New research has shown hospital patients could reduce the carbon footprint and saturated fat content of their selected meals by up to almost a third – if the weekly menu featuring the same dishes is cleverly reorganised. The study, led by the University of Bristol, features in a special issue of the journal Philosophical Transactions of the Royal Society B, which sets out innovative ways to help make the UK’s food healthier, fairer, and more sustainable. The researchers developed a cunning way to redesign weekly set menus so healthier, greener dishes weren’t competing so much with typically more popular, less healthy options, boosting ...

Leuven, September 18, 2025 – VIB researchers and colleagues have discovered a mechanism through which melanoma cells adapt and switch between two major proliferative and invasive states, revealing promising new targets for cancer therapy. The study, published in Nature Metabolism, reveals that alterations in iron metabolism and organelle crosstalk are central to melanoma cell plasticity—a key factor in tumor progression and resistance to treatment. The changing face of melanoma Melanoma, one of the most aggressive skin cancers, often exhibits a remarkable ability to change its phenotype, enabling it to evade therapies and metastasize. While ...

Spintronics devices will be key to realizing faster and more energy-efficient computers. To give us a better understanding of how to make them, a Kobe University team now showed how different manufacturing techniques influence the material properties of a key component. Electronic devices could be made more efficient and faster if electrons could carry more information at once. This is the basic idea behind spintronics, where researchers try to use the electrons’ spin in addition to charge in data storage, processing and sensor devices to significantly improve our computers. ...

Researchers at the University of Gothenburg have made light-powered gears on a micrometer scale. This paves the way for the smallest on-chip motors in history, which can fit inside a strand of hair. Gears are everywhere – from clocks and cars to robots and wind turbines. For more than 30 years, researchers have been trying to create even smaller gears in order to construct micro-engines. But progress stalled at 0.1 millimetres, as it was not possible to build the drive trains needed to make them move any smaller. Researchers from Gothenburg University, among others, have now broken through this barrier by ditching ...

A study of migratory hoverflies on a North Sea oil rig has revealed their vital role as long-distance pollen transporters.    Researchers studied 121 marmalade hoverflies that landed on an oil rig in the Britannia oil field, 200km off the coast of Scotland. Pollen was found on 92% of the hoverflies and – with no vegetation on the rig, and no land nearby – this shows they can transport pollen over great distances, potentially linking plant populations that are hundreds of kilometres apart. The hoverflies ...

Philadelphia, September 18, 2025 – Researchers from Children’s Hospital of Philadelphia (CHOP) demonstrated how a multifaceted intervention approach significantly improved the rate of dental varnish applications to help strengthen tooth enamel and prevent decay. The results exceeded the goal for the study, and improvements were consistent across insurance plans, race and ethnicity, providing an important framework for keeping teeth healthy. The findings were published today in the journal Pediatrics. Dental fluoride varnish is a safe and effective procedure ...

The world of cells is surprisingly noisy. Each cell carries unique genetic information, but when we try to measure cellular activity, signals can be lost or blurred, and differences between experiments can further obscure the data. These challenges have made it difficult for researchers to capture the true behavior of cells, especially when studying rare cell types or subtle changes that appear in the early stages of disease. Take single-cell RNA sequencing as an example. It is a powerful technique for studying gene expression at the individual cell level, yet often encounters significant challenges due to two main types of noise: technical noise and batch noise. Technical ...

University of Warwick astronomers have uncovered the chemical fingerprint of a frozen, water-rich planetary fragment being consumed by a white dwarf star outside our Solar System.  In our Solar System, it is thought that comets and icy planetesimals (small solid objects in space) were responsible for delivering water to Earth. The existence of these icy objects is a requirement for the development of life on other worlds, but it is incredibly difficult to identify them outside our Solar System as icy objects are small, faint and require chemical   In ...

Regular Covid vaccinations should continue worldwide to reduce cardiac risks associated with the virus - according to new research from the University of East Anglia. A major report published today sets out ways of tackling the ‘profound and lasting impact’ of Covid and long Covid on cardiovascular health. It makes recommendations for diagnosing, treating and preventing serious heart and blood vessel complications linked to the virus. As well as continuing vaccination programmes, the report ...

Despite rising patient demand and commitments to strengthen primary care, one in three GPs with a licence to practise in England are not working in NHS general practice, finds a study published by The BMJ today. The results also suggest that many newly qualified GPs are not entering the NHS general practice workforce or are leaving within the first 10 years.  Overall, the number of patients for each full time equivalent GP in NHS general practice in England has risen by 15% since 2015. And by the end of 2024, there were twice as many NHS patients for ...

The Artificial Intelligence chatbot, ChatGPT, appeared to improvise ideas and make mistakes like a student in a study that rebooted a 2,400-year-old mathematical challenge. The experiment, by two education researchers, asked the chatbot to solve a version of the “doubling the square” problem – a lesson described by Plato in about 385 BCE and, the paper suggests, “perhaps the earliest documented experiment in mathematics education”. The puzzle sparked centuries of debate about whether knowledge is latent within us, waiting to be ‘retrieved’, or ...

