Urgent action needed to address climate change’s catastrophic threats, U.N. report warns

Published

Individuals’s lives and Earth’s ecosystems are at growing danger of disaster if nations fail to shortly scale back emissions of planet-heating gases, in keeping with a brand new United Nations report that urges humankind to scale up efforts to adapt and shield essentially the most weak.

As world warming continues to unleash lethal warmth waves, intense droughts, floods and devastating wildfires, researchers from 67 international locations known as for pressing motion to handle the disaster. They stated lots of the harmful and accelerating results can nonetheless be diminished, relying on how shortly the burning of fossil fuels and emissions of greenhouse gases are curbed.

“Individuals and the planet are getting clobbered by local weather change. Practically half of humanity resides within the hazard zone — now. Many ecosystems are on the level of no return — now,” U.N. Secretary-Normal António Guterres stated. He known as the report “an atlas of human struggling” and an indictment of failed management. “The world’s largest polluters are responsible of arson of our solely dwelling.”

The report, which was launched Monday by the Intergovernmental Panel on Local weather Change, or IPCC, paperwork how climate-driven climate extremes have uncovered thousands and thousands of individuals to water shortages, worsening disasters and acute meals insecurity, and the way lots of the planet’s surviving species are weak to world warming.

The scientists stated the fates of pure ecosystems and human populations are interconnected, that safeguarding nature is essential to addressing local weather change and that about 3.3 billion to three.6 billion folks worldwide are extremely weak.

“The scientific proof is unequivocal: Local weather change is a menace to human well-being and the well being of the planet,” stated Hans-Otto Pörtner, co-chair of the IPCC Working Group II, which ready the report. “Any additional delay in concerted world motion will miss a quick and quickly closing window to safe a livable future.”

The report, which was ready by 270 authors and accepted by 195 member governments, focuses on local weather change’s results on folks and nature, and examines vulnerabilities and methods of adapting to make sure the planet’s survivability for future generations. The researchers stated populations particularly in danger are unfold throughout the globe and embody many in Africa, Asia, Central and South America, in addition to island nations.

In Central America, for instance, farmers have been fighting extra intense rainfall in addition to worsening dry spells, stated Edwin Castellanos, an IPCC writer from Guatemala.

“They’re shedding their crops because the rainfall doesn’t come to water their fields when anticipated. Adaptation efforts want to handle these points for all,” Castellanos stated. “Placing weak teams and international locations on the coronary heart of the decision-making course of on how we reply to local weather change could make societies extra resilient. We have to keep in mind that we’re a part of the character that surrounds us, and never its homeowners.”

Report authors stated adaptation efforts can embody restoring pure floodplains to scale back flood dangers, planting timber to chill city areas, bettering cropland administration, bettering water-use effectivity, strengthening well being packages to arrange for excessive warmth, and conserving mangroves and different wetlands as pure defenses towards coastal flooding.

Castellanos and different scientists famous that in 2009, rich international locations dedicated to mobilizing $100 billion per 12 months to handle the wants of creating international locations by 2020, a objective they’ve but to realize.

By 2050, that price might attain $295 billion per 12 months, researchers stated.

With the rise in world common floor temperatures of about 1.1 levels Celsius (2 levels Fahrenheit) up to now, damaging results are occurring extra quickly and with better severity than had been projected beforehand, researchers stated. They known as for governments, companies and people to take fast steps to satisfy the objective of limiting warming to 1.5 levels Celsius (2.7 levels Fahrenheit) above pre-industrial ranges, which they stated would “considerably scale back projected losses and damages” for people and ecosystems.

However reaching that objective requires slicing greenhouse-gas emissions 45% by 2030 and shifting towards net-zero emissions by 2050, Guterres stated. Sadly, the world is shifting in the wrong way, with emissions on observe to extend about 14% inside a decade. Guterres urged the rich international locations to close down coal-fired energy crops and speed up the transition to wash vitality.

The scientists careworn there will likely be grave penalties if the world stays on the present trajectory of rising temperatures. If the environment warms 2 levels Celsius (3.6 levels Fahrenheit), they stated, areas that rely on snowmelt might see a 20% drop in water availability by midcentury, which might devastate agriculture and depart many affected by meals shortages and starvation.

