Evolution of consumption: A psychological ownership framework

Technological innovations are rapidly changing how we consume goods and services. In many domains, we are trading ownership of private material goods for access to use shared and experiential goods and services. This article outlines how the downstream effects of these consumption changes are channeled through their influence on psychological ownership--the feeling that a thing is MINE.

Hospital floors are hotspot for bacteria, creating route of transfer to patients

The floors of hospital rooms are frequently contaminated with antibiotic-resistant bacteria within hours of patient admission, creating a route of transfer of potentially dangerous organisms to patients, according to a study published today as part of the proceedings from Decennial 2020: The Sixth International Conference on Healthcare-Associated Infections. Decennial 2020, an initiative of the CDC and SHEA, was cancelled in March due to the pandemic.

Decaying jellyfish blooms can cause temporary changes to water column food webs

Decaying jellyfish blooms fuel the rapid growth of just a few specific strains of seawater bacteria, causing temporary changes to the water column food web. This is the finding of a new study furthering our understanding of how jellyfish blooms, which are happening with increasing frequency, impact marine ecosystems. It details these fast-growing bacteria effectively reduce the amount of jellyfish detrital material reaching the seafloor, keeping it instead within the water column food web.

Scientists discover new organic compounds that could have helped form the first cells

Chemists studying how life started often focus on biopolymers like peptides and nucleic acids, but modern biopolymers don't form easily without help from living organisms. A possible solution to this paradox is that life started using different components, and many non-biological chemicals were likely abundant in the environment. A new survey of a diverse set of such compounds under primitive environmental conditions found many of these easily formed polymers and some spontaneously formed cell-l

Swiss fatalism protects against negative feelings in the pandemic

Trust or disappointment in government crisis management is an important factor for the general mood, shows a study by the University of Zurich based on surveys in Israel and Switzerland. At the end of April, Israelis were twice as disappointed with their government institutions during the pandemic as Swiss citizens. In Switzerland, a certain fatalism made for less negative feelings.

People with type 2 diabetes need not avoid eating potatoes based on glycemic index

People with type 2 Diabetes (T2D) are frequently told to avoid eating potatoes, and other high Glycemic Index (GI) foods, because of the longstanding perception that these foods make it difficult to control blood sugar levels. However, for the first time, a rigorously controlled clinical trial, including 24 adults with T2D, demonstrates that GI is not an accurate surrogate for an individual's glycemic response (GR) to a food consumed as part of an evening meal.

Cause of Alzheimer's disease traced to mutation in common enzyme

Researchers from Tokyo Metropolitan University have discovered a new mechanism by which clumps of tau protein are created in the brain, killing brain cells and causing Alzheimer's disease. A specific mutation to an enzyme called MARK4 changed the properties of tau, usually an important part of the skeletal structure of cells, making it more likely to aggregate, and more insoluble. Getting to grips with mechanisms like this may lead to breakthrough treatments.

CBD helps reduce lung damage from COVID by increasing levels of protective peptide

One way CBD appears to reduce the 'cytokine storm' that damages the lungs and kills many patients with COVID-19 is by enabling an increase in levels of a natural peptide called apelin, which is known to reduce inflammation and whose levels are dramatically reduced in the face of this storm.

New study shows how complex metabolism may have self-assembled from simple precursors

Life as we know uses energy to reproduce itself. Organisms build and break down larger molecules using a common set of reactive intermediate energy carrier molecules. These carrier molecules help chaperone the reactions which build life's biochemical complexity and help push metabolic reactions to drive cellular reproduction. New research suggests that such compounds can be made easily in the environment in the absence of biology, providing a hint as to how life may have started.

Echo from the past makes rice paddies a good home for wetland plants

Tokyo, Japan - Researchers from Tokyo Metropolitan University studied the biodiversity of wetland plants over time in rice paddies in the Tone River basin, Japan. They found that paddies which were more likely to have been wetland before agricultural use retained more wetland plant species. On the other hand, land consolidation and agricultural abandonment were both found to negatively impact biodiversity. Their findings may one day inform conservation efforts and promote sustainable agriculture
