Ultrafast scanning tunneling microscopy reaches the quantum mechanical space-time limit for the first time
Researchers have achieved a breakthrough in observing the 'space-time limit' for electrons, where the simultaneous measurement of their location and time evolution becomes fundamentally limited by quantum mechanics. This discovery, made by teams from the Regensburg Center for Ultrafast Nanoscopy (RUN) and the Max Planck Institute in Hamburg, could impact future technologies like quantum computing and high-performance electronics. They used ultrafast scanning tunneling microscopy combined with advanced laser systems to track electron movement on attosecond time scales, revealing behaviors governed by quantum principles rather than classical mechanics.
Study reveals systemic barriers slowing down circular plastics transition
A study from the University of Eastern Finland identifies systemic barriers hindering the transition to a circular plastics economy. Researchers highlight that factors like regulation, technology, market structures, consumer behavior, and collaboration create interconnected but conflicting dynamics that limit progress. The study introduces the 'recycling for nothing paradox,' noting that despite substantial investment in recycling and sustainability efforts, misalignments across the ecosystem reduce their effectiveness. The findings emphasize the need to address contradictions within the system rather than focusing on isolated solutions. The research, published in the Journal of Circular Economy, aims to inform companies, policymakers, and researchers working on sustainable plastics systems.

There may be 3 times more insect species than previously thought
A recent scientific study suggests that the global number of insect species could be significantly higher than previously believed, estimating between 8 million to 14 million additional species that remain undiscovered. Current estimates suggest around 6 million known insect species, but this research uses genetic data from over 1.6 million tropical insects, particularly focusing on parasitoid wasps in Costa Rica, along with statistical models, to propose a much larger figure of up to 20 million insect species. This finding highlights the vast underestimation of insect diversity and emphasizes the importance of understanding biodiversity to effectively conserve it. Researchers note that insects' high diversity stems from factors like metamorphosis and their ability to thrive in varied environments. The study was conducted using extensive sampling in Costa Rica’s ACG protected area, employing techniques such as Malaise traps and DNA barcoding to catalog species.
U tropskom Pacifiku nastaju El Niño uvjeti, kažu istraživači
ESNZ se pridružio drugim organizacijama u Australiji, Japanu i SAD-u u potvrđivanju razvoja El Niña, za koji se očekuje da će dostići snažan intenzitet između srpnja i rujna. Očekuje se da će učinci dostići vrhunac tijekom ljeta na južnoj hemisferi, koji se proteže krajem 2023. do početka 2024. Prema vodećem istraživaču Chrisu Brandoliniju, ovaj El Niño događaj je barem usporediv po snazi s pet najjačih El Niño zabilježenih u modernoj povijesti.
Researchers recreate a lost Ming Dynasty goldworking technique to make replica royal jewelry
Researchers from the China University of Geosciences successfully recreated a lost Ming Dynasty goldworking technique called Jin zhe si, which allows for the creation of intricate filigree-like patterns without using wire. By studying gold earrings found in the tomb of Prince Zhu Zairong, they discovered that the technique involved folding thin gold foil into layered, corrugated structures. Using historical records and microscopic analysis, the team reverse-engineered the process and created a replica that closely matched the original in form, texture, and weight. They tested the method with silver and aluminum, but only high-purity gold could be folded repeatedly without breaking, highlighting the unique properties required for this ancient technique.
Tax-avoiding firms more likely to greenwash, analysis of 391 ASX companies suggests
A study conducted by Murdoch University and published in Business Strategy & Development analyzed 391 Australian Securities Exchange-listed companies between 2019 and 2022. The research found a correlation between aggressive tax avoidance and 'greenwashing'—where companies exaggerate their environmental responsibilities. Lead researcher Dr. Augustine Donkor noted that during economic uncertainty, such as the COVID-19 pandemic, companies may prioritize image management over genuine sustainability efforts. The study also revealed that companies employing a 'defender' business strategy, typically focused on stability and cost control, were more likely to engage in greenwashing when they perceive it as a low-cost reputational tool. The findings emphasize the need for improved transparency and stricter oversight of both sustainability reports and corporate tax practices.
Hot Jupiter winds reveal exoplanet magnetic fields for first time
Astronomers have discovered magnetic fields on 'hot Jupiters,' a type of exoplanet with extremely high surface temperatures, marking the first direct evidence of such fields beyond our solar system. Using telescopes like the European Southern Observatory's Very Large Telescope in Chile, researchers observed extreme wind patterns on these gas giants, which range from 7,200 to 25,000 km/h. Surprisingly, hotter planets exhibited weaker winds, suggesting the presence of magnetic fields that slow charged particles. The findings, published in Nature Astronomy, indicate that these exoplanets possess magnetic fields comparable in strength to those of Jupiter and Earth, offering new insights into planetary atmospheres and potential habitability.
