I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Cell competition in the thymus is crucial in a healthy organism” Credit: CC0 Public Domain T lymphocyte cells develop in the thymus. They are essential for fighting infections and preventing cancer. The thymus is located just above the heart. It is large in children and gradually reduces in size with age. In the thymus, T…
“#’Good’ virus for common infection” Credit: CC0 Public Domain Australian researchers have shown how viruses can be used to save lives, developing the potential use of bacteriophages in bandages to treat life-threatening golden staph infections which may not respond to traditional antibiotics. Targeting multidrug-resistant Staphylococcus aureus (‘golden staph’) in diabetic foot ulcers, Flinders University microbiology…
“#Epigenetics and cell diversity in the embryo” After 8 days, the developing mouse embryo resembles a seahorse. Without the epigenetic regulator PRC2, it is less complex and looks more like an egg. A closer look into the cells of the embryo reveals the tasks of regulatory factors during development. Credit: Abhishek Sampath Kumar / MPIMG…
“#Close relatives of the novel coronavirus may have circulated in bats for decades before jumping to humans” Credit: CC0 Public Domain Close relatives of the virus behind COVID-19 likely circulated in bats for decades before the viruses made their jump into humans last yeaafix r, igniting the worst global pandemic in more than 100 years,…
“#Researchers identify evolutionary origins of SARS-CoV-2” Credit: Pixabay/CC0 Public Domain By reconstructing the evolutionary history of SARS-CoV-2, the virus that is responsible for the COVID-19 pandemic, an international research team of Chinese, European, and U.S. scientists has discovered that the lineage that gave rise to the virus has been circulating in bats for decades and…
“#Not just light: The sensitivity of photoreceptors to mechanical stimuli is unveiled” Credit: International School of Advanced Studies (SISSA) Thanks to optical tweezers, a new study reveals unexpected properties of the neurons responsible for the transduction of light signals. The research has been published in PLOS Biology. “We thought we knew almost everything about photoreceptors,…
“#Life in the pits: Scientists identify the key enzyme behind body odor” Credit: Pixabay/CC0 Public Domain Scientists have discovered a unique enzyme responsible for the pungent characteristic smell we call body odor or BO. Researchers from the University of York have previously shown that only a few bacteria in your armpit are the real culprits…
“#Genetic mutations help super bug become highly resistant to antibiotics” A colorized scanning electron micrograph of MRSA. Credit: National Institute of Allergy and Infectious Diseases Scientists from the University of Sheffield have found that genetic mutations in MRSA allow it to evolve and become more resistant to antibiotics such as penicillin. The research, published in…
“#Scientists discover key to restricting antibiotic resistant bacteria” Credit: CC0 Public Domain Antibiotic resistance poses a significant threat to human health on a global scale. It has been predicted that resistant infections will cause 10 million deaths per year by 2050. Given that antibiotics are crucial in many areas of medicine, it is important to…
“#Scientists use CRISPR technology to insert sex-determining gene” Credit: UC Davis Scientists at the University of California, Davis, have successfully produced a bull calf, named Cosmo, who was genome-edited as an embryo so that he’ll produce more male offspring. The research was presented in a poster on July 23 at the American Society of Animal…