They stated local weather change has already “induced substantial damages, and more and more irreversible losses” in ecosystems on land, in freshwater and within the oceans, together with mass die-offs of timber in excessive droughts and warm-water bleaching occasions which have ravaged coral reefs.

About half the species which have been assessed worldwide have shifted towards the poles or to increased elevations, the report stated. The heating of the planet has pushed tons of of native losses of species and has accelerated the tempo of extinctions.

Camille Parmesan, lead writer of a chapter on ecosystems, stated ecological degradation via forest insect pest outbreaks, main wildfires, the thawing of permafrost and the drying of peatlands are “beginning to weaken the power of the biosphere to behave as a sink of greenhouse gases that people are emitting.”

A key factors that stands out within the science, Parmesan stated, is that people’ well being and resiliency rely on pure ecosystems.

“We’re seeing that holding local weather change right down to the decrease ranges goes to depend on getting pure techniques in higher form to suck up carbon, as a result of emissions reductions alone aren’t going to do it,” Parmesan stated.

The researchers stated that protected areas worldwide cowl lower than 15% of the land, 21% of the freshwater and eight% of the ocean. Latest analyses have recommended conserving 30% to 50% of the Earth’s land and waters to keep up their resilience.

Excessive warmth waves have killed rising numbers of individuals lately, the report stated, and the altering local weather has taken a worsening toll on folks’s well being in numerous methods, together with increasing areas the place illnesses like dengue can unfold and bringing psychological well being challenges to these experiencing trauma or nervousness concerning the planetary disaster. Extreme storms and flooding have additionally struck with extra depth, claiming lives and displacing folks.

“Persons are struggling and dying proper now from local weather change, and we’re not seeing an funding to try to ensure that we’re ready for a fair hotter future,” stated Kristie Ebi, lead writer of the report’s chapter on well being and a professor on the College of Washington. She stated there are numerous efficient choices for adapting and serving to communities higher put together, however little or no adaptation funding has gone towards well being.

Ebi referred to the lethal 2021 warmth wave within the Pacific Northwest and stated it underscores the necessity to put together for extra such extremes.

“No one must die in a warmth wave,” Ebi stated. “It’s critically vital to begin taking a look at these will increase in excessive climate and local weather occasions, wanting on the folks in hurt’s approach, largely the poor and the marginalized, and ensuring that efforts are undertaken to guard and promote well being and well-being in these communities.”

Ebi and different researchers famous that the burning of coal and oil causes hazardous air air pollution that results in respiratory illnesses and untimely deaths. So slicing that air pollution, they stated, would convey main well being advantages, and each increment of decreasing carbon emissions helps dial down world warming.

“Each motion issues,” Ebi stated, whether or not that’s in transportation, vitality effectivity or well-insulated buildings. “There are thousands and thousands of the way we will scale back our greenhouse gasoline emissions.”

The scientists stated world warming has already worsened water shortage, harmed meals manufacturing and battered cities and infrastructure.

They stated cities, the place greater than half the world’s inhabitants lives, face local weather dangers but additionally current huge alternatives for local weather motion, equivalent to creating non-polluting transit techniques and discovering options to chill neighborhoods the place paved areas are trapping warmth and creating the so-called city heat-island impact.

The report says many individuals on the planet’s rural areas are very weak to local weather change, and that social packages, “together with money transfers and public works packages,” can be utilized to assist as a part of adaptation efforts.

The report, a part of the Intergovernmental Panel on Local weather Change’s Sixth Evaluation Report, examines local weather adaptation choices and says contemplating conventional Indigenous data and native data is significant in creating options. The authors stated as a result of local weather change exacerbates present inequalities, selections and funding ought to focus additionally on fairness and justice, and scale back dangers for low-income and marginalized teams which might be most weak.

Whereas taking steps on the native degree to grow to be extra resilient, the researchers stated, the world should additionally tackle the losses and damages being attributable to the warming that has already occurred.

“For low-lying and coastal communities, the growing depth of tropical storms and hurricanes mixed with sea degree rise will lead to losses and damages, regardless of our greatest efforts to adapt,” stated Adelle Thomas, a report writer from the Bahamas. “And sadly, these unfavorable impacts of local weather change have disproportionate results on these which might be least capable of reply, the poorest and most weak communities.”

