A Masai giraffe calf died on Tuesday at the Columbus Zoo in Ohio shortly after its mother, Cami, was given an emergency Cesarean section in an effort to save both the mother and calf. According to the Columbus Zoo, veterinarians and zoo staff recognized that Cami was going into labor Tuesday afternoon, but that the giraffe calf was presenting rear hooves first. The zoo said that it is rare for calves to survive when born rear hooves first.That is when a decision was made for veterinarians to enter Cami's stall. It also meant that a webcam of the birth broadcasted by National Geographic was shut off. Veterinarians from the zoo and Ohio State University first attempted to remove the calf manually. When that did not work, they performed the emergency Cesarean section.Unfortunately, their efforts were futile. "Cesarean sections in giraffes are extremely rare and typically conducted as a last resort due to the high risks involved in putting giraffes under anesthesia and successful recovery," the zoo said in a statement. "After the calf was extracted via Cesarean section, the veterinary team found that the calf had serious congenital defects and thus would not have survived even if it had been born front hooves first."The zoo said Cami’s condition was stable, but her prognosis remains guarded as of late Tuesday evening. Zoo staff will continue to monitor her condition. Tuesday's failed birth marks the second giraffe calf the zoo has lost in recent weeks. On November 17, Ubumwe, an 18-day-old calf died at the zoo. The cause of Ubumwe's death remains unknown, and a full pathology report is being conducted to determine the cause of death. According to information from the Association of Zoos and Aquariums, giraffe calves have a 25 percent mortality rate. This is compared to roughly a 50-percent mortality rate for giraffe calves born in the wild, according to the association.  2007

All overseas travelers, except mainland China, will have to quarantine in a hotel for 14 days upon arriving in Hong Kong, the government announced as COVID-19 cases continue to surge.The new changes will go into effect Nov. 3 and remain until further notice, government officials said in its coronavirus tab on its website.The government said anyone who has stayed in high-risk countries Bangladesh, Ethiopia, France, India, Indonesia, Kazakhstan, Nepal, Pakistan, the Philippines, Russia, South Africa, the United Kingdom, and the United States of America must provide the following documents upon arrival:A negative COVID-19 test result, in English or Chinese, was issued by a laboratory or healthcare institution 72 hours before landing in Hong Kong. Lab results must bear the traveler's identical name listed on their valid travel documents.Suppose the report isn't in English or Chinese. In that case, passengers must show a written confirmation in English or Chinese issued by the laboratory or healthcare institution with the same name as on travel documents. Must also present negative COVID-19 test results.Must prove in English or Chinese that laboratory or healthcare institution is ISO 15189 accreditedMust show you have reserved a hotel room in Hong Kong for no less than 14 days beginning the first day of arrival in Hong Kong.Failure to comply with said new guidelines will result in a ,000 fine or six months imprisonment, the government said.On Tuesday, Hong Kong's Centre for Health Protection reported nine new COVID-19 cases, bringing its total to 5,345. 1585

According to a recent paper, the Earth is caught directly in the crosshairs of a cosmic hurricane.A swarm of nearly 100 stars, accompanied by an even greater amount of dark matter, is aimed directly at our stellar neighborhood and there's nothing we can do to stop it; in fact, the vanguard is already upon us. This sounds like a perfect summer blockbuster movie, starring The Rock and Chris Pratt, or maybe Scarlett Johansson and Charlize Theron.Except this is for real. But is it a danger? Well, actually, no. Not at all. But it's potentially incredibly fascinating, with lots of interesting scientific interconnections. So, what is really going on?The story starts last April, when the Gaia satellite announced the locations and trajectories of 2 billion stars in the vicinity of the Milky Way surrounding our sun. They released the data to the public.Scientists were then able to look at the data set to see if they could spot anything peculiar. In galaxies like the Milky Way, the most common behavior is that the stars orbit the center of the galaxy in a manner broadly similar to the planets orbiting our sun. However, there are some stars that exhibit unusual motion. About a year ago, astronomers identified some "stellar streams" passing through our celestial neighborhood.One of them, called S1 (for stream 1), consists of nearly 100 stars of similar age and composition, orbiting the Milky Way in a direction exactly opposite that of normal stars. It's kind of like a handful of cars driving the wrong way down the highway, except with a much greater distance between them and with no likelihood of a collision. These stars are spread out over a few thousand light years and they will pass through the solar system's neighborhood over the course of a few million years.Astronomers identified S1 as being part of the remnants of a dwarf galaxy that collided with the Milky Way and was consumed in an epic episode of cosmic cannibalism. Dwarf galaxies are very small, typically about 