The beta release of an innovative collaborative stand-alone authoring tool transforms manuscript preparation with semantic enrichment and real-time collaboration capabilities.
Scholarly publisher and technology provider Pensoft Publishers announces the beta launch of ORPHO, a revolutionary online platform designed to streamline collaborative scientific writing and produce AI-ready, future-proof scholarly literature.
ORPHO presents a significant advancement in scholarly publishing technology, combining intuitive writing features with sophisticated semantic enrichment capabilities. The new platform builds upon Pensoft’s fifteen years of experience as a developer of semantic publishing infrastructure.
Key Features
Within a shared online workspace, researchers can start with built-in customisable templates, create their own or import an existing file. They can then team up with collaborators in real time using track changes, role-based user rights, inline comments, and document-level chat. More significantly, ORPHO automatically structures scientific content according to international publishing standards, making research outputs findable, discoverable, interoperable and reusable (FAIR) once published.
Unlike its predecessor, the ARPHA Writing Tool, ORPHO is available as a standalone real-time collaborative workspace decoupled from journals hosted on Pensoft’s ARPHA Publishing Platform. Once a manuscript is ready, authors receive AI-FAIR machine-readable content that can be formatted to meet multiple journal requirements at the click of a button.
The platform’s adaptability to domain-specific workflows is currently being piloted in biodiversity science. ORPHO integrates seamlessly with leading biodiversity data aggregators, including the Global Biodiversity Information Facility (GBIF), Barcode of Life Data Systems (BOLD) and PlutoF, via import and export facilities for structured data, making ORPHO particularly valuable for researchers handling taxonomic, ecological and biodiversity data.
ORPHO: A new intelligent workspace for scientific writing.
Why ORPHO?
The name draws inspiration from multiple sources which reflect the tool’s philosophy and heritage. Named after Orphium: a unique plant genus endemic to South Africa whose sole species (Orphium frutescens) is known as the sea rose, ORPHO reflects the platform’s distinctive nature, heritage, and core philosophy.
It also evokes Orpheus, the legendary musician of ancient Thrace whose home region, the Rhodopi Mountains, lies in present-day Bulgaria, where ORPHO’s developer, Pensoft, is headquartered. The name thus honours the tool’s origins whilst embodying the exceptional creative performance it enables.

Prof. Dr. Lyubomir Penev, founder and CEO of Pensoft, comments:
“We are well aware that researchers today face an overwhelming list of formatting requirements and technical demands in an AI-driven landscape. It is true that rapid technological advancement presents both immense opportunities and mounting complexities for researchers.
We built ORPHO to remove that friction by offering an intuitive, collaborative workspace that lets scientists focus on their research. As a scientific publisher, our mission is to make scholarly publishing a seamless, rewarding experience fit for the modern age.”
The beta release invites researchers, institutions and publishing platforms to trial ORPHO and provide feedback. Access is available at orpho.net.
Pensoft has been awarded the Seal of Recognition for the FAO AGRIS Active Data Provider of the Year for 2027. The seal is granted by the Food and Agriculture Organisation of the United Nations through its AGRIS initiative, and it recognises institutions that consistently share open-access agricultural research with the global community.
Notably, Pensoft joined the FAO AGRIS network back in 2024, and the organisation has renewed our seal every year since, a recognition we’re proud to have kept.
What has changed is the scale of our contribution. In 2024, Pensoft’s records on AGRIS numbered just under 15,000. Today, that figure has doubled to nearly 30,000, drawn from all 51 of our journals that fall within the scope of FAO AGRIS. The subjects covered are wide-ranging, spanning taxonomy, biodiversity, conservation and biogeography – these are all areas that feed directly into sustainable agriculture and natural resource management.
Through AGRIS, this research travels well beyond our own journals to researchers, policymakers and practitioners worldwide, adding to the shared pool of open knowledge that supports global food security and environmental sustainability. We’re glad to keep contributing to that effort, and look forward to continuing our work with FAO AGRIS in the years to come.

