But among the search for Higgs bosons and the endless unspooling of string theories, there remained a particularly glaring mystery: Why does a teakettle whistle? “Oh that,” they said, standing at their stoves in between bouts of programming supercomputers. “Vibrations. Or something.” Now, we are happy to report, human intellect has at last triumphed over the dark shadow of ignorance and solved the conundrum lurking within one of our lowest-tech kitchen appliances…. And having solved another mystery of our vast but perhaps ultimately knowable universe, they smile and sip their tea.Discovery in the knee: One would think after centuries of dissections and surgeries that the human knee is pretty well understood. Not so; a “new” ligament has been discovered, reported the BBC News, named the anterolateral ligament. It looks pretty obvious from the photo in Medical Xpress. It’s important, too: it helps protect the knee when we twist or change direction. Without it, the knee can suddenly give way. A surgeon outside the study group remarked, “If you look back through history there has been a veiled understanding that something is going on on that side of the knee but this work finally gives us a better understanding.”Manhattan’s Grand Canyon: Just 100 miles off Manhattan’s shores, a canyon rivaling the Grand Canyon plunges off the continental shelf into the deep sea. Live Science says that Hudson Canyon is “a city in its own right, brimming with an extraordinary universe of life.” So close to the busiest city on earth, it’s a gigantic feature biologists are only beginning to inventory, inhabited by animals small and great – from plankton to sperm whales, corals, squid, sea anemones, swordfish and much more, some of which are shown in an embedded video clip. Hudson is just one of 15 such large submarine canyons along the east coast south of Cape Cod that the article says are remnants of ancient rivers that flowed off the continental shelf when sea level was lower. Beyond the canyon is a series of prominent seamounts – dormant volcanoes rising thousands of feet from the seafloor.Those large canyons appear to be Flood remnants. It’s hard to imagine ordinary rivers carving so many canyons that huge so close to one another. Only if massive, unprecedented waters were draining off the continents would these remnant geological features be expected.Once science can figure out the teakettle, maybe it can move on to more grandiose ambitions like explaining why toast tends to land buttered side down. Those problems at least are tractable. Evolution is so full of variables, unknowns and degrees of freedom, its error bars surpass the axes. That’s why any story fits between the error bars. Let’s tell the Darwin Party to stop wasting our time with speculations about the unobservable past, and help the guy with the bum knee get through physical therapy. He needs compassionate evidence-based knowledge of knee structure and function, not storytelling about how vacant ecospace led to the Cambrian explosion.
The Maharashtra government has made arrangements to send the body of a Kerala fisherman, who died off the Maharashtra coast, Chief Minister Devendra Fadnavis said on Tuesday. Mr. Fadnavis’ response came after Congress MP and former Union Minister Shashi Tharoor reached out to him on Twitter.“Dear Mr. Tharoor, Ratnagiri Collector already in touch with Thiruvananthapuram Collector since Monday afternoon. All necessary arrangements being done to transport body of Kerala fisherman,” Mr. Fadnavis tweeted.Earlier, Mr. Tharoor had urged the body of fisherman Rajumon floating near the Maharashtra coast be send back urgently. A total of nine persons were not the boat when tragedy struck in which one person lost his life. Reports said Rajumon, 41, died after falling sick.“Dear @Dev_Fadnavis, Rajumon (41), a Kerala fisherman, died at sea. His boat is now near the Maharashtra coast. Need help to bring the body to shore and to transport by air to Thiruvananthapuram. Please facilitate” Mr. Tharoor had tweeted.The Congress MP later tweeted an update and thanked the state government for the efforts when the body reached Ratnagiri’s local hospital. “It will be transported to Thiruvananthapuram after autopsy, I thank the Maharashtra government for co-operation.”

