A preclinical evaluation of a new ’dual-mode’ tracer agent shows promise in not only helping surgeons image and plan prostate cancer procedures, but also provide them with much more consistent and targeted guidance during surgery. The agent uses a single tracer molecule labeled with Fluorine-18—a common isotope used in Positron Emission Tomography (PET) scans—for diagnostic imaging. It also provides a one-step, widely accessible solution that would enable combined fluorescence-guided and radio-guided surgery. “Precision ...

Most of the drugs, plastics, and industrial materials widely used today are produced through chemical reactions. In general, most high-performance and sophisticated substances have complex structures, and their assembly involves multiple chemical reaction steps carried out one after another. This creates significant overhead, as each step requires specific conditions, reagents, and catalysts, as well as considerable energy and labor. Tandem reactions offer a promising solution to this issue. The ...

A new critical review, published in the journal CABI Agriculture and Bioscience, highlights the emergence and scientific basis of regenerative agriculture – proposing a working definition centred on ecological cycles and farm system outcomes. Dr Nicholas Bardsley, author of the paper from the Department of Agri-Food Economics and Marketing at the University of Reading, suggests that as global agriculture faces intensifying soil degradation, climate disruption, and ecological breakdown, there ...

Researchers at the Complexity Science Hub (CSH) analyzed 13 million inpatient hospital stays involving around 4 million individuals in Austria: Although about 20% of the population in Austria does not hold Austrian citizenship, this group accounts for only 9.4% of hospital patients and 9.8% of total hospital nights. An estimated 300 million people – about 3.6 percent of the global population – are international migrants. Yet studies consistently show that migrants access healthcare services less frequently ...

PITTSBURGH, Aug. 21, 2025 – New research from the University of Pittsburgh School of Medicine and Cambridge University upends a long-standing belief about brain plasticity. A study published today in Nature Neuroscience shows that the brain’s built-in “body map” remains stable even when the body undergoes drastic changes, such as the loss of a limb. The findings have implications for the treatment of “phantom limb” pain and suggest that achieving reliable restoration of sensation and controlling robotic replacement limbs via brain-computer interfaces may be more viable in the long term than previously thought. “This study is a powerful ...

Research Highlights: Hormone replacement therapy using vaginal estrogen tablets was not associated with an increased risk of ischemic stroke for postmenopausal women who have already had a stroke, according to a data analysis from a health registry in Denmark. This is one of the first studies to analyze the risk of recurrent stroke for postmenopausal women using vaginal estrogen. Embargoed until 4 a.m. CT/5 a.m. ET, Thursday, August 21, 2025 DALLAS, August 21, 2025 — Using vaginal estrogen ...

GLOBAL: Australian researchers have used an innovative genome-wide screening approach to identify genes, and their encoded proteins, that play critical roles in the prevention of lymphoma development, revealing new potential treatment targets for these blood cancers.  The study, published in Nature Communications today, has identified a group of proteins known as the GATOR1 complex as essential tumour suppressors.   The GATOR1 complex normally functions as a ‘brake’ on cellular growth by regulating pathways that control cell growth and metabolism.1 When GATOR1 components are lost or defective, this protective mechanism ...

To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate. Scientists encode these building blocks of quantum information to suppress errors in other qubits so that a minority can operate in a way that produces useful outcomes. As the number of useful (or logical) qubits grows, the number of physical qubits required grows even further. As this scales up, the sheer number of qubits needed to create ...

UNIVERSITY PARK, Pa. — If an extraterrestrial intelligence were looking for signs of human communications, when and where should they look? In a new study, researchers at Penn State and NASA’s Jet Propulsion Laboratory in Southern California analyzed when and where human deep space transmissions would be most detectable by an observer outside our solar system and suggest that the patterns they see could be used to guide our own search for extraterrestrial intelligence (SETI). “Humans are predominantly communicating with the spacecraft and probes we have ...

University of Arizona researchers devised a new method to deliver cancer chemotherapy drugs to pancreatic and breast cancer tumors more effectively and with less damage to healthy tissues than standard forms of chemotherapy. The paper was published today in Nature Cancer. The research team’s new formulation of the drug paclitaxel may help overcome some common limitations of chemotherapy drugs, setting the stage for a promising new platform for treating cancer and other diseases. “Paclitaxel is potent and kills cancer cells, but to unleash its full therapeutic potential, we have to address its toxicity,” ...

In a first-of-its-kind study, researchers found that the brain’s control center for a lost appendage can persist long after surgical amputation, which stands in stark contrast to longstanding theories about the brain’s ability to reorganize itself, also known as plasticity. Scientists from the National Institutes of Health (NIH) and their colleagues examined human brain activity before and after arm amputation and found that the loss of a limb does not prompt a large-scale cerebral overhaul. Published in the journal Nature Neuroscience, ...

Heat-stressed Victorian mountain ash forests are thinning fast, turning from carbon sinks to carbon sources, new research reveals. Published in Nature Communications, the research shows forests will lose a quarter of their trees by 2080 due to global warning. Mountain ash forests are currently one of Earth’s most effective ecosystems for storing carbon – they store more carbon per hectare than the Amazon. But researchers say these forests will store less carbon in the future as warming causes more trees to die and decompose. Scientists from the Universities of Melbourne and ...

