Over the past three decades Ara Mirzaian has fitted braces for everyone from Paralympians to children with scoliosis. But Msituni was a patient like none other—a newborn giraffe.
Lei Zhang, Ph.D., and Michael Niederweis, Ph.D., of the University of Alabama at Birmingham have made what they call "a major step" in understanding how Mycobacterium tuberculosis acquires iron from its human host—a process essential for the pathogenesis of this bacterium. Tuberculosis kills more than 1 million people each year, but without iron, M. tuberculosis cannot grow.
Researchers at Eötvös Loránd University (ELTE) have created a new disease model that has contributed to a better understanding of Bloom syndrome and the sex determination processes of zebrafish. The study, linking two seemingly unrelated topics, was carried out by the research teams of Mihály Kovács (Department of Biochemistry) and Máté Varga (Department of Genetics) and published in the...
A relentless heat wave has blanketed India and Pakistan since mid-March, causing dozens of deaths, fires, increased air pollution, and reduced crop yields. Weather forecasts show no prospect of relief any time soon. NASA's Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station instrument (ECOSTRESS) has been measuring these temperatures from space, at the highest spatial resolution of...
GREMM director Robert Michaud said it is difficult to determine the reasons why a minke whale would venture so far from its usual habitat, which is some 450 kilometres down river in the Gulf of St. Lawrence and...
Researchers had no idea if anything would sprout in harsh moon dirt and wanted to see if it could be used to grow food by the next generation of lunar explorers. The results stunned...
NASA's Hubble Space Telescope has allowed astronomers to view galaxies of all shapes and sizes from nearly every angle. When a galaxy is seen edge-on, the mesmerizing perspective reveals a dazzling slice of the universe. The "Little Sombrero," also known as NGC 7814 or Caldwell 43, is one such galaxy.
A Colorado State University-led study published in the journal Environmental Science & Technology reveals that in U.S. cities over a several-year period, natural gas pipeline leaks were more prevalent in neighborhoods with low-income or majority non-white populations than those with high income or predominately white populations.
At just 33 years old, Caltech assistant professor Katie Bouman is already a veteran of two major scientific discoveries.
The vibrational modes of nanomechanical resonators are analogous to different notes of a guitar string and have similar properties such as frequency (pitch) and lifetime. The lifetime is characterized by the quality factor, which is the number of times that the resonator oscillates until its energy is reduced by 70%. The quality factor is crucial for the modern applications of mechanical...
Earth's oceans are home to some of the most diverse ecosystems on the planet, but warming temperatures are causing many marine animals, including coral, to die out.
A new study reveals that in U.S. cities over a several-year period, natural gas pipeline leaks were more prevalent in neighborhoods with low-income or majority non-white populations than those with high income or predominately white populations.
The declining body size of North Atlantic right whales may have critical consequences for the future of the species. New research shows that smaller females produce fewer calves.
The Human Cell Atlas sheds new light on the types and traits of immune cells that can be found in the human body, from developmental stages to adulthood.
Research could provide a new approach to treating an aggressive form of breast cancer. A study found that targeting the immune microenvironment in lymph nodes and tumors simultaneously led to long-term tumor remission in mice models of metastatic triple negative breast cancer.
The massive Jan. 15, 2022, eruption of the Hunga submarine volcano in the South Pacific Ocean created a variety of atmospheric wave types, including booms heard 6,200 miles away in Alaska. It also created an atmospheric pulse that caused an unusual tsunami-like disturbance that arrived at Pacific shores sooner than the actual tsunami.
A study investigates the reasons for decreasing remission rates for patients with non-Hodgkin lymphoma treated with chimeric antigen receptor-T cell therapy (CAR-T cell therapy).
Scientists found a chemical from a rainforest tree that binds to opioid receptors in the brain and may have utility as an antidepressant or anti-anxiety drug.
Optical computing uses photons instead of electrons to perform computations, which can significantly increase the speed and energy efficiency of computations by overcoming the inherent limitations of electrons. The basic principle of optical computing is the light-matter interaction. Matrix computing has become one of the most widely used and indispensable information processing tools in science...
Water often falls from the sky and is stored in mountains across the U.S. as snow before it melts and flows down to urban and rural communities. Knowing what factors influence when and how much of that snowmelt ultimately makes it to streams, rivers and reservoirs is crucial for water managers trying to make the most of limited water resources. A new study led by researchers at University of...
People are more likely to choose a healthy food option than an unhealthy food option among people from different social groups because they fear being judged negatively for their choices.
