Health Minister Kwon Deok-cheol said Thursday that herd immunity against COVID-19 is expected to be achieved in Korea by November with a public vaccination program set to begin next month. As the first round of inoculation will be completed in September, we expect herd immunity to be formed by November, when 70 percent of the population will have received the vaccine, Kwon said during a virtual New Year press conference, his first press meeting following his inauguration in December.

Trends in Food Science & Technology, the top journal in the food science field with an impact factor of 11.077, Professor Sang-Do Ha from Chung-Ang University, Korea, along with his colleagues, has reviewed the existing literature on biofilm formation and its impact on food industries to identify effective eco-friendly approaches to eradicate unfriendly microbes. Contamination due to biofilms can occur in all types of food raw, minimally processed, fresh, and ready-to-eat, says Prof. Ha. Pathogenic biofilms can accumulate on various food processing machines like milk storage tanks and the conveyer belts of meat-processing plants or on the surface of packaging equipment.

Scientists have known for years that mutations in the MLL4 gene can cause Kabuki syndrome, a rare developmental disorder.
But a study published on Jan. 11 in Nature Communications illuminates new details regarding how this occurs.
The research suggests that MLL4 controls the production of neurons that secrete growth hormone-releasing hormone (GHRH) in a part of the brain called the hypothalamus. Mice without working copies of the MLL4 gene in this area had stunted growth and markedly fewer GHRH neurons. Mice with only one functioning copy of the gene had similar problems.
These are important insights, as GHRH stimulates production of the growth hormone in the pituitary gland in both mice and people. While the effects of Kabuki syndrome vary, delayed growth and short stature are common among patients.
