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.
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.
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.
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.
