The World Veterinary Poultry Association (WVPA) was formed in 1959, the honour of being the first President of the Association going to Professor de Blieck and that of Secretary to Dr R.F. Gordon, who had both championed its formation. The First WVPA Conference (the name "Congress" was not applied until the third meeting) took place in Utrecht in 1960. The second Conference (1962) and the third Congress (1965) were in Cambridge and Paris, respectively. The fourth Congress, in Belgrade (1969), was a landmark one for two reasons: firstly, submitted papers were introduced, and secondly, the notion of a WVPA journal, later to be called Avian Pathology, was first discussed. A year later (1970) the journal came into being, Professor Klimes (Czhechoslovakia), the driving force behind its creation, being the first Editor-in-Chief, with Professor Kosic (Yugoslavia) as production Editor. Due to the ill health of Professor Klimes, Peter Biggs was confirmed as Editor-in-Chief in 1973. A charitable company, Avian Pathology Ltd, was formed in 1980, under which Avian Pathology was published. Dr L.N. (Jim) Payne succeeded Dr Biggs as Editor-in-Chief in 1988. The fifth and six Congresses were in Munich (1973) and Atlanta, Georgia, USA (1977), respectively. Four years later, at the Oslo Congress, it was agreed that the rather crude logo adopted at the fourth Congress should improved. This was done and is the current logo. On the 25th anniversary (1985) of the first WVPA Congress, the eighth Congress was held in Jerusalem. Membership had increased to almost 1000, with members in 39 countries, 22 of which had branches of WVPA. In 4 years it will be time to publish an account of the second 25 years in the history of the WVPA.

Scientists at the University of Hong Kong have created a remarkable new type of brain-inspired chip that can function just above absolute zero, one of the coldest environments imaginable。 By using a standard silicon carbide transistor in a completely new way, the team made a single device behave like an energy-efficient neuron, firing electrical “s
A stunning spiral galaxy called Messier 88 is racing through the crowded Virgo Cluster on a journey that will dramatically reshape its future。 At its heart lies a supermassive black hole about 100 million times the mass of the Sun, while its graceful spiral arms sparkle with young star clusters and dark clouds of dust。 But as M88 plunges deeper int
Vulnerability in the Oracle-owned PeopleSoft software is about as critical as they come
JWST has revealed dramatic differences between the dawn and dusk regions of the scorching exoplanet WASP-121 b。 Fierce winds appear to carry heat from the planet’s permanent dayside, making the evening side hotter and more expanded。 Scientists also found signs that water is being broken apart by extreme temperatures and that mysterious mineral clou
Scientists have uncovered unexpected quantum complexity inside cobalt, a metal long thought to be fully understood。 Advanced measurements revealed a dense network of topological electronic states that remain robust at room temperature。 These states enable extremely fast electron behavior and can be switched or controlled using magnetism
Researchers gave top AI models a classic attention test used in psychology and found a major flaw。 While the models could correctly name colors in short lists, their performance deteriorated sharply as the task became longer and more complex。 Some leading systems fell from over 90% accuracy to nearly complete failure
NASA’s futuristic X-59 jet is about to face its biggest challenge yet: breaking the sound barrier for the first time。 After a successful series of test flights that pushed the aircraft to near-supersonic speeds, engineers are preparing to fly it faster than Mach 1 and eventually up to Mach 1。6 at 60,000 feet
Researchers discovered a way to reverse the direction of energy flow in turbulence, challenging a theory that has stood for more than 80 years。 The finding could open new possibilities for controlling ocean currents, improving medical technologies, and enhancing climate forecasting
Scientists at Lawrence Livermore National Laboratory recreated part of the intense chaos inside a nuclear fireball to better understand how radioactive fallout forms。 Their experiments revealed that the way vaporized materials cool can dramatically change the particles that eventually form, especially for volatile elements like cesium
A lightweight new X-ray telescope could finally give scientists something they’ve never had before: a complete chemical map of the Moon。 Researchers used detailed mission simulations to show that a compact telescope orbiting the Moon could identify key elements across the entire lunar surface, helping reveal how the Moon formed and evolved
NASA's James Webb Space Telescope has uncovered unusual chemistry in interstellar comet 3I/ATLAS, including the first direct detection of methane on a visitor from another star system。 The comet also contains exceptionally high levels of carbon dioxide, making it unlike most comets born in our solar system。 Scientists believe the methane was hidden
New studies suggest consciousness can't be judged solely by behavior, whether it's a chatbot discussing philosophy or a bee searching for nectar。 Researchers are increasingly focusing on the internal mechanisms of brains and computers, concluding that today's AI is likely not conscious while leaving open the possibility for both conscious insects a
Scientists discovered that rice behaves in a highly unusual way: it weakens under rapid compression but stays stronger when pressure is applied slowly。 Using this effect, they engineered a new material that reacts differently to gentle movements and sudden impacts。 The material can adapt its stiffness automatically, opening the door to safer soft r
NASA’s PExT terminal has shown that spacecraft can seamlessly communicate through multiple government and commercial networks, a major step beyond traditional single-network systems。 The mission is now expanding to test new capabilities that could help create a more flexible, reliable communications infrastructure for future space missions
Scientists found that transfer learning can make the search for new physics in the universe much faster, slashing the need for expensive simulations。 Yet the approach can backfire when AI relies too heavily on familiar patterns, potentially missing evidence of something truly new
Researchers have finally resolved a key problem in a 100-year-old theory of color, showing that the qualities we perceive in colors are intrinsic to the mathematics of color space itself。 The discovery sharpens our understanding of human vision and could lead to more precise color technologies and visualizations
