The Cyclostomata is an ancient group of aquatic colonial suspension-feeders from the phylum Bryozoa. The fact that they have unique placentae has been discovered by researchers at St Petersburg University and the University of Vienna. The coenocytes, i.e. large multinucleate cell structures, originate via nuclear multiplication and cytoplasmic growth among the cells surrounding the early embryo. Interestingly, the coenocytes are commonly found among fungi and plants, yet are quite rare in animals. It is the first time coenocytes have been discovered in placenta.
Although the problem of gender discrimination is already found in the music industry, music recommendation algorithms would be increasing the gender gap. Andrés Ferraro and Xavier Serra, researchers of the Music Technology research group (MTG) of the UPF Department of Information and Communication Technologies (DTIC), with Christine Bauer, of the University of Utrecht (Netherlands), have recently published a paper on gender balance in music recommendation systems in which they ask themselves how the system should work to avoid gender bias.
MINNEAPOLIS/ST.PAUL (04/20/2021) -- University of Minnesota Medical School researchers have offered new ways to think about the immune system thanks to a recent study published in Nature. Their research, which indicates organ tissues become increasingly immune throughout life, may begin to alter fundamental ideas regarding the rules of vaccination and the immune system's function within the body.
PHILADELPHIA - Renter protection policies that have curbed mass evictions during the COVID-19 pandemic have played a key role in preventing the spread of SARS-CoV-2 in U.S. cities, according to a new study published in Nature Communications.
An overgrowth of yeast in the gut within the first few months of life may cause changes to the immune system that increase the risk of asthma later on, shows a study published today in eLife.
Asthma is a common and sometimes difficult-to-manage, life-long lung condition that affects one in 10 children in developed countries. The findings explain a possible cause of asthma and may help scientists develop new strategies to prevent or treat the condition.
FAYETTEVILLE, Ark. - The fearsome tyrannosaur dinosaurs that ruled the northern hemisphere during the Late Cretaceous period (66-100 million years ago) may not have been solitary predators as popularly envisioned, but social carnivores similar to wolves, according to a new study.
The finding, based on research at a unique fossil bone site inside Utah's Grand Staircase-Escalante National Monument containing the remains of several dinosaurs of the same species, was made by a team of scientists including Celina Suarez, University of Arkansas associate professor of geosciences.
TAMPA, Fla (April 20, 2021) — Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain – an early step in the development of Alzheimer’s disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests.
The composition of the street drugs heroin and cocaine has dramatically changed at alarming speeds across the globe. No longer are these street drugs cut with benign materials such as lactose but now cut with up to 17 or more pharmaceutically active and potentially toxic adulterants.
A drug user may buy cocaine today but may end up with a drug cocktail more dangerous then what was bought and assumed was cocaine. This has a profound effect on public health and safety as well as on the individual street drug users during the COVID-19 pandemic.
With alarms sounding about the declining diversity of plants and animals, a related concern with equally profound implications is posed: is the variety of microbial life, including viruses, changing too -- and if so, in which direction and how fast?
Two studies led by Baylor College of Medicine shed new light on the unanswered question of why estrogen receptor-positive (ER+) breast cancer sometimes grows back in the bone and spreads to other tissues despite effective endocrine therapies directed at ER.
April 19, 2021--(BRONX, NY)--Researchers at Albert Einstein College of Medicine have developed a topical drug that regenerates and restores the function of erectile nerves damaged by radical prostatectomy, the most common treatment for localized prostate cancer. The drug was tested in rats, and the findings were published online today in JCI Insight.
Having an epidural during childbirth is not associated with a greater risk of autism in the child, according to a study led by researchers at the Stanford University School of Medicine and the University of Manitoba.
The study, which will publish online April 19 in JAMA Pediatrics, helps resolve questions raised by an earlier, widely criticized report on the topic.
What The Study Did: The association between hearing loss and level of physical activity among U.S. adults ages 60 to 69 was analyzed in this study.
Authors: Frank R. Lin, M.D., Ph.D., of the Johns Hopkins University School of Medicine in Baltimore, is the corresponding author.

Animals are constantly moving and behaving in response to instructions from the brain. But while there are advanced techniques for measuring these instructions in terms of neural activity, there is a paucity of techniques for quantifying the behavior itself in freely moving animals. This inability to measure the key output of the brain limits our understanding of the nervous system and how it changes in disease.
New research is shining light on the importance of farmers' markets' ability to mitigate potential disruptions to distribution networks in the face of system shocks like the COVID-19 pandemic.
In a recent study, the researchers found the markets' regional characteristics play a key role in the decision to move all or parts of their operations online -- and how that decision can help or hinder its surrounding community.
