The Madrid bombings resulted in over 2,000 injuries, with 312 patients taken to GMUGH. Immediate triage and evacuation procedures helped prevent medical staff from being overwhelmed, saving the lives of more than 80% of critically injured patients.
Astronomers study remnant of 1,000-year-old supernova to solve long-standing puzzle of cosmic ray origin. They create gamma-ray image using Cherenkov radiation, providing first unequivocal proof that supernovae produce galactic cosmic rays.
A team of researchers has identified three genetic suppressors of RNA silencing in plants, which are crucial for combating citrus tristeza virus (CTV) infections. These viral suppressors can be targeted by genetically engineering virus-resistant citrus trees, offering a promising approach to disease control and reducing economic losses.
Scientists have successfully grown sperm progenitor cells in a laboratory culture, paving the way for potential new treatments for male infertility. The breakthrough, led by Hiroshi Kubota, could also enable the creation of genetically modified animals and extend the reproductive life of endangered species.
Researchers found that activated STAT3 is necessary for skin cancer development, and inhibiting it can prevent tumor growth. A STAT3 inhibitor could potentially be used as a topical cream to treat sunburns or precancerous lesions.
Boston University chemist Thomas Tullius receives NIH grant to develop ENCODE technology for mapping protein-binding sites. His research aims to decipher patterns on DNA's landscape, building tools to understand how structure affects function.
A retrospective cohort study of 198 children who underwent fundoplication at Texas Children's Hospital from 1996-1999 found that fundoplication is not a long-term solution for treating GERD in children. Alternative medical treatments, such as histamine-2 receptor antagonists and proton pump inhibitors, are recommended instead.
Krill populations in Antarctica have declined dramatically, with an 80% drop since the 1970s, primarily due to warming and reduced sea-ice. This decline has significant implications for commercial fisheries and the region's unique wildlife, which rely on krill as a food source.
Dr. Paul Ribbe will be honored with a symposium for his significant advances in the crystallography of feldspars, which led to the creation of definitive work on mineralogy. The symposium features keynote addresses from internationally recognized scientists and explores the 'micro to macro' approach pioneered by Ribbe.
A research team has identified a possible genetic mechanism behind congenital heart defects, using mouse models to study the protein Baf60c. The findings suggest that suppressed levels of this protein may lead to dramatic cardiovascular defects.
Researchers found that human activities, mainly agriculture and construction, cause more soil erosion than all natural processes combined. This situation is particularly critical due to the rapid growth of the Earth's population and widespread land use.
A recent study has identified PITX3 gene mutations as a significant cause of congenital posterior polar cataracts in four unrelated families. This finding offers new hope for preventing and treating this condition, which is the leading cause of blindness globally among children. The researchers believe that identifying these gene mutat...
Researchers aim to understand why some generations exhibit higher rates of violence in adolescents, using data from the Pittsburgh Youth Study. The study will examine age groups and potential cultural or economic factors influencing violence.
Researchers at Saint Louis University discovered a new flu vaccine solution that uses lower doses in younger adults, which could stretch the nation's vaccine supply by up to 2.5 times. This innovative approach involves administering the vaccine intradermally, between the layers of skin, rather than through a traditional muscle injection.
Scientists use DNA technology to identify specific art materials and develop biological preservation strategies to combat insect and fungal damage. A regional symposium on cultural heritage conservation is also organized, attracting over 100 curators and students.
Researchers at The Wistar Institute have identified a protein called 53BP1, which recognizes molecular sites in chromatin to detect DNA breaks. This protein is responsible for activating the p53 cell-death program, preventing cancer, and has been found to work through a specific mechanism involving nucleosome structure.
The SARS outbreak highlighted the importance of preparedness and response in hospitals. Quarantine strategies proved ineffective as most cases were acquired in hospital settings. In contrast, Taiwan successfully replaced quarantine with better preparedness for future pandemics.
Researchers at the University of Pennsylvania School of Veterinary Medicine have identified key growth factors essential for sustaining spermatogonial stem cells in culture. By understanding these factors, scientists hope to develop new fertility therapies and create sperm in vitro.
Researchers found a link between chronic allergic stimulation and an increased risk of leukemia and non-Hodgkin's lymphoma in adults. Childhood eczema also appeared to increase the risk of this condition, although its impact is still relatively rare.
Researchers at Cornell University have discovered a new DNA enzyme, AIRs kinase, with a shape similar to other members of the riboside kinase family. This finding suggests that proteins may evolve using similar rules, and could lead to the design of laboratory tools for testing anticancer drugs.
The Stanford Environmental Molecular Science Institute will investigate how heavy metal contamination interacts with solid surfaces and bacteria using various molecular-level tools. The institute aims to understand the structure and properties of pollutants like arsenic, chromium, and lead at a fundamental level.
Scientists at Bristol University analyzed a Roman canister containing cosmetics and recreated the 'foundation' cream, finding it composed of refined animal fat, starch, and tin. The researchers concluded that tin was used as a pigment due to its non-toxic properties.
A team of researchers from Bristol University and Saratov University in Russia analyzed 675 specimens of amphibians and reptiles from 289 areas spanning 13 geological time zones. The study found a profound loss of animal groups and ecosystems, with many species still absent after 15 million years of recovery.
