[ad_1] Identifying and isolating people who may be contagious with the coronavirus is key to limiting the spread of the disease. But even months into the pandemic, many patients are still waiting days to receive COVID-19 test results. Scientists from UC Berkeley and the Gladstone Institutes have developed a new …

[ad_1] Photo: Juan Mabromata (Getty Images) In a new letter to the editor taken from the prestigious scientific journal Nature, a team of Israeli researchers asks a frankly absurd question: Could a computer hack lead a scientist to be tricked into creating a piece of genetic code that is harmful …

[ad_1] Antibiotics are used to prevent and treat bacterial infections. They have played an important role in the fight against infectious diseases such as tuberculosis, pneumonia, typhoid fever and meningitis in 20th century. However, the misuse of antibiotics has also led to the development of so-called multi-drug resistance (MDR) whereby …

[ad_1] November 27, 2020 New research suggests that a blood test to look at the “molecular clock” of breast cancer could help monitor the growth of multiple cancers throughout the body and monitor their response to treatment. The test, developed by British scientists, could help identify more actively growing cancers …

[ad_1] New research has identified and described a cellular process that, despite what the textbooks say, has remained elusive to scientists until now – precisely as the copy of genetic material that, once initiated, is properly deactivated. The discovery concerns a key process essential to life: the transcription stage of …

[ad_1] Scientists from EPFL and the Friedrich Miescher Institute used cryo-electron microscopy to explain how a DNA-sensitive biomolecule that is key to our innate immune response is inactivated when it comes into contact with the cell’s DNA. One biomolecule that has garnered considerable attention in recent years is cGAS, a …

[ad_1] Reviewed by Emily Henderson, B.Sc.November 25, 2020 NASA’s historic twin study studied identical twin astronauts Scott and Mark Kelly and provided new insight into the health effects of spending time in space. Professor Susan Bailey of Colorado State University was one of more than 80 scientists from 12 universities …

[ad_1] Reviewed by Emily Henderson, B.Sc.November 25, 2020 With new insights into how the CRISPR genetic tool – which allows direct editing of our genes – has evolved and adapted, we are now one step closer to understanding the basics of the constant struggle for survival that takes place in …

[ad_1] In a recent medRxiv * preprint paper, the researchers of the Health Center of the University of Connecticut in the United States reveal their method CRISPR (WS-CRISPR) with digital hot start for rigorous quantitative and sensitive detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV -2) in clinical samples …

[ad_1] November 23, 2020 – Researchers say they used CRISPR, a new technology that allows scientists to modify a cell’s DNA, to destroy cancer cells in mice. The first research conducted on two types of metastatic cancer – ovarian cancer and brain cancer – have not been tested in humans. …
