COLUMBUS, Ohio – Altered measles and mumps viruses could be used as a platform to create a trivalent COVID-19 vaccine that triggers immunity to multiple variant strains of the SARS-CoV-2 virus, new research in animals suggests. The study builds upon previous studies that involved inserting a highly stable segment of the coronavirus spike protein into the measles vaccine or mumps vaccine. In a paper publishing this week in Proceedings of the National Academy of Sciences, scientists at The Ohio State University report on a new MMS vaccine candidate – for Measles, ...

Researchers led by Giulia Galli at University of Chicago’s Pritzker School of Molecular Engineering report a computational study that predicts the conditions to create specific spin defects in silicon carbide. Their findings, published online in Nature Communications, represent an important step towards identifying fabrication parameters for spin defects useful for quantum technologies.  Electronic spin defects in semiconductors and insulators are rich platforms for quantum information, sensing, and communication applications. Defects are impurities and/or misplaced atoms in a solid and the electrons associated with these atomic defects carry ...

Mining brings huge social and environmental change to communities: landscapes, livelihoods and the social fabric evolve alongside the industry. But what happens when the mines close? What problems face communities that lose their main employer and the very core of their identity and social networks? A research fellow at the University of Göttingen provides recommendations for governments to successfully navigate mining communities through their transition toward non-mining economies. Based on past experiences with industrial transitions, she suggests that a three-step approach centred around stakeholder ...

SAN DIEGO, October 2, 2023 — A novel liquid biopsy test may help determine which patients with non-small cell lung cancer that has spread beyond the lungs are most likely to benefit from targeted, high-dose radiation, rather than drug-based therapy, a new study suggests. Findings will be presented today at the American Society for Radiation Oncology (ASTRO) Annual Meeting and published in npj Precision Oncology.  The study found that a liquid biopsy test – which identifies tumor DNA circulating ...

By Wynne Parry Laden with dissolved salt, Antarctic waters can hover just above freezing and even dip below it. Temperatures this low would likely kill the animals that prosper in warmer waters further north. Yet, some creatures have found ways to live in this inhospitable cold. In a new study described in Proceedings of the National Academy of Sciences, researchers at the Marine Biological Laboratory (MBL) and their collaborators focused on how life in such a frigid habitat has altered an enzyme essential ...

**Strictly embargoed until 20:00 (BST) Monday 2 October 2023** Scientists identify evolutionary gateway helping pneumonia bacteria become resistant to antibiotics     A new study from the University of Sheffield has revealed how pneumonia cells start to become resistant to penicillin antibiotics The effectiveness of antibiotics is increasingly under threat as the bacteria which cause pneumonia become more resistant to antibiotic treatment over time  The new research is a major step forward in helping scientists to better predict which ...

Scientists reveal new plant cell walls can have significantly different mechanical properties compared to surrounding parental cell walls, enabling cells to change their local shape and influence the growth of plant organs. This is the first time that scientists have related mechanics to cell wall “age” and was only made possible through a new method that follows the same cells over time and through successive rounds of division. The Cambridge researchers were able to see new walls forming and then measure their mechanical properties. This pioneering work showed that new cell walls in some plants are 1.5 times stiffer than the surrounding ...

Rapid identification of patients contaminated by “superbacteria” known as “carbapenem-resistant Enterobacteriaceae” (CRE), with early isolation of these patients, reduces transmission in hospital emergency departments. However, keeping them in the emergency room (ER) for more than two days undermines containment because it increases the risk of infection via colonization. These are the key findings of a study by a group at the University of São Paulo’s Medical School (FM-USP) in Brazil. An article on the study is published in the journal Clinical Infectious Diseases. Enterobacteria ...

MDMA, commonly known as ecstasy, is a recreational psychedelic drug often used at parties and dance clubs because it creates feelings of closeness and social connection with others. Because of this “empathogenic” effect, researchers are also interested in its potential use as a complement to traditional talk therapy. In fact, two recent successful clinical trials support the use of MDMA-assisted therapy as a treatment for post-traumatic stress disorder (PTSD). Researchers at the University of Chicago published a study in Scientific Reports on September 22, 2023, that looked more closely at the pharmacological ...