Today, Audi is announcing another four cities in the US, effectively doubling the number of traffic lights that it can monitor here. The TLI system relies on vehicle-to-infrastructure (V2I) communications to wirelessly send the timing of a municipality’s traffic lights directly to the car using its integrated LTE connectivity. The car then uses that information to say, if you’re waiting at a red light, how much longer it will stay red. Or, if you’re approaching a “stale” green light that’s about to change, the car can tell you that you’re not going to make it, meaning you might as well just coast to a stop and save both some gas and your brakes. The timers and instructions appear on both Audi’s Virtual Cockpit system and on the heads-up display, if equipped, letting drivers know whether they have time to queue up another playlist before the light turns green, or if they should stop rocking and get ready to roll. The four new cities going live today are Denver, Colorado; White Plains, New York; Gainesville, Florida and Orlando, Florida. That’s a total of 13 cities in the US where the service works, or some 4,700 intersections. If you find yourself commuting through one of those 13, then lucky you, but you will need to pay for the privilege of receiving that sweet metadata. TLI is part of Audi’s Connect Prime services package, which costs $199 for six months or $499 for 18 months. You do, at least, get the first six months free. Share your voice Tags Auto Tech Audi
Comment Preview • iPhone XS is the new $1,000 iPhone X The Cheapskate Some of the Democratic candidates got more attention on Twitter than others. Getty Images Even though the 2020 election is more than a year away, debate season is upon us. As 10 Democratic presidential candidates took the stage for the first time Wednesday night, folks on Twitter were primed for meme-able moments and general buzz. Data from Twitter Wednesday shows that the top-tweeted moments of the night were Cory Booker speaking in Spanish (he wasn’t the first or only candidate to do so); Elizabeth Warren saying she had a plan to “deal with” House Speaker Mitch McConnell; and the technical difficulties around some mics left on.The most tweeted-about candidates on the stage for the Democratic debate were:Elizabeth WarrenCory BookerJulián CastroBeto O’RourkeAmy KlobucharTulsi GabbardWhen it came to the most tweeted-about US politicians, though, President Donald Trump took the top spot, followed by Warren, Booker, Castro, President Barack Obama and Bernie Sanders (who will participate in Thursday’s debate). Though not technically a Labor Day sale, it’s happening during Labor Day sale season — and it’s too good not to share.

Wait — no, I’m not. As much as I respect the original intent of the holiday (which became official back in 1894), to most of us, it’s just a bonus day off — one that’s blissfully tacked onto a weekend. So, yeah, stores; go ahead, run your sales. I’m listening. Perhaps unsurprisingly, Labor Day doesn’t bring out bargains to compete with the likes of Black Friday (which will be here before you know it), but there are definitely some sales worth your time.For example:We’ve rounded up the best Labor Day mattress deals.We’ve also gathered the best Labor Day laptop deals at Best Buy.The 2019 Vizio P Series Quantum is back under $999.Be sure to check out Amazon’s roughly three dozen Labor Day deals on TVs and audio.

Read Lenovo Smart Clock review The problem with most entry-level laptops: They come with mechanical hard drives. That makes for a mighty slow Windows experience. This Lenovo model features a 128GB solid-state drive, so it should be pretty quick to boot and load software, even with its basic processor. Plus, it has a DVD-burner!

Conspiracy theorists all across the world have long been alleging that aliens are secretly living on the lunar surface. These alien enthusiasts strongly believe that NASA is well aware of extraterrestrial existence on the lunar surface, and it is one of the primary reasons that refrained the agency to visit the moon after the Apollo mission era.Adding heat to these outlandish alien claims, a transcript between astronauts who were part of the Apollo 15 mission reveals that they found neatly organized tracks on the lunar surface, Express.co.uk reports.These tracks on the lunar surface were leading to Mount Hadley, a mountain range located in the Northern Hemisphere on the moon. Please find below the transcripts between Apollo 15 astronauts and the ground crew, as reported by Express. Express.co.ukAs this conversation between the astronauts and the ground crew became viral, conspiracy theorists strongly started arguing that these tracks are concrete proof of alien existence on the lunar surface. These conspiracy theorists strongly argued that several anomalies in NASA images from the moon, and the recent UFO sightings near earth’s natural satellites indicate the presence of artificial intelligence.A few months back, China had landed its Chang’e-4 probe on the dark side of the moon. Before the mission, many conspiracy theorists predicted that the Chinese mission will encounter extraterrestrial aliens on moon’s far side that is not visible from the earth due to tidal locking. However, the mission went ahead as planned, and until now, Chang’e-4 has not detected any traces of extraterrestrial presence there.On July 15, India had planned to launch their ‘Chandrayaan-2’ space probe to the dark side of the moon. However, due to unknown technical glitches, the launch was postponed. The Indian Space Research Organization (ISRO) is expected to announce a new launch date soon.
