What did white children have to say about their “all-white” schools integrating? – Julia M.N., age 11, New York City

In 1954, the Supreme Court ruled in Brown v. Board of Education that racially segregated schools violated the civil rights of Black students. Black Americans throughout the country celebrated the decision as a blow to anti-Black racism.

Whites’ reactions to the case varied, depending on where they lived and whether their local communities had a history of segregation, either through laws or just local customs and practices. White students’ acceptance of this social change was significantly shaped by their parents’ political beliefs about school desegregation.

Stories of peaceful transition to integration are less known than stories of white defiance.

The Supreme Court case was named for a lawsuit that originated in Topeka, Kansas, in 1951, opposing public school segregation. The segregationist Topeka School Board was embarrassed by the publicity associated with the case because of the history of Kansas as a state where slavery was illegal. So eight months before the landmark Supreme Court decision, the board members reversed their prior stance, resolving “to terminate … segregation in the elementary schools as rapidly as is practicable,” according to meeting minutes.

Those records also showed that some white parents threatened to withdraw their children if they were expected to share classrooms with Black students or Black teachers.

Other white parents embraced the new desegregation policy, like the parents of Clay Elementary School student Nancy Jones. Jones’ parents advised her to “be friendly with the new students and to treat them with kindness and respect.”

Although Black students began attending integrated schools in Topeka in 1954, it wasn’t until 1957 that the city assigned Black teachers to predominantly white schools. And even then, anticipating what it called “social hazards,” the School Board let white parents choose whether they wanted their kids to only have white teachers or to let the district assign students and teachers without regard to race.

The parents of Randolph Elementary School student Mike Worswick were among those who chose the latter. It was a decision that indirectly supported the integration of Black teachers.

It turned out to be one of the best things of my life,” Worswick recalled in an interview years later.

Jones, whose parents had urged kindness, was upset when she found out about violence that erupted in other places across the nation.

We never saw anything like that in Topeka,” she recalled in 2019.

Americans’ collective historical memory of desegregation is filled with visual images of white resistance in Southern cities like Little Rock, Arkansas, in 1957 and northern cities like Boston in 1974.

One iconic photo was taken at Little Rock’s Central High School on Sept. 4, 1957. That day, Arkansas Gov. Orval Faubus ordered the Arkansas National Guard to block Black students’ entry into the school. Local newspaper photographer Will Counts photographed one of the Black students, 15-year-old Elizabeth Eckford, after she was turned away from school. Eckford was surrounded by white students in the picture, as one named Hazel Bryan, also 15, is yelling at her.

The picture quickly spread through national news outlets, and Bryan became the symbolic face of Southern white racism. The notoriety haunted Bryan, who apologized to Eckford five or six years later.

While Bryan and her fellow students became a public spectacle, the fact that most whites did nothing was less remarked upon.

White students who supported integration knew that if they came to Black students’ aid, they risked social repercussions, or worse. Central High junior Robin Woods was “ashamed” of her peers’ behavior outside of school that September day, but did not get involved. When a Black classmate forgot his math book that day, though, Woods shared hers. That act of kindness was met with a “gasp of disbelief,” and a year of harassment followed.

Central High School senior Marcia Webb also witnessed her peers’ aggression toward the integrating Black students, who became known as the “Little Rock Nine.” At the time she was more interested in high school dances and athletic events than the emerging political storm, a racial privilege that was denied her new Black classmates.

“I’m sorry to say now, looking back, that what was happening didn’t have more significance and I didn’t take more of an active role,” she recalled. “But I was interested in the things that most kids are.”

As an adult, Webb expressed regret for her unwillingness to intervene:

[H]urt can come from words, from silence even, from just being ignored.”

Trump administration blocked CDC transit mask mandate, report shows


The global outbreak of the coronavirus disease (COVID-19) continues, in New York City

Mon, October 17, 2022
By David Shepardson

WASHINGTON (Reuters) - Former President Donald Trump's administration at a crucial time in the COVID-19 pandemic in 2020 blocked the U.S. Centers for Disease Control and Prevention (CDC) from adopting a federal mandate requiring face masks on airline flights and other forms of transit, a congressional report released on Monday said.

Marty Cetron, a senior CDC official, is cited in the report as saying the federal public health agency began working on the proposed order in July 2020 after its experts determined that there was scientific evidence to support requiring masks in public and commercial transportation.

The report was released by a Democratic-led House of Representatives subcommittee examining pandemic-related issues.

The proposed order would have required masks on public and commercial transportation modes and hubs like airports, airplanes, trains and ride-sharing vehicles, Cetron said.

By July 2020, major airlines, regional transit systems and some airports had taken action on their own to mandate masks to try to curb the spread of COVID-19. But the report stated that CDC had heard from the transit industry that it wanted the federal government to issue a mandate.

Cetron, who heads the CDC's division of global migration and quarantine, said the agency was told by Trump administration officials that a mask requirement on mass transportation "would not happen," according to the report. Cetron also told the panel that masking requirements "could have made a significant contribution" to saving U.S. lives from COVID-19 in 2020.

The report quoted Cetron as saying Alex Azar and Robert Redfield, who at the time headed the U.S. Department of Health and Human Services and the CDC respectively, both had expressed support for the proposed order.

