If you look up at the stars at night, then you might think the stars flicker, blink, wink, or twinkle. You might ask yourself, “why do the stars appear to twinkle?” While you may think that the stars are twinkling, they are shining steadily. They only appear to twinkle because of the interaction between your eyes, the starlight, and the Earth’s atmosphere. The Earth’s atmosphere is made up of different levels of temperatures and densities. In addition to the temperature and density differences, there is a lot of wind in the atmosphere. When the star’s light enters the Earth’s atmosphere, it must pass through these layers of temperature differences, density differences, and wind. Moving air in the atmosphere can be called turbulence. The star’s light must enter our atmosphere, but the star’s light does not necessarily move in a straight line through the atmosphere. Instead, the starlight is refracted or is spread around in different directions in the atmosphere. The starligh...

Some medicine that we are using are having photosynthesis property it's means it ready to photo chemical reaction. Something this will be lost it it's physical and chemical properties if any light exposed to on it. For example if that a medicine having 2 years of expiry period, that becomes expired with in 4 hours due to the light exposed to the medicine . If we use it, we will get allergies and side effects .Due to this light energy exposed to the drug it become failures it's called photo degradation. Commonly the ULTRAVIOLET RAYS (UV) have high penetration power. if it exposed to a medicine, that will be losses it's chemical and physical properties. For an example, take an transferable glass bottle which is filled up with photo synthesis medicine. Here the light energy penetrate the medicine so it become changes its physical and chemical properties. Every colour have an frequency including the brownish. This amper colour will hav...

Magnetic resonance imaging (MRI) can provide an effective way of supporting the development of the next generation of high-performance rechargeable batteries, according to research led by the University of Birmingham. The technique, which was developed to detect the movement and deposition of sodium metal ions within a sodium battery, will enable faster evaluation of new battery materials, and help to accelerate this type of battery's route to market. Sodium batteries are widely recognised as a promising candidate to replace lithium ion batteries, currently widely used in devices such as portable electronics and electric vehicles. Several of the materials required to produce lithium ion batteries are critical or strategic elements and, therefore, researchers are working to develop alternative and more sustainable technologies. Although sodium appears to have many of the properties required to produce an efficient battery, there are challenges in optimising th...

Development of a new ventilator prototype for the ICU against COVID-19. Credit: UC3M Researchers and technicians from the  Universidad Carlos III de Madrid (UC3M) and the University Hospital Gregorio Marañón (HGUGM)  have designed and developed a new ventilator prototype for Intensive Care Units (ICU) in the fight against the health crisis caused by COVID-19. The assembly of two units has just been completed in order to start animal tests and homologation processes. These ventilators are an indispensable element for patients in intensive care with severe respiratory distress, for whom the mechanical ventilators being developed through other initiatives are not suitable. The project to support the development and manufacturing of these ventilators, which began on 1st April with a crowdfunding campaign organised by the Universidad Carlos III Foundation, achieved its initial funding target (50,000 Euros) in just 24 hours. With this funding, the prototype's creation and testi...
