A teen's mental health, as well as their body mass index (BMI) and screen time, is significantly associated with sleep quality, according to a new paper published in PLOS One by Jianying Li of Shanxi University in China and colleagues. The study also found that girls and adolescents living in more rural areas tend to have lower sleep quality.
Children's mental health may be indirectly harmed by their mothers' experience of a major disaster, through the financial and social losses the disaster causes, according to a new study published in PLOS One by Ariane Lisann Rung of the University of Nebraska Medical Center, US, and colleagues.
Arctic fjords are among the most efficient natural systems for absorbing and storing carbon long term. However, as the Arctic is warming about four times faster than the global average, fjord ecosystems are changing rapidly. Against this backdrop, understanding the biological processes that regulate carbon storage is becoming increasingly important. Yet the microbial mechanisms that control whether carbon is stored in sediments or returned to the environment are still not fully understood.
Researchers at the Medical University of Vienna have described a mechanism in metastatic colorectal cancer that has received little attention to date: A key target of existing therapies, the so-called epidermal growth factor receptor (EGFR), is likely to affect more than just the cancer cells themselves. The study shows that EGFR also influences certain immune cells in the tumor microenvironment—and thereby helps determine how effectively the body's own defenses can combat the tumor. The findings have recently been published in the journal Cell Death & Differentiation.
A publication led by researchers from the Max Planck Institute for Marine Microbiology in Bremen, Germany, shows that microscopic partnerships between ciliates and bacteria play a role in the nitrogen cycle of lakes. The study, published in The ISME Journal, investigates what determines the ecological niche of the remarkable symbiosis, and how strongly the host depends on its microbial partners.
For many older adults, aging well means remaining independent—being able to do everyday activities like buying groceries or cooking dinner without help. A new Yale School of Medicine study suggests that changes in mental, physical or sensory capacity may be linked to a person's future ability to perform these routine tasks. The study is published in The Lancet Healthy Longevity.
Deep in the Atlantic, a vast circulation of water carries heat from the tropics toward Greenland. This is the Atlantic meridional overturning circulation, or Amoc. It does this work largely out of sight, so it doesn't have the public profile of rainforests, polar ice caps or other huge climate-regulating systems.

Each year, about 60% of all foodborne illness outbreaks in the U.S. occur in restaurants. While inspections performed by local health officials routinely identify food safety risks and violations, the information collected is typically used to address compliance issues at individual establishments rather than as a broader public health tool.
We're still in the definition phase of the Habitable Worlds Observatory (HWO), but it seems like every week a new research group comes out with a paper helping to shape what is becoming one of the most important space telescopes of the 2040s. A new paper posted to the arXiv preprint server from a team of researchers led by Daniel Jaffe of the University of Texas at Austin contributes to this ongoing definition work by arguing that it's time HWO adopted a high-resolution near-IR spectroscopy capability—which sounds great in practice, but so far hasn't been attempted because of technological limitations. But, according to the paper, two recent inventions finally make a working version of an extremely high-resolution exoplanet hunter viable.
Resurrecting dinosaurs using DNA retrieved from a mosquito trapped in amber is a great movie plot, though it's less likely to happen in the real world. However, researchers have been trying to unlock the secrets behind the evolution of a single protein family to understand the evolution of ancestral proteins.
By applying machine-learning models to single-cell brain recordings taken from humans in conversation, a research team identified both individual and collective neuronal activity that reflected key features of language. The work, published in Nature, offers unprecedented insight into how neurons encode linguistic information, suggesting that brain activity may one day be used to infer speech-related thoughts, which could be transformative for some patients.
AI is growing fast, and keeping up means building more data centers, manufacturing advanced chips and powering the tech behind it. All of that comes with a carbon cost. AI advocates claim that in the long run, AI will save energy and cut carbon emissions across global industries.
A new study of two supernova remnants, the debris left behind after stars explode, suggests the explosions came from stellar siblings that once orbited each other. The first star’s detonation sent its binary companion hurtling through space, and then, after traveling for thousands of years, the surviving star blew up too. “Using 16 years of […] The post NASA’s Fermi Mission Uncovers Possible Sibling Supernova Remnants appeared first on NASA Science.
Luigi Mangione plans to assert a psychiatric defense at his state murder trial, claiming he was suffering from extreme emotional disturbance when he gunned down UnitedHealthcare CEO Brian Thompson.
Researchers from National Taiwan University (NTU) and National Taiwan University Hospital (NTUH) have identified a promising way to reinvigorate the body's cancer-fighting immune cells by rewiring their metabolism, revealing a potential new strategy for cancer immunotherapy.
Husker scientists have developed a new swine influenza vaccination technique whose low cost and adaptability can greatly strengthen disease protection.
People become much less concerned about being better off than other people when health enters the picture, according to new research.
Frontline employees who face rude or disrespectful customers are more likely to justify negative behaviors, from cutting corners to leaving their jobs, according to a new study.
Antiplatelet drugs are one of the main tools used to prevent thrombus formation in people who have had a heart attack or stroke or who have cardiovascular diseases with a high thrombotic risk. These treatments work by reducing platelets' ability to aggregate and form clots that can obstruct the arteries. However, their use also increases the risk of bleeding, a common complication that limits their use in certain patients and remains one of the major challenges in cardiology today.
