Scientists studied the effects of two hot stars, Epsilon and Beta Canis Majoris, on the local interstellar clouds around our solar system. The team found that these stars' ultraviolet radiation ionized about 20% of the hydrogen atoms and 40% of the helium atoms in the clouds.
A new open-source tool, SCGraph, enables users to calculate the shortest connection between two points worldwide across different transport modes. The system is based on a novel shortest path model that integrates data from road, rail, and maritime routes.
A new combination therapy approach enabled seven out of ten participants to keep the virus at low levels for many months after going off antiretroviral therapy. The results suggest a possible cure for HIV and offer a proof of concept that this approach could work.
A randomized controlled trial found that home hospital care reduced healthcare costs by 27% and increased physical activity among patients with acute conditions. Patients also reported higher satisfaction rates when receiving care at home compared to traditional brick-and-mortar hospitals.
A molecule capable of opening the 'shell' of HIV allows specific antibodies to trigger a cytotoxic reaction, facilitating the elimination of infected cells. The compound, CJF-III-288, modifies the HIV envelope protein structure, making it detectable and vulnerable to the immune system.
A new study published in Nature Geoscience shows the key role of Antarctic Bottom Water in the transition from the last Ice Age. The expansion of AABW played a central role in releasing carbon dioxide into the atmosphere, which helped reduce atmospheric CO2 concentrations.
Researchers analyzed 1,240 wastewater samples from 351 cities worldwide and discovered latent antimicrobial resistance genes. The study highlights the need for broader surveillance of resistance in wastewater to curb future pandemics.
Humpback whales are experiencing a significant recovery, with an estimated population of 80,000, thanks to their ability to adapt to changing food sources. Researchers observed humpback whales switching from polar cod to krill in response to changes in the Senyavin Strait ecosystem.
Researchers developed a machine learning tool, SAMP-Score, to identify compounds that induce senescence in p16-positive cancer cells. The tool successfully identified a promising candidate, QM5928, which triggers senescence without killing cancer cells.
Researchers at RMIT University have created nanodots made from molybdenum oxide that can selectively kill cancer cells while leaving healthy cells unharmed. The particles release reactive oxygen molecules that trigger cell death, offering a new strategy for designing targeted cancer treatments.
A team from Maynooth University is using the Mauve telescope to investigate how stars and planets form, focusing on Herbig Ae/Be stars. The research aims to identify variability and search for signs of early planet formation.
A team of researchers from EPFL, Empa, and CSEM has created a sustainable smart sensing tag that can detect temperature thresholds in shipments of medicines and food products. The biodegradable sensor tag is made from environmentally friendly materials and eliminates the need for silicon-based sensors and wireless chips.
Scientists at Cold Spring Harbor Laboratory are studying Alston's singing mice to better comprehend the evolutionary origins of vocal communication. The research may also hold clues for understanding strokes, autism, and other speech-related disorders. The study found that singing mice use a common brain region for both singing and ult...
The Southwest Research Institute (SwRI) has launched a new laboratory to investigate the chemical origins of planetary systems. The Nebular Origins of the Universe Research Laboratory aims to connect pre-planetary evolution to planetary formation, filling key data gaps in understanding the solar system's early history.
Scientists at The University of Osaka reproduced multiple statistical characteristics of slow earthquakes using gel jelly beads on a liquid surface. The study suggests that slow earthquakes exhibit anomalously long and small slips adjacent to regular earthquakes, with potential implications for probabilistic earthquake assessments.
A study published in Nature Communications reveals that adult marine bristleworms have a ring of neural stem cells that actively divide when growing their eyes, driven by environmental light. The research also shows that these stem cells are regulated by a c-opsin molecule, similar to those found in vertebrate retinas.
Researchers found that urban female Eurasian red squirrels have a higher pregnancy rate and reproduce earlier than rural females. Urban females also reproduced longer, with some continuing up to five years of age, compared to four years in rural populations.
A new study using advanced imaging found that abdominal obesity is associated with more harmful changes in heart structure than overall body weight alone. The research, presented at the Radiological Society of North America annual meeting, suggests that male patients may be more vulnerable to structural effects of obesity on the heart.
A new tool trained on videos of expert surgeons offers students personalized advice as they practice suturing, showing significant improvement in skills. The AI model incorporates explainable AI to provide detailed feedback, enabling meaningful self-training and scaling up medical training.
Older adults with comorbid insomnia and sleep apnea demonstrated worse verbal memory performance than those with sleep apnea alone. Women showed a significant association between COMISA and worse verbal memory outcomes, while men did not. This finding suggests a potential hidden sleep-related pathway to cognitive decline in women.
A study of seven outpatient facilities found that 20-24% of all breast cancers diagnosed between 2014 and 2024 were in women aged 18-49. Invasive cancer cases accounted for 80.7%, often with aggressive types, challenging age-based screening cutoffs.
