How to fix Wi-Fi 6 problems on Mac mini by splitting your SSID
There can be many reasons why your Mac isn't connecting to Wi-Fi properly, but some issues can be fixed by altering your router's 2.4GHz and 5GHz settings.That's not someone crossing their fingers that the W-Fi is workingA small number of M2 Mac mini.....»»
NHTSA opens probe into nearly 87,000 Kia Tellurides after reports of high-beam failure
NHTSA's Office of Defects Investigation said it has received 23 complaints alleging a complete loss of high beams with no reengagement in 2020 Kia Telluride large crossovers......»»
Topological acoustic waveguide to help reduce unwanted energy consumption in electronics
A team of researchers has developed a new acoustic waveguide based on the mathematical concept of topology, which will lead to reduced energy consumption in many everyday electronic devices......»»
Researchers derive a unified topological speed limit for the evolution of physical states
Physical systems evolve at a particular speed, which depends on various factors including the system's so-called topological structure (i.e., spatial properties that are preserved over time despite any physical changes that occur). Existing methods f.....»»
Photonic hopfions: Light shaped as a smoke ring that behaves like a particle
We can frequently find in our daily lives a localized wave structure that maintains its shape upon propagation—picture a smoke ring flying in the air. Similar stable structures have been studied in various research fields and can be found in magnet.....»»
Innolux liquid crystal extraction process reduces procurement expenses by US$14 million
TFT-LCD panel maker Innolux has undertaken zero-waste and zero-pollution automation of its liquid crystal extraction process, according to the company......»»
Definite spectroscopic evidence for magnetic reconnection in splitting of solar filament structure
Magnetic reconnection is a universal process that changes magnetic topology and converts magnetic energy to plasma kinetic energy. Spatially resolved spectroscopic observations covering extended regions in the solar atmosphere are rare, and thus the.....»»
New optical method to verify topological phases in magnetic materials
Topological phases are not restricted to electronic systems. They can also occur in magnetic materials whose properties are described in terms of magnetic waves—or so-called magnons. However, even though scientists have established techniques to ge.....»»

Scientists achieve phonon and photon lasing in optomechanical cavities
Since the introduction of the first ruby laser—a solid-state laser that uses the synthetic ruby crystal as its laser medium—in 1960, the use of lasers has expanded significantly in scientific, medical and industrial fields......»»
Apple Music exec adds Apple TV+ to responsibilities amid Services leadership reshuffle
Following the surprise departure of Apple Services VP Peter Stern, Apple is reorganizing the expansive Services division by formally splitting the business into three separate units, with a new VP running each group. The VPs will report to Eddy Cue,.....»»
Deep-ultraviolet birefringent hydrogel based on 2D cobalt-doped titanate
A birefringence based light modulator that works in the wavelength region of < 350 nm plays a vital role in DUV beam shaping, high density data storage, semiconductor micro-nano processing and photolithography. Actually, a series of DUV birefringent.....»»
Apple"s Music & TV apps hit Windows - but only Windows 11
Apple has quietly released PC apps for Apple Music and TV — but the new apps will not run on the near ubiquitous Windows 10.Apple replaced iTunes for Mac users in 2019, splitting its functions out into separate apps for Apple Music, Apple TV+, and.....»»
Researchers create an optical tractor beam that pulls macroscopic objects
Researchers have developed a way to use laser light to pull a macroscopic object. Although microscopic optical tractor beams have been demonstrated before, this is one of the first times that laser pulling has been used on larger objects......»»
Razer Blade 16 vs. Razer Blade 15: here’s how they stack up
Razer has dominated the 15-inch laptop space with the Blade 15, which has been fast and highly configurable. But the Blade 16 looks to take over the top spot......»»