With more than a million deaths, the United States leads the world in reported COVID-19 fatalities. Democrats have accused Trump of overseeing a disjointed response to the pandemic. Trump himself was hospitalized with COVID-19 later in 2020.

Days after President Joe Biden took office in January 2021, the CDC issued a sweeping order requiring face masks on nearly all forms of public transportation.

Cetron, who remains at the CDC, and an agency spokesperson declined to comment on Monday.

Reuters reported in July 2020 that the Trump administration had held extensive talks about whether the CDC should issue an order requiring transportation masking. The Trump White House instead announced that it opposed any efforts by Congress to require masks in transit. Trump was seeking re-election at the time. Many U.S. conservatives opposed government mandates requiring masks during the pandemic.

Representative James Clyburn, who chairs the House committee, said the report shows that Trump's administration "engaged in an unprecedented campaign of political interference in the federal government's pandemic response, which undermined public health to benefit the former president's political goals."

The Biden administration's transportation mask mandates were challenged in court. A Florida-based federal judge in April declared the order unlawful and lifted it. The administration has appealed the ruling. A U.S. appeals court has tentatively set arguments in the case for January.

The House report also said Trump's administration rejected a CDC plan to extend a no-sail order for cruise ships through the winter of 2020-2021 and instead issued a conditional order requiring the cruise industry to complete incremental steps before resuming operations.

The report cited Redfield as saying then-Vice President Mike Pence made the decision not to extend the no-sail order following lobbying from the industry and its allies.

CDC officials describe intense pressure, job threats from Trump White House

Appointees of President Donald Trump oversaw a concerted effort to restrict immigration at the U.S.-Mexico border during the pandemic, change scientific reports and muzzle top officials at the Centers for Disease Control and Prevention, according to emails, text messages and interviews gathered by a congressional panel probing the pandemic response.

Former CDC director Robert Redfield, former top deputy Anne Schuchat and others described how the Trump White House and its allies repeatedly "bullied" staff, tried to rewrite their publications and threatened their jobs in an attempt to align the CDC with the more optimistic view of the pandemic espoused by Trump, the House select subcommittee on the coronavirus crisis concluded in a report released Monday.


Several public health officials detailed a months-long campaign against Schuchat sparked by Trump appointees' belief that her grim assessments of the pandemic reflected poorly on the president, leading Schuchat, a 32-year CDC veteran, to openly wonder whether she would be fired in the summer of 2020, her colleagues told the panel.

The panel's latest report also offers new insight into key flash points, such as a CDC-backed plan to require masks on public and commercial transportation in the summer of 2020, with Martin Cetron, director of the agency's division of global migration and quarantine, citing evidence that the requirement would have reduced coronavirus risks to travelers.

The plan was backed by the travel industry and "could have made a significant contribution" by curbing infections and deaths ahead of a fall and winter virus surge that year, Cetron added, but Trump officials blocked the measure. President Biden later issued a similar order in his second day in office in January 2021.

Redfield and other officials told the panel that they believed they might be fired if they angered the White House, hindering the CDC's ability to fight the virus.

"If we constantly are finger-pointing and blaming somebody else for things, we lose the fact that the real enemy here was the virus," Cetron said in a May 2022 interview included in the report, adding that political infighting hampered the pandemic response. Cetron also criticized a federal order, Title 42, that used the pandemic as a public health reason to bar people from entering the United States at its borders with Canada and Mexico as an example of a poorly constructed policy where CDC experts were overruled.

The order was "handed to us," Cetron told the panel, saying that then-White House adviser Stephen Miller was among the officials who discussed the immigration restrictions. Other emails and media reports have linked Miller to the order's creation.

While Cetron said he and his team opposed the order, arguing it lacked a scientific basis because the coronavirus was already widely spreading in the United States and could lead to harm for asylum seekers, Redfield signed Title 42 in March 2020. The Trump administration characterized the measure, which allows the government to immediately send asylum seekers back to their home countries, as a way to prevent the spread of infection in detention cells, at border stations and in other crowded settings. Hundreds of thousands of migrants have since been turned away at the U.S.-Mexico border. The measure remains in place under the Biden administration after a district court judge in May blocked the administration's plan to lift the order.

The panel's report draws on more than 2,100 pages of transcribed interviews with Redfield, Schuchat, Cetron and 10 other current and former CDC officials that were newly released on Monday, in addition to prior interviews and testimony from people such as former White House coronavirus coordinator Deborah Birx. The panel also released other documents, including a letter sent by a pair of former Trump appointees, Kyle McGowan and Amanda Campbell, who served as the CDC's chief of staff and deputy chief of staff, respectively, that detailed examples of political interference and poor treatment of CDC officials.

"The committee's report reflects a serious and fair look at what happened," McGowan said.

Rep. James E. Clyburn (D-S.C.), who chairs the panel, said that the report demonstrates how the Trump White House engaged in a concerted effort "to downplay the seriousness" of the pandemic.

"This prioritization of politics, contempt for science, and refusal to follow the advice of public health experts harmed the nation's ability to respond effectively to the coronavirus crisis and put Americans at risk," Clyburn said in a statement.

Clyburn's panel has spent more than two years investigating the Trump administration's pandemic response, issuing reports that detailed White House pressure on the Food and Drug Administration to authorize unproven coronavirus treatments such as the antimalarial drug hydroxychloroquine; its efforts to overrule public health officials on coronavirus guidance for churches; and exploring how its focus on challenging the 2020 election outcome distracted from the virus response, among other findings.

