Standing dead trees in Yellowstone National Park are growing wildfire hazards, especially near park infrastructure. A new study published in Forest Ecosystems explores how these dead trees contribute to fire risk and threaten roads, buildings, and trails. Dead trees, particularly those that remain standing, are a significant fire hazard. These trees—often caused by pests, diseases, and climate change—create a large amount of dry, combustible material. As temperatures rise and droughts intensify, the risk of wildfires increases, making it essential to understand how dead trees contribute to fire danger. The team used a random forest classification model, a powerful ...

The widely used nickel-based superalloys for turbine engine materials showed a limited-service temperature of only 1200℃, and did not exceed 1500℃ even when coated with thermal barrier coatings, which is urgent to develop the advanced thermal protection system for turbine engines with higher thrust-weight ratios. Niobium alloy coated with silicide coating is undoubtedly considered the most efficient method to reach long-term service, since it can form a dense SiO2 layer with self-healing ability at high temperatures. However, the single silicide coating has a strong tendency to crack vertically ...

The Centers for Disease Control and Prevention (CDC) has selected University of California San Diego as one of three partner institutions to establish a groundbreaking pandemic preparedness initiative, the Community and Household Acute Respiratory Illness Monitoring (CHARM) Network. The new five-year cooperative agreement will help generate information on how respiratory viruses spread and provide insights into factors impacting susceptibility to respiratory illnesses.

The core message of the article is that researchers have developed an innovative technology in plasma spraying-physical vapor deposition known as alternating vapor/liquid phase deposition. By adjusting the arc current, researchers can finely control the evaporation and deposition of SiO2, and through a heat treatment process, achieve in-situ reactions that optimize the composition, structure, and nanoscale dimensions of the coating, creating an orderly arranged multi-layered teak-like biomimetic structure within it. They have conducted an in-depth analysis of the complex deposition mechanisms involved in this process. This new teak-like biomimetic structure coating is expected ...

Researchers have found a low-power, inexpensive way for large numbers of devices, such as machines in factories and equipment in labs, to share information by efficiently using signals at untapped high frequencies. The technology could immediately enable low-cost, efficient real-time monitoring in industrial settings, such as tracking the condition of manufacturing robots or detecting gas leaks in refineries, by eliminating the need for power-hungry signal transmitters. The researchers said that with some engineering improvements, the technology ...

SPOKANE, Wash.—Elderberry juice may be a potent tool for weight management and enhancing metabolic health, according to a recent Washington State University-led study. A clinical trial published in the journal Nutrients found that drinking 12 ounces of elderberry juice daily for a week causes positive changes in the gut microbiome and improves glucose tolerance and fat oxidation. Elderberry, a small dark purple berry found on elder trees native to Europe, is commonly used as a medicinal plant and supplement to promote immune function. Its other potential health benefits are poorly understood, however. “Elderberry ...

Influential inventions often combine existing tools in new ways. The iPhone, for instance, amalgamated the telephone, web browser and camera, among many other devices. The same is now possible in gene editing. Rather than employ separate tools for editing genes and regulating their expression, these distinct goals can now be combined into a single tool that can simultaneously and independently address different genetic diseases in the same cell. Merging Gene Editing and Regulation In a new paper in Nature ...

Researchers in Japan have found that the taller the Japanese black pine trees (Pinus thunbergii) along the coast, the deeper their roots go into the ground. Trees with deeper roots are more resistant to damage from tsunamis and strong winds. Their findings suggest that the resilience of coastal P. thunbergii trees may be improved by inducing deep root growth, specifically in short trees. The study was published in the Journal of Forest Research. Many P. thunbergii trees have been planted in coastal forests in Japan because they are salt-tolerant and can grow in sandy soils lacking nutrients. P. thunbergii ...

Why have males been overrepresented among geniuses in STEM fields so far? A popular biological psychological explanation is the Extreme Male Brain Theory (EMB), which suggests that an overdose of prenatal androgen (male hormone) leads to the hyper-masculine brain type, characterized by a strong geek tendency and insensitivity to others' feelings. This theory explains the etiology of autism spectrum disorder (ASD) and inevitably connects prenatal androgen action with talents in specific fields. However, the current research shows evidence that the opposite story might be true: reduced androgen exposure in ...

Declining blood levels of two molecules that occur naturally in the body track closely with worsening Alzheimer’s disease, particularly in women. Levels were found to drop gradually, from women with no signs of memory, disorientation, and slowed thinking to those with early signs of mild cognitive impairment. Decreases were more prominent in women with moderate or severe stages of the disease. Declines in men were evident in only one molecule, revealing a disease-specific difference between the sexes. Six million Americans, most over the age of 65 and predominantly women, are currently ...

New international research collaboration to develop and test an improved dietary supplement for pregnant women Poor nutrition during pregnancy can have serious consequences for both maternal and child health. A new research collaboration – ‘Mother’s Micronutrient Supplement for Pregnancy and Lactation’ (MoMS) – between researchers in Kenya, Norway and Denmark aims to develop and test a new, improved dietary supplement to reduce incidences of low birth weight, improve maternal and child health, and enhance growth and cognitive development in children. MoMS ...

