Changes to the microbes that live in the gut can identify people at greater risk of Parkinson’s disease long before symptoms develop, according to a new study that also raises hopes for novel therapies.Discovery of a Distinct Gut Microbiome Signature in At‑Risk IndividualsResearchers at University College London led by Prof Anthony Schapira identified a microbial pattern that is more pronounced in individuals carrying a genetic risk for Parkinson’s and even stronger in diagnosed patients. The signature was detectable in a small fraction of the general population, suggesting a pre‑symptomatic risk group.Scale of the Study and Microbial Shifts Quantified271 Parkinson’s patients, 43 genetically predisposed but asymptomatic participants, and 150 healthy controls were initially analysed.Differences were found in 176 gut microbe species (over a quarter of the total surveyed).Follow‑up validation used data from 638 Parkinson’s cases and 319 controls across the UK, South Korea and Turkey.The alterations were independent of medication use and correlated with dietary patterns high in processed foods and saturated fats.Implications for Early Diagnosis and Preventive StrategiesThe microbial signature could enable clinicians to flag high‑risk individuals years before motor symptoms appear, opening a window for interventions such as diet modification or microbiome‑targeted therapies. Alpha‑synuclein production, a protein linked to neuronal damage, may be influenced by gut inflammation driven by specific bacteria.Future Directions: Clinical Trials and Therapeutic ProspectsFurther research is needed to determine causality and to test whether reshaping the gut ecosystem can delay or prevent disease onset. Ongoing clinical trials will explore probiotic, prebiotic, and dietary approaches, while the findings reinforce the growing emphasis on lifestyle factors in Parkinson’s management.

The Breakthrough prize, often referred to as the 'Oscar of science', has been awarded to a team of scientists for their groundbreaking work in gene therapy. Jean Bennett, a molecular biologist, and Albert Maguire, an ophthalmologist, who met while dissecting a brain at Harvard Medical School, have been recognized for their 25-year-long project that led to the development of Luxturna, the first approved gene therapy for blindness.The therapy has transformed the lives of people born with Leber congenital amaurosis (LCA), a genetic disorder that typically causes total blindness by early adulthood. The treatment, which smuggles a working version of the gene into retinal cells, has shown profound improvements in patients, with one patient describing seeing their child's face for the first time.The $3m prize is shared with physician Katherine High, who worked with Bennett and Maguire on the project. The couple's work is a testament to their dedication and perseverance, with Bennett noting that she was 'overwhelmed' by the news and describing it as one of the most 'miraculous eureka moments' she could imagine.Bennett also expressed concerns about the US administration's attacks on science, warning that it could 'cause damage for generations to come' and lead to a brain drain that the country would struggle to recover from.The Breakthrough prizes, founded by Silicon Valley entrepreneurs, recognize outstanding achievements in life sciences, mathematics, and physics. Other prizes awarded included work on a gene therapy for sickle cell anaemia and beta thalassaemia, and the discovery of genetic drivers of frontotemporal dementia and ALS.

President Donald Trump signed an executive order on Saturday in the Oval Office, joined by podcaster Joe Rogan, to fast‑track the federal review of psychedelic drugs such as ibogaine, aiming to broaden treatment options for serious mental illness.The ceremony highlighted Rogan’s long‑standing advocacy for ibogaine, a plant‑derived compound used by some veteran groups to address post‑traumatic stress. Rogan recounted texting Trump about the drug, to which the president replied, “Sounds great. Do you want FDA approval? Let’s do it.”Trump framed the order as a lifeline for patients: “Today’s order will ensure that people suffering from debilitating symptoms might finally have a chance to reclaim their lives and lead a happier life.” He added that successful outcomes could have “a tremendous impact.”In a brief moment of levity, Trump joked, “Can I have some, please? I’ll take some.” He quickly refocused, noting he has no time for depression and stays busy instead.The move enjoys rare bipartisan backing, despite ibogaine and other psychedelics remaining classified under the federal government’s most restrictive drug schedule.Health Secretary Robert F. Kennedy Jr. had previously pledged to ease medical access to psychedelics, a stance echoed in the new order, which directs the Department of Health and Human Services to allocate at least $50 million to states developing programs for serious mental‑health conditions.Simultaneously, the FDA is set to issue “national priority” vouchers for three psychedelic candidates. Commissioner Marty Makary said the vouchers will enable rapid approval “if they align with our national priorities.”The agency also plans the first human trials of ibogaine in the United States, overcoming earlier concerns about potential fatal heart effects.Ibogaine’s origins trace back to the Bwiti religious ceremonies in West‑Central Africa, where the plant has been used for centuries in spiritual contexts.Former Navy SEAL Marcus Luttrell, also present at the event, praised ibogaine, stating, “It absolutely changed my life for the better.”Rogan’s endorsement and the executive order have added a new dimension to Trump’s 2024 campaign narrative, even as he has publicly questioned the administration’s stance on the war with Iran.

