University of Oklahoma engineer awarded NIH grant to design algorithms for studying cancer initiation

University of Oklahoma engineer awarded NIH grant to design algorithms for studying cancer initiation
2023-10-30
(Press-News.org) Marmar Moussa, Ph.D., an assistant professor of computer science professor at the University of Oklahoma, has secured a nearly $1 million award from the National Institutes of Health to advance her work in computational genomics.

The study, titled “Computational approaches to the mechanistic elucidation of the serrated pathway of human colon carcinogenesis,” aims to unravel the mechanisms driving the serrated pathway of human colon carcinogenesis using computational methods that help explain how colon cancer develops.

“This research is essential due to the intricacies involved in colon cancer initiation. Colon cancer often originates through various mechanisms, including mutations and genetic changes that lead to abnormal lesions known as precursor lesions,” Moussa said. “Some of these lesions, such as hyperplastic polyps, are well understood and pose minimal risk. However, others, like serrated lesions, remain less understood and require in-depth investigation.”

Serrated lesions are characterized by their unique microscopic appearance, displaying a distinctive saw-toothed pattern, Moussa says. Her research develops computational methods to model the progression of such lesions into tumors, a process known as carcinogenesis. By examining RNA molecules in these regions and identifying specific signatures, she hopes to shed light on how these lesions evolve, ultimately leading to cancer.

The research will use spatial transcriptomics, a technology that studies complex cellular environments and that will provide molecular profiles of individual cells within tissue context. The technology allows scientists to gain a better understanding of how cells interact within the tissue, their spatial arrangement and their role in the development of cancer, Moussa says. “By data generated by spatial transcriptomics, we can identify complex patterns and signatures associated with evolving lesions.”

Despite advancements in colorectal cancer prevention, it remains the second leading cause of cancer-related deaths in the United States. Moussa notes that the alternative serrated pathway of colon carcinogenesis, characterized by serrated lesions, has been underexplored due to its complexity and the lack of comprehensive data.

“The research project not only advances an understanding of colon cancer but also has the potential to impact the study of other cancer types,” Moussa said.

About the project: The agreement, from Aug. 1, 2023, to July 31, 2028, is funded by the National Institutes of Health and administered by the National Cancer Institute. The project, titled “Computational approaches to the mechanistic elucidation of the serrated pathway of human colon carcinogenesis,” receives $198,721 annually under Award No. 1K25CA270079-01A1.

Offset markets: New approach could help save tropical forests by restoring faith in carbon credits

Offset markets: New approach could help save tropical forests by restoring faith in carbon credits
2023-10-30
A new approach to valuing the carbon storage potential of natural habitats aims to help restore faith in offset schemes, by enabling investors to directly compare carbon credit pricing across a wide range of projects. Current valuation methods for forest conservation projects have come under heavy scrutiny, leading to a crisis of confidence in carbon markets. This is hampering efforts to offset unavoidable carbon footprints, mitigate climate change, and scale up urgently needed investment in tropical forest conservation. Measuring the value of carbon storage is not easy. Recent research revealed that as little as 6% of carbon credits ...

Window to avoid 1.5°C of warming will close before 2030 if emissions are not reduced

2023-10-30
**CORRECTION** We have identified an error in this press release. The fifth paragraph of the release originally read: The researchers warn that if carbon dioxide emissions remain at 2022 levels of about 40 billion gigatonnes per year, the carbon budget will be exhausted by around 2029, committing the world to warming of 1.5°C above preindustrial levels. However, this should read: The researchers warn that if carbon dioxide emissions remain at 2022 levels of about 40 gigatonnes per year, the carbon budget will be exhausted ...

Why all languages have words for ‘this’ and ‘that’

2023-10-30
Why all languages have words for ‘this’ and ‘that’ Languages around the world have words for ‘this’ and ‘that’ according to new research from an international team, led by the University of East Anglia. Researchers studied more than 1,000 speakers of 29 different languages to see how they use demonstratives – words that show where something is in relation to a person talking such as ‘this cat’ or ‘that dog’. It was previously thought that languages vary in the spatial distinctions they make - and that speakers of different languages may think in fundamentally different ...

Low-income countries could lose 30% of nutrients like protein and omega-3 from seafood due to climate change

2023-10-30
The nutrients available from seafood could drop by 30 per cent for low-income countries by the end of the century due to climate change, suggests new UBC research. That’s in a high carbon emissions and low mitigation scenario, according to the study published today in Nature Climate Change. This could be reduced to a roughly 10 per cent decline if the world were to meet the Paris Agreement targets of limiting global warming to 1.5 to 2 degrees Celsius - which recent reports have shown we’re not on track to achieve. “Low-income countries and the global south, ...

New species of mosasaur named for Norse sea serpent

New species of mosasaur named for Norse sea serpent
2023-10-30
Scientists have discovered a new species of mosasaur, large, carnivorous aquatic lizards that lived during the late Cretaceous. With “transitional” traits that place it between two well-known mosasaurs, the new species is named after a sea serpent in Norse mythology, Jormungandr, and the small North Dakota city Walhalla near to where the fossil was found. Details describing Jǫrmungandr walhallaensis are published today in the Bulletin of the American Museum of Natural History.  “If you put flippers on a Komodo dragon and made it really big, that’s basically what it would have looked like,” said the study’s lead ...