Survival rates for men with metastatic prostate cancer have increased by an average of six months, something which coincides with the gradual introduction of ‘dual treatment’ since 2016. This is according to a register study of all Swedish men diagnosed between 2008 and 2020. The results are published in the medical journal JAMA Network open. Dual treatment means that patients receive both standard hormone therapy (GnRH therapy) and chemotherapy or androgen receptor blockers. Research has previously shown that men receiving this treatment live approximately one year longer than those receiving GnRH treatment alone. “Dual treatment for men with newly diagnosed metastatic ...

A strategy for cellular reprogramming involves using targeted genetic interventions to engineer a cell into a new state. The technique holds great promise in immunotherapy, for instance, where researchers could reprogram a patient’s T-cells so they are more potent cancer killers. Someday, the approach could also help identify life-saving cancer treatments or regenerative therapies that repair disease-ravaged organs. But the human body has about 20,000 genes, and a genetic perturbation could be on a combination of genes or on any of the over 1,000 transcription factors that regulate the genes. ...

Let’s say you typically eat eggs for breakfast but were running late and ate cereal. As you crunched on a spoonful of Raisin Bran, other contextual similarities remained: You ate at the same table, at the same time, preparing to go to the same job. When someone asks later what you had for breakfast, you incorrectly remember eating eggs. This would be a real-world example of a false memory. But what happens in your brain before recalling eggs, compared to what would happen if you correctly recalled cereal? In a paper published in Proceedings ...

Photos Savannas and grasslands in drier climates around the world store more heat-trapping carbon than scientists thought they did and are helping to slow the rate of climate warming, according to a new study.   The study, published online Oct. 2 in Nature Climate Change, is based on a reanalysis of datasets from 53 long-term fire-manipulation experiments worldwide, as well as a field-sampling campaign at six of those sites.   Twenty researchers from institutions around the globe, including two at the University of Michigan, looked at where and why fire has changed the amount of carbon stored in topsoil. They found that within savanna-grassland regions, ...

A centuries-old technique for constructing arched stone windows has inspired a new way to form tailored nanoscale windows in porous functional materials called metal-organic frameworks (MOFs). The method uses a molecular version of an architectural arch-forming “centring formwork“ template to direct the formation of MOFs with pore windows of predetermined shape and size.[1]. New MOFs designed and made in this way range from narrow-windowed materials with gas separation potential to larger-windowed structures with potential medical applications due to their excellent oxygen-adsorption capacity. “One of the most challenging ...

DALLAS (SMU) – It’s long been understood that human settlement contributes to conditions that make Pacific Islands more susceptible to wildfires, such as the devastating Aug. 8 event that destroyed the Maui community of Lahaina. But a new study from SMU fire scientist Christopher Roos published in the journal Nature Ecology and Evolution shows that climate is an undervalued part of the equation. Roos, SMU environmental archaeologist and professor of anthropology, traveled with his team to the Sigatoka ...

Researchers at Helmholtz Munich and the Technical University of Munich have made significant progress in advancing high-resolution optoacoustic imaging for clinical use. Their innovative deep-learning framework, known as DeepMB, holds great promise for patients dealing with a range of illnesses, including breast cancer, Duchenne muscular dystrophy, and inflammatory bowel disease. Their findings have been now published in Nature Machine Intelligence. In order to understand and detect diseases scientists and medical staff often rely on imaging methods such as ultrasound or X-ray. However, ...

According to textbooks, proteins work by folding into stable 3D shapes that, like Lego blocks, precisely fit with other biomolecules. Yet this picture of proteins, the "workhorses of biology," is incomplete. Around half of all proteins have stringy, unstructured bits hanging off them, dubbed intrinsically disordered regions, or IDRs. Because IDRs have more dynamic, “shape-shifting” geometries, biologists have generally thought that they cannot have as precise of a fit with other biomolecules as their folded ...

Allowing eyewitnesses to dynamically explore digital faces using a new interactive procedure can significantly improve identification accuracy compared to the video lineup and photo array procedures used by police worldwide, a new study reveals. Interactive lineups present digital 3D faces that witnesses can rotate and view from different angles using a computer mouse - enabling witnesses to actively explore and match faces to their recollection. Publishing their findings today (2 Oct) in Proceedings of the National Academy of Sciences, psychologists found that the interactive procedure enhanced people’s ability to correctly identify perpetrators and avoid misidentifications.