Al-Noor Centre has become a vital source of hope for blind children living in the besieged Gaza Strip. In a region where basic infrastructure is strained, the centre offers specialized education, mobility training, and psychosocial assistance that enable young patients to navigate daily challenges. By delivering tailored services, the centre not only addresses the immediate needs of its beneficiaries but also underscores the broader importance of disability‑focused humanitarian aid in conflict zones. Such initiatives help mitigate long‑term social exclusion and foster greater community resilience. Stakeholders and donors recognize that supporting facilities like Al-Noor is essential for safeguarding the rights of children with disabilities, especially amid ongoing security and economic pressures. The centre’s work illustrates how targeted interventions can serve as a lifeline, offering both practical assistance and a sense of dignity to a vulnerable population. As Gaza continues to grapple with humanitarian challenges, the sustained operation of the Al-Noor centre stands as a testament to the impact of focused aid programs that prioritize the most marginalized groups.

Thousands of Iranians who had fled Tehran during the recent war have begun returning to their homes or workplaces, despite the fragile truce and looming anxiety over the approaching ceasefire deadline.Mehdi, a 36-year-old IT professional, is one of them. He had fled to the north with relatives in the early days of the war, but has now returned to find his home damaged by blasts, with shattered glass and blown-out bedroom window frames.The city is riddled with ruined buildings, destroyed infrastructure, and an economy in turmoil. Mehdi describes the experience of hearing missiles hit nearby: 'There's a whistling sound I hope you never hear … a missile so close that you don't know if it's going to hit your house or your neighbour's.'Many residents, especially those reliant on the internet, have lost their livelihoods due to the 45-day internet blackout imposed by Iranian authorities. This has left most of Iran's population cut off from the world, with some paying large sums to access the internet through Starlink and VPNs.Noor, an activist based in Tehran, says 10 million Iranians depend on internet access to run small businesses or make an income. The economic pressure has become unbearable, with food items and medications for patients with serious or chronic illnesses becoming difficult to find or afford.The economic crisis has worsened, with factories struggling to operate due to a lack of raw materials, construction workers losing jobs, and workplaces laying off staff or reducing their workforce.

Israel has escalated its attacks on medical workers in Lebanon, with a recent 'quadruple tap' killing four medics and wounding six others. The attacks, which have been condemned by the Lebanese health ministry and the World Health Organization, have left healthcare workers in Lebanon feeling vulnerable and under attack.The 'quadruple tap' occurred when Israeli forces targeted an initial airstrike site, then hit the ambulances and medical workers who responded to the scene, and finally struck again twice more. This tactic has been criticized as a blatant violation of international humanitarian law, which protects medical workers and facilities.The Lebanese health ministry has accused Israel of deliberately targeting ambulance crews, stating that 'paramedics have become direct targets, pursued relentlessly in a blatant violation that confirms a total disregard for all norms and principles established by international humanitarian law.'The attacks have resulted in the deaths of 91 healthcare workers and the wounding of 214 others in Lebanon since the Israel-Hezbollah war started on March 2. The World Health Organization has called for the immediate protection of healthcare facilities, health workers, ambulances, and patients.The Israeli military has not provided justification for its repeated attacks on medical infrastructure and workers, apart from accusing Hezbollah of using ambulances and hospitals to transport fighters and weapons, without providing evidence for the claim.

