Massive Saharan dust plume is heading for Florida as it drifts across Atlantic
Saharan dust is heading toward Florida and could be seen over the state by this weekend, radar shows.
Dust is forecast to hit south and central Florida on Saturday and stay for at least several days, according to CBS Miami's NEXT Weather radar.
Computer models show that after an initial dust wave, a larger and denser plume could be seen in Florida by the middle of next week, CBS Orlando affiliate WKMG reports.
Radar also shows dust over south Texas on Monday.
Saharan dust was already seen in Puerto Rico and the U.S. Virgin Islands this week, the National Weather Service in San Juan reported on Tuesday. It noted dust impacts included reduced visibility and hazy skies, and said more dust is forecast to move in Saturday and linger through at least Tuesday.
Satellite imagery showed dust above most of the Atlantic's tropical waters on Thursday — spanning all the way from Africa's coast to to the Gulf, the National Hurricane Center's Tropical Analysis and Forecast Branch said in a post on X. It noted that the dry air suppresses the development of storms. Hurricane season officially starts on Sunday.

It is typical for dust to move across the Atlantic every year in early summer, WKMG reports. The National Oceanic and Atmospheric Administration says it is called the Saharan Air Layer, which is "a mass of very dry, dusty air that forms over the Sahara Desert during the late spring, summer and early fall."
Its activity usually "ramps up" in the middle of June before peaking from late in the month to the middle of August, meteorologist Jason Dunion told NOAA's National Environmental Satellite, Data, and Information Service back in 2020. New "outbreaks" — formed when "ripples" in the atmosphere along the edge of the Sahara Desert kick up dust — can occur every few days and reach as far west as Florida and Texas. Dust sometimes covers areas over the Atlantic as large as the continental United States, Dunion said.
The National Weather service said the dust can impact allergies and lead to eye irritation.

CNN Poll: A record share of Americans want the government to get more done. Few trust either party to do it
Neither the Republican nor the Democratic Party has consolidated a majority of the public behind its approach, with more than 4 in 10 saying that neither party can get things done or has strong leadership, a new CNN survey conducted by SSRS finds. Despite those widespread doubts, Americans increasingly say they see meaningful differences between the two parties. The poll, taken as public opinion resettles in the first months of Donald Trump's second administration, also finds a record-high share of the public saying that the government should be doing more to solve problems. Americans are evenly split on which party best reflects their views on the role of the federal government, with one-third of respondents saying neither party does. Amid a wave of skepticism among Democrats about their own party's effectiveness, the GOP currently holds the advantage across several key attributes — though with a shrinking advantage on the economy, which regularly polls as Americans' top concern. Americans see Republicans and Democrats as offering vastly contrasting visions of the country. An 81% majority say they see important differences between the two parties, marking an increase from two years ago across political, age and educational lines. Just 18% say the parties are 'pretty much the same,' down from 28% in 2023 and roughly one-third in CNN and Gallup polling dating back to 2002. But even among those who say there are critical differences between the two major parties, a sizable minority say neither reflects their vision across a range of issues: Nearly 20% who see such differences still say neither party reflects their perspective on at least 5 out of 9 issues they were asked about in the poll. Asked to choose which of the parties they see as the 'party that can get things done,' 'the party with strong leaders' or the 'party of change,' the lion's share of the public – more than 4 in 10 – say that neither party fits the bill. At the same time, most Americans, 58%, now say that the government should do more to solve the country's problems – a record high in more than 30 years of CNN's polling. While Democratic views on the role of government have remained largely unchanged over the past two years, the shares of Republicans and independents who say that the government is doing too many things have both fallen since the White House changed hands. While neither political party is viewed as especially strong or effective, skepticism weighs particularly heavily on the Democratic Party. Americans are far more likely to see Republicans than Democrats as the party with strong leaders: 40% say this descriptor applies more to the GOP, with just 16% saying it applies to the Democrats. They're also more likely to call Republicans the party that can get things done by 36% to 19%, and the party of change, by 32% to 25%. That's in large part because of relatively anemic support for Democrats among their own partisans. GOP-aligned adults are 50 points likelier than Democratic-aligned adults to say their own party has strong leaders, and 36 points likelier to view their party as able to get things done. True independents, those who don't lean toward either party, are particularly grim in their views of the parties on these issues: 76% say neither party has strong leaders or can get things done, and 72% that they view neither as the party of change. While the public as a whole sees the GOP as relatively effective, they also say, 41% to 30%, that it's better described as the party of extremism, the only attribute tested that fewer than 30% said applied to neither party. Roughly one-sixth of Republican-aligned adults say they view the GOP as representing extremism, compared with roughly one-tenth of Democratic-aligned adults who say the same of their own party. Beyond Americans' shifting