The researchers stated underlying causes for vulnerability embody financial inequity, colonialism and marginalization associated to poverty, gender or ethnicity, and that many Indigenous peoples are particularly weak. They stated those that endure in climate-fueled droughts, floods and storms typically embody individuals who reside in poverty with out fundamental providers, in addition to individuals who rely on subsistence farming or fishing.

From 2010-20, the report stated, deaths from floods, storms and droughts have been “15 occasions increased in extremely weak areas, in comparison with areas with very low vulnerability.”

In North America, the researchers stated, local weather change has already affected agricultural productiveness and is projected to scale back yields of crops equivalent to wheat, corn and soybeans.

Within the western U.S. and Mexico, the report stated, heavy exploitation of restricted water provides has compounded water dangers, whereas intensified droughts and diminished snowpack will improve water shortage, significantly in areas with intensive irrigated agriculture.

In current analysis, different scientists have discovered that western North America, from Montana to Northern Mexico, has been struggling via the driest 22-year interval in at the very least 1,200 years, and that the “megadrought” is being considerably worsened by increased temperatures with local weather change.

California is in a 3rd 12 months of utmost drought, and researchers have estimated that the state’s agriculture trade final 12 months shrank by an estimated 8,700 jobs whereas 395,000 acres of cropland have been left dry and unplanted due to the shortage of water.

The IPCC report says local weather change is predicted to proceed to shift the appropriate areas the place crops will develop in North America, and can proceed to “intensify manufacturing losses of key crops.”

“We discover that each elevated quantity of warming will improve the danger of extreme impacts,” stated Rachel Bezner Kerr, a professor of world growth at Cornell College and lead writer of a chapter on meals. “And so the extra fast we will take sturdy motion to scale back greenhouse gasoline emissions, the much less the extreme impacts will likely be.”

By detailing the most recent science, the report units the stage for the following U.N. local weather convention, which will likely be held in November in Sharm El-Sheikh, Egypt.

IPCC Chair Hoesung Lee stated the report is “a dire warning concerning the penalties of inaction” that lays out a “blueprint for our future on this planet.”

John F. Kerry, President Biden’s particular envoy for local weather, stated the report reveals the key results which might be already occurring, and “the horrible dangers to our planet if we proceed to disregard science.”

“The query at this level is just not whether or not we will altogether keep away from the disaster — it’s whether or not we will keep away from the worst penalties,” Kerry stated in an announcement. “Even because the world should proceed to do all the things doable to restrict world temperature rise, each within the quick and long run, we should additionally put together for the impacts that may arrive with that hotter planet.”

Column: Democrats show that they're no better than Trump in allowing politics to interfere with science

Column: Democrats show that they're no better than Trump in allowing politics to interfere with science

Anyone who cares about the importance of science in the making of government policy had to be deeply dispirited by the hearing into the origins of COVID-19 staged by a Republican-led House subcommittee on May 1.

The sole witness at the hearing, and its target, was Peter Daszak, the head of EcoHealth Alliance, a nongovernmental organization tasked with overseeing international virus research funded by federal agencies.

It wasn’t just that the GOP majority used the occasion to promote the ignorant, imbecilic and 100% evidence-free notion that SARS-CoV-2, the virus that caused the COVID pandemic, originated in a Chinese laboratory, through work funded by the U.S. government, and overseen by EcoHealth.

Science is a myth-buster…Because of this, science has become a nuisance, even an enemy to some industries and many of the most powerful actors in the new attention economy.

— Science blogger Philipp Markolin

It was that the Democratic minority showed itself to be complicit with the GOP attack on EcoHealth.

As I wrote at the time, the Democrats threw Daszak and by extension science itself under the bus: “Perhaps they hoped that by allowing Daszak to be drawn and quartered, they might persuade the Republicans to climb down from their evidence-free claims about government complicity in the pandemic’s origins.”

The Democrats’ craven and shameful performance hinted that EcoHealth’s government funding, which had been blocked by the Trump administration and restored, though delayed, under Biden, was pretty much doomed.

