TripAdvisor has defended itself against accusations of misleading travelers by failing to stop some of its highest ranked hotels winning their status with fake reviews.UK consumer group Which? Travel analyzed a total of almost 250,000 reviews for the 10 top-ranked hotels in 10 global tourist destinations, from Las Vegas to Cape Town. It found that one in seven of the hotels had "blatant hallmarks" of fake reviews, with others raising "serious concerns."But TripAdvisor called the analysis "flawed" and said its more sophisticated detection tools were able to weed out fraudulent feedback.Which? Travel said that when it reported 15 of the worst cases to TripAdvisor, the reviews giant -- now one of the world's biggest travel websites -- admitted that all but one of the hotels in question had been caught using fake reviews in the past year.Six had previously been penalized, and two had received a "red badge warning" -- where TripAdvisor warns users that the hotel is suspected of using fake reviews, and has "repeatedly failed to remedy its behavior and refuses to cooperate with TripAdvisor's investigators."Yet, Which? Travel said it found that the review patterns had continued unabated despite the measures, and the red badges had been removed.The group has accused TripAdvisor of a "lack of serious ongoing action to address repeated abuse of the system."It says that five-star reviews left by new users who have written no other reviews should be a red flag. Its analysis compared the proportion of first-time five-star reviews with that of first-time three-star reviews, which are less likely to be faked.In total, it studied 247,277 reviews."TripAdvisor's failure to stop fake reviews and take strong action against hotels that abuse the system risks misleading millions of travelers and potentially ruining their holidays," said Which? Travel's Naomi Leach.TripAdvisor has removed hundreds of reviews in light of the investigation, Which? Travel claimed."Striking" evidence of fake reviewsHotels in the Middle East had "striking" amounts of fake positive reviews, according to the research. TripAdvisor docked 730 five-star reviews of the "best" hotel in Jordan following the analysis -- but the hotel has not been given a red badge. It remains in the top 10 in the country.At the top-ranking hotel in Cairo, 79% of five-star reviews came from one-time contributors. Just 14% of three-star reviews came from similar accounts.The hotel has lost its status as a result of the reviews' deletion.Las Vegas was another hotspot for fake reviews. At two of the top-rated hotels, almost half the five-star reviews came from one-time contributors. For a competitor which did not arouse suspicion, the figure was just 3%.Some of the top-ranked hotels in London, Paris, Barcelona and Cape Town "gave reason for suspicion," the research showed, but failed to demonstrate the same patterns across the board.Repeat offendersTripAdvisor called the analysis "based on a flawed understanding of fake review patterns," adding that "it is simply far too simplistic to assume all first-time reviewers are suspicious."It said that Which? Travel did not have access to IP [internet protocol] information or location data, both of which TripAdvisor uses to detect fake reviews."We analyze hundreds of data points about each review -- most of which only we have access to -- and we combine that data with a wealth of knowledge and understanding of review patterns that our team of experts has gained from tracking hundreds of millions of reviews over a near 20-year period," said the company."This includes an ability to track and analyze first-time reviews in far more detail and with far more rigor than Which's team was able to do."Online reviews influence an annual estimated ￡23 billion ( billion) of booking transactions in the UK alone, according to the UK government."Sites like TripAdvisor must do more to ensure the information on their platforms is reliable," said Naomi Leach."If they continue to fall short, they should be compelled to make changes so holidaymakers are no longer at risk of being duped by a flood of fake reviews." 4152

Tropical Storms Olga and Pablo formed simultaneously on Friday, with Tropical Storm Olga expected to come ashore tonight along the Louisiana coast. Although Tropical Storm Olga will be making landfall this evening, no tropical storm warnings or watches were issued by the National Hurricane Center. The National Hurricane Center said that Olga will merge with a cold front tonight and will become extratropical. Flood and tornado watches were issued for segments of the Gulf Coast. Top winds for Olga were 40 MPH as of 4 p.m. CT. The top winds for Pablo were 45 MPH as of 5 p.m. ET. Pablo is not execpted to be a threat to land. 640