views of government, the survey also finds ebbing belief in the achievability of the American Dream. A 54% majority says that most people who want to get ahead can make it if they're willing to work hard, down from 67% in 2016, and lower than other polling on the same question dating back to the 1990s. Nearly half, 45%, say they don't view hard work and determination as any guarantee of success for most people. That rises to a 52% majority of Black Americans and 53% among those younger than 30, as well as 53% of those who don't agree with either party on the economy, 65% among Democrats and 71% among those who describe themselves as liberal. Americans are closely split on which party represents the middle class, with a third saying neither does. The view that neither party stands for the middle class rises to 38% among those who say hard work and determination are no guarantee of success for most people. Asked which party best reflects their views on handling the economy more broadly – a perennial top issue that has frequently favored the GOP – the public gives the Republican Party an advantage, but a shrinking one. The party's 7-point margin on the issue now is down from 15 points in May 2022, and marks their narrowest advantage on the issue over that time. The Republican Party also sees a diminished edge on immigration, another typically strong topic for the Trump-led party: What was a 14-point lead in November 2023 now stands at just 6 points. Looking outward, Americans are now evenly divided on which party's views on world affairs more closely match their own, an issue where Republicans held a 6-point edge in 2023. Across issues tested in the poll, Republicans held the widest advantage – 13 points – on their approach to crime and policing, and that margin has largely held over time. The public also leans modestly toward the GOP when it comes to taxes (by a 7-point margin) and the federal budget (5 points). Support for legal abortion remains strong in CNN's polling, with a rising share of the public, 36%, now saying that abortion should be legal under any circumstances. Roughly 6 in 10 Democrats now say abortion should always be legal, up from 44% in 2016. In a CNN survey last year, a roughly two-thirds majority of the public opposed the Supreme Court's decision to overturn Roe vs. Wade. By a 10-point margin, Americans say their views on abortion align more with the Democrats than the Republicans, although that's down from a 16-point advantage in fall 2023. Roughly two-thirds of Republicans and Republican-leaning independents say the GOP reflects their views on abortion – significantly lower than the share who side with their party on issues such as the economy or immigration. Amid internal Democratic arguments over the party's messaging on issues surrounding race and gender, the poll finds that Americans side with the Democratic Party over the Republican Party on the way society deals with LGBTQ issues by an 8-point margin and with racial issues and education by a 7-point margin each. By a wide margin, 72% to 27%, most Americans say that growing racial diversity does more to enrich than threaten American culture. That's slightly broader agreement than last fall, though it still falls short of the more than 8 in 10 who called diversity enriching during Trump's first term. The sense of diversity as a threat is largely concentrated among the GOP, particularly among Republican-aligned men. Currently, 45% of Republicans and Republican-leaning independents call diversity a threat, up from just 20% who said the same in 2019, during Trump's first term in office. Democratic opinion has moved little in that time. Democrats held their widest advantage in the poll, 14 points, on handling climate change. A 58% majority of adults say they're at least somewhat worried about the risks of climate change in their community, down slightly from the 63% who said they were at least somewhat worried in the fall of 2023. About one-quarter in each poll said they were very worried. By a 5-point margin, Americans say their view of how to protect U.S. democracy aligns more with the Democratic Party than the Republican Party. Roughly half of Americans say that democracy in the U.S. today is under attack, with 36% saying it's being tested, and only about 13% that it's not in any danger. While these concerns have held roughly steady since 2021, partisan dynamics have shifted sharply in that time. In the latest poll, 72% of Democrats see democracy in crisis, compared with just 29% of Republicans. By contrast, during Joe Biden's presidency, concerns were either roughly balanced or higher among the GOP. The CNN poll was conducted among 2,539 adults nationwide by SSRS from May 5-26, using a combination of online and telephone interviews. The survey samples were originally drawn from two sources – an address-based sample and a random-digit dial sample of prepaid cell phone numbers – and combined. Respondents were initially contacted by mail or by phone. Results for the full sample have a margin of sampling error of plus or minus 2.7 percentage points.

Discrimination cases unravel as Trump scraps core civil rights tenet
For decades, the federal government has used data analysis to ferret out race and sex discrimination, winning court cases and reaching settlements in housing, education, policing and across American life. Now the Trump administration is working to unwind those same cases. In recent weeks, the Justice Department backed out of an agreement with an Atlanta bank accused of systematically discouraging Black and Latino home buyers from applying for loans. The Education Department terminated an agreement with a South Dakota school district where Native American students were disciplined at higher rates than their White peers. And federal prosecutors have dropped several racial discrimination reform agreements involving state and local police departments — including that of Minneapolis, where George Floyd was murdered by an officer in 2020.

