While earlier research has mostly looked into factors such as fear, perceived risk, age and political views to determine what makes individuals and societies more or less willing to drastically change their lifestyle and support government-imposed strict restrictions, in order to mitigate the spread of the COVID-19 pandemic, psychologists at the University of Zurich Charlotte Kukowski, Katharina Bernecker and Veronika Brandstätter took a different perspective.
AUSTIN, Texas -- In the perpetual arms races between bacteria and human-made antibiotics, there is a new tool to give human medicine the edge, in part by revealing bacterial weaknesses and potentially by leading to more targeted or new treatments for bacterial infections.
A research team led by scientists at The University of Texas at Austin has developed chemical probes to help identify an enzyme, produced by some types of E. coli and pneumococcal bacteria, known to break down several common types of antibiotics, making these bacteria dangerously resistant to treatment.
Study Exploring Optimization of Duplex Velocity Criteria for Diagnosis of Internal Carotid Artery (ICA) Stenosis Published Online
Online first in Vascular Medicine, researchers from the Intersocietal Accreditation Commission (IAC) Vascular Testing division report findings of their multi-centered study of duplex ultrasound for diagnosis of internal carotid artery (ICA) stenosis. 1
Aging published "Potential reversal of epigenetic age using a diet and lifestyle intervention: a pilot randomized clinical trial" which reported on a randomized controlled clinical trial conducted among 43 healthy adult males between the ages of 50-72. The 8-week treatment program included diet, sleep, exercise and relaxation guidance, and supplemental probiotics and phytonutrients.
More than 500,000 people have died from COVID-19 in Latin America and the Caribbean, demonstrating the health and economic inequalities throughout the region. A new article analyzes seven books* that discuss these inequalities, including questions of who gets health care and what interdependent roles societies, social movements, and governments play. To end inequality in the region, the author calls for a universal approach to health care.
Although it is not spread through human contact, Francisella tularensis is one of the most infectious pathogenic bacteria known to science--so virulent, in fact, that it is considered a serious potential bioterrorist threat. It is thought that humans can contract respiratory tularemia, or rabbit fever--a rare and deadly disease--by inhaling as few as 10 airborne organisms.
On scales too small for our eyes to see, the business of life happens through the making of proteins, which impart to our cells both structure and function. Cellular proteins get their marching orders from genetic instructions encoded in DNA, whose sequences are first copied and made into RNA in a multi-step process called transcription.
SAN ANTONIO (May 27, 2021) — One-fifth of babies who inherit a genetic variant located on chromosome 16 will develop autism spectrum disorder (ASD) by age 3. The variant is called 16p11.2 deletion.
May 27, 2021 - Patients undergoing total hip arthroplasty (THA) show significant reduction in pain and other symptoms and improvement in walking gait biomechanics. However, those improvements do not lead to increased daily physical activity levels, reports a study in The Journal of Bone & Joint Surgery.
LA JOLLA, CA--Even before the COVID-19 pandemic, most people in the United States already had been sick with a coronavirus, albeit a far less dangerous one. That's because at least four coronaviruses in the same general family as SARS-CoV-2 cause the benign yet annoying illness known as the common cold.

Viruses are perfect molecular machines. Their only goal is to insert their genetic material into healthy cells and thus multiply. With deadly precision, they thereby can cause diseases that cost millions of lives and keep the world on edge. One example for such a virus, although currently less discussed, is HIV that causes the ongoing global AIDS-epidemic. Despite the progress made in recent years, 690 000 people died in 2019 alone as a result of the virus infection.
People living in deprived, less affluent neighborhoods spent less time indoors at home during lockdown, according to a study that tracked data from millions of mobile phone users across the United States.
A new study exploits the characteristic epigenetic signatures of childhood tumors to detect, classify and monitor the disease. The scientists analyzed short fragments of tumor DNA that are circulating in the blood. These "liquid biopsy" analyses exploit the unique epigenetic landscape of bone tumors and do not depend on any genetic alterations, which are rare in childhood cancers. This approach promises to improve personalized diagnostics and, possibly, future therapies of childhood tumors such as Ewing sarcoma. The study has been published in Nature Communications.
Researchers from Tulane University and University of Maryland published a new paper in the Journal of Marketing that examines the dynamic interplay between free and paid versions of an app over its lifetime and suggests a possible remedy for the failure of apps.
The study, forthcoming in the Journal of Marketing, is titled "Managing the Versioning Decision over an App's Lifetime" and is authored by Seoungwoo Lee, Jie Zhang, and Michel Wedel.
