DARIEN, IL – A new study to be presented at the SLEEP 2024 annual meeting is the first to find that episodic hypoxemia and hypoxic burden related to obstructive sleep apnea are associated with the risk of accelerated lung cancer reoccurrence. Results show that a 4% oxygen desaturation index of more than 15 and time spent in desaturation events were risk factors for cancer reappearance in less than two years. Measures of hypoxic burden such as time spent below 89% oxygen saturation, average oxygen saturation value below 89%, and single nadir oxygen levels, showed a similar association. After adjustment for potential confounders, average oxygen saturation below 89% and single minimum ...

Leuven, 4 June 2024 - Charcot-Marie-Tooth disease (CMT), a group of heritable disorders that affect the peripheral nerves, is marked by specific genetic changes. Research by the team of Prof. Ludo Van Den Bosch (VIB-KU Leuven) now reveals the effects of one such genetic cause. They found that the duplication of the gene PMP22 causes problems in the cell membrane of Schwann cells that provide the insulating cover for nerves. The results appeared in the journal Brain. Gene duplication in CMT1A Charcot-Marie-Tooth disease is a group of inherited disorders ...

   Herein, the O K-edge X-ray absorption spectroscopy (XAS) profile of an aqueous acetonitrile solution presented a distinct sharp peak not commonly observed in the corresponding profile of liquid water. Inner-shell calculations coupled with molecular dynamics simulations revealed that this sharp peak originated from isolated water molecules surrounded by acetonitrile molecules, rather than from water clusters. Hence, O K-edge XAS could facilitate the electronic-structural analysis of isolated water molecules, differentiating their contributions ...

Marmarth, ND – Three keen-eyed young fossil hunters made the discovery of a lifetime when they found the remains of a rare teenage Tyrannosaurus rex that could rewrite history, scientists and filmmakers announce today.  The boys -- brothers Liam and Jessin Fisher, 7 and 10 years old at the time, and their 9-year-old cousin, Kaiden Madsen -- spotted a large fossilized leg bone on a walk in the Hell Creek badlands area of North Dakota on July 31, 2022. Believing they had found a relatively common duckbill dinosaur, they sent a photo to family friend and Marmarth native Dr. Tyler Lyson, Associate Curator of Vertebrate Palaeontology at the Denver ...

The ovary is an essential organ for female fertility, and its age-dependent decline in function is a major cause of infertility. However, the molecular mechanisms underlying ovarian aging are still not well understood, particularly in higher vertebrates like primates. In this study, researchers used spatiotemporal transcriptomics to analyze the gene expression patterns in young and aged primate ovaries. Key findings from the study include: The study identified significant changes in DNA methylation associated with aging. Principal component analysis revealed a reduction in global ...

Optical waves propagating through air or multi-mode fiber can be patterned or decomposed using orthogonal spatial modes, with far-ranging applications in imaging, communication, and directed energy.

An international research team led by the Hong Kong University of Science and Technology (HKUST) has uncovered in a recent research project that people’s beliefs in science and religion are primarily shaped by the words of others, rather than their personal experiences. The study could help enhance public understanding of people’s belief formation in important scientific issues, such as climate change and vaccination. Conventionally, people are generally more confident about the existence of scientific phenomena, like oxygen, than religious phenomena, like God, as it is thought that people can experience oxygen, for instance, while it is harder to observe ...

Researchers have discovered sustained hunting by humans prevented the woolly rhinoceros from accessing favourable habitats as Earth warmed following the Last Ice Age. An international team of researchers, led by scientists from the University of Adelaide and University of Copenhagen, used computer modelling to make the discovery, shedding light on an aeons-old mystery. “Using computer models, fossils and ancient DNA, we traced 52,000 years of population history of the woolly rhinoceros across Eurasia at a resolution not previously considered possible,” said lead author Associate ...

Australians are no strangers to long, hot summers, but new Griffith University research has looked at the impact of hot weather on patients with pre-existing chronic diseases and how it increases their risk of being hospitalised. The research, recently published in eBioMedicine, found the risk of hospitalisation increased with the number of pre-existing chronic diseases during hot weather. Individuals over the age of 65 with multimorbidity, defined as having two or more chronic diseases, were most at risk during hot weather. Dr Zhiwei Xu from Griffith’s School ...

It’s often said we can’t control the weather. But what if the weather controls how and when we invest our money? More specifically, what if the skies control how much we’re willing to gamble in the stock market? New research by the University of South Australia has found a connection between pleasant weather conditions and higher investment in lottery-like stocks. Lottery-like stocks are cheap compared to other stocks and, like lottery tickets, they can be seen as an opportunity to make a substantial gain. However, the chance of a higher return is minimal, and it’s therefore considered a high-risk investment. A study by UniSA finance researchers ...