Aaron Pierre delivers a storming, almost hypnotic performance as Randle P. McMurphy, instantly igniting the stale atmosphere of a 1960s American psychiatric ward. His swagger‑filled stride and sudden, childlike scampers create a compelling contrast that keeps the audience on edge.From the opening moments, McMurphy clashes with the authoritarian Nurse Ratched (Olivia Williams), provoking the other patients to rebel, play, and celebrate life beyond the ward’s walls. Pierre’s physicality—alternating between boisterous hugs and a frantic, vulnerable laugh—captures the character’s chaotic charisma.Director Clint Dyer, fresh from his acclaimed 2022 Othello, reshapes the narrative by casting the inmates almost entirely with Black actors. This choice injects a fresh political dimension, turning the patients into “pawns in a system designed to disempower.” Each time Ratched addresses them as “boys,” the line feels like an implicit sneer.While the script does not overtly discuss race—apart from Chief Bromden’s (Arthur Boan) Indigenous background—the production foregrounds the systemic misogyny embedded in both the novel and the 1963 Dale Wasserman adaptation. McMurphy’s mantra, “I fight and fuck,” teeters between liberated individualism and a problematic reclamation of alpha‑male tropes.Olivia Williams, who stepped into the role of Nurse Ratched late in rehearsals, gives the character a “ramrod spine and starched smile.” Her performance underscores the unchecked cruelty of a regime where the doctor (Matthew Steer) is a peripheral, snickering figure, leaving Ratched’s authority unchecked and increasingly vicious.Ken Kesey’s own experience as a government‑run LSD guinea‑pig informs the play’s visceral critique of psychiatry. The production’s lighting, designed by Chris Davey, erupts in scarlet and blue hues that echo the anti‑psychiatry movement of the 1960s, while the depiction of medication, group therapy, and electroconvulsive therapy feels deliberately brutal.Staged in the round at the Old Vic, the audience becomes a “ring of often appalled observers.” Ben Stone’s set design, with its white and pond‑green tiles beneath a soaring ceiling, creates a claustrophobic floor that simultaneously aspires upward—mirroring the characters’ yearning for freedom.The ensemble, led by Giles Terera’s refined Dale Harding, adds subtle layers of tension through nuanced tics and gestures. Dyer bookends the show with a reference to Congo Square in New Orleans, a historic site of Black and Indigenous resistance, framing the play’s cruelty through a lens of cultural resilience—though the production remains largely filtered through a male gaze.The production runs at the Old Vic until 23 May 2026, offering London audiences a bold, politically charged reinterpretation of a classic American drama.

A recent Cochrane review analyzing 17 clinical trials involving over 20,000 people with mild cognitive impairment or dementia has concluded that anti-amyloid drugs have a 'trivial' effect on cognition and dementia severity over 18 months.The review, which assessed seven anti-amyloid drugs, found that improvements in functional ability were 'small at best' and that the drugs caused more swelling and bleeding in the brain than the placebo.The findings are a blow to the new wave of drugs designed to slow Alzheimer's by clearing clumps of amyloid protein that build up in the brain. Despite initial hype, with some regulators approving drugs like lcanemab and donanemab, many countries have stopped short of providing them through public health services due to concerns over their effectiveness and cost.Critics of the review argue that it combines results from older, failed drugs with those from newer, more effective medicines, which may skew the conclusions. However, the review's authors defend their approach, stating that all the drugs aimed to remove amyloid from the brain and assessed the impact on patients in a similar way.The review's lead author, Edo Richard, notes that the effect sizes are too small for patients and caregivers to notice, and that the drugs are also 'burdensome' due to the need for regular intravenous drug infusions and MRI scans.Experts in the field, such as Robert Howard, express concerns that the drugs may not truly alter the course of Alzheimer's, and that it's unfair to raise expectations in patients. Meanwhile, Alzheimer's Research UK argues that the review's conclusions are limited by its methodology and that anti-amyloid treatments will not be the whole answer to curing Alzheimer's.

Argentina’s justice system has reopened the case surrounding the death of football icon Diego Maradona, with prosecutors branding his medical team as “a bunch of amateurs” who missed a critical window to save him.The trial of seven healthcare professionals—doctors, psychologists and nurses—resumed on Tuesday in San Isidro, a suburb of Buenos Aires, after the original proceedings were annulled when a presiding judge was found to have participated in a documentary about the case.Maradona, who died in November 2020 at age 60 while recuperating from surgery for a brain clot, is alleged to have suffered from heart failure and acute pulmonary edema two weeks post‑operation. Prosecutor Patricio Ferrari asserted that the patient began to deteriorate 12 hours before his official death and that a timely transfer to a clinic could have prevented the fatal outcome.According to the indictment, the defendants’ decision to keep Maradona at home rather than in a hospital, coupled with a series of “omissions” described as “cruel,” constitutes homicide with possible intent. If convicted, each could face prison terms ranging from eight to 25 years.The new proceedings, expected to conclude by July at the earliest, will hear testimony from roughly 120 witnesses. Among the accused, former team doctor Leopoldo Luque and other staff members will be scrutinized for their role in the athlete’s care.Maradona’s family—daughters Dalma, Gianinna and Jana, and former partner Veronica Ojeda—attended the hearing, urging the courts to deliver “justice for Diego” and allow the legend to “rest in peace.” Outside, about 50 supporters waved Argentine flags and signs demanding accountability for the beloved “D10s.”Defense counsel Vadim Mischanchuk argued that the former star’s death resulted from a “progressive decline in his health” rather than medical malpractice, emphasizing that the condition was natural and unavoidable.Legal analyst Fernando Burlando, representing the Maradona family, highlighted the absence of a stethoscope on the legend’s chest during the critical two‑week period, using the instrument as a stark symbol of alleged negligence.The case revives national grief that first erupted when Maradona’s body lay in state at the presidential palace, drawing tens of thousands of mourners amid the COVID‑19 pandemic.
