Researchers can gather highly accurate information about social trends and groups by asking about a person's social circle rather than interrogating their own individual beliefs.
A large cohort study drawn from the national IVF registry of France, which included almost 70,000 pregnancies delivered after 22 weeks gestation between 2013 and 2018, has found a higher risk of pre-eclampsia and hypertension in pregnancies derived from frozen-thawed embryos. This risk was found significantly greater in those treatments in which the uterus was prepared for implantation with hormone replacement therapies. The results confirm with real-life data what has been observed in sub-groups of patients in other studies.
The tiny beetle Triamyxa coprolithica is the first-ever insect to be described from fossil feces. The animal the researchers have to thank for the excellent preservation was probably the dinosaur ancestor Silesaurus opolensis, which 230 million years ago ingested the small beetle in large numbers.
Harpy eagles (Harpia harpyja) - which are among the world's largest eagle species - struggle to feed offspring in heavily deforested areas of the Amazon, according to a study published in Scientific Reports.
In an article published today in Nature, Sanaria's PfSPZ-CVac (CQ) vaccine is reported as being safe and protecting 100% of six subjects against a variant malaria parasite three months after their last dose in the company's Phase 1 safety and efficacy trial. This is the first time complete protection against a variant malaria parasite has ever been achieved that long after vaccine administration.
MIT neuroscientists have uncovered a common neural mechanism for cognitive impairments seen in some people with autism and schizophrenia, even though the genetic variations that produce the impairments are different for each disorder.
Almost 90 years later, a team of physicists co-led by Hongkun Park and Eugene Demler in the Faculty of Arts and Sciences has finally experimentally document quantum melting of Wigner Crystals.
A new NIMH-supported study found that eating disorder behaviors alter the brain's reward response process and food intake control circuitry, which can reinforce the behaviors.
The link between obesity and the risk of endometrial cancer has been well documented. A new study, however, shows that an even lower body mass index (BMI) than previously thought can signal an increased risk in Asian women with postmenopausal bleeding. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
Neuroscientists at UCL have, for the first time, identified abnormalities in the way memories are 'replayed' in the brains of people with schizophrenia; researchers say the pathbreaking study provides an entirely new basis for explaining many of the condition's core symptoms.
A new study by investigators from Brigham and Women's Hospital examines the associations between wealth mobility and long-term cardiovascular health.
Two U.S. Phase 1 clinical trials of a novel candidate malaria vaccine have found that the regimen conferred unprecedentedly high levels of durable protection when volunteers were later exposed to disease-causing malaria parasites. The vaccine combines live parasites with either of two widely used antimalarial drugs -- an approach termed chemoprophylaxis vaccination. A Phase 2 clinical trial of the vaccine is now underway in Mali, a malaria-endemic country.
What The Study Did: This crossover trial found that perceived breathing resistance at peak exercise is uniquely and significantly elevated when exercise stress testing (EST) is performed while wearing a mask. Performing EST with a mask yielded lower peak exercise oxygen uptake and heart rates as compared with no mask.
What The Study Did: Researchers in this randomized clinical trial found that a large proportion of patients who canceled visits and procedures early in the COVID-19 pandemic didn't reschedule once reopening occurred.
What The Study Did: National survey data were used to estimate how common psoriasis is among adults in the United States and how this has changed since 2003.
What The Study Did: Researchers investigated the association between a midlife change in wealth and the risk of cardiovascular event after age 65.
What The Study Did: This survey study investigated the association between general surgery resident grit, which was defined as perseverance and passion for long-term goals, and burnout and thoughts of attrition and suicide.
Results of a new study led by researchers at Boston Medical Center (BMC) show, however, that this expansion did not lead patients receiving care at safety-net hospitals to transfer their care to non-safety-net hospitals.
All these preclinical data strongly suggest that the inhibition of mTORC1 and PLK1 proteins may be a promising therapeutic approach for NSCLC patients
A promising approach captures atmospheric carbon dioxide and then through CO2 electrolysis converts it into value-added chemicals and intermediates, like ethanol. Reducing the energy consumption of this high-power process has been underexplored. In ACS Energy Letters, researchers from the University of Illinois Urbana-Champaign report a new opportunity to use magnetism to reduce the energy required for CO2 electrolysis by up to 60% in a flow electrolyzer.
Amyotrophic lateral sclerosis, or ALS, attacks nerve cells known as motor neurons in the brain and spinal cord, gradually leading to paralysis. The loss of function of an important gene, C9orf72, may affect communication between motor neurons and muscles in people with this disease. These findings were revealed by the team of Dr Kessen Patten of the Institut national de la recherche scientifique (INRS) in the prestigious journal Communications Biology.
Analysis of the nanostructure and in-situ structural evolution of Zr-doped NVPF completely coated with nitrogen-doped carbon.
Researchers at Chalmers University of Technology, Sweden, have succeeded in developing a method to label mRNA molecules, and thereby follow, in real time, their path through cells, using a microscope - without affecting their properties or subsequent activity. The breakthrough could be of great importance in facilitating the development of new RNA-based medicines.
The Zwicky Transient Facility has identified an extremely magnetized and rapidly rotating ultra-massive white dwarf. Several telescopes characterized the dead star, including two Hawai'i observatories -- W. M. Keck Observatory on Maunakea, Hawai'i Island and University of Hawai'i Institute for Astronomy's Pan-STARRS on Haleakala, Maui.
Spatial reasoning ability in small children reflects how well they will perform in mathematics later. Researchers from the University of Basel recently came to this conclusion, making the case for better cultivation of spatial reasoning.
