    Scientists make First Observation of a Polar Cyclone on Uranus

    May 24, 2023, Categories  Astronomy/Space

    NASA scientists used microwave observations to spot the first polar cyclone on Uranus, seen here as a light-colored dot to the right of center in each image of the planet. The images use wavelength bands K, Ka, and Q, from left. To highlight cyclone features, a different color map was used for each.

    Scientists used ground-based telescopes to get unprecedented views, thanks to the giant planet’s position in its long orbit around the sun.

    For the first time, NASA scientists have strong evidence of a polar cyclone on Uranus. By examining radio waves emitted from the ice giant, they detected the phenomenon at the planet’s north pole...

    An international research team led by Professor Long Xiao from the School of Earth Sciences of China University of Geosciences (Wuhan) has discovered the presence of marine sedimentary rocks on the surface of Mars for the first time by comprehensively analyzing the scientific data obtained by the multispectral camera (MSCam) carried by the Zhurong rover...

    Using a new strategy, researchers were able to reduce the challenging MRSA infection in the wounds of diabetic mice by 94%. They were able to completely sterilize the wounds in several of the mice, and the rest had significantly reduced bacterial burden.

    Chronic wounds are open sores or injured tissue that fail to heal properly. These types of wounds are notoriously challenging to treat because of bacterial infections like Staphylococcus aureus, or S. aureus. Additionally, bacterial infections that are highly resistant to antibiotics, such as methicillin-resistant S...

    New technique paves the way for easy oxidation of historically ‘stubborn’ metals. A University of Minnesota Twin Cities-led team has developed a first-of-its-kind, breakthrough method that makes it easier to create high-quality metal oxide thin films out of “stubborn” metals that have historically been difficult to synthesize in an atomically precise manner...
