Ovarian cancer: New biological markers found that may predict which patients won"t respond to chemotherapy
Using a novel proteogenomic strategy and a variety of machine learning tools, investigators from the Icahn School of Medicine at Mount Sinai and colleagues have identified a 64-protein signature that may predict a subset of ovarian cancer patients wh.....»»
Researchers develop deep-learning model that outperforms Google AI system to predict peptide structures
Researchers at the University of Toronto have developed a deep-learning model, called PepFlow, that can predict all possible shapes of peptides—chains of amino acids that are shorter than proteins, but perform similar biological functions......»»
Study projects loss of brown macroalgae and seagrasses with global environmental change
Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role of seaweeds and seagrasses in coastal ecosystems, and.....»»
Aging Might Not Be Inevitable
There are biological underpinnings to aging—and so researchers are investigating cell manipulations, transfusions of young blood, and chemical compounds that can mimic low-calorie diets......»»
Phytochemical diversity and herbivory are higher in tropical forests, says study
It is widely accepted that biological interactions are stronger or more important in generating and maintaining biodiversity in the tropics than in temperate regions. However, this hypothesis has not been fully tested in ecology and evolutionary biol.....»»

Scientists discover genetic "off switch" in legume plants that limits biological ability to source nutrients
A genetic "off switch" that shuts down the process in which legume plants convert atmospheric nitrogen into nutrients has been identified for the first time by a team of international scientists......»»
Researchers develop highly accurate carbohydrate binding site prediction algorithm, DeepGlycanSite
As the most abundant organic substances in nature, carbohydrates are essential for life. Carbohydrates interact with diverse protein families to modulate various biological processes, including immune response, cell differentiation and neural develop.....»»
Boosting "natural killer" cell activity could improve cancer therapy
Yale researchers have uncovered a way to make a type of white blood cells known as natural killer cells—which kill infected, damaged, or malignant cells in the body—more effective against cancer. The approach, they say, could enable new treatment.....»»
Public health beliefs predict support for climate action, study shows
A paper published in the current issue of the Journal of Health Communication by Annenberg Public Policy Center (APPC) researchers finds evidence that holding science-consistent beliefs about the public health effects of climate change is an importan.....»»
Geological archives may predict our climate future
By analyzing 56-million-year-old sediments, a UNIGE team has measured the increase in soil erosion caused by global warming, synonymous with major flooding......»»
AI-based approach matches protein interaction partners
Proteins are the building blocks of life, involved in virtually every biological process. Understanding how proteins interact with each other is crucial for deciphering the complexities of cellular functions, and has significant implications for drug.....»»
Revolutionary Alzheimer’s Treatments Can’t Help Patients Who Go Undiagnosed
It’s a question of when, not if, highly effective treatments become available, says the CEO of Alzheimer’s Research UK. But that doesn’t solve the problem of one-third of dementia patients still going undiagnosed......»»
Ethylene oxide emissions from two plants could have raised cancer risks for Illinois residents, report shows
People living near two Lake County industries could face significantly greater risks of developing certain cancers, according to a new federal study based on monitoring of ethylene oxide pollution in surrounding neighborhoods......»»
New insights into methyl jasmonate-induced saponin biosynthesis in the balloon flower
Platycodon grandiflorus, commonly known as balloon flower, is renowned for its medicinal properties, primarily due to its rich saponin content. Saponins are known for their anti-inflammatory, anti-cancer, and immune-boosting properties, making P. gra.....»»
Biophysicists decipher functionality of adrenaline-binding receptor
G protein-coupled receptors (GPCRs) are found throughout the human body and are involved in many complex signaling pathways. Despite their importance in many biological processes, the central mechanism of G protein-coupling and the associated signal.....»»
