Answer: Understanding food labels can go a long way in managing your diet. The Food and Drug Administration (FDA) Nutritional Facts labels were updated in 2020 to help people better recognize healthier choices.
The FDA required manufacturers with $10 million or more in annual sales to update their labels by Jan. 1, 2020, and those manufacturers with less than $10 million in annual food sales to update their labels by Jan. 21, 2021. Companies that produce single-ingredient sugars, such as honey and maple syrup and some cranberry products have until July 1, 2021, to make changes.
Scientific studies from the National Academies of Science, Engineering, and Medicine, formerly known as the Institute of Medicine, played a big role in the label changes. Some vitamin information, such as vitamin D and potassium, were added because studies found Americans tend to be deficient in those nutrients. âAdded sugarsâ is a new entry because these food choices increase the risk o

Researchers call for greater awareness of unintended consequences of CRISPR gene editing
CRISPR-Cas9 genome editing can lead to unintended mutations at the targeted section of DNA in early human embryos, researchers have revealed. This highlights the need for further research into the effects of CRISPR-Cas9 genome editing, especially when used to edit human DNA in laboratory research.
We and others are trying to develop and refine the tools to assess these complex mutations. Kathy Niakan
CRISPR-Cas9 genome editing is a widely used research tool which allows scientists to remove and replace sections of DNA in cells, allowing them, for example, to study the function of a given gene or to repair mutations. Last year the researchers who developed CRISPR-Cas9 were awarded the Nobel Prize in Chemistry.

Groundbreaking research from Tel Aviv University may lead to a significant breakthrough in the battle against deadly brain cancer. To begin with, the researchers identified a failure in the brain s immune system, leading to the amplification of cell division and spread of Glioblastoma cancer cells. The failure results partially from the secretion of a protein called P-Selectin (SELP), which, when bound to its receptor on the brain immune cells, alters their function so that instead of inhibiting the spread of cancer cells, they do the opposite, enabling them to proliferate and penetrate brain tissues.
At the next stage of the study, the researchers were able to inhibit the secretion of the SELP protein, thereby neutralizing the failure in the immune system, restoring its normal activity, and blocking the spread of this incurable cancer. The international research team was led by Prof. Ronit Satchi-Fainaro, Director of the Cancer Biology Research Center a

NORMAN â The arrival of spring means an increase in sneezing, congestion and scratchy throats for many Oklahoma City metro residents due to allergies.
A recent report from the Asthma and Allergy Foundation of America reveals the Oklahoma City metro area ranks as the ninth most challenging city to live in for allergy sufferers. The rankings are based on data from the 100 most populated Metropolitan Statistical Areas in the contiguous 48 states, and factor in pollination scores, rate of over-the-counter antihistamine use and number of allergy specialists in the