The slow-churning remnants of Tropical Storm Imelda that flooded parts of Texas left at least two people dead and rescue crews with boats scrambling to reach stranded drivers and families trapped in their homes during a relentless downpour that drew comparisons to Hurricane Harvey two years ago.By Thursday night, floodwaters had started receding in most of the Houston area, said the city's mayor, Sylvester Turner. Law enforcement officers planned to work well into the night to clear freeways of vehicles stalled and abandoned because of flooding, Houston Police Chief Art Acevedo said.Officials in Harris County, which includes Houston, said there had been a combination of at least 1,700 high-water rescues and evacuations to get people to shelter as the longevity and intensity of the rain quickly came to surprise even those who had been bracing for floods. The storm also flooded parts of southwestern Louisiana.More than 900 flights were canceled or delayed in Houston. Further along the Texas Gulf Coast, authorities at one point warned that a levee could break near Beaumont in Jefferson County. During Harvey, Beaumont's only pump station was swamped by floodwaters, leaving residents without water service for more than a week.Imelda's remnants Thursday led to the deaths of two men. A 19-year-old man drowned and was electrocuted while trying to move his horse to safety, according to a message from his family shared by the Jefferson County Sheriff's Office. Crystal Holmes, a spokeswoman for the department, said the death occurred during a lightning storm.A man in his 40s or 50s drowned when he tried to drive a van through 8-foot-deep floodwaters near Bush Intercontinental Airport in Houston during the Thursday afternoon rush hour, Harris County Sheriff Ed Gonzalez said. 1805

The remains of an ancient ape found in a Bavarian clay pit suggest that humans’ ancestors began standing upright millions of years earlier than previously thought, scientists said Wednesday.An international team of researchers says the fossilized partial skeleton of a male ape that lived almost 12 million years ago in the humid forests of what is now southern Germany bears a striking resemblance to modern human bones. In a paper published by the journal Nature, they concluded that the previously unknown species — named Danuvius guggenmosi — could walk on two legs but also climb like an ape.The findings “raise fundamental questions about our previous understanding of the evolution of the great apes and humans,” said Madelaine Boehme of the University of Tuebingen, Germany, who led the research.The question of when apes evolved bipedal motion has fascinated scientists since Charles Darwin first argued that they were the ancestors of humans. Previous fossil records of apes with an upright gait — found in Crete and Kenya — dated only as far back as 6 million years ago.Boehme, along with researchers from Bulgaria, Germany, Canada and the United States, examined more than 15,000 bones recovered from a trove of archaeological remains known as the Hammerschmiede, or Hammer Smithy, about 70 kilometers (44 miles) west of the Germany city of Munich.Among the remains they were able to piece together were primate fossils belonging to four individuals that lived 11.62 million years ago. The most complete, an adult male, likely stood about 1 meter (3 feet, 4 inches) tall, weighed 31 kilograms (68 pounds) and looked similar to modern-day bonobos, a species of chimpanzee.“It was astonishing for us to realize how similar certain bones are to humans, as opposed to great apes,” Boehme said.Thanks to several well-preserved vertebra, limb, finger and toe bones, the scientists were able to reconstruct how Danuvius moved, concluding that while it would have been able to hang from branches by his arms, it could also straighten its legs to walk upright.“This changes our view of early human evolution, which is that it all happened in Africa,” Boehme told The Associated Press in an interview.Like humans, Danuvius had an S-shaped spine to hold its body upright while standing. Unlike humans, though, it had a powerful, opposable big toe that would have allowed it to grab branches with its foot and safely walk through the treetops.Fred Spoor, a paleontologist at the Natural History Museum in London, called the fossil finds “fantastic” but said they would likely be the subject of much debate, not least because they could challenge many existing ideas about evolution.“I can see that there will be a lot of agonizing and re-analysis of what these fossils mean,” said Spoor, who wasn’t involved in the study. 2833

The Texas Department of State Health Services and Fort Bend County Health and Human Services are reporting the first positive test result for coronavirus in Texas outside of the passengers returned from Wuhan City or the Diamond Princess cruise ship. The DSHS says the patient is a resident of Fort Bend County and recently returned from travel abroad. The patient is currently isolated in the hospital. The test was performed at the public health lab in Houston and will be confirmed by testing at the Centers for Disease Control and Prevention. DSHS is supporting Fort Bend County in identifying any close contacts of the patient while he was sick so thaty can be isolated and monitored for symptoms and quickly tested, if needed. “Having a COVID-19 case in Texas is a significant development in this outbreak, but it doesn’t change the fact that the immediate risk to most Texans is low,” said Dr. John Hellerstedt, DSHS commissioner. “This travel-related case reinforces the fact that we should all be taking basic hygiene steps that are extremely effective in limiting limit the spread of COVID-19 and all respiratory illnesses.”DSHS says a travel-related case in Texas does not indicate spread within the state.Governor Abbott and the DSHS will hold a press conference Thursday on the state's testing capabilities for COVID-19. 1345
