Researchers have developed a new method called the Walker Diffusion Method (WDM) that accurately models fluid transport in porous materials. This approach uses simple probabilistic rules to calculate the movement of 'random walkers' through the material, revealing the overall physical structure and flow paths.
Researchers have identified aquaporin-1 protein's role in regulating water movement into and out of cells, a fundamental requirement for life. In a study comparing normal lungs to those without the protein, scientists found increased airway wall thickness and fluid leakage in those with aquaporin-1.
PNNL researchers developed an ultrasonic tool to monitor key physical properties of fluid products in real-time. Additionally, the lab showcased a new mass spectrometry technique called DREAMS that analyzes more proteins with greater accuracy, providing insights into low-level proteins crucial for cellular processes.
A University of Houston researcher developed a biodegradation test to ensure synthetic-based drilling fluids are environmentally safe. The EPA guideline reduces pollution by seven million pounds annually, saving operating costs without economic impacts.
A new non-invasive technique using modified breast pumps to collect breast fluid samples shows promise in predicting breast cancer risk. Women with normal cells in their fluid are 30% more likely to develop cancer, while those with abnormal cells are twice as likely.
Researchers at the University of Illinois discovered that estrogen regulates fluid reabsorption in the male reproductive tract by triggering a protein involved in sodium transport. This finding suggests that blocking estrogen receptors could provide a new target for developing effective contraceptives for men.
Researchers at UNC developed a technique to deliver oxygen-carrying fluid to resuscitate the heart after cardiac arrest. The method, selective aortic arch perfusion (SAAP), has shown promising results in animal studies and may help save trauma victims by allowing surgeons to repair damage.
Researchers are using a technique called fluid inclusion micro thermometry to determine the formation temperature of quartz cement in 300-million-year-old sandstones. The study aims to understand the thermal history of these ancient rocks and its implications for understanding oil and gas formation.
Two Dartmouth researchers, Erland Schulson and Carl Renshaw, propose a theory that brittle materials like rocks and ice crack in the same manner. They identify a specific type of cracking mechanism, 'comb' cracks, which leads to collapse in both ice and rock.
Researchers at the University of Illinois discovered that fluids with high enough speed can slip over smooth solid surfaces, unlike textbook predictions. This phenomenon has significant implications for applications such as microfluidic devices and lubrication in computer hard drives.
A research team led by University of Colorado at Boulder Professor Roger Bilham failed to find alternatives to huge Indian earthquakes, concluding that at least one 8.1-8.3 magnitude earthquake and up to seven are overdue due to the movement of the Indian plate towards Tibet.
Scientists at the University of Illinois have devised a process called nanoparticle haloing that imparts stability to complex fluids, enabling control over phase behavior and structure. This approach allows for the creation of designer colloidal fluids with tailored properties.
Researchers find unique vent systems on seafloor mountain Atlantis Massif, formed by heat generated when seawater reacts with mantle rocks. The Lost City Field may be common, potentially upending previous estimates of hydrothermal venting and life on the seafloor.
Researchers at Vanderbilt University Medical Center are performing the first amniotic exchange procedure in the US to treat gastroschisis. The procedure involves removing caustic amniotic fluid and replacing it with sterile saline solution to improve fetal outcomes.
A small earthquake off Washington's coast caused hydrothermal vent systems miles away to pump out warmer water in an unexpected pulsing pattern. This has led scientists to re-evaluate their understanding of fluid flow within oceanic crust, which had previously been assumed to be stable and relatively unchanging.
Virginia Tech researchers have made advances in creating biocompatible magnetic fluids to treat retinal detachment. The new material, made of silicone magnetic nanoparticles, can be injected into the sclera and used with a magnetized buckle to push the retina back against the underlying choroid.
A new study suggests that proteins alphav-beta3 and leukemia inhibitory factor (LIF) may serve as biomarkers for identifying women with endometriosis-related infertility. The research found a marked reduction in embryo implantation in mice injected with peritoneal fluid from infertile women with endometriosis.
A study found that 24% of elderly individuals experienced recurring dizziness, with factors like anxiety, depression, and taking five or more medications contributing to the issue. Two last-resort options for end-of-life suffering are discussed: terminal sedation and voluntary refusal of food and fluids.
Researchers at the University of Rochester have adopted Belarusian-developed magnetorheological finishing (MRF) technology to polish high-precision optics, including camcorders, CD players, and telescopes. The process uses a unique slurry that changes viscosity in response to magnetic fields.
A study by Cedars-Sinai Medical Center has detected and measured contaminants from certain pesticides and industrial chemicals in the amniotic fluid of unborn babies. DDE levels were found in 30% of the population, ranging from 0.1 to 0.63 nanograms per milliliter, which is comparable to natural hormone levels.
Researchers at Stanford University used optical tweezers to study the microscopic properties of magnetorheological fluids, finding that they behave in unexpected ways. The materials can form long chains and exhibit lateral aggregation, leading to a greater-than-expected range of behavior with varying magnetic field strengths.
Engineers have developed a method for coating threads with size using supercritical fluids, reducing chemical and water waste in the textile industry. The new technique could speed up thread processing by a factor of ten and replace centuries-old technology.
The Gallup survey reveals that 77% of American moms whose preschool children have suffered from ear infections are concerned about the long-term effects. Despite this, many parents are unaware of how to detect middle ear fluid, which can cause complications such as hearing loss and speech delays.
Researchers found high concentrations of tolyltriazoles in groundwater under an airport, causing toxicity to bacteria and aquatic life. Current regulations only monitor glycol levels, ignoring major sources of toxicity.
Dr. Daniel B. Lee's research suggests that rituals, not common beliefs, provide social glue for religious communities. This is evident in the Weaverland Mennonites' case study, where symbols and rituals sustain unity despite individual members having fluid and unstructured religious beliefs.
Researchers discovered ehrlichiosis, a tick-borne infection, shows increased fluid in lungs on chest X-rays, helping doctors diagnose it earlier and potentially treat it more effectively. The illness can be mild but also rapidly fatal, and early detection is crucial.
A shellfish toxin study has discovered a mechanism that may help treat cystic fibrosis by stimulating fluid flow through protein phosphatase inhibition. This could lead to loosening of accumulated mucus in the lungs and gut, reducing bacterial infections and early death.
A study by Pat Rusin and her colleagues at the University of Arizona found that toilet seats were consistently cleaner than kitchen surfaces, including sinks, tap handles, and chopping boards. The researchers believe this is due to the dry environment of toilet seats, which are less conducive to bacterial growth.
Researchers found that mating is more harmful to females than egg laying, with costs imposed by males leading to female survival and reproductive value depression. In contrast, egg production has a minimal impact on female fitness under certain conditions.
A new process using ultraviolet light has been developed to treat opaque industrial fluids, eliminating the need for chemical biocides and reducing waste volumes. The technology also shows promise in decontaminating drinking water, wastewater, and ballast water from commercial ships.
