Californian start-up Aptera has debuted what it claims to be the first production-ready solar electric vehicle that doesn't need to be plugged in for day-to-day driving, developed with help from Pininfarina.Aptera debuted the vehicle which features solar panels on its hood, dash, roof and hatch at the Consumer Electronics Show (CES) in Las Vegas this week.The company claims the car could significantly reduce reliance on the grid for charging because, under the right conditions, it can drive up to 40 miles (64 kilometres) per day powered entirely by sunlight, with no need to be plugged in between uses.Aptera's electric vehicle has solar panels built into the roof and hatchThis should be enough to cover the daily needs of the average American, who drivesabout 37 miles (60km) per day.For longer drives or cloudy days, the Aptera vehicle includes a battery that the company says gives up to 400 miles (643km) of range from under an hour of charging.The car's range is enabled by its unusual design, intended to be ultra-aerodynamic. The three-wheeled, two-seater vehicle has a teardrop-shaped body, which was finessed in partnership with Italian automotive design studio Pininfarina.The solar panels enable the car to drive everyday trips without grid chargingAptera used the company's wind tunnel in Turin, Italy, to validate the design, working closely with the Pininfarina team to hone the shape so it would create the lowest possible drag coefficient a figure used to quantify the resistance an object experiences when moving through air.Aptera says its vehicle has the lowest drag coefficient of any production passenger vehicle "closer to an airplane's aerodynamics than to typical cars".The carmaker has not shared what exactly that figure is, although a specification document from 2023 shows the company was aiming for 0.13, whereas most modern vehicles come in at around 0.25 to 0.3.The car has two seats and three wheelsAnother key to the car's range is its lightweight body, primarily made from a type of carbon fibre called carbon fibre sheet moulding compound (CF-SMC).The material is mouldable into complex shapes, allowing the company to construct the light yet robust car from only six key body components.The CF-SMC is made by the CPC Group in Modena, Italy, which also serves luxury and sports car companies such as Ferrari, Lamborghini and McLaren.Read: Lotus unveils Theory 1 concept car as "design manifesto" for the futureAptera Motors said the debut of the "production-ready" vehicle marked a pivotal moment for the future of sustainable transportation."This vehicle embodies years of innovation and relentless pursuit of energy-efficient mobility," said co-CEO Chris Anthony. "CES is the perfect stage to share our vision and invite the world to join us in creating a cleaner, solar-powered future."This is the second go-round at making a solar electric vehicle for Aptera, which was founded in 2006 before running out of money and liquidating in 2011.The car is on show at the Consumer Electronics Show (CES)The original founders Anthony and Steven Fambro relaunched the company in 2019.As of October 2024, Aptera reported it had 50,000 pre-order reservation holders.The world's largest consumer electronics fair, CES is on from January 7 to 10. Alongside car companies revealing concepts, prototypes and production models, this year's event showcased a hormone thermometer, a three-in-one projector and a tiny cat robot that blows on soup to cool it.CES 2025takes place at various locations in Las Vegas from 7 to 10 January 2025.

This article first appeared in The Checkup,MIT Technology Reviewsweekly biotech newsletter. To receive it in your inbox every Thursday, and read articles like this first,sign up here.This week marks a strange anniversaryits five years since most of us first heard about a virus causing a mysterious pneumonia. A virus that we later learned could cause a disease called covid-19. A virus that swept the globe and has since been reported to have been responsible for over 7 million deathsand counting.I first covered the virus in an article published on January 7, 2020, which had the headline Doctors scramble to identify mysterious illness emerging in China. For that article, and many others that followed it, I spoke to people who were experts on viruses, infectious disease, and epidemiology. Frequently, their answers to my questions about the virus, how it might spread, and the risks of a pandemic were the same: We dont know.We are facing the same uncertainty now with H5N1, the virus commonly known as bird flu. This virus has been decimating bird populations for years, and now a variant is rapidly spreading among dairy cattle in the US. We know it can cause severe disease in animals, and we know it can pass from animals to people who are in close contact with them. As of this Monday this week, we also know that it can cause severe disease in peoplea 65-year-old man in Louisiana became the first person in the US to die from an H5N1 infection.Scientists are increasingly concerned about a potential bird flu pandemic. The question is, given all the enduring uncertainty around the virus, what should we be doing now to prepare for the possibility? Can stockpiled vaccines save us? And, importantly, have we learned any lessons from a covid pandemic that still hasnt entirely fizzled out?Part of the challenge here is that it is impossible to predict how H5N1 will evolve.A variant of the virus caused disease in people in 1997, when there was a small but deadly outbreak in Hong Kong. Eighteen people had confirmed diagnoses, and six of them died. Since then, there have been sporadic cases around the worldbut no large outbreaks.As far as H5N1 is concerned, weve been relatively lucky, says Ali Khan, dean of the college of public health at the University of