Watch: 1,000-Foot Lava Jets Erupt From Hawaii's Kīlauea Volcano
The infamous crater has been spurting fountains of lava on and off since the end of last year, and on May 25, it shot a fiery jet of molten rock over 300 meters (1,000 feet) into the sky.
The United States Geological Survey (USGS) livestreamed a video of the uncontrolled outburst – the volcano's 23rd tantrum since December 2024, and the biggest of the bunch.
All in all, Kīlauea's latest blowup lasted for just over six hours. Beginning at 4:15 pm Hawaii-Aleutian Standard Time, thin jets of lava began erupting from the north vent, turning from sporadic bursts to sustained fountains of lava.
Within half an hour, the situation at the north vent had escalated quickly, and a lava fountain reached its pinnacle of 300 meters.
Soon after, in a south vent, other fountains of lava reached 250 meters in height.
"Large lava flows erupted from both vents and covered about half of Halema'uma'u crater floor," reads a USGS update.
By 10:25 pm that night, both vents had calmed down.
Luckily, for now, all of the eruptions have been contained within Hawaiʻi Volcanoes National Park on the island of Hawai'i. But that doesn't mean surrounding populations won't face fallout.
The eruptive plume of ash, volcanic glass, and rock produced by Kīlauea on May 25 reached at least 1,500 meters into the sky.
Scientists at the USGS say their primary concern is the volcanic gas, which could travel downwind and impact human health, possibly causing respiratory issues if concentrations in the air are high enough.
Eruptions like these, however, can also produce strands of volcanic glass, called Pele's hair, which can also travel on the wind and cause skin and eye irritation.
The volcano has quietened down for now, but in its current phase it seems to be kicking up a fuss every week or so.
There's no signs a larger eruption is growing, but another outburst of lava is likely on the horizon.

Genentech and Roche Present New Insights in Alzheimer's Disease Research Across Its Diagnostics and Pharmaceutical Portfolios at AAIC
– Trontinemab's Phase Ib/IIa Brainshuttle™ AD study continues to show rapid and robust clearance of amyloid plaques, with 91% becoming amyloid PET negative and ARIA-E remaining <5% – – Design of the Phase III TRONTIER 1 and 2 studies of trontinemab in early symptomatic Alzheimer's disease featured, with initiation planned in 2025 – – Plans for new Phase III trial investigating trontinemab in preclinical Alzheimer's disease, in people at high risk of cognitive decline – – New real-world data support Elecsys pTau217 as a standalone blood test, comparable to a PET scan, for rule-in and rule-out identification of amyloid pathology – SOUTH SAN FRANCISCO, Calif., July 28, 2025--(BUSINESS WIRE)--Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY) announced today that new data from its Alzheimer's development portfolio is being presented at the Alzheimer's Association International Conference (AAIC) in Toronto, Canada (July 27-30). These data exemplify the comprehensive approach Roche is taking in addressing Alzheimer's across the entire patient journey. Featured oral presentations include the latest results from the ongoing Phase Ib/IIa Brainshuttle™ AD study, which continue to support rapid and robust reduction of amyloid plaques, and design of the Phase III TRONTIER 1 and 2 studies of investigational trontinemab for early symptomatic Alzheimer's disease, with initiation planned later this year. As part of its growing Alzheimer's development program, Roche announced today its plans for an additional Phase III trial to investigate trontinemab in preclinical Alzheimer's disease. The trial will focus on individuals at risk of cognitive decline, with the goal of potentially delaying or preventing the progression of the disease to symptomatic stages. "Alzheimer's disease represents one of the greatest challenges in healthcare today and tackling it requires early detection and effective therapeutics," said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. "Trontinemab is designed to target a key driver of Alzheimer's disease biology more effectively in the brain. Combining new treatment avenues with advanced diagnostics may enable earlier and potentially more effective intervention. With plans for Phase III trials in both early symptomatic and preclinical Alzheimer's disease, we are advancing science with the goal of delaying—and ultimately preventing—progression of this devastating condition." Late-breaking oral and poster presentations highlight the potential of Roche's Elecsys® pTau217 as a reliable and accessible blood-based biomarker test, providing comparable results to PET scan and cerebrospinal fluid (CSF) diagnostics for rule-in and rule-out diagnosis of amyloid pathology, a hallmark of Alzheimer's disease, across care settings. The test, which received Breakthrough Device Designation from the U.S. Food and Drug Administration last year, will also be utilized in Roche's TRONTIER studies. "Blood based testing for Alzheimer's disease has the potential to greatly improve patient access and decrease the time to definitive disease diagnosis," said Matt Sause, CEO of Roche Diagnostics. "Our data show that the Elecsys pTau217 test performs comparably to PET scans but can be performed with a simple blood draw and analyzed in a routine