A quantum harmonic oscillator—a structure that can control the location and energy of quantum particles that could, in the future, be used to develop new technologies including OLEDs and miniature lasers—has been made at room temperature by researchers led by the University of St Andrews.

The research, conducted in collaboration with scientists at Nanyang Technological University in Singapore and published in Nature Communications recently, used an organic semiconductor to produce polaritons, which show quantum states even at room temperature.

Polaritons are quantum mixtures of light and matter that are made by combining excitations in a semiconductor material with photons, the fundamental particles that form light. To create polaritons, the researchers trapped light in a thin layer of an organic semiconductor (the kind of light-emitting material used in OLED smartphone displays) 100 times thinner than a single human hair, sandwiched between two highly reflective mirrors.

This flaw, which has been identified that affects the ksmbd NTLMv2 authentication in the Linux kernel, is known to quickly cause the operating system on Linux-based computers to crash. Namjae Jeon is the developer of KSMBD, which is an open-source In-kernel CIFS/SMB3 server designed for the Linux Kernel. It is an implementation of the SMB/CIFS protocol in the kernel space that allows for the sharing of IPC services and files over a network.

In order to take advantage of the vulnerability, you will need to transmit corrupted packets to the server, personal computer, tablet, or smartphone that you are targeting. The attack causes what is known as “a memory overflow flaw in ksmbd decodentlmssp auth blob,” which states that nt len may be less than CIFS ENCPWD SIZE in some circumstances. Because of this, the blen parameter that is sent to ksmbd authntlmv2, which runs memcpy using blen on memory that was allocated by kmalloc(blen + CIFS CRYPTO KEY SIZE), is now negative. It is important to take note that the CIFS ENCPWD SIZE value is 16, and the CIFS CRYPTO KEY SIZE value is 8. As the heap overflow happens when blen is in the range [-8,-1], we think that the only possible outcome of this problem is a remote denial of service and not a privilege escalation or a remote code execution.

Broadcom will lose an order for millions of chips if Apple manages to have its own wireless chip ready in time for the iPhone 17.

Is AI coming for voice artists now?

Researchers at technology major Microsoft have unveiled their latest text-to-speech (TTS) generator, VALL-E that can be trained to mimic anybody’s voice in just three seconds. Unlike previous voice generators that sounded robotic, VALL-E sounds naturally human, and that may not be a very good thing.

Text-to-speech generators that gave voice to one of the greatest minds on the planet, Stephen Hawking, have come a long way. From reading messages on your smartphone to reading out pages from a book, these services are now everywhere and used by everyone.

It is also looking at a possible investment from Microsoft.

OpenAI, the artificial intelligence research company, is building an iOS app powered by its globally popular chatbot ChatGPT which helps users search for answers using an iMessage like interface. A beta version of the app is being tested currently, and a demo version was shared on the professional networking site LinkedIn.

Launched in November last year, ChatGPT made global news for its ease of answering even complex questions in a conversational manner. The algorithm that powers the chatbot, GPT3.5 is built by Open AI and is trained to learn what humans mean when they ask a question.

Google has warned that growth in the use of Android in India may stall due to an antitrust order issued by the Indian antitrust watchdog last year over the U.S. company’s domination in the country.

The order, which was issued by the Competition Commission of India (CCI) in September, found that Google had abused its dominant position in the market for mobile operating systems by imposing restrictive contracts on mobile manufacturers.

The CCI ordered Google to change its contracts with manufacturers, allowing them more freedom to install rival apps and services on Android devices. According to a Reuters report, Google filed a challenge with India’s Supreme Court and said that the order would require some modifications of its existing contracts and new license agreements. It would alter the company’s existing arrangements with over 1,100 device manufacturers and thousands of app developers.

Google announced a new HD version of its Maps service for cars with the Android Automotive operating system. The new HD maps will provide more detailed road markings, lane-level localization, road barriers and signs. The feature will debut on the Volvo EX90 and Polestar 3 models and will benefit from the lidar, radar and camera sensors on vehicles to ensure a safer driving experience.

Apple Maps launched a new parking feature that provides users with parking options and availability near a specific destination. In partnership with the digital parking reservation platform, SpotHero, Apple Maps users across the U.S. and Canada can now get parking information for over 8,000 locations.

To use the new feature, launched late last week, iPhone and Mac users can search for a destination in the Apple Maps app and then select “More” and “Parking.” They’re then directed to the SpotHero website without leaving Apple Maps. Users can search for nearby parking and reserve a space using SpotHero’s secure payment options, the parking platform claims.

SpotHero also allows users to filter their search by date and time as well as parking spots with EV charging, wheelchair accessibility, valet services and more.

Humans are eternally curious about the night sky, but figuring out how to use a telescope is non-trivial. At CES in Las Vegas, Unistellar believes it has the perfect solution with its Equinox 2 Smart Telescope.

“When I was a young teenager, I had a telescope that I used during the long summer nights. Fast forward to being an adult – I didn’t have any more time to do astronomy. With a friend of mine, we started to think about what we can do to bring astronomy back to our busy daily lives,” says Laurent Marfisi, co-founder and CEO of Unistellar in an interview with TechCrunch. “We thought up a telescope that is easy to use, that is powerful enough to see through the light pollution, and that has the possibility to reveal galaxies and nebulae, all those things that we could not see even when we were teenagers. The aim is to bring a lot of the power that professionals have in astronomy into the daily lives of consumers who just want to have fun, spend good quality time with their children and their friends around astronomy.”