The next time you post a nature photo online, you might be contributing to a major scientific breakthrough – just as several citizen scientists did when they helped discover the wasp Eupelmus curvator in Japan.
When a series of photos appeared on Twitter (now X) showing an iridescent wasp laying eggs on a praying mantis egg case, researchers from the Kyushu University Museum realised they weren’t looking at a common garden insect. Instead, they were witnessing a species never before seen in Japan: Eupelmus curvator.
“The discovery was made possible through social media,” said Taisuke Kawano, the lead researcher and a specialist in eupelmid wasps at the Kyushu University Museum.
“It all started with a post by a general user who shared a photo capturing a wasp emerging from a mantis egg case. A colleague of mine noticed the post and forwarded it to me via direct message.”
The wasp is the first record of Eupelmus curvator in Japan, a species previously known only to inhabit China. Perhaps more significantly, the recent study provided the first formal scientific description of the male of the species, which had remained a mystery until now.
“Eupelmus curvator is particularly interesting because it parasitises the egg cases of praying mantises.
While some other genera in Eupelmidae are specialised egg parasitoids, most species of Eupelmus attack larvae or pupae of other insects, and only very few are known to develop inside mantis oothecae. This makes Eupelmus curvator a rather unusual and biologically intriguing species.”
Taisuke Kawano
The researchers confirmed that the wasp targets the Narrow-winged Mantis (Tenodera angustipennis), turning the mantis’ future offspring into a nursery for its own young. In one case, a single mantis egg case collected in Fukuoka yielded 77 wasps and only a few surviving mantis nymphs.
In the spring of 2018 and again in 2021, citizen scientists and nature enthusiasts posted images and videos of the wasps’ behaviour on Twitter. Through direct communication on the platform, these users sent specimens to Kawano for identification.
“Social media is becoming an increasingly important tool in citizen science. One of its greatest strengths is that it effectively increases the number of ‘eyes in the field.’ These observations often come from places and times that researchers would not normally be able to cover.
When particularly interesting records appear, we can contact observers directly via social media, and in some cases obtain specimens for further study.”
Taisuke Kawano
To document the tiny find – females measure only about 2.2 to 3.2 mm excluding the ovipositor – the team used advanced macro photography and focus stacking technology to create hyper-detailed images of the wasp’s anatomy.

Science in Your Backyard
The discovery suggests that even in well-studied regions like Japan, there is a wealth of biodiversity to be uncovered. The key, according to Kawano, is that scientists are now finding it in new ways:
“One of the most exciting aspects is how social media is changing the way we conduct research. The social media platforms allow researchers to encounter observations that would otherwise remain unnoticed, effectively transforming everyday posts into valuable scientific data.”
As for his own social media habits? Kawano admits the line between work and leisure has blurred:
“Personally, I sometimes joke that even when I am browsing social media, I am actually working. And it is sometimes true… though not always.”

Pensoft Publishers is proud to celebrate International Museum Day and its 2026 theme: Museums Uniting a Divided World. This year marks the 80th anniversary of the International Council of Museums, which stresses the enduring necessity of institutions that serve as custodians of our collective memory. In alignment with this year’s focus on fostering dialogue and peace, we have curated a special “Best of the Archive” collection.
In our journal Natural History Collections and Museomics, researchers from the Institute of Ecology in Mexico demonstrate how entomological outreach can transform scientific surveys into community connections. Focusing on dung beetle research in Oaxaca, Mexico, the authors moved beyond data extraction to prioritise ethical engagement with Indigenous communities. Specifically, they utilised a knowledge exchange approach known as intercambio de saberes, which integrated “Traditional Ecological Knowledge” into the scientific process. By donating outreach collections to local libraries and documenting names in Indigenous languages like Ayuujk and Tu’un Savi, the project created a shared space for cultural and scientific dialogue.