Nebraska. Influenza presents the greatest infectious-disease pandemic threat to humans, period, says Khan. The 1918 flu pandemic was caused by a type of influenza virus called H1N1 that appears to have jumped from birds to people. It is thought to have infected a third of the worlds population, and to have been responsible for around 50 million deaths.Another H1N1 virus was responsible for the 2009 swine flu pandemic. That virus hit younger people hardest, as they were less likely to have been exposed to similar variants and thus had much less immunity. It was responsible for somewhere between 151,700 and 575,400 deaths that year.To cause a pandemic, the H5N1 variants currently circulating in birds and dairy cattle in the US would need to undergo genetic changes that allow them to spread more easily from animals to people, spread more easily between people, and become more deadly in people. Unfortunately, we know from experience that viruses need only a few such changes to become more easily transmissible.And with each and every infection, the risk that a virus will acquire these dangerous genetic changes increases. Once a virus infects a host, it can evolve and swap chunks of genetic code with any other viruses that might also be infecting that host, whether its a bird, a pig, a cow, or a person. Its a big gambling game, says Marion Koopmans, a virologist at the Erasmus University Medical Center in Rotterdam, the Netherlands. And the gambling is going on at too large a scale for comfort.There are ways to improve our odds. For the best chance at preventing another pandemic, we need to get a handle on, and limit, the spread of the virus. Here, the US could have done a better job at limiting the spread in dairy cows, says Khan. It should have been found a lot earlier, he says. There should have been more aggressive measures to prevent transmission, to recognize what disease looks like within our communities, and to protect workers.States could also have done better at testing farm workers for infection, says Koopmans. Im surprised that I havent heard of an effort to eradicate it from cattle, she adds. A country like the US should be able to do that.The good news is that there are already systems in place for tracking the general spread of flu in people. The World Health Organizations Global Influenza Surveillance and Response System collects and analyzes samples of viruses collected from countries around the world. It allows the organization to make recommendations about seasonal flu vaccines and also helps scientists track the spread of various flu variants. Thats something we didnt have for the covid-19 virus when it first took off.We are also better placed to make vaccines. Some countries, including the US, are already stockpiling vaccines that should be at least somewhat effective against H5N1 (although it is difficult to predict exactly how effective they will be against some future variant). The US Administration for Strategic Preparedness and Response plans to have up to 10 million doses of prefilled syringes and multidose vials prepared by the end of March, according to an email from a representative.The US Department of Health and Human Services has also said it will provide the pharmaceutical company Moderna with $176 million to create mRNA vaccines for pandemic influenzausing the same quick-turnaround vaccine production technology used in the companys covid-19 vaccines.Some question whether these vaccines should have already been offered to dairy farm workers in affected parts of the US. Many of these individuals have been exposed to the virus, a good chunk of them appear to have been infected with it, and some of them have become ill. If the decision had been up to Khan, he says, they would have been offered the H5N1 vaccine by now. And we should ensure they are offered seasonal flu vaccines in order to limit the risk that the two flu viruses will mingle inside one person, he adds.Others worry that 10 million vaccine doses arent enough for a country with a population of around 341 million. But health agencies walk a razor-thin line between having too much vaccine for something and not having enough, says Khan. If an outbreak never transpires, 340 million doses of vaccine will feel like an enormous waste of resources.We cant predict how well these viruses will work, either. Flu viruses mutate all the time, and even seasonal flu vaccines are notoriously unpredictable in their efficacy. I think weve become a little bit spoiled with the covid vaccines, says Koopmans. We were really, really lucky [to develop] vaccines with high efficacy.One vaccine lesson we should have learned from the covid-19 pandemic is the importance of equitable access to vaccines around the world. Unfortunately, its unlikely that we have. It is doubtful that low-income countries will have early access to [a pandemic influenza] vaccine unless the world takes action, Nicole Lurie of the Coalition for Epidemic Preparedness Innovations (CEPI) said in a recent interview for Gavi, a public-private alliance for vaccine equity.And another is the impact of vaccine hesitancy. Making vaccines might not be a problembut convincing people to take them might be, says Khan. We have an incoming administration that has lots of vaccine hesitancy, he points out. So while we may end up having vaccines available, its not very clear to me if we have the political and social will to actually implement good public health measures.This is another outcome that is impossible to predict, and I wont attempt to do so. But I am hoping that the relevant administrations will step up our defenses. And that this will be enough to prevent another devastating pandemic.Now read the rest of The CheckupRead more from MIT Technology Reviews archiveBird flu has been circulating in US dairy cows for months.

