CARLSBAD (CNS) - A Carlsbad man was behind bars Wednesday for allegedly killing his roommate.Patrol officers responding to a report of a death in the 2500 block of West Ranch Street at about 11:30 a.m. Tuesday found a 40-year-old woman dead in an apartment in the neighborhood near the intersection of El Camino Real and Tamarack Avenue, police said.Her name was withheld pending family notification.Detectives questioned the woman's roommate, 44-year-old Brehon Roy Quigley, then arrested him, Carlsbad police Lt. Jason Jackowski said. Quigley was booked into the county jail in Vista on suspicion of murder.Police declined to release details on how the victim died and would not disclose a suspected motive for the alleged slaying."The investigation into what occurred and why is ongoing," the lieutenant said. "No additional information is being released at this time." 880

CHICAGO, Ill. – A study published this month suggests that by lessening the amount of virus you take in by putting on a mask, you may also lessen the likelihood of getting severely sick if you contract COVID-19.As the race to a safe and effective coronavirus vaccine heats up, new research about masks is changing the narrative on their importance.Last week, CDC Director Dr. Robert Redfield called face masks the most “powerful public health tool we have.”“I might even go so far as to say that this face mask is more guaranteed to protect me against COVID than when I take a COVID vaccine,” said Dr. Redfield.It was a stark change from CDC messaging early on in the pandemic that face coverings would most likely only protect those around you.“That was because there was a lot of data at that time that you can shed the virus at high rates from your nose and mouth even when you feel well,” said Dr. Monica Gandhi, an infectious disease doctor and professor of medicine at the University of California – San Francisco.She co-authored newly published research in the New England Journal of Medicine that theorizes that not only do masks protect the wearer but they may even reduce the severity of the coronavirus when someone gets infected.“We realized that we should be messaging more strongly masks protect you as the wearer and protects others,” said Dr. Gandhi.It theoretically works much like the early days of vaccines that used small amounts of viruses to illicit an immune response in the body. So, by wearing a mask, you are only exposed to lesser amounts of the virus, if any, potentially building up a sort of immunity.“The more virus you get inside, the sicker you are, the less virus you have, the less sick you are. This is called a dose response and it's true of many infections,” said Dr. Emily Landon, an epidemiologist and infectious disease specialist at University of Chicago Medicine.Gandhi says the theory has already been studied and proven in animals.“There was a hamster study that looked at the COVID-19 virus and the more that the hamsters were given, the more sick they got,” she said.Dr. Gandhi says it could also explain the why according to the CDC, 40% of coronavirus patients are asymptomatic.“Countries that mask well have lower rates of severe illness than countries that don't mask well. So, putting it all together, this is our hypothesis.”And while the research is still theoretical, if it bears out, experts say universal mask-wearing could drive up the proportion of people who get less sick from the virus if they do contract it. 2579

CHICAGO, Ill. – Born in Mississippi, Syl Johnson rose to prominence as a velvet-voiced pop recording artist and producer in the 1950s and 60s. In recent years, he filed lawsuits against artists like Kanye West and Jay-Z for sampling his work. But it was his potent refrain about systemic racism in America, covered and sampled dozens of times, that continues to resonate today.It wasn’t until a decade into his musical career that the soul singer penned his most powerful single“I wrote it because that type of thing was happening to people and then they killed Dr. King,” said Johnson.It was the 1968 assassination of Dr. Martin Luther King Jr. That made him question the dream.The lyrics painfully questioning the black experience: “Looking back over my false dreams, that I once knew… Wondering why my dreams never came true… Is it because I'm Black?”“I didn’t want to write something that was militant,” said Johnson. “I wanted to write something that was truth. It was truth. Is it because I’m Black? It was.”Released in September 1969 “Is It Because I’m Black” struck a nerve.“In this world of no pity… I was raised in the ghetto of the city,” he sang.Call-in requests catapulted it to number 11 on the Billboard Soul Singles Chart in just weeks.Though, the Black concept album failed to find financial success, 50 years later, Johnson is now in his early 80s and seeing the resonance of his lyrics on the streets.“I didn’t know it would last this long,” he said. “But it looks like this song is the topic of the times. The times right now.”The killing of George Floyd, he says, is a response to the question he first posed – “Is it because I'm Black?”It is in the face of renewed examinations of race in America and calls for justice that Johnson is hopeful.“The younger whites and the younger Blacks should make it happen,” he said. “When they join together to make it happen, this world will be a beautiful place.”And one day he hopes the question won’t need to be asked. 1988

