Dr. Gusarov (Paleoclimatology, Paleoecology and Paleomagnetism Lab) has been working on erosion processes for two decades as a part of various teams. In this research, he tackled the Middle Volga Region, the one where the city of Kazan - and Kazan Federal University - are situated.
The Eastern Pacific Ocean's hurricane season may not officially start until mid-May, but the first tropical cyclone of the season formed over the weekend of April 25 and 26. NASA's Aqua satellite provided an infrared look at the small depression when it was at its peak and before it became post-tropical.
Pasadena, CA-- The universe is full of billions of galaxies--but their distribution across space is far from uniform. Why do we see so much structure in the universe today and how did it all form and grow?
A 10-year survey of tens of thousands of galaxies made using the Magellan Baade Telescope at Carnegie's Las Campanas Observatory in Chile provided a new approach to answering this fundamental mystery. The results, led by Carnegie's Daniel Kelson, are published in Monthly Notices of the Royal Astronomical Society.
Last summer, a new age for high-temperature superconductivity was proclaimed - the nickel age. It was discovered that there are promising superconductors in a special class of materials, the so-called nickelates, which can conduct electric current without any resistance even at high temperatures.
CORVALLIS, Ore. - An international research collaboration has taken an important step toward the commercially viable manufacture of biobutanol, an alcohol whose strong potential as a fuel for gasoline-powered engines could pave the path away from fossil fuels.
The key breakthrough is the development of a new metal organic framework, or MOF, that can efficiently separate biobutanol from the broth of fermented biomass needed for the fuel's production. Findings were published today in the Journal of the American Chemical Society.
Atmospheric contamination is one of society's main concerns, with nitrogen dioxide (NO2) and tropospheric ozone (O3) being among the contaminants that are giving rise to the most concern. In principle, the measures to reduce NO2 contamination effectively are fairly easy to identify; however, reducing O3 contamination is much more complex because it is a secondary contaminant that is not emitted directly but is generated on the basis of chemical reactions in the atmosphere.
HOUSTON - (April 27, 2020) - Delivering water to city dwellers can become far more efficient, according to Rice University researchers who say it should involve a healthy level of recycled wastewater.
Using Houston as a model, researchers at Rice's Brown School of Engineering have developed a plan that could reduce the need for surface water (from rivers, reservoirs or wells) by 28% by recycling wastewater to make it drinkable once again.
A UCLA-led research team today reports that it has developed a new method for delivering DNA into stem cells and immune cells safely, rapidly and economically. The method, described in the journal Proceedings of the National Academy of Sciences, could give scientists a new tool for manufacturing gene therapies for people with cancer, genetic disorders and blood diseases.
Diagnosing emphysema and classifying its severity have long been more art than science.
"Everybody has a different trigger threshold for what they would call normal and what they would call disease," said U. Joseph Schoepf, M.D., director of cardiovascular imaging for MUSC Health and assistant dean for clinical research in the Medical University of South Carolina College of Medicine. And until recently, scans of damaged lungs have been a moot point, he said.
In what is believed to be a first-of-its-kind study to evaluate the safety of a type of immunotherapy before surgery in patients with an aggressive form of skin cancer, researchers report that the treatment eliminated pathologic evidence of cancer in nearly half of the study participants undergoing surgery. In patients whose tumors respond, this treatment approach offers the potential to reduce the extent of surgery and may also slow or eliminate tumor relapses that often occur after surgery.
Bethesda, MD - Researchers have used threads made of engineered human tissue to weave blood vessels that could one day help repair diseased or damaged blood vessels.
"Blood vessels are just one example of what can be done with our new textile approach to tissue engineering," said research team leader Nicolas L'Heureux, PhD, director of research at Inserm/University of Bordeaux in France. "It can be used to make practically any shape by weaving, braiding or knitting the threads and allows very good control of the mechanical properties of the final product."
Bethesda, MD - Although today's rheumatoid arthritis treatments can reduce symptoms, they often come with serious side effects. Results from a new mouse study suggest that a new light-activated drug delivery method helps confine treatments to the joints, which could reduce whole-body side effects.
In the U.S., 1.3 million people are currently diagnosed with rheumatoid arthritis, a chronic disease that causes painful joint swelling that can eventually lead to bone loss and joint deformities.
Bethesda, MD - Whether it is loud machinery at work, a busy freeway or a nearby airport, many people are exposed to high levels of noise. Two new mouse studies provide new insight into how this type of noise exposure can lead to high blood pressure and cancer-related DNA damage.
Bethesda, MD - A new study has shown that salt-tolerant bacteria can be used to enhance salt tolerance in various types of plants. The new approach could increase crop yield in areas dealing with increasing soil salinity.
Each year, about 2 million to 3 million hectares of irrigated farmland go out of production worldwide due to salinity problems, according to the U.S. Agency for International Development. Increased soil salinity not only reduces water uptake for crops but can often create a nutrient imbalance that decreases plant growth and yield.
Bethesda, MD - People who suffer frequent indigestion may find relief with a small device that hooks onto the ear known as a transcutaneous auricular vagus nerve stimulator, or taVNS. People who used taVNS showed significant improvements in their stomach's ability to accommodate and process a meal, according to a new study.
