People who have survived cancer as children are at higher risk of developing severe COVID-19, even decades after their diagnosis. This is shown by a new study from Karolinska Institutet published in the journal The Lancet Regional Health – Europe. Thanks to medical advances, more and more children are surviving cancer. However, even long after treatment has ended, health risks may remain. In a new registry study, researchers investigated how adult childhood cancer survivors in Sweden and Denmark were affected by the COVID-19 pandemic. The ...

New research has revealed alarming coral mortality rates of 92 per cent after last year’s bleaching event at Lizard Island on Queensland’s Great Barrier Reef, marking one of the highest coral mortality rates ever documented globally.   The team assessed the impact of the Fourth Global Coral Bleaching Event, declared by the National Oceanic and Atmospheric Administration (NOAA) in April 2024, which caused extensive bleaching and mortality across the reef system.  Lead author Dr Vincent Raoult from Griffith University’s School of Environment, ...

Researchers at Zhejiang University School of Medicine have identified a single point mutation in the normal PML gene that can block the effect of arsenic trioxide, a frontline drug for acute promyelocytic leukemia. This discovery uncovers a hidden cause of treatment failure and suggests a new target for genetic screening in relapsed patients. This work addresses the urgent issue of why some patients relapse despite a therapy that otherwise greatly improves survival. Mutation Explains Why a Small Portion of Leukemia Patients Relapse on Arsenic Therapy Arsenic trioxide cures most acute promyelocytic leukemia patients, but some patients relapse without an ...

The future of smashed avocado might depend on patches of native vegetation preserved alongside farmland, as new Curtin research reveals the hidden role of these habitats in supporting the insects that keep crops - and brunch menus - thriving. The research, published this week, found that insect communities in avocado orchards adjacent to native remnant vegetation foraged on more than twice as many plant species at times when crop flowering was limited, compared to those in orchards bordered by pasture. Insects with more diverse food sources are more likely to survive and pollinate crops so this finding offers a potential clue to safeguarding ...

University of Sydney researchers have harnessed human-made lightning to develop a more efficient method of generating ammonia – one of the world’s most important chemicals. Ammonia is also the main ingredient of fertilisers that account for almost half of all global food production. The team have successfully developed a more straightforward method to produce ammonia (NH3) in gas form. Previous efforts by other laboratories produced ammonia in a solution (ammonium, NH4+), which requires more energy and processes to transform it into the final gas product. The current method to generate ammonia, the Haber-Bosch process, comes at great ...

Some of the most encouraging results for reaction-enhancing catalysts come from one material in particular: tin (Sn). While Sn's overall utility as a catalyst is well-known, its underlying structure-performance relationship is poorly understood, which limits our ability to maximize its potential. To address this knowledge gap, researchers at Tohoku University's Advanced Institute for Materials Research (WPI-AIMR) used machine learning to characterize Sn catalyst activity. The highly accurate simulations could be a game-changer that helps researchers swiftly and simply ...

Physician associates provide safe and effective care when they work under the direct supervision of doctors and care for patients who have already been diagnosed, or when they undertake procedures for which they have been highly trained, finds a rapid review published in The BMJ today. However, the rapid review on the safety and effectiveness of physician associates found insufficient evidence to support them assessing undiagnosed patients under indirect supervision—when seeing undiagnosed patients in primary care, for example. Patient satisfaction levels ...

The more we interact with robots, the more human we perceive them to become – according to new research from the University of East Anglia. It may sound like a scene from Blade Runner, but psychologists have been investigating exactly what makes robot interactions feel more human. A new paper published today reveals that playing games with robots to ‘break the ice’ can help bring out their human side. The research team say that the implications are significant for the future of robotics. As robots take on roles from care-giving to customer service, designing interactions that promote social engagement ...

Individual expectations about one's health can influence him/her future condition and the speed of the progression of a disease: in fact, a research conducted by researchers of psychology at the Università Cattolica del Sacro Cuore, Milan campus, shows that, after a diagnosis of asthma, people who are optimistic about their health will have a slower progression of the disease. The study was published in the journal Health Expectations (Wiley) and conducted by full Professor Francesco Pagnini of the Department of Psychology at the Università Cattolica and colleagues. Professor Pagnini explains: “this study was developed in response to ...

When surgeons dissect tissue to remove a tumor or make a repair they must work cautiously, relying on electrophysical monitors and their own anatomical knowledge to avoid cutting nerves, which could complicate the patient’s recovery. A University of New Mexico surgeon has helped develop and test a first-of-its-kind drug that binds to nerve tissue and fluoresces – emits light – enabling surgeons to better see the nerves they’re trying to work around. A newly published study in Nature Communications ...

The study, conducted by a team of researchers from the University of Chinese Academy of Sciences and Chongqing Medical University, has established a prognostic model that links EMP1 expression with adverse clinical outcomes, particularly among older PC patients.   Pancreatic cancer remains a highly aggressive ...

