After a 29-year-old man drove a truck into a Manhattan crowd on Tuesday, killing eight and wounding almost a dozen in the deadliest terror attack to hit the city since 9/11, New Yorkers made it clear that they refused to be intimidated.Families celebrated a traditional Halloween Parade hours after the attack, surrounded by police officers armed with long guns while dozens of local and federal law enforcement officers were still investigating the attack."This was an act of terror, and a particularly cowardly act of terror," New York Mayor Bill de Blasio said, "aimed at innocent civilians, aimed at people going about their lives who had no idea what was about to hit them." 687

ABBEVILLE, La. (AP) — Hurricane Delta sped up one Louisiana couple's wedding by a few days but judging by the smiles on the bride and groom it certainly didn't dampen the affair. Ian and Taylor Gaspard from Abbeville were supposed to get married on Saturday, Oct. 10. But Hurricane Delta had other plans. After watching the hurricane slowly make its way toward Louisiana they swiftly changed gears and held the wedding Thursday with friends and family in attendance. The streets outside were largely deserted as residents finished up last-minute storm preparations or evacuated. The smiling bride said the ceremony was "beautiful."Hurricane Delta made landfall Friday at 6 p.m. CT near Creole, Louisiana, as a category 2 hurricane. 739

ALBANY, N.Y. (WKBW) — The New York State United Teachers are holding a press conference on Thursday calling for a strengthened statewide mask mandate in schools, which includes masks to be worn at all times in school.The teachers union says it will release a letter to the state Department of Health calling for revised school reopening guidance.“The governor has said — and we agree — that parents and educators must be confident in their school district’s reopening plan in order for this to work,” NYSUT President Andy Pallotta said. “As we hear of disparate mask procedures and other issues in reopening plans across the state, it’s clear that the state must step in. Making masks mandatory at all times is one step toward helping address the reservations that still exist regarding reopening school buildings.”The union says the only time masks are not needed are for appropriate break periods and in cases of medical accommodation.This story originally reported by Paul Ross on WKBW.com. 1002

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

Alan Bean, the fourth person to walk on the moon and the last surviving member of the Apollo 12 mission, died Saturday in Houston, according to his family and NASA. He was 86."Alan was the strongest and kindest man I ever knew," his wife, Leslie Bean, said in a statement. "He was the love of my life and I miss him dearly." She added he died "peacefully ... surrounded by those who loved him."The retired astronaut fell ill two weeks ago while traveling in Fort Wayne, Indiana, the statement said.Born on March 15, 1932, in Wheeler, Texas, Bean was a test pilot in the US Navy when NASA selected him and 13 others in October 1963 for training to become the third group of NASA astronauts, according to the family obituary shared by the space agency.His first mission to space was in November 1969 as a member of the Apollo 12 crew, the second to land on the moon, it said. He became the fourth man -- and one of only 12 in history -- to walk on the moon.Bean also commanded the second crewed flight to the first US space station Skylab in July 1973."In total, Bean logged 69 days, 15 hours and 45 minutes in space," the obituary said, "including 31 hours and 31 minutes on the moon's surface."After retiring from the Navy in 1975 and NASA in 1981, respectively, Bean became an artist and focused his energy on painting artistic impressions of the moon landing.According to NASA, Bean based that decision on his nearly two decades of experience as an astronaut "during which he visited places and saw things no artist's eye had ever seen firsthand. He said he hoped to capture those experiences through his art."The-CNN-Wire 1632
