A new study reports that among individuals who had an allergic reaction to their first mRNA COVID-19 vaccine dose, all who went on to receive a second dose tolerated it. Even some who experienced anaphylaxis following the first dose tolerated the second dose.

Soft materials, like skin, behave differently than hard materials when punctured. They provide an unstable resistance that is more difficult to describe and hence predict. Researchers at the University of British Columbia have answered the previously unsolved question of how the mechanics of piercing works on soft materials by studying solutions from the natural world, and have created a...

A new study describes a new liquid phase in thin films of a glass-forming molecules. These results demonstrate how these glasses and other similar materials can be fabricated to be denser and more stable, providing a framework for developing new applications and devices through better design.

In an analysis of almost 3 million patients taking a single high blood pressure medication for the first time, angiotensin receptor blockers (ARBs) were as good as angiotensin-converting enzyme (ACE) inhibitors at preventing cardiovascular events linked to hypertension, including heart attack, stroke and heart failure.51 possible side effects and safety concerns were examined: The patients taking...

What The Study Did: Survey data were used to investigate the relationship between loneliness and high-risk medication use in adults older than age 65.

A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, but the results could help to illuminate an important evolutionary process in many species. The research centers on a process known as sex chromosome dosage compensation.

Tokyo, Japan - Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate a 3D acoustic fields which stably trapped and lifted a small polystyrene ball from a reflective surface. Although their technique employs a method similar to...

UC San Diego researchers and their colleagues at the Icahn School of Medicine at Mount Sinai in New York have discovered that spontaneous impulses of dopamine, the neurological messenger known as the brain's "feel good" chemical, occur in the brain of mice. The study found that mice can willfully manipulate these random dopamine pulses for reward.

Researchers from the Universitat Autònoma de Barcelona (UAB) Department of Mathematics worked in collaboration with the Hospital de Mataró in developing an artificial intelligence-based model for predicting the risk of death of intensive care unit patients according to their characteristics. The model will improve the quality of care in these types of units.

There are many reasons that an intranasal vaccine against the SARS-CoV-2 virus would be helpful in the fight against COVID-19 infections, University of Alabama at Birmingham immunologists Fran Lund, Ph.D., and Troy Randall, Ph.D., write in a viewpoint article in the journal Science.

Last year, the American Cancer Society (ACS) issued an updated set of guidelines for cervical cancer screening - emphasizing the shift toward screening with primary human papillomavirus (HPV) testing. While the ACS recommendation accounts for a transition period to implement primary HPV screening, additional factors should be considered to operationalize these guidelines, according to a special...

In the first wealth and longevity study to incorporate siblings and twin pair data, researchers from Northwestern University analyzed the midlife net worth of adults (mean age 46.7 years) and their mortality rates 24 years later. They discovered those with greater wealth at midlife tended to live longer.

What The Study Did: Researchers investigated the association between net worth at midlife and subsequent longevity in individuals as well as with siblings and twins.

EPFL researchers have characterized a mechanism that allows bacteria to direct their movement in response to the mechanical properties of the surfaces the microbes move on -- a finding that could help fight certain pathogens.

New research by an Executive PhD Research student at the Business School (formerly Cass) outlines how elderly patients with neurological conditions are significantly more likely to develop delirium shortly after they are hospitalised, and those admitted on Sunday and Tuesday are more likely to develop the disorder.

Researchers at Aalto University have used lignin, a natural polymer abundant in wood and other plant sources, to create a safe, low-cost and high-performing coating for use in construction. As there is a global urge to meet the rising sustainability standards, this new coating has great potential to protect wood, whose use in construction is continually increasing. The new coating is non-toxic,...

Scientists have created plants whose cells and tissues 'blush' with beetroot pigments when they are colonised by fungi that help them take up nutrients from the soil. This is the first time this vital, 400 million year old process has been visualised in real time in full root systems of living plants. Understanding the dynamics of plant colonisation by fungi could help to make food production...

Researchers have discovered a previously unknown repair process in the brain that they hope could be harnessed and enhanced to treat seizure-related brain injuries.

As reported in Advanced Photonics, researchers from Shanghai University and Fudan University developed a general framework and metadevices for achieving dynamic control of THz wavefronts. Instead of locally controlling the individual meta-atoms in a THz metasurface (e.g., via PIN diode, varactor, etc.), they vary the polarization of a light beam with rotating multilayer cascaded metasurfaces.

A collaboration led by St. Jude Children's Research Hospital, Shanghai Children's Medical Center and others revealed how thiopurines produce mutations that lead to multi-drug resistant leukemia and relapse.

Most children with a mental health disorder are not receiving services to address their needs--according to a new study from researchers at Simon Fraser University's Children's Health Policy Centre. Their research was published this week in the journal Evidence-Based Mental Health.

About six gigatons -- roughly 12 times the mass of all living humans -- of carbon appears to be emitted over land every year, according to data from the Chinese Global Carbon Dioxide Monitoring Scientific Experimental Satellite (TanSat).

St. Jude Children's Research Hospital study highlights the power of comprehensive whole genome, whole exome and RNA sequencing to better understand and treat each patient's cancer.

Scientists revealed strong isotope effects in photodissociation of the water isotopologue (HOD) using the Dalian Coherent Light Source.