clinical laboratory. This has the potential to transform the diagnosis of Alzheimer's and provide clear answers to caregivers, patients, and their families." Up to 75% of people living with symptoms of Alzheimer's disease globally have not been diagnosed, and those who have, waited an average of 2.8 years, and even less have received any form of treatment. Diagnostics play a crucial role in addressing the global challenge of Alzheimer's, not only to detect and identify people with the disease early, even before the first symptoms, but also to rule out those who may or may not benefit from specific treatments. Pharmaceuticals In a 90-minute Featured Research session, designs were shared for the Phase III studies, TRONTIER 1 and 2, which will initiate later this year, investigating the efficacy and safety of investigational trontinemab in people with early Alzheimer's disease. The primary endpoint will measure the change in cognition and function based on the Clinical Dementia Rating – Sum of Boxes scale after 18 months of treatment. Secondary endpoints will include assessments of cognition, function, behavioral symptoms, and quality of life. A pre-screening study, TRAVELLER, based on a brief clinical assessment and a plasma biomarker, which will be identified using the Elecsys pTau217 test, has also been initiated, to enable broader community outreach and extend access to these trials to more diverse populations representative of Alzheimer's disease. New data on the latest results for trontinemab from the completed dose-expansion part of the 1.8 mg/kg and 3.6 mg/kg cohorts from the ongoing Phase Ib/IIa Brainshuttle AD study continued to show rapid and robust reduction of amyloid plaques in the brain as measured by amyloid positron emission tomography (PET). In the 3.6 mg/kg cohort, trontinemab reduced amyloid levels below the 24 centiloid positivity threshold in 91% of participants (n=49/54) after 28 weeks of treatment; 72% (n=39/54) achieved deep clearance below 11 centiloids. These data were reinforced by early and significant reductions in fluid biomarkers of Alzheimer's disease, including total tau, phosphorylated Tau (pTau)181, pTau217, and neurogranin measured in CSF and continues to show a favourable safety and tolerability profile. Amyloid-related imaging abnormalities-edema/effusion (ARIA-E) continued to be observed in <5% of participants (blinded data; N=4/149 across 1.8 and 3.6 mg/kg dose cohorts). All cases were radiographically mild, one was associated with mild and transient symptoms. Diagnostics Roche will present data on a new study comparing the pTau217/Ab42 plasma ratio to the high-throughput, fully automated Elecsys pTau217 assay. The presentation will report on the accuracy of these tools in detecting amyloid pathology. Together with the high throughput and full automation of the assay, these data will assess the potential of Elecsys pTau217 as an accurate standalone rule-in and rule-out test that could be scaled up for broad implementation in routine clinical practice worldwide. Additionally, results from a cohort-based model of healthcare utilization in the U.S. demonstrated that using the Elecsys® pTau181 blood-based rule-out test in primary care scenarios improved diagnostic accuracy and reduced resource use compared with the current standard-of-care clinical, cognitive and imaging tests. If made available in primary care settings, the Roche Elecsys® pTau181 blood test has the potential to reliably avoid the need for further confirmatory testing in nearly all people who receive a negative result. This will avoid the need for these people to undergo unnecessary testing using CSF or PET, which often come with long wait times and high cost, resulting in further delays to diagnosis and cost to healthcare systems.

Trontinemab is designed for the efficient transport across the blood-brain barrier to target aggregated forms of amyloid beta and remove amyloid plaques in the brain. The uniqueness of trontinemab is based on Roche's proprietary Brainshuttle technology combining an amyloid beta-binding antibody with a transferring receptor (TfR1) shuttle module. As a result, high central nervous system (CNS) exposure of trontinemab may be achieved at low doses, leading to a rapid and deep amyloid clearance. Due to its unique properties, trontinemab might unlock the full potential of disease-modifying monoclonal antibodies by effectively penetrating the brain and potentially leading to slowing of disease progression. About Roche in Alzheimer's Disease With more than two decades of scientific research in Alzheimer's disease, Roche is working towards a day when we can detect and treat the disease early, in order to slow down, stop or even prevent its progression to preserve what makes people who they are. Today, the company's Alzheimer's disease portfolio spans investigational medicines for different targets, types and stages of the disease, including trontinemab. On the diagnostics side, it also includes approved and investigational tools, including digital and blood-based tests and CSF assays, aiming to more effectively detect, diagnose and monitor the disease. Yet the global challenges of Alzheimer's disease go well beyond the capabilities of science, and making a meaningful impact requires collaboration both within the Alzheimer's community and outside of healthcare.