Republicans have assailed the panel's reports as partisan, saying it has neglected to probe Biden administration virus missteps or the origins of the pandemic. GOP leaders vow to conduct their own investigations next year should they win control of the House or Senate. CDC Director Rochelle Walensky also acknowledged this summer that her agency had made significant mistakes during the pandemic, laying out a plan intended to speed up its recommendations, improve its communications and take other steps to win back public trust.

The report also details how Trump appointees at the Department of Health and Human Services worked to wrest control of the agency's Morbidity and Mortality Weekly Reports, or MMWRs, which offer public updates on scientists' findings and had been considered off-limits to political appointees for decades.

McGowan and Campbell told the panel that fellow Trump appointees were angry about a May 2020 MMWR written by Schuchat that they believed did not give them sufficient credit for their efforts to contain the pandemic.

"Secretary [Alex] Azar, in particular, was upset and said that if the CDC would not get in line, then HHS would take control of approving the publication," McGowan and Campbell's lawyer wrote to the panel. As a result, Trump appointees increasingly received access to the CDC's draft summaries and sought to edit or block the reports, including one on the rise in hydroxychloroquine prescriptions that was held up for more than two months amid concerns it would call attention to an unproven treatment touted by Trump.

In a statement, Azar said that he "never pressured Dr. Redfield to modify the content of a single MMWR scientific article."

"I always regarded the MMWR and other peer-reviewed scientific publications as sacrosanct," Azar added, saying that he worked with Redfield to "protect the integrity" of the report's peer-review process after a "defect" was identified in May 2020. Azar did not specify the "defect" that needed to be addressed.

The panel concluded that Trump appointees had sought to "alter the contents, rebut, or delay the release" of 18 MMWRs and one health alert on an inflammation syndrome in children who had previously tested positive for the coronavirus, and succeeded at least five times.

CDC officials said the agency resisted the most significant efforts to edit their publications. "Was I concerned that there was an attempt to alter the scientific content of the MMWR? Yes. Do I think they were successful? No," Jay Butler, the CDC's deputy director of infectious diseases, told the panel in a November 2021 interview.

The panel also details repeated attempts by Trump appointees to pressure Schuchat, such as a personal phone call from then-White House Chief of Staff Mark Meadows - the first time any White House chief of staff had called the CDC deputy, she said - that left her "very shaken," she told the panel, declining to offer details of the call, on the advice of HHS counsel.

Meadows did not immediately reply to an email sent to a spokesperson.

Schuchat was again targeted after an interview she gave to a medical journal in June 2020 in which she acknowledged the nation's struggles in containing the virus. HHS spokesperson Michael Caputo and his adviser Paul Alexander circulated internal emails claiming the CDC deputy was attempting "to damage the president."

Other officials described interactions with Caputo and Alexander where the two men "threatened" staff, such as when a CDC official spoke to NPR without the HHS spokesperson's permission in July, the panel said. Caputo "wanted to terminate the CDC official who set up the interview," McGowan and Campbell's lawyer wrote to the panel.

Caputo declined a request for comment. Alexander did not immediately respond to a request for comment.

Redfield said that he repeatedly told Caputo that Alexander should stop his barrage of emails to staffers demanding changes to CDC publications and accusing them of working to undermine Trump. "I advocated to Caputo, probably around [late June], that he should get rid of this guy. He's not helpful," Redfield told the panel.

But Alexander's messages continued until mid-September, when his emails leaked to the press and Caputo subsequently accused CDC scientists of sedition in a Facebook Live video. Caputo took a medical leave on Sept. 16, and Alexander left the agency the same day.

Redfield also said he clashed with the White House and Florida politicians about his plan to reissue a "no-sail order" that would keep the nation's cruise ships in dock, given evidence that the coronavirus could rapidly spread aboard the vessels and sicken and potentially kill vulnerable passengers.

"I was signing it . . . [even] if that meant that I was resigning or being fired as CDC director," Redfield told the panel. He said he was eventually able to reach a compromise in October 2020 that kept the ships in dock until the cruise industry instituted more safety precautions.
Hair-straightening products linked with uterine cancer risk -study



Mon, October 17, 2022 

By Nancy Lapid

(Reuters) - Hair-straightening products may significantly increase the risk of developing uterine cancer among those who use them frequently, a large study published on Monday suggests.

"We estimated that 1.64% of women who never used hair straighteners would go on to develop uterine cancer by the age of 70, but for frequent users, that risk goes up to 4.05%," study leader Alexandra White of the U.S. National Institute of Environmental Health Safety (NIEHS) said in a statement.

"However, it is important to put this information into context. Uterine cancer is a relatively rare type of cancer," she added.

Still, uterine cancer is the most common gynecologic cancer in the United States, according to the U.S. Center for Disease Control and Prevention (CDC), with rates rising, particularly among Black women.

Researchers tracked 33,947 racially diverse women, ages 35 to 74, for an average of nearly 11 years. During that time, 378 women developed uterine cancer.

After accounting for participants' other risk factors, the odds of developing uterine cancer were more than two and a half times higher for women who had used straightening products more than four times in the previous year.

