Research by Brigham Young University geologists reveals Hawaiian Islands are dissolving from within, with groundwater removing more mineral material than stream water. The study predicts Oahu will continue to grow for up to 1.5 million years before eventually declining in elevation.
Researchers used an X-ray free-electron laser to determine the structure of trypanosomal Cathepsin B, a promising target for treating sleeping sickness. The study provides detailed insight into how the naturally occurring native inhibitor binds, offering new ideas for designing targeted treatments.
Scientists at the University of Luxembourg have developed a new calculation technique that accurately predicts the B-Z transition in DNA, which can lead to cancer. The breakthrough enables the prediction of material properties such as melting temperatures and elasticity with high accuracy.
A study led by Columbia University Medical Center researchers found that an important branch of the immune system mounts a surprisingly robust anti-inflammatory T cell response to prevent atherosclerosis progression. Regulatory T cells suppress pro-inflammatory effector T cells and macrophages, reducing disease severity.
A new UCSF study examines the role of key molecule PKCγ in regulating the food clock, which is disrupted by irregular eating patterns. The findings have implications for understanding diabetes, obesity, and other metabolic syndromes.
Researchers say targeting extraoral taste receptors in the gut could release hormones that signal fullness, mimicking meal effects and aiding weight loss. Additional studies are needed to identify effective drug targets for obesity treatment.
A new study challenges previous views on miR-205's function in breast cancer. Research found that miR-205 is overexpressed in transformed cells and contributes to the abnormal morphology of acini. The findings suggest miR-205 can act as an oncogene, promoting cell growth or inhibiting apoptosis.
Eczema is a persistent skin rash that can be triggered by inadequate Ctip2 protein, leading to inflammation and immune dysfunction. Researchers have identified two ways in which improper Ctip2 function contributes to eczema, paving the way for personalized treatments and new therapies.
New research sheds light on the complexities of learning problems in neurofibromatosis 1 patients. The study found that both increased RAS function and reduced dopamine levels contribute to cognitive dysfunction in individuals with NF1. Developing personalized therapies is now a priority.
NASA's Hubble Space Telescope has been providing amazing images of the universe since April 1990, while the next-generation James Webb Space Telescope will reveal mysteries of the universe in much greater detail. The new free e-Books offer interactive resources and insights into both telescopes' science and technology.
The new dedicated network, Science DMZ, will enable WSU researchers to transmit and receive large amounts of data quickly, across the campus or around the world. This upgrade will greatly speed up their ability to work, moving research forward with faster downloads and improved collaboration.
Researchers found that six weeks of resistance training significantly improved blood markers of cardiovascular health in young African-American men, but not Caucasian men. This suggests that resistance exercise training is more beneficial in young African-American men.
Researchers found that Xbp1s regulates liver metabolic switch after eating, while low iron accelerates H. pylori-induced gastric cancer. Additionally, p62 is crucial for brown fat thermogenesis, and dendritic cells play a protective role in atherosclerosis.
Scientists have identified a new type of nerve cell in the brain that regulates heart rhythm and blood pressure. The discovery may lead to new ways of treating cardiovascular diseases.
Forensic experts at Uppsala University identified the remains of Carin Göring, wife of Nazi leader Herman Göring, through DNA analysis. The researchers matched mitochondrial and nuclear DNA with historical records, confirming her identity.
Researchers analyzed over 400 patient records to find that the proportion of early-stage lung cancer cases identified by CT scans increased by almost 50% during a recent 10-year period. However, only half of these cases would meet criteria for lung cancer screening under existing guidelines.
Drs. William Y. Kim and James W. Mier have received $250,000 grants to conduct innovative translational kidney cancer research. Their projects aim to personalize kinase therapy and explore the mechanism of HDM2 antagonists in blocking tumor angiogenesis.
Research found that low iron levels accelerate H. pylori-induced carcinogenesis in rodents and humans, increasing the risk of gastric cancer. Iron deficiency is associated with more virulent H. pylori strains and greater inflammation, highlighting the importance of iron levels in identifying high-risk patients.
The study reveals differences in the speed of evolution among globular clusters, with fast-aging clusters experiencing core collapse within a few hundred million years. In contrast, slow-aging clusters would take several times the current age of the universe to undergo core collapse.
Research suggests that cooler climates led to increased biodiversity in marine fauna, while warmer temperatures caused species to become extinct. The study's findings indicate that climate fluctuations played a significant role in the emergence and extinction of species.
Theoretical physicists created models to study van der Waals-Casimir-Polder (vdW-CP) force, which depends on electron diffusion. This finding could contribute to designing minimally invasive surface probes for quantum computer hardware architectures.
A five-year NIH grant supports a program to develop resident genomic pathology curriculum, expanding pathologists' role in interpreting and acting on genomics data. The initiative aims to bridge the gap between genetic research and practical application in patient care.
Researchers Xiao-Gang Wen and collaborators introduce a new system for classifying symmetry-protected phases of matter, potentially increasing our ability to design states of matter for superconductors and quantum computers.
