believes this advancement holds the promise of a future input/output (I/O) interface with improved energy efficiency and bandwidth, and a longer reach.

The disclosure explains the possibility to obtain well-matched output power in conjunction with uniform and densely spaced wavelengths, according to Haisheng Rong, Senior Principal Engineer at Intel Labs. Rong also points out that this can be done by utilizing existing manufacturing and process techniques in Intel fabs, and therefore ensures a path to volume production of the “next-generation co-packaged optics and optical compute interconnect at scale.”

Intel states that this breakthrough results in industry-leading advancements in multiwavelength integrated optics. It includes the demonstration of an eight-wavelength distributed feedback (DFB) laser array that is fully integrated on a silicon wafer and provides exceptional output power uniformity of +/-0.25 decibel (db), as well as wavelength spacing uniformity of +/-6.5% that go beyond industry specifications.
