The immune system relies on molecular alarms that sense danger within cells. One of these alarms is STING (short for “stimulator of interferon genes”). STING helps cells respond to infections, DNA damage, and cancer. When activated at the right time, it protects the body. If it is activated too easily or if it fails, it can cause disease. STING controls several immune responses, including the production of type I interferon, an antiviral molecule that helps coordinate immune defenses. It also controls inflammatory signals and a process called non-canonical autophagy that helps cells respond to stress and infection. Despite its importance,…

Despite the devastating damage caused across SA this year, public understanding of harmful algal blooms remains low, a survey has found. It comes amid a push to better prepare the country for the possibility of further outbreaks in the coming years.Australian National University medical anthropologist and associate professor Amy McLennan is among a group of trained volunteers, including marine scientists, epidemiologists and disaster experts, who came together during SA’s harmful algal bloom (HAB).Their survey, called “Algal Bloom Shed,” found that 57.2% of respondents identified a cause that is not scientifically thought to be the main factor in bloom outbreaks, and…

Just because cameras start recording statehouses doesn’t mean politicians actually change their voting behavior or result in more polarization. According to a recent study published in the American Political Science Review, the new findings suggest that live streaming political proceedings does not impede the policy-making process. For decades, political observers have debated the impact of video transparency on government agencies. Some argue that installing cameras in legislative buildings would make it easier for everyday voters to monitor their elected officials. According to this theory, increased visibility should encourage politicians to compromise and act with moderation, fearing public backlash if they…

The transaction amount is approximately $27,000 for each plaintiff. Some victims of water pollution say that’s not enough. Nearly 630 plaintiffs affected by naval water contamination in central Oahu will receive payments totaling $17 million in the latest Red Hill court settlement announced Wednesday by the U.S. Department of Justice. Justice Department leaders touted the move as a good-faith step toward solving a problem in which tens of thousands of gallons of jet fuel spilled in 2021 sickened scores of service members, their families, and civilians. However, some victims called the deal a “slap in the face” and said it…

Recent research published in nature communications We provide evidence that an evolutionarily ancient group of brainstem neurons is required for the brain to filter out distractions and focus on important spatial information. This finding indicates that these particular inhibitory cells are specialized in helping the animal select the correct target of attention, without affecting basic perception or body movements. The discovery of these neurons in mice could be the first step toward developing targeted therapies for attention disorders. To navigate complex environments, animals must constantly filter sensory input to select the most important information. The importance of a stimulus, known…

Black neighborhoods in Hartford, which have historically faced discriminatory redlining policies, are most likely to be contaminated with high levels of lead in the soil, according to a new study from the University of Vermont.These neighborhoods (Clay Arsenal, Downtown Hartford, and Sheldon-Charter Oak) were rated as “least desirable” by the Federal Housing Authority in the 1930s, receiving the lowest “D” grade and marked in red on the city’s historic redlining map. Banks often denied mortgages to people living in red-light areas or charged higher interest rates, even if the borrower was able to repay the loan.”The most important parameter in…

Employees in the healthcare industry are moving beyond emergency coverage to a “more purposeful” workforce strategy across their organizations, according to a new report from Definitive Healthcare. Using a proprietary algorithm based on claims activity and affiliation data, the data analytics firm estimated that the number of locum tenens professionals has increased by more than 23% since 2022. Definitive’s 2026 Providers: Industry Pulse report draws insights from proprietary data and analysis, as well as third-party research, to identify four key workforce shifts across industries. The report aims to give leaders and organizations “a deeper understanding of the current state of…

David Engblom, professor of neurobiology at Linköping University in Sweden, has been awarded the 2026 Onker Adam Prize for outstanding research at Linköping University Faculty of Medicine. He studies the brain’s role in making you feel sick in various medical conditions. Think about how you felt the last time you had a cold or flu. Have you been feeling a little depressed, avoiding interacting with others, and feeling diffusely unwell? Perhaps. This type of depression is caused by inflammation in the body activating the immune system, and can also occur in lifelong conditions such as rheumatoid arthritis and inflammatory bowel…

A new study of lung cancer screening participants finds that low-dose chest computed tomography (CT) tests are generally well tolerated physically and mentally, but experiences vary by socio-economic group. Low-income groups and safety net participants faced greater test-related burdens and increased discomfort and anxiety due to factors such as insurance and employment status. The survey results are: Journal of the American College of Radiologya paper published by Elsevier, highlights opportunities to improve fairness in review. Lung cancer is the leading cause of cancer death in the United States, and early detection of lung cancer saves lives. In the real world,…

A recent experiment revealed that hormones related to social bonding lead heterosexual men to collaborate more often with female partners in computerized games, regardless of whether the women are presented in sexual terms. The researchers discovered that this hormone specifically encourages men to forgive betrayal under certain conditions, revealing the biological basis of social and mating behavior. These results were published in Psychoneuroendocrinology. Society is highly saturated with sexual images, prompting psychologists to investigate how emphasizing a person’s sexual nature changes social perceptions. Sexual objectification often leads to sexual objectification. This cognitive shift occurs when individuals reduce to the status…