CAPE CANAVERAL, Fla. (AP) — The spacecraft team that brought us close-ups of Pluto will ring in the new year by exploring an even more distant and mysterious world.NASA's New Horizons spacecraft will zip past the scrawny, icy object nicknamed Ultima Thule (TOO-lee) soon after the stroke of midnight.One billion miles beyond Pluto and an astounding 4 billion miles from Earth (1.6 billion kilometers and 6.4 billion kilometers), Ultima Thule will be the farthest world ever explored by humankind. That's what makes this deep-freeze target so enticing; it's a preserved relic dating all the way back to our solar system's origin 4.5 billion years ago. No spacecraft has visited anything so primitive."What could be more exciting than that?" said project scientist Hal Weaver of Johns Hopkins University, part of the New Horizons team.Lead scientist Alan Stern of Southwest Research Institute in Boulder, Colorado, expects the New Year's encounter to be riskier and more difficult than the rendezvous with Pluto: The spacecraft is older, the target is smaller, the flyby is closer and the distance from us is greater.NEW HORIZONSNASA launched the spacecraft in 2006; it's about the size of a baby grand piano. It flew past Pluto in 2015, providing the first close-up views of the dwarf planet. With the wildly successful flyby behind them, mission planners won an extension from NASA and set their sights on a destination deep inside the Kuiper Belt. As distant as it is, Pluto is barely in the Kuiper Belt, the so-called Twilight Zone stretching beyond Neptune. Ultima Thule is in the Twilight Zone's heart.ULTIMA THULEThis Kuiper Belt object was discovered by the Hubble Space Telescope in 2014. Officially known as 2014 MU69, it got the nickname Ultima Thule in an online vote. In classic and medieval literature, Thule was the most distant, northernmost place beyond the known world. When New Horizons first glimpsed the rocky iceball in August it was just a dot. Good close-up pictures should be available the day after the flyby.ARE WE THERE YET?New Horizons will make its closest approach in the wee hours of Jan. 1 — 12:33 a.m. EST. The spacecraft will zoom within 2,200 miles (3,500 kilometers) of Ultima Thule, its seven science instruments going full blast. The coast should be clear: Scientists have yet to find any rings or moons around it that could batter the spacecraft. New Horizons hurtles through space at 31,500 mph (50,700 kph), and even something as minuscule as a grain of rice could demolish it. "There's some danger and some suspense," Stern said at a fall meeting of astronomers. It will take about 10 hours to get confirmation that the spacecraft completed — and survived — the encounter.POSSIBLY TWINSScientists speculate Ultima Thule could be two objects closely orbiting one another. If a solo act, it's likely 20 miles (32 kilometers) long at most. Envision a baked potato. "Cucumber, whatever. Pick your favorite vegetable," said astronomer Carey Lisse of Johns Hopkins. It could even be two bodies connected by a neck. If twins, each could be 9 miles to 12 miles (15 kilometers to 20 kilometers) in diameter.MAPPING MISSONScientists will map Ultima Thule every possible way. They anticipate impact craters, possibly also pits and sinkholes, but its surface also could prove to be smooth. As for color, Ultima Thule should be darker than coal, burned by eons of cosmic rays, with a reddish hue. Nothing is certain, though, including its orbit, so big that it takes almost 300 of our Earth years to circle the sun. Scientists say they know just enough about the orbit to intercept it.COMPARING FLYBYSNew Horizons will get considerably closer to Ultima Thule than it did to Pluto: 2,220 miles versus 7,770 miles (3,500 kilometers vs. 12,500 kilometers). At the same time, Ultima Thule is 100 times smaller than Pluto and therefore harder to track, making everything more challenging. It took 4 ? hours, each way, for flight controllers at Johns Hopkins' Applied Physics Lab in Laurel, Maryland, to get a message to or from New Horizons at Pluto. Compare that with more than six hours at Ultima Thule.WHAT'S NEXTIt will take almost two years for New Horizons to beam back all its data on Ultima Thule. A flyby of an even more distant world could be in the offing in the 2020s, if NASA approves another mission extension and the spacecraft remains healthy. At the very least, the nuclear-powered New Horizons will continue to observe objects from afar, as it pushes deeper into the Kuiper Belt. There are countless objects out there, waiting to be explored. 4591

Carnival Cruise Lines announced Thursday that they are canceling several cruises until early 2021 due to COVID-19.In a press release, the cruise line company said that all P&O Cruises to the Caribbean were canceled until Jan. 2021, and cruises from and to Southampton, Arcadia, and Aurora were canceled through February.P&O Cruises is part of the Carnival Corporation.“With evolving restrictions on travel from the UK, unfortunately, it is necessary to cancel these itineraries," P&O Cruises president Paul Ludlow said in the news release. "These further cancellations vary according to ship as well as complexity and length of itineraries, advice, and guidance regarding ports of call and current air availability for fly/cruises. We are continuing to monitor the overall situation closely and will certainly reintroduce cruises should the opportunity arise, and it is feasible to do so.”Carnival also stated that they were delaying the return of Carnival Paradise, Carnival Magic, Carnival Valor, and the Carnival Spirit until next year "after scheduled dry dock enhancements are completed in the first half of 2021.""This extended pause in our operations has also impacted shipyard availability, and we've had to reschedule required dry docks," Christine Duffy, president of Carnival Cruise Line in the release. "As we continue to work through issues related to our eventual return to operations, we are committed to providing our guests and travel agent partners with certainty where we can, although we regret disappointing our guests. We appreciate the continued support and understanding of our guests and hope to welcome them back onboard soon."According to the Washington Post, the cruise line company also plans to sell 18 ships, which makes up 23% of its fleet. 1792
