New research demonstrates that silver diamine fluoride (SDF) is as effective as dental sealants in preventing tooth decay among over 4,000 elementary school students, offering a less expensive and quicker application process. This alternative treatment not only prevents cavities but also represents a significant cost-saving measure that can increase access to dental care, particularly in school-based cavity prevention programs.Silver diamine fluoride prevents cavities and keeps existing ones from worsening in school-based…

A new study reveals that a specific DNA insertion in the TBXT gene could be why humans and apes lack tails, unlike monkeys. This groundbreaking research provides insight into the genetic basis of tail loss in primates and suggests an evolutionary trade-off that might relate to certain birth defects in humans.Exploring the process of change could uncover novel functions for elements of the genetic code.A new study conducted by researchers at NYU Grossman School of Medicine suggests that a genetic change in our ancient…

A study has linked phthalates, chemicals in plastics and cosmetics, to nearly 56,600 preterm births in the U.S. in 2018, with costs up to $8.1 billion. It underscores the health risks of phthalates, such as hormone disruption and lower newborn weights, advocating for stricter regulation to mitigate the impacts on public health and the economy.A recent study suggests that regular contact with chemicals found in plastic food packaging and numerous cosmetic products could be linked to approximately 56,600 premature births in…

Researchers studying tomb epitaphs from medieval China’s Tang Dynasty have uncovered evidence that education significantly influenced social mobility, similar to its role in modern times. The Imperial Exam, or Keju, was identified as a key factor in promoting meritocracy over aristocracy, illustrating the long-standing impact of education on career advancement and social status.

The stone tool was glued into a handle made of liquid bitumen with the addition of 55 percent ochre. It is no longer sticky and can be handled easily. Credit: Patrick SchmidtAnalysis of tools that are 40,000 years old has revealed a surprisingly sophisticated level of construction.A team of researchers has found that Neanderthals crafted stone tools using a sophisticated multi-component glue. This discovery, the oldest known example of such an advanced adhesive in Europe, indicates that these early human relatives…

Recent research has identified brief seizures as a potential cause for the sudden, unexpected deaths of young children during sleep, shedding light on over 3,000 annual tragedies in the U.S. This study emphasizes the critical need for further investigation into seizures’ role in these deaths, offering new directions for understanding and prevention efforts.In research aimed at gaining insights into the sudden, unexpected deaths of young children, often happening during sleep, scientists have pinpointed brief seizures that…

Recent research demonstrates that blocking the attachment of virus particles to cell surface molecules in infant mice can significantly reduce the transmission of influenza A. This finding opens the door to new preventative strategies against seasonal flu, potentially supplementing existing vaccines and treatments with methods that target the host’s ability to spread the virus.Researchers have long understood that certain viruses and bacteria initiate infections by initially attaching to sugar molecules present on the…

Recent research on the fossil ape Lufengpithecus’s inner ear structures offers new clues to the evolutionary steps towards human bipedalism, revealing the significant roles of the inner ear and climate change in this evolutionary journey.

This photograph shows fluorescein dye being ejected from the sprinkler as it spins in forward mode. Credit: NYU’s Applied Mathematics LaboratoryScientists have solved the decades-old Feynman Sprinkler Problem, showing that a sprinkler running in reverse spins oppositely to when it ejects water. This finding deepens our understanding of fluid dynamics and could inform renewable energy development.For decades scientists have been trying to solve Feynman’s Sprinkler Problem: How does a sprinkler running in reverse—in which…

A recent study reveals that a combination of a monobody and MMAE effectively stops blood cancer cell growth in mice, focusing on multiple myeloma. This approach targets RAS mutations in cancer cells, offering new potential in treating relapsed cases and enhancing existing cancer therapies.A new study in mice has revealed that a specific drug combined with a protein fragment can prevent the growth of blood cancer cells.This research focused on multiple myeloma, a type of cancer that originates in blood cells responsible…
