Watch Out for Upgrades for Model 3 in July.

Tesla Model 3 with dual motor now planned for July, says Elon Musk

Tesla officially planned to release the Model 3 with dual motor all-wheel-drive in "mid-2018" and we have recently seen several signs that the new version of the vehicle is coming. Now CEO Elon Musk linked the release of the new Model 3 powertrain with the automaker achieving a production rate of 5,000 Model 3 vehicles per week, which he now expects to hit in July.

 From article, (Tesla officially planned to release the Model 3 with dual motor all-wheel-drive in “mid-2018” and we have recently seen several signs that the new version of the vehicle is coming.

Now CEO Elon Musk linked the release of the new Model 3 powertrain with the automaker achieving a production rate of 5,000 Model 3 vehicles per week, which he now expects to hit in July.

The CEO also linked the timing with the release of the Model 3 white interior. Tesla currently only offers a single interior option with black upholstery.

The dual motor Model 3 is expected to deliver a slightly longer range and offer a quicker acceleration than the current single motor rear-wheel-drive version.

Last week, Tesla confirmed that they are now producing about 2,000 Model 3 vehicles per week.

What is most interesting here is that it implies Tesla expects to be able to produce and deliver up to 5,000 Model 3 vehicles per week with a single configuration.

The Model 3 is currently only offered with a rear-wheel-drive motor and ‘Long Range’ battery pack.

The standard battery pack and the dual motor configurations are expected to be quite popular and represent a significant part of the overall orders from reservation holders.

Yet, Tesla appears to expect to have enough orders for the RWD Long Range Model 3 over the next few months to produce several thousand Model 3 vehicles per week over that period of time.)

It Still Needs to be Tested on Humans, to See if it is a Cure for Hearing Loss, But It is Closer Than Researchers Have Been in Years

Huge breakthrough could cure hearing loss

In a stunning new development, scientists from the University of California may have found an innovative new way to treat hearing loss, a problem that affects millions of people and two thirds of people over 70 years of age. The discovery could eliminate the need for hearing aids and other devices for those who struggle with hearing.

 From article, (Researchers at USC and Harvard have developed a new approach to repair cells deep inside the ear — a potential remedy that could restore hearing for millions of elderly people and others who suffer hearing loss.

The lab study demonstrates a novel way for a drug to zero in on damaged nerves and cells inside the ear. It’s a potential remedy for a problem that afflicts two-thirds of people over 70 years and 17 percent of all adults in the United States.

“What’s new here is we figured out how to deliver a drug into the inner ear so it actually stays put and does what it’s supposed to do, and that’s novel,” said Charles E. McKenna, a corresponding author for the study and chemistry professor at USC Dornsife College of Letters, Arts and Sciences. “Inside this part of the ear, there’s fluid constantly flowing that would sweep dissolved drugs away, but our new approach addresses that problem. This is a first for hearing loss and the ear. It’s also important because it may be adaptable for other drugs that need to be applied within the inner ear.”

There are caveats. The research was conducted on animal tissues in a petri dish. It has not yet been tested in living animals or humans. Yet, the researchers are hopeful given the similarities of cells and mechanisms involved. McKenna says since the technique works in the laboratory, the findings provide “strong preliminary evidence” it could work in living creatures. They are already planning the next phase involving animals and hearing loss.

The study breaks new ground because researchers developed a novel drug-delivery method. Specifically, it targets the cochlea, a snail-like structure in the inner ear where sensitive cells convey sound to the brain. Hearing loss occurs due to aging, working with noisy machines and too many loud concerts. Over time, hair-like sensory cells and bundles of neurons that transmit their vibrations break down, as do ribbon-like synapses, which connect the cells.

The researchers designed a molecule combining 7,8-dihydroxyflavone, which mimics a protein critical for development and function of the nervous system, and bisphosphonate, a type of drug that sticks to bones. The pairing of the two delivered the breakthrough solution, the researchers said, as neurons responded to the molecule, regenerating synapses in mouse ear tissue that led to repair of the hair cells and neurons, which are essential to hearing.

“We’re not saying it’s a cure for hearing loss,” McKenna said. “It’s a proof of principle for a new approach that’s extremely promising. It’s an important step that offers a lot of hope.”)
