Opioid-related overdose is now a leading cause of accidental death in the United States and Canada. A study suggests discontinuing prescribed opioids was associated with increased overdose risk.

A new analysis of more than 20,000 trees on five continents shows that old-growth trees are more drought tolerant than younger trees in the forest canopy and may be better able to withstand future climate extremes. The findings highlight the importance…

Early life experiences can impact the activity of our genes much later on and even affect longevity, finds a new study in fruit flies.

Immune T cells are continuing to target the spike protein of SARS-CoV-2 variants of concern, although mutations are making some T cells less effective, according to new research.

Changes in a single gene open the door for harmful gut bacteria to set off the inflammation that drives Crohn’s disease, according to a new study. These findings could one day help doctors better select targeted treatments for patients with this immune…

The effect of medicines on women and men can differ significantly. This also applies to the currently most promising anti-ageing drug rapamycin, as researchers have now shown. They report that the drug only prolongs the lifespan of female fruit flies, …

A new study have identified which blood tests are best at detecting Alzheimer’s disease during the earliest stages, and also other another blood test that are is optimal for detecting relevant treatment effects. These findings will speed up the develop…

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…