Less frequent straightener use in the past year also was associated with an elevated uterine cancer risk, but the difference was not statistically significant, meaning it might have been due to chance.

Earlier studies have shown that hair straighteners contain so-called endocrine disrupting chemicals. The products have previously been associated with higher risks of breast and ovarian cancer.

"These findings are the first epidemiologic evidence of association between use of straightening products and uterine cancer," White and colleagues wrote in The Journal of the National Cancer Institute. "More research is warranted to ... identify specific chemicals driving this observed association."

The link between straightener use and uterine cancer did not differ by race in the study.

But "because Black women use hair straightening or relaxer products more frequently and tend to initiate use at earlier ages than other races and ethnicities, these findings may be even more relevant for them," Che-Jung Chang of NIEHS said in a statement.

U.S. Supreme Court gives boost to Domino's in arbitration case


: A Domino's Pizza restaurant is seen in Los Angeles

By Daniel Wiessner

(Reuters) - The U.S. Supreme Court on Monday gave a boost to Domino's Pizza Inc's bid to force delivery drivers to bring a wage lawsuit in private arbitration rather than in court in a case from California that could have major implications for gig economy companies.

The justices threw out a lower court's ruling that had let a group of drivers pursue a class action lawsuit seeking to recoup work-related expenses because their local deliveries represented the final step in the flow of goods over state lines.

The justices ordered the San Francisco-based 9th U.S. Circuit Court of Appeals to reconsider the case in light of the Supreme Court's unanimous ruling in June that Southwest Airlines Co could not force an overtime pay lawsuit by baggage handlers into arbitration because the workers routinely load cargo onto planes that cross state lines.

A U.S. law called the Federal Arbitration Act requires the enforcement of agreements that workers sign with companies to bring legal disputes in arbitration, but it exempts transportation workers engaged in interstate commerce.

More than half of private-sector U.S. employees have signed arbitration agreements, which typically also bar class action claims. Business groups have called arbitration a quicker and more efficient alternative to suing in court. Workers' advocates have said that process tends to favor employers.

Three delivery drivers sued Domino's in California state court in Santa Ana in 2020, accusing the company of violating various wage laws, and the case was subsequently transferred to federal court.

Domino's made a motion to send the claims to arbitration, citing agreements that the drivers had signed barring them from suing in court. A federal judge in Santa Ana denied the motion, ruling that the drivers were exempt from arbitration because they were involved in interstate commerce.

The 9th Circuit last year upheld the judge's decision, finding that the drivers were integral in getting products that came from outside California to their final destinations. Domino's then appealed to the Supreme Court.

There has been a growing number of lawsuits filed in courts around the country asserting that local delivery drivers qualify for the interstate commerce exemption because they handle goods coming from other states such as various ingredients used to make Domino's pizza and other prepared foods.

The scope of the exemption has divided federal appeals courts in cases involving Grubhub Inc, Uber Technologies Inc and its subsidiary Postmates Inc, and Amazon.com Inc "last mile" delivery workers.

Up to 20 arrested after striking truckers block plant exits

PLYMPTON, Mass. (AP) — Striking truckers used tractor-trailers to block the exits at New England’s largest wholesale food distributor Monday and prevented some employees from leaving, resulting in as many as 20 arrests, police said.

More than 400 Teamster union members arrived at the Sysco facility in Plympton, Massachusetts, in the early morning and stopped about 100 employees from leaving, Police Chief Matthew Ahl said in a statement.

Police spent two hours negotiating with picketers.

“After the attempted negotiation to move union members out of the roadway to create a safe passable environment, unfortunately we had to respond by removing members of the crowd who were inciting a hostile picket line," the chief said.

Sixteen to 20 people were arrested on charges including disorderly conduct and assault and battery, he said. After the arrests, traffic started to flow safely.

About 300 Sysco drivers represented by the Teamsters Local 653 started their strike Oct. 1 seeking better pay and benefits. Voicemails seeking comment were left with union representatives.

Houston-based Sysco, which has distribution facilities across the country, supplies food to schools, hospitals, nursing homes and restaurants.

A Sysco spokesperson said in a statement Monday that the company remains committed to reaching a “competitive labor agreement" with Local 653.

“While we are disappointed in the Teamsters leadership’s ongoing decision to have our employees out on strike without letting them vote, we respect their right to do so under the law," the company said. “What we can’t respect is violence, disorderly conduct, intimidation, or threats, on or off the strike line, targeting our employees, vendors, customers, or the public."

The Sysco warehouse in Plympton, south of Boston, is still operating with third-party drivers. The facility stocks about 13,000 products, according to the company’s website.

Sysco employees at a company facility near Syracuse, New York, had also been on strike, but the sides reached an agreement last week.

Ute Indian Tribe Blasts Biden’s National Monument at Camp Hale



Isabella Rosario
Fri, October 14, 2022 

The Utah-based Ute Indian Tribe says the Biden administration failed to formally consult their government before designating Camp Hale-Continental Divide National Monument in Colorado this week--a process required by federal law.

In a news release Wednesday, tribal leaders called the decision "an act of genocide to attempt to erase the history and connection of the tribe to these lands."

"These new monuments are an abomination and demonstrate manifest disregard and disrespect of the Ute Indian Tribe's treaty rights and sovereign status as a federally recognized Indian Tribe," said Shaun Chapoose, chairman of the tribe's business committee and an Uncompahgre Band member.

