(Press-News.org) About The Study: The findings of this study including more than 3 million patients receiving the mRNA COVID-19 vaccine suggest that retinal vascular occlusion (RVO) diagnosed acutely after vaccination occurs extremely rarely at rates similar to those of two different historically used vaccinations, the influenza and tetanus, diphtheria, pertussis (Tdap) vaccines. No evidence suggesting an association between the mRNA COVID-19 vaccination and newly diagnosed RVO was found.

[EMBARGOED] The 2020 election saw fewer people clicking on misinformation websites, Stanford study finds
2023-04-13
In the run-up to the 2020 election, people appear to have become savvier in spotting misinformation online: clicks onto unreliable websites have declined, according to a new Stanford study published April 13 in the journal Nature Human Behaviour. According to prior research, some 44.3 percent of Americans visited websites during the 2016 U.S. election that repeatedly made false or misleading information.
During the 2020 election, Stanford scholars saw that number drop by nearly half to 26.2 percent.
While these findings ...
Curtin researchers map genetic signature of precursor to liver cancer
2023-04-13
Researchers at Curtin University have identified the genetic signature of pre-malignant liver cells, offering potentially significant implications for the almost 3,000 Australians diagnosed with the deadly cancer each year.
The study, published in the prestigious journal Cell Genomics, found that quantifying pre-malignant liver cells in patients with liver disease could help determine their future risk of developing liver cancer.
First author Dr Rodrigo Carlessi, from the Curtin Medical School and the Curtin Health Innovation Research Institute, said the discovery had the potential to save lives by changing how chronic liver disease patients ...
One brain, multiple and simultaneous alternative decision strategies
2023-04-13
Choosing a checkout line in a supermarket might seem like a no-brainer, but it can actually involve a complex series of cerebral computations. Maybe you count the number of shoppers in each line and pick the shortest, or estimate the number of items on each conveyor belt. Perhaps you quickly weigh up both shoppers and items and maybe even the apparent speed of the cashier... In fact, there are a multiplicity of strategies for solving this problem.
So how does the brain know how to make decisions ...
Researchers warn of tick-borne disease babesiosis
2023-04-13
RIVERSIDE, Calif. -- 'Tis the season for hiking now that spring has arrived and temperatures are on the upswing. But with hikes come insect bites and on the increase in North America is babesiosis, a malaria-like disease spread especially between May and October by a tick.
Indeed, recent research suggests an increase in the incidence of diseases transmitted by ticks around the world, not just the United States and Canada, due likely to climate change and other environmental factors. Among the tick-borne pathogens, Babesia parasites, which infect and destroy red blood cells, are considered a serious ...
Where did the first sugars come from?
2023-04-13
LA JOLLA, CA— Two prominent origin-of-life chemists have published a new hypothesis for how the first sugars—which were necessary for life to evolve—arose on the early Earth.
In a paper that appeared on April 13, 2023, in the journal Chem, the chemists from Scripps Research and the Georgia Institute of Technology propose that key sugars needed for making early life forms could have emerged from reactions involving glyoxylate (C2HO3–), a relatively simple chemical that plausibly existed on the Earth before life evolved.
“We show that our new hypothesis has key advantages over the more traditional view ...
Conservation: Red-throated loons avoid North Sea windfarms
2023-04-13
Offshore wind farms in the North Sea reduce the population of loons –fish-eating aquatic birds also known as divers – by 94% within a one-kilometre zone, according to new research published in Scientific Reports. The findings highlight the need to minimise the impact of offshore wind farms on seabirds, while balancing this effort with the demand for renewable energy.
Previous research has found that different seabird species respond to offshore windfarms differently – they may avoid the area which can lead to habitat displacement or they may be attracted to the area which can increase mortality via collisions with the turbines. However, it is difficult ...
Why orchid bees concoct their own fragrance
2023-04-13
Male bees display a remarkable passion for collecting scents: they deposit scents from various sources in special pockets on their hind legs, thus composing their own fragrance. This behaviour has been known since the 1960s. The reason why they do it has been the subject of much speculation just as long. Researchers from Ruhr University Bochum, Germany, in collaboration with colleagues from the University of California at Davis and the University of Florida at Fort Lauderdale, have finally solved the mystery. The bee fragrance serves as a sex attractant and increases the reproductive success of the males, as the team found out after three years ...
Uncovering hidden mitochondrial mutations in single cells
2023-04-13
A high-throughput single-cell single-mitochondrial genome sequencing technology known as iMiGseq has provided new insights into mutations of mitochondrial DNA (mtDNA) and offers a platform for assessing mtDNA editing strategies and genetic diagnosis of embryos prior to their implantation.
An international team of researchers, led by KAUST stem cell biologist Mo Li, has now quantitatively depicted the genetic maps of mtDNA in single human oocytes (immature eggs) and blastoids (stem cell-based synthetic embryos)[1]. This has revealed molecular features of rare mtDNA mutations that cause maternally inherited diseases.
Mitochondria, the ...
Effectiveness of COVID-19 mRNA vaccination for children and adolescents confirmed by multi-state study
2023-04-13
A multi-state study from the Centers for Disease Control and Prevention’s (CDC’s) VISION Network confirms that the Pfizer-BioNTech mRNA COVID-19 vaccine has provided children and adolescents, ages 5-17, with protection against both moderate and severe COVID-19 outcomes.
The study found that for 12-17 year olds, vaccine effectiveness was high against the Delta variant but lower during Omicron dominance, including BA.4 and BA.5. Due to the youngest age (5-11) group’s ineligibility for vaccination during Delta predominance, vaccine effectiveness could be estimated for these children only during the Omicron predominant ...

The selection process is overseen by the NCCN Oncology Research Program (ORP) which will also provide oversight.
“It is a privilege to support these emerging innovators ...