Continuing significant advancements in the field of xenotransplantation, surgeon-scientists from the University of Maryland School of Medicine provided an extensive analysis on the second patient in the world to receive a genetically-modified pig organ. Lawrence Faucette, 58, received a pig heart at the University of Maryland Medical Center in 2023 to treat his end-stage heart failure. He lived for 40 days before choosing to forgo additional treatment after the transplant began to fail due to rejection. The report documenting insights ...

A Cranfield University, UK, academic has used drone mapping to investigate a 3000-year-old ‘mega fortress’ in the Caucasus mountains. Dr Nathaniel Erb-Satullo, Senior Lecturer in Architectural Science at Cranfield Forensic Institute, has been researching the site since 2018 with Dimitri Jachvliani, his co-director from the Georgian National Museum, revealing details that re-shape our understanding of the site and contribute to a global reassessment of ancient settlement growth and urbanism. Fortress settlements in the South Caucasus appeared between 1500-500 BCE, and represent an ...

During IVF treatment, doctors use ultrasound scans to monitor the size of follicles - small sacs in the ovaries containing eggs - to decide when to give a hormone injection known as the ‘trigger’ to prepare the eggs for collection and ensure that they are ready to be fertilised with sperm to create embryos. The timing of the trigger is a key decision, as it works less effectively if the follicles are too small or too large at the time of administration. After the eggs are collected and fertilised by sperm, an embryo is then selected and implanted into the womb to hopefully lead to pregnancy. Researchers used ‘Explainable ...

Tokyo, Japan – Glass might seem to be an ordinary material we encounter every day, but the physics at play inside are actually quite complex and still not completely understood by scientists. Some panes of glass, such as the stained-glass windows in many Medieval buildings, have remained rigid for centuries, as their constituent molecules are perpetually frozen in a state of disorder. Similarly, supercooled liquids are not quite solid, in the sense that their fundamental particles do not stick to a lattice ...

Toronto, ON – New challenges in HIV prevention and care are emerging due to climate change, according to a review published earlier this month in Current Opinions in Infectious Disease. Researchers from the University of Toronto analyzed 22 recent studies exploring HIV-related outcomes in the context of climate change and identified several links between extreme weather events and HIV prevention and care. Climate change-related extreme weather events, such as drought and flooding, were associated with poorer HIV prevention outcomes, including ...

AMR is when microorganisms that cause infections, such as bacteria and viruses, change over time and no longer respond to antibiotic medicines.  It makes serious conditions such as HIV, tuberculosis and malaria more difficult to treat and increases the risk of severe illness, disease spread and death.  AMR particularly impacts low-to-middle-income countries where water quality is often poor and the spread environmental spread of AMR via wastes can be high.  In 2015 the World Health Organization (WHO) formulated a Global Action Plan to co-ordinate efforts to tackle AMR.  As a result, 194 WHO member states committed to developing country-specific ...

Grapefruit and pummelo contain compounds called furanocoumarins that may affect the blood levels of more than 100 prescription drugs, so that people taking these medications are advised to remove these fruits from their diets. Research published in New Phytologist reveals genetic information about the synthesis of furanocoumarins in different citrus plant tissues and species and provides new insights that could be used to develop grapefruit and pummelo that lack furanocoumarins. The research indicates that the production of furanocoumarins in citrus ...

In research published in Advanced Intelligence Systems, scientists have developed an innovative, soft, wearable robot to help workers avoid job-related injuries while lifting, lowering, and carrying objects. While many available wearable robots are limited to supporting a single degree of freedom of the body (meaning the body can only move in one direction at a given joint), the new robot, called WeaRo, operates through multiple degrees of freedom, allowing for complex movements. In tests, WeaRo effectively reduced the muscle activation levels of lumbar, biceps, and triceps muscles by a maximum of 18.2%, 29.1%, and ...

In a recent study published in the American Journal of Industrial Medicine, middle aged workers in the U.S. who reported high job strain at the start of the study experienced significantly more sleep disturbances over an average follow-up of nine years. The study analyzed data from 1,721 workers, with an average age of 51 years, who participated in the Midlife in the United States (MIDUS) study. Sleep disturbances were assessed with an established scale, based on four sleep-related symptoms: trouble falling asleep, waking up during ...

Researchers have developed a novel method to assess depression in CEOs by using machine learning models (a type of artificial intelligence) to analyze vocal acoustic features from conference call recordings. This innovative approach, detailed in an article published in the Journal of Accounting Research, provides insights into a mental health issue that often remains hidden in high-pressure executive roles. The researchers examined how CEO depression is related to career outcomes, compensation, and incentives. Their findings suggest ...

The practice of growing different but complementary plants within a given area, also known as intercropping, has numerous positive effects such as reduced soil erosion, weed suppression, nitrogen fixation (the conversion of atmospheric nitrogen to nitrogen compounds that can be used by plants and other organisms), and pollinator benefits. New research published in Agrosystems, Geosciences & Environment reveals the increased land use efficiency and environmental benefits in an alfalfa–almond intercropped ecosystem ...

Overfishing, illegal fishing and increasing marketing of shark meat pose significant threats to the more than 80 species of sharks and rays that inhabit the Mediterranean Sea, according to a new study. The research examined current levels of legislation in place to protect elasmobranch populations (which include sharks, rays and skates) within each of the 22 coastal states of the Mediterranean region. Across those countries – stretching from Spain and Morocco in the west to Israel, Lebanon and Syria in the east – the researchers identified more than 200 measures that concern elasmobranchs in some ...
