The World Health Organization late Saturday declared the Ebola outbreak first identified in the Democratic Republic of Congo an international public health emergency, highlighting concerns about the spread of the virus, with travel-related cases reported in the capital Kinshasa and Kampala, Uganda. The speed with which the state of emergency was declared – Africa’s health authorities only confirmed the outbreak on Friday – is unusual but underscores concerns that authorities are behind the virus. A strain of Ebola called Bundibugyo is causing cases. Health authorities are inexperienced in dealing with this virus strain, with only two Bundibugyo outbreaks recorded so…

Climate change is steadily robbing rivers around the world of oxygen, according to a new study published on May 15th. scientific progress. The researchers found that this long-term oxygen loss occurs in most river systems, with tropical rivers being the most vulnerable. This finding indicates that strategies aimed at slowing oxygen loss in freshwater ecosystems are urgently needed. The research was led by Professor Kun Shi of the Nanjing Institute of Geography and Limnology, Chinese Academy of Sciences (NIGLAS). Dr. Qi Guan served as lead author, and researchers from Tongji University also participated in the project. A river loses its…

Scientists have discovered that a powerful cancer-associated protein does more than just promote tumor growth. It also helps cancer cells survive by repairing damaged DNA, a discovery that could ultimately improve treatments for the most deadly cancers. This study genes and developmentfocused on MYC, a protein that is abnormally active in most human cancers. Researchers at Oregon Health and Science University (OHSU) have discovered that MYC directly helps repair dangerous breaks in DNA, allowing tumor cells to recover from chemotherapy and other treatments designed to destroy them. By helping cancer cells repair this damage, MYC may contribute to treatment resistance…

While recent political debate has often focused on the shift of working-class voters away from the Democratic Party, new analysis provides evidence that another shift is actually driving the modern political divide. Over the past 40 years, high-income, highly educated, white-collar white voters have steadily moved toward the Democratic Party. These findings were recently published in the Proceedings of the National Academy of Sciences. Researchers Karin Bilbig and Paula Englund conducted the study to examine common theories about voting behavior in the United States. After the 2016 presidential election, many political commentators suggested that Donald Trump won because the white…

People with major depressive disorder or bipolar disorder whose brain activity increases when they see scary faces are at increased risk of being admitted to a psychiatric hospital within a year. This increased vulnerability is also accompanied by a complementary tendency to recognize negative facial expressions more quickly than positive facial expressions. These findings emerged from a recent study published in the journal Neuropsychopharmacology. Major depression and bipolar disorder are two of the most common and persistent mood disorders worldwide. Both health conditions can seriously disrupt a person’s life and, in some cases, cause periods of severe mental distress. The…

A woman’s reaction to an unfaithful partner may depend on a combination of personality traits, attachment style, and past romantic experiences. Research examining these personal characteristics suggests that certain behavioral tendencies are associated with whether a person forgives a cheating partner or stays in the relationship. The results of this study were published in The Journal of Psychology. When a romantic partner develops a secret sexual or emotional relationship with someone else, the betrayed partner often experiences immense pain. Infidelity is one of the most common reasons couples break up or divorce. For the cheated partner, discovering the affair can…

Recent research published in journals anatomy education We found that updating a scientific organization’s Wikipedia page improves public access to accurate information. This study suggests that when experts actively edit the entries in these digital encyclopedias, readers tend to view academic institutions as more trustworthy. These findings provide a practical roadmap for professional associations to increase their digital visibility and engage with broader audiences. Mike Pascoe, associate professor at the University of Colorado Anschutz and author of the study, conducted the study to address a glaring gap in online science communication. Wikipedia receives billions of visits each month and consistently…

A seven-year longitudinal study found that young people who experienced more unpredictable life events tended to have higher levels of activation in the fronto-parietal region of the brain during cognitive control tasks. As the brain matures, less effort should be required to complete these tasks, so this higher activation suggests that brain networks are becoming less efficient. This inefficiency, in turn, was associated with a reduced willingness to take active social risks (e.g., exploring new careers, voicing unpopular opinions, and starting conversations) in young adulthood. The paper is Social cognitive and affective neuroscience. Positive social risks are situations in which…

People with anxiety disorders may share measurable changes in brain chemistry related to choline, an essential nutrient associated with memory, mood, cell structure, and neural signaling. A study from the University of California, Davis Health found that people diagnosed with anxiety disorders had lower choline levels in their brains than people without anxiety. This discovery is molecular psychiatryin the journal Nature, provides a rare look at chemicals that may be associated with anxiety across several different diagnoses. The researchers reviewed data from 25 previous studies that measured neurometabolites, chemicals involved in brain metabolism. Overall, the analysis included 370 people with…

Mitochondria are often described as the powerhouses of the cell, but their role in the brain may be even more important than scientists once realized. These tiny structures provide the energy neurons need to communicate, form memories, and keep the brain working smoothly. In a study published in Nature Neuroscience, researchers from Inserm and the NeuroCentre Magendie at the University of Bordeaux, in collaboration with scientists from the University of Moncton in Canada, reported a major step forward in our understanding of dementia. Their results showed a direct causal relationship between defects in mitochondrial activity and cognitive symptoms associated with…