New research presents promising findings on colorectal cancer treatment and prevention
Colorectal cancer is the second most common cause of cancer deaths in the United States, according to the American Cancer Society. This year, the organization estimates that more than 150,000 Americans will be diagnosed with it and nearly 53,000 will die from it. New studies presented at the annual meeting of the American Society of Clinical Oncology, or ASCO, in the last few days offer promising findings for both pharmaceutical and lifestyle interventions, including the impact of diet and exercise. Diagnoses of colorectal cancer have been decreasing overall for decades, the American Cancer Society says, thanks in large part to better screening. But case rates are rising among younger adults, and research estimates that colorectal cancer will become the leading cause of cancer death among adults ages 20 to 49 by 2030. Earlier research has suggested that regular exercise can improve survival rates for colorectal cancer patients, and a new study – published in the New England Journal of Medicine and presented at the ASCO conference on Sunday – confirmed those findings with robust clinical trial data. Between 2009 and 2024, researchers followed nearly 900 colon cancer patients who had completed chemotherapy – half of whom received an informational booklet that encouraged them to adopt a healthy lifestyle with good nutrition and exercise the other half of whom were also matched with a physical activity consultant for three years. They found that there was a 28% reduction in the risk of recurrence or new cancer for patients on the exercise program, with a five-year disease-free survival rate of 80% for the group with an exercise consultant compared with 74% for the group who just received the booklet. In other words, the exercise program was found to prevent 1 out of every 16 patients from developing recurrent or new cancer. 'That magnitude is comparable to – and in many cases exceeds – the magnitude of benefit offered by a lot of our very good standard cancer drugs,' said Dr. Christopher Booth, a professor of oncology with Queen's University and co-author of the new study. 'Exercise really should be considered an essential component of treatment of colon cancer.' Work is still being done to understand why exercise can help reduce the risk of cancer, but experts say that it may have something to do with the ways exercise helps reduce inflammation in the body. Another new study presented at the ASCO conference on Sunday found that anti-inflammatory diets also helped improve survival rates for people with stage 3 colon cancer. Patients who consumed more anti-inflammatory diets – including coffee, tea and vegetables such as leafy greens – and engaged in higher levels of physical activity had a 63% lower risk of death compared to patients who consumed the most inflammatory diets – including things like red meat, processed meat, refined grains and sugar-sweetened beverages – and engaged in lower levels of physical activity, the study found. 'Actively, as a field, we're learning about the role of the immune system in cancer development, and inflammation is an immune response,' said Dr. Sara Char, a clinical fellow in Hematology and Oncology at Dana-Farber Cancer Institute and lead author of the study, and the rise of colorectal cancer cases in younger people suggests it's a critical piece of the puzzle. 'When we look at the incidence of colon cancer in younger individuals … that really suggests to us that there is something in the environment – either in the foods we eat, our lifestyles, the chemicals that could be in our foods, all sorts of different things – that are outside of just genetics alone that could be driving these rates,' she said. 'So it is incredibly important for us, as a field, to be thinking about how our diet and lifestyle impacts not just our risk of developing this cancer, but then how people fare after it.' Both Booth and Char said that colorectal cancer patients are often seeking ways to proactively manage their risk. 'I think that's it's very empowering for patients,' Booth said. 'It's also achievable for patients. This is a commitment, but it's something that patients can achieve.' In his study, an 'exercise prescription' was developed based on each individual's starting point. Most people were able to reach their target increase if they went for a brisk walk for about an hour three or four days per week, Booth said. Lifestyle interventions like exercise and diet are also 'sustainable for health systems,' he said, but it's key that the system helps support patients in accessing the resources needed for behavioral interventions. Another new study showed promising results that might represent a new standard-of-care for certain patients with advanced colon cancer. On Friday, drugmaker Pfizer presented data on a colorectal cancer drug, Braftovi, used in combination with a standard chemotherapy and an antibody drug. During the trial, the drug combo was shown to double the length of time patients with an aggressive form of colorectal cancer lived with treatment: an average of 30 months compared with 15 months using currently available treatments. Braftovi targets a mutation in a specific protein that can lead to abnormal cell growth, and it's already approved by the US Food and Drug Administration to treat some forms of cancer. The study, which was funded by Pfizer, published Friday in the New England Journal of Medicine. 'It's a targeted cancer therapy that really depends on knowing what's driving patients' cancer,' Pfizer CEO Dr. Albert Bourla told CNN. These targeted therapies are one of the biggest advancements in cancer treatment over the past two decades, he said, and it's easy to diagnose whether cancer patients have the specific mutation that Braftovi can treat. The latest data on treatment for colorectal cancer a 'very, very important finding,' Bourla said, and the drugmaker plans to seek additional approval to add the new indication to the drug's label.
