Memory, learning and decision-making studied in worms

As anyone who has ever procrastinated knows, remembering that you need to do something and acting on that knowledge are two different things. To understand how learning changes nerve cells and leads to different behaviors, researchers studied the much simpler nervous system of worms. “In this study, we can now […]

AI technique detects cancer ‘drivers,’ ‘passengers’

Scientists have made major advances in understanding and developing treatments for many cancers by identifying genetic mutations that drive the disease. Now, a team led by researchers at Weill Cornell Medicine, NewYork-Presbyterian and the New York Genome Center (NYGC) has developed a machine learning technique for detecting other modifications to DNA that have a […]

Solving the Peroxisome Puzzle

The ability to make membrane-bound organelles is a defining characteristic of eukaryotic cells — cells that constitute the bodies of all animals, plants and fungi on Earth. Membranes create enclosures that provide specialized environments for certain structures and their functions, such as the nuclei that store genetic information, or the […]

Tiniest of moments proves key for baby's healthy brain

University of Virginia School of Medicine researchers have shed new light on how our brains develop, revealing that the very last step in cell division is crucial for the brain to reach its proper size and function. The new findings identify a potential contributor to microcephaly, a birth defect in […]

Researchers reveal key information about how genes turn on and off

Human bodies have roughly 30,000 genes dictating not only how we look, but also critical biological processes. Now, a Florida State University and Australia National University research team has discovered a key aspect of gene regulation and ultimately how that process is implicated in cancer. Jonathan Dennis, an associate professor […]

Researchers create cellular blueprint of healthy lungs

The primary function of the lung is to facilitate the transfer of oxygen to the bloodstream. Crucial to this lifegiving task are endothelial cells, which line blood vessels permeating the lung and through which gas exchange occurs. Malfunction of these cells is implicated in a range of different diseases, including […]

Head and neck cancer cells hijack nearby healthy tissue, promoting further invasion of cancer cells

Up to half of patients with head and neck squamous cell carcinoma will experience tumor recurrence or new tumors—tumors that often spread and are difficult to treat. A team of scientists led by the University of Michigan School of Dentistry identified a mechanism by which head and neck cancer cells […]

Final results of SPRINT study confirm controlling blood-pressure critically important in preventing heart disease and stroke

Follow-up data from the landmark SPRINT study of the effect of high blood pressure on cardiovascular disease have confirmed that aggressive blood-pressure management—lowering systolic blood pressure to less than 120 mm Hg—dramatically reduces the risk of heart disease, stroke and death from these diseases, as well as death from all […]