Listening to someone is not the same as agreeing with themPublished inThe Medium BlogSent as aNewsletter3 min readJust now-- Be safe this weekendIssue #243: literary rejections, good storytelling, and unconscious envyIm guessing some of you saw this, but: Yesterday, at former U.S. President Jimmy Carters funeral, Barack Obama was seated next to Donald Trump. They were in the second row, behind Kamala Harris and surrounded by all 5 living U.S. presidents.The history of animosity between these two goes back three election cycles, and its not pretty. In 2012, Trump tweeted that Obamas birth certificate was fraudulent (its not). While campaigning in 2016, he referred to Obama as ignorant, a disaster, and the founder of ISIS. And recently, Obama finished a campaign tour for Kamala Harris presidential candidacy in which he argued that Trumps approach to politics is divisive and would be dangerous for the U.S. Its not an exaggeration to say their political careers have been partially built on tearing each other down, or at least positioning themselves as the better alternative.Yet, they seemed to get along fine yesterday. Maybe even more than fine. Trump told a joke (?) and Obama laughed. Obama whispered something back to him later in the ceremony.Image credit: CSPANThis made news. It surprised people. Some read the moment as hypocritical or sinister in some way, evidence that Americas leaders are unprincipled. Thats one take. A more positive perspective is that basic humanity transcends politics, which is actually pretty refreshing (to me, at least) right now, when everything from raging wildfires to private companies content moderation policies are immediately politicized to score Internet Points. Yes, its normal to be cordial toward your seatmate at a funeral. This shouldnt be controversial? Funerals are reminders that, no matter who youre dunking on today, no matter what power or money youve won or lost, our time here is short and most of this will be forgotten.(Small caveat to note the event was not grudge-less! Karen Pence and George W. Bush apparently both refused to shake Donald Trumps hand, though Bush did give Obama an amusing belly tap at one point.)Remember theres a time and place to disagree, wrote Saul Austerlitz on Medium a few years ago, in a story about how to talk to someone whos opinions you cant stand. Listening, even laughing with someone, is not the same as agreeing with them. Maybe thats a useful distinction to take with us into the weekend.

On This Day in HistoryAmericas First Viral Post Was Published on This Day in 1776, When Thomas Paines Common Sense Sparked a RevolutionThe Englishmans pamphlet helped spur the 13 colonies to declare independence from Britain Portrait of Thomas Paine by Laurent Dabos National Portrait Gallery, Smithsonian InstitutionIt was Philadelphia in the winter of 1776. In the few years prior, the colonies faraway owner, Britain, had imposed taxation without representation and the so-called Intolerable Acts; colonists had convened at two Continental Congresses; and British and American troops had battled for the first time at Bunker Hill.Revolutionary sentiment had been brewing throughout the American colonies for some time and was near boiling in the Northeast. Still, many colonists had not seriously considered separating from the mother countryuntil a history-making pamphlet was published in the City of Brotherly Love on January 10, 1776.Thomas Paines Common Sense, addressed to the inhabitants of America, was a 47-page dynamo presenting the recently immigrated Englishmans clear case for Americas independence from Britain. Paines words flew off the shelves, selling tens of thousands of copies within weeks.The text has been called Americas first viral communications event: Its content gripped and inspired Americans, who loudly read it aloud on the street and in bars, spreading Paines message.In short, Paines argument was that given Britains tyrannical rule, the only way forward for the American colonies was to become an independent country. He tore down the idea of monarchy, questioning the legitimacy of kings like George III, who, like all other British kings, was seen as divinely ordained to rule.The divine right of kings is a lie; monarchy runs against Gods plans, Paine wrote. For all men being originally equals, no one by birth could have a right to set up his own family in perpetual preference to all others for ever.Paine encouraged colonists to unite against their colonial overlord and take their independence, then decide as a people who should govern them, as is their natural right. He accused those opposed to American independence of opening a door to eternal tyranny, reminding readers of the suffering Britain had inflicted upon them in the colonies and asserting that most of the colonies economic problems could be solved by separating from Britain.Just half a year after Common Sense hit the presses, the Declaration of Independence was signed in Philadelphiaa move certainly influenced by Paines writing, which inspired its chief author, Thomas Jefferson. Later that same year, when the colonies were on their backs, Paine wrote lin American Crisis the famous words: These are the times that try mens souls.Tyranny, like Hell, is not easily conquered; yet we have this consolation with us, that the harder the conflict, the more glorious the triumph, he added. By the end of the American Revolution, Paine was regarded as a national hero.In the following decades, however, he became an outcast: The public didnt approve of Paines belief that organized religions promoted false representations of God, controlled the faithful and hoarded money. When Paine died in June 1809, only six people attended his burial in New Rochelle, New York.When Paine first published Common Sense, he did so anonymously, fearing hed be punished for treason if identified. He donated the royalties to the Continental Army. In time, Paine allowed for free reproduction of the pamphlet, ensuring its message was spread even further. By the end of the American Revolution, the pamphlet which was at first attributed simply to an Englishman had sold up to half a million copies.Or had it? Despite being hailed as the most viral work of its time, the true extent of Common Senses publication is contested. Paine himself claimed that over 100,000 copies of the pamphlet were in circulation, and a later biographer inflated the claim to half a million. That led a longstanding myth that a full 20 percent of recorded colonists probably owned a copy of Common Sense in 1776. But historian Ray Raphael notes these figures are implausible and writes that, given scant record-keeping at the time, we simply do not know how many copies were sold.Viral or no, Paines message resounded with colonists hungry for independence. But the exact extent of his publishing phenomenon has yet to be confirmed.Get the latest stories in your inbox every weekday.