Biden used his authority under the Antiquities Act to designate the new 53,804-acre monument, which includes Camp Hale, a former Army base where the 10th Mountain Division trained to fight in World War II. It is located within the homelands of the tribe's Uncompahgre Band, who were forced out of the area by the U.S. in 1880.

The Ute Indian Tribe is one of three Ute Nation tribes in the western U.S. with ancestral ties to the land. Both the Southern Ute and Ute Mountain Ute have spoken in favor of the monument and attended the proclamation ceremony on Wednesday.

Chapoose told the Associated Press that the White House only called his tribe about a potential monument at Camp Hale a week ago.

"What frustrated us is that they didn't want us there to comment, they wanted us there for the photo opp," Chapoose told the AP, adding that he was invited to the event, but left out of frustration. "I don't expect them to roll out a red carpet, but I expect a little common courtesy. If I'm just going to be one of the Indians that you want to photograph, I'm the wrong Indian to call."

A senior Biden administration official, who spoke on condition of anonymity, told the AP that officials met with each Ute tribe about the monument, and that the tribes all expressed support for it.

During his remarks on Wednesday, Biden mostly spoke of the site's historic significance to the U.S. military, but also acknowledged the Ute tribe's connection to the land.

"I'm also honored to be joined by several tribal leaders here, because this is your progeny, this magnificent land," Biden said. "These treasured lands tell the story of America. For thousands of years, tribal nations have been stewards of this sacred land, hunting game, foraging for medicinal plants, and maintaining a deep, spiritual bond with the land itself."

In their statement earlier this week, the Ute Indian Tribe reiterated their opinion that the U.S. should adopt a tribal consultation standard of free, prior, and informed consent. According to a 2021 White House report, many Indigenous leaders have criticized the current consultation process as a "box-checking exercise" that leaves tribes in the dark.

"The White House and the Administration have refused to recognize and uphold this international law principle as other developed nations with large Indigenous populations, such as Canada, have sought to do," Ute Indian Tribe leaders said in a statement. "Failing to abide by this international standard casts a cloud on the United States and diminishes its standing among the world's governments."


University of Tennessee dinosaur mummy provides new insight into soft tissue fossilization


College of Arts and Sciences

Peer-Reviewed Publication

UNIVERSITY OF TENNESSEE AT KNOXVILLE

In 2008, an Edmontosaurus mummy” arrived at the North Dakota Geological Survey where lab technicians began the process of removing sediment and preparing the specimen for paleontologists to investigate. Nicknamed “Dakota,” the mummy revealed several unexpected features, such as extensive areas of fossilized skin and the presence of a broad fingernail on the end of dinosaur’s ‘mitten-like’ hand.

A paper published in PLOS reveals that these bite and potential claw marks in its beautifully preserved skin defied paleontological conventions on how such fossils formed.

“Conventional wisdom was telling us that ‘Dakota’ shouldn’t exist,” said Stephanie Drumheller, lead author and paleontologist at the University of Tennessee, Knoxville. “We needed to figure out how dinosaur skin, which had clearly been partially eaten, still managed to survive long enough to be buried and fossilized.”

Traditional understanding was that very rapid burial after death was necessary for soft tissue to end up in the fossil record. Burial is a great way to slow down many of the processes that break down remains, including predation and scavenging.

“Dinosaur mummies, however, never fit very well in this model,” Drumheller said. “They often appeared dried out, as if they had been baking under the sun for some time.”

In addition, long-term exposure would also leave the remains vulnerable to scavenging, which was thought to destroy any chance for the soft tissues to fossilize.

Fortunately, the field of forensic anthropology provided an alternate explanation. Modern research into patterns of decomposition suggests that partial scavenging of a carcass can, somewhat unintuitively, help dry and preserve skin over longer periods of time, even when the other soft tissues have decayed.

Researchers took digital images of the inside of “Dakota” that revealed the skeleton was preserved with the empty skin deflated around and appressed to the bones. All of the other internal organs were missing, which meant the dinosaur’s carcass could have laid on the landscape for weeks to months before burial – plenty of time for the organs and muscles to be eaten or decompose and for the skin to dry out and deflate before it was buried in sand.

“Not only has ‘Dakota’ taught us that durable soft tissues like skin can be preserved on partially scavenged carcasses, but these soft tissues can also provide a unique source of information about the other animals that interacted with a carcass after death, said Clint Boyd, Senior Paleontologist at the North Dakota Geological Survey.

NASA's Lucy spacecraft prepares to swing by earth

Lucy spacecraft

On Oct. 16, at 7:04 a.m. EDT, NASA’s Lucy spacecraft, the first mission to the Jupiter Trojan asteroids, will skim the Earth’s atmosphere, passing a mere 220 miles (350 kilometers) above the surface. By sling-shotting past Earth on the first anniversary of its launch, Lucy will gain some of the orbital energy it needs to travel to this never-before-visited population of asteroids.

