                                Some of the dried aloe vera peels utilized in the study

     Although the gel of the aloe vera plant is commonly used to treat sunburn, moisturize skin and boost gut health (among other applications), its peels are typically discarded. New research now suggests that those peels could also be used, to make non-toxic insecticide for use by farmers.

     The study is being led by Asst. Prof. Debasish Bandyopadhyay, of the University of Texas - Rio Grande Valley.

                       Artist's concept of the Lockheed Martin NGI missile

   America's Next Generation Interceptor (NGI) for countering rogue state ICBM attacks has passed a major milestone. Lockheed Martin has announced that the US Missile Defense Agency (MDA) has passed all design elements of the company's NGI missile project.

   Despite the dramatic reduction of the world's nuclear arsenals and launch platforms after the end of the Cold War, there are still an worryingly large number of warheads still poised for launch across the world. With hundreds of missiles aimed at the United States at any moment, the new 21 planned NGIs as part of the nation's Ground Missile Defense (GMD) system seems comically small compared to the threat.

               Against a black background, the gold-foil-covered XRISM spacecraft points directly at the viewer.
  "Viitoarea navă spațială XRISM (X-ray Imaging and Spectroscopy Mission, pronunțat „crism”) va studia cele mai fierbinți regiuni ale universului, cele mai mari structuri și obiecte cu cea mai puternică gravitație. 
   Condus de JAXA (Japan Aerospace Exploration Agency), XRISM va observa aceste extreme cosmice folosind spectroscopie, studiul modului în care lumina și materia interacționează. 
   În acest explicator, producătorul video Sophia Roberts de la Centrul de zbor spațial Goddard al NASA ne prezintă modul în care înțelegerea spectroscopiei ne aprofundează cunoștințele despre univers.

                                            A pellet of LK-99, which was claimed to be the first ever room temperature, ambient pressure superconductor

           Want a flying skateboard? Your own personal home fusion reactor? A wearable MRI scanner you can buy online? If a room-temperature, ambient-pressure superconducting material really has been found, that is just the tip of the technological iceberg.
            Recently, the internet has been abuzz with the news that a new superconducting material called LK-99, which retains its properties at room temperature and ambient atmospheric pressure, may have been developed by a team of researchers at Korea University.

                         FireFly's M100 AV is an autonomous 100-inch robot mower that can handle 5.3 football fields an hour, all by itself

          Grass has got humanity wrapped around its little finger. We carried our favorite grasses with us from the savannahs of Africa as we spread across the world, and even tens of thousands of years later, we're so desperate to be among it that a house doesn't feel like a home for many folk without patches of grass around it.
         Now look, I like a bit of greenery as much as the next fella, but I'm sure I don't have to tell you that grass is a pain in the butt. If you find yourself responsible for some grass, you're required to submit yourself to a fortnightly lawn care ritual, because some neighbors will get real crotchedy if they feel your grass is receiving sub-standard care. No, really, some people get very fired up about this.
