While grocery stores remained open as an essential business and thrived financially throughout the pandemic, researchers shows people went to the grocery store less frequently and spent more per trip during the pandemic. New research found that like food-secure individuals, food-insecure individuals made fewer grocery shopping trips due to concerns about contracting COVID-19. But, unlike food-secure individuals, they did not increase spending per trip.

In addition to chemical factors, mechanical influences play an important role in the natural growth of human organs such as kidneys, lungs and mammary glands - but also in the development of tumors. Now a research team at the Technical University of Munich (TUM) has investigated the process in detail using organoids, three-dimensional model systems of such organs which are produced in the laboratory.

A recently published study co-authored by University of Kentucky Sanders-Brown Center on Aging researcher Justin Miller, Ph.D., identifies 11 rare candidate variants for Alzheimer's disease. Researchers found 19 different families in Utah that suffered from Alzheimer's disease more frequently than what is considered normal.

Skoltech team has developed a model for assessing infection risks for supermarket customers. The researchers believe that their model will help formulate scientifically backed rules for safe shopping during the pandemic. Curiously enough, the team discovered that increasing customer density has only a slight positive effect on sales, so filling the store to the limit makes little sense not just epidemiologically but economically, too.

Approximately 15% of lung cancer tumors are caused by a mutation in a growth receptor called EGFR. An effective drug can kill most of the cancer cells, but the tumor eventually grows back. CSHL Visiting Scientist Raffaella Sordella and her team investigated the molecular mechanisms behind this relapse. They discovered that some of the cells were resistant to the EGFR treatment; they survived using a parallel pathway.

Scientists have found new evidence of menopause in killer whales - raising fascinating questions about how and why it evolved.

Two very different teams of scientists have worked together to reveal important insights into how we sense texture by looking at the whiskers of a rat.

As the complexity of radiation therapy has grown, so too has the amount of data that goes into treatment machines. With more data comes more opportunity for errors in data transfer. Ramon Alfredo Siochi--WVU's director of medical physics--is working to make those errors less likely.

A University of Iowa study shows that a diet rich in isoflavone, a phytoestrogen or plant-based compound that resembles estrogen, protects against multiple sclerosis-like symptoms in a mouse model of the disease. Importantly, the isoflavone diet was only protective when the mice had gut microbes capable of breaking down the isoflavones.

Using a novel imaging approach, researchers discovered that the journey of the egg and the embryo through the fallopian tube is more dynamic and complex than previously thought.

Researchers have now discovered a new set of signals that control the production of goblet cells in the lung.

Teenagers who have self-harmed five or more times in their life have a significantly higher threshold for pain compared to adolescents that have not.

Patients with Achilles tendinopathy, a disease of the Achilles tendon that can potentially cause significant pain, receive no benefit from being treated with platelet rich plasma (PRP) injection, a clinical trial led by the University of Warwick has found.

The team led by Alejo Efeyan, head of the Metabolism and Cell Signalling Group at the Spanish National Cancer Research Centre (CNIO), has discovered that genetic inhibition of the RagC protein blocks the activation of B lymphocytes and delays the onset of follicular lymphomas without side effects. The study, which was carried out in animal models, was published this week in the journal Cell Reports.

Researchers from Osaka University have found that protein phosphatase 1 binds to RIF1 at double-strand DNA breaks to promote repair by the non-homologous end joining pathway instead of the homologous recombination pathway. Given the key role of double-strand break repair in cancers such as hereditary breast and ovarian cancer, the insight gained from this study could help develop novel therapeutic options in the future.

What The Study Did: Researchers used a large data resource of U.S. COVID-19 cases and control patients who tested negative from multiple health systems across the country to evaluate COVID-19 severity and risk factors over time and assess the use of machine learning to predict clinical severity.

A new wearable device turns the touch of a finger into a source of power for small electronics and sensors. Engineers at the University of California San Diego developed a thin, flexible strip that can be worn on a fingertip and generate small amounts of electricity when a person's finger sweats or presses on it. What's special about this sweat-fueled device is that it generates power even while the wearer is asleep or sitting still.

Substantially more people in the U.S. with opioid use disorder are receiving evidence-based treatment for the disease, but there are still considerable gaps in care along racial lines, according to the largest analysis to date of opioid use disorder among Medicaid recipients.

No longer science fiction, farm robots are already here--and they have created two possible extremes for the future of agriculture and its impacts on the environment, argues agricultural economist Thomas Daum in a Science & Society article published July 13 in the journal Trends in Ecology & Evolution.

In Biophysics Reviews, researchers provide an update on how electrical impulses in the heart travel from cell to cell. The connections between cells forming the low resistance pathway and facilitating the current flow are called gap junctions. Each consists of many channels, which are formed when specific proteins from one cell dock and fuse to the proteins from another cell. The scientists delve into the properties of gap junctions and their constituent proteins.
