May 14, 2021 - Two thirds of all pediatric spinal fractures, especially in the adolescent population, occur in motor vehicle accidents (MVAs) where seatbelts are not utilized, reports a study in Spine.
ITHACA, NY, May 13, 2021 -- Cyanobacteria are one of the unsung heroes of life on Earth. They first evolved to perform photosynthesis about 2.4 billion years ago, pumping tons of oxygen into the atmosphere - a period known as the Great Oxygenation Event - which enabled the evolution of multicellular life forms.
The United States has witnessed a steep rise in reports, arrests, and media coverage of teachers' sexual misconduct with students. A new study investigated the impact of perpetrators' gender, sexuality, and age on perceptions of teacher sexual misconduct. The study found that
responses to teachers' misconduct varied according to certain characteristics, which can influence whether victims report the misconduct.
The study, by researchers at Prairie View A&M University and the University of Nevada, Reno, appears in Feminist Criminology.
What if you could predict which cells might become cancerous? Breast tissue changes dramatically throughout a woman's life, so finding markers for sudden changes that can lead to cancer is especially difficult. Cold Spring Harbor Laboratory (CSHL) Associate Professor Camila dos Santos and her team identified and cataloged thousands of normal human and mouse breast cell types. The new catalog redefines healthy breast tissue so that when something goes awry, scientists can pinpoint its origin.
Any breast cell could become cancerous. Dos Santos says:
Next-generation sequencing technology has made it easier than ever for quick diagnosis of plant diseases. "It's really exciting to see how sequencing technologies have evolved and how this new technology facilitates sequencing of entire genomes in such a short amount of time," said Yazmín Rivera, a plant pathologist with the United States Department of Agriculture's Plant Protection and Quarantine program, who recently published a research paper on the efficacy of Oxford Nanopore Technologies protocols.
Dozens of commonly used drugs, including antibiotics, antinausea and anticancer medications, have a potential side effect of lengthening the electrical event that triggers contraction, creating an irregular heartbeat, or cardiac arrhythmia called acquired Long QT syndrome. While safe in their current dosages, some of these drugs may have a more therapeutic benefit at higher doses, but are limited by the risk of arrhythmia.
Even the mention of lavender evokes the distinct fragrance of the flower. This beautiful flower has been used to make perfumes and essential oils since time immemorial. The aesthetics of the flower have captured the imagination of hundreds, worldwide. So, what makes this flower so special? What are the "magical" compounds that gives it its unique fragrance? What is the genetic basis of these compounds? These questions have long puzzled scientists.
Hamilton, ON (May 15, 2021) - A simple surgery saves patients with heart arrhythmia from often-lethal strokes, says a large international study led by McMaster University.
Researchers found that removing the left atrial appendage -- an unused, finger-like tissue that can trap blood in the heart chamber and increase the risk of clots -- cuts the risk of strokes by more than one-third in patients with atrial fibrillation.
Researchers at Rutgers Robert Wood Johnson Medical School are reporting the first instance of COVID-19 triggering a rare recurrence of potentially serious blood clots in people's arms.
The discovery, published in the journal Viruses, improves the understanding of how inflammation caused by COVID-19 can lead to upper extremity blood clots and how best to treat them. The case study is part of a larger Rutgers study of 1,000 hospitalized patients diagnosed with COVID-19 who were admitted and discharged between March and May 2020.
Psychology researchers at UC Santa Cruz have found that playing games in virtual reality creates an effect called "time compression," where time goes by faster than you think. Grayson Mullen, who was a cognitive science undergraduate at the time, worked with Psychology Professor Nicolas Davidenko to design an experiment that tested how virtual reality's effects on a game player's sense of time differ from those of conventional monitors.
ATS 2021, New York, NY - The use of e-cigarettes is associated with wheezing and shortness of breath in young adults and adolescents, even in those who don't smoke cigarettes or marijuana, according to research presented at the ATS 2021 International Conference.
ATS 2021, New York, NY - Individuals with asthma who live in redlined neighborhoods have worse lung function than those in locales that excluded Black people and benefited from decades of inequitable wealth accumulation at the expense of Black communities in the United States, according to research presented at the ATS 2021 International Conference.

ATS 2021, New York, NY - While vaping is thought to be a safer alternative to smoking, teens and adults who use e-cigarettes have increased odds of developing asthma and having asthma attacks, according to research presented at the ATS 2021 International Conference.

ATS 2021, New York, NY - Having genetic risk variants in the ABO gene might significantly increase the chances of developing COVID-19, and other genes may also increase COVID-19 risk, according to research presented at the ATS 2021 International Conference.
The mysteries of sexual attraction just became a little less mysterious - at least for moths. A team of six American and European research groups including Tufts University has discovered which gene expressed in the brain of the male European corn borer moth controls his preference for the sex pheromone produced by females. This complements a previous study on the gene expressed in the female pheromone gland that dictates the type of blend she emits to attract males. The study was reported today in Nature Communications.