The Trojan asteroids are trapped in orbits around the Sun at the same distance as Jupiter, either far ahead of or behind the giant planet. Lucy is currently one year into a twelve-year voyage. This gravity assist will place Lucy on a new trajectory for a two-year orbit, at which time it will return to Earth for a second gravity assist. This second assist will give Lucy the energy it needs to cross the main asteroid belt, where it will observe asteroid Donaldjohanson, and then travel into the leading Trojan asteroid swarm. There, Lucy will fly past six Trojan asteroids: Eurybates and its satellite Queta, Polymele and its yet unnamed satellite, Leucus, and Orus. Lucy will then return to Earth for a third gravity assist in 2030 to re-target the spacecraft for a rendezvous with the Patroclus-Menoetius binary asteroid pair in the trailing Trojan asteroid swarm.

For this first gravity assist, Lucy will appear to approach Earth from the direction of the Sun. While this means that observers on Earth will not be able to see Lucy in the days before the event, Lucy will be able to take images of the nearly full Earth and Moon. Mission scientists will use these images to calibrate the instruments.

Lucy’s trajectory will bring the spacecraft very close to Earth, lower even than the International Space Station, which means that Lucy will pass through a region full of earth-orbiting satellites and debris. To ensure the safety of the spacecraft, NASA developed procedures to anticipate any potential hazard and, if needed, to execute a small maneuver to avoid a collision.

“The Lucy team has prepared two different maneuvers,” says Coralie Adam, Lucy deputy navigation team chief from KinetX Aerospace in Simi Valley, California. “If the team detects that Lucy is at risk of colliding with a satellite or piece of debris, then--12 hours before the closest approach to Earth --the spacecraft will execute one of these, altering the time of closest approach by either two or four seconds. This is a small correction, but it is enough to avoid a potentially catastrophic collision.”

Lucy will be passing the Earth at such a low altitude that the team had to include the effect of atmospheric drag when designing this flyby. Lucy’s large solar arrays increase this effect.

“In the original plan, Lucy was actually going to pass about 30 miles closer to the Earth,” says Rich Burns, Lucy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “However, when it became clear that we might have to execute this flyby with one of the solar arrays unlatched, we chose to use a bit of our fuel reserves so that the spacecraft passes the Earth at a slightly higher altitude, reducing the disturbance from the atmospheric drag on the spacecraft’s solar arrays.”

At around 6:55 a.m. EDT, Lucy will first be visible to observers on the ground in Western Australia (6:55 p.m. for those observers). Lucy will quickly pass overhead, clearly visible to the naked eye for a few minutes before disappearing at 7:02 a.m. EDT as the spacecraft passes into the Earth’s shadow. Lucy will continue over the Pacific Ocean in darkness and emerge from the Earth’s shadow at 7:26 a.m. EDT. If the clouds cooperate, sky watchers in the western United States should be able to get a view of Lucy with the aid of binoculars.

“The last time we saw the spacecraft, it was being enclosed in the payload fairing in Florida,” said Hal Levison, Lucy principal investigator at the Southwest Research Institute (SwRI) Boulder, Colorado office. “It is exciting that we will be able to stand here in Colorado and see the spacecraft again. And this time Lucy will be in the sky.”

Lucy will then rapidly recede from the Earth’s vicinity, passing by the Moon and taking a few more calibration images before continuing out into interplanetary space.

“I’m especially excited by the final few images that Lucy will take of the Moon,” said John Spencer, acting deputy project scientist at SwRI. “Counting craters to understand the collisional history of the Trojan asteroids is key to the science that Lucy will carry out, and this will be the first opportunity to calibrate Lucy’s ability to detect craters by comparing it to previous observations of the Moon by other space missions.”

The public is invited to join the #WaveToLucy social media campaign by posting images of themselves waving towards the spacecraft and tagging the @NASASolarSystem account. Additionally, if you are in an area where Lucy will be visible, take a photograph of Lucy and post it to social media with the #SpotTheSpacecraft hashtag. Instructions for observing Lucy from your location are available here.

Hal Levison of Southwest Research Institute (SwRI), in the Boulder Colorado office is the principal investigator. SwRI, headquartered in San Antonio, also leads the science team and the mission’s science observation planning and data processing. NASA Goddard provides overall mission management, systems engineering and the safety and mission assurance for Lucy. Lockheed Martin Space in Littleton, Colorado built the spacecraft, principally designed the orbital trajectory and is providing flight operations. Goddard and KinetX Aerospace are responsible for navigating the Lucy spacecraft. Lucy is the thirteenth mission in NASA’s Discovery Program, which is managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama.

NASA’s Lucy to Fly Past Thousands of Objects for Earth Gravity Assist

Mission engineers will track NASA’s Lucy spacecraft nonstop as it prepares to swoop near Earth on Oct. 16 to use this planet’s gravity to set itself on a course toward the Jupiter Trojan asteroids.

But they also will be closely tracking something else: more than 47,000 satellites, debris, and other objects circling our planet. A greater than 1-10,000 chance that Lucy will collide with one of these objects will require mission engineers to slightly adjust the spacecraft’s trajectory.

Although an adjustment is unlikely, and collisions are rare, the chances are increasing as the number of objects in Earth’s orbit grows, NASA experts say.

The International Space Station, for instance, has maneuvered out of the way of space debris 31 times since 1999, including three times since 2020.

