I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#New way to see RNA could help fight pathogens” Transfer RNA molecules (center) are essential for translating the genetic information in DNA into proteins. New research gives a detailed view of chemical modifications (shown in red) to tRNA that can be important in organisms that cause disease. Credit: Satoshi Kimura In genetics, DNA has always…
“#New synthetic biology tools unlock complex plant engineering” A leaf with various synthetic promoters expressing Green Fluorescent Protein, demonstrating the range of expression levels that can be achieved with their engineered promoters. Credit: JBEI/Berkeley Lab Researchers at JBEI have developed a new set of synthetic biology tools that could unlock advanced plant engineering. The ability…
“#Research reveals more about path bacterial pathogen travels to cause tuberculosis” Jianjun Sun, Ph.D. left, associate professor in The University of Texas at El Paso Department of Biological Sciences, and Javier Aguilera, a doctoral student, stand in Sun’s lab in the Bioscience Research Building. The pair worked with other biology students and faculty members to…
“#Malaria’s secret to surviving in the blood uncovered” Images showing haem crystallisation. The left image shows normal crystallisation and the right shows this in the absence of the PV5 protein. Credit: The Francis Crick Institute New research from the Francis Crick Institute has found how the malaria parasite protects itself from toxic compounds in red…
“#A new antibiotic binding site found in the ribosome” Credit: CC0 Public Domain A group of scientists from Russia, Germany and the United States, led by Skoltech scientists Ilya Osterman, Petr Sergiev, Olga Dontsova and Daniel Wilson from Hamburg University, has studied the mechanism by which tetracenomycin X works, blocking the process of protein synthesis…
“#Designer peptides show potential for blocking viruses, encourage future study” Credit: Rensselaer Polytechnic Institute Chemically engineered peptides, designed and developed by a team of researchers at Rensselaer Polytechnic Institute, could prove valuable in the battle against some of the most persistent human health challenges. The team’s findings, recently published in Nature Scientific Reports, demonstrate how…
“#New compounds from starfish of Kuril basin show efficacy against cancer cells.” Credit: CC0 Public Domain Russian scientists from Far Eastern Federal University (FEFU), G. B. Elyakov Pacific Institute of Bioorganic Chemistry (PIBOC FEB RAS), and A.V. Zhirmunsky National Scientific Center for Marine Biology (NSCMB FEB RAS) have discovered four new steroid substances which target…
“#X-rays size up protein structure at the ‘heart’ of COVID-19 virus” Overlapping X-ray data of the SARS-CoV-2 main protease shows structural differences between the protein at room temperature (orange) and the cryogenically frozen structure (white). Credit: Jill Hemman/ORNL, U.S. Dept. of Energy A team of researchers at the Department of Energy’s Oak Ridge and Argonne…
“#Why are plants green? Research team’s model reproduces photosynthesis” UC Riverside-led research team’s model to explain photosynthesis lays out the next challenging phase of research on how green plants transform light energy into chemical energy. Credit: Gabor lab, UC Riverside. When sunlight shining on a leaf changes rapidly, plants must protect themselves from the ensuing…
“#New approach drives bacteria to produce potential antibiotic, antiparasitic compounds” Researchers used a variety of techniques, including genome mining, to identify bacteria that produce defensive compounds in response to hormone exposure. Their approach will help in the discovery of new antibiotics and other medically useful molecules. Credit: Julie McMahon Researchers have developed a method to…
