Geographic access to IVF and other fertility services is significantly higher in the richest parts of Britain, a new study shows. Researchers have warned the current locations of clinics is likely reducing opportunities for those living in more deprived parts of the country to get fertility treatment. Opportunities to have a baby may thus be influenced by a geographical lottery. In 2020 nearly a fifth of local authorities did not have fertility clinics within a radius of 25km, meaning 1.6m women of reproductive ages had no assisted fertility ...

Earth is a dynamic and constantly changing planet. From the formation of mountains and oceans to the eruption of volcanoes, the surface of our planet is in a constant state of flux. At the heart of these changes lies the powerful force of plate tectonics—the movements of Earth’s crustal plates. This fundamental process has shaped the current topography of our planet and continues to play a role in its future. But what was plate tectonic activity like during early Earth? And was the process even occurring during the time when life is thought to have formed? “The dynamic tectonic ...

ITHACA, N.Y. – A new Cornell University-led study suggests that if artificial intelligence tools can counsel a doctor like a colleague – pointing out relevant research that supports the decision – then doctors can better weigh the merits of the recommendation. The researchers will present the new study in April at the Association for Computing Machinery CHI Conference on Human Factors in Computing Systems. Previously, most AI researchers have tried to help doctors evaluate suggestions from decision support tools by explaining how the underlying algorithm works, or what data was used to train the AI. But an ...

The American College of Chest Physicians (CHEST) opposes the federal court’s March 30, 2023, ruling in Braidwood Management Inc. v. Becerra and applauds the Department of Justice for acting so swiftly to appeal this decision. Judge O’Connor’s remedies strip the guarantee of no-cost preventative benefits away from the 151 million people insured by the Affordable Care Act (ACA) and currently have access to care, such as smoking cessation services, guideline-indicated lung cancer screening, and tuberculosis testing. “CHEST’s ...

Cambridge, Mass. - Researchers at the Forsyth Institute have discovered an important mechanism that may have profound implications for how we prevent colorectal cancer. Oddly enough, their discovery began in the mouth.  Colorectal cancer is the second most deadly cancer, killing over 52,000 people a year. Increasing evidence indicates Fusobacterium nucleatum, an opportunistic oral pathogen is one of the factors causing colorectal cancer. Fusobacteria are often found in healthy mouths, living in balance ...

Each year about 1.5 million people in the U.S. survive a traumatic brain injury due to a fall, car accident, or a sports injury, which can cause immediate and long-term disability.   University of Maryland School of Medicine (UMSOM) researchers wanted to better understand what happens in the brain during injury, so they conducted a study in mice to determine how different types of brain cells in mice react to severe trauma. In a new study published in the January issue of Autophagy, they found that after traumatic brain injury, the brain’s immune system cells’ internal recycling ...

Animals, like humans, appear to be troubled by a Linda problem. The famous “Linda problem” was designed by psychologists to illustrate how people fall prey to what is known as the conjunction fallacy: the incorrect reasoning that if two events sometimes occur in conjunction, they are more likely to occur together than either event is to occur alone.  Now, for the first time, UCLA psychology researchers have shown that this type of logical error isn’t the sole province of humans ...

“Cortactin (also known as EMS1 or CTTN) is expressed broadly in a variety of cancers [...]”  BUFFALO, NY- April 4, 2023 – A new editorial paper was published in Oncotarget's Volume 14 on March 21, 2023, entitled, “Impact of cortactin in cancer progression on Wnt5a/ROR1 signaling pathway.” In this editorial, researchers Kamrul Hasan and Thomas J. Kipps from the University of California discuss cortactin—an intracellular cytoskeletal protein that can undergo tyrosine phosphorylation upon external stimulation and promote polymerization and the assembly of the actin filament that is required for cell migration. Upon stimulation, cortactin ...

Male beetles face a trade-off between competing with other males for mating opportunities and repairing damage to their sperm DNA, according to a study publishing April 4th in the open access journal PLOS Biology by Mareike Koppik from Uppsala University, Sweden, and colleagues. Mutations in sperm and egg DNA can reduce the survival and fitness of offspring, so animals use a variety of repair and maintenance mechanisms in their reproductive cells. However, previous research has shown that sperm DNA has more mutations than egg DNA in a variety of ...