“Low-Earth orbit is getting more crowded, so that has to be part of the consideration nowadays, especially for missions that fly low, like Lucy,” said Dr. Dolan Highsmith, chief engineer for the Conjunction Assessment Risk Analysis group at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The group determines the probabilities of collisions between NASA’s robotic spacecraft and Earth-orbiting objects. NASA’s Johnson Space Center in Houston does the same for crewed spacecraft, such as the space station.

Launched on Oct. 16, 2021, Lucy is on a 12-year-journey to study multiple Trojan asteroids up close. It’ll be the first spacecraft to visit these remnants from the early solar system, helping scientists hone their theories on how the planets formed 4.5 billion years ago and why they ended up in their current configuration.

But Lucy has a long way to go before it arrives at the Trojans in 2027. The upcoming gravity assist is one of three the spacecraft will rely on to catapult itself to its deep-space targets.

When Lucy comes nearest to Earth for its first gravity assist it will cruise 220 miles (350 km) above the surface. That’s lower than the altitude of the space station and low enough that the spacecraft will be visible with the naked eye from western Australia for a few minutes starting at 6:55 p.m. local time (10:55 UTC). On its way down, Lucy will fly through the most crowded layer of Earth’s orbit, which is monitored by the U.S. Space Force’s 18th Space Control Squadron. The squadron helps NASA identify close approaches.

Engineers began collision analysis for Lucy a week before the spacecraft’s Earth approach. Starting the process any earlier would render collision predictions futile, Highsmith said: “The further you're predicting into the future, the more uncertain you are about where an object is going to be.”

Determining the positions of spacecraft, plus orbiting satellites and debris, is challenging, particularly when trying to anticipate the future. Largely that’s because the Sun plays a major role in pulling or pushing objects around, and future solar activity is hard to predict. For example, the Sun’s activity — how much plasma and radiation it shoots out — affects atmosphere density, and thus how much friction will tug on a spacecraft and slow it down.

So the closer the collision assessment is to the Earth flyby time, the better. NASA sends Lucy’s whereabouts to the Space Force squadron daily. If the squadron determines that Lucy could intersect with something, Highsmith’s group will calculate the probability of a collision and work with the mission team to move the spacecraft, if necessary.

With such a high value mission, you really need to make sure that you have the capability, in case it's a bad day, to get out of the way,” Highsmith said.

Lucy navigation engineers have two maneuver options ready in case the spacecraft needs to avoid an object. Both maneuvers require engine burns to speed up the spacecraft, which is traveling about 8 miles (12 km) per second. Each maneuver can move Lucy’s closest approach to Earth up by 2 seconds or 4 seconds, respectively.

“That's enough to avoid any one thing that could be in the way,” said Kevin E. Berry, Lucy’s flight dynamics team lead from NASA Goddard.

Hospital emergency departments lack policy and strategies for spotting child neglect or abuse


Reports and Proceedings

EUROPEAN SOCIETY FOR EMERGENCY MEDICINE

Berlin, Germany: In a survey of emergency department staff from across Europe, only around half said their hospital has a policy in place to help staff identify children who are being neglected or abused.

The research, presented at the European Emergency Medicine Congress [1], also shows that hospitals with such a policy are more likely to use strategies that are known to be effective in identifying children who are maltreated, including screening tools and staff training.

The study was presented by Féline Hoedeman, a PhD and medical student at the Erasmus MC Sophia Children’s Hospital in Rotterdam, The Netherlands. She said: “Abuse and neglect have devastating effects on children, families and society, but they can be very difficult to spot. Children who sustain injuries due to abuse are likely to present at an emergency department and previous research shows that staff can play an important part in identifying these children, especially if they have the right training, tools and resources.”

In collaboration with the Dutch Augeo Foundation, the European Society for Emergency Medicine (EUSEM), Research in European Paediatric Emergency Medicine (REPEM) network and the European Society of Emergency Nursing (EuSEN), the researchers from the Erasmus MC Sophia Children’s Hospital conducted a survey of healthcare professionals working in European emergency departments. The responses came from staff at 148 hospitals in 29 countries: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Kosovo, Latvia, Lithuania, Malta, The Netherlands, Norway, Poland, Romania, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

Only 51% of respondents said their hospital had a standardised child maltreatment policy. Twenty-four percent said they did not have such a policy. The remaining 25% either did not know or did not say whether they had a policy.

Those who said there was a policy were also more likely to report that their hospital had a child maltreatment screening tool (52% compared to 2% in hospitals without a policy), training on identifying maltreated children (63% compared with 30%), a child abuse team (73% compared with 27%) and a child maltreatment policy officer (51% compared to 20%). However, only 28% with a policy said that their hospital used all four of these strategies.

The researchers caution that the responses came from individual professionals and so are not representative of all hospital staff. 

Ms Hoedeman said: “Our study suggests that there are some hospitals where the right action is being taken to protect children. However, it also suggests that there are far too many hospitals where policy on child abuse and neglect is not in place or staff do not know the policy is there. Where that’s the case, staff are less likely to have the tools and knowledge they need and may be missing opportunities to help vulnerable children.”

The researchers plan to develop a toolkit, consisting of a hospital policy, training and a screening tool, to help identify children being neglected or abused. They have just completed a follow-up survey to investigate any factors that could help or hinder implementation of the toolkit.

