Do you have trouble sleeping? The reason may partly depend on your age. A recent study involving psychology researchers from Binghamton University and the State University of New York investigated how sleep deprivation alters brain communication across the adult lifespan, and specifically examined how these changes vary by age and biological sex. The article “Sleep quality has different associations with default mode and salient network connectivity by age and gender” was published in the latest edition of the journal. Neurobiology of aging. Co-authors include Binghamton University psychology graduate student Separ Gulabi and associate professor of psychology Ian McDonough. Selene Tan,…
The Center for Vaccine Development and Global Health (CVD) at the University of Maryland School of Medicine announced the start of a research study to understand how Lassa fever survivors fight and overcome Lassa virus infection. The study, titled “Identification and Immunological Characterization of Adult Lassa Fever Survivors in Nigeria,” is a collaboration between CVD, the International Research Center for Human Virology (IHVN) of Nigeria (IRCE), and the Abubakar Tafawa Balewa University Teaching Hospital (ATBUTH) in Bauchi State. Lassa fever remains one of the most serious and persistent public health threats in Nigeria and other endemic regions of West Africa.…
More than half (57%) of children born before 32 weeks of age were not ready for school at age five, including in areas such as communication, language, and physical and emotional development. Those born prematurely at 23 to 24 weeks were up to three times more likely to miss expected developmental milestones than those born at 31 weeks. The study also found that children born in the most deprived areas were up to twice as likely to have low attainment compared to children born in the least deprived areas. Experts say strategies that reduce social inequalities, promote brain health and…
Recent research published in quarterly public opinion They provide evidence that requiring people to vote does not automatically increase interest in politics or support for democracy. This study suggests that removing penalties for not voting significantly reduces electoral participation, but leaves people’s political engagement and democratic attitudes almost unchanged. Compulsory voting is a system in which eligible citizens are legally required to participate in elections. In many of the approximately 25 countries that use this system, failing to vote can result in fines and other penalties. Supporters of compulsory voting often argue that forcing people to attend polling places encourages…
A commercial spaceflight crew team took the first diagnostic X-rays during an orbital flight. The results of the mission were announced today. RadiologyJournal of the Radiological Society of North America (RSNA). For aerospace medicine, it has been a dream to have multiple imaging modalities for diagnosing diseases and injuries in space. X-ray examinations are quick, easy, and of diagnostic value. ” Dr. Shayna Gifford, Chief Investigator and Assistant Professor of Aerospace Medicine, Mayo Clinic, Rochester, Minn. For more than 40 years, ultrasound has been the only reliable medical imaging modality used in spaceflight. As the duration and distance…
Acute respiratory distress syndrome (ARDS) remains one of the most lethal complications of severe infections, sepsis, trauma, and viral pneumonia, but decades of research have yielded few targeted therapies that can improve patient outcomes. A new review has been published Ferroptosis and oxidative stress suggests one reason for this treatment gap. Researchers may have focused on individual cell death pathways and overlooked the complex networks that connect them. This review proposes a new perspective on the pathogenesis of ARDS, arguing that multiple forms of controlled cell death (RCD), including apoptosis, necroptosis, pyroptosis, ferroptosis, and other programmed death mechanisms, do not…
K2-18b has become one of the most interesting exoplanets in recent years. The planet is located approximately 124 light-years away in the constellation Leo, orbiting within the habitable zone of a red dwarf star. Observations by the James Webb Space Telescope have revealed the presence of an atmosphere rich in carbon dioxide and methane, making K2-18b one of the leading candidates for a “Hycean” world, where a thick hydrogen-rich atmosphere could surround a global ocean of liquid water. K2-18b is also a prime target for the Search for Extraterrestrial Intelligence (SETI) because of its potential to host conditions favorable to…
A study has found that 20 minutes of moderate treadmill exercise helped both young and older men react faster on tests of attention and self-control. mental health and physical activity. The results of this study suggest that even brief movements can temporarily sharpen mental processing without reducing accuracy. Although exercise is often discussed in relation to long-term physical health, researchers have also found that even a single bout of exercise can affect the brain. One area of interest is inhibitory control, or the ability to ignore distractions and focus on what’s important. This ability is important in everyday life, from…
Can eating lots of chili peppers affect your cancer risk? Scientists have been debating this question for years, but the answer is still not simple. Chili peppers contain compounds that have been shown to have anti-inflammatory and even anti-cancer properties in laboratory experiments, but some human studies have linked consumption of very high amounts to an increased risk of certain gastrointestinal cancers. Extensive review published in Frontiers of nutrition After reviewing the available evidence, we found that people who consume the most chili peppers are more likely to develop certain gastrointestinal cancers, particularly esophageal cancer. At the same time, the…
The Ebola outbreak in eastern Congo “continues to outpace response efforts,” the World Health Organization’s emergency chief said on Tuesday after returning from a trip to Bunia in Ituri province, one of the worst-hit areas. “Perhaps the most worrying finding is that many of the newly reported deaths are people who died in the community without ever going to a health facility or receiving care,” Chikwe Ihekwazu said. “And as of today, 80% of new infections are outside our contact list, so they are coming to us from unknown transmission routes.” Congo has been battling an outbreak of a rare…
