(Latvijas Televīzija) Scientists of Rīga Technical University (RTU) work on new biofuel synthesis techniques, which could open up the possibility of producing such fuel in Latvia, Latvian Television reported February 16.
With global warming and climate change, the world is increasingly thinking of abandoning the use of diesel and petrol in the operation of vehicles.
There are two ways of doing that now: driving an electric car, which not everyone can afford at the moment, or developing the production of biofuels based on renewable resources.
Currently, in many parts of the world, oil of various plants is used for the development of such biofuels, but according to Valdis Kampars, director of the RTU Institute for Applied Chemistry, it shouldn t be done too much with materials that can be used for consumption:

I am a geologist who studies landscapes their forms and the processes that shape them. I grew up in Neosho, MO, and attended Colorado College, earning a bachelor’s in Geology. I also attended Colorado School of Mines for a master’s in Environmental Science and Engineering. Finally, I graduated from the University of Wyoming with a Ph.D. in Geology. My husband and I have two children, both will be freshman in the fall 2021. My son will be attending Colorado College, and my daughter will be a freshman at Little Rock Central High School. My hobbies are mostly outdoor related. I love to hike, camp, ride my bike, and travel.

L’Oréal-UNESCO For Women in Science Awards honour five women researchers in mathematics, astrophysics
On the International Day for Women and Girls in Science, celebrated on 11 February, UNESCO and the L’Oréal Foundation honoured five women researchers in the fields of astrophysics, mathematics, chemistry and informatics as part of the 23rd International Prize for Women in Science.
On this occasion, UNESCO published a global study on gender equality in scientific research. Entitled To be smart, the digital revolution will need to be inclusive, it shows that although the number of women in scientific research has risen to one in three, women remain a minority in mathematics, computer science, engineering and artificial intelligence. Every year, women write as many scientific articles as men, but their chances of appearing in prestigious journals are lower. While women represent 33% of researchers, on average they only occupy 12% of seats on national science academies
CUSAT find ways to recycle used medical masks as engineering products

Plastic fibres separated from the used medical face masks could be blended with rubber to make polymer compounds and manufacture engineering products. Disposal of face masks in these pandemic times has turned out to be a challenge for many. The researchers at Cochin University of Science and Technology (CUSAT) have developed an innovative method to recycle these used medical face masks as engineering products.
Prasanth Raghavan and P. M. Sabura Begum faculties at CUSAT, who jointly guided the research, said that the plastic fibres separated from the used medical face masks collected from various sources could be chopped and blended with rubber to make polymer blends with high tensile strength, impact strength and thermal properties. This can be used to manufacture high-performance engineering products such as car bumpers, dashboards, fighter jets and submarines as protective shielding
Prevention is the most cost-effective and long-term strategy for controlling this disease. It is now well known that almost 50% of all malignant tumors can be prevented with proper nutrition based on natural products with a preventive effect. Polyphenols are the largest variety of plant components. It is this class of chemical compounds that have shown powerful antioxidant properties. They actively fight against cellular damage caused by free radicals, slowing down the aging and preventing oxidation. In addition, they protect the body from inflammatory, cardiovascular, neurodegenerative diseases, and some forms of cancer , one of the authors of this study, associate professor of the Department of Technology and Organization of Public Catering of Samara Polytech Natalya Eremeeva explains. We studied in detail the beneficial properties of lingonberry, raspberry, black chokeberry, grapes, Krasnodar green tea, ginseng, fireweed and coffee.
