New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London and City University New York, published today (Wednesday 5 July) in JAMA Psychiatry, has found that the way childhood abuse and/or neglect is remembered and processed has a greater impact on later mental health than the experience itself. The authors suggest that, even in the absence of documented evidence, clinicians can use patients’ self-reported experiences of abuse and neglect to identify those at risk of developing mental health difficulties ...

DALLAS (SMU) – A large formation of granite discovered below the lunar surface likely was formed from the cooling of molten lava that fed a volcano or volcanoes that erupted early in the Moon’s history – as long as 3.5 billion years ago. A team of scientists led by Matthew Siegler, an SMU research professor and research scientist with the Planetary Science Institute, has published a study in Nature that used microwave frequency data to measure heat below the surface of a suspected volcanic ...

We interact with bits and bytes everyday – whether that’s through sending a text message or receiving an email.    There’s also quantum bits, or qubits, that have critical differences from common bits and bytes. These photons – particles of light – can carry quantum information and offer exceptional capabilities that can’t be achieved any other way. Unlike binary computing, where bits can only represent a 0 or 1, qubit behavior exists in the realm of quantum mechanics. Through “superpositioning,” a qubit can represent a 0, ...

Researchers using NASA’s James Webb Space Telescope have made major strides in confirming the source of dust in early galaxies. Observations of two Type II supernovae, Supernova 2004et (SN 2004et) and Supernova 2017eaw (SN 2017eaw), have revealed large amounts of dust within the ejecta of each of these objects. The mass found by researchers supports the theory that supernovae played a key role in supplying dust to the early universe. Dust is a building block for many things in our universe – planets in particular. As dust from dying stars spreads through space, it carries essential elements to help give birth to the next generation of stars ...

Danish researchers solve the mystery of how deadly virus hide in humans With a new method for examining virus samples researchers from the University of Copenhagen have solved an old riddle about how Hepatitis C virus avoids the human body's immune defenses. The result may have an impact on how we track and treat viral diseases in general. An estimated 50 million people worldwide are infected with with chronic hepatitis C. The hepatitis C virus can cause inflammation and scarring of the liver, and in the worst case, liver cancer.   Hepatitis C was discovered in 1989 and is one of the most studied viruses on the planet. Yet for decades, how it manages to evade the human immune ...

A study of the genetic variation that makes mice more susceptible to bowel inflammation after a high-fat diet has identified candidate genes which may drive inflammatory bowel disease (IBD) in humans. The findings are published as a Reviewed Preprint in eLife. Described by the editors as a fundamental study, the work provides a framework for using systems genetics approaches to dissect the complex mechanisms of gut physiology. The authors show how it is possible to use genetically diverse but well-characterised mice to interrogate intestinal inflammation and pinpoint genes influenced by the environment ...

Most people have at some point in their life suffered an intestinal infection or food poisoning forcing them to stay close to the bathroom. It is very uncomfortable. Most of the time, though, it passes quickly. But around 60,000-100,000 Danes suffer from a form of chronic diarrhoea called bile acid malabsorption or bile acid diarrhoea. It is a chronic condition characterised by frequent and sudden diarrhoea more than 10 times a day. Even though the disease is not life-threatening, it can seriously ...

PULLMAN, Wash. -- Kenyan patients who spend more than three days in the nation’s hospitals are more likely to harbor a form of bacteria resistant to one of the most widely used antibiotic classes, according to a recent study led by Washington State University. The research team found that 66% of hospitalized patients were colonized with bacteria resistant to third-generation cephalosporins, compared to 49% among community residents. Third-generation cephalosporins are typically used for serious infections, and resistance to these antibiotics ...

PITTSBURGH, July 5, 2023 — Children taking a prescription stimulant to manage symptoms of attention deficit hyperactivity disorder (ADHD) do not have more substance use or substance use disorder (SUD) as adolescents or young adults, according to a new study by researchers at the University of Pittsburgh School of Medicine. Published today in JAMA Psychiatry, the study may provide some reassurance to parents and clinicians who may be hesitant to prescribe ADHD stimulant medications for fear that they may lay the ...

“Listen, if there's one thing the history of evolution has taught us is that life will not be contained. Life breaks free. It expands to new territories, and it crashes through barriers painfully, maybe even dangerously, but . . . life finds a way,” said Ian Malcolm, Jeff Goldblum's character in Jurassic Park, the 1993 science fiction film about a park with living dinosaurs. You won't find any Velociraptors lurking around evolutionary biologist Jay T. Lennon's lab; however, Lennon, ...

-With pictures- In a new study, a group of scientists argue that the new high precision radiocarbon-based date set for Laacher See volcano eruption of 13,000 years before present is probably not correct. They argue that the correct age of the Laacher See volcano eruption is 12,880 years ago, 130 years after the date presented by Reinig et al., in 2021. The research team, which included scientists from Durham University, University of Oxford, Royal Holloway University of London, SYSTEMIQ Ltd. and Teesside University ...

