A better way to study ocean currents（图）
洋流 机器学习模型 塑料污染 漏油
2023/6/20
To study ocean currents, scientists release GPS-tagged buoys in the ocean and record their velocities to reconstruct the currents that transport them. These buoy data are also used to identify “diverg...
Study: AI models fail to reproduce human judgements about rule violations（图）
人工智能模型 通用数据收集 机器学习模型 决策
2023/6/20
In an effort to improve fairness or reduce backlogs, machine-learning models are sometimes designed to mimic human decision making, such as deciding whether social media posts violate toxic content po...
People have more efficient conversations, use more positive language and perceive each other more positively when using an artificial intelligence-enabled chat tool, a group of Cornell researchers has...
Study shows how machine learning could predict rare disastrous events, like earthquakes or pandemics（图）
机器学习 自然灾害 顺序采样技术
2023/6/26
Researchers from Brown and MIT suggest how scientists can circumvent the need for massive data sets to forecast extreme events with the combination of an advanced machine learning system and sequentia...
Cancer is characterized by a number of key biological processes known as the “hallmarks of cancer,” which remodel cells and their immediate environment so that tumors can form, grow, and thrive. Many ...
Topological materials, an exotic class of materials whose surfaces exhibit different electrical or functional properties than their interiors, have been a frontier of research in the past decade — a f...
近日，中南大学湘雅医院骨科/国家老年疾病临床医学研究中心雷光华教授、曾超教授团队在骨关节疾病临床防治领域取得的重要研究成果“Association between gut microbiota and elevated serum urate in two independent cohorts”（基于两项独立队列探讨肠道菌群与血尿酸升高的相关性研究），再次在专业领域顶级期刊《Arthritis ...
The word lists packaged and shared amongst researchers to measure for bias in online texts often carry words, or “seeds,” with baked-in biases and stereotypes, which could skew their findings, new Cor...
Study: Global cancer risk from burning organic matter comes from unregulated chemicals（图）
燃烧有机物 全球癌症风险 PAH暴露
2023/6/8
Whenever organic matter is burned, such as in a wildfire, a power plant, a car’s exhaust, or in daily cooking, the combustion releases polycyclic aromatic hydrocarbons (PAHs) — a class of pollutants t...

New study offers insight on how resistance training burns fat
resistance movement reduced fat adipocyte metabolism
2021/8/10
Findings from a new study add to growing evidence that resistance exercise has unique benefits for fat loss. Researchers found that resistance-like exercise regulates fat cell metabolism at a molecula...
The first-ever molecular images of an olfactory receptor at work answer decades-old questions about odor recognition.
Frequent consumption of peanuts by cancer patients may increase risk of cancer spread, study finds
peanut PNA cancer cell spread
2021/8/6
A study has identified new factors accompanying previous findings that frequent consumption of peanuts by cancer patients could increase risk of cancer spread.
