For $200,000, Tesla Will Sell You The 'World's Fastest' Consumer Car

Nov 18: Tesla's very first car is back. It's red. It's fast. And it will cost you upward of $200,000.

The Roadster, the electric sports car that put the automaker on the map, made a surprising appearance at Tesla's semi-truck event late Thursday. The next-generation Roadster is Tesla's first new sports car since it discontinued the original in 2012, and marks the company's bid to remain competitive across several categories in the world of electric vehicles that it helped reshape.

The updated Roadster will achieve world record speeds, Tesla chief executive Elon Musk said during the event in Los Angeles. The base model can travel from a dead stop to 60 miles per hour in less than two seconds, making it the fastest consumer car on the planet, and the first to break the two-second mark, Musk said. He declined to give the Roadster's top speed but said it would surpass 250 mph.

But while Musk and his audience were characteristically gleeful, investors and some auto analysts were skeptical about the company's prospects. Tesla's stock fell nearly four percent in midday trading Friday. Some industry observers pointed to the company's production delays in its mass-market Model 3. Ed Hellwig, a senior editor at auto research website Edmunds.com, described the Roadster as a "very unnecessary distraction" whose reintroduction was likely designed to divert attention from Tesla's business struggles.

The company reported a net loss of $619 million, or about $2.92 per share,in its most recent earnings report, compared with a net income of $21 million and a gain of 71 cents per share, during the same period last year. Tesla also said recently that it had fired hundreds of employees after annual performance reviews. And it's unclear, even as the company faces production bottlenecks, where the new Roadster will be manufactured.

Analysts said that it's too early to tell if the Roadster will help lift Tesla to profitability, but the sports car gives the company's image a boost. "You can say a lot of things about Tesla, but one thing it's done is built a brilliant brand," said Michelle Krebs, executive analyst at Autotrader.

The original Roadster, released nearly a decade ago, was Tesla's the first step in a multistage process to entice the public with its promising technology and eventually offer all-electric vehicles to the masses. The company showed that electric vehicles could preform just as well, and perhaps even better, than cars powered by fossil fuel. Its limited run, in Tesla's view, was part of the plan.

"We started Tesla with a sports car, the Tesla Roadster. That baby got us going. It was the foundation of the whole company," said Musk said. "People have asked us for a long time, 'When are you going to make a new roadster?' We are making it now."

The successor, like the original, was designed to make a splash. The unveiling itself was a surprise, coming after Musk showed off Tesla's long-anticipated semitruck. But beyond Musk's flair for showmanship, experts said the new Roadster gives Tesla a prestige product to showcase and compete with.

"It's got a lot of sizzle. It worked before, and why not," said Krebs. "If they get it on the roads it will be something that will go head-to-head with Porsches and Ferraris and all the exotic vehicles."

Toni Sacconaghi, an analyst at Bernstein Research, described the Roadster as a "brand enhancing," car, in a note to investors Friday. But he also said he sees it as a low-volume product. He cautioned that Tesla should focus on building and selling the economy-class Model 3, rather than broadening its initiatives with new vehicles and energy projects.

While experts did not go so far as to describe the Roadster as a game changer, they said it will allow Tesla to challenge automakers of high-end sports cars who have been nudged, largely by Tesla, to make high-powered electric vehicles of their own. Musk made that argument in more colorful language. "The point of doing this is to just give a hardcore smackdown to gasoline cars," he said. "Driving a gasoline sports car is going to feel like a steam engine with a side of quiche."

Tesla says the car will come with a 200-kilowatt-hour battery, giving it a range of 620 miles at highway speeds without the need to recharge. In comparison, the current 75-kilowatt-hour battery in the Model S gives the sedan a 250-mile range. To put the Roadster's battery endurance into perspective, Musk said a driver would be able to travel from Los Angeles to San Francisco, and back again, on a single charge.

Up to four people can fit in the Roadster with "plenty of storage," Musk said. But he was quick to add that you can't put "giant" people in the back seat. The car will feature all-wheel drive and will have three motors.

The first customers of the new Roadster will have to wait a few years before they can climb in and let the top down, however. Musk said the car will not be available until 2020. The "Founders Series" will go for $250,000, but its specifications won't be shared until as early as next year, Musk said.

Twitter has joined efforts to do away with racially loaded terms such as master, slave and blacklist from its coding language in the wake of the death of African-American George Floyd and ensuing Black Lives Matter protests.

The project started even before the current movement for racial justice escalated following the death of 46-year-old George Floyd in police custody in May.

The use of terms such as "master" and "slave" in programming language originated decades ago. While "master" is used to refer to the primary version of a code, "slave" refers to the replicas. Similarly, the term "Blacklist" is used to refer to items which are meant to be automatically denied.

The efforts to change these terms in favour of more inclusive language at Twitter were initiated by Regynald Augustin and Kevin Oliver and the microblogging platform is now backing their efforts.

"Inclusive language plays a critical role in fostering an environment where everyone belongs. At Twitter, the language we have been using in our code does not reflect our values as a company or represent the people we serve. We want to change that. #WordsMatter," Twitter's engineering team said in a post on Thursday.

As per the recommendations from the team, the term "whitelist" could be replaced by "allowlist" and "blacklist" by "denylist".

Similarly, "master/slave" could be replaced by "leader/follower", "primary/replica" or "primary/standby".

Twitter, however, is not the first to start a project to bring inclusivity in programming language.

According to a report in CNET, the team behind the Drupal online publishing software started using "primary/replica" in place of "master/slave" as early as in 2014.

The use of the terms "master/slave" was also dropped by developers of the Python programming language in 2018.