Advertisement

On Wednesday, the bell tolled. EcoHealth received a notice from the Department of Health and Human Services, the parent agency of the NIH, that it was immediately suspending all funding to the organization and moving to “debar” it from federal funding going forward.

It’s impossible to overstate what a serious blow this is for EcoHealth and research into the origins of pathogens that could cause illness and death on a global scale — the central purpose of EcoHealth’s work.

The organization, which has operated with a budget of about $16 million, cannot receive a contract from any federal agency or even serve as a subcontractor of another awardee. All organizations with federal contracts that have affiliated with EcoHealth will be “carefully examined.”

EcoHealth says it will appeal the proposed debarment, as is its right. But that process could take years. In the meantime, the organization will be effectively out of money, and very likely out of business. The HHS action effectively turns one of the leading organizations in the quest to protect humankind from the next pandemic into a pariah, completely unjustifiably.

The debarment threat “will mean the demise of EcoHealth, one of the most scientifically productive and internationally respected groups conducting field surveillance for potential pandemic viruses,” says Gerald T. Keusch, a former associate director of international research at the NIH. “And that means our national security will be compromised.”

Let’s be clear about what has happened here. EcoHealth has been made a scapegoat for the pandemic for partisan reasons. The process started with President Trump. At a news conference on April 17, 2020, a reporter from a right-wing organization mentioned that the NIH had given a $3.7-million grant to the Wuhan Institute of Virology. (Actually, the WIV grant, which was channeled from a larger EcoHealth grant, was only $600,000.)

Trump, sensing an opportunity to show a strong hand against China and advance his effort to blame the Chinese for the pandemic, responded: “We will end that grant very quickly.” The NIH terminated the grant one week later, prompting a backlash from the scientific community, including an open letter signed by 77 Nobel laureates who saw the action as a flagrantly partisan interference in government funding of scientific research.

The HHS inspector general found the termination to be “improper.” The NIH reinstated the grant, but immediately suspended it until EcoHealth met several conditions that were manifestly beyond its capability, as they involved its demanding information from the Chinese government that it had no right to receive. The grant was reinstated last year under Biden, but NIH bureaucrats, perhaps worried about their careers in a new Trump administration, continued to put administrative obstacles in the way of EcoHealth’s work.

The attacks on Daszak and his organization are simply instruments of the GOP project to pin blame for the pandemic on Anthony Fauci, one of the world’s most respected public health figures.

The context is a battle for the minds of uninformed and misinformed Americans over the origin of COVID-19. The hypothesis favored by most qualified virologists and epidemiologists is that the virus reached humans the way most viruses do — as spillovers from wildlife. The alternative hypothesis, for which absolutely not a speck of evidence has ever been presented, is that the virus emerged from a laboratory—specifically the Wuhan Institute of Virology in China, whether deliberately or through sloppy lab practices.

The latter hypothesis was initially promoted by an anti-China cabal in the Trump-era State Department. Although they never produced any grounds for the conspiracy theory, it remains favored by anti-vaccine agitators and in the Republican anti-science camp. It has a certain appeal for uninformed people susceptible to sinister explanations of complicated, troubling events; but it’s not science.

Daszak calls the government actions “fundamentally unfair” and “based on a set of false assumptions about COVID-19 origins and on persistent mischaracterizations and misunderstandings of our research…Our work has been at the forefront of understanding pandemic risk for over two decades, and it’s a very cruel irony that because we knew that China was a potential hotspot for the next coronavirus pandemic, we’re now being targeted in a political backlash caused by exactly the type of pandemic we were concerned about preventing.”

An outgrowth of the lab-leak fantasy is the asinine claim that as head of the National Institute of Allergy and Infectious Diseases, Fauci funded research in China that created the pandemic virus and let it loose on the world, and then concealed his complicity. This is a favorite meme among lab-leak fanatics. Among the research bodies that received NIAID funding to conduct field work in China was EcoHealth. (Fauci retired last year as director of NIAID, which is part of the National Institutes of Health.)

On May 1, the GOP-led Select Subcommittee on the Coronavirus Pandemic brought things to a head with its grilling of Daszak. It was a circus featuring posturing politicians intent on smearing Daszak and EcoHealth on the pretext of getting to the bottom of the pandemic’s cause. The committee Democrats participated fully, hammering Daszak as a “poor steward of the taxpayers’ dollars,” based on transparent trivialities.