Cultural Interaction in the Coral Sea
A review published in Tuhinga explores the “Connections across the Coral Sea” exhibition, which traces the movement of First Nations communities across Northern Queensland, the Torres Strait, and Papua New Guinea. This work, led by Safua Akeli Amaama of the Museum of New Zealand Te Papa Tongarewa, highlights a Cultural Interaction Sphere where about 100 cultural groups have traded resources and shared knowledge for centuries. The exhibition bridges geopolitical divides by showcasing shared cosmological stories, such as the star constellations known as Matariki in Aotearoa New Zealand and Usiam in the Torres Strait. This inclusive approach to curation honours the maritime technologies and spiritual connections that have long linked these diverse coastal regions.

Citizen Science and Social Inclusion in Cyprus
The journal Travaux du Muséum National d’Histoire Naturelle “Grigore Antipa” highlights the power of public participation in its report on the first records of the Giant water bug in Cyprus. This research relied almost entirely on data provided by biodiversity enthusiasts through social media networks. Validating findings from non-scientists allows for the museum to foster a sense of inclusion and empowers local citizens to contribute to national biodiversity monitoring. This collaboration represents an important bridge between professional researchers and the broader community, ensuring that scientific knowledge is a collective achievement rather than an isolated one.

Digital Repatriation from Aotearoa to West Africa
In Papahou: Records of the Auckland Museum, an article examines how open cultural heritage practices connect Aotearoa New Zealand with West Africa. Through partnerships with Wikimedia, the Auckland Museum is facilitating digital access to Nigerian and Ghanaian artifacts for their source communities. This initiative addresses questions of authority and authorship by allowing local advocates in Ghana and Nigeria to shape how their heritage is represented online. Indeed, by adopting a policy of “open by default, closed by exception”, the museum balances the democratisation of knowledge with the need for cultural safety and Indigenous sovereignty.

Confronting Colonial History in Vienna
The Annals of the Natural History Museum Vienna contributes to cultural diplomacy by critically examining the provenance of osteological collections acquired during 19th-century naval expeditions. This interdisciplinary study investigates the ethical challenges of human remains collected from East Africa and Madagascar. It is becoming increasingly clear that the documentation of the circumstances of acquisition and the presence of colonial violence in the historical record is necessary to the adoption of better guidelines for future engagement and repatriation. This transparent approach to difficult histories is essential for building trust and understanding between European institutions and the communities whose heritage they hold.

The island of Cyprus, although considered a hotspot for biodiversity in the Mediterranean, is more famous for its beautiful sunny coasts than for its insect fauna. Nevertheless, some visitors of its highly populated beaches, with their observations and curiosity, have provided important information for a species never recorded before on the island: a giant water bug, also known as a toe biter.
Giant water bugs.
Scientists Michael Hadjiconstantis from the Association for the Protection of Natural Heritage and Biodiversity of Cyprus, Iakovos Tziortzis from the Ministry of Agriculture, Rural Development and Environment of Cyprus, and Kadir Boğaç Kunt from the Cyprus Wildlife Research Institute collected information and specimens from an increasing number of records of the giant water bug on the east coastline of the island in late spring and summer of 2020 and 2021. The species, known for inhabiting ponds and slowly moving freshwaters, had never been recorded on the island before, although established populations are known in adjacent Mediterranean countries such as Greece, Turkey, and Israel.
Locations of the reported Giant water bug sightings in Cyprus.
Also referred to as Electric light bug, this giant water bug is described as a vicious hunter, praying on invertebrates, fish, turtles, and even birds. What is even scarier, as the largest European true bug and the largest European water insect and measuring up to 12 cm, it has a reputation of inflicting very painful bites when handled carelessly.
A giant water bug found in Paralimni.
Its appearance, mainly on the eastern coastal front of the island, was initially recorded by swimmers, who were surprised by the fearsome looks and size of the bug. They either directly contacted the experts or published photos and videos online, mainly on Facebook groups related to biodiversity. The authors collected some of the specimens for further study. They also proceeded with an extensive online search on relevant online observation platforms (i.e. iNaturalist) in order to track any other reports of the species on the island. In addition, they sampled nearby wetlands, but did not spot the bug. End to end, a total of seven sightings were eventually recorded: five from social media and two after direct communication with the author team. Two specimens were obtained and examined morphologically to verify the species. The observations were recorded in a research article in the open-access journal Travaux du Muséum National d’Histoire Naturelle “Grigore Antipa”.

