Cholangiocarcinoma is an aggressive cancer that begins in the bile ducts. While the cancer is relatively rare, affecting approximately 8,000 people in the United States each year, unfortunately, it is often undiagnosed until an advanced stage. This late diagnosis makes cholangiocarcinoma very challenging to treat, and less than 10% of patients survive for five years after diagnosis. Traditional anti-cancer treatments, such as chemotherapy, have only limited effectiveness in cholangiocarcinoma, a...

Hypertrophic cardiomyopathy (or HCM for short) is a serious heart condition that involves thickening of the heart muscle wall and disruption of the normal tissue architecture, called ‘disarray’. This can result in sudden cardiac death caused by abnormal heart rhythms, known as arrhythmias. Identifying those HCM patients who are most at risk could permit preventative measures, such as implanting a cardioverter-defibrillator, which could potentially be lifesaving. However, current techniques to pr...

Our hearing is amongst our most profound senses, connecting us to the surrounding world through sound. However, this connection is diminished or absent altogether in millions of people around the world because of hearing loss. Hearing loss is a common sensory disorder and is often hereditary. The condition can be caused by complex genetic factors, and so far, researchers have linked over 150 genes to hearing impairment. Now, a new collaborative study led by Dr. Qiang Wang of the South China Univ...

Humans aren’t the only species that use tools, many animals do. Our closest relatives, the great apes, have long been known for their intelligence and ability to manipulate objects in their environment. Among the great apes, orangutans stand out for their complex tool use, which may hold important clues about how early human technologies evolved. A recent Outlook article authored by Dr. Robert Shumaker and Dr. Christopher Martin, both of the Indianapolis Zoo, delves into the existing research in...

Neuromorphic computing is a powerful tool for identifying time-varying patterns, but is often less effective than some AI-based techniques for more complex tasks. Researchers at the iCAS Lab directed by Ramtin Zand at the University of South Carolina, work on an NSF CAREER project to show how the capabilities of neuromorphic systems could be improved by blending them with specialized machine learning systems, without sacrificing their impressive energy efficiency. Using their approach, the team ...

Aging is a tale written by the cells in our bodies, although some cell types play a bigger role than others. At the crux of this story is an intriguing protagonist: the stem cell. These master builders, which can differentiate into any cell type, thereby helping to replace diseased or worn-out tissues, are essential for tissue repair and in maintaining health into old age. But as we get older, the capabilities of stem cells gradually diminish, which is known as stem cell exhaustion and is a key ...

A future where injured or diseased organs can be removed and replaced with new lab-printed tissues that are customized specifically for each patient is not as far away as you might think. These functional and living tissues could grow naturally within the body, and repair and sustain themselves over time. While these concepts were once in the realm of science fiction, advances in bioprinting, which is a form of 3D printing using biological “inks” (known as bioinks) loaded with living cells, are ...

Learning a new language as an adult is challenging, especially when the new language has features that differ significantly from one's native tongue. This phenomenon is key to a new study led by Professor Shanshan Yan at Peking University, which examines how language learning is affected when learners encounter features in their second language that are similar to those in their first language.

Liver disease is a significant health challenge globally. It can often progress unnoticed for years until it becomes life-threatening. Cirrhosis is the final stage of chronic liver diseases, and it can be caused by conditions such as viral hepatitis, excessive alcohol consumption, or metabolic-associated steatotic liver disease, which is linked to conditions such as obesity or diabetes. Once cirrhosis has set in, the tissue in the liver becomes permanently scarred, reducing its function, and thi...

For decades, works of science fiction have explored how the universe’s most fundamental speed limit could be broken by warping the fabric of spacetime. Through his experiments, Dr. Chance Glenn, founder of Morningbird Space Corporation, believes he may have discovered how spacetime can be distorted by extreme electric fields, which can be easily created in the lab. If his theory is correct, it would mean that the concept of ‘warp drives’ which allow us to travel at faster than the speed of light...

Much of the world’s rainfall is triggered by the transport of moisture along corridors high up in the atmosphere. Through fresh analysis of historical climate data, Luis Gimeno-Sotelo and colleagues at the University of Vigo have shown for the first time how the causes of certain droughts can be directly linked with a lack of moisture being transported along these corridors. Their results could help climate scientists to better predict when and where droughts will occur in the future.

Our kidneys filter blood to remove waste and can regulate water balance. We’ve all experienced that when we're thirsty urine becomes concentrated, signalling us to drink more water. When we drink excess water, we urinate more frequently, and the urine is diluted. The kidneys’ ability to concentrate or dilute urine according to our body’s need relies on countercurrent multiplication (or CCM), a complex process that generates a salt concentration gradient in the kidney. However, CCM is challenging...