During a follow-up subcommittee hearing Thursday, ranking member Raul Ruiz (D-Indio) alluded to the dishonestly of the GOP attack on Fauci. But, perhaps inadvertently, he also exposed the dishonesty of his caucus’ attack on Daszak.

The committee Republicans, Ruiz said, “still have not succeeded in substantiating their allegations that NIH and NIAID through a grant to EcoHealth Alliance created SARS-CoV-2 and conspired to cover it up. … No evidence demonstrates that work performed under the EcoHealth grants, including at the Wuhan Institute of Virology, led to the creation of SARS-CoV-2.”

Does Ruiz ever listen to the words coming out of his mouth? The very goal of the GOP’s dragging Daszak and EcoHealth into this controversy was to fabricate a link in the chain between Fauci and COVID-19; by rejecting the GOP position, Ruiz demolished the case against EcoHealth.

Yet Ruiz didn’t walk the last mile. “EcoHealth has defied its obligations to be a transparent steward of taxpayer dollars,” he said, repeated the lame case against the organization that he first aired, in connivance with the Republicans, during the public interrogation of Daszak on May 1.

Legitimate scientists, such as virology experts uninfected by the conspiratorial fantasy that the virus originated in the lab, are aghast at the suspension of EcoHealth’s funding and the organization’s likely debarment, as well as the Democrats’ supine behavior.

The Democrats, as Stuart Neil, a professor of virology at Kings College London, wrote on X, “have made some shoddy back room deal to allow them to look tough to the conspiracy theorists.” Neil is right. There is no rational explanation for the Democrats’ behavior than some sort of deal with the Republican majority to give them cover to challenge the lab leak theory.

Put it all together, and it looks like HHS started with a politically driven impulse to cut off EcoHealth’s funding, followed by an effort to assemble every justification for doing so, no matter how trivial. The absurdity of its action drips from the closing words of the notice issued by H. Katrina Brisbon, an HHS “suspension and debarment official.” She wrote that “the immediate suspension of EHA is necessary to protect the public interest and due to a cause of so serious or compelling a nature that it affects EHA’s present responsibility.”

The notice was accompanied by an 11-page bill of particulars, but they all boil down to two key purported offenses — that EcoHealth had missed a 2019 deadline for an annual report of its activities to NIH, and that work EcoHealth had funded in China had produced a recombinant version of a virus that grew fast enough to trigger a safety halt in the work.

The first was tantamount to a traffic violation. EcoHealth maintained that it hadn’t been able to file the report on time because it had been locked out of NIH’s onlline reporting portal, which NIH denies. On the second, there were legitimate disagreements over whether the subject virus’ growth actually did trigger the halt requirement; in any case, the virus wasn’t a threat to human health. The work at issue took place in 2018.

HHS cited several other supposed offenses, including EcoHealth’s failure to submit lab notebooks from the Wuhan institute that NIH has requested in November 2021. But since NIH had ordered EcoHealth to stop funding the institute as of April 2020, those notebooks were plainly out of its reach.

Daszak says EcoHealth will respond to the HHS and the subcommittee “with documentary evidence…refuting every single allegation that’s been levied against us.”

The roots of anti-science slant of Trump and others on the far right isn’t hard to discern. It’s aimed at protecting the economic establishment from new ideas and realities such as global warming, while providing financial and personal opportunities for grifters and charlatans.

Swiss scientist and science blogger Philipp Markolin has put his finger on this phenomenon.

“Science is a myth-buster,” he writes. “Its debunking activity reduces the value of information products that too many media manipulators rely on for their business. Because of this, science has become a nuisance, even an enemy to some industries and many of the most powerful actors in the new attention economy.”

Why did the Democrats agree to participate in this charade? In joining the Daszak smear, they have shredded their credibility as of scientific truth, at the very moment when science is most in need of their protection.

The time has come to ask this question of Ruiz, his Democratic colleagues on the coronavirus subcommittee — Debbie Dingell of Michigan, Kwesi Mfume of Maryland, Deborah Ross of North Carolina, Robert Garcia of Long Beach, Ami Bera of Sacramento and Jill Tokuda of Hawaii — along with Health and Human Services Secretary Xavier Becerra: How can you live with yourselves?