Having in mind that the toe biter is an iconic species accompanied by creepy stories concerning its encounters with humans, the authors assume that it is unlikely that it had gone unnoticed for too long. They consider it possible that several migration events might have been triggered in a short period of time by nearby countries hosting the species, such as Israel, Lebanon, and Syria. The specimens could have been transferred by wind or sea currents, as assumed by other researchers, or could have been driven by a decrease in food resources in their initial area of distribution.
Despite the number of recordings in a short timeframe, no conclusions can be drawn for the moment on the establishment of a population of the species on the island. This is further to be investigated, and as the initial recording of the species, citizen science can have an important role in this. The authors urge the public to be alert: “Naturalists looking for alien-like critters can provide valuable information on the presence and a possible establishment of the species through citizen science.” Until then, they warn: “Cypriots should keep their eyes open and their toes out of the water”.

All journals published by Pensoft – each using the publisher’s self-developed ARPHA Platform – provide extensive and transparent information about their costs and services in line with the Plan S principles.
In support of transparency and openness in scholarly publishing and academia, the scientific publisher and technology provider Pensoft joined the Journal Comparison Service (JCS) initiative by cOAlition S, an alliance of national funders and charitable bodies working to increase the volume of free-to-read research.
As a result, all journals published by Pensoft – each using the publisher’s self-developed ARPHA Platform – provide extensive and transparent information about their costs and services in line with the Plan S principles.
The JCS was launched to aid libraries and library consortia – the ones negotiating and participating in Open Access agreements with publishers – by providing them with everything they need to know in order to determine whether the prices charged by a certain journal are fair and corresponding to the quality of the service.
According to cOAlition S, an increasing number of libraries and library consortia from Europe, Africa, North America, and Australia have registered with the JCS over the past year since the launch of the portal in September 2021.
While access to the JCS is only open to librarians, individual researchers may also make use of the data provided by the participating publishers and their journals.
This is possible through an integration with the Journal Checker Tool, where researchers can simply enter the name of the journal of interest, their funder and affiliation (if applicable) to check whether the scholarly outlet complies with the Open Access policy of the author’s funder. A full list of all academic titles that provide data to the JCS is also publicly available. By being on the list means a journal and its publisher do not only support cOAlition S, but they also demonstrate that they stand for openness and transparency in scholarly publishing.
“We are delighted that Pensoft, along with a number of other publishers, have shared their price and service data through the Journal Comparison Service. Not only are such publishers demonstrating their commitment to open business models and cultures but are also helping to build understanding and trust within the research community.”
said Robert Kiley, Head of Strategy at cOAlition S.

By the time authors – who have acknowledged third-party financial support in their research papers submitted to a journal using the Pensoft-developed publishing platform: ARPHA – open their inboxes to the congratulatory message that their work has just been published and made available to the wide world, a similar notification will have also reached their research funder.
This automated workflow is already in effect at all journals (co-)published by Pensoft and those published under their own imprint on the ARPHA Platform, as a result of the new partnership with the OA Switchboard: a community-driven initiative with the mission to serve as a central information exchange hub between stakeholders about open access publications, while making things simpler for everyone involved.
All the submitting author needs to do to ensure that their research funder receives a notification about the publication is to select the supporting agency or the scientific project (e.g. a project supported by Horizon Europe) in the manuscript submission form, using a handy drop-down menu. In either case, the message will be sent to the funding body as soon as the paper is published in the respective journal.
“At Pensoft, we are delighted to announce our integration with the OA Switchboard, as this workflow is yet another excellent practice in scholarly publishing that supports transparency in research. Needless to say, funding and financing are cornerstones in scientific work and scholarship, so it is equally important to ensure funding bodies are provided with full, prompt and convenient reports about their own input.”
comments Prof Lyubomir Penev, CEO and founder of Pensoft and ARPHA.
“Research funders are one of the three key stakeholder groups in OA Switchboard and are represented in our founding partners. They seek support in demonstrating the extent and impact of their research funding and delivering on their commitment to OA. It is great to see Pensoft has started their integration with OA Switchboard with a focus on this specific group, fulfilling an important need,”
adds Yvonne Campfens, Executive Director of the OA Switchboard.