1% the mass of the Milky Way. They can orbit larger galaxies and collide with the bigger galaxy, adding their mass to the parent. This is what appears to have happened in the case of S1, although the process has taken probably a billion years.Dwarf galaxies often have a disproportionately large fraction of dark matter. Dark matter is a hypothetical and still-undiscovered form of matter that interacts only gravitationally. Scientists have proposed its existence to explain many astronomical mysteries, for example the observation that most galaxies rotate faster than can be explained by the known laws of physics and the stars and gas of which they are composed.While dark matter has not yet been observed, hypothesizing its existence is the simplest and most economical explanation for myriad astronomical mysteries. Averaged over the entire universe, dark matter is thought to be five times more prevalent than the ordinary mass of stars and gas and planets.In dwarf galaxies, the fraction of dark matter is often higher. In Fornax, a well-studied dwarf galaxy orbiting the Milky Way, researchers estimate that the dark matter is between 10 and 100 times greater than the mass found in its stars.If that number holds for S1, the dark matter of the S1 stream is passing through the Earth at a much higher velocity than the more ordinary dark matter that orbits the Milky Way -- about twice as fast. It is thought that S1 dark matter is flying through the solar system at a speed of about 550 km/s, or about 1.2 million mph. While these numbers are impressive, they are misleading. Dark matter, if it exists, is extremely diffuse and it will have no discernible effect on the solar system.Because dark matter hasn't been observed yet, these velocity numbers are speculative, although they are strongly supported by a very large body of evidence. However, the prospect of high velocity dark matter flying through the Earth has suggested an opportunity to detect it.In a paper in the prestigious journal Physical Review D, researcher Ciaran O'Hare and his collaborators calculated the possibilities of discovering dark matter using both existing and proposed dark matter detectors. They considered two varieties of dark matter particles: a very heavy kind called a WIMP (weakly interacting massive particle) and a very light kind called an axion. Because the ultimate nature of dark matter is not known, it is important to be open to all possibilities.They found that the detectors they evaluated could find WIMPs for certain ranges of the particle mass. However, when they looked at the axion possibility, it appeared the prospects were even better. Because of its light mass and the manner in which an axion would interact with the detector, the apparatus simply has a better chance of seeing the axion. (If axions exist, of course.)Experiments with names like ADMX, MADMAX and ABRACADABRA are able or will be able to search for the signatures of dark matter proposed in the recent paper. They consist of technologies that are designed to interact with axions in a strong magnetic field and convert them to ordinary microwaves or radio waves that can be easily detected.It's important to remember that the S1 stream poses no credible threat to the Earth and humanity. There is no need for an action hero to save us. However, the synergy of science is staggering. A careful catalog of nearby stars has opened the prospect of a better possibility of finding and identifying dark matter, which is one of the great unanswered mysteries of modern physics. It's an amazing time we live in, in which we can study such things.\ 5625

Airport security checkpoints can be among the worst things about air travel. Most of us would like to have the TSA Pre-Check so we can skip the long lines and the wait, but the cost to have it processed steers us away from this travel perk.If you have a trip coming up this year, there is some good news. There's a way to get a free TSA Pre-Check membership.Right now, there are at least 12 credit cards and 5 loyalty programs that will let you get a TSA Pre-Check membership for free.The credit cards include certain American Express cards, Bank of America premium rewards, Chase Sapphire and Expedia Voyager card from Citi.The loyalty programs include Marriott rewards, United Mileage Plus and Club Carlson. We found, while many of the credit cards cover the TSA Pre-Check fee outright, the loyalty programs pay for it with points.You also need to consider if there's an annual fee for the credit card and if the tradeoff is worth it.Of course anytime you sign up for a credit card and or loyalty program you'll want to read the fine print, but it could be worth your while to check out your options to save some cash, and some time, when you travel.  1199