Star USC scientist faces scrutiny — retracted papers and a paused drug trial

Star USC scientist faces scrutiny — retracted papers and a paused drug trial

Late last year, a group of whistleblowers submitted a report to the National Institutes of Health that questioned the integrity of a celebrated USC neuroscientist’s research and the safety of an experimental stroke treatment his company was developing.

NIH has since paused clinical trials for 3K3A-APC, a stroke drug sponsored by ZZ Biotech, a Houston-based company co-founded by Berislav V. Zlokovic, professor and chair of the department of physiology and neuroscience at the Keck School of Medicine of USC.

Three of Zlokovic’s research papers have been retracted by the journal that published them because of problems with their data or images. Journals have issued corrections for seven more papers in which Zlokovic is the only common author, with one receiving a second correction after the new supplied data were found to have problems as well.

For an 11th paper co-authored by Zlokovic the journal Nature Medicine issued an expression of concern, a note journals append to articles when they have reason to believe there may be a problem with the paper but have not conclusively proven so. Since Zlokovic and his co-authors no longer had the original data for one of the questioned figures, the editors wrote, “[r]eaders are therefore alerted to interpret these results with caution.”

“It’s quite unusual to see this volume of retractions, corrections and expressions of concern, especially in high-tier influential papers,” said Dr. Matthew Schrag, an assistant professor of neurology at Vanderbilt who co-authored the whistleblower report independently of his work at the university.

Both Zlokovic and representatives for USC declined to comment, citing an ongoing review initiated in the wake of the allegations, which were first reported in the journal Science.

“USC takes any allegations of research integrity very seriously,” the university said in a statement. “Consistent with federal regulations and USC policies, this review must be kept confidential.”

Zlokovic “remains committed to cooperating with and respecting that process, although it is unfortunately required due to allegations that are based on incorrect information and faulty premises,” his attorney Alfredo X. Jarrin wrote in an email.

Regarding the articles, “corrections and retractions are a normal and necessary part of the scientific post-publication process,” Jarrin wrote.

Authors of the whistleblower report and academic integrity experts challenged that assertion.

“If these are honest errors, then the authors should be able to show the actual original data,” said Elisabeth Bik, a microbiologist and scientific integrity consultant who co-wrote the whistleblower report. “It is totally human to make errors, but there are a lot of errors found in these papers. And some of the findings are suggestive of image manipulation.”

Given the staid pace of academic publishing, publishing this many corrections and retractions only a few months after the initial concerns were raised “is, bizarrely, pretty quick,” said Ivan Oransky, co-founder of Retraction Watch.

The whistleblower report submitted to NIH identified allegedly doctored images and data in 35 research papers in which Zlokovic was the sole common author.

“There had been rumblings about things not being reproducible [in Zlokovic’s research] for quite some time,” Schrag said. “The real motivation to speak publicly is that some of his work reached a stage where it was being used to justify clinical trials. And I think that when you have data that may be unreliable as the foundation for that kind of an experiment, the stakes are just so much higher. You’re talking about patients who are often at the most vulnerable medical moment of their life.”

Over the years, Zlokovic has created several biotech companies aimed at commercializing his scientific work. In 2007, he co-founded ZZ Biotech, which has been working to gain federal approval of 3K3A-APC.

The drug is intended to minimize the bleeding and subsequent brain damage that can occur after an ischemic stroke, in which a blood clot forms in an artery leading to the brain.

In 2022, USC’s Keck School of Medicine received from NIH the first $4 million of a planned $30-million grant to conduct Phase III trials of the experimental stroke treatment on 1,400 people.

In Phase II of the trial, which was published in 2018 and called Rhapsody, six of the 66 patients who received 3K3A-APC died in the first week after their stroke, compared to one person among the 44 patients who got a placebo. Patients who received the drug also tended to report more disability 90 days after their stroke than those who got the placebo. The differences between the two groups were not statistically significant and could have been due to chance, and the death rate for patients in both groups evened out one month after the initial stroke.

“The statements that there is a risk in this trial is false,” said Patrick Lyden, a USC neurologist and stroke expert who was employed by Cedars-Sinai at the time of the trial. Zlokovic worked with Lyden as a co-investigator on the study.

