After billions of people worldwide were vaccinated, scientists turned their attention to the COVID-19 drug, which, together with the vaccine, could be effective in combating the virus. US-based biopharmaceutical company Gilead Sciences Inc announced that Remdesivir has a great effect against COVID-19 as a result of its extensive research on this subject.
Research continues to end COVID-19, which has been affecting our lives for about a year and a half and has claimed 4.55 million lives to date. After billions of doses of vaccine were distributed all over the world, scientists started working on COVID-19 drugs, which they said would provide high protection against the virus when combined with the vaccine.
Remdesivir was one of the most talked about drugs both in our country and all over the world. Remdesivir, which is the only drug approved for use in the treatment of COVID-19 by the American Food and Drug Administration (FDA), provides great protection against COVID-19, according to research by the American-based biopharmaceutical company.
Remdesivir significantly reduces the rate of intensive care admissions. President of the US National Institute of Allergy and Infectious Diseases, Dr. Anthony Fauci previously commented on Remdesivir and stated that the drug has a clear cure in the treatment of COVID-19; “The data show that Remdesiviri has a clear, significant and positive effect on recovery time.” Fauci’s words were proven months later, and Gilead Sciences Inc announced that Remdesivir was effective against COVID-19 on both early and advanced patients. According to the statements made, Remdesivir reduces the rate of intensive care hospitalization due to COVID-19 by 87%. The drug works well in patients with severe infections, but is also effective in patients in whom the infection has not yet spread much in the early period.
scientists working at Purdue University; after seven years of work, they succeeded in developing the ‘world’s whitest paint’, which helps combat global warming. It was reported that the paint keeps the environment it is in even cooler than an air conditioner. Scientists working at Purdue University in Indiana, USA; announced that they have developed the world’s whitest paint ever to combat global warming. It has been noted that the world’s whitest paint reflects 98.1% of sunlight, cooling the environment it is in even more than an air conditioner. Developed to reduce global warming:
The white paint developed by Xiulin Ruan, a professor of mechanical engineering at Purdue University, and her students has entered the Guinnes Book of World Records as the owner of the title of ‘the whitest paint ever made’. Stating that the paint was developed by him and his team with the aim of ‘helping to reduce global warming’, Professor Ruan said that the paint that helps energy saving and climate change was obtained as a result of a seven-year study process.
The paint, which was developed in the university laboratory and was first born from the idea of repelling sunlight from a building; It was stated that a surface coated with this paint cools below the ambient temperature without consuming power, since it reflects 98.1% of sunlight and emits infrared heat and absorbs less solar heat. At the end of the research, it was discovered that the white paint used to completely paint a roof surface of approximately 92 square meters can provide a cooling power of 10 kilowatts. “This is more powerful than most home air conditioners,” said Professor Ruan.
An ordinary white paint, far from cooling the environment, actually makes it much warmer. It is known that 80 to 90% of the paints on the market reflect sunlight, while at the same time causing the surface to heat up more.
The scientists behind the study; He says there are two main reasons why the paint is “the whitest paint in the world”. The first of these two reasons is that a very high concentration of barium sulfate, a chemical substance used in paint, photographic paper and cosmetics, is used. The second reason is the presence of different particle sizes of barium sulfate in the paint. Thanks to the wider size range, the light from the sun allows the spectrum to spread even more.
