Gene mutations caused by exposure to certain chemical compounds have been linked to the development of gliomas, the most common type of malignant brain tumor. New research reveals that among patients with gliomas, these mutations are more common in firefighters than in individuals with other occupations. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society. The gene mutations of interest in this study make up a mutational pattern or “signature” that other investigators previously associated with exposure to haloalkanes, which ...

With soaring egg prices and ongoing bird flu headlines, many parents are uncertain about the risks and facts surrounding the virus, a national poll suggests. Most parents say they don’t know if there have been cases of bird flu in their state, and less than half feel that they are able to find accurate and current information about it, according to the University of Michigan Health C.S. Mott Children’s Hospital National Poll on Children’s health. “Many parents may hear about bird flu in the news but don’t feel well-informed or know if they should be taking action to protect their families,” said Mott Poll Co-Director Sarah Clark, M.P.H. “This ...

A University of Oxford study has determined that the widely used tools available to businesses for assessing their biodiversity impacts depend on broad assumptions and can have large uncertainties that are poorly understood or communicated. If used appropriately, they can be powerful tools to help guide effective action to address biodiversity loss – but if not, they can lead to misguided effort and can be insufficient for robust biodiversity strategy design. Businesses across a range of industries and sectors are under growing pressure to develop biodiversity strategies that not only minimise their negative impacts but ...

Politicians learned this lesson a long time ago: a well-placed joke is a valuable tool for capturing public attention and building trust. Scientists, however, are much more reluctant to use humor when engaging in science communication. They may fear that a lighthearted approach could make them seem less authoritative and, consequently, make scientific findings appear less credible. The good news, however, is that science itself seems to contradict this assumption. A new study led by Alexandra Lynn Frank, a ...

Krapivsky drew inspiration from the famous “secretary problem” or “optimal marriage problem”. In one of its many versions, a princess must choose her future husband from a pool of 100 candidates at a grand reception. However, strict rules apply: she may meet only one suitor at a time and has limited time to get to know him. At the end of each encounter, she must decide immediately whether to accept or reject the suitor. She cannot revisit previous candidates, nor can she ask any of them to wait while she considers others. How can the princess hope to make the best choice? The secret lies in a number: 37, to be precise (raise your hand if you ...

High demand for eel combined with decline in stock have resulted in soaring prices for this food item, which in many cultures, is considered a delicacy. This has fuelled a concern globally as the prized food item is now being illegally traded from Europe to Asia. Current research has focused on the critically endangered Anguilla anguilla, commonly known as the European eel. While its export outside the European Union is tightly regulated, large quantities of A. anguilla juveniles continue to be smuggled ...

A new study examining the effects of sleep patterns and shift work on the immune system has found that sleep debt and night shifts increase the risk of several common infections in nurses.  Modern society relies on shift work, which requires employees to work outside of traditional hours. While essential in sectors such as healthcare, growing evidence suggests that these work patterns may negatively impact worker’s health.  This study, which analysed self-reported data from 1,335 Norwegian nurses, found that shift work – particularly night shifts – was associated with a higher risk of several infections, including the ...

CHICAGO — A new scientific study provides many new insights into the biology of the prehistoric gigantic shark, Megalodon or megatooth shark, which lived nearly worldwide 15-3.6 million years ago. Paleobiology professor Kenshu Shimada of DePaul University led the study along with 28 other shark, fossil, and vertebrate anatomy experts around the globe. Findings from the study will be published in the journal “Palaeontologia Electronica.” Formally called Otodus megalodon, it is primarily known only from its serrated teeth, vertebrae, ...

The megalodon has long been imagined as an enormous great white shark, but new research suggests that perception is all wrong. The study finds the prehistoric hunter had a much longer body—closer in shape to a lemon shark or even a large whale. The study team, which included researchers from University of California, Riverside and across the globe, used a novel approach to estimate the shark’s total body length, moving beyond traditional methods that rely primarily on tooth size. By examining megalodon’s vertebral column and comparing ...

A new review article highlights the transformative role of circular RNA (circRNA) in cancer, revealing its potential as both a key player in tumor biology and a promising avenue for future therapies. Once thought to be noncoding RNA, circRNA has now been shown to encode functional proteins, challenging conventional RNA biology and opening up novel therapeutic possibilities. Unlike traditional messenger RNA, circRNAs form a continuous loop, lacking the typical 5' cap and 3' tail. This unique structure was originally believed to preclude them from protein translation. However, recent discoveries demonstrate that specific internal ribosome entry sites (IRES) and N6-methyladenosine ...

Lung cancer remains one of the leading causes of cancer-related mortality, with lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC) representing the most prevalent subtypes of non-small cell lung cancer (NSCLC). Despite their classification under the same umbrella, these two forms of lung cancer exhibit distinct genetic landscapes, therapeutic targets, and treatment responses. Recent advancements in next-generation gene sequencing have identified key driver genes that differentiate LUAD and LUSC, influencing their respective clinical management approaches. LUAD is frequently associated ...