One correction has been issued to the paper describing the Phase II results, fixing an extra line in a data table that shifted some numbers to the wrong columns. “This mistake is mine. It’s not anybody else’s. I didn’t catch it in multiple readings,” Lyden said, adding that he noticed the error and was already working on the correction when the journal contacted him about it.

He disputed that the trial represented any undue risk to patients.

“I believe it’s safe, especially when you consider that the purpose of Rhapsody was to find a dose — the maximum dose — that was tolerated by the patients without risk, and the Rhapsody trial succeeded in doing that. We did not find any dose that was too high to limit proceeding to Phase III. It’s time to proceed with Phase III.”

Schrag stressed that the whistleblowers did not find evidence of manipulated data in the report from the Phase II trial. But given the errors and alleged data manipulation in Zlokovic’s earlier work, he said, it’s appropriate to scrutinize a clinical trial that would administer the product of his research to people in life-threatening situations.

In the Phase II data, “there’s a coherent pattern of [patient] outcomes trending in the wrong direction. There’s a signal in early mortality … there’s a trend toward worse disability numbers” for patients who received the drug instead of a placebo, he said.

None are “conclusive proof of harm,” he said. But “when you’re seeing a red flag or a trend in the clinical trial, I would tend to give that more weight in the setting of serious ethical concerns around the pre-clinical data.”

The NIH paused the clinical trial in November, and it remains on hold, said Dr. Pooja Khatr, principal investigator of the NIH StrokeNet National Coordinating Center. Khatr declined to comment on the pause or the trial’s future, referring further questions to USC and NIH.

The NIH Office of Extramural Research declined to discuss Rhapsody or Zlokovic, citing confidentiality regarding grant deliberations.

ZZ Biotech Chief Executive Kent Pryor, who in 2022 called the drug “a potential game-changer,” said he had no comment or information on the halted trial.

Zlokovic is a leading researcher on the blood-brain barrier, with particular interest in its role in stroke and dementia. He received his medical degree and doctorate in physiology at the University of Belgrade and joined the faculty at USC’s Keck School of Medicine after several fellowships in London. A polyglot and amateur opera singer, Zlokovic left USC and spent 11 years at the University of Rochester before returning in 2011. He was appointed director of USC’s Zilkha Neurogenetic Institute the following year.

What military doctors can teach us about power in the United States

What military doctors can teach us about power in the United States

Power is invisible, but its effects can be seen everywhere — especially in the health records of active duty military personnel.

By examining details of 1.5 million emergency room visits at U.S. military hospitals nationwide, researchers found that doctors invested significantly more resources in patients who outranked them than in patients of equal or lesser rank. The additional clinical effort devoted to powerful patients came at the expense of junior patients, who received worse care and were more likely to become seriously ill.

Military rank wasn’t the only form of power that translated into inequitable treatment. The researchers documented that patients fared better when they shared the same race or gender as their doctor, a pattern that tended to favor white men and caused Black patients in particular to be shortchanged by their physicians.

The results were published Thursday in the journal Science.

The findings have implications far beyond the realm of the military, said Manasvini Singh, a health and behavioral economist at Carnegie Mellon University who conducted the research with Stephen D. Schwab, an organizational health economist at the University of Texas at San Antonio.

For instance, they can help explain why Black students do better in school when they are taught by Black teachers, and why Black defendants get more even-handed treatment from Black judges.

“We think our results speak to many settings,” Singh said.

The disparities wrought by power imbalances are easy to spot but difficult to study in real-world scenarios.

“It’s just hard to measure power,” Singh said. “It’s abstract, it’s complicated.”

That’s where the military health records come in.

The Military Health System operates 51 hospitals across the country. The doctors who staff them are active-duty personnel, as are many of the patients they treat. Comparing their ranks gave Singh and Schwab a handy way to gauge the power differential between physicians and the people in their care.

The researchers restricted their analysis to patients who sought treatment in emergency departments, where patients are randomly assigned to doctors. That randomness made it easier to measure how power influenced the treatment patients received.

To further isolate the effects of power, the researchers made comparisons between patients of the same rank. If they happened to outrank their doctor, they were considered a “high-power” patient. If not, they were classified as a “low-power” patient.

