Today’s virtual reality systems can create immersive visual experiences, but seldom do they enable users to feel anything—particularly walls, appliances and furniture. A new device developed at Carnegie Mellon University, however, uses multiple strings attached to the hand and fingers to simulate the feel of obstacles and heavy objects.

By locking the strings when the user’s hand is near a virtual wall, for instance, the device simulates the sense of touching the wall. Similarly, the string mechanism enables people to feel the contours of a virtual sculpture, sense resistance when they push on a piece of furniture or even give a high five to a virtual character.

Scientists have — for the first time — shown how chemical triggers in the nervous system can amplify the pain experienced by mammals in response to certain stimuli.

The pain system probably evolved to alert them to life-threatening dangers. As they approach objects that are extremely hot or cold or are biting them, they experience intense pain — allowing them to get out of harm’s way.

But in certain diseases, that defence mechanism malfunctions and rather than providing a short, sharp shock — it produces long-term, chronic pain, seen with some conditions affecting humans such as neuropathies, arthritic pains or migraines.

Lucid in the sky.

With the curve finally flattening in the US, the ramping up of anti-viral and vaccine trials against SARS-CoV-2—the virus that causes Covid-19—and the launch of antibody tests to screen for previous infection, it seems like science is rapidly moving towards the end game. How exactly the Covid-19 pandemic will finally bugger off into history is still anyone’s guess, but virologists and public health experts generally agree that immunity is key—either through widespread safe and effective vaccination, or when enough of our population has recovered from infections and gained herd immunity.

Well. That’s the hand-waving, shruggie emoji, “eh who knows” short answer.

Like most processes in biology, immunity to SARS-CoV-2 is complex and mysterious, with results that could rapidly diverge into many possible futures. It’s partly why estimates of how long Covid-19 sticks around to wreak havoc can vary enormously, from months to years to…well, seasonal and forever, similar to the flu.

A full payout for Musk, who is also the majority owner and CEO of the SpaceX rocket maker, would surpass anything previously granted to US executives.

When Tesla unveiled Musk’s package in 2018, it said he could theoretically reap as much as $US55.8 billion if no new shares were issued. However, Tesla has since issued shares to compensate employees, and last year it sold $US2.7 billion in shares and convertible bonds.

The potential payout for Musk comes after Tesla said this month it would furlough all non-essential workers and implement salary cuts during a shutdown of its US production facilities because of the coronavirus outbreak. The pandemic has slashed US demand for cars and forced several other automakers to also furlough US workers.
