Gene therapy currently represents the most promising approach for the treatment of hereditary diseases. Yet despite significant breakthroughs in recent years, there are still a number of hurdles that hinder the wider application of gene therapies. These include the efficient delivery of genetic material into target cells with minimal side effects using adeno-associated viral vectors (AAVs). The AAV carrier substances have an advantageous safety profile and high gene transfer efficiency, meaning they are often used in gene therapies and in gene editing with CRISPR/Cas. But, AAVs have limited DNA uptake capacity ...

An artificial intelligence tool effectively detected distress in hospital workers’ conversations with their therapists early in the pandemic, a new study shows, suggesting a potential new technology that screens for depression and anxiety. As the coronavirus pandemic forced many hospitals to operate beyond capacity, medical workers faced overwhelming numbers of work shifts, limited rest, and increased risk of COVID-19 infection. At the same time, quarantine policies and fear of infecting family reduced their ...

If you’ve ever watched a bumblebee move from flower to flower, you might wonder how they decide which flower to choose and how long to stay. Now, researchers reporting in the journal iScience on October 24 have new insight based on their observations of bumblebees’ interactions with slippery artificial flowers. They found that the bumblebees make choices to maximize the rate of energy return, or the amount of sugar collected each minute. “Bumblebees can make decisions ‘on the fly’ about which nectar sources are the most energetically economical,” said Jonathan ...

When it comes to the question of who gets to be a scientist, gender disparities are well-documented in many fields.

Further research is needed to determine the mechanism of action of Tongxinluo in STEMI.  Authors: Yuejin Yang, M.D., Ph.D., and Runlin Gao, M.D., of the Chinese Academy of Medical ...

Research has found that bumblebees make foraging choices to collect the most sugar from flowers in the shortest time – even if that means using more energy in the process – to provide an immediate energy boost for the colony. A new study investigating nectar drinking in one of the most common bumblebees in the UK, Bombus terrestris, has found that when foraging they maximise the amount of nectar sugar they take back to the colony each minute. To make their choices, the bumblebees trade off the time they spend collecting nectar with the energy content of that nectar. This means ...

About The Study: In this examination of SARS-CoV-2 incidence and transmission in child care centers (CCCs) and students’ households, transmission within CCCs and from children infected at CCCs into households was low in this study that included 83 children in 11 CCCs. These findings suggest that current testing and exclusion recommendations for SARS-CoV-2 in CCCs should be aligned with those for other respiratory viruses with similar morbidity and greater transmission to households. Authors: Timothy R. Shope, ...

About The Study: The results of this study of 91,460 mother-offspring pairs found no association between in utero corticosteroid and β2-adrenergic agonist exposure and offspring neurodevelopmental outcomes, regardless of the timing of exposure.

Why would someone decide to give their money to help a stranger bring a creative project to life? Recent research has found that backers of crowdfunding projects participate, in part, because of a sense of indirect success and the feeling that they are contributing to something bigger. Crowdfunding — raising money for a new venture by collecting small amounts from many people — is most often done online, and messaging on the most popular sites reinforces the perception of a more democratic market. But the reality is a bit ...

CORVALLIS, Ore. – An international coalition of climate scientists says in a paper published today that the Earth’s vital signs have worsened beyond anything humans have yet seen, to the point that life on the planet is imperiled.
