A combination of atmospheric measurements and fine-scale simulations has improved understanding of the modeling anomalies that arise when the model resolution approximates the length scale of turbulence features — an atmospheric simulation problem known as Terra Incognita.

When the global community is expected to meet for the second part of the UN Biodiversity Conference in Kunming, China, in autumn, it must also adopt the next generation of UN biodiversity targets.
Endangered and threatened insects and spiders, as well as common species that provide valuable ecological services, can be easily purchased – without adequate oversight – through basic internet searches, according to a new Cornell University study.
An artificial intelligence (AI) tool developed by Cedars-Sinai investigators accurately predicted who would develop pancreatic cancer based on what their CT scan images looked like years prior to being diagnosed with the disease. The findings, which may help prevent death through early detection of one of the most challenging cancers to treat, are published in the journal Cancer Biomarkers.
Freshwater pearl mussels are found in rivers in Japan.
In Chaos, researchers propose using a complex-network-based clustering workflow to search for synchronized structures of extreme rainfall events within the context of atmospheric chaos. By doing this, they were able to reconstruct a functional climate network to encode the underlying interaction of the climate system. Clusters on the network revealed regions of similar climatological behaviors. This means extreme rainfalls within different locations are not independent of each other but have a certain degree of similarity.
In Chaos, researchers in China created a network model drawn from the traffic index and air quality index of 21 cities across six regions in their country to quantify how traffic emissions from one city affect another. They leveraged data from COVID-19 lockdown procedures to better explain the relationship between traffic and air pollution and turned to a weighted climate network framework to model each city as a node using data from 2019 and 2020. They added a two-layer network that incorporated different regions, lockdown stages, and outbreak levels.
由妙佑医疗国际(Mayo Clinic)领导的一个国际研究小组报告称，人工智能将结直肠癌筛查中癌前息肉的漏诊率降低了两倍。这项研究已在《胃肠病学》杂志上发表。
Microplastics are a pathway for pathogens on land to reach the ocean, with likely consequences for human and wildlife health, according to a study from the University of California, Davis.
Mount Sinai researchers have discovered a previously unknown mechanism in which not-yet-malignant cells from early breast cancer tumors travel to other organs and, eventually, “turn on” and become metastatic breast cancer.
Although stream restoration filters pollutants out of local waterways and improves the health of the Chesapeake Bay, Baltimore area neighborhoods where it would do the most for water quality are far less willing to pay for such projects, according to a new study by a University of Maryland environmental economist and an interdisciplinary team of colleagues.
ولاية فلوريدا- أفاد فريق من الباحثين الدوليين بقيادة مايو كلينك أن الذكاء الاصطناعي قلل بمقدار الضِعف من معدل إغفال السلائل محتملة التسرطن في فحص سرطان القولون والمستقيم. هذه الدراسة منشورة في مجلة طب الجهاز الهضمي.
For nearly four decades, scientists have known that protons and neutrons cozily bundled up inside an atom’s nucleus are different from those roaming free in the cold emptiness of space. Now, for the first time, nuclear physicists at the Department of Energy’s Thomas Jefferson National Accelerator Facility have shown that while both particles are altered by their residence inside a nucleus, they may be affected differently.
A inteligência artificial reduziu em duas vezes a taxa de pólipos pré-cancerosos não identificados no exame de triagem de câncer colorretal, relatou uma equipe internacional de pesquisadores liderados pela Mayo Clinic. O estudo foi publicado na revista científica Gastroenterology.
La inteligencia artificial redujo a la mitad la tasa de pólipos precancerosos que se pasan por alto en la detección del cáncer colorrectal, informó un equipo compuesto por investigadores internacionales y dirigido por Mayo Clinic. El estudio se publicó en Gastroenterology.
A study is the first to examine if sex significantly affects cognitive outcomes in people who follow individually-tailored, multi-domain clinical interventions. The study also determined whether change in risk of developing cardiovascular disease (CVD) and Alzheimer’s disease (AD), along with blood markers of AD risk, also were affected by sex. Results showed that while care in an Alzheimer's Prevention Clinic setting is equally effective at improving cognitive function in both women and men, the personally-tailored interventions used by the researchers led to greater improvements in women compared to men across AD and CVD disease risk scales, as well blood biomarkers of risk such as blood sugar, LDL cholesterol, and the diabetes test HbA1C. Findings are important because women are disproportionately affected by AD and population-attributable risk models suggest that managing risk factors can prevent up to one-third of dementia cases.
Undertreatment with thyroid hormone replacement can put patients with hypothyroidism at risk for worse hospital outcomes, including longer length of stay and higher rates of readmission, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology and Metabolism.
Drought and the potential increase in the number of droughts worldwide due to climate change remains a concern for scientists. A recent study led by Stony Brook University researchers suggests that human migration due to droughts will increase by at least 200 percent as we move through the 21st Century.
People who learn they are autistic when they are younger may have a heightened quality of life and sense of well-being in adulthood.
