Scientists have discovered new evidence that Earth is traveling through clouds of ancient stellar debris left behind by stars that exploded long ago. By studying Antarctic ice that formed tens of thousands of years ago, researchers detected traces of iron-60, a rare radioactive form of iron produced in supernova explosions. This discovery supports the idea that the local interstellar cloud surrounding our solar system contains material from ancient stellar explosions. The study was led by an international team from Dresden-Rossendorf-Helmholtzzentrum (HZDR) and the results were published in the following journals: physical review letter. Rare supernova iron discovered in Antarctic ice…

It looks like it’s going to be hot in North America this year. According to the National Weather Service’s Seasonal Temperature Outlook for the United States, temperatures are expected to exceed historical averages across the country in June and July. In this environment, 48 men’s national teams will come together to win the World Cup, which will be held in the United States, Canada, and Mexico.As the tournament approaches, The Guardian takes a closer look at the weather conditions players are likely to face, how they have changed since the last time the World Cup was held in North America…

Four new studies funded by the Ontario Cancer Research Institute (OICR) will deliver cutting-edge innovation by maximizing the impact of existing research and maximizing patient contributions. OICR supports research through CATALYST, a new funding source for research that leverages available patient data and donated samples to advance new insights into cancer detection, diagnosis, and treatment. The first four CATALYST studies, led by Ontario’s top researchers, are examining a wide range of innovative approaches, from blood tests that can predict the likelihood of head and neck cancer recurrence to evaluating whether common diabetes drugs can help prevent blood cancers. All four…

Researchers at the University of California, Davis have developed a light-driven technology that converts amino acids, the building blocks of proteins, into compounds that behave similar to psychedelics in the brain. These newly created molecules activate serotonin 5-HT2A receptors, which are associated with brain cell growth, and are considered promising targets for treating conditions such as depression, PTSD, and substance use disorders. However, unlike traditional hallucinogens, this compound did not cause significant hallucinogen-like behavior in animal studies. The survey results are Journal of the American Chemical Society. “The question we were trying to answer was, ‘Are there entirely new classes…

Does your baby put his arms through his sleeves when you dress him? Does your toddler pick up dropped shorts when you sort the laundry? These are examples of how toddlers can be helped by participating in shared activities. As infants reach their first birthday, helping becomes apparent in the context of sharing chores and interactions with caregivers, and fetching objects that are out of reach of unfamiliar adults. Researchers at the Ludwig-Maximilians-University of Munich in Munich, Germany, aimed to address this issue by investigating how infants’ helping behavior is related to motor development, social-cognitive skills, and early interactions with…

MIT engineers have developed a new method to amplify T cell responses to mRNA vaccines. This progress could lead to more powerful cancer vaccines and stronger protection against infectious diseases. Most vaccines produce both antibodies and T cells that can target vaccine antigens by activating antigen-presenting cells such as dendritic cells. In this study, researchers used a new type of vaccine adjuvant (a substance that helps stimulate the immune system) to boost T cell responses. The new adjuvant is composed of mRNA molecules that encode genes that activate immune signaling pathways and promote exaggerated T cell responses. In studies in…

Many drug and antibody discovery pathways focus on intricately folded cell membrane proteins. When drug candidate molecules bind to these proteins, they trigger a chemical cascade that changes cell behavior, like a key in a lock. Therefore, understanding how proteins fold and move is essential to developing drugs that interact well with their targets. Artificial intelligence (AI) is a very useful tool for generating new protein structures, but most systems, including Google DeepMind’s AlphaFold, focus on generating static “snapshots” of proteins. Subtle rearrangements of atoms within structures called side chains that affect the protein’s interactions with other molecules are not…

Medical images routinely used in cancer treatment may contain far more biological information than previously thought. An international study involving Umeå University Visiting Professor Lucas Kenner has shown that PET/CT scans can capture the molecular activity of particularly aggressive head and neck tumors, opening new possibilities for more accurate diagnosis and treatment planning. Most head and neck cancers are so-called squamous cell carcinomas that affect tissues of the mouth, throat, and larynx. HPV-negative tumors, that is, tumors that are not caused by the human papillomavirus HPV, tend to be more aggressive and difficult to treat. Reliable markers to predict how…

Seasonal influenza can spread rapidly, and timely information about rising numbers of cases is essential for public health decisions and health resource planning. However, traditional surveillance based on reported cases relies on health care-seeking behavior, laboratory tests, and reporting processes, which can lag real-world infection trends. A research team led by Professor Michio Murakami of Osaka University has demonstrated that measuring influenza virus RNA in wastewater can be used to estimate community influenza incidence. This approach could help identify trends in the epidemic about a week earlier than publicly available patient-reported data.This research Water and Environment Journalpresent a sewage-based epidemiology…

For female participants with myasthenia gravis, pregnancy was not associated with an increased risk of severe flare-ups of the disease or new or worsening symptoms, according to a study published in the journal May 13, 2026. Neurology®Medical Journal of the American Academy of Neurology. For a small number of people, the postpartum period up to the first year of life is associated with an increased risk of severe relapse. Myasthenia gravis is an autoimmune disease that causes muscle weakness. Affects voluntary muscles. Symptoms include droopy eyelids, double vision, slurred speech or low volume, difficulty chewing or swallowing, and muscle weakness…
