The team used the system to study deep-sea octopus and shared their findings in the scientific journal Nature. EyeRIS (Remote Imaging System) can capture detailed three-dimensional visual data about the structures and movement of marine life in their natural deep-sea habitat. MBARI researchers integrated EyeRIS on board a remotely operated vehicle to observe deep-sea pearl ...

Mutations in a single gene, HNF1A, are known to cause MODY3, a rare, early onset form of diabetes. Smaller scale mutations in the very same gene are also common and quietly nudge millions of people toward type-2 diabetes. A study published today in Cell Metabolism reveals why. Researchers at the Centre for Genomic Regulation (CRG) in Barcelona show it’s fundamentally a problem of insulin-producing β‑cells. Using mouse models, they switched HNF1A off in different tissues and cell types including the liver, the gut and both α and β‑cells in the pancreas, ...

An international team led by scientists from the Canadian Museum of Nature and the University of Chicago reconstructed the brain, heart, and fins of an extinct fish called Norselaspis glacialis from a tiny fossil the size of fingernail and found evidence of change toward a fast-swimming, sensorily attuned lifestyle well before jaws and teeth were invented to better capture food. “These are the opening acts for a key episode in our own deep evolutionary history,” said Tetsuto Miyashita, who is a research scientist with the ...

Tay-Sachs and Sandhoff diseases, genetic disorders affecting the brain, have no effective treatment and are typically fatal within the first years of life. Scientists have reasoned that replacing the affected cells with those that are genetically healthy could slow or halt the neural degeneration that causes the symptoms. But the approach has been plagued with problems, including poor engraftment in the brain and a graft-versus-host response in which transplanted cells attack healthy tissue. Now researchers at Stanford Medicine have developed a way to replace more than half of the most severely affected cells, called microglia, with ...

Arthropods, including insects and spiders, make up the vast majority of animal species on the planet. Despite their small size they are irreplaceable contributors to the health of natural habitats, as well as vital food sources for birds and other larger animals. But, arthropods may be declining globally. There is some evidence to support reduced numbers of species in temperate regions of the Northen Hemisphere. In the tropics, however, evidence for arthropod declines has so far been limited. A recent international collaboration of scientists has attempted to find this missing evidence, with the findings published in Nature. The ...

In nanophotonics, tiny structures are used to control light at the nanoscale and render it useful for technological applications. A key element here is optical resonators, which trap and amplify light of a certain color (wavelength). Previous methods of controlling these resonances were more like a dimmer switch: You could weaken the resonance or slightly shift its color. However, genuine on-and-off switching was not possible, as the resonators always remain fundamentally coupled with the light. A team led by Andreas Tittl, Professor of Experimental Physics at LMU, has now achieved precisely this breakthrough together with partners from Monash ...

Recent findings, made by Griffith University researchers, show that early hominins made a major deep-sea crossing to reach the Indonesian island of Sulawesi much earlier than previously established, based on the discovery of stone tools dating to at least 1.04 million years ago at the Early Pleistocene (or ‘Ice Age’) site of Calio. Budianto Hakim from the National Research and Innovation Agency of Indonesia (BRIN) and Professor Adam Brumm from the Australian Research Centre for Human Evolution at Griffith University led the ...

With the global rollout of 5G networks and the onset of 6G research, the need for advanced materials that enable faster and more reliable wireless communication has never been greater. Microwave dielectric ceramics, key components in devices like resonators, filters, and antennas, must meet strict criteria: low signal delay, low loss, and stable performance across temperatures.   A research team from Guilin University of Technology in China has risen to this challenge by developing a novel garnet-type ceramic, YMAG. Synthesized using a solid-state reaction method, YMAG exhibits impressive microwave properties: a permittivity (εr) of 9.86, a quality factor ...

Australian researchers have visualised a key protein complex in malaria parasites for the first time, uncovering a new target for next-generation vaccines that could help stop the disease from spreading. Using cutting-edge cryo-electron microscopy, the research team from WEHI captured the first detailed structure of a protein complex essential for malaria parasite fertilisation. The discovery published in Science has led to the development of a promising new mRNA vaccine candidate that stops the malaria parasite from reproducing inside mosquitoes, breaking the cycle of transmission ...

WASHINGTON (August 6, 2025) — Using portable high-efficiency particulate air (HEPA) purifiers at home can significantly lower systolic blood pressure (SBP) in adults with elevated baseline readings — even in areas with relatively low overall air pollution levels, according to a study published today in JACC, the flagship journal of the American College of Cardiology.   Particulate matter (PM) is a major contributor to air pollution and is strongly associated with cardiovascular disease (CVD). People ...