The Red List of Taxonomists portal, where taxonomy experts in the field of entomology can register to help map and assess expertise across Europe, in order to provide action points necessary to overcome the risks, preserve and support this important scientific community, will remain open until 31st October 2021.
Insect taxonomists, both professional and citizen scientists, are welcome to register on the Red List of Taxonomists portal at: red-list-taxonomists.eu and further disseminate the registration portal to fellow taxonomists until 31st October 2021.
Within the one-year project, the partners are to build a database of European taxonomy experts in the field of entomology and analyse the collected data to shed light on the trends in available expertise, including best or least studied insect taxa and geographic distribution of the scientists who are working on those groups. Then, they will present them to policy makers at the European Commission.
By recruiting as many as possible insect taxonomists from across Europe, the Red List of Taxonomists initiative will not only be able to identify taxa and countries, where the “extinction” of insect taxonomists has reached a critical point, but also create a robust knowledge base on taxonomic expertise across the European region to prompt further support and funding for taxonomy in the Old Continent.
On behalf of the project partners, we would like to express our immense gratitude to everyone who has self-declared as an insect taxonomist on the Red List of Taxonomists registration portal. Please feel welcome to share our call for participation with colleagues and social networks to achieve maximum engagement from everyone concerned about the future of taxonomy!

Bird diets provide a real treasure for research into the distribution and conservation of their prey, conclude scientists after studying the Eurasian Eagle Owl in southeastern Bulgaria. In their paper, published in the open-access, peer-reviewed journal Travaux du Muséum National d’Histoire Naturelle “Grigore Antipa”, they report the frequent presence of the threatened Big-Bellied Glandular Bush-Cricket, and conclude that studies on the Eurasian Eagle Owl could be used to identify biodiversity-rich areas in need of protection.

Bird diets provide a real treasure for research into the distribution and conservation of their prey, such as overlooked and rare bush-cricket species, point out scientists after studying the diet of the Eurasian Eagle Owl (Bubo bubo) in southeastern Bulgaria.
While the Balkan Peninsula has already been recognised as the area with the highest diversity of orthopterans (grasshoppers, crickets and bush-crickets) in Europe and one of the generally most biologically diverse areas in the whole Palearctic realm, it is also home to a worrying number of threatened species. Additionally, a thorough and updated country assessment of the conservation status of the orthopterans found in Bulgaria is currently lacking. This is why the Bulgarian team undertook a study on the biodiversity of these insects by analysing food remains from pellets of Eurasian Eagle Owls, collected from 53 breeding sites in southeastern Bulgaria.
As a result, the scientists reported three species of bush crickets that have become a significant part of the diet of the studied predatory birds. Curiously enough, all three species are rare or threatened in Bulgaria. The case of the Big-Bellied Glandular Bush-Cricket is of special concern, as it is a species threatened by extinction. Meanwhile, the local decline in mammals and birds that weigh between 0.2 and 1.9 kg, which are in fact the preferred prey for the Eurasian Eagle Owl, has led the highly opportunistic predator to increasingly seek large insects for food. The researchers even suspect that there might be more overlooked species attracting the owls.
Taking into account the hereby reported interconnected inferences of conservation concern, as well as the vulnerability of the Big-Bellied Glandular Bush-Cricket, a species with a crucial role in the food chain, the scientists call for the newly provided data to prompt the designation of a new Natura 2000 site. Additionally, due to the species’ requirements for habitats of low disturbance and high vegetation diversity, and its large size and easy location via singing males, they point out that it makes a suitable indicator for habitat quality and species community health.