A deeper look into carbon flux is now possible — thanks to a deep pool of scientific collaboration. And for once, the spotlight is on Asia. Led by researchers at Osaka Metropolitan University, a collaborative team of researchers from Japanese institutions has introduced JapanFlux2024, the first large-scale open dataset of its kind for Asia. It details how terrestrial ecosystems across Japan and neighboring regions absorb and release carbon dioxide (CO2), offering a long-awaited foundation for understanding Asia’s role in the global carbon cycle. Across Asia’s diverse landscapes—from ...

LGBTQIA+ college students living in conservative US states have reported far worse mental health than their counterparts in more liberal areas in a national study. Analysis of a survey—carried out prior to the latest Republican term—uncovered this group, who fell within an age bracket of 18 to 25, were considerably more likely to describe themselves as being anxious, depressed, and suicidal. The new report, published today in the Journal of American College Health, also revealed LGBTQIA+ students in conservative states were also more likely to feel afraid that something ...

With climate change and more frequent extreme weather events, researchers predict that global yields of important crops like maize, rice, and soybeans could decline by 12 to 20% by the end of the century. To prepare, plant scientists are hoping to find ways to improve yields and grow hardier varieties of these crops. New insights into the genetic makeup of wild varieties of common crops show how domestication has changed crop traits over time and propose a new cultivation method to improve genetic diversity. The research was shared in a paper published in Life on July 11. “While domesticated species have originally been bred by cultivating wild species, the resulting reduction in genetic ...

RIVERSIDE, Calif. -- When companies are acquired, conventional wisdom suggests that employee nostalgia for their pre-buyout days is a problem to be eliminated so workers can more quickly adapt to the new owners’ ways of doing business. A new study published in the journal Strategic Organization led by UC Riverside School of Business professors Boris Maciejovsky and Jerayr Haleblian suggests this thinking is wrong—especially when the new owners want to retain the most talented, productive, and informed workers. Nostalgia, they found, serves as a comforting and stabilizing force during takeover periods, when employees feel vulnerable, fear ...

Individuals should be held accountable for “ecocide,” the most serious acts of environmental destruction, argue experts in The BMJ today. And they say the UK should take on a leadership role by adopting legislation of its own to criminalise ecocide and inspiring other nations to protect our planet. The term “ecocide” was coined in 1970 by biologist Arthur Galston, who condemned the large scale environmental devastation caused during the Vietnam War, they explain. Fifty years on, as the world grapples with the escalating consequences of climate change, including sea level rises and biodiversity ...

Many direct to consumer menopause services are unnecessary and do not improve care, warn experts in The BMJ today. They argue that the sharp rise in commercial services for women seeking relief for menopausal symptoms raises concerns about the reliability and potential commercial bias of the information, and that symptoms are best assessed by a thorough clinical history with treatment decisions guided by clinical response and patient preferences. One of the most troubling trends arising from this surge is the promotion of routine ...

Parents are spending thousands of pounds to bank stem cells from their children’s milk teeth – but the recipient companies’ claims about their future medical value are unproven and potentially misleading, reveals an investigation by The BMJ, published today. The companies’ claims include that stem cells banked from teeth are already being used in treatments for autism and diabetes. They also highlight current research using stem cells in multiple sclerosis, Parkinson’s disease, and heart attacks. Tooth stem cell ...

The world will warm more than expected due to future changes in ozone, which protects Earth from harmful sun rays but also traps heat as it is a greenhouse gas.  While banning ozone-destroying gases such as CFCs has helped the ozone layer to recover, when combined with increased air pollution the impact of ozone could warm the planet 40% more than originally thought.   A new study led by the University of Reading found that from 2015 to 2050, ozone is expected to cause 0.27 watts ...

The complex 3D shapes of brains, lungs, eyes, hands, and other vital bodily structures emerge from the way in which flat 2D sheets of cells fold during embryonic development. Now, researchers at Columbia Engineering have developed a novel way to use light to influence an animal's own proteins in order to control folding in live embryos. These new findings, detailed Aug. 18 in Nature Communications, may one day lead to a host of applications in biorobotics and medical research. "Being able to precisely control the shape of folds in tissue sheets ...

In a towering aquarium in a darkened laboratory, moon jellyfish (Aurelia aurita) hover as if floating in space. The glow of neon lights illuminates their translucent, bell-shaped bodies as they expand and contract rhythmically, their graceful tentacles flowing in wavelike patterns. CU Boulder engineer Nicole Xu watches them with fondness. Xu, an assistant professor in the Paul M. Rady Department of Mechanical Engineering, first became fascinated with moon jellies more than a decade ago because of their ...

Atmospheric waves from a massive 2022 South Pacific volcanic eruption created seismic waves that penetrated Earth to at least 5 kilometers in Alaska, creating an opportunity to employ an unusual method of peering into the state’s deep subsurface. Ken Macpherson, a scientist at the University of Alaska Fairbanks Geophysical Institute, and other researchers analyzed the coupling of atmospheric pressure waves with the ground to determine the speed at which seismic waves travel through Alaska’s upper crust.  Subsurface material properties such as hardness, which controls seismic velocity, can ...