Izuzetno slaba galaksija otkrivena u blizini Andromede možda je stara 12,5 milijardi godina
Astronomi su otkrili novu ultra-slabku patuljastu galaksiju And XXXVI u blizini Andromedine galaksije (M31), koja je najbliži glavni galaktički susjed Mliječnog puta. Studija, objavljena u časopisu Astronomy & Astrophysics, sugerira da je And XXXVI jedan od najslabijih poznatih satelita Andromede i da bi mogao biti star gotovo 12,5 milijardi godina. Smatra se da su ultra-slabke patuljaste galaksije ostaci ranog svemira i da u njima prevladava tamna materija, što ih čini ključnim za razumijevanje formiranja galaksija i testiranje teorija tamne materije. Istraživači napominju da, iako je poznato da oko 40 patuljastih galaksija kruži oko Andromede, samo ih je oko 15 klasificirano kao ultra-slabke, što znači da ih je možda još mnogo koje treba otkriti. Potrebna su daljnja promatranja pomoću svemirskih teleskopa poput Hubblea kako bi se potvrdili detalji kao što su precizna udaljenost, starost i kemijski sastav galaksije.
Narrow time windows shaped passage for salmon, trout and lamprey at Haringvliet sluices, 18-year analysis shows
A study published in Movement Ecology analyzed the migration patterns of Atlantic salmon, sea trout, and sea lamprey through the Haringvliet Sluices using data from 1,751 tagged fish collected between 1996 and 2018. The research revealed that less than one-third of migratory fish successfully entered the Rhine-Meuse delta, with most passing through the sluices during specific time windows, particularly toward the end of discharge periods when water levels and flow velocities were more favorable. The study also noted differences in passage behavior among species, with Atlantic salmon showing high selectivity for specific conditions and timing, while sea trout exhibited greater variability. Some fish bypassed the Haringvliet Sluices entirely by using the Port of Rotterdam as an alternative route.
JWST discovers a new barred spiral galaxy
Astronomers have discovered a new barred spiral galaxy named M1149-BSG-z5 using the James Webb Space Telescope (JWST). The galaxy, located at a redshift of 5.1, is notable for hosting a stellar bar measuring approximately 14,700 light-years in length, making it the highest-redshift barred galaxy identified to date. It has an effective radius of about 8,500 light-years, with spiral arms extending up to 17,900 light-years. The galaxy's mass is estimated at 28 billion solar masses, and it exhibits a star-formation rate of 144 solar masses per year. Additionally, M1149-BSG-z5 hosts an active galactic nucleus (AGN) with a relatively low black-hole-to-stellar mass ratio, suggesting it may represent a transitional phase in galaxy evolution. The findings were published on the preprint server arXiv.
Third UK heatwave increasingly likely as 30C temperatures forecast
An upcoming heatwave in the UK is being predicted, with temperatures potentially reaching 30°C in parts of the southeast by the weekend. The Met Office reports that June 2026 was the warmest June on record for England and the second warmest for the UK overall. A high-pressure system from the Azores is moving toward the Iberian Peninsula, contributing to rising temperatures. While the UK typically declares a heatwave when temperatures meet specific regional thresholds—such as three consecutive days of 28°C in London and the southeast—the current conditions suggest the heatwave might begin earlier than usual. The UK Health Security Agency has issued heat health alerts for several regions, cautioning about risks to vulnerable individuals. Although the air is expected to be less humid compared to previous heatwaves, the potential for discomfort remains. Northern areas are unlikely to experience heatwave-level temperatures soon due to the influence of Atlantic air and possible rainfall.
Study demonstrates neurotransmitter communication in immune cells directly for the first time
Researchers from the University of Münster and Ruhr University Bochum have discovered that neutrophils, a type of white blood cell, use catecholamines—such as dopamine and adrenaline—to communicate in real time, similar to how nerve cells function. Using fluorescent carbon nanotube sensors, they observed that neutrophils absorb, store, and release these neurotransmitters in response to inflammation. This finding reveals a previously unknown connection between the immune system and the nervous system, showing that catecholamines regulate both immune responses and blood clotting. The study suggests that this mechanism is active in humans, based on experiments involving healthy volunteers. The research was published in the journal Advanced Science.
