Researchers at the University of Washington found that summer sea ice in the Last Ice Area, a region north of Greenland and Canadian Arctic Archipelago, is declining due to global warming. The study suggests that this area may not be as resilient as previously thought, raising concerns for polar bears and walruses that rely on the ice.
Researchers at Max Planck Institute successfully rebuilt the kinetochore, a complex assembly of proteins that binds to microtubules, in vitro. The reconstruction is a significant milestone in understanding how the kinetochore functions and paves the way for creating synthetic chromosomes.
A recent study suggests that near-death experiences (NDEs) in humans may be linked to evolutionary mechanisms, specifically thanatosis - the phenomenon of death-feigning or tonic immobility. This defense mechanism is thought to have arisen as a survival strategy in animals and has been preserved across various species, including humans.
A new study by R&D at British American Tobacco found that switching to exclusive use of glo resulted in significant reductions in exposure to toxicants and indicators of potential harm compared to continuing to smoke. The study showed similar reductions in biomarkers as those who stopped smoking completely.
The American Society of Nephrology and KidneyCure support a diverse group of researchers advancing kidney disease knowledge. Investigators funded by KidneyCure are making significant contributions in areas impacting millions of people living with kidney diseases.
A recent study found that nearly all patients with cancer developed good immune responses to COVID-19 mRNA vaccines, with 94% developing antibodies. However, a small subset of high-risk patients showed no response, raising concerns about future vaccination strategies.
A University of Houston study finds that plastic drapes can lower hypothermia rates in premature babies during PICC placement. This innovative nursing intervention shows promise in improving thermoregulation for VLBW neonates.
Researchers identified that multiciliated cells in the nasal epithelium are the first cells targeted by SARS-CoV-2 in early COVID-19 infection. These cells serve as the main factories for mass-producing viruses, highlighting the potential for targeting these cells using specific treatments to curb infections.
UD scientists and collaborators issue an urgent call to action on plastics pollution, highlighting the need for a circular lifecycle for plastics. The team proposes new approaches to chemistry, engineering, industrial processes, policy, and global collaboration to address the crisis.
The UOC's RLAB-UOC enables students to conduct practical experiments with real electronic and communications equipment remotely. The study found that students rate the laboratory and working with real tools positively, improving their learning experience and acquiring practical skills.
The new method uses a simple unit consisting of two rotating mirrors to form projections from multiple angles, bypassing the need to acquire image stacks. This allows for real-time imaging without physically moving the specimen or requiring expensive computer hardware.
University of Illinois engineers develop physics-informed neural networks to predict outcomes of complex 3D printing processes. The model accurately recreates experiments and predicts temperature and melt pool length with high accuracy.
A massive exome-wide association study identifies rare gene coding variants strongly associated with BMI, including GPR75, which confers protection from obesity in mouse models. This finding provides potential therapeutic targets for treating obesity and demonstrates the power of massive-scale exome sequencing.
Researchers at EPFL and UCSB successfully integrate ultralow-loss Si3N4 photonic integrated circuits with semiconductor lasers, enabling chip-scale frequency combs for high-capacity transceivers, data centers, and sensing applications. This breakthrough paves the way for large-volume, low-cost manufacturing of soliton microcombs.
A study found that prenatal exposure to THC and CBD affects the development of mice's brain, leading to impaired response to fluoxetine. The results suggest caution when using CBD during pregnancy.
A systematic analysis of probabilistic cost forecasts from expert-based and model-based methods reveals that current forecasts underestimates the pace of technological change. Model-based approaches outperformed expert elicitations in capturing observed costs, but both underestimated technological progress in most energy technologies.
Researchers at ETH Zurich have produced a crystal consisting exclusively of electrons, overcoming previous obstacles due to the low mass and high motional energy of electrons. The team used light to excite excitons in the semiconductor layer, allowing them to visualize the periodic arrangement of electrons.
The Laacher See volcano eruption occurred 13,077 years ago, according to revised dating, providing crucial information about historical climate fluctuations. This revised date coincides with observed temperature drops in Greenland Ice Sheet cores and has significant implications for European climate archives.
Researchers trained a blind individual to recognize objects using soundscapes, revealing novel topographic maps in the brain. This finding sheds light on the brain's ability for change and holds promise for helping people restore lost function after a stroke.
Nanosized molecules of a particular chemical element can inhibit the formation of plaque in brain tissues, providing hope for novel treatments of neurodegenerative diseases. The discovery was made by researchers at Umeå University in collaboration with colleagues in Croatia and Lithuania.
Researchers found that reducing PTHrP levels can prevent metastasis and improve survival in mice with pancreatic cancer. The study also showed promising results with anti-PTHrP antibodies targeting human pancreatic cancer cells, offering a new potential treatment approach.
A recent study published by the European Society of Cardiology found that older patients with heart failure are less likely to receive recommended therapies and dosages compared to their younger counterparts. The study analyzed data from the Swedish Heart Failure Registry and found that age was independently associated with undertreatm...
A study with healthcare workers found that most individuals retain anti-Spike antibodies for at least one year after infection, suggesting a long-lasting immune response. Vaccine-generated immunity is also expected to be long-lasting, according to the research.
Great snipes and great reed warblers have been found to fly at much higher altitudes during the day than at night, with one bird reaching an altitude of 8,700 meters. This pattern may be a general trait among migratory birds, which could help explain their behavior and migration patterns.
Researchers found that people with milder COVID-19 symptoms tend to have more killer T cells that recognize peptides shared with other coronaviruses, indicating a previous encounter. This may help explain why some individuals are more resilient to infection and potentially predict severe symptoms.
A study by Newcastle University highlights the difficulties people with smell and taste disorders face in accessing treatment. The research found that only around 20% of patients reported an improvement in symptoms following treatment, while over 60% suffered from anxiety or depression.
Research reveals warm-blooded fish swim approximately 1.6 times faster than their cold-blooded counterparts, but don't live in broader temperature ranges, making them susceptible to climate change impacts.
