Coronavirus (COVID-19) Update: FDA Authorizes First Antigen Test to Help in the Rapid Detection of the Virus that Causes COVID-19 in Patients

May 10, 2020 |

Silver Spring, MD – The U.S. Food and Drug Administration (FDA) has issued the first emergency use authorization (EUA) for a COVID-19 antigen test, a new category of tests for use in the ongoing pandemic. These diagnostic tests quickly detect fragments of proteins found on or within the virus by testing samples collected from the nasal cavity using swabs.

NASA research shows Sugar Molecule may exist in Interstellar Space

December 29, 2018 |

NASA’s Ames Research Center

Mountain View, CA – When we think of sugar, it’s in the form of a holiday sweet or a reason to head back to gym after New Year’s Eve — we don’t usually think of the complex varieties that form the structural backbones of our very genetic code. And we certainly don’t think of sugar floating around in the vast darkness of space.

New research suggests that the sugar molecule that puts the “D” in DNA — 2-deoxyribose — could exist in the far reaches of space. A team of NASA astrophysicists were able to create DNA’s sugar in laboratory conditions that mimic interstellar space.

NASA researches develop Chemical Laptop that could look for life on other Planets

Pasadena, CA – If you were looking for the signatures of life on another world, you would want to take something small and portable with you. That’s the philosophy behind the “Chemical Laptop” being developed at NASA’s Jet Propulsion Laboratory in Pasadena, California: a miniaturized laboratory that analyzes samples for materials associated with life.

“If this instrument were to be sent to space, it would be the most sensitive device of its kind to leave Earth, and the first to be able to look for both amino acids and fatty acids,” said Jessica Creamer, a NASA postdoctoral fellow based at JPL.

Researchers took the Chemical Laptop to JPL’s Mars Yard, where they placed the device on a test rover. This image shows the size comparison between the Chemical Laptop and a regular laptop. (NASA/JPL-Caltech)

NASA scientists use new Technique to examine meteor, comet materials for components of Life

Greenbelt, MD – While the origin of life remains mysterious, scientists are finding more and more evidence that material created in space and delivered to Earth by comet and meteor impacts could have given a boost to the start of life.

Some meteorites supply molecules that can be used as building blocks to make certain kinds of larger molecules that are critical for life.

Researchers have analyzed carbon-rich meteorites (carbonaceous chondrites) and found amino acids, which are used to make proteins.

FDA defines “Gluten-Free” for Food Labeling

August 5, 2013 |

Washington, D.C. – Celiac disease is a serious health issue that can lead to critical complications if not treated.

While there is no cure for celiac disease (CD), there is one way to manage it – following a gluten-free diet. The only choice for the up to three million Americans living with CD is to adhere strictly to a gluten-free diet, avoiding proteins that occur naturally in wheat, rye, barley and cross-bred hybrids of these grains.

Gluten-Free Labeling Consumers Can Count On

New Tactic for Controlling Blood Sugar in Diabetes Contradicts Current View of the Disease

September 4, 2011 |

Study finds inflammation may be part of the solution, not the problem

Boston, MA – Increased low-grade inflammation in the body resulting from obesity is widely viewed as contributing to type 2 diabetes. Going against this long-held belief, researchers from Children’s Hospital Boston report that two proteins activated by inflammation are actually crucial for maintaining good blood sugar levels – and that boosting the activity of these proteins can normalize blood sugar in severely obese and diabetic mice.

The research, led by Umut Ozcan, MD, in the Division of Endocrinology at Children’s, is reported in the October issue of Nature Medicine, published online September 4th. «Read the rest of this article»