Kashmiri women shout slogans during a protest after the scrapping of the special constitutional status for Kashmir by the Indian government, in Srinagar, on 11 August 2019. Photo: ReutersIndian authorities reimposed some restrictions in parts of Kashmir on Sunday ahead of the Muslim festival Eid, amid fears that large gatherings could trigger renewed protests against Delhi’s withdrawal of special rights for the region.Indian prime minister Narendra Modi’s government locked down the Muslim-majority region last Sunday, cutting off communications, detaining more than 300 political leaders and activists, and putting a ‘virtual curfew’ into force with numerous police and army roadblocks stopping movement by many residents.Seeking to tighten its grip on the region also claimed by neighbouring Pakistan, India scrapped Jammu and Kashmir’s right to frame its own laws and allowed non-residents to buy property there.On Friday, restrictions on movement in some parts of the Himalayan region’s main city of Srinagar were relaxed, with people pouring out on to the streets to stock up on provisions.But protests erupted after Friday prayers, with pro-independence youth demonstrating before being repelled by tear gas and pellets, according to police sources, witnesses and footage shown by international broadcasters.On Sunday, a Reuters reporter saw a police van driving around one part of Srinagar announcing that restrictions had been imposed again and asking people to stay indoors.Police checkpoints were also placed on some roads leading to the old quarter of the city, a traditional hotbed of protests, and some streets in central Srinagar.Officials were debating how to handle Monday’s Eid-al-Azha festival, one of the two most important festivals of the Islamic calendar, which typically sees several thousands throng major mosques in Srinagar.Indian officials will hold a video-conference with senior police and administration officials from all 10 districts in the disputed Kashmir valley on Sunday evening to decide on restrictions, two senior state government officials told Reuters.”We will make an assessment of the situation today,” one official said, requesting anonymity because he is not authorised to speak to the media. “I do not think we will allow large gatherings.”Kashmiri men shout slogans during a protest after the scrapping of the special constitutional status for Kashmir by the Indian government, in Srinagar, on 11 August 2019. Photo: ReutersIndia’s home ministry did not immediately respond to a request for comment on the latest restrictions in Kashmir.Leaders in Kashmir had warned of a backlash against the stripping of autonomy in a territory where militants have been fighting Indian rule for nearly 30 years, leading to the deaths of more than 50,000 people.Reuters reported at least 10,000 people were involved in Friday’s protest in Srinagar’s Soura area, based on an estimate provided by a police source and backed up by two eyewitnesses. Another official source on Saturday gave Reuters the same estimate.Dilbag Singh, the Jammu and Kashmir director general of police, told Reuters on Sunday that between 1,000 and 1,500 people were returning from praying at mosques on Friday when “some miscreants” started pelting stones at security officials.”It was a reaction to stone pelting by these miscreants that one or two rounds of pump action gun was fired,” Singh said, adding that four to five men suffered injuries.Authorities had detained around 300 local leaders in total and some of them had been taken out of Kashmir, he said.Pakistan’s WrathPakistan has downgraded diplomatic ties with India and suspended trade in anger at Delhi’s latest move.Pakistani prime minister Imran Khan on Sunday compared India’s ruling Hindu nationalist party’s policies to dictator Adolf Hitler’s “Nazi Aryan Supremacy.” He warned Modi’s actions would go beyond Kashmir and eventually target Indian Muslims and neighbouring Pakistan.”Attempt is to change demography of Kashmir through ethnic cleansing. Question is: Will the world watch & appease as they did Hitler at Munich?” Khan tweeted.Ram MAzhav, a senior leader in India’s ruling Hindu nationalist Bharatiya Janata Party (BJP), hit back.”Threat to democratic world is from Pak-sponsored Jehadi terror, not from India,” MAzhav tweeted.Pakistan said on Saturday that it had gained China’s support to take a motion to the United Nations Security Council condemning the Indian decision to change the status of Jammu and Kashmir.Islamabad has not received much support from other major nations, however, suggesting its odds of success at the UN were slim.India’s BJP has long campaigned for abrogating Kashmir’s special privileges in the constitution, which it sees as an appeasement to Muslims and a hindrance to its own development.The BJP and even some top opposition leaders have welcomed the decision to absorb Kashmir fully into India, and it has brought Modi support across the country.Blocked off from the world and largely unable to work or socialize, many Kashmiris were sombre ahead of Monday’s festival. Some said they would not partake in the ritual sacrificing of sheep.”What kind of Eid is this?” said one elderly man walking down a street in downtown Srinagar’s Jamia Masjid area. “We cannot reach our loves ones, we cannot visit our relatives’ homes, then what are we celebrating?” he said, declining to be named.
