STAR-ADVERTISER State officials said has been detected in three trees at a Maui elementary school campus.
The landscape ohia trees were infected with Ceratocystis huliohia, the less virulent strain of the fungal pathogen, according to the Hawaii Department of Land and Natural Resources.
Crews from DLNR and the Maui Invasive Species Committee on Tuesday removed the trees from the campus, and treated and sealed all cut stumps. Crews also collected all green waste into bags for proper disposal.
Tree materials were burned in a metal container off-site due to the proximity of the elementary school to surrounding homes. DLNR did not say which school campus the trees were on.
MISC also collected samples from nearby ohia trees for follow up monitoring.
Rapid ohia death, which is caused by two fungal species—C. huliohia and C. lukuohia—were first found killing trees on Hawaii island more than 10 years ago. The former may take months to years to kill ohia, while the latter can kill a tree within weeks.

They infect ohia through open bark wounds, and choke off water-transporting vessels, causing leaves to quickly brown out and die.
Rapid ohia death was detected in the summer of 2019 in a lone tree on private property in East Maui.
That tree was also afflicted with C. huliohia. DLNR at the time said it appeared to be an isolated case, and treated it by burning it. In follow up aerial surveys later that year, rapid ohia death was.
Officials said the best way to protect ohia is to avoid injuring the trees, transporting them interisland, which is illegal, and moving ohia wood or vegetation around. People can also clean their hiking boots, gear, tools and vehicles before hiking or entering a wooded area.

FDA approves YolTech's YOLT-101 for familial hypercholesterolemia
YolTech Therapeutics has received the US Food and Drug Administration (FDA) approval for its investigational new drug (IND) application for YOLT-101 to treat heterozygous familial hypercholesterolemia (HeFH). YOLT-101 is an in vivo base editing therapy designed to target proprotein convertase subtilisin/kexin type 9 (PCSK9). Its innovative approach lies in its potential to durably reduce blood low-density lipoprotein cholesterol (LDL-C) levels through a single-dose treatment. The technology behind YOLT-101 incorporates YolTech's adenine base editor, known as hpABE5, which consists of nCas and a new deaminase evolved from Hafnia paralvei. To deliver this therapeutic agent, the company employs an advanced lipid nanoparticle (LNP) delivery system. hpABE5 can perform precise A•T to G•C base conversions without inducing DNA double-strand breaks, thus minimising risks associated with chromosomal abnormalities and off-target effects. YolTech Therapeutics co-founder and CEO Yuxuan Wu stated: 'The FDA IND clearance marks a significant milestone for YolTech. In vivo gene editing represents a new generation of therapeutics — offering one-time, durable solutions for chronic and genetic diseases. 'We are committed to advancing breakthrough gene editing solutions that offer transformative benefits for patients living with severe genetic and cardiovascular diseases.' Currently under evaluation in an ongoing investigator-initiated trial (IIT), YOLT-101 has shown promising results with a favourable safety profile and substantial LDL-C–lowering effects. Familial hypercholesterolemia is a genetic disorder stemming from mutations affecting LDL metabolism-related genes such as LDLR, Apolipoprotein B (APOB) and PCSK9. Individuals suffering from FH typically experience elevated LDL-C levels, which contribute to a heightened risk of developing early-onset atherosclerotic cardiovascular diseases.

Physicists use AI to hunt for UAPs and UFOs
An international team of physicists has developed a new methodology to aid NASA and other government agencies in their ongoing investigations into unidentified aerial phenomena (UAPs). The result is a novel strategy integrating a specially designed artificial intelligence program that was partially inspired by the physicists' own hunt for elusive dark matter. More popularly known as unidentified flying objects or UFOs, UAPs aren't necessarily considered as outlandish as they were decades ago. Setting aside the various theories that point to mysterious visitors from another planet, analysis increasingly centers on determining more worldly explanations. UAPs are often explained by classified experimental aircraft, astronomical events, or simply a case of mistaken drone identity. Meanwhile, a small percentage of sightings continue to baffle experts. Over the last few years, the US government has attempted to present a more transparent approach to its UAP research, while the military continues a campaign to destigmatize reporting sightings among its ranks. In November 2024, Congress held a publicly televised joint subcommittee hearing about UAPs featuring a former US Navy rear admiral and NASA administrator. While not without its fair share of criticism, these and similar events are shifting the overarching narrative around unidentified aerial phenomenon. Researchers like Matthew Syzdagis at the University of Albany have followed this evolving discourse for years. An associate professor of physics focused on dark matter, Syzdagis recently began collaborating with over 30 colleagues around the world to determine if this approach to hunting dark matter could be adapted to the search for UAPs. Their results, published this month in the journal Progress in Aerospace Studies, offer a new interdisciplinary methodology to review the past and future UAP sightings. 'As this process moves forward, it's critical that future study of UAPs follows a rigorous, repeatable method that can be tested and confirmed by other researchers,' Syzdagis said in a statement. 'We aim to establish a roadmap for these efforts with this paper.' The team relied on an array of datasets and tools to build their framework, including publicly available Doppler weather information from the National Weather Service (NWS). The NWS data was used to corroborate observations from additional equipment and determine if any of them simultaneously recorded a given anomaly. They then utilized Cosmic Watch, a radiation-detection system, to assess if a target UAP observed by infrared cameras was accompanied by ionizing radiation. To help analyze the infrared data, Szydagis created a new software program called Custom Target Analysis Protocol (C-TAP) that utilizes machine learning alongside human verification to review individual camera frames on a pixel-by-pixel basis. Inspired by similar strategies used to scan for direct evidence of dark matter, C-TAP then flags and separates actual UAP observations from any digital noise. Finally, these results were overlaid with trigonometric calculations to exclude any known objects in the sky like satellites or the International Space Station. To test it all out, Szydagis and colleagues used their new methodology to review observable light and infrared images collected on a 2021 field expedition around Laguna Beach, California, amid a period of heightened UAP reports. In total, the team reviewed about one hour of triggered visible and night-vision video footage along with over 600 hours of infrared data and 55 hours of background radiation measurements. Of the multiple anomalies initially flagged, researchers were able to offer plausible and likely explanations for all sightings except for one—a collection of bright white dots inside a dark spot recorded across multiple videos. And even then, it seems unlikely that the UAP event was unique. 'At this point, none can be classified as true anomalies, although further study of remaining ambiguities may alter this conclusion,' the study's authors wrote in their conclusion. Moving forward, the team hopes their methodology will help more researchers around the world continue to vet UAP sightings on a scientific, unbiased basis. 'Given the longstanding, global nature of the UAP/UFO question, [and] the air safety and security implications of their presence… studying and understanding these phenomena is of great and urgent importance,' added University of Albany physics professor and study lead author Kevin Knuth.
