Ubiquitous food additive alters human microbiota and intestinal environment
New clinical research indicates that a widely used food additive, carboxymethylcellulose, alters the intestinal environment of healthy persons, perturbing levels of beneficial bacteria and nutrients. These findings, published in Gastroenterology, demonstrate the need for further study of the long-term impacts of this food additive on health. The research was led by a collaborative team of […]
Artificial intelligence successfully predicts protein interactions: Research could lead to a wealth of drug targets
UT Southwestern and University of Washington researchers led an international team that used artificial intelligence (AI) and evolutionary analysis to produce 3D models of eukaryotic protein interactions. The study, published in Science, identified more than 100 probable protein complexes for the first time and provided structural models for more than 700 previously uncharacterized ones. Insights […]
Research in mice shows how diet alters immune system function through a gut microbe
The cliché “you are what you eat” has been used for hundreds of years to illustrate the link between diet and health. Now, an international team of researchers has found the molecular proof of this concept, demonstrating how diet ultimately affects immunity through the gut microbiome. The work, conducted in mice, reveals that what animals […]
Hubble tension: Showing the cracks in Gaussian Processes
The technique of Gaussian Processes (GP) is widely used to reconstruct cosmological parameters, most notably the expansion rate of the universe, using observational data. For many cosmologists, the crowning achievement of this approach is its ‘model independence’ — meaning it can be applied universally across all models. Through new analysis published in EPJ C, Eoin […]
DNA analysis confirms 2,000-year-old sustainable fishing practices of Tsleil-Waututh Nation
Ancient Indigenous fishing practices can be used to inform sustainable management and conservation today, according to a new study from Simon Fraser University. Working with the Tsleil-Waututh Nation and using new palaeogenetic analytical techniques developed in SFU Archaeology’s ancient DNA lab, directed by professor Dongya Yang, the results of a new collaborative study featured in […]
Breakup of a single chemical bond measured
The team used a high-resolution atomic force microscope (AFM) operating in a controlled environment at Princeton’s Imaging and Analysis Center. The AFM probe, whose tip ends in a single copper atom, was moved gradually closer to the iron-carbon bond until it was ruptured. The researchers measured the mechanical forces applied at the moment of breakage, […]
Smartphone sensor data has potential to detect cannabis intoxication: New report demonstrates how phone sensor data, such as GPS, can be used to detect cannabis intoxication in young adults.
A smartphone sensor, much like what is used in GPS systems, might be a way to determine whether or not someone is intoxicated after consuming marijuana, according to a new study by the Rutgers Institute for Health, Health Care Policy and Aging Research. According to the study, published in Drug and Alcohol Dependence, which evaluated […]
What Is a Suicidal Ideation Scale? Suicide Screening
Suicidal ideation scales are clinical tools used to assess a person’s risk of committing suicide and therefore help in timely intervention and treatment A suicidal ideation scale is a clinical tool used to assess a person’s risk of committing suicide. By helping healthcare providers recognize signs that someone is likely to self-injure, the scale aids […]
Surgical Tray Recalled After Two Infant Deaths
Cardinal Health issued a recall of an insertion tray used during emergency intravenous catheter placement for critically ill newborns after its scalpel was implicated in the death of two infants, the FDA said on Friday. Notably, the agency classified this as a class I recall, the most serious type, which is reserved for cases where […]
Humans aren’t the only species whose metabolisms tend to slow down with age
If you feel like your metabolism just isn’t what it used to be, no matter how many hours you spend in the gym, dolphins can relate. A Duke University-led study finds that bottlenose dolphins burn calories at a lower rate as they get older, just like we do. It’s the first time scientists have measured […]