CAMBRIDGE, MA — Engineering T cells to destroy cancer cells has shown success in treating some types of cancer, such as leukemia and lymphoma. However, it hasn’t worked as well for solid tumors. One reason for this lack of success is that the T cells target only one antigen (a target protein found on the tumors); if some of the tumor cells don’t express that antigen, they can escape the T cell attack. MIT researchers have now found a way to overcome that obstacle, using a vaccine that boosts the response of ...

About The Study: Cannabis use disorder was associated with a modest increased risk of perioperative morbidity and mortality after major elective, inpatient, noncardiac surgery. In the context of increasing cannabis use rates, these findings support preoperative screening for cannabis use disorder as a component of perioperative risk stratification. However, further research is needed to quantify the perioperative impact of cannabis use by route and dosage and to inform recommendations for preoperative cannabis cessation. Authors: Paul P. ...

About The Study: This study found that Black patients’ experiences with racism, specifically epistemic injustice, were associated with their perspectives on medical care and decision making during serious illness and end of life. These findings suggest that race-conscious, intersectional approaches may be needed to improve patient-clinician communication and support Black patients with serious illness to alleviate the distress and trauma of racism as these patients near the end of life. Authors: Crystal ...

About The Study: Assessing the association of well-being and cardiovascular outcomes, higher well-being, a measurable, modifiable, and meaningful outcome, was associated with lower cardiovascular disease mortality, even after controlling for structural and cardiovascular-related population health factors, indicating that well-being may be a focus for advancing cardiovascular health.

New research by the University of Liverpool could signal a step change in the quest to design the new materials that are needed to meet the challenge of net zero and a sustainable future. Publishing in the journal Nature, the Liverpool researchers have shown that a mathematical algorithm can guarantee to predict the structure of any material just based on knowledge of the atoms that make it up. Developed by an interdisciplinary team of researchers from the University of Liverpool’s Departments of Chemistry and Computer Science, the algorithm systematically evaluates entire sets of possible structures at once, rather than considering them one at a time, to accelerate identification ...

Bicuspid aortic valve is the most common congenital defect in humans, affecting between 1% and 2% of the population. Instead of the usual three symmetric leaflets, affected individuals have two asymmetric valve leaflets. This defect is a frequent cause of aortic stenosis and endocarditis and is associated with early calcification of the aortic valve. Currently the only effective treatment is valve replacement surgery. But this situation could be changed by the results of a new study published by an international team co-led by CNIC group leader Dr. José ...

Detailed analysis of data obtained by the Zhurong rover of dunes located on the southern Utopian Plain of Mars suggests the planet underwent a major shift in climate that accompanied changes in prevailing winds. This shift likely occurred about 400,000 years ago, which coincides with the end of the last glacial period on Mars. Researchers from the National Astronomical Observatories, Institute of Geology and Geophysics and Institute of Tibetan Plateau Research of the Chinese Academy of Sciences, in collaboration with colleagues from Brown University, assessed the surface structure and chemical composition of Martian dunes to ...

A new study on the coexistence of bacteria and fungi shows that a mutually beneficial, functioning symbiosis can be very fragile. Researchers at the Leibniz Institute for Natural Product Research and Infection Biology (Leibniz-HKI) in Jena found out that the bacterial species Mycetohabitans rhizoxinica lives happily in the hyphae of the fungus Rhizopus microsporus only when the bacteria produce a certain protein. In a symbiosis, two organisms join together and benefit from each other; in endosymbiosis, one of ...

CAMBRIDGE, MD (July 5, 2023)—Researchers have found that one method of reducing greenhouse gas emissions is available, affordable, and capable of being implemented right now. Nitrous oxide, a potent greenhouse gas and ozone-depleting substance, could be readily abated with existing technology applied to industrial sources. “The urgency of climate change requires that all greenhouse gas emissions be abated as quickly as is technologically and economically feasible,” said lead author Eric Davidson, a professor with the University of Maryland Center for Environmental ...

Tumor-initiating cells, or cancer stem cells, are gaining attention in cancer therapy, as they can travel through the body and cause cancerous tumors at other sites through metastasis. These cells also may cause resistance to chemotherapy. Pancreatic ductal adenocarcinoma (PDAC) is a type of cancer that has a poor prognosis. The problem of metastasis is particularly prominent in this type of cancer. Though the tumor-initiating cells are implicated in the disease progression of some cancers, their specific role, unique traits, and the underlying signaling pathways of their action in pancreatic adenocarcinoma remain poorly understood. ...

WASHINGTON (July 5, 2023) – A new multicenter, single-arm, open-label study is the first to exclusively assess bleeding complications in patients undergoing high-risk percutaneous coronary interventions (PCI) with Impella with independent adjudication via a clinical events adjudication committee and will gather meaningful real-world data based on contemporary practice. The design and rationale of the study was published online today in the Journal of the Society for Cardiovascular Angiography & Interventions (JSCAI). Nearly one in every five patients1 will experience a bleeding complication during a large-bore endovascular procedure. Periprocedural ...
