Excess Deaths Attributable to the Los Angeles Wildfires

While there were only 30 direct fatalities from the Los Angeles wildfires, this study estimates that 440 deaths from January 5 to February 1, 2025, were attributable to the wildfires. These additional deaths likely reflect a combination of factors, including increased exposure to poor air quality and health care delays and interruptions.

JAMA Increases in Suicides and Overdoses During the 2023 Wildfires in Maui

The results of this study show that the 2023 Maui wildfires had immediate effects on suicide and overdose deaths in Maui and across the Hawaiian Islands broadly. The latter finding suggests that direct exposure to the wildfires may have increased risk of suicide and overdose death among Maui residents who migrated to neighboring islands during or after the fires.

JAMA Network Open Health and Social Support in the Aftermath of the Maui Wildfires

In this cohort study of adults affected by the Maui wildfires, substantial midterm cardiopulmonary and psychological health burdens were observed. Higher social support was associated with improved mental health outcomes but did not appear to buffer physiological outcomes such as reduced lung function. These findings highlight the need for disaster response models that integrate clinical surveillance, targeted mental health interventions, and culturally anchored community-based support. As climate-driven disasters intensify, proactive strategies to monitor and mitigate their long-term health effects will be essential to protect vulnerable populations and enhance resilience.

Replacing brain immune cells in mice slows neurodegeneration in Stanford Medicine study

2025-08-06

Tay-Sachs and Sandhoff diseases, genetic disorders affecting the brain, have no effective treatment and are typically fatal within the first years of life. Scientists have reasoned that replacing the affected cells with those that are genetically healthy could slow or halt the neural degeneration that causes the symptoms. But the approach has been plagued with problems, including poor engraftment in the brain and a graft-versus-host response in which transplanted cells attack healthy tissue. Now researchers at Stanford Medicine have developed a way to replace more than half of the most severely affected cells, called microglia, with ...

Early heartbeats direct the heart’s own development and growth

Francis Crick Institute press release Under strict embargo: 16:00hrs BST Wednesday 6 August 2025 Peer reviewed Experimental study Animals (zebrafish) Early heartbeats direct the heart’s own development and growth Researchers at the Francis Crick Institute have discovered that the heart’s own contractions trigger biological signals that guide the formation of a functional beating heart. Their study in zebrafish highlights the heart’s ability to remodel and adapt to physiological demands and could also reveal what goes wrong during congenital ...

Changes to El Niño occurrence causing widespread tropical insect and spider declines

2025-08-06

Arthropods, including insects and spiders, make up the vast majority of animal species on the planet. Despite their small size they are irreplaceable contributors to the health of natural habitats, as well as vital food sources for birds and other larger animals. But, arthropods may be declining globally. There is some evidence to support reduced numbers of species in temperate regions of the Northen Hemisphere. In the tropics, however, evidence for arthropod declines has so far been limited. A recent international collaboration of scientists has attempted to find this missing evidence, with the findings published in Nature. The ...

Nanophotonics: An ultrafast light switch

2025-08-06

In nanophotonics, tiny structures are used to control light at the nanoscale and render it useful for technological applications. A key element here is optical resonators, which trap and amplify light of a certain color (wavelength). Previous methods of controlling these resonances were more like a dimmer switch: You could weaken the resonance or slightly shift its color. However, genuine on-and-off switching was not possible, as the resonators always remain fundamentally coupled with the light. A team led by Andreas Tittl, Professor of Experimental Physics at LMU, has now achieved precisely this breakthrough together with partners from Monash ...

Human instruction with artificial intelligence guidance provided best results in neurosurgical training

2025-08-06

Artificial intelligence (AI) is becoming a powerful new tool in training and education, including in the field of neurosurgery. Yet a new study suggests that AI tutoring provides better results when paired with human instruction. Researchers at the Neurosurgical Simulation and Artificial Intelligence Learning Centre at The Neuro (Montreal Neurological Institute-Hospital) of McGill University are studying how AI and virtual reality (VR) can improve the training and performance of brain surgeons. They simulate brain surgeries using VR, monitor ...

Archaeologists find oldest evidence of humans on ‘Hobbit’s’ island neighbor – who they were remains a mystery

2025-08-06

Recent findings, made by Griffith University researchers, show that early hominins made a major deep-sea crossing to reach the Indonesian island of Sulawesi much earlier than previously established, based on the discovery of stone tools dating to at least 1.04 million years ago at the Early Pleistocene (or ‘Ice Age’) site of Calio. Budianto Hakim from the National Research and Innovation Agency of Indonesia (BRIN) and Professor Adam Brumm from the Australian Research Centre for Human Evolution at Griffith University led the ...

Novel microwave dielectric ceramics enable high-performance 5G/6G communication devices

2025-08-06

With the global rollout of 5G networks and the onset of 6G research, the need for advanced materials that enable faster and more reliable wireless communication has never been greater. Microwave dielectric ceramics, key components in devices like resonators, filters, and antennas, must meet strict criteria: low signal delay, low loss, and stable performance across temperatures. A research team from Guilin University of Technology in China has risen to this challenge by developing a novel garnet-type ceramic, YMAG. Synthesized using a solid-state reaction method, YMAG exhibits impressive microwave properties: a permittivity (εr) of 9.86, a quality factor ...

Revealed: New vaccine target to block malaria transmission

2025-08-06

Australian researchers have visualised a key protein complex in malaria parasites for the first time, uncovering a new target for next-generation vaccines that could help stop the disease from spreading. Using cutting-edge cryo-electron microscopy, the research team from WEHI captured the first detailed structure of a protein complex essential for malaria parasite fertilisation. The discovery published in Science has led to the development of a promising new mRNA vaccine candidate that stops the malaria parasite from reproducing inside mosquitoes, breaking the cycle of transmission ...

Air purifiers may reduce heart risks for people exposed to traffic pollution

2025-08-06

WASHINGTON (August 6, 2025) — Using portable high-efficiency particulate air (HEPA) purifiers at home can significantly lower systolic blood pressure (SBP) in adults with elevated baseline readings — even in areas with relatively low overall air pollution levels, according to a study published today in JACC, the flagship journal of the American College of Cardiology. Particulate matter (PM) is a major contributor to air pollution and is strongly associated with cardiovascular disease (CVD). People ...
