Brazilian researchers have developed a new biomaterial made from jackfruit latex, pomegranate peel extract, and simvastatin (a statin-based drug). This could provide a more effective way to treat periodontitis, a serious periodontal disease. A team from the Faculty of Medicine and Health Sciences (FCMS) at the Pontifical Catholic University of São Paulo (PUC-SP) in Sorocaba developed the material as part of an effort to improve treatment options for conditions that affect the tissues that support teeth. Periodontitis is a chronic inflammatory disease caused by infection. Over time, the structures that hold teeth in place can break down, leading to loss…

Short videos shown in hospital neonatal rooms may be an effective way to educate first-time fathers about infant care topics such as safe sleep, infant crying, and car safety, according to a pilot study published in the journal Pediatrics Open Science. These topics were selected as common parental knowledge gaps and successful targets of previous educational interventions for mothers. ”New fathers often report feeling like bystanders in medical settings, as parenting support focuses primarily on the mother from pregnancy to postpartum.“The study was supervised by Craig Garfield, M.D., an expert on the role of fathers in child development at the…

Listening to specific music frequencies is associated with distinct biological changes in students experiencing exam-related stress. Recent research published in brain and behavior The 528 Hertz frequency tends to promote proteins associated with brain health, while the 432 Hertz frequency suggests that it triggers a cellular stress response. Despite these biological changes, short listening sessions do not immediately change cognitive performance on attentional tasks. University students often face intense pressure and anxiety during exam periods. This stress affects both your body and your mental focus. To cope with this pressure, many students turn to simple ways to relax, such as…

One of the biggest unsolved problems in physics centers around a number known as the cosmological constant. This value represents the energy responsible for the accelerating expansion of the universe. It is also at the center of a major conflict between two of science’s most successful theories. According to quantum field theory (QFT), a framework that describes elementary particles and their interactions, empty space should be filled with quantum fluctuations that yield enormous amounts of energy. In fact, calculations show that the cosmological constant should be so large that it virtually approaches infinity. But if you look, you’ll see something…

Astronomers may be close to solving a long-standing mystery about the universe’s largest galaxy. Observations by the X-ray Imaging Spectroscopy mission, known as XRISM, provide new evidence that supermassive black holes may be preventing these massive galaxies from forming as many stars as expected. According to current models, the most massive galaxies should contain more stellar mass than astronomers actually observe. This deficiency suggests that some process is suppressing star formation. Shin “Cindy” Xiang, a doctoral student at the University of Michigan, used XRISM data to explore one leading explanation and found direct evidence for a black hole. Most people…

Imagine if one company could become the rail, power company, and cloud computing provider for the emerging space economy. That possibility added to the excitement surrounding SpaceX’s long-awaited initial public offering. Investors are no longer just betting on rockets. They are betting on the entire ecosystem in orbit. Among the most ambitious and challenging ideas riding on this wave of enthusiasm is one that sounds almost like science fiction: orbital data centers. SpaceX may be one of the most well-known companies looking to build them, but it’s not the only one. The logic is fascinating. Once a data center is…

Many of the world’s most important crops have unusually complex genomes, created by repeated replication and hybridization of their entire genomes. These so-called polyploid genomes contain multiple sets of chromosomes inherited from different ancestral species. But determining exactly how their genomes were assembled can be very difficult, especially if the original ancestral species is extinct or unknown. New research introduces a genome-wide approach to unraveling these complex genetic histories. This method takes advantage of the evolutionary footprint left by long terminal repeat retrotransposons, a type of mobile DNA sequence. By comparing the similarity patterns of these elements across chromosomes, researchers…

Researchers at the University of California, Riverside have proposed a new explanation for how Alzheimer’s disease begins. The disease is not primarily caused by plaque buildup in the brain, but may begin when one protein interferes with the normal functioning of another protein in nerve cells. For many years, research into Alzheimer’s disease has focused primarily on amyloid beta (a-beta), a protein that forms clumps in the brains of Alzheimer’s patients. This idea gained support because genetic mutations that increase alpha-beta levels can cause early-onset Alzheimer’s disease. However, despite thousands of clinical trials designed to eliminate alpha-beta, these treatments have…

Nearly all Michiganders over 50 say keeping their brain healthy as they age is extremely important, according to a new poll. However, less than half (47%) of middle-aged and older Michigan residents know that daily actions are very important to reduce future dementia risk. And fewer than half practice at least one of the four important habits that can protect your brain health as you age, every day or almost every day. The poll results come at a time when research is clearly linking dementia risk to lifestyle factors such as what people eat and drink. amount of sleep, social…

High-income countries that began widespread administration of the human papillomavirus (HPV) vaccine in the mid-2000s recorded significant medical gains, with significant reductions in cervical cancer cases. new research in lancet Researchers at Queen Mary University of London (Queen Mary) suggest that the vaccine may also be responsible for the near-complete protection against death from cervical cancer in women under 30 in the UK who were vaccinated between the ages of 12 and 18, in one of the few analyzes of the impact of the HPV vaccine on mortality. The results of the study by Queen Mary researchers Peter Sasieni and…
