Cancer risk following smoking cessation

JAMA Network Open

2024-02-06

(Press-News.org) About The Study: Sustained smoking cessation was associated with a significantly reduced risk of cancer after 10 years since quitting in this study of 2.9 million Korean adults. Quitting at any age helped reduce the cancer risk, and especially for lung cancer, early cessation before middle age exhibited a substantial risk reduction.

Authors: Jin-Kyoung Oh, Ph.D., of the National Cancer Center Graduate School of Cancer Science and Policy in Goyang, Republic of Korea, is the corresponding author.

Understanding the moon’s history with Chang’e-5 sample

2024-02-06

WASHINGTON, Feb. 6, 2024 – Earth’s moon achieved its Swiss cheese appearance from celestial objects crashing into its surface, forming impact craters. But craters weren’t all that was left behind; the intense pressure and temperature of such a collision also impacts the rocks and dust covering the lunar surface, known as regolith, altering its mineral composition and structure. Analyzing the resulting minerals provides modern researchers clues to the moon’s past. China’s Chang’e-5, the first lunar sample ...

Inner ear of miocene fossil ape gives clues to evolution of bipedalism

2024-02-06

A new study of a 7–8-million-year-old extinct fossil ape from China called Lufengpithecus offers new insights into the evolution of human bipedalism. The study, published in The Innovation, was conducted by a team from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences, the Yunnan Institute of Cultural Relics and Archaeology (YICRA), and New York University (NYU). Humans and our closest relatives, the living apes, display a remarkable diversity of locomotor abilities, from walking upright on two legs to climbing and clambering in trees to walking using all four limbs. Scientists have long been fascinated ...

GPT-3 transforms chemical research

2024-02-06

Artificial intelligence is growing into a pivotal tool in chemical research, offering novel methods to tackle complex challenges that traditional approaches struggle with. One subtype of artificial intelligence that has seen increasing use in chemistry is machine learning, which uses algorithms and statistical models to make decisions based on data and perform tasks that it has not been explicitly programmed for. However, to make reliable predictions, machine learning also demands large amounts of data, which isn’t always available in chemical research. Small chemical datasets simply do not provide enough information for these algorithms to train on, which limits their effectiveness. In ...

Guanine synthesis yields new insights into nitrogen’s role in nanocarbon catalysis

2024-02-06

In recent years, carbon-based catalysts — especially nitrogen-doped nanocarbons — have emerged as sustainable, reliable alternatives to the metal catalysts that have traditionally been used to support chemical reactions. Researchers from the Key Laboratory of Advanced Carbon-Based Functional Materials (Fujian Province University) at Fuzhou University synthesized nanocarbons from guanine molecules to better understand the precise role nitrogen plays in the carbon-based materials and explore the reaction mechanisms of these catalytic systems. In a recently published study, the research team clarified how different types of nitrogen can modulate oxidative dehydrogenation ...

Baseline findings among hospitalized mucormycosis patients —— A multicentric ambispective cohort study in India

2024-02-06

Mucormycosis is a relatively rare but serious fungal infection increasingly recognised for its poor prognosis and high mortality. Due to the COVID-19 pandemic, the incidence of mucormycosis reached high levels during 2021–2022 in India. This study led by Dr. Rizwan Suliankatchi Abdulkader (Indian Council of Medical Research) established a multicentric ambispective cohort of patients hospitalised with mucormycosis across India and reported their baseline profile, clinical characteristics, and outcomes at discharge. Mucormycosis was diagnosed based on mycological confirmation on direct microscopy (KOH/Calcofluor white stain), ...

New DNA methylation-based method for precise assessment of pancreas cell composition

2024-02-06

Research introduces new DNA methylation-based method for accurately assessing cell composition in the human pancreas, addressing a critical gap in diabetes research. By overcoming limitations of traditional protein marker-based approaches, the study provides a more precise means to identify specific cell types. The findings offer insights into beta-cell dysfunction across diabetes types and have direct clinical implications, enhancing our understanding of diabetes development and potentially guiding more tailored treatment ...

Remarkable cellular architecture and phylogenetic position of the mysterious arm-swinging protist meteora sporadica

2024-02-06

Tsukuba, Japan—Meteora sporadica is a small, unicellular eukaryote (protist) that was discovered in deep Mediterranean sea sediments in 2002. It differs from known protists by the presence of two lateral arms that swing back and forth. However, the ultrastructure and phylogenetic position of M. sporadica remain unknown. In this study, researchers successfully cultured and analyzed two strains of M. sporadica from marine sediments in detail. Ultratructural observations revealed ...

Mechanism of plants obtain nitrogen by supplying iron to symbiotic bacteria

2024-02-06

Tsukuba, Japan—Leguminous plants have a mechanism (rhizobial symbiosis) to efficiently acquire nitrogen, which is an essential macronutrient for growth, through the nitrogen-fixing bacteria rhizobia. Root nodules are organs on plant roots that facilitate the symbiotic relationship. Rhizobia coloniza these nodules and fix nitrogen by converting nitrogen from air into ammonia. Iron is needed for the enzymes that catalyze nitrogen fixation; however, where and how iron is transported to the nodule and used for nitrogen fixation is largely unknown. In this study, using the legume model plant Lotus japonicus, a transcriptome ...

Powerful answers to energy questions may be blowing in the wind

2024-02-06

While wind farms have become a widely popular method of generating energy, researchers are now looking at the impact of these large farms on wind patterns and the surrounding environment. Using large-scale simulations to better understand the way air moves across and within wind farms, researchers from UBC Okanagan and Delft University of Technology (TU Delft) in the Netherlands have developed a modelling framework that will help improve wind energy forecasts and productivity. The researchers also hope to learn how large wind farms can alter natural wind patterns. “Wind farms are getting so large that ...
