Tesla has confirmed a new Model 3 Performance configuration is coming, but the big questions of when it is and what changes it will have remain up in the air.

Early in 2024, Tesla removed the Performance configuration from the Model 3’s list of available trims. It was the most expensive of the three Model 3 offerings, but it still qualified for the EV Tax Credit.

With the rollout of the new Model 3 ‘Highland’ globally, Tesla has not yet finalized a Performance version of the vehicle. Currently, it only offers two variants: the Rear-Wheel-Drive and Long Range.

In a new study published in Science today, JILA and NIST (National Institute of Standards and Technology) Fellow Jun Ye and his research team have taken a significant step in understanding the intricate and collective light-atom interactions within atomic clocks, the most precise clocks in the universe.

Using a cubic lattice, the researchers measured specific energy shifts within the array of strontium-87 atoms due to dipole-dipole interactions. With a high density of atoms, these mHz-level frequency shifts—known as cooperative Lamb shifts—were spectroscopically studied. These shifts were studied spatially and compared with calculated values using imaging spectroscopy techniques developed in this experiment.

These cooperative Lamb shifts, named because the presence of many identical atoms in a tightly confining space modifies the electromagnetic mode structure around them, are an important factor as the numbers of atoms in clocks continue to grow.

A team of researchers from Tohoku University and Okinawa Institute of Science and Technology (OIST) has achieved significant advancement in the field of microfluidics, allowing for precise and efficient manipulation of fluids in three-dimensional microscale environments. This work opens up new possibilities for bioanalytical applications, such as cell separations in the realm of medical diagnostics.

Details of their breakthrough were published in the journal Microsystems & Nanoengineering on January 22, 2024.

Microfluidic devices are designed to handle minuscule fluid volumes, allowing researchers to perform analyses and processes with remarkable precision and efficiency.

Two tech titans are now duking it out in the headset wars. Apple’s Vision Pro and Meta’s Quests offer different price points, different specs, and most importantly, different visions of the future of virtual reality. And both have big hurdles to clear. This week on TechCheck, why the headset battle is Apple’s to lose.