BUFFALO, N.Y. — Tiny solid particles – like pollutants, cloud droplets and medicine powders – form highly concentrated clusters in turbulent environments like smokestacks, clouds and pharmaceutical mixers. What causes these extreme clusters – which make it more difficult to predict everything from the spread of wildfire smoke to finding the right combination of ingredients for more effective drugs – has puzzled scientists. A new University at Buffalo study, published Sept. 19 in Proceedings of the National Academy of Sciences, ...

GLP-1RA drugs dramatically reduce death and cardiovascular risk in psoriasis patients (Paris, France, Thursday, 18 September 2025) Psoriasis patients treated with glucagon-like peptide-1 receptor agonists (GLP-1RAs) face a 78% lower risk of death and a 44% lower risk of major cardiovascular events compared to those taking other diabetes or weight-loss medications, new research has shown.1 The study – the largest of its kind and presented today at the European Academy of Dermatology and Venereology (EADV) Congress 2025 – also found that GLP-1RAs ...

(Paris, France, Thursday, 18 September 2025) New research presented today at the European Academy of Dermatology and Venereology (EADV) Congress 2025 reveals that people with psoriasis face a significantly increased risk of developing age-related macular degeneration (AMD), a leading cause of vision loss.¹ Psoriasis is a chronic, systemic inflammatory disease with multiple comorbidities, including cardiovascular disease and diabetes.2 This study is among the largest to date investigating whether psoriasis ...

Details of a new drug that aims to treat the underlying causes of obesity are being presented at the annual meeting of the European Association for the Study of Diabetes (EASD) in Vienna, Austria (15-19 September). The treatment of obesity has been transformed in recent years by glucagon-like peptide-1 (GLP-1) receptor agonists such as semaglutide, which reduce appetite, slow the release of food from the stomach and increase feelings of fullness. These drugs are highly effective for weight loss but many people regain weight after stopping treatment. ...

New research being presented at this year’s Annual Meeting of The European Association for the Study of Diabetes (EASD), Vienna (15-19 Sept), reveals type 2 diabetes (T2D) as a critical factor in chronic disease accumulation, particularly during the early stages. “Concerningly, people with T2D showed faster progression to diseased states compared to those without the condition,” explained lead author Dr Jie Zhang from the Steno Diabetes Center Aarhus in Denmark. “This acceleration was observed across all age groups, with the pattern ...

Simple resistance training may help counteract age-related nerve deterioration that puts seniors at risk of injuries from falls and other accidents, according to cross-institutional research led by Syracuse University postdoctoral researcher JoCarol Shields and Department of Exercise Science Professor Jason DeFreitas. The nerves that control our muscles naturally degrade and become slower as we age, a process referred to as denervation. This degradation is especially problematic in sedentary individuals. Counteracting this deterioration with exercise could help seniors enjoy greater independence and improve ...

A Swedish-led research team at Karolinska Institutet and Karolinska University Hospital has shown in a new randomized clinical trial that a low dose of the well-known medicine aspirin halves the risk of recurrence after surgery in patients with colon and rectal cancer with a certain type of genetic alteration in the tumor. Every year, nearly two million people worldwide are diagnosed with colorectal cancer. Between 20 and 40 percent develop metastases, which makes the disease both more difficult to treat and more deadly. Previous observational studies have suggested that aspirin may reduce the risk of certain cancers and possibly also the risk of recurrence after surgery ...

SAN ANTONIO — September 17, 2025 — Two instruments developed by Southwest Research Institute (SwRI) are integrated into a National Oceanic and Atmospheric Administration (NOAA) satellite set to launch into space as a rideshare on a SpaceX Falcon 9 rocket no earlier than Sept. 23, 2025. The SwRI-built Solar Wind Plasma Sensor (SWiPS) and Space Weather Follow-On Magnetometer (SWFO-MAG) are two of four instruments integrated into NOAA’s Space Weather Follow-On Lagrange 1 (SWFO-L1) satellite. ...

  All-solid-state batteries are safe, powerful ways to power EVs and electronics and store electricity from the energy grid, but the lithium used to build them is rare, expensive and can be environmentally devastating to extract. Sodium is an inexpensive, plentiful, less-destructive alternative, but the all-solid-state batteries they create currently don’t work as well at room temperature.  “It’s not a matter of sodium versus lithium. We need both. When we think about tomorrow’s energy storage solutions, we should imagine the same gigafactory can produce products based on both lithium and sodium chemistries,” ...

Reston, VA (September 17, 2025)—A novel targeted radiation approach for a rare form of malignant tumor—the solitary fibrous tumor (SFT)—has shown significant success, achieving a near-complete response in three patients. The therapy significantly reduced cancer activity and provided symptom relief, underscoring its potential as a viable treatment option. This research was published in the September issue of The Journal of Nuclear Medicine. SFT is a rare type of soft tissue tumor with few treatment options available. Although ...