More Data Cement COVID's Impact on Patients With Cancer
TOPLINE: New data confirm the impact COVID infection can have on patients with cancer and identified several risk factors associated with hospitalization and death. Receipt of chemotherapy as well as a baseline history of stroke, atrial fibrillation, or pulmonary embolism were each associated with nearly double the risk for COVID-related hospitalization. Prior vaccination halved this risk. Older age and earlier hospitalization were associated with a greater risk for death. METHODOLOGY: Patients undergoing active cancer treatment are at increased risk for severe COVID-19 due to immunosuppression, but risk factors for hospitalization and death are not well-defined. Researchers conducted a prospective cohort study involving 1572 patients with cancer (median age, 60 years; 53.4% women), enrolled within 14 days of a positive SARS-CoV-2 test; participants had received active treatment for cancer within 6 weeks before testing or had undergone prior stem cell transplant or CAR T-cell therapy. Patient screening and enrollment took place between May 2020 and February 2022. Treatments included chemotherapy (34.3%), targeted therapy (27.7%), and immunotherapy (10.6%). Breast (23.6%) and lung (13.9%) cancers were the most common cancer types. Overall, 64% of participants had metastatic disease, and at enrollment, 64% had not received a COVID vaccine. Study outcomes were COVID-related hospitalization or death. Risk factors for hospitalization and for death among hospitalized patients were evaluated separately. TAKEAWAY: At 90 days after an initial positive test, COVID-related mortality was 3% and remained stable at subsequent follow-ups. The highest incidence occurred in patients with lymphoma, followed by those with acute leukemia or lung cancer; the lowest incidence occurred in those with other types of solid tumors and blood cancers. Hospitalization for COVID-19 occurred in 18.4% of patients within 90 days of enrollment. The risk for hospitalization was elevated among patients who received chemotherapy (hazard ratio [HR], 1.97) and those with a history of stroke, atrial fibrillation, and pulmonary embolism (HR, 1.78). Vaccination prior to infection reduced the risk for hospitalization by nearly half (HR, 0.52). Hospitalization for COVID-19 within 30 days of infection was associated with an increased risk for death (HR, 14.6). Among patients hospitalized for COVID within 30 days, age 65 years or older was the only significant predictor of COVID-specific death (HR, 3.49). Over the 2-year follow-up, there were 1739 disruptions to cancer treatment; 50.7% of these were attributed to COVID-19, and most occurred within 30 days of a positive test. IN PRACTICE: 'The data from this prospective cohort study confirm and expand previous retrospective case series that have found factors, including hematologic cancers, chemotherapy receipt, and lung cancer, as associated with COVID-19 severity,' the authors of the study wrote, noting that the results 'showed that COVID-19 had a significant impact on patients with cancer, including hospitalization, treatment disruptions, and death.' SOURCE: This study, led by Brian I. Rini, MD, Vanderbilt-Ingram Cancer Center, Nashville, Tennessee, was published online in JAMA Oncology. LIMITATIONS: Information on specific strains was not available. This study lacked a control group of patients without COVID-19, which limited causal inference. Additionally, as participants were enrolled through the National Cancer Institute trial networks, generalizability to a broader population could be limited. DISCLOSURES: This study was funded in part by the Coronavirus Aid, Relief, and Economic Security Act and the National Cancer Institute National Clinical Trials Network, Experimental Therapeutics Clinical Trials Network, and Community Oncology Research Program grants via the U10 funding mechanism. Several authors declared receiving grants and/or personal fees and having other ties with various sources.

Foul-smelling corpse flower reaches peak bloom as crowds line up in Massachusetts
An extremely rare and foul-smelling flower has reached its peak bloom Sunday night in Dover, Massachusetts. The amorphophallus titanum, or corpse flower, only blooms once every 10 years for a 24-hour period. The flower, named Eliza, can currently be seen at the Massachusetts Horticultural Society in Dover. Experts said the flower grows from a seed, one big tall leaf per year, for about 10 years. Then it literally heats up, creating a gas inside, and then opens. The Massachusetts Horticultural Society was open Sunday night until midnight for people who came to see and smell the flower. "I came because it's a rare event and I always thought it'd be neat to see one of these rare flowers," said visitor Shari Wall. "The smell is not easy to take, it's kind of like a hot garbage can!" "It smells like rotting diapers. Though I hear when it gets hotter, it's more stinkier, so I'm glad I'm here when it's cooler," said visitor Isaac Verardo. Wheaton College grew the corpse flower in their research greenhouse in nearby Norton. In the middle of summer, no one would be on-campus to experience it, so the Massachusetts Horticultural Society agreed to host the event. Anyone interested in braving the flower's rancid smell can visit the Massachusetts Horticultural Society starting Monday at 8 a.m. until 6 p.m. Timed tickets are required to view the flower and can be purchased on their website.
