SAN DIEGO, October 2, 2023 — A type of head and neck cancer predominantly diagnosed in people who reside in low- and middle-income countries may be treated effectively with fewer, but higher doses of radiation, a large new international study suggests. The study – a randomized phase III clinical trial involving 10 countries across four continents – found delivering a course of radiation in 20 rather than 33 treatment sessions was just as effective at controlling cancer for patients with alcohol and tobacco-related, locally advanced disease, without increasing side ...

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. Lead ...

About The Study: In this study of 6,866 individuals with COVID-19, nirmatrelvir and ritonavir (Paxlovid [Pfizer]) treatment was associated with reduced risk of COVID-19 hospitalization or death in clinically extremely vulnerable individuals, with the greatest benefit observed in severely immunocompromised individuals. No reduction in the primary outcome (death from any cause or emergency hospitalization with COVID-19 within 28 days) was observed in lower-risk individuals, including those age 70 or older without serious comorbidities.  Authors: Colin R. Dormuth, Sc.D., ...

People frequently exposed to racial or ethnic discrimination may be more susceptible to obesity and related health risks in part because of a stress response that changes biological processes and how we process food cues. These are findings from UCLA researchers conducting what is believed to be the first study directly examining effects of discrimination on responses to different types of food as influenced by the brain-gut-microbiome (BGM) system. The changes appear to increase activation in regions of the brain associated with reward and self-indulgence – like seeking “feel-good” ...

DURHAM, N.C. – Researchers at Duke University have demonstrated an app driven by AI that can run on a tablet to accurately screen for autism in children by measuring and weighing a variety of distinct behavioral indicators. Called SenseToKnow, the app delivers scores that evaluate the quality of the data analyzed, the confidence of its results and the probability that the child tested is on the autism spectrum. The results are fully interpretable, meaning that they spell out exactly which of the behavioral indicators led to its conclusions and why. This ability ...

New York, NY (October 2, 2023)—Mount Sinai investigators have developed a new approach for treating invasive bladder cancer without the need for surgical removal of the bladder, according to a study published in Nature Medicine in September. Removing the bladder is currently a standard approach when cancer has invaded the muscle layer of the bladder. In a phase 2 clinical trial that was the first of its kind, doctors found that some patients could be treated with a combination of chemotherapy and immunotherapy without the need to remove their bladder. ...

Researchers at the University of Cologne’s CECAD Cluster of Excellence for Aging Research and the CEPLAS Cluster of Excellence for Plant Sciences have found a promising synthetic plant biology approach for the development of a therapy to treat human neurodegenerative diseases, especially Huntington’s disease. In their publication “In-planta expression of human polyQ-expanded huntingtin fragment reveals mechanisms to prevent disease-related protein aggregation” in Nature Aging, they showed that a synthetic enzyme derived from plants – stromal processing peptidase (SPP) – reduces the clumping of proteins responsible for the pathological changes ...

CONTAGIOUS CANCERS IN COCKLES SEQUENCED, SHOWING UNEXPECTED INSTABILITY    Transmissible cancers in cockles — marine cancers that can spread through the water — have been sequenced for the first time, unearthing new insight into how these cancers have spread across animal populations for hundreds, possibly thousands, of years. The study, from researchers at the Wellcome Sanger Institute, the CiMUS research centre at the Universidade de Santiago de Compostela in Spain, and collaborators across multiple countries, found that these cockle tumours are highly genetically unstable. The cancer ...

Observations of the BlueWalker 3 prototype satellite show it is one of the brightest objects in the night sky, outshining all but the brightest stars. Astronomers have raised concerns that without mitigation, groups of large satellites could disrupt our ability to observe the stars from Earth and perform radio astronomy. Several companies are planning ‘constellations’ of satellites – groups of potentially hundreds of satellites that can deliver mobile or broadband services anywhere in the world. However, these satellites need to be in ‘low-Earth’ orbit and can be relatively large, ...

When two, three or four apples are placed in front of us, we are able to recognize the number of apples very quickly. However, we need significantly more time if there are five or more apples and we often also guess the wrong number. In fact, the brain does actually register smaller numbers of things differently than larger ones. This has been demonstrated in a recent study by the University of Tübingen, University of Bonn and the University Hospital Bonn. The results were published in the magazine Nature ...

In a groundbreaking study published in JAMA Pediatrics on October 2, 2023, researchers at Boston Children’s Hospital shed new light on the evolving nature of Autism Spectrum Disorder (ASD) diagnoses in early childhood. Diagnosing ASD at a young age is important for early intervention and treatment, but this new study suggests that not all kids continue to meet the criteria for ASD as they get older. The team found that 37% of children diagnosed with ASD as toddlers no longer meet the criteria for ASD around the age of six. Children with lower adaptive skills—essential everyday abilities encompassing communication, self-care, and decision-making—tend ...

Vulnerable coastlines  Unfortunately, precisely in these rural densely populated Asian regions, mangroves have in the past been cleared to free up land for other uses such as aquaculture. This has made these coasts vulnerable to rapid erosion. Restoring mangroves seems a logical solution to reverse this process and protect these densely populated coastlines. However, this requires understanding if mangroves can cope with extreme rates of relative sea level rises, as experienced in these subsiding areas. Since 2015 NIOZ researcher Celine van Bijsterveldt visited Indonesia regularly during her studies and her Phd. ...

Using a new analysis method for satellite images, an international research team, coordinated by the French Alternative Energies and Atomic Energy Commission (CEA) and INRAE, mapped for the first time annual changes in global forest biomass between 2010 and 2019. Researchers discovered that boreal and temperate forests have become the main global carbon sinks. Tropical forests, which are older and degraded by deforestation, fire and drought, are nearly carbon neutral. The findings, published in Nature Geoscience, highlight the importance of accounting for young forests and forest ...

Subarachnoid haemorrhage (SAH) is one of the most dangerous cerebrovascular disorders, with as many as 40% of patients dying within one month of the event. A study recently published in the esteemed Neurology journal investigated whether there are differences in the prognosis of SAH patients between the university hospital districts in Finland. The research dataset was composed of nearly 10,000 SAH cases from 1998 to 2017, including information on patients who died before receiving neurosurgical care. Prognoses ...