Now similar efforts are underway at Microsoft's Github and LinkedIn divisions as well, said the report.

The Brazilian government said that the Amazon rainforest witnessed deforestation of a record 829 sq km in May, the highest monthly level since 2015.

On Friday, the National Institute for Space Research (INPE) said that deforestation in the Amazon increased by 91 sq km compared to the same period last year, reports Xinhua news agency.

Between January and April, destruction of the forest by illegal loggers and ranchers rose 55 per cent, or a total of 1,202 sq km was wiped out, it said.

The Real-time Deforestation Detection system, a federal project created to monitor human activity in the Amazon, alerted authorities to the increase in the rate of destruction of the rainforest.

A recent study by the Amazon Environmental Research Institute (IPAM) warned that deforestation in 2020 could reach 11,900 sq km if the pace of May, June, and July follows the historical average.

Deforestation in the region has soared since President Jair Bolsonaro took office last year, according to conservation groups.

He has argued that more farming and mining in protected areas of the forest were the only way to lift the region out of poverty.

Bolsonaro's environmental policies have been widely condemned but he has rejected the criticism, saying Brazil remains an example for conservation.

Paris, Apr 17: Even as virologists zero in on the virus that causes COVID-19, a very basic question remains unanswered: do those who recover from the disease have immunity?

There is no clear answer to this question, experts say, even if many have assumed that contracting the potentially deadly disease confers immunity, at least for a while.

"Being immunised means that you have developed an immune response against a virus such that you can repulse it," explained Eric Vivier, a professor of immunology in the public hospital system in Marseilles.

"Our immune systems remember, which normally prevents you from being infected by the same virus later on."

For some viral diseases such a measles, overcoming the sickness confers immunity for life.

But for RNA-based viruses such as Sars-Cov-2 -- the scientific name for the bug that causes the COVID-19 disease -- it takes about three weeks to build up a sufficient quantity of antibodies, and even then they may provide protection for only a few months, Vivier told AFP.

At least that is the theory. In reality, the new coronavirus has thrown up one surprise after another, to the point where virologists and epidemiologists are sure of very little.

"We do not have the answers to that -- it's an unknown," Michael Ryan, executive director of the World Health Organization's Emergencies Programme said in a press conference this week when asked how long a recovered COVID-19 patient would have immunity.

"We would expect that to be a reasonable period of protection, but it is very difficult to say with a new virus -- we can only extrapolate from other coronaviruses, and even that data is quite limited."

For SARS, which killed about 800 people across the world in 2002 and 2003, recovered patients remained protected "for about three years, on average," Francois Balloux director of the Genetics Institute at University College London, said.

"One can certainly get reinfected, but after how much time? We'll only know retroactively."

A recent study from China that has not gone through peer review reported on rhesus monkeys that recovered from Sars-Cov-2 and did not get reinfected when exposed once again to the virus.

"But that doesn't really reveal anything," said Pasteur Institute researcher Frederic Tangy, noting that the experiment unfolded over only a month.

Indeed,several cases from South Korea -- one of the first countries hit by the new coronavirus -- found that patients who recovered from COVID-19 later tested positive for the virus.

But there are several ways to explain that outcome, scientists cautioned.

While it is not impossible that these individuals became infected a second time, there is little evidence this is what happened.

More likely, said Balloux, is that the virus never completely disappeared in the first place and remains -- dormant and asymptomatic -- as a "chronic infection", like herpes.

As tests for live virus and antibodies have not yet been perfected, it is also possible that these patients at some point tested "false negative" when in fact they had not rid themselves of the pathogen.

"That suggests that people remain infected for a long time -- several weeks," Balloux added. "That is not ideal."

Another pre-publication study that looked at 175 recovered patients in Shanghai showed different concentrations of protective antibodies 10 to 15 days after the onset of symptoms.

"But whether that antibody response actually means immunity is a separate question," commented Maria Van Kerhove, Technical Lead of the WHO Emergencies Programme.

"That's something we really need to better understand -- what does that antibody response look like in terms of immunity."

Indeed, a host of questions remain.

"We are at the stage of asking whether someone who has overcome COVID-19 is really that protected," said Jean-Francois Delfraissy, president of France's official science advisory board.

For Tangy, an even grimmer reality cannot be excluded.

"It is possible that the antibodies that someone develops against the virus could actually increase the risk of the disease becoming worse," he said, noting that the most serious symptoms come later, after the patient had formed antibodies.

For the moment, it is also unclear whose antibodies are more potent in beating back the disease: someone who nearly died, or someone with only light symptoms or even no symptoms at all. And does age make a difference?

Faced with all these uncertainties, some experts have doubts about the wisdom of persuing a "herd immunity" strategy such that the virus -- unable to find new victims -- peters out by itself when a majority of the population is immune.

"The only real solution for now is a vaccine," Archie Clements, a professor at Curtin University in Perth Australia, told AFP.

At the same time, laboratories are developing a slew of antibody tests to see what proportion of the population in different countries and regions have been contaminated.

Such an approach has been favoured in Britain and Finland, while in Germany some experts have floated the idea of an "immunity passport" that would allow people to go back to work.

"It's too premature at this point," said Saad Omer, a professor of infectious diseases at the Yale School of Medicine.

"We should be able to get clearer data very quickly -- in a couple of months -- when there will be reliable antibody tests with sensitivity and specificity."

One concern is "false positives" caused by the tests detecting antibodies unrelated to COVID-19.

The idea of immunity passports or certificates also raises ethical questions, researchers say.

"People who absolutely need to work -- to feed their families, for example -- could try to get infected," Balloux.
