When sound waves reach the inner ear, neurons there pick up the vibrations and alert the brain. Encoded in their signals is a wealth of information that enables us to follow conversations, recognize familiar voices, appreciate music, and quickly locate a ringing phone or crying baby.
Neurons send signals by emitting spikes—brief changes in voltage that propagate along nerve fibers, also known as action potentials. Remarkably, auditory neurons can fire hundreds of spikes per second, and time their spikes with exquisite precision to match the oscillations of incoming sound waves.
With powerful new models of human hearing, scientists at MIT’s McGovern Institute for Brain Research have determined that this precise timing is vital for some of the most important ways we make sense of auditory information, including recognizing voices and localizing sounds.
Microsoft has shed light on a now-patched security flaw impacting Apple macOS that, if successfully exploited, could have allowed an attacker running as “root” to bypass the operating system’s System Integrity Protection (SIP) and install malicious kernel drivers by loading third-party kernel extensions.
The vulnerability in question is CVE-2024–44243 (CVSS score: 5.5), a medium-severity bug that was addressed by Apple as part of macOS Sequoia 15.2 released last month. The iPhone maker described it as a “configuration issue” that could permit a malicious app to modify protected parts of the file system.
“Bypassing SIP could lead to serious consequences, such as increasing the potential for attackers and malware authors to successfully install rootkits, create persistent malware, bypass Transparency, Consent and Control (TCC), and expand the attack surface for additional techniques and exploits,” Jonathan Bar Or of the Microsoft Threat Intelligence team said.
Bill Gates worries that kids today may miss out on a key advantage he had. The billionaire credits his successful career, in part, to having the freedom, and free time, in his youth to explore the world around him, to read and to think deeply without more modern distractions like smartphones and social media.
Today’s kids spend less time outside, exploring and playing with friends, than previous generations, thanks to the ubiquity of smartphones and social media.
That switch from a “play-based childhood” to one that’s “phone-based” has triggered a cultural shift that’s behind rising rates of mental health issues in younger generations, along with other negative effects on kids’ ability to learn and socialize, according to social psychologist Jonathan Haidt’s 2024 best-selling book “The Anxious Generation.”
Imagine a future where your phone, computer or even a tiny wearable device can think and learn like the human brain—processing information faster, smarter and using less energy.
A new approach developed at Flinders University and UNSW Sydney brings this vision closer to reality by electrically “twisting” a single nanoscale ferroelectric domain wall.
The domain walls are almost invisible, extremely tiny (1–10 nm) boundaries that naturally arise or can even be injected or erased inside special insulating crystals called ferroelectrics. The domain walls inside these crystals separate regions with different bound charge orientations.
Nokia’s Transparent 5g Smartphone: In a bold move that could redefine smartphone aesthetics, Nokia is preparing to launch an innovative transparent smartphone in the Indian market. This ambitious device promises to combine cutting-edge camera technology, robust battery life, and revolutionary design elements that could set new standards in the mobile industry. Let’s delve into what makes this upcoming device particularly noteworthy in today’s crowded smartphone landscape.
Revolutionary Design Philosophy
A team of metallurgists and geochemists at Guangzhou Institute of Geochemistry, working with a mechanical engineer from the Chinese Academy of Sciences, has improved their previous electrokinetic mining technique by scaling it up to industrial levels. In their paper published in Nature Sustainability, the group describes the changes they made to their system, and the results of testing they conducted at a mine.
Modern technology is reliant on multiple rare earth elements —they are used in EVs, smartphones and computers, for example. Unfortunately, mining such elements is extremely environmentally unfriendly. Huge machines are used to dig dirt and rock from large mines, where it is mixed with water and a host of toxic chemicals in order to extract the desired elements.
The process produces thousands of metric tons of toxic waste. The team in China has been working for several years to develop a cleaner way to extract the elements. It involves generating an electric field underground that coaxes the desired elements closer together and concentrates them, making for a much easier and cleaner separation process.
“Nowadays we always have our mobile phones or a flashlight, but to see bioluminescence in the forest, it has to be pitch black,” said Rudolf.
They collected some samples of the glowing specimen, originally thinking it was a known bioluminescent species called Mycena haematopus. In their well-lit studio, the artists realized that it was another species called the saffron drop bonnet mushroom (Mycena crocata). While this mushroom is known for its saffron-coloured milk, it had not previously been described as bioluminescent.
