Hawaii faces a growing plastic waste challenge. Recycling on the islands is expensive and difficult, and large amounts of marine debris continue to wash ashore or remain in surrounding waters. Researchers are now exploring innovative solutions to turn discarded fishing nets and household plastic waste into asphalt for roads. Initial results suggest this approach could provide a practical new destination for plastics that would otherwise end up in landfills or oceans. Jeremy Axworthy, a researcher at Hawaii Pacific University’s Center for Marine Debris Research (CMDR), presented the findings at the American Chemical Society (ACS) Spring Meeting. “This study investigates whether…

Supereruptions are one of the most powerful volcanic phenomena on Earth. These large eruptions can release more than 1,000 cubic kilometers of magma, rock, and ash, with dramatic impacts on climate, ecosystems, and human societies. Because of their impact, scientists are working to better understand the underground processes that create and sustain these giant volcanoes. Researchers at the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS) have recently developed a detailed three-dimensional model of western North America that simulates the current behavior of the lithosphere and underlying mantle. Their research revealed a new explanation for how magma is…

Long-term research has found that even occasional visits from mountain lions can rebuild entire ecosystems. Researchers studying a small suburban preserve about 45 miles south of San Francisco found that as mountain lion activity increased, the behavior of many other animals changed as well. The impact extended beyond wildlife, affecting plant growth and the overall health of the landscape. mountain lion (puma conqueror) began to appear frequently on trail cameras at Stamford’s Jasper Ridge Biological Preserve (‘Auchamin’ Auyakuma) from 2015 to 2020. Researchers observed a decline in deer activity during the same period compared to earlier periods when mountain lions…

Teenagers who use cannabis may be more likely to develop serious mental illness by young adulthood, according to a major new study published in . JAMA Health Forum. Researchers followed 463,396 adolescents between the ages of 13 and 17 to 26. Teens who reported using cannabis within the previous year were found to have a significantly higher risk of developing psychotic disorders, bipolar disorder, depression, and anxiety disorders later in life. Among adolescents who used cannabis, the risk of both psychotic disorders and bipolar disorder approximately doubled. The study was conducted by researchers at Kaiser Permanente, the Public Health Institute’s…

Astronomers have glimpsed the inner workings of a dying star in a rare type of cosmic explosion called an “extremely stripped supernova.” In a paper published in natureSteve Schultz of Northwestern University and colleagues describe supernova 2021yfj and the thick shell of gas that surrounds it. Their findings support existing theories about what happens inside massive stars at the end of their lives and how they have shaped the building blocks of the universe we see today.How stars make elementsStars are powered by nuclear fusion. Fusion is a process in which lighter atoms are crushed into heavier atoms, releasing energy.…

An international analysis combining brain imaging data from multiple independent studies has identified common patterns in how psychedelic drugs alter communication between different brain networks. Researchers have found that substances such as psilocybin and LSD reliably increase functional connectivity between brain regions responsible for sensory input and brain regions involved in abstract, associative thinking. The research results were published in a magazine natural medicine. In recent years, classic psychedelic drugs such as psilocybin, LSD, and DMT have re-entered the mainstream of psychiatric research as experimental treatments for conditions such as depression and anxiety. All of these substances reliably bind to…

When negotiating with a woman, people tend to be more satisfied and enthusiastic about the upcoming interaction. Recent research is Proceedings of the National Academy of Sciences This suggests that women achieve the same economic outcomes as men while simultaneously fostering better interpersonal relationships. The strength of these relationships provides evidence that women are better at the social aspects of transactions, which may lead to compounding economic advantages over time. Negotiation is essentially a discussion aimed at reaching an agreement where parties may have conflicting or common interests. These conversations happen everywhere, from discussions about formal job pay to everyday…

New research published in oncology science Glioblastoma is exploring a potential new approach to the treatment of brain tumors, a malignancy that remains extremely difficult to treat. The paper is titled “Selective blood-brain barrier penetration and tumor targeting of nitrosylcobalamin in glioblastoma: pharmacokinetics, tissue distribution, and synergistic activity with TRAIL and temozolomide.” The study was led by first and corresponding author Joseph A. Bauer of Nitric Oxide Services, LLC and Cleveland Clinic Foundation Taussig Cancer Center. The research team investigated nitrosylcobalamin (NO-Cbl), a modified form of vitamin B12 that releases nitric oxide, to see if it could cross the blood-brain…

Practicing a specific type of slow, guided breathing every day for eight weeks reduces the body’s fight-or-flight response to psychological stress in veterans dealing with post-traumatic stress disorder. The findings suggest that consistent breathing exercises may help protect long-term cardiovascular health in people with trauma-related mental illness. The study was published in the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology. Post-traumatic stress disorder is a severe mental health condition that develops after experiencing a frightening event. People with this disease have a much higher risk of developing high blood pressure and heart disease later in life. This increased risk…

Big life events can shape personality, but their impact varies greatly depending on who experiences them and how they interpret them. That’s the conclusion of a new study published in the journal Nature. personality journal. The study found that factors such as age, gender, a person’s perceptions, and even who is assessing their personality influence whether an event is associated with lasting change. Although personality traits are often viewed as relatively stable traits, research has shown that people can change over time. Events such as entering into a romantic relationship, becoming a parent, experiencing illness, and changing jobs have all…