(WASHINGTON – August 6, 2025) – Most patients with high-risk myelodysplastic syndromes (MDS) do not receive guideline-recommended treatment with hypomethylating agents (HMAs), according to results published in Blood Neoplasia. The findings suggest that underuse of these drugs may help explain why MDS outcomes have not improved over the past two decades since these life-extending medications became available.   The study is the largest analysis of MDS treatment patterns in the United States to date and the most comprehensive study of real-world use of HMAs, which are highly effective in improving outcomes. HMAs are the best available ...

COLUMBUS, Ohio – The established conservation practice of relocating animals from large, genetically diverse populations to small communities of inbred endangered species may risk introducing more damaging than beneficial gene variants into the threatened group, a new study suggests. Analysis of genomes of Eastern massasauga rattlesnakes showed that, by the numbers, more deleterious than adaptation-enabling mutations were present in the more genetically diverse donor animals selected in a hypothetical scenario to join a small, isolated population. Because donor relocation, known as ...

The research group of fungal diversity and molecular evolution at Kunming Institute of Botany, Chinese Academy of Sciences conducted in-depth research on more than 1,600 samples of macrofungi collected from 2019 to 2024 by means of species identification combining morphology and molecular systematics. The results showed that there were 480 species of macrofungi in this area, covering 7 classes, 17 orders, 67 families, and 158 genera of Ascomycota and Basidiomycota, and 8 new species were described.   Fungal diversity patterns revealed taxonomic dominance at both family and genus levels. Among the 67 documented families, 15 were dominant (≥10 species each), collectively representing ...

Given the current youth mental health crisis in the United States, many adolescents report experiencing low levels of hope – a longstanding concern that is even more pressing as the new school year begins. Substantial research over decades has established that higher levels of hope are linked with greater academic achievement, as well as improved emotional and physical health. Now, a new study shows that hope does even more: it acts as a powerful protective force in the lives of children, helping to reduce both bullying and cyberbullying. The study by Florida Atlantic University, in collaboration with the University of Wisconsin–Eau Claire, surveyed a nationally representative ...

New York, NY [August 6, 2025] — A new study by researchers at the Icahn School of Medicine at Mount Sinai finds that widely used AI chatbots are highly vulnerable to repeating and elaborating on false medical information, revealing a critical need for stronger safeguards before these tools can be trusted in health care. The researchers also demonstrated that a simple built-in warning prompt can meaningfully reduce that risk, offering a practical path forward as the technology rapidly evolves. Their findings were detailed in the August 2 online issue of Communications Medicine ...

As a chronic condition, rheumatoid arthritis (RA) can’t be cured, so treatment focuses on managing the disease and controlling its progression. Although current treatments help control RA symptoms in most people, they cannot prevent the onset of RA or painful flare-ups. Now, researchers publishing in ACS Central Science have developed nanoparticles that could slow disease progression and reduce flare severity, based on results from tests with human blood and mice models with RA-like disease. For a person diagnosed with RA, their immune system attacks tissue that makes up the joints, causing inflammation, swelling and pain. ...

Multinational enterprises (MNEs) can negate supplier-induced environmental, social and governance (ESG) controversies by setting up ‘small-world’ networks, according to new research co-authored by Bayes Business School. Globalising supply chains has become a dominant strategy for MNEs. Benefits include lower costs of labour and distribution, and greater scope for innovation. However, long-distance operations also carry associated risks. Contrasting ethical standards of suppliers in different areas of the world can lead to ...

Quantum distance refers to a measure of quantum mechanical similarity between two quantum states. A quantum distance of one means that the two quantum states are the same, whereas a quantum distance of zero implies that they are exactly the opposite. Physicists introduced this concept in the realm of theoretical science a long time ago, but its importance has been increasingly recognized in the field of physics only in recent times. In the last few years, many experimental physicists have tried to measure the quantum distance of electrons ...

The mitral valve controls blood flow between the heart’s left atrium and ventricle. When structural changes affect the atrium or valve, it may not close fully—causing blood to leak backwards, a condition known as atrial functional mitral regurgitation (AFMR). Common in frail or elderly patients, AFMR often leads to heart failure, and standard surgery is typically too risky due to other health issues.   Transcatheter edge-to-edge repair (TEER), a minimally invasive surgery, has emerged as a low-risk treatment option for various ...

Research Highlights: Increased time on electronic devices or watching TV among children and young adults was associated with higher cardiometabolic disease risk, such as high blood pressure, high cholesterol and insulin resistance, based on data from over 1,000 study participants in Denmark. The link between screen time and cardiometabolic risks was strongest among youth who slept fewer hours, suggesting that screen use may harm health by “stealing” time from sleep, researchers said. Researchers said the findings underscore the ...