Professor Youri Yordanov from the St Antoine Hospital emergency department, APHP Paris, France, is Chair of the EUSEM 2022 abstract committee and was not involved in the research. He says: “We know that having protocols and structured processes in hospitals can reduce medical errors and benefit patients. This study affirms that having a policy can support emergency department staff to spot children who are at risk.

“Although regulations and legal systems differ between European countries, the core components of a child maltreatment hospital policy should always be in place and can be adapted to different hospitals. We are starting to recognise that there is a lot of variability between hospitals when it comes to recognising child abuse and neglect and that’s something we need to urgently address.”

Marijuana-dependent patients at higher risk for infection after knee or shoulder arthroscopy procedures

Although more research is needed, physicians should discuss the potential risk of marijuana dependence with candidates for arthroscopy procedures

Key takeaways 

  • A higher infection rate found by new research should raise a “red flag” for patients and providers and should be discussed along with other risk factors before an arthroscopic procedure.  

  • Higher rates of deep vein thrombosis (DVT) were also found among these patients, but the study’s analysis determined they were not statistically significant. 

  • The study has identified the need for additional research to better understand the relationship between marijuana dependence and potential postoperative complications. 

SAN DIEGO: Patients who are dependent on marijuana may face higher infection rates following knee and shoulder arthroscopy—a minimally invasive surgery in which a small camera is inserted to diagnose and sometimes treat injury—according to a study presented at the Scientific Forum of the American College of Surgeons (ACS) Clinical Congress 2022. 

Using PearlDiver, a national insurance claims database, researchers from the University of Chicago performed a retrospective study of patients with marijuana dependence who underwent knee or shoulder arthroscopy for the postoperative complications of deep vein thrombosis (DVT), pulmonary embolism (PE), and infection.  

“Marijuana has been gaining so much popularity, but it’s a risk factor we aren’t really catching,” said lead study author Sarah Bhattacharjee, MD, who conducted the research while she was a medical student at the University of Chicago. Dr. Bhattacharjee is now a surgical resident in orthopaedic and sports medicine at the University of Washington. “The higher infection rate found by this new study should raise a ‘red flag’ for patients and providers and should be discussed along with other risk factors before an arthroscopic procedure.” 

Although the effect of marijuana use has been studied in pain management and cardiovascular health, few studies have looked at the potential effects of marijuana use by patients who are undergoing surgery. More states are legalizing marijuana, and the size of the cannabis market is predicted to reach $91.5 billion by 2028.1 Given that trend, the team of researchers from the University of Chicago set out to determine if marijuana-dependent users face an increased risk of complications following knee or shoulder arthroscopy.  

“There’s so much information out there on smoking, alcohol, and other substances, but not on marijuana use,” said study coauthor Jason Strelzow, MD, assistant professor of orthopaedic surgery, University of Chicago. “As providers and surgeons, we should be discussing marijuana use with our patients, something that we have traditionally shied away from.” 

Study details 

All patients undergoing knee or shoulder arthroscopy were identified retrospectively in PearlDiver. Next, patients who had a diagnostic code for marijuana dependence were also identified within each surgery category; this is a rigid definition requiring patients to three or more criteria, such as using marijuana longer than intended, difficulty in cutting down use, spending a lot of time in obtaining or recovering from marijuana, and high tolerance.  

The rates of DVT, PE, and infection within 90 days were assessed for all patients. Univariate analyses of marijuana dependence on all outcomes were performed, followed by a multivariate logistic regression analysis controlling for known patient comorbidities (other medical conditions).

Key findings 

  • The researchers identified 1,113,944 knee and 747,938 shoulder arthroscopy patients. Out of those 1,861,892 patients, 21,823 patients had a diagnostic code for marijuana dependence.  

  • Within both subgroups, the marijuana dependence cohort experienced increased rates of infection and DVT, while the PE rate stayed the same.  For the shoulder arthroscopy group, the rates of infection increased from 0.7%  to 1.7%, the DVT rate from 0.2% to 0.4%, while PE stayed at 0.2%. In the knee arthroscopy group, the rates of infection increased from 1.1% to 2.6%, the DVT rate rose from 0.2 to 0.3%, and PE stayed at 0.3%.   

  • In the multivariate analyses controlling for a variety of patient risk factors, including tobacco use or a history of diabetes, marijuana dependence was identified as an independent risk factor for infection within both cohorts. In this study, a statistical measure called a p-value (‘p’ stands for probability) was used to determine if the detected relationship was due to chance (p-values of 0.001 or below) or did, in fact, exist (p-values above 0.001). For the knee group, the p-value was 1.85, and for the shoulder group it was 1.65. 

(Note: The presenting author reported on updated data from the podium during the conference reflecting stable PE rates.) 

Dr. Strelzow hopes surgeons will use the study results to help inform marijuana-dependent patients about risks, benefits, and available alternatives, such as reducing or eliminating marijuana use six months prior to an arthroscopic procedure. 

Although the study focused on minimally invasive surgery, Dr. Strelzow said that “we would expect similar or larger effects with more open or invasive procedures.” 

Future research opportunities 

The study has identified the need for additional research to better understand the relationship between marijuana dependence and postoperative complications. In addition, given that the study used very rigid criteria for marijuana dependence, there are opportunities for future clinical studies to investigate how various levels of marijuana use impact postoperative complications.  Dr. Strelzow said he plans to study the impact of marijuana dependence on fracture healing.