After asking for coronavirus-related deadline extensions in April, the Trump administration now appears to be abandoning that request by asking Congress for extra funding to wrap up the 2020 census “as quickly, and safely as possible” in a move that could help ensure the number-crunching for redrawing congressional districts takes place on President Donald Trump’s watch.Census Bureau officials had warned as recently as early July that it was already too late to have the numbers ready without an extension. And outside experts predicted Tuesday that speeding up the timetable would lead to an inaccurate head count that misses people in hard-to-count minority communities.“It would be like giving an expectant mother in the early stages of pregnancy a lot of money to have the baby in 4.5 months,” said John Thompson, a former Census Bureau director in the Obama administration.The Census Bureau is in the middle of the 2020 census, and some of the bureau’s 500,000 door-knockers started heading out this month to households that haven’t yet answered the questionnaire.With the new coronavirus disrupting census operations in April, the Trump administration asked Congress to extend the deadlines required for the U.S. Census Bureau to turn in the head count data used for redrawing congressional district and legislative districts. The Census Bureau also postponed finishing field operations for the 2020 census from the end of July to the end of October.The Democratic-controlled House agreed to the extensions as part of coronavirus-relief legislation, but the Republican-controlled Senate has yet to do so. Senate Republicans on Monday instead proposed an additional 8 million in funding for the 2020 census in its coronavirus-relief bill.“This funding would allow for additional hiring, staffing resources, and replenished contingency funding to provide schedule flexibility as the Census Bureau conducts its largest field operation, nonresponse followup,” the Census Bureau said Monday on its website. “This flexibility is critical to helping the Census Bureau operate in the midst of unprecedented public health crisis, including trying to wrap up field data collection as quickly, and safely as possible, while ensuring a complete and accurate count. “When asked about the status of the deadlines request, the office of Senate Majority Leader Mitch McConnell referred to existing policy for the census timeline and said it had nothing further to add.Historically, the Census Bureau is required to turn over numbers for apportionment, the process of divvying up congressional seats, by Dec. 31, and the numbers used for redrawing legislative districts by March 30. The deadline extensions would push back the apportionment deadline to April 30 and the redistricting deadline for state and local districts to July 31.If the deadline extension for the apportionment numbers is granted by Congress, there’s a chance the final months of the data-crunching would take place under a new administration if presumptive Democratic presidential nominee Joe Biden defeats Trump, a Republican, in the November election.Wary of what they see as Trump’s attempts to politicize the 2020 census, House Democrats say Senate Republicans should approve the request for deadline extensions.“Otherwise, American taxpayers would be forced to pay for the most expensive and potentially least accurate census in our nation’s history,” said U.S. Rep. Carolyn Maloney, a Democrat from New York who chairs the House Committee on Oversight and Reform.Earlier this month, House Democrats asked U.S. Commerce Secretary Wilbur Ross to withdraw two appointees from top positions at the U.S. Census Bureau, claiming they represented the latest effort by the Trump administration to politicize the 2020 census.Then last week, Trump issued a memorandum seeking to exclude people in the country illegally from being included during the process for redrawing congressional districts. Civil rights group have filed multiple lawsuits challenging the memorandum as unconstitutional and an attempt to limit the power of Latinos and immigrants of color. Two more lawsuits were filed Tuesday, including one by California Attorney General Xavier Becerra and several California cities, which said California stood to lose a congressional seat if Trump’s order succeeds.“The timing of the executive memorandum issued last week coupled with what now appears to be abandonment of the request to push back the reporting deadlines clearly suggests that the White House wants to ensure that the president receives the numbers for apportionment while he is still in office. It’s hard to draw any other conclusions,” said Terri Ann Lowenthal, a census expert who worked on census issues as a congressional aide.More than 62% of households had responded to the census as of Sunday, leaving about 55 million households that will require visits by census takers. A Pew Research Center survey taken in June highlights the difficulties already facing census takers, with 40% of adults who say they have not yet responded to the census answering that they wouldn’t be willing to open their door for a census taker.The Census Bureau said Monday that it will start sending out emails to residents in neighborhoods with low response rates, encouraging them to fill out the questionnaire.Talking to reporters at the beginning of the month, Al Fontenot, the bureau’s associate director for decennial programs, said the bureau was “past the window of being able to get those counts” by the end of the year.Kenneth Prewitt, who served as a Census Bureau director in the Clinton administration, said an accelerated census in the middle of a pandemic “can only be explained politically.”“I believe the odds of being able to produce the census between now and the end of the year is extremely low. COVID is in charge. The Census Bureau is not in charge,” Prewitt said. “To finish the census by the end of the year, COVID has got to go away, and it’s not.”___AP Congressional Correspondent Lisa Mascaro in Washington contributed to this report.___Follow Mike Schneider on Twitter at https://twitter.com/MikeSchneiderAP 6170
