Researchers in Japan think they have found an answer to the fundamental biological question of how individual cells know which way to position themselves within a complex, multicellular body. Depending on a cell's purpose in the larger structure, contact or diffuse chemical signals direct it to its final destination.
MIT and Harvard University researchers have developed Riverbed, a platform that ensures web and mobile apps using distributed computing in data centers adhere to users' preferences on how their data are shared and stored in the cloud.
Researchers from Case Western Reserve University in Ohio report their insights into how colors are generated on heated metal surfaces and apply those findings to create a nickel thin-film that perfectly absorbs red light.
Researchers have documented a group of tanner crabs vigorously feeding at a methane seep on the seafloor off British Columbia -- one of the first times a commercially harvested species has been seen using this energy source.
Researchers from Russian Academy of Sciences developed a new method for star-shaped nanoparticles synthesis based on laser irradiation. A wide range of customizable conditions provides an opportunity to create comfortable environment for various substances delivery to different types of cells. The results are published in Journal of Biophotonics. The research was supported by the Russian Science Foundation.
Study shows that acetate, an acid found in some foods, may help doctors intervene when seizures are imminent.
Tropical Depression 02W has organized and strengthened into a tropical storm.
A new observation, led by researchers at the Duke Human Vaccine Institute, highlights the importance of previously unstudied mutations that arises early in bnAbs, giving the antibodies the flexibility to adapt to changes in the virus's outer envelope protein structure. This flexibility enables the antibody to dock on diverse strains of the virus and more potently neutralize them.
Salt apparently affects allergic immune reactions. A team working with Professor Christina Zielinski at the Technical University of Munich has demonstrated in cell cultures that salt leads to the formation of Th2 cells. These immune cells are active in allergic conditions such as atopic dermatitis. The team also detected elevated salt concentrations in the skin of patients.
Tropical Cyclone Oma is a large hurricane with a big eye. The storm appeared well-organized on satellite imagery as it moved through the Southern Pacific Ocean.
Naturopathy, or 'naturopathic medicine' as the profession is branded in the United States, is a rapidly growing profession and scientifically advancing form of practice that can have a positive impact on a wide variety of chronic and complex conditions.
Vigorous exercise, fasting, hormones improve elimination of toxic, misfolded, unnecessary proteins in mouse and human cellsWednesday February 20th, 2019 05:00:00 AM
A new study shows vigorous exercise and fasting improve the ability of human and mouse cells to remove misfolded, toxic, unnecessary proteins. The findings reveal a previously unknown mechanism that activates the cells' protein-disposal machinery, allowing them to adapt their protein content to shifting demands and new conditions.
In the largest study of its kind, researchers at the University of Colorado Anschutz Medical Campus have found new clues into the parts of the human genome associated with the higher rates of asthma in those of African ancestry.
When a stream of charged particles known as the solar wind careens onto the moon's surface at 450 kilometers per second (or nearly 1 million miles per hour), they enrich the moon's surface in ingredients that could make water, NASA scientists have found.
Fossil fuel combustion is the main contributor to black carbon collected at five sites around the Arctic, which has implications for global warming, according to a study by an international group of scientists that included a US team from Baylor University.
A small pilot clinical study at the National Eye Institute (NEI) suggests that the drug nitisinone increases melanin production in some people with oculocutaneous albinism type 1B (OCA-1B), a rare genetic disease that causes pale skin and hair and poor vision. Increased melanin could help protect people with the condition against the sun's UV rays and promote the development of normal vision.
Infants may be more sensitive to non-native speech sounds than previously thought, according to a study published in the Journal of Memory and Language. The findings shed light on the way babies begin to understand language.
Researchers at the Center for Infection and Immunity (CII) at the Columbia University Mailman School of Public Health and the University of New South Wales, Sydney, Australia, provide new evidence supporting an association between elevated levels of enteroviruses in the intestinal tracts of children and islet autoimmunity, a precursor to type 1 diabetes. The paper appears in the journal Scientific Reports.
A major volcanic event could have triggered one of the largest glaciations in Earth's history -- the Gaskiers glaciation, which turned the Earth into a giant snowball approximately 580 million years ago. Researchers from Heidelberg University and colleagues from Mexico have discovered remnants of such a large igneous province that resulted from vast lava flows.
Scientists working in a range of disciplines joined forces to identify a new approach to combat African sleeping sickness. Fundamental research undertaken under the supervision of Professor Ute Hellmich of Johannes Gutenberg University Mainz (JGU) has revealed a promising strategy to develop a suitable agent.
