Widespread Use of Potentially Harmful PFAS Found in Cosmetics
Many cosmetics sold in the United States and Canada likely contain high levels of per- and polyfluoroalkyl substances (PFAS), a potentially toxic class of chemicals linked to a number of serious health conditions, according to new research.
Immune Protein May Protect Premature Babies From Deadly Intestinal Disease
Researchers have identified a protein in the immune system that may protect babies from necrotizing enterocolitis and lead to the development of new treatments.
Metabolic Processes Visualized at the Single-Cell Level
Researchers at the University of Chicago's Pritzker School of Molecular Engineering and Biological Sciences Division have developed a combined imaging and machine learning technique that can, for the first time, measure a metabolic process at both the cellular and sub-cellular levels.
Landfill Bacteria Could Help To Eliminate Toxic Chemicals
Researchers have used landfill bacteria to generate enzymes that can break down dangerous such as pesticides and brominated flame retardants, that accumulate in nature and in food chains.
Infant Immune System Trained by Key Gut Bacteria
Many diseases caused by a dysregulated immune system, such as allergies, asthma and autoimmunity, can be traced back to events in the first few months after birth, although the mechanisms were poorly understood. Now, researchers show a connection between breast milk, beneficial gut bacteria and the development of the immune system.
Omega-3 Fatty Acids May Hold Key to Unlocking Blood-Brain Barrier
Researchers have obtained a 3D structure of the transporter protein that provides a gateway for omega-3s to enter the brain, possibly informing drug design.
SARS-CoV-2 May Have the Ability To Reactivate Dormant Tuberculosis
In a study, scientists found that infection with a specific coronavirus strain reactivated dormant Mycobacterium tuberculosis in mice.
Small Epigenomic Signals Matter in the Human Brain, Here’s Why
Researchers have carried out the largest study to date on the regulatory elements in the genome of primates. They found that in humans, the weakest regulatory signals, that are not usually studied, play an important role in the regulation of genes linked to brain.
Antarctic Ozone Pollution Has Increased
Ozone very high in the atmosphere’s ozone layer absorbs damaging ultraviolet radiation, but is a pollutant at ground level. Researchers have analyzed more than 25 years of Antarctic data, finding that concentrations near the ground arose from both natural and human-related sources.
Bioactive Packaging Keeps Strawberries Fresh
Researchers have developed a packaging film that can keep strawberries fresh for up to 12 days.
How Do Immune Cells Become Activated?
By studying the structure of cellular receptors and of the molecules that activate them, scientists are deciphering the details of immune cell activation.
