Neuroscientists have discovered that a specific type of brain cell could be a key player in making you feel the negative impacts of stress.

An international team of researchers has discovered a new genetic mutation that leads to childhood glaucoma, and in the process, uncovered a new mechanism for causing the disease. They hope their findings can lead to better screening for families affec…

Long COVID patients can experience many of the same lingering negative effects on their physical, mental, and social well-being as those experienced by people who become ill with other, non-COVID illnesses. Researchers found that 40 percent of the COVI…

Scientists have found that neurons from people with Alzheimer’s disease show deterioration and undergo a late-life stress process called senescence. These neurons have a loss of functional activity, impaired metabolism, and increased brain inflammation…

Small species such as herring, sardines and anchovies are the cheapest source of nutritious fish found in many low and middle-income countries, and are often caught in large volumes in the waters of nations where people are experiencing malnutrition, r…

Researchers invent new method to treat obesity by using cationic nanomaterials that can target specific areas of fat and inhibit the unhealthy storage of enlarged fat cells.

A new theory suggests irritable bowel syndrome (IBS), the most common gastrointestinal disorder, may be caused by gravity. An expert explains that IBS — and many other conditions — could result from the body’s inability to manage gravity.

Using smart technology to monitor the health, reproductivity, location, and environmental conditions of cattle can help with food safety and supply chain efficiency, but this monitoring adds energy cost to an already highly emissive industry. To combat…

There are large geographical differences in both how frequently resistant genes occur and in which types of bacteria the genes are found. This is shown by analyses of sewage from throughout the globe, thus underlining the importance of combating antimi…

Researchers are a step closer to identifying ways to support clinicians in predicting drug treatment outcomes for patients with visceral leishmaniasis in Brazil.

Underwater cameras have revealed the impressive range of skills nurse sharks use when feeding.

A new study shows how plants ‘encode’ specific chemistries of their lignin to grow tall and sustain climate changes: each plant cell uses different combinations of the enzymes LACCASEs to create specific lignin chemistries. These results can be used bo…

Thanks to laboratory produced human mini-retinas, researchers were able to observe complex changes in the retina as they occur in macular degeneration. This enabled them to discover the so-called cell extrusion as a potential mechanism for neurodegener…

A medication used to treat MS also has a beneficial effect on the composition of the intestinal flora, according to researchers. Conversely, the gut flora also plays a role in which side effects occur during treatment with the medication.

Researchers say they have created a laboratory-grown three-dimensional ‘organoid’ model that is derived from human tissue and designed to advance understanding about how early stages of cancer develop at the gastroesophageal junction (GEJ) — the point…

A link has been found between joint hypermobility and the emergence of depression and anxiety in adolescence, according to a new study. Researchers found that young people with joint hypermobility were more likely to have depression and anxiety, and th…

Sinks and P-traps are home to a surprising number of fungal organisms.

It was believed that it was impossible to differentiate the enantiomers of a chiral molecule using helical light beams — until now that is. Researchers have now developed a new chiroptical technique to differentiate the two non-superimposable mirror i…

A new analysis showed that early signs of liver damage from high-dose green tea extract were somewhat predicted by one variation in a genotype and strongly predicted by another variation.

Clean hydrogen energy is a good alternative to fossil fuels and is critical for achieving carbon neutrality. Researchers around the world are looking for ways to enhance the efficiency and lower the cost of hydrogen production, particularly by improvin…