The prevalence of multimorbidity, the co-occurrence of two or more chronic conditions, varies depending on exactly how it is defined. And the healthcare costs associated with many disease combinations cost more together than the sum of each individual disease. Those are the conclusions of two new studies, publishing April 4th in the open access journal PLOS Medicine, that broadly analyze the concept and costs of multimorbidity. Multimorbidity is increasing in prevalence due to improved survival from chronic diseases and population aging, and now poses major challenges to healthcare systems worldwide. ...

CAMBRIDGE, MA -- Materials known as metal-organic frameworks (MOFs) have a rigid, cage-like structure that lends itself to a variety of applications, from gas storage to drug delivery. By changing the building blocks that go into the materials, or the way they are arranged, researchers can design MOFs suited to different uses. However, not all possible MOF structures are stable enough to be deployed for applications such as catalyzing reactions or storing gases. To help researchers figure out which MOF structures might work best for a given application, MIT researchers have developed a computational approach that allows ...

Sexual selection provides an answer to the existence of lavishly ornate signals in animals, but not to the question of why such signals are attractive, why do females prefer the extravagant plumage of peacocks? As part of an international team, researchers at Eötvös Loránd University (ELTE) have shown that the reason is not the presumed wasteful cost of ornaments, as honest signals need not have to be costly at all as long as cheaters would have to pay to fake them. Researchers have developed a general formula to calculate honest equilibrium in any model, independent of the cost ...

RIVERSIDE, Calif. -- A University of California, Riverside, study has identified the biological underpinnings of a reproductive disorder caused by the mutation of a gene. This gene mutation also causes Fragile X Syndrome, a leading genetic cause of intellectual impairment and autism. The researchers found mutations of the Fragile X messenger ribonucleoprotein 1 gene, or FMR1, contribute to premature ovarian failure, or POF, due to changes in neurons that regulate reproduction in the brain and ovaries. The mutation has been associated with early infertility, due ...

PHILADELPHIA — Chronic kidney disease (CKD) is a strong cardiovascular risk factor and is often accompanied by hypertension and diabetes. Despite the disease’s prevalence—10 percent of individuals across the globe suffer from CKD—there are limited tools for measuring cardiac risk for CKD patients, until now. A new proteomic risk model for cardiovascular disease was found to be more accurate than current methods of measuring cardiac risk, according to a new study led by researchers in the Perelman School of Medicine at the University of Pennsylvania. The study published today in the European Heart Journal. The Penn researchers developed ...

How Little-Known Brain Cells Tamp Down Overexcited Neurons During Acute Stress A brimming inbox on Monday morning sets your head spinning. You take a moment to breathe and your mind clears enough to survey the emails one by one. This calming effect occurs thanks to a newly discovered brain circuit involving a lesser-known type of brain cell, the astrocyte. According to new research from UC San Francisco, astrocytes tune into and moderate the chatter between overactive neurons. This new brain circuit, described March 30, 2023 in Nature Neuroscience, plays a role in modulating attention and perception, and may hold a key to treating attention disorders like ...

Worcester, Mass. – April 4, 2023 – WPI Researcher Kristen Billiar has been awarded $429,456 from the National Institutes of Health to investigate how stretching and blood flow can inhibit or encourage cardiovascular cells to populate and grow in tissue-engineered heart valves. The three-year project focuses on experimental valves that are not yet used in humans, and the work will expand understanding about how mechanical forces propel cells in the body. “Existing heart valves have drawbacks, ...

Articles Disclosing Conflicts of Interest to Potential Research Participants: Good for Nothing? Inmaculada de Melo-Martín The growing commercialization of science has raised concerns about financial conflicts of interest. Evidence suggests that such conflicts threaten the integrity of research and the well-being of research participants. Trying to minimize these negative effects, federal agencies, academic institutions, and publishers have developed conflict-of-interest policies. Among such policies, recommendations or requirements to disclose financial COIs to potential research participants ...

In criminal justice, public belief in redeemability reduces punitiveness and increases support for policy measures like rehabilitation, expungement, and housing and employment opportunities. In a new study, researchers examined the effects of racial attitudes on redeemability—the belief that offenders can change and go on to lead law-abiding lives. Belief in redeemability was high for offenders in general as well as for Black offenders, but White nationalism reduced White people’s beliefs in the redeemability of Black offenders. The study was conducted by Leah C. Butler, incoming assistant professor of criminal justice at the University ...