  A recent study published in Genes & Diseases reveals a novel role of XPR1 in promoting ovarian cancer growth by regulating autophagy and MHC-I expression. The research, conducted by scientists from Chongqing Medical University, identifies XPR1 as a critical factor influencing the aggressiveness of ovarian cancer through its interaction with LAMP1 and the PI3K/Akt/mTOR signaling pathway. These findings shed light on new therapeutic targets for ovarian cancer, a malignancy known for its poor prognosis and resistance to immune checkpoint inhibitors.   The ...

CLEVELAND—Researchers at Case Western Reserve University have developed an environmentally safer type of plastic that can be used for wearable electronics, sensors and other electrical applications. The material, a so-called ferroelectric polymer, is made without fluorine, considered a “forever” chemical that hurts the environment because compounds made with it don’t break down quickly or at all. Although the researchers are still working to improve the material’s electric and elastic properties, the potential is vast for its flexibility of electronic uses and eco-friendly structure. “How this material ...

Key takeaways Researchers from Penn and Arizona State University pinpoint a lone five-particle package (a 5-plet) that could upend string theory by detecting it at the Large Hadron Collider. “Ghost” tracks that vanish mid-flight may be the smoking gun physicists are chasing. Early data squeeze the search window, but the next collider runs could make—or break—the case. In physics, there are two great pillars of thought that don’t quite fit together. The Standard Model of particle physics describes all known fundamental particles and three forces: electromagnetism, ...

While the emergence of multiple options for non-invasive respiratory support has revolutionized care in such cases, selecting the optimal approach remains difficult. Now, a special issue from the Journal of Intensive Medicine titled “Non-invasive respiratory support for acute hypoxemic respiratory failure” provides key insights to guide these critical treatment decisions. This collection establishes a robust foundation for understanding the key respiratory support ...

LA JOLLA, CA—A new study, published recently in Nature Communications, offers the first-ever map of which parts of Chikungunya virus trigger the strongest response from the body's T cells.  With this map in hand, researchers are closer to developing Chikungunya vaccines or therapies that harness T cells to strike specific targets, or "epitopes," to halt infection. The new study also offers important clues for understanding why many people experience chronic, severe joint pain for years after clearing the virus. "Now we can see what T cells are seeing patients with chronic disease," says LJI Assistant Professor ...

  New discoveries from the Pleistocene-age Gantangqing site in southwestern China reveal a diverse collection of wooden tools dated from ~361,000 to 250,000 years ago, marking the earliest known evidence of complex wooden tool technology in East Asia. The findings reveal that the Middle Pleistocene humans who used these tools crafted the wooden implements not for hunting, but for digging and processing plants. Although early humans have worked with wood for over a million years, wooden artifacts are quite rare in the archaeological ...

Ecologists are concerned that forest ecosystems will not keep pace with a rapidly changing climate, failing to remain healthy and productive. Before the rapid climate change of the past century, tree populations in the Northern Hemisphere adapted to colder and warmer periods over thousands of years. During onsets of Ice Ages, tree populations migrated south, seeking warmer conditions as global temperatures cooled, their seeds dispersed by winds and carried by animals. When the climate warmed again, tree species adapted by migrating north to more suitable conditions. Mature trees are long-lived, and their populations can’t migrate quickly. Current climate change ...

Ecologists celebrated the release of thousands of palm-sized lake sturgeon into northwest Ohio's Maumee River in 2018, kicking off an ambitious two-decade plan to re-establish the ancient species in the waters it once called home. More than five years later, it’s still too soon to declare success. But early signs are promising, according to recent research led by The University of Toledo and published in the peer-reviewed North American Journal of Fisheries Management. The research tracked the first-year survival rates for cohorts released in 2018, 2019 and 2021, with results suggesting that the initiative is on track to achieve its goal of a self-sustaining ...

CAMBRIDGE, MA -- Incoming information from the retina is channeled into two pathways in the brain’s visual system: one that’s responsible for processing color and fine spatial detail, and another that’s involved in spatial localization and detecting high temporal frequencies. A new study from MIT provides an account for how these two pathways may be shaped by developmental factors. Newborns typically have poor visual acuity and poor color vision because their retinal cone cells are not well-developed at birth. This means that early in life, they are seeing blurry, color-reduced imagery. The MIT team proposes that such blurry, color-limited ...

Scientists have found evidence that the Asian continent was free of permafrost all the way to its northerly coast with the Arctic Ocean when Earth’s average temperature was 4.5˚C warmer than today, suggesting that the whole Northern Hemisphere would have also been free of permafrost at the time. The stark findings indicate that if average global temperatures were to rise by this amount in the future, permafrost found in the Northern Hemisphere today would thaw. Such a temperature increase would release up to 130 billion tonnes of carbon currently frozen in the ground over the coming decades. The ...

New Haven, Conn. — Cancer fighting T-cells, the immune system’s primary enforcers, are scarce in the rare kidney cancer called chromophobe renal cell carcinoma (ChRCC) and those that are present are indifferent to the tumor threat and traditional immune therapies, revealing the need for new targets and treatments.   Those are among the results described in a July 2 published report in the Journal of Clinical Oncology that set out to understand the biology of certain kidney tumors, including ChRCC, and their immune responses.   The study found that ChRCC, which accounts ...