The medical records showed that doctors put 3.6% more effort into treating high-power patients than low-power ones. They also utilized significantly more resources such as clinical tests, scans and procedures, according to the study.

Those extra resources translated into better care: High-power patients were 15% less likely to become sick enough to be admitted to the hospital over the next 30 days.

To see if they could replicate their results, Singh and Schwab narrowed their focus to doctors who treated patients within a one-year period before or after the patients were promoted to a higher rank. The researchers found that doctors devoted 1% more effort to patients post-promotion, as well as more medical resources. Those differences may have been small, but they were statistically significant, Schwab said.

Next, the pair considered what happened to low-power patients while high-power patients were getting extra attention. One hypothesis was that ordering additional tests for one patient might prompt doctors to order the same tests for everyone they treated that day. It was also possible that the decisions doctors made for their high-power patients had no bearing on their other patients.

Neither turned out to be the case. Instead, the added effort spent on high-power patients was siphoned away from low-power patients, who got 1.9% less effort from their doctors. On top of that, their risk of needing to return to the ER or be admitted to the hospital over the following 30 days increased by 3.4%, the researchers found.

“The powerful unwittingly ‘steal’ resources from less-powerful individuals,” Schwab and Singh wrote.

Outside the military, doctors and patients can’t use official rank to measure their power relative to each other, but they do contend with the effects of race and gender. That led the researchers to investigate whether the physicians in their study treated patients differently if they shared these attributes.

White doctors devoted more effort to white patients than to Black patients across the board, the researchers found. The gap was the same regardless of whether the doctor had a higher or lower rank than the patient.

However, white doctors increased their effort for high-power patients by the same amount regardless of race. As a result, white doctors treated high-power Black patients the same, on average, as low-power white patients.

The story was different for Black doctors. When they outranked their patients, they gave essentially the same amount of effort to everyone. But on the rare occasions when they encountered a higher-ranked Black patient, the amount by which they dialed up their efforts was more than 17 times greater than it was when they treated a higher-ranked white patient.

It’s not clear what accounted for this “off-the-charts effort,” the researchers wrote. They speculated that since Black service members were underrepresented among the pool of high-power patients, Black doctors were particularly attuned to their status.

The effects of gender were more difficult to ascertain, since biology dictates that men and women require different kinds of care.

Both male and female doctors invested the most effort in female patients who outranked them. But male doctors upgraded their care for high-power patients of both genders to a much greater extent than female doctors. And unlike female doctors, male doctors devoted more effort to female patients across the board.

Finally, the researchers wondered whether doctors gave preferential treatment to high-power patients because of their elevated status or because those patients had the authority to make trouble if they were unsatisfied with their care. To make inferences about this, they compared the treatment of retirees (who retained their status but had given up their authority) to the treatment of active-duty patients (who still had both).

Schwab and Singh found that high-power patients continued to elicit extra effort from doctors for up to five years after they retired, suggesting that status was an important factor.

“I think it’s really, really cool that even after retirement, you still have these effects,” said Joe C. Magee, a professor of management and organization at the NYU Stern School of Business who studies the role of hierarchy. He sees that as a strong sign that status was driving doctors’ decisions all along.

“What these folks are able to show is that it has real health consequences,” Magee said.

Eric Anicich, a professor of management and organization at the USC Marshall School of Business, called the study “impressive” and the findings “important.”

Although a 3.5% increase or a 1.9% decrease in physician effort may seem small, their cumulative impact is meaningful, especially when it comes to something as critically important as healthcare, he said.

The inequities documented in the study aren’t unique to doctors or to the armed forces, Schwab and Singh said. The mathematical model they developed to describe the behavior in military emergency rooms also helps explain why people in all kinds of situations give preferential treatment to people who look like them: It may help minimize the effects of societal disparities.

In a commentary that accompanies the study, Laura Nimmon of the University of British Columbia’s Centre for Health Education Scholarship wrote that “the ephemeral and unobservable nature of power has made it profoundly difficult to study.” But she said it’s worth the effort to make sure doctors wield their power more fairly.

The disparities reported by Schwab and Singh are “of serious concern to society at large,” she wrote.